Boston, MA 02110-1301 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17.

Then, in your Docker container entry point script launch the service with *-d* to run it in the background, set the appropriate environment variables as described above, and launch your container's main application. - -The only bit of complexity is configuring which virtual network to join. ZeroTier's service automatically joins networks that have `.conf` files in `ZTHOME/networks.d` even if the `.conf` file is empty. So one way of doing this very easily is to add the following commands to your Dockerfile or container entry point script: - - mkdir -p /var/lib/zerotier-one/networks.d - touch /var/lib/zerotier-one/networks.d/8056c2e21c000001.conf - -Replace 8056c2e21c000001 with the network ID of the network you want your container to automatically join. It's also a good idea in your container's entry point script to add a small loop to wait until the container's instance of ZeroTier generates an identity and comes online. This could be something like: - - /var/lib/zerotier-one/zerotier-sdk-service -d - while [ ! -f /var/lib/zerotier-one/identity.secret ]; do - sleep 0.1 - done - # zerotier-sdk-service is now running and has generated an identity - -(Be sure you don't bundle the identity into the container, otherwise every container will try to be the same device and they will "fight" over the device's address.) - -Now each new instance of your container will automatically join the specified network on startup. Authorizing the container on a private network still requires a manual authorization step either via the ZeroTier Central web UI or the API. We're working on some ideas to automate this via bearer token auth or similar since doing this manually or with scripts for large deployments is tedious. diff --git a/docs/faq.md b/docs/faq.md deleted file mode 100644 index 06be2e6..0000000 --- a/docs/faq.md +++ /dev/null @@ -1,89 +0,0 @@ -Frequently Asked Questions -====== - - -#### Why would I integrate ZeroTier into my app? - -The ZeroTier SDK is designed specifically for the developer that doesn't want to work with or deal with the headaches of writing a networking layer for their app. Integrating ZeroTier into your application will prevent you from having to figure out how to do the complex networking that your app might require. It will provide you with a secure, easy-to-use, P2P connectivity solution. - -##### Use in Mobile Apps -If you're writing a game and you'd like to give it the ability talk to other instances in a secure and fast manner, you can embed our library into your app and choose from a couple different APIs. If you're developing for iOS, you'll want to add our [iOS Framework](https://github.com/zerotier/ZeroTierSDK/tree/master/integrations/apple/example_app/iOS) to your project. If you're developing for Android, you'll need to add our [JNI library](https://github.com/zerotier/ZeroTierSDK/tree/master/integrations/android) to your project. Once your app starts up, a separate thread will start which contains the ZeroTier service and a network stack dedicated entirely to your app. Each of these integrations give your app two main options for talking over a ZeroTier network. The first is a "direct call" which is means you'll call functions such as `zt_socket(), zt_connect(), ...` which are reimplementations of the traditional [socket API](https://en.wikipedia.org/wiki/Berkeley_sockets). Alternatively we provide a SOCKS5 proxy server in a separate thread which you can turn on via `zt_start_proxy_server(...)`. And if you've already implemented your networking layer using the traditional socket API and you aren't using third-party libraries that need to make network calls, you can `zt_start_intercept()`. The intercept will essentially hijack your network calls and route them to our reimplementations. This has the advantage that you literally don't have to change a single line of your networking code to use ZeroTier. (NOTE, the intercept is *not* available on Android). - -##### Use in Desktop Apps -Desktop apps are a bit easier than mobile apps to integrate with ZeroTier and you'll have even more API options. The exact details vary slightly among the various [platforms/OSes we support](https://github.com/zerotier/ZeroTierSDK/tree/master/integrations), but generally you can either link the ZeroTier library into your application (same as mobile), you can use the built-in SOCKS5 proxy (same as mobile), you can use the intercept (so far tested on OSX, Linux), or you can use `LD_PRELOAD` to dynamically load just the intercept into each of your apps and all will talk to a single `zerotier-sdk-service` running on the local host. This last option is a good option if you don't have access to the source code of the application and thus cannot use the direct call or SOCKS5 proxy APIs. - -*** - - - - - - - -#### I want technical details on how this all works under the hood. - - Cool. Read [this](technical.md) and let us know [here](zerotier.com/community/) if you have any questions. - -*** - - - - - - - -#### I don't have access to my an app's source but I still want to embed ZeroTier into it. Is this possible? - - Yes! Since you can't build your app with our library you'll have to use the **Intercept** mode. This means that you will dynamically-load our library at runtime and it'll connect to the locally-running ZeroTier service and function just the same. - -*** - - - - - - -#### How do switch network stacks? - -We currently provide a driver for [picoTCP](http://www.picotcp.com/) and [lwIP](http://savannah.nongnu.org/projects/lwip/), and we recommend their useage in that order. Each one has its own pros and cons, if you experience strange behavior it might be worth it to test your app on a different stack. Use `SDK_PICOTCP=1` or `SDK_LWIP=1`. For more info, see: [Network Stacks](network_stacks.md) - -*** - - - - - - -#### Suitable for games? - -Yes. We think this solution is well suited for low-latency multiplayer games where reliability and ease of use are important. - -The ZeroTier protocol is inherently P2P and only falls back to a relay in the event that your direct link is interrupted. It's in our best interest to automatically find the quickest route for your data and to *not* handle your data. This has the obvious benefits of reduced latency for your game, but also provides you better security and control of your data and reduces our costs. It seems non-sensical to do it any other way. ZeroTier is not a "cloud" that you send all of your data to. - -We've just begun work on a native [Unity 3D](https://unity3d.com/) plugin to enable your Unity game to communicate over ZeroTier networks. You can check it out [here](../integrations/Unity3D) - -*** - - - - - - -#### Embedded Applications / IoT - -We foresee the largest application of the ZeroTier SDK to be embedded devices that require lightweight, efficient and reliable networking layers that are also secure and effortless to provision. We've specifically engineered the core service and the API library to be as lightweight and portable as possible. We'd like to see people retake control of their data and security by skipping the the "cloud" without adding complexity. - -*** - - - - - - -#### Controlling traffic? - -The SDK's interception of network calls is currently all or nothing. If engaged, the intercept library intercepts all network I/O calls and redirects them through the new path. A network-containerized application cannot communicate over the regular network connection of its host or container or with anything else except other hosts on its ZeroTier virtual LAN. Support for optional "fall-through" to the host IP stack for outgoing connections outside the virtual network and for gateway routes within the virtual network is planned. (It will be optional since in some cases total network isolation might be considered a nice security feature.) - -*** - - - - diff --git a/docs/img/api_diagram.png b/docs/img/api_diagram.png deleted

It will also build the IP stack as `build/lwip/liblwip.so`. - -The `zerotier-sdk-service` binary is almost the same as a regular ZeroTier One build except instead of creating virtual network ports using Linux's `/dev/net/tun` interface, it creates instances of a user-space TCP/IP stack for each virtual network and provides RPC access to this stack via a Unix domain socket. The latter is a library that can be loaded with the Linux `LD_PRELOAD` environment variable or by placement into `/etc/ld.so.preload` on a Linux system or container. Additional magic involving nameless Unix domain socket pairs and interprocess socket handoff is used to emulate TCP sockets with extremely low overhead and in a way that's compatible with select, poll, epoll, and other I/O event mechanisms. - -The intercept library does nothing unless the `ZT_NC_NETWORK` environment variable is set. If on program launch (or fork) it detects the presence of this environment variable, it will attempt to connect to a running `zerotier-sdk-service` at the specified Unix domain socket path. - -Unlike `zerotier-one`, `zerotier-sdk-service` does not need to be run with root privileges and will not modify the host's network configuration in any way. It can be run alongside `zerotier-one` on the same host with no ill effect, though this can be confusing since you'll have to remember the difference between "real" host interfaces (tun/tap) and network containerized endpoints. The latter are completely unknown to the kernel and will not show up in `ifconfig`. - - -#### Starting the SDK Service - -A simple test can be performed in user space (no root) in your own home directory. - -First, build the SDK service and intercept library as described above. Then create a directory to act as a temporary ZeroTier home for your test SDK service instance. You'll need to move the `liblwip.so` binary that was built with `make linux_shared_lib` into there, since the service must be able to find it there and load it. - - mkdir /tmp/sdk-test-home - cp -f build/lwip/liblwip.so /tmp/sdk-test-home - -Now you can run the service (no sudo needed, and `-d` tells it to run in the background): - - ./build/zerotier-sdk-service -d -p8000 /tmp/sdk-test-home - -As with ZeroTier One in its normal incarnation, you'll need to join a network for anything interesting to happen: - - ./build/zerotier-cli -D/tmp/sdk-test-home join 8056c2e21c000001 - -If you don't want to use [Earth](https://www.zerotier.com/public.shtml) for this test, replace 8056c2e21c000001 with a different network ID. The `-D` option tells `zerotier-cli` not to look in `/var/lib/zerotier-one` for information about a running instance of the ZeroTier system service but instead to look in `/tmp/sdk-test-home`. - -Now type: - - ./build/zerotier-cli -D/tmp/sdk-test-home listnetworks - -Try it a few times until you see that you've successfully joined the network and have an IP address. Instead of a *zt#* device, a path to a Unix domain socket will be listed for the network's port. - -Now you will want to have ZeroTier One (the normal `zerotier-one` build, not the SDK) running somewhere else, such as on another Linux system or VM. Technically you could run it on the *same* Linux system and it wouldn't matter at all, but many people find this intensely confusing until they grasp just what exactly is happening here. - -On the other Linux system, join the same network if you haven't already (8056c2e21c000001 if you're using Earth) and wait until you have an IP address. Then try pinging the IP address your SDK service instance received. You should see ping replies. - -Back on the host that's running `zerotier-sdk-service`, type `ip addr list` or `ifconfig` (ifconfig is technically deprecated so some Linux systems might not have it). Notice that the IP address of the network containers endpoint is not listed and no network device is listed for it either. That's because as far as the Linux kernel is concerned it doesn't exist. - -What are you pinging? What is happening here? - -The `zerotier-sdk-service` binary has joined a *virtual* network and is running a *virtual* TCP/IP stack entirely in user space. As far as your system is concerned it's just another program exchanging UDP packets with a few other hosts on the Internet and nothing out of the ordinary is happening at all. That's why you never had to type *sudo*. It didn't change anything on the host. - -Now you can run an application . - - export LD_PRELOAD=`pwd`/build/linux_shared_lib/libztintercept.so - export ZT_NC_NETWORK=/tmp/sdk-test-home/nc_8056c2e21c000001 - node tests/httpserver.js - -Also note that the "pwd" in `LD_PRELOAD` assumes you are in the ZeroTier source root and have built the SDK there. If not, substitute the full path to `libztintercept.so`. If you want to remove those environment variables later, use `unset LD_PRELOAD` and `unset ZT_NC_NETWORK`. - -If you don't have node.js installed, an alternative test using python would be: - - python -m SimpleHTTPServer 80 - -If you are running Python 3, use `-m http.server`. - -If all went well a small static HTTP server is now serving up the current directory, but only inside the network container. Going to port 80 on your machine won't work. To reach it, go to the other system where you joined the same network with a conventional ZeroTier instance and try: - - curl http://APP.SPECIFIC.IP.ADDR/ - -Replace `APP.SPECIFIC.IP.ADDR` with the IP address that `zerotier-sdk-service` was assigned on the virtual network.

* New PPP stack for lwIP, developed in ppp-new branch. - Based from pppd 2.4.5, released 2009-11-17, with huge changes to match - code size and memory requirements for embedded devices, including: - - Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which - is more or less what pppd sys-* files are, so that we get something working - using the unix port. - - Merged some patchs from lwIP Git repository which add interesting features - or fix bugs. - - Merged some patchs from Debian pppd package which add interesting features - or fix bugs. - - Ported PPP timeout handling to the lwIP timers system - - Disabled all the PPP code using filesystem access, replaced in necessary cases - to configuration variables. - - Disabled all the PPP code forking processes. - - Removed IPX support, lwIP does not support IPX. - - Ported and improved random module from the previous PPP port. - - Removed samba TDB (file-driven database) usage, because it needs a filesystem. - - MS-CHAP required a DES implementation, we added the latest PolarSSL DES - implementation which is under a BSD-ish license. - - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be - used in embedded devices with reduced memory footprint. - - Removed PPP configuration file parsing support. - - Added macro definition EAP_SUPPORT to make EAP support optional. - - Added macro definition CHAP_SUPPORT to make CHAP support optional. - - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional. - - Added macro definition PAP_SUPPORT to make PAP support optional. - - Cleared all Linux syscall calls. - - Disabled demand support using a macro, so that it can be ported later. - - Disabled ECP support using a macro, so that it can be ported later. - - Disabled CCP support using a macro, so that it can be ported later. - - Disabled CBCP support using a macro, so that it can be ported later. -

- Disabled PPP server support using a macro, so that it can be ported later. - - Switched all PPP debug to lwIP debug system. - - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere, - removed all global variables everywhere, did everything necessary for - the PPP stack to support more than one PPP session (pppd only support - one session per process). - - Removed the statically allocated output buffer, now using PBUF. - - Improved structure size of all PPP modules, deep analyze of code to reduce - variables size to the bare minimum. Switched all boolean type (char type in - most architecture) to compiler generated bitfields. - - Added PPP IPv6 support, glued lwIP IPv6 support to PPP. - - Now using a persistent netif interface which can then be used in lwIP - functions requiring a netif. - - Now initializing PPP in lwip_init() function. - - Reworked completely the PPP state machine, so that we don't end up in - anymore in inconsistent state, especially with PPPoE. - - Improved the way we handle PPP reconnection after disconnect, cleaning - everything required so that we start the PPP connection again from a - clean state. - - Added PPP holdoff support, allow the lwIP user to wait a little bit before - reconnecting, prevents connection flood, especially when using PPPoL2TP. - - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client - feature to lwIP, L2TP being a widely used tunnel protocol. - - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...) - - Added PPP API "sequential" thread-safe API, based from NETIFAPI. - - 2011-07-21: Simon Goldschmidt - * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes - ioctl/FIONREAD return the size of the next pending datagram. - - 2011-05-25: Simon Goldschmidt - * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c, - combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4 - and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP - code so that the code is more readable. - - 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt) - * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to - Ivan!

Initialization is done in lwip_init() with - build time options. DNS timer is added in tcpip_thread context. DHCP can set - DNS server ip addresses when options are received. You need to set LWIP_DNS=1 - in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get - some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo" - list with points to improve. - - 2007-11-06 Simon Goldschmidt - * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly - enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status - for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined. - - 2007-11-06 Simon Goldschmidt - * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include - core header files in api.h (ip/tcp/udp/raw.h) to hide the internal - implementation from netconn api applications. - - 2007-11-03 Frédéric Bernon - * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP & - RAW netconn.

This is a first release which have to be improve for TCP. Note it used the - netconn::recv_avail which need to be more "thread-safe" (note there is already - the problem for FIONREAD with lwip_ioctl/ioctlsocket). - - 2007-11-01 Frédéric Bernon, Marc Chaland - * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c: - Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api - layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api - layer. This option enable to delayed TCP PUSH flag on multiple "write" calls. - Note that previous "copy" parameter for "write" APIs is now called "apiflags". - - 2007-10-24 Frédéric Bernon - * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than - TCP_EVENT_xxx macros to get a code more readable.

Change the - common function to reduce a little bit the footprint (for all functions using - only the "netif" parameter). - - 2007-10-03 Frédéric Bernon - * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down, - netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce - a little bit the footprint (for all functions using only the "netif" parameter). - - 2007-09-15 Frédéric Bernon - * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF - option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for - netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for - IP_MULTICAST_TTL and IP_MULTICAST_IF. - - 2007-09-10 Frédéric Bernon - * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles - even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() - each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can - decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but - call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime() - or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro. - This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside - snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only - when it's queried (any direct call to "sysuptime" is changed by a call to - snmp_get_sysuptime). - - 2007-09-09 Frédéric Bernon, Bill Florac - * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP, - and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags - if you want IGMP on an interface. igmp_stop() is now called inside netif_remove(). - igmp_report_groups() is now called inside netif_set_link_up() (need to have - LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait - the next query message to receive the matching multicast streams). - - 2007-09-08 Frédéric Bernon - * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains - IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change). - Use this new field to access to common pcb fields (ttl, tos, so_options, etc...). - Enable to access to these fields with LWIP_TCP=0. - - 2007-09-05 Frédéric Bernon - * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h, - ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option - LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default). - Be careful, disabling ICMP make your product non-compliant to RFC1122, but - help to reduce footprint, and to reduce "visibility" on the Internet. - - 2007-09-05 Frédéric Bernon, Bill Florac - * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list - for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new - parameters have to be provided: a task name, and a task stack size. For this - one, since it's platform dependant, you could define the best one for you in - your lwipopts.h. For port maintainers, you can just add these new parameters - in your sys_arch.c file, and but it's not mandatory, use them in your OS - specific functions. - - 2007-09-05 Frédéric Bernon - * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings - inside init.c for task #7142 "Sanity check user-configurable values". - - 2007-09-04 Frédéric Bernon, Bill Florac - * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by - memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the - value). It will avoid potential fragmentation problems, use a counter to know - how many times a group is used on an netif, and free it when all applications - leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity - check if LWIP_IGMP!=0). - - 2007-09-03 Frédéric Bernon - * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement". - Initialize igmp_mac_filter to NULL in netif_add (this field should be set in - the netif's "init" function). Use the "imr_interface" field (for socket layer) - and/or the "interface" field (for netconn layer), for join/leave operations. - The igmp_join/leavegroup first parameter change from a netif to an ipaddr. - This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany). - - 2007-08-30 Frédéric Bernon - * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions - from api/api_lib". Now netbuf API is independant of netconn, and can be used - with other API (application based on raw API, or future "socket2" API). Ports - maintainers just have to add src/api/netbuf.c in their makefile/projects. - - 2007-08-30 Frédéric Bernon, Jonathan Larmour - * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check - user-configurable values". - - 2007-08-29 Frédéric Bernon - * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start. - igmp_start is call inside netif_add. Now, igmp initialization is in the same - spirit than the others modules. Modify some IGMP debug traces. - - 2007-08-29 Frédéric Bernon - * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function" - Add lwip_init function to regroup all modules initializations, and to provide - a place to add code for task #7142 "Sanity check user-configurable values". - Ports maintainers should remove direct initializations calls from their code, - and add init.c in their makefiles. Note that lwip_init() function is called - inside tcpip_init, but can also be used by raw api users since all calls are - disabled when matching options are disabled. Also note that their is new options - in opt.h, you should configure in your lwipopts.h (they are enabled per default). - - 2007-08-26 Marc Boucher - * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL - since they can under certain circumstances be called with an invalid conn - pointer after the connection has been closed (and conn has been freed). - - 2007-08-25 Frédéric Bernon (Artem Migaev's Patch) - * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up". - Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set. - - 2007-08-22 Frédéric Bernon - * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK - to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release. - - 2007-08-22 Frédéric Bernon - * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT & - ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the - name is tcpip_input (we keep the name of 1.2.0 function). - - 2007-08-17 Jared Grubb - * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool - settings into new memp_std.h and optional user file lwippools.h. This adds - more dynamic mempools, and allows the user to create an arbitrary number of - mempools for mem_malloc. - - 2007-08-16 Marc Boucher - * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function; - otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely - close the connection. - - 2007-08-16 Marc Boucher - * sockets.c: lwip_accept(): check netconn_peer() error return. - - 2007-08-16 Marc Boucher - * mem.c, mem.h: Added mem_calloc(). - - 2007-08-16 Marc Boucher - * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT) - for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG - and starving other message types. - Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API - - 2007-08-16 Marc Boucher - * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf - type and flgs (later renamed to flags). - Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*. - Improved lwip_recvfrom(). TCP push now propagated. - - 2007-08-16 Marc Boucher - * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global - provided by etharp. - - 2007-08-16 Marc Boucher - * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h, - etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c: - Added PPPoE support and various PPP improvements. - - 2007-07-25 Simon Goldschmidt - * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial, - making netbuf_copy_partial use this function. - - 2007-07-25 Simon Goldschmidt - * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with - 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and - other stacks. - - 2007-07-13 Jared Grubb (integrated by Frédéric Bernon) - * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add - a link callback in the netif struct, and functions to handle it. Be carefull - for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c) - if you want to be sure to be compatible with future changes... - - 2007-06-30 Frédéric Bernon - * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions. - - 2007-06-21 Simon Goldschmidt - * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both - LWIP_AUTOIP =0 and =1 to remove redundant code. - - 2007-06-21 Simon Goldschmidt - * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option - MEM_USE_POOLS to use 4 pools with different sized elements instead of a - heap. This both prevents memory fragmentation and gives a higher speed - at the cost of more memory consumption. Turned off by default. - - 2007-06-21 Simon Goldschmidt - * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of - netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into - int to be able to send a bigger buffer than 64K with one time (mainly - used from lwip_send). - - 2007-06-21 Simon Goldschmidt - * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write - into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too. - - 2007-06-21 Simon Goldschmidt - * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in - netconn_write from api_lib.c to api_msg.c to also prevent multiple context- - changes on low memory or empty send-buffer. - - 2007-06-18 Simon Goldschmidt - * etharp.c, etharp.h: Changed etharp to use a defined hardware address length - of 6 to avoid loading netif->hwaddr_len every time (since this file is only - used for ethernet and struct eth_addr already had a defined length of 6). - - 2007-06-17 Simon Goldschmidt - * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets - to disable UDP checksum generation on transmit. - - 2007-06-13 Frédéric Bernon, Simon Goldschmidt - * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid - pointers or parameters, and let the possibility to redefined it in cc.h. Use - this macro to check "conn" parameter in api_msg.c functions. - - 2007-06-11 Simon Goldschmidt - * sockets.c, sockets.h: Added UDP lite support for sockets - - 2007-06-10 Simon Goldschmidt - * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled - by default) to switch off UDP-Lite support if not needed (reduces udp.c code - size) - - 2007-06-09 Dominik Spies (integrated by Frédéric Bernon) - * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h: - AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and - LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt - (see TODO mark in the source code). - - 2007-06-09 Simon Goldschmidt - * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for - etharp_output() to match netif->output so etharp_output() can be used - directly as netif->output to save one function call. - - 2007-06-08 Simon Goldschmidt - * netif.h, ethernetif.c, slipif.c, loopif.c: Added define - NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables, - added initialization of those to ethernetif, slipif and loopif. - - 2007-05-18 Simon Goldschmidt - * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF - (defaulting to off for now) that can be set to 0 to send fragmented - packets by passing PBUF_REFs down the stack. - - 2007-05-23 Frédéric Bernon - * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP - connections, such present in patch #5959. - - 2007-05-23 Frédéric Bernon - * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx - code in only one part... - - 2007-05-18 Simon Goldschmidt - * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp - elements to overflow. This is achieved by adding some bytes before and after - each pool element (increasing their size, of course), filling them with a - prominent value and checking them on freeing the element. - Set it to 2 to also check every element in every pool each time memp_malloc() - or memp_free() is called (slower but more helpful). - - 2007-05-10 Simon Goldschmidt - * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for - PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce - code size. - - 2007-05-11 Frédéric Bernon - * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c: - Include a function pointer instead of a table index in the message to reduce - footprint. Disable some part of lwip_send and lwip_sendto if some options are - not set (LWIP_TCP, LWIP_UDP, LWIP_RAW). - - 2007-05-10 Simon Goldschmidt - * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus - \ extern "C" {' in all header files. Now you can write your application using - the lwIP stack in C++ and simply #include the core files. Note I have left - out the netif/ppp/*h header files for now, since I don't know which files are - included by applications and which are for internal use only. - - 2007-05-09 Simon Goldschmidt - * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library - memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for - situations where some compilers might inline the copy and save a function - call. Also replaced all calls to memcpy() with calls to (S)MEMCPY(). - - 2007-05-08 Simon Goldschmidt - * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc()) - to be overriden in case the C-library malloc implementation is not protected - against concurrent access. - - 2007-05-04 Simon Goldschmidt (Atte Kojo) - * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending - multiple packets to the same host. - - 2007-05-04 Frédéric Bernon, Jonathan Larmour - * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible - to corrupt remote addr/port connection state". Reduce problems "not enought memory" with - netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between - sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function. - Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct, - these fields are now renamed "addr" & "port". - - 2007-04-11 Jonathan Larmour - * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new - sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return - with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro - by the port in sys_arch.h if desired. - - 2007-04-06 Frédéric Bernon, Simon Goldschmidt - * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API - allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp - clients, using new functions from netifapi.h. Disable as default (no port change to do). - - 2007-04-05 Frédéric Bernon - * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant. - - 2007-04-04 Simon Goldschmidt - * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x) - use this for and architecture-independent form to tell the compiler you intentionally - are not using this variable. Can be overriden in cc.h. - - 2007-03-28 Frédéric Bernon - * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to - define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded - string, point on one of your's ethernetif field, or alloc a string you will free yourself). - It will be used by DHCP to register a client hostname, but can also be use when you call - snmp_set_sysname. - - 2007-03-28 Frédéric Bernon - * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to - initialize a network interface's flag with. It tell this interface is an ethernet - device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility - Support for IPv4" section 4.6) when interface is "up" with netif_set_up(). - - 2007-03-26 Frédéric Bernon, Jonathan Larmour - * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build - time if you only use PPP or SLIP. The default is enable. Note we don't have to call - etharp_init in your port's initilization sequence if you use tcpip.c, because this call - is done in tcpip_init function. - - 2007-03-22 Frédéric Bernon - * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the - new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in - your lwipopts.h. More, unused counters are not defined in the stats structs, and not - display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined - but never used. Fix msg_in.c with the correct #if test for a stat display. - - 2007-03-21 Kieran Mansley - * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com). - Provides callback on netif up/down state change. - - 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds - * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c, - ip.c, netif.h, tcpip.c, opt.h: - New configuration option LWIP_IGMP to enable IGMP processing. Based on only one - filter per all network interfaces. Declare a new function in netif to enable to - control the MAC filter (to reduce lwIP traffic processing). - - 2007-03-11 Frédéric Bernon - * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can - be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this - unless you know what you're doing (default are RFC1122 compliant). Note - that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds. - - 2007-03-08 Frédéric Bernon - * tcp.h: Keepalive values can be configured at compile time, but don't change - this unless you know what you're doing (default are RFC1122 compliant). - - 2007-03-08 Frédéric Bernon - * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h: - Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO - on UDP sockets/netconn. - - 2007-03-08 Simon Goldschmidt - * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time. - - 2007-03-06 Frédéric Bernon - * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h: - Implement SO_RCVTIMEO on UDP sockets/netconn. - - 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt) - * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated - on the stack and remove the API msg type from memp - - 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt) - * sockets.h, sockets.c: Move socket initialization to new - lwip_socket_init() function. - NOTE: this changes the API with ports. Ports will have to be - updated to call lwip_socket_init() now. - - 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt) - * api_lib.c: Use memcpy in netbuf_copy_partial. - - - ++ Bug fixes: - - 2008-03-17 Frédéric Bernon, Ed Kerekes - * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have - some problems to fill the IP header on some targets, use now the - ip.h macros to do it). - - 2008-03-13 Frédéric Bernon - * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using - (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a - TCP connection caused a crash. Note that using (lwip_)recvfrom - like this is a bit slow and that using (lwip)getpeername is the - good lwip way to do it (so, using recv is faster on tcp sockets). - - 2008-03-12 Frédéric Bernon, Jonathan Larmour - * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's - recv_raw() does not consume data", and the ping sample (with - LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom - returned the IP payload, without the IP header). - - 2008-03-04 Jonathan Larmour - * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors - and/or warnings on some systems where mem_size_t and size_t differ. - * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc. - - 2008-03-04 Kieran Mansley (contributions by others) - * Numerous small compiler error/warning fixes from contributions to - mailing list after 1.3.0 release candidate made. - - 2008-01-25 Cui hengbin (integrated by Frédéric Bernon) - * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures. - - 2008-01-15 Kieran Mansley - * tcp_out.c: BUG20511. Modify persist timer to start when we are - prevented from sending by a small send window, not just a zero - send window. - - 2008-01-09 Jonathan Larmour - * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid - conflict with Linux system headers. - - 2008-01-06 Jonathan Larmour - * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP - address entirely on receiving a DHCPNAK, and restarting discovery. - - 2007-12-21 Simon Goldschmidt - * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail - is not protected" by using new macros for interlocked access to modify/test - netconn->recv_avail. - - 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev) - * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state) - - 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm) - * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling - of silly window avoidance and prevent lwIP from shrinking the window) - - 2007-12-04 Simon Goldschmidt - * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last - data packet was lost): add assert that all segment lists are empty in - tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED - state from LAST_ACK in tcp_process - - 2007-12-02 Simon Goldschmidt - * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET - If including for system-struct timeval, LWIP_TIMEVAL_PRIVATE now - has to be set to 0 in lwipopts.h - - 2007-12-02 Simon Goldschmidt - * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always - allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen - netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox. - This is a fix for thread-safety and allocates all items needed for a netconn - when the netconn is created. - - 2007-11-30 Simon Goldschmidt - * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple - netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed - to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same - port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address) - - 2007-11-27 Simon Goldschmidt - * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by - letting ip_route only use netifs that are up. - - 2007-11-27 Simon Goldschmidt - * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF - and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and - sockets block most operations once they have seen a fatal error. - - 2007-11-27 Simon Goldschmidt - * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the - netif to send as an argument (to be able to send on netifs that are down). - - 2007-11-26 Simon Goldschmidt - * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs - arrive out-of-order - - 2007-11-21 Simon Goldschmidt - * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early - Fixed the nagle algorithm; nagle now also works for all raw API applications - and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY' - - 2007-11-12 Frédéric Bernon - * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most - of the netconn_peer and netconn_addr processing is done inside tcpip_thread - context in do_getaddr. - - 2007-11-10 Simon Goldschmidt - * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can - happen any time). Now the packet simply isn't enqueued when out of memory. - - 2007-11-01 Simon Goldschmidt - * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or - TCP_MSS if that is smaller) as long as no MSS option is received from the - remote host. - - 2007-11-01 Simon Goldschmidt - * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN) - is now based on TCP_MSS instead of pcb->mss (on passive open now effectively - sending our configured TCP_MSS instead of the one received). - - 2007-11-01 Simon Goldschmidt - * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was - calculated based on the configured TCP_MSS, not on the MSS option received - with SYN+ACK. - - 2007-10-09 Simon Goldschmidt - * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too - short and also was generated wrong if checksum coverage != tot_len; - receive: checksum was calculated wrong if checksum coverage != tot_len - - 2007-10-08 Simon Goldschmidt - * mem.c: lfree was not updated in mem_realloc! - - 2007-10-07 Frédéric Bernon - * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential - crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT: - this change cause an API breakage for netconn_addr, since a parameter - type change. Any compiler should cause an error without any changes in - yours netconn_peer calls (so, it can't be a "silent change"). It also - reduce a little bit the footprint for socket layer (lwip_getpeername & - lwip_getsockname use now a common lwip_getaddrname function since - netconn_peer & netconn_addr have the same parameters). - - 2007-09-20 Simon Goldschmidt - * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state) - by checking tcp_tw_pcbs also - - 2007-09-19 Simon Goldschmidt - * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies) - - 2007-09-15 Mike Kleshov - * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used) - - 2007-09-06 Frédéric Bernon - * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove - it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which - already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h" - if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h. - - 2007-08-30 Frédéric Bernon - * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces, - and fix some coding style. - - 2007-08-28 Frédéric Bernon - * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any - kind of packets. These packets are considered like Ethernet packets (payload - pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets - are considered like IP packets (payload pointing to iphdr). - - 2007-08-27 Frédéric Bernon - * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error - problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state - and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT). - - 2007-08-24 Kieran Mansley - * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy - compiler (Paradigm C++) - - 2007-08-09 Frédéric Bernon, Bill Florac - * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement. - Introduce IGMP_STATS to centralize statistics management. - - 2007-08-09 Frédéric Bernon, Bill Florac - * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast - packet on a udp pcb binded on an netif's IP address, and not on "any". - - 2007-08-09 Frédéric Bernon, Bill Florac - * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement. - This is mainly on using lookup/lookfor, and some coding styles... - - 2007-07-26 Frédéric Bernon (and "thedoctor") - * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages. - - 2007-07-25 Simon Goldschmidt - * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if - tcp_output fails in tcp_close, the code in do_close_internal gets simpler - (tcp_output is called again later from tcp timers). - - 2007-07-25 Simon Goldschmidt - * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old - copy_from_pbuf, which illegally modified the given pbuf. - - 2007-07-25 Simon Goldschmidt - * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs: - changed snd_queuelen++ to snd_queuelen += pbuf_clen(p). - - 2007-07-24 Simon Goldschmidt - * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the - correct state (must be CLOSED). - - 2007-07-13 Thomas Taranowski (commited by Jared Grubb) - * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed - allocation. It now returns NULL. - - 2007-07-13 Frédéric Bernon - * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in - all error cases. - - 2007-07-13 Frédéric Bernon - * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed, - because current code doesn't follow rawapi.txt documentation. - - 2007-07-13 Kieran Mansley - * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in - out of sequence processing of received packets - - 2007-07-03 Simon Goldschmidt - * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an - assumption is made that this pbuf is in one piece (i.e. not chained). These - assumptions clash with the possibility of converting to fully pool-based - pbuf implementations, where PBUF_RAM pbufs might be chained. - - 2007-07-03 Simon Goldschmidt - * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems - when closing tcp netconns: removed conn->sem, less context switches when - closing, both netconn_close and netconn_delete should safely close tcp - connections. - - 2007-07-02 Simon Goldschmidt - * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c, - tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off) - to cache ARP table indices with each pcb instead of single-entry cache for - the complete stack. - - 2007-07-02 Simon Goldschmidt - * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent - warnings when assigning to smaller types. - - 2007-06-28 Simon Goldschmidt - * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing. - - 2007-06-28 Simon Goldschmidt - * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if - a segment contained chained pbufs) - - 2007-06-28 Frédéric Bernon - * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute - a "pseudo-random" value based on netif's MAC and some autoip fields. It's always - possible to define this macro in your own lwipopts.h to always use C library's - rand(). Note that autoip_create_rand_addr doesn't use this macro. - - 2007-06-28 Frédéric Bernon - * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option - LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications - in api_lib/api_msg (use pointers and not type with table, etc...) - - 2007-06-26 Simon Goldschmidt - * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines. - - 2007-06-25 Simon Goldschmidt - * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload - for udp packets with no matching pcb. - - 2007-06-25 Simon Goldschmidt - * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match - could get udp input packets if the remote side matched. - - 2007-06-13 Simon Goldschmidt - * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get - changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0. - - 2007-06-13 Simon Goldschmidt - * api_msg.c: pcb_new sets conn->err if protocol is not implemented - -> netconn_new_..() does not allocate a new connection for unsupported - protocols. - - 2007-06-13 Frédéric Bernon, Simon Goldschmidt - * api_lib.c: change return expression in netconn_addr and netconn_peer, because - conn->err was reset to ERR_OK without any reasons (and error was lost)... - - 2007-06-13 Frédéric Bernon, Matthias Weisser - * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename - MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid - some macro names collision with some OS macros. - - 2007-06-11 Simon Goldschmidt - * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0, - create checksum over the complete packet. On RX, if it's < 8 (and not 0), - discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both - UDP & UDP Lite. - - 2007-06-11 Srinivas Gollakota & Oleg Tyshev - * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags" - where TCP flags wasn't initialized in tcp_keepalive. - - 2007-06-03 Simon Goldschmidt - * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function - registered, p->payload was modified without modifying p->len if sending - icmp_dest_unreach() (had no negative effect but was definitively wrong). - - 2007-06-03 Simon Goldschmidt - * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp - re-used the input pbuf even if that didn't have enough space to include the - link headers. Now the space is tested and a new pbuf is allocated for the - echo response packet if the echo request pbuf isn't big enough. - - 2007-06-01 Simon Goldschmidt - * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread. - - 2007-05-23 Frédéric Bernon - * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only - allocated by do_listen if success) and netconn_accept errors handling. In - most of api_lib functions, we replace some errors checkings like "if (conn==NULL)" - by ASSERT, except for netconn_delete. - - 2007-05-23 Frédéric Bernon - * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return - an error code if it's impossible to fetch a pbuf on a TCP connection (and not - directly close the recvmbox). - - 2007-05-22 Simon Goldschmidt - * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of - bound but unconnected (and non-listening) tcp_pcbs. - - 2007-05-22 Frédéric Bernon - * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only - used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of - sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features - like "sys_timeout" in their application threads. - - 2007-05-22 Frédéric Bernon - * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see - which parameters are used by which do_xxx function, and to avoid "misusing" - parameters (patch #5938). - - 2007-05-22 Simon Goldschmidt - * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938: - changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto - is only 8 bits wide. This affects the api, as there, the protocol was - u16_t, too. - - 2007-05-18 Simon Goldschmidt - * memp.c: addition to patch #5913: smaller pointer was returned but - memp_memory was the same size -> did not save memory. - - 2007-05-16 Simon Goldschmidt - * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns - != ERR_OK. - - 2007-05-16 Simon Goldschmidt - * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same - as the one of the netif used for sending to prevent sending from old - addresses after a netif address gets changed (partly fixes bug #3168). - - 2007-05-16 Frédéric Bernon - * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work - with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in - tcpip_init) because we have to be sure that network interfaces are already - added (mac filter is updated only in igmp_init for the moment). - - 2007-05-16 Simon Goldschmidt - * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls - into sys_arch_sem_wait calls to prevent timers from running while waiting - for the heap. This fixes bug #19167. - - 2007-05-13 Simon Goldschmidt - * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines - for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from - tcp.h to sockets.h. - - 2007-05-07 Simon Goldschmidt - * mem.c: Another attempt to fix bug #17922. - - 2007-05-04 Simon Goldschmidt - * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy() - implementation so that it can be reused (don't allocate the target - pbuf inside pbuf_copy()). - - 2007-05-04 Simon Goldschmidt - * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem - to save a little RAM (next pointer of memp is not used while not in pool). - - 2007-05-03 "maq" - * sockets.c: Fix ioctl FIONREAD when some data remains from last recv. - (patch #3574). - - 2007-04-23 Simon Goldschmidt - * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results - in NULL reference for incoming TCP packets". Loopif has to be configured - (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input() - (multithreading environments, e.g. netif->input() = tcpip_input()) or - putting packets on a list that is fed to the stack by calling loopif_poll() - (single-thread / NO_SYS / polling environment where e.g. - netif->input() = ip_input). - - 2007-04-17 Jonathan Larmour - * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold - the difference between two u16_t's. - * sockets.h: FD_SETSIZE needs to match number of sockets, which is - MEMP_NUM_NETCONN in sockets.c right now. - - 2007-04-12 Jonathan Larmour - * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580). - - 2007-04-12 Kieran Mansley - * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission - timer is reset to fix bug#19434, with help from Oleg Tyshev. - - 2007-04-11 Simon Goldschmidt - * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than - previously thought need to be copied (everything but PBUF_ROM!). Cleaned up - pbuf.c: removed functions no needed any more (by etharp). - - 2007-04-11 Kieran Mansley - * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix - "Constant is long" warnings with 16bit compilers. Contributed by - avatar@mmlab.cse.yzu.edu.tw - - 2007-04-05 Frédéric Bernon, Jonathan Larmour - * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on - the mailbox is active". Now, the post is only done during a connect, and do_send, - do_write and do_join_leave_group don't do anything if a previous error was signaled. - - 2007-04-03 Frédéric Bernon - * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output - packets. See patch #5834. - - 2007-03-30 Frédéric Bernon - * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add - missing pcb allocations checking (in do_bind, and for each raw_new). Fix style. - - 2007-03-30 Frédéric Bernon - * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with - others environment defines (these were too "generic"). - - 2007-03-28 Frédéric Bernon - * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call - result and can cause a crash. lwip_send now check netbuf_ref result. - - 2007-03-28 Simon Goldschmidt - * sockets.c Remove "#include " from sockets.c to avoid multiple - definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is - defined. This is the way it should have been already (looking at - doc/sys_arch.txt) - - 2007-03-28 Kieran Mansley - * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS + - IP and TCP headers *and* physical link headers - - 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov) - * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause - to send some garbage. It is not a definitive solution, but the patch does solve - the problem for most cases. - - 2007-03-22 Frédéric Bernon - * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used). - - 2007-03-22 Frédéric Bernon - * api_lib.c: somes resources couldn't be freed if there was errors during - netconn_new_with_proto_and_callback. - - 2007-03-22 Frédéric Bernon - * ethernetif.c: update netif->input calls to check return value. In older ports, - it's a good idea to upgrade them, even if before, there could be another problem - (access to an uninitialized mailbox). - - 2007-03-21 Simon Goldschmidt - * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed - by casting to unsigned). - - 2007-03-21 Frédéric Bernon - * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from - api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a - dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call. - Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a - faster and more reliable communication between api_lib and tcpip. - - 2007-03-21 Frédéric Bernon - * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0. - - 2007-03-21 Frédéric Bernon - * api_msg.c, igmp.c, igmp.h: Fix C++ style comments - - 2007-03-21 Kieran Mansley - * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS + - IP and TCP headers - - 2007-03-21 Kieran Mansley - * Fix all uses of pbuf_header to check the return value. In some - cases just assert if it fails as I'm not sure how to fix them, but - this is no worse than before when they would carry on regardless - of the failure. - - 2007-03-21 Kieran Mansley - * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and - comment out missing header include in icmp.c - - 2007-03-20 Frédéric Bernon - * memp.h, stats.c: Fix stats_display function where memp_names table wasn't - synchronized with memp.h. - - 2007-03-20 Frédéric Bernon - * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input, - tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with - network interfaces.

Instead, it is a pointer - to a '0.0.0.0' IP address. - - * The packet buffer implementation is changed. The pbuf->ref counter - meaning has changed, and several pbuf functions have been - adapted accordingly. - - * netif drivers have to be changed to set the hardware address length field - that must be initialized correctly by the driver (hint: 6 for Ethernet MAC). - See the contrib/ports/c16x cs8900 driver as a driver example. - - * netif's have a dhcp field that must be initialized to NULL by the driver. - See the contrib/ports/c16x cs8900 driver as a driver example. - -(0.5.x) This file has been unmaintained up to 0.6.1.

All include files are now - kept in a dedicated include/ directory. - - * The API now has proper error handling. A new function, - netconn_err(), now returns an error code for the connection in - case of errors. - - * Improvements in the memory management subsystem. The system now - keeps a pointer to the lowest free memory block. A new function, - mem_malloc2() tries to allocate memory once, and if it fails tries - to free some memory and retry the allocation. - - * Much testing has been done with limited memory - configurations. lwIP now does a better job when overloaded. - - * Some bugfixes and improvements to the buffer (pbuf) subsystem. - - * Many bugfixes in the TCP code: - - - Fixed a bug in tcp_close(). - - - The TCP receive window was incorrectly closed when out of - sequence segments was received.

This has been fixed. - - - Retransmitted segments now contain the correct acknowledgment - number and advertised window. - - - TCP retransmission timeout backoffs are not correctly computed - (ala BSD). After a number of retransmissions, TCP now gives up - the connection. - - * TCP connections now are kept on three lists, one for active - connections, one for listening connections, and one for - connections that are in TIME-WAIT. This greatly speeds up the fast - timeout processing for sending delayed ACKs. - - * TCP now provides proper feedback to the application when a - connection has been successfully set up. - - * More comments have been added to the code. The code has also been - somewhat cleaned up. - -(0.2) Initial public release. diff --git a/ext/lwip/COPYING b/ext/lwip/COPYING deleted file mode 100644 index e23898b..0000000 --- a/ext/lwip/COPYING +++ /dev/null @@ -1,33 +0,0 @@ -/* - * Copyright (c) 2001, 2002 Swedish Institute of Computer Science. - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without modification, - * are permitted provided that the following conditions are met: - * - * 1.

This is thread safe in all cases but you should avoid -passing data byte after byte because it uses heavy locking (mailbox) and it -allocates pbuf, better fill them ! - -if NO_SYS is 0 and if PPP_INPROC_IRQ_SAFE is 1, you may also use pppos_input() -from an RX thread, however pppos_input() is not thread safe by itself. You can -do that *BUT* you should NEVER call pppos_connect(), pppos_listen() and -ppp_free() if pppos_input() can still be running, doing this is NOT thread safe -at all.

Here is a callback example which -tries to mimic what we usually see on xDSL modems while they are negotiating -the link, which should be self-explanatory: - -static void ppp_notify_phase_cb(ppp_pcb *pcb, u8_t phase, void *ctx) { - switch (phase) { - - /* Session is down (either permanently or briefly) */ - case PPP_PHASE_DEAD: - led_set(PPP_LED, LED_OFF); - break; - - /* We are between two sessions */ - case PPP_PHASE_HOLDOFF: - led_set(PPP_LED, LED_SLOW_BLINK); - break; - - /* Session just started */ - case PPP_PHASE_INITIALIZE: - led_set(PPP_LED, LED_FAST_BLINK); - break; - - /* Session is running */ - case PPP_PHASE_RUNNING: - led_set(PPP_LED, LED_ON); - break; - - default: - break; - } -} - - - -6 Upgrading from lwIP <= 1.4.x to lwIP >= 2.0.x -=============================================== - -PPP API was fully reworked between 1.4.x and 2.0.x releases. However porting -from previous lwIP version is pretty easy: - -* Previous PPP API used an integer to identify PPP sessions, we are now - using ppp_pcb* control block, therefore all functions changed from "int ppp" - to "ppp_pcb *ppp" - -* struct netif was moved outside the PPP structure, you have to provide a netif - for PPP interface in pppoX_create() functions - -* PPP session are not started automatically after you created them anymore, - you have to call ppp_connect(), this way you can configure the session before - starting it. - -* Previous PPP API used CamelCase, we are now using snake_case. - -* Previous PPP API mixed PPPoS and PPPoE calls, this isn't the case anymore, - PPPoS functions are now prefixed pppos_ and PPPoE functions are now prefixed - pppoe_, common functions are now prefixed ppp_. - -* New PPPERR_ error codes added, check you have all of them in your status - callback function - -* Only the following include files should now be used in user application: - #include "netif/ppp/pppapi.h" - #include "netif/ppp/pppos.h" - #include "netif/ppp/pppoe.h" - #include "netif/ppp/pppol2tp.h" - - Functions from ppp.h can be used, but you don't need to include this header - file as it is already included by above header files. - -* PPP_INPROC_OWNTHREAD was broken by design and was removed, you have to create - your own serial rx thread - -* PPP_INPROC_MULTITHREADED option was misnamed and confusing and was renamed - PPP_INPROC_IRQ_SAFE, please read the "PPPoS input path" documentation above - because you might have been fooled by that - -* If you used tcpip_callback_with_block() on ppp_ functions you may wish to use - the PPPAPI API instead. - -* ppp_sighup and ppp_close functions were merged using an optional argument - "nocarrier" on ppp_close. - -* DNS servers are now only remotely asked if LWIP_DNS is set and if - ppp_set_usepeerdns() is set to true, they are now automatically registered - using the dns_setserver() function so you don't need to do that in the PPP - callback anymore. - -* PPPoS does not use the SIO API anymore, as such it now requires a serial - output callback in place of sio_write - -* PPP_MAXIDLEFLAG is now in ms instead of jiffies diff --git a/ext/lwip/doc/rawapi.txt b/ext/lwip/doc/rawapi.txt deleted file mode 100644 index ce5b42a..0000000 --- a/ext/lwip/doc/rawapi.txt +++ /dev/null @@ -1,506 +0,0 @@ -Raw TCP/IP interface for lwIP - -Authors: Adam Dunkels, Leon Woestenberg, Christiaan Simons - -lwIP provides three Application Program's Interfaces (APIs) for programs -to use for communication with the TCP/IP code: -* low-level "core" / "callback" or "raw" API. -* higher-level "sequential" API. -* BSD-style socket API. - -The raw API (sometimes called native API) is an event-driven API designed -to be used without an operating system that implements zero-copy send and -receive. This API is also used by the core stack for interaction between -the various protocols. It is the only API available when running lwIP -without an operating system. - -The sequential API provides a way for ordinary, sequential, programs -to use the lwIP stack. It is quite similar to the BSD socket API. The -model of execution is based on the blocking open-read-write-close -paradigm. Since the TCP/IP stack is event based by nature, the TCP/IP -code and the application program must reside in different execution -contexts (threads). - -The socket API is a compatibility API for existing applications, -currently it is built on top of the sequential API. It is meant to -provide all functions needed to run socket API applications running -on other platforms (e.g. unix / windows etc.). However, due to limitations -in the specification of this API, there might be incompatibilities -that require small modifications of existing programs. - -** Multithreading - -lwIP started targeting single-threaded environments. When adding multi- -threading support, instead of making the core thread-safe, another -approach was chosen: there is one main thread running the lwIP core -(also known as the "tcpip_thread"). When running in a multithreaded -environment, raw API functions MUST only be called from the core thread -since raw API functions are not protected from concurrent access (aside -from pbuf- and memory management functions). Application threads using -the sequential- or socket API communicate with this main thread through -message passing. - - As such, the list of functions that may be called from - other threads or an ISR is very limited! Only functions - from these API header files are thread-safe: - - api.h - - netbuf.h - - netdb.h - - netifapi.h - - pppapi.h - - sockets.h - - sys.h - - Additionaly, memory (de-)allocation functions may be - called from multiple threads (not ISR!) with NO_SYS=0 - since they are protected by SYS_LIGHTWEIGHT_PROT and/or - semaphores. - - Netconn or Socket API functions are thread safe against the - core thread but they are not reentrant at the control block - granularity level. That is, a UDP or TCP control block must - not be shared among multiple threads without proper locking. - - If SYS_LIGHTWEIGHT_PROT is set to 1 and - LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT is set to 1, - pbuf_free() may also be called from another thread or - an ISR (since only then, mem_free - for PBUF_RAM - may - be called from an ISR: otherwise, the HEAP is only - protected by semaphores). - - -** The remainder of this document discusses the "raw" API. ** - -The raw TCP/IP interface allows the application program to integrate -better with the TCP/IP code. Program execution is event based by -having callback functions being called from within the TCP/IP -code. The TCP/IP code and the application program both run in the same -thread. The sequential API has a much higher overhead and is not very -well suited for small systems since it forces a multithreaded paradigm -on the application. - -The raw TCP/IP interface is not only faster in terms of code execution -time but is also less memory intensive. The drawback is that program -development is somewhat harder and application programs written for -the raw TCP/IP interface are more difficult to understand. Still, this -is the preferred way of writing applications that should be small in -code size and memory usage. - -All APIs can be used simultaneously by different application -programs. In fact, the sequential API is implemented as an application -program using the raw TCP/IP interface. - -Do not confuse the lwIP raw API with raw Ethernet or IP sockets. -The former is a way of interfacing the lwIP network stack (including -TCP and UDP), the later refers to processing raw Ethernet or IP data -instead of TCP connections or UDP packets. - -Raw API applications may never block since all packet processing -(input and output) as well as timer processing (TCP mainly) is done -in a single execution context. - ---- Callbacks - -Program execution is driven by callbacks functions, which are then -invoked by the lwIP core when activity related to that application -occurs. A particular application may register to be notified via a -callback function for events such as incoming data available, outgoing -data sent, error notifications, poll timer expiration, connection -closed, etc. An application can provide a callback function to perform -processing for any or all of these events. Each callback is an ordinary -C function that is called from within the TCP/IP code. Every callback -function is passed the current TCP or UDP connection state as an -argument. Also, in order to be able to keep program specific state, -the callback functions are called with a program specified argument -that is independent of the TCP/IP state. - -The function for setting the application connection state is: - -- void tcp_arg(struct tcp_pcb *pcb, void *arg) - - Specifies the program specific state that should be passed to all - other callback functions. The "pcb" argument is the current TCP - connection control block, and the "arg" argument is the argument - that will be passed to the callbacks. - - ---- TCP connection setup - -The functions used for setting up connections is similar to that of -the sequential API and of the BSD socket API. A new TCP connection -identifier (i.e., a protocol control block - PCB) is created with the -tcp_new() function. This PCB can then be either set to listen for new -incoming connections or be explicitly connected to another host. - -- struct tcp_pcb *tcp_new(void) - - Creates a new connection identifier (PCB). If memory is not - available for creating the new pcb, NULL is returned. - -- err_t tcp_bind(struct tcp_pcb *pcb, ip_addr_t *ipaddr, - u16_t port) - - Binds the pcb to a local IP address and port number. The IP address - can be specified as IP_ADDR_ANY in order to bind the connection to - all local IP addresses. - - If another connection is bound to the same port, the function will - return ERR_USE, otherwise ERR_OK is returned. - -- struct tcp_pcb *tcp_listen(struct tcp_pcb *pcb) - - Commands a pcb to start listening for incoming connections. When an - incoming connection is accepted, the function specified with the - tcp_accept() function will be called. The pcb will have to be bound - to a local port with the tcp_bind() function. - - The tcp_listen() function returns a new connection identifier, and - the one passed as an argument to the function will be - deallocated. The reason for this behavior is that less memory is - needed for a connection that is listening, so tcp_listen() will - reclaim the memory needed for the original connection and allocate a - new smaller memory block for the listening connection. - - tcp_listen() may return NULL if no memory was available for the - listening connection. If so, the memory associated with the pcb - passed as an argument to tcp_listen() will not be deallocated. - -- struct tcp_pcb *tcp_listen_with_backlog(struct tcp_pcb *pcb, u8_t backlog) - - Same as tcp_listen, but limits the number of outstanding connections - in the listen queue to the value specified by the backlog argument. - To use it, your need to set TCP_LISTEN_BACKLOG=1 in your lwipopts.h. - -- void tcp_accepted(struct tcp_pcb *pcb) - - Inform lwIP that an incoming connection has been accepted. This would - usually be called from the accept callback. This allows lwIP to perform - housekeeping tasks, such as allowing further incoming connections to be - queued in the listen backlog. - ATTENTION: the PCB passed in must be the listening pcb, not the pcb passed - into the accept callback! - -- void tcp_accept(struct tcp_pcb *pcb, - err_t (* accept)(void *arg, struct tcp_pcb *newpcb, - err_t err)) - - Specified the callback function that should be called when a new - connection arrives on a listening connection. - -- err_t tcp_connect(struct tcp_pcb *pcb, ip_addr_t *ipaddr, - u16_t port, err_t (* connected)(void *arg, - struct tcp_pcb *tpcb, - err_t err)); - - Sets up the pcb to connect to the remote host and sends the - initial SYN segment which opens the connection. - - The tcp_connect() function returns immediately; it does not wait for - the connection to be properly setup. Instead, it will call the - function specified as the fourth argument (the "connected" argument) - when the connection is established. If the connection could not be - properly established, either because the other host refused the - connection or because the other host didn't answer, the "err" - callback function of this pcb (registered with tcp_err, see below) - will be called. - - The tcp_connect() function can return ERR_MEM if no memory is - available for enqueueing the SYN segment. If the SYN indeed was - enqueued successfully, the tcp_connect() function returns ERR_OK. - - ---- Sending TCP data - -TCP data is sent by enqueueing the data with a call to -tcp_write(). When the data is successfully transmitted to the remote -host, the application will be notified with a call to a specified -callback function. - -- err_t tcp_write(struct tcp_pcb *pcb, const void *dataptr, u16_t len, - u8_t apiflags) - - Enqueues the data pointed to by the argument dataptr. The length of - the data is passed as the len parameter. The apiflags can be one or more of: - - TCP_WRITE_FLAG_COPY: indicates whether the new memory should be allocated - for the data to be copied into. If this flag is not given, no new memory - should be allocated and the data should only be referenced by pointer. This - also means that the memory behind dataptr must not change until the data is - ACKed by the remote host - - TCP_WRITE_FLAG_MORE: indicates that more data follows. If this is omitted, - the PSH flag is set in the last segment created by this call to tcp_write. - If this flag is given, the PSH flag is not set. - - The tcp_write() function will fail and return ERR_MEM if the length - of the data exceeds the current send buffer size or if the length of - the queue of outgoing segment is larger than the upper limit defined - in lwipopts.h. The number of bytes available in the output queue can - be retrieved with the tcp_sndbuf() function. - - The proper way to use this function is to call the function with at - most tcp_sndbuf() bytes of data. If the function returns ERR_MEM, - the application should wait until some of the currently enqueued - data has been successfully received by the other host and try again. - -- void tcp_sent(struct tcp_pcb *pcb, - err_t (* sent)(void *arg, struct tcp_pcb *tpcb, - u16_t len)) - - Specifies the callback function that should be called when data has - successfully been received (i.e., acknowledged) by the remote - host. The len argument passed to the callback function gives the - amount bytes that was acknowledged by the last acknowledgment. - - ---- Receiving TCP data - -TCP data reception is callback based - an application specified -callback function is called when new data arrives. When the -application has taken the data, it has to call the tcp_recved() -function to indicate that TCP can advertise increase the receive -window. - -- void tcp_recv(struct tcp_pcb *pcb, - err_t (* recv)(void *arg, struct tcp_pcb *tpcb, - struct pbuf *p, err_t err)) - - Sets the callback function that will be called when new data - arrives. The callback function will be passed a NULL pbuf to - indicate that the remote host has closed the connection. If - there are no errors and the callback function is to return - ERR_OK, then it must free the pbuf. Otherwise, it must not - free the pbuf so that lwIP core code can store it. - -- void tcp_recved(struct tcp_pcb *pcb, u16_t len) - - Must be called when the application has received the data. The len - argument indicates the length of the received data. - - ---- Application polling - -When a connection is idle (i.e., no data is either transmitted or -received), lwIP will repeatedly poll the application by calling a -specified callback function. This can be used either as a watchdog -timer for killing connections that have stayed idle for too long, or -as a method of waiting for memory to become available. For instance, -if a call to tcp_write() has failed because memory wasn't available, -the application may use the polling functionality to call tcp_write() -again when the connection has been idle for a while. - -- void tcp_poll(struct tcp_pcb *pcb, - err_t (* poll)(void *arg, struct tcp_pcb *tpcb), - u8_t interval) - - Specifies the polling interval and the callback function that should - be called to poll the application. The interval is specified in - number of TCP coarse grained timer shots, which typically occurs - twice a second. An interval of 10 means that the application would - be polled every 5 seconds. - - ---- Closing and aborting connections - -- err_t tcp_close(struct tcp_pcb *pcb) - - Closes the connection. The function may return ERR_MEM if no memory - was available for closing the connection. If so, the application - should wait and try again either by using the acknowledgment - callback or the polling functionality. If the close succeeds, the - function returns ERR_OK. - - The pcb is deallocated by the TCP code after a call to tcp_close(). - -- void tcp_abort(struct tcp_pcb *pcb) - - Aborts the connection by sending a RST (reset) segment to the remote - host. The pcb is deallocated. This function never fails. - - ATTENTION: When calling this from one of the TCP callbacks, make - sure you always return ERR_ABRT (and never return ERR_ABRT otherwise - or you will risk accessing deallocated memory or memory leaks! - - -If a connection is aborted because of an error, the application is -alerted of this event by the err callback. Errors that might abort a -connection are when there is a shortage of memory. The callback -function to be called is set using the tcp_err() function. - -- void tcp_err(struct tcp_pcb *pcb, void (* err)(void *arg, - err_t err)) - - The error callback function does not get the pcb passed to it as a - parameter since the pcb may already have been deallocated. - - ---- UDP interface - -The UDP interface is similar to that of TCP, but due to the lower -level of complexity of UDP, the interface is significantly simpler. - -- struct udp_pcb *udp_new(void) - - Creates a new UDP pcb which can be used for UDP communication. The - pcb is not active until it has either been bound to a local address - or connected to a remote address. - -- void udp_remove(struct udp_pcb *pcb) - - Removes and deallocates the pcb. - -- err_t udp_bind(struct udp_pcb *pcb, ip_addr_t *ipaddr, - u16_t port) - - Binds the pcb to a local address. The IP-address argument "ipaddr" - can be IP_ADDR_ANY to indicate that it should listen to any local IP - address. The function currently always return ERR_OK. - -- err_t udp_connect(struct udp_pcb *pcb, ip_addr_t *ipaddr, - u16_t port) - - Sets the remote end of the pcb. This function does not generate any - network traffic, but only set the remote address of the pcb. - -- err_t udp_disconnect(struct udp_pcb *pcb) - - Remove the remote end of the pcb. This function does not generate - any network traffic, but only removes the remote address of the pcb. - -- err_t udp_send(struct udp_pcb *pcb, struct pbuf *p) - - Sends the pbuf p. The pbuf is not deallocated. - -- void udp_recv(struct udp_pcb *pcb, - void (* recv)(void *arg, struct udp_pcb *upcb, - struct pbuf *p, - ip_addr_t *addr, - u16_t port), - void *recv_arg) - - Specifies a callback function that should be called when a UDP - datagram is received. - - ---- System initalization - -A truly complete and generic sequence for initializing the lwIP stack -cannot be given because it depends on additional initializations for -your runtime environment (e.g. timers). - -We can give you some idea on how to proceed when using the raw API. -We assume a configuration using a single Ethernet netif and the -UDP and TCP transport layers, IPv4 and the DHCP client. - -Call these functions in the order of appearance: - -- lwip_init() - - Initialize the lwIP stack and all of its subsystems. - -- netif_add(struct netif *netif, const ip4_addr_t *ipaddr, - const ip4_addr_t *netmask, const ip4_addr_t *gw, - void *state, netif_init_fn init, netif_input_fn input) - - Adds your network interface to the netif_list. Allocate a struct - netif and pass a pointer to this structure as the first argument. - Give pointers to cleared ip_addr structures when using DHCP, - or fill them with sane numbers otherwise. The state pointer may be NULL. - - The init function pointer must point to a initialization function for - your Ethernet netif interface. The following code illustrates its use. - - err_t netif_if_init(struct netif *netif) - { - u8_t i; - - for (i = 0; i < ETHARP_HWADDR_LEN; i++) { - netif->hwaddr[i] = some_eth_addr[i]; - } - init_my_eth_device(); - return ERR_OK; - } - - For Ethernet drivers, the input function pointer must point to the lwIP - function ethernet_input() declared in "netif/etharp.h". Other drivers - must use ip_input() declared in "lwip/ip.h". - -- netif_set_default(struct netif *netif) - - Registers the default network interface. - -- netif_set_link_up(struct netif *netif) - - This is the hardware link state; e.g. whether cable is plugged for wired - Ethernet interface. This function must be called even if you don't know - the current state. Having link up and link down events is optional but - DHCP and IPv6 discover benefit well from those events. - -- netif_set_up(struct netif *netif) - - This is the administrative (= software) state of the netif, when the - netif is fully configured this function must be called. - -- dhcp_start(struct netif *netif) - - Creates a new DHCP client for this interface on the first call. - - You can peek in the netif->dhcp struct for the actual DHCP status. - -- sys_check_timeouts() - - When the system is running, you have to periodically call - sys_check_timeouts() which will handle all timers for all protocols in - the stack; add this to your main loop or equivalent. - - ---- Optimalization hints - -The first thing you want to optimize is the lwip_standard_checksum() -routine from src/core/inet.c. You can override this standard -function with the #define LWIP_CHKSUM . - -There are C examples given in inet.c or you might want to -craft an assembly function for this. RFC1071 is a good -introduction to this subject. - -Other significant improvements can be made by supplying -assembly or inline replacements for htons() and htonl() -if you're using a little-endian architecture. -#define LWIP_PLATFORM_BYTESWAP 1 -#define LWIP_PLATFORM_HTONS(x) -#define LWIP_PLATFORM_HTONL(x) - -Check your network interface driver if it reads at -a higher speed than the maximum wire-speed. If the -hardware isn't serviced frequently and fast enough -buffer overflows are likely to occur. - -E.g. when using the cs8900 driver, call cs8900if_service(ethif) -as frequently as possible. When using an RTOS let the cs8900 interrupt -wake a high priority task that services your driver using a binary -semaphore or event flag. Some drivers might allow additional tuning -to match your application and network. - -For a production release it is recommended to set LWIP_STATS to 0. -Note that speed performance isn't influenced much by simply setting -high values to the memory options. - -For more optimization hints take a look at the lwIP wiki. - ---- Zero-copy MACs - -To achieve zero-copy on transmit, the data passed to the raw API must -remain unchanged until sent. Because the send- (or write-)functions return -when the packets have been enqueued for sending, data must be kept stable -after that, too. - -This implies that PBUF_RAM/PBUF_POOL pbufs passed to raw-API send functions -must *not* be reused by the application unless their ref-count is 1. - -For no-copy pbufs (PBUF_ROM/PBUF_REF), data must be kept unchanged, too, -but the stack/driver will/must copy PBUF_REF'ed data when enqueueing, while -PBUF_ROM-pbufs are just enqueued (as ROM-data is expected to never change). - -Also, data passed to tcp_write without the copy-flag must not be changed! - -Therefore, be careful which type of PBUF you use and if you copy TCP data -or not! diff --git a/ext/lwip/doc/savannah.txt b/ext/lwip/doc/savannah.txt deleted file mode 100644 index d7d19eb..0000000 --- a/ext/lwip/doc/savannah.txt +++ /dev/null @@ -1,120 +0,0 @@ -Daily Use Guide for using Savannah for lwIP - -Table of Contents: - -1 - Obtaining lwIP from the Git repository -2 - Committers/developers Git access using SSH -3 - Merging a development branch to master branch -4 - How to release lwIP - - - -1 Obtaining lwIP from the Git repository ----------------------------------------- - -To perform an anonymous Git clone of the master branch (this is where -bug fixes and incremental enhancements occur), do this: - git clone git://git.savannah.nongnu.org/lwip.git - -Or, obtain a stable branch (updated with bug fixes only) as follows: - git clone --branch DEVEL-1_4_1 git://git.savannah.nongnu.org/lwip.git - -Or, obtain a specific (fixed) release as follows: - git clone --branch STABLE-1_4_1 git://git.savannah.nongnu.org/lwip.git - - -2 Committers/developers Git access using SSH --------------------------------------------- - -The Savannah server uses SSH (Secure Shell) protocol 2 authentication and encryption. -As such, Git commits to the server occur through a SSH tunnel for project members. -To create a SSH2 key pair in UNIX-like environments, do this: - ssh-keygen -t dsa - -Under Windows, a recommended SSH client is "PuTTY", freely available with good -documentation and a graphic user interface.

The -general idea is that porting lwIP to new architectures requires only -small changes to a few header files and a new sys_arch -implementation. It is also possible to do a sys_arch implementation -that does not rely on any underlying operating system. - -The sys_arch provides semaphores and mailboxes to lwIP. For the full -lwIP functionality, multiple threads support can be implemented in the -sys_arch, but this is not required for the basic lwIP -functionality. Previous versions of lwIP required the sys_arch to -implement timer scheduling as well but as of lwIP 0.5 this is -implemented in a higher layer. - -In addition to the source file providing the functionality of sys_arch, -the OS emulation layer must provide several header files defining -macros used throughout lwip. The files required and the macros they -must define are listed below the sys_arch description. - -Semaphores can be either counting or binary - lwIP works with both -kinds. Mailboxes are used for message passing and can be implemented -either as a queue which allows multiple messages to be posted to a -mailbox, or as a rendez-vous point where only one message can be -posted at a time. lwIP works with both kinds, but the former type will -be more efficient. A message in a mailbox is just a pointer, nothing -more. - -Semaphores are represented by the type "sys_sem_t" which is typedef'd -in the sys_arch.h file. Mailboxes are equivalently represented by the -type "sys_mbox_t". lwIP does not place any restrictions on how -sys_sem_t or sys_mbox_t are represented internally. - -Since lwIP 1.4.0, semaphore and mailbox functions are prototyped in a way that -allows both using pointers or actual OS structures to be used. This way, memory -required for such types can be either allocated in place (globally or on the -stack) or on the heap (allocated internally in the "*_new()" functions). - -The following functions must be implemented by the sys_arch: - -- void sys_init(void) - - Is called to initialize the sys_arch layer. - -- err_t sys_sem_new(sys_sem_t *sem, u8_t count) - - Creates a new semaphore. The semaphore is allocated to the memory that 'sem' - points to (which can be both a pointer or the actual OS structure). - The "count" argument specifies the initial state of the semaphore (which is - either 0 or 1). - If the semaphore has been created, ERR_OK should be returned. Returning any - other error will provide a hint what went wrong, but except for assertions, - no real error handling is implemented. - -- void sys_sem_free(sys_sem_t *sem) - - Deallocates a semaphore. - -- void sys_sem_signal(sys_sem_t *sem) - - Signals a semaphore. - -- u32_t sys_arch_sem_wait(sys_sem_t *sem, u32_t timeout) - - Blocks the thread while waiting for the semaphore to be - signaled. If the "timeout" argument is non-zero, the thread should - only be blocked for the specified time (measured in - milliseconds). If the "timeout" argument is zero, the thread should be - blocked until the semaphore is signalled. - - If the timeout argument is non-zero, the return value is the number of - milliseconds spent waiting for the semaphore to be signaled. If the - semaphore wasn't signaled within the specified time, the return value is - SYS_ARCH_TIMEOUT. If the thread didn't have to wait for the semaphore - (i.e., it was already signaled), the function may return zero. - - Notice that lwIP implements a function with a similar name, - sys_sem_wait(), that uses the sys_arch_sem_wait() function. - -- int sys_sem_valid(sys_sem_t *sem) - - Returns 1 if the semaphore is valid, 0 if it is not valid. - When using pointers, a simple way is to check the pointer for != NULL. - When directly using OS structures, implementing this may be more complex. - This may also be a define, in which case the function is not prototyped. - -- void sys_sem_set_invalid(sys_sem_t *sem) - - Invalidate a semaphore so that sys_sem_valid() returns 0. - ATTENTION: This does NOT mean that the semaphore shall be deallocated: - sys_sem_free() is always called before calling this function! - This may also be a define, in which case the function is not prototyped. - -- err_t sys_mbox_new(sys_mbox_t *mbox, int size) - - Creates an empty mailbox for maximum "size" elements. Elements stored - in mailboxes are pointers. You have to define macros "_MBOX_SIZE" - in your lwipopts.h, or ignore this parameter in your implementation - and use a default size. - If the mailbox has been created, ERR_OK should be returned. Returning any - other error will provide a hint what went wrong, but except for assertions, - no real error handling is implemented. - -- void sys_mbox_free(sys_mbox_t *mbox) - - Deallocates a mailbox. If there are messages still present in the - mailbox when the mailbox is deallocated, it is an indication of a - programming error in lwIP and the developer should be notified. - -- void sys_mbox_post(sys_mbox_t *mbox, void *msg) - - Posts the "msg" to the mailbox. This function have to block until - the "msg" is really posted. - -- err_t sys_mbox_trypost(sys_mbox_t *mbox, void *msg) - - Try to post the "msg" to the mailbox. Returns ERR_MEM if this one - is full, else, ERR_OK if the "msg" is posted. - -- u32_t sys_arch_mbox_fetch(sys_mbox_t *mbox, void **msg, u32_t timeout) - - Blocks the thread until a message arrives in the mailbox, but does - not block the thread longer than "timeout" milliseconds (similar to - the sys_arch_sem_wait() function). If "timeout" is 0, the thread should - be blocked until a message arrives. The "msg" argument is a result - parameter that is set by the function (i.e., by doing "*msg = - ptr"). The "msg" parameter maybe NULL to indicate that the message - should be dropped. - - The return values are the same as for the sys_arch_sem_wait() function: - Number of milliseconds spent waiting or SYS_ARCH_TIMEOUT if there was a - timeout. - - Note that a function with a similar name, sys_mbox_fetch(), is - implemented by lwIP. - -- u32_t sys_arch_mbox_tryfetch(sys_mbox_t *mbox, void **msg) - - This is similar to sys_arch_mbox_fetch, however if a message is not - present in the mailbox, it immediately returns with the code - SYS_MBOX_EMPTY. On success 0 is returned. - - To allow for efficient implementations, this can be defined as a - function-like macro in sys_arch.h instead of a normal function. For - example, a naive implementation could be: - #define sys_arch_mbox_tryfetch(mbox,msg) \ - sys_arch_mbox_fetch(mbox,msg,1) - although this would introduce unnecessary delays. - -- int sys_mbox_valid(sys_mbox_t *mbox) - - Returns 1 if the mailbox is valid, 0 if it is not valid. - When using pointers, a simple way is to check the pointer for != NULL. - When directly using OS structures, implementing this may be more complex. - This may also be a define, in which case the function is not prototyped. - -- void sys_mbox_set_invalid(sys_mbox_t *mbox) - - Invalidate a mailbox so that sys_mbox_valid() returns 0. - ATTENTION: This does NOT mean that the mailbox shall be deallocated: - sys_mbox_free() is always called before calling this function! - This may also be a define, in which case the function is not prototyped. - -If threads are supported by the underlying operating system and if -such functionality is needed in lwIP, the following function will have -to be implemented as well: - -- sys_thread_t sys_thread_new(char *name, void (* thread)(void *arg), void *arg, int stacksize, int prio) - - Starts a new thread named "name" with priority "prio" that will begin its - execution in the function "thread()". The "arg" argument will be passed as an - argument to the thread() function. The stack size to used for this thread is - the "stacksize" parameter. The id of the new thread is returned. Both the id - and the priority are system dependent. - -- sys_prot_t sys_arch_protect(void) - - This optional function does a "fast" critical region protection and returns - the previous protection level. This function is only called during very short - critical regions. An embedded system which supports ISR-based drivers might - want to implement this function by disabling interrupts. Task-based systems - might want to implement this by using a mutex or disabling tasking. This - function should support recursive calls from the same task or interrupt. In - other words, sys_arch_protect() could be called while already protected. In - that case the return value indicates that it is already protected. - - sys_arch_protect() is only required if your port is supporting an operating - system. - -- void sys_arch_unprotect(sys_prot_t pval) - - This optional function does a "fast" set of critical region protection to the - value specified by pval. See the documentation for sys_arch_protect() for - more information. This function is only required if your port is supporting - an operating system. - -For some configurations, you also need: - -- u32_t sys_now(void) - - This optional function returns the current time in milliseconds (don't care - for wraparound, this is only used for time diffs). - Not implementing this function means you cannot use some modules (e.g. TCP - timestamps, internal timeouts for NO_SYS==1). - - -Note: - -Be carefull with using mem_malloc() in sys_arch. When malloc() refers to -mem_malloc() you can run into a circular function call problem. In mem.c -mem_init() tries to allcate a semaphore using mem_malloc, which of course -can't be performed when sys_arch uses mem_malloc. - -------------------------------------------------------------------------------- -Additional files required for the "OS support" emulation layer: -------------------------------------------------------------------------------- - -cc.h - Architecture environment, some compiler specific, some - environment specific (probably should move env stuff - to sys_arch.h.) - - Typedefs for the types used by lwip - - u8_t, s8_t, u16_t, s16_t, u32_t, s32_t, mem_ptr_t - - Compiler hints for packing lwip's structures - - PACK_STRUCT_FIELD(x) - PACK_STRUCT_STRUCT - PACK_STRUCT_BEGIN - PACK_STRUCT_END - - Platform specific diagnostic output - - LWIP_PLATFORM_DIAG(x) - non-fatal, print a message. - LWIP_PLATFORM_ASSERT(x) - fatal, print message and abandon execution. - Portability defines for printf formatters: - U16_F, S16_F, X16_F, U32_F, S32_F, X32_F, SZT_F - - "lightweight" synchronization mechanisms - - SYS_ARCH_DECL_PROTECT(x) - declare a protection state variable. - SYS_ARCH_PROTECT(x) - enter protection mode. - SYS_ARCH_UNPROTECT(x) - leave protection mode. - - If the compiler does not provide memset() this file must include a - definition of it, or include a file which defines it. - - This file must either include a system-local which defines - the standard *nix error codes, or it should #define LWIP_PROVIDE_ERRNO - to make lwip/arch.h define the codes which are used throughout. - - -perf.h - Architecture specific performance measurement. - Measurement calls made throughout lwip, these can be defined to nothing. - PERF_START - start measuring something. - PERF_STOP(x) - stop measuring something, and record the result. - -sys_arch.h - Tied to sys_arch.c - - Arch dependent types for the following objects: - sys_sem_t, sys_mbox_t, sys_thread_t, - And, optionally: - sys_prot_t - - Defines to set vars of sys_mbox_t and sys_sem_t to NULL. - SYS_MBOX_NULL NULL - SYS_SEM_NULL NULL diff --git a/ext/lwip/src/FILES b/ext/lwip/src/FILES deleted file mode 100644 index 952aeab..0000000 --- a/ext/lwip/src/FILES +++ /dev/null @@ -1,13 +0,0 @@ -api/ - The code for the high-level wrapper API.

lwIP - A Lightweight TCP/IP Stack

-

- The web page you are watching was served by a simple web - server running on top of the lightweight TCP/IP stack lwIP. -

-

- lwIP is an open source implementation of the TCP/IP - protocol suite that was originally written by Adam Dunkels - of the Swedish Institute of Computer Science but now is - being actively developed by a team of developers - distributed world-wide. Since it's release, lwIP has - spurred a lot of interest and has been ported to several - platforms and operating systems. lwIP can be used either - with or without an underlying OS. -

-

- The focus of the lwIP TCP/IP implementation is to reduce - the RAM usage while still having a full scale TCP. This - makes lwIP suitable for use in embedded systems with tens - of kilobytes of free RAM and room for around 40 kilobytes - of code ROM. -

-

- More information about lwIP can be found at the lwIP - homepage at http://savannah.nongnu.org/projects/lwip/ - or at the lwIP wiki at http://lwip.wikia.com/. -

By defining LWIP_HTTPD_DYNAMIC_HEADERS in - * lwipopts.h, this behavior can be changed such that the server inserts the - * headers automatically based on the extension of the file being served. If - * this mode is used, be careful to ensure that the file system image used - * does not already contain the header information. - * - * File system images without headers can be created using the makefsfile - * tool with the -h command line option. - * - * - * Notes about valid SSI tags - * -------------------------- - * - * The following assumptions are made about tags used in SSI markers: - * - * 1. No tag may contain '-' or whitespace characters within the tag name. - * 2. Whitespace is allowed between the tag leadin "". - * 3. The maximum tag name length is LWIP_HTTPD_MAX_TAG_NAME_LEN, currently 8 characters. - * - * Notes on CGI usage - * ------------------ - * - * The simple CGI support offered here works with GET method requests only - * and can handle up to 16 parameters encoded into the URI. The handler - * function may not write directly to the HTTP output but must return a - * filename that the HTTP server will send to the browser as a response to - * the incoming CGI request. - * - * - * - * The list of supported file types is quite short, so if makefsdata complains - * about an unknown extension, make sure to add it (and its doctype) to - * the 'g_psHTTPHeaders' list. - */ -#include "lwip/init.h" -#include "lwip/apps/httpd.h" -#include "lwip/debug.h" -#include "lwip/stats.h" -#include "lwip/apps/fs.h" -#include "httpd_structs.h" -#include "lwip/def.h" -#include "lwip/ip.h" -#include "lwip/tcp.h" - -#include -#include -#include - -#if LWIP_TCP - -/** Minimum length for a valid HTTP/0.9 request: "GET /\r\n" -> 7 bytes */ -#define MIN_REQ_LEN 7 - -#define CRLF "\r\n" -#if LWIP_HTTPD_SUPPORT_11_KEEPALIVE -#define HTTP11_CONNECTIONKEEPALIVE "Connection: keep-alive" -#define HTTP11_CONNECTIONKEEPALIVE2 "Connection: Keep-Alive" -#endif - -/** These defines check whether tcp_write has to copy data or not */ - -/** This was TI's check whether to let TCP copy data or not - * \#define HTTP_IS_DATA_VOLATILE(hs) ((hs->file < (char *)0x20000000) ? 0 : TCP_WRITE_FLAG_COPY) - */ -#ifndef HTTP_IS_DATA_VOLATILE -#if LWIP_HTTPD_SSI -/* Copy for SSI files, no copy for non-SSI files */ -#define HTTP_IS_DATA_VOLATILE(hs) ((hs)->ssi ?

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License along - with this program; if not, write to the Free Software Foundation, Inc., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

In this example we aim to set up a minimal [Android Studio](https://developer.android.com/studio/index.html) project which contains all of the components necessary to enable ZeroTier for your app. - -*NOTE: For Android JNI libraries to build you'll need to install [Android Studio](https://developer.android.com/studio/index.html) the [Android NDK](https://developer.android.com/ndk/index.html). Currently only Android NDK r10e is supported and can be found [here for OSX](http://dl.google.com/android/repository/android-ndk-r10e-darwin-x86_64.zip) and [here for Linux](http://dl.google.com/android/repository/android-ndk-r10e-linux-x86_64.zip). You'll need to tell our project where you put it by putting the path in [this file](android_jni_lib/proj/local.properties), you'll need to install the Android Build-Tools (this can typically be done through the editor the first time you start it up), and finally you should probably upgrade your Gradle plugin if it asks you to. If you don't have these things installed and configured we will detect that and just skip those builds automatically.* - -If you want to skip the following steps and just take a look at the project, go [here](example_app). - -*** - -**Step 1: App Code Modifications** - - In your project, create a new package called `ZeroTier` and class file within called `ZTSDK.java` and copy contents from `src/wrappers/java/JavaWrapper.java` - - - Start the service - - ``` - String nwid = "8056c2e21c000001"; - // Set up service - final ZTSDK zt = new ZTSDK(); - final String homeDir = getApplicationContext().getFilesDir() + "/zerotier"; - new Thread(new Runnable() { - public void run() { - // Calls to JNI code - zt.start_service(homeDir); - } - }).start(); - while(!zt.running()) { } - ``` - - - Join network and start doing network stuff! - - ``` - zt.join_network(nwid); - int sock = zt.socket(zt.AF_INET, zt.SOCK_STREAM, 0); - int err = zt.connect(sock, "10.9.9.203", 8080, nwid); - // zt.recvfrom(), zt.write(), etc... - ``` - -**Step 2: App permissions** - - - In order for your application to write the auth keys and network files to the internal storage you'll need to set a few permissions in your `AndroidManifest.xml` file at the same scope level as ``: - - ``` - - - ``` - -**Step 3: Set NDK/SDK paths** - - Specify your SDK/NDK path in `android_jni_lib/proj/local.properties`. For example: - - ``` - sdk.dir=/Users/Name/Library/Android/sdk - ndk.dir=/Users/Name/Library/Android/ndk-r10e - ``` - -**Step 4: Select build targets** - - Specify the target architectures you want to build in [Application.mk](android_jni_lib/java/jni/Application.mk). By default it will build `arm64-v8a`, `armeabi`, `armeabi-v7a`, `mips`, `mips64`, `x86`, and `x86_64`. For each architecture you wish to support a different shared library will need to be built. This is all taken care of automatically by the build script. - -**Step 4: Build Shared Library** - - `make android_jni_lib` - - The resultant `build/android_jni_lib/ARCH/libZeroTierOneJNI.so` is what you want to import into your own project to provide our API implementation to your app. Select your architecture and copy the shared library `libZeroTierOneJNI.so` into your project's JNI directory, possibly `/src/main/jniLibs/ARCH/libZeroTierOneJNI.so`. - - Selecting only the architectures you need will *significantly* reduce overall build time. diff --git

Just install `zerotier-sdk-service`, `libztintercept.so`, and `liblwip.so` into the container at an appropriate locations. We suggest putting it all in `/var/lib/zerotier-one` since this is the default ZeroTier home and will eliminate the need to supply a path to any of ZeroTier's services or utilities. Then, in your Docker container entry point script launch the service with *-d* to run it in the background, set the appropriate environment variables as described above, and launch your container's main application. - -The only bit of complexity is configuring which virtual network to join. ZeroTier's service automatically joins networks that have `.conf` files in `ZTHOME/networks.d` even if the `.conf` file is empty. So one way of doing this very easily is to add the following commands to your Dockerfile or container entry point script: - - mkdir -p /var/lib/zerotier-one/networks.d - touch /var/lib/zerotier-one/networks.d/8056c2e21c000001.conf - -Replace 8056c2e21c000001 with the network ID of the network you want your container to automatically join. It's also a good idea in your container's entry point script to add a small loop to wait until the container's instance of ZeroTier generates an identity and comes online. This could be something like: - - /var/lib/zerotier-one/zerotier-sdk-service -d - while [ ! -f /var/lib/zerotier-one/identity.secret ]; do - sleep 0.1 - done - # zerotier-sdk-service is now running and has generated an identity - -(Be sure you don't bundle the identity into the container, otherwise every container will try to be the same device and they will "fight" over the device's address.) - -Now each new instance of your container will automatically join the specified network on startup. Authorizing the container on a private network still requires a manual authorization step either via the ZeroTier Central web UI or the API. We're working on some ideas to automate this via bearer token auth or similar since doing this manually or with scripts for large deployments is tedious. diff --git a/integrations/docker/_remove_all.sh b/integrations/docker/_remove_all.sh deleted file mode 100755 index c6090a9..0000000 --- a/integrations/docker/_remove_all.sh +++ /dev/null @@ -1,5 +0,0 @@ -#!/bin/bash -# Delete all containers -docker rm $(docker ps -a -q) -# Delete all images -docker rmi $(docker images -q) diff --git a/integrations/docker/docker_demo/README.md b/integrations/docker/docker_demo/README.md deleted file mode 100644 index 10b25f8..0000000 --- a/integrations/docker/docker_demo/README.md +++ /dev/null @@ -1,7 +0,0 @@ -Simple Docker Demo -==== - -- Type `make docker_demo` to build an image with the SDK pre-installed and a test image to serve as a monitor -- From this local directory, start both containers with `./start.sh` - -Results of the test can be found in `_results` \ No newline at end of file diff --git a/integrations/docker/docker_demo/docker_demo.name b/integrations/docker/docker_demo/docker_demo.name deleted file mode 100644 index e69de29..0000000 diff --git a/integrations/docker/docker_demo/hello.lua b/integrations/docker/docker_demo/hello.lua deleted file mode 100644 index 59a2dea..0000000 --- a/integrations/docker/docker_demo/hello.lua +++ /dev/null @@ -1,3 +0,0 @@ -local msg = "welcome to the machine!" -redis.call("SET", "msg", msg) -return redis.call("GET", "msg") diff --git a/integrations/docker/docker_demo/monitor_dockerfile b/integrations/docker/docker_demo/monitor_dockerfile deleted file mode 100644 index 3c89941..0000000 --- a/integrations/docker/docker_demo/monitor_dockerfile +++ /dev/null @@ -1,28 +0,0 @@ -# ZT SDK Test Monitor -FROM fedora:23 -MAINTAINER https://www.zerotier.com/ - -RUN yum -y install redis-3.0.4-1.fc23.x86_64 - -EXPOSE 9993/udp - -# Add ZT files -RUN mkdir -p /var/lib/zerotier-one/networks.d -ADD monitor_identity.public /var/lib/zerotier-one/identity.public -ADD monitor_identity.secret /var/lib/zerotier-one/identity.secret -ADD *.conf /var/lib/zerotier-one/networks.d/ -ADD *.conf / -ADD *.name / - -# Install LWIP library used by service -ADD liblwip.so /var/lib/zerotier-one/liblwip.so - -ADD hello.lua / - -ADD zerotier-one / -ADD zerotier-cli / - -# Start ZeroTier-One -ADD monitor_entrypoint.sh /monitor_entrypoint.sh -RUN chmod -v +x /monitor_entrypoint.sh -CMD ["./monitor_entrypoint.sh"] diff --git a/integrations/docker/docker_demo/monitor_entrypoint.sh b/integrations/docker/docker_demo/monitor_entrypoint.sh deleted file mode 100644 index 384a226..0000000 --- a/integrations/docker/docker_demo/monitor_entrypoint.sh +++ /dev/null @@ -1,50 +0,0 @@ -#!/bin/bash - -export PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/ - -# --- Test Parameters --- -test_namefile=$(ls *.name) -test_name="${test_namefile%.*}" # test network id -nwconf=$(ls *.conf) # blank test network config file -nwid="${nwconf%.*}" # test network id -sdk_wait_time=60 # wait for test container to come online -app_timeout_time=15 # app-specific timeout -file_path=/opt/results/ # test result output file path (fs shared between host and containers) -file_base="$test_name".txt # test result output file -fail=FAIL. # appended to result file in event of failure -ok=OK. # appended to result file in event of success -tmp_ext=.tmp # temporary filetype used for sharing test data between containers -address_file="$file_path$test_name"_addr"$tmp_ext" # file shared between host and containers for sharing address (optional) - -# --- Network Config --- -echo '*** ZeroTier SDK Test Monitor' -chown -R daemon /var/lib/zerotier-one -chgrp -R daemon /var/lib/zerotier-one -su daemon -s /bin/bash -c '/zerotier-one -d -U -p9993 >>/tmp/zerotier-one.out 2>&1' -virtip4="" -while [ -z "$virtip4" ];

Names will be altered during copy step so the dockerfiles know which identities to use for each image/container: - - cp /tmp/sdk_first/identity.public ./sdk/tests/docker/sdk_identity.public - cp /tmp/sdk_first/identity.secret ./sdk/tests/docker/sdk_identity.secret - - cp /tmp/sdk_second/identity.public ./sdk/tests/docker/monitor_identity.public - cp /tmp/sdk_second/identity.secret ./sdk/tests/docker/monitor_identity.secret - - -5) Place a blank network config file in the `tests/docker` directory (e.g. "8056c2e21c000001.conf") - - This will be used to inform test-specific scripts what network to use for testing - -After you've created your network and placed its blank config file in `tests/docker` run the following to perform unit tests for httpd: - - ./build.sh httpd - ./test.sh httpd - -It's useful to note that the keyword *httpd* in this example is merely a substring for a test name, this means that if we replaced it with *x86_64*, *fc23*, or *nginx*, it would run all unit tests for *x86_64*, *Fedora 23*, or *nginx* respectively. - diff --git a/tests/api_test/clients.sh b/tests/api_test/clients.sh deleted file mode 100755 index 3e7497d..0000000 --- a/tests/api_test/clients.sh +++ /dev/null @@ -1,46 +0,0 @@ -#!/bin/bash - -echo "\n\n\n\nStarting client(s)" - -# test.sh [udp|tcp|all] [nwid] -TEST_EXECUTABLE_PATH="build/tests" -protocol=$1 -NWID=$2 -HOME_DIR=$(pwd)/$TEST_EXECUTABLE_PATH -ZT_HOME_PATH=$(pwd)/$TEST_EXECUTABLE_PATH/zerotier - -BUILD_PATH=$(pwd)/build -localAddr="127.0.0.1" - -export ZT_NC_NETWORK=$ZT_HOME_PATH/nc_$NWID -export DYLD_LIBRARY_PATH=.$HOME_DIR/libztintercept.so - -echo "network = " $NWID -echo "protocol = " $protocol -echo "ZT_NC_NETWORK = " $ZT_NC_NETWORK -echo "ZT_NC_NETWORK = " $ZT_NC_NETWORK - -echo "ZT_HOME_PATH = " $ZT_HOME_PATH -echo "DYLD_LIBRARY_PATH = " $DYLD_LIBRARY_PATH - -# Start ZeroTier service -echo "Starting ZeroTier background service..." -mkdir -p $ZT_HOME_PATH/networks.d -touch $ZT_HOME_PATH/networks.d/$NWID.conf -$BUILD_PATH/zerotier-sdk-service -U -p$RANDOM $ZT_HOME_PATH & -zt_service_pid=$! - -if [ $protocol="tcp" ]; then - echo "Starting TCP test..." - random_tcp_server_port=$RANDOM - ./$TEST_EXECUTABLE_PATH/Darwin.tcp_server.out $random_tcp_server_port & - tcp_server_pid=$! - echo "TCP SERVER AT = " $localAddr ":" $random_tcp_server_port - sleep 3 - ./$TEST_EXECUTABLE_PATH/Darwin.tcp_client.out $localAddr $random_tcp_server_port & - tcp_client_pid=$! -fi - -echo "Waiting for test to conclude..." -sleep 5 -kill -9 $zt_service_PID $tcp_server_pid $tcp_client_pid diff --git a/tests/api_test/multiclient.c b/tests/api_test/multiclient.c deleted file mode 100644 index 4441bcb..0000000 --- a/tests/api_test/multiclient.c +++ /dev/null @@ -1,60 +0,0 @@ -// TCP Client test program - -#include -#include -#include -#include -#include - -int atoi(const char *str); -int close(int filedes); - -#define MSG_SZ 128 - -int main(int argc , char *argv[]) -{ - if(argc < 3) { - printf("usage: client \n"); - return 1; - } - - int sock, port = atoi(argv[2]); - struct sockaddr_in server; - char message[MSG_SZ] , server_reply[MSG_SZ]; - - sock = socket(AF_INET , SOCK_STREAM , 0); - if (sock == -1) { - printf("could not create socket"); - } - server.sin_addr.s_addr = inet_addr(argv[1]); - server.sin_family = AF_INET; - server.sin_port = htons( port ); - - printf("connecting...\n"); - if (connect(sock , (struct sockaddr *)&server , sizeof(server)) < 0) { - perror("connect failed.

This dynamically loads our intercept library into your application which allows us to re-direct its network calls to our virtual network. - -Tell the ZeroTier Network Containers service which network to connect to with `export ZT_NC_NETWORK=/var/lib/zerotier-one/nc_XXXXXXXXXXXXXXXX`. - -**Step 5: Run your new ZeroTier-enabled service** - -At this point, simply run your application as you normally would. It will be automatically intercepted and linked to the ZeroTier service (and hence your virtual networks!) - -`/usr/bin/redis-server --port 6379` - -*** -**Additional info** -If you'd like to know the IP address your service can be reached at on this particular virtual network, use the following: -`zerotier-cli -D/var/lib/zerotier-one/nc_XXXXXXXXXXXXXXXX listnetworks` - -## Installing in a Docker container (or any other container engine) - -If it's not immediately obvious, installation into a Docker container is easy. Just install `zerotier-sdk-service`, `libztintercept.so`, and `liblwip.so` into the container at an appropriate locations. We suggest putting it all in `/var/lib/zerotier-one` since this is the default ZeroTier home and will eliminate the need to supply a path to any of ZeroTier's services or utilities. Then, in your Docker container entry point script launch the service with *-d* to run it in the background, set the appropriate environment variables as described above, and launch your container's main application. - -The only bit of complexity is configuring which virtual network to join. ZeroTier's service automatically joins networks that have `.conf` files in `ZTHOME/networks.d` even if the `.conf` file is empty. So one way of doing this very easily is to add the following commands to your Dockerfile or container entry point script: - - mkdir -p /var/lib/zerotier-one/networks.d - touch /var/lib/zerotier-one/networks.d/8056c2e21c000001.conf - -Replace 8056c2e21c000001 with the network ID of the network you want your container to automatically join. It's also a good idea in your container's entry point script to add a small loop to wait until the container's instance of ZeroTier generates an identity and comes online. This could be something like: - - /var/lib/zerotier-one/zerotier-sdk-service -d - while [ ! -f /var/lib/zerotier-one/identity.secret ]; do - sleep 0.1 - done - # zerotier-sdk-service is now running and has generated an identity - -(Be sure you don't bundle the identity into the container, otherwise every container will try to be the same device and they will "fight" over the device's address.) - -Now each new instance of your container will automatically join the specified network on startup. Authorizing the container on a private network still requires a manual authorization step either via the ZeroTier Central web UI or the API. We're working on some ideas to automate this via bearer token auth or similar since doing this manually or with scripts for large deployments is tedious. diff --git a/tests/unit/_remove_all.sh b/tests/unit/_remove_all.sh deleted file mode 100755 index c6090a9..0000000 --- a/tests/unit/_remove_all.sh +++ /dev/null @@ -1,5 +0,0 @@ -#!/bin/bash -# Delete all containers -docker rm $(docker ps -a -q) -# Delete all images -docker rmi $(docker images -q) diff --git a/tests/unit/docker/565799d8f658068e.conf b/tests/unit/docker/565799d8f658068e.conf deleted file mode 100644 index e69de29..0000000 diff --git a/tests/unit/docker/README.md b/tests/unit/docker/README.md deleted file mode 100644 index 10b25f8..0000000 --- a/tests/unit/docker/README.md +++ /dev/null @@ -1,7 +0,0 @@ -Simple Docker Demo -==== - -- Type `make docker_demo` to build an image with the SDK pre-installed and a test image to serve as a monitor -- From this local directory, start both containers with `./start.sh` - -Results of the test can be found in `_results` \ No newline at end of file diff --git a/tests/unit/docker/docker_demo.name b/tests/unit/docker/docker_demo.name deleted file mode 100644 index e69de29..0000000 diff --git a/tests/unit/docker/hello.lua b/tests/unit/docker/hello.lua deleted file mode 100644 index 59a2dea..0000000 --- a/tests/unit/docker/hello.lua +++ /dev/null @@ -1,3 +0,0 @@ -local msg = "welcome to the machine!" -redis.call("SET", "msg", msg) -return redis.call("GET", "msg") diff --git a/tests/unit/docker/monitor_dockerfile b/tests/unit/docker/monitor_dockerfile deleted file mode 100644 index 3c89941..0000000 --- a/tests/unit/docker/monitor_dockerfile +++ /dev/null @@ -1,28 +0,0 @@ -# ZT SDK Test Monitor -FROM fedora:23 -MAINTAINER https://www.zerotier.com/ - -RUN yum -y install redis-3.0.4-1.fc23.x86_64 - -EXPOSE 9993/udp - -# Add ZT files -RUN mkdir -p /var/lib/zerotier-one/networks.d -ADD monitor_identity.public /var/lib/zerotier-one/identity.public -ADD monitor_identity.secret /var/lib/zerotier-one/identity.secret -ADD *.conf /var/lib/zerotier-one/networks.d/ -ADD *.conf / -ADD *.name / - -# Install LWIP library used by service -ADD liblwip.so /var/lib/zerotier-one/liblwip.so - -ADD hello.lua / - -ADD zerotier-one / -ADD zerotier-cli / - -# Start ZeroTier-One -ADD monitor_entrypoint.sh /monitor_entrypoint.sh -RUN chmod -v +x /monitor_entrypoint.sh -CMD ["./monitor_entrypoint.sh"] diff --git a/tests/unit/docker/monitor_entrypoint.sh b/tests/unit/docker/monitor_entrypoint.sh deleted file mode 100644 index 6b85ac2..0000000 --- a/tests/unit/docker/monitor_entrypoint.sh +++ /dev/null @@ -1,54 +0,0 @@ -#!/bin/bash - -export PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/ - -# --- Test Parameters --- -test_namefile=$(ls *.name) -test_name="${test_namefile%.*}" # test network id -nwconf=$(ls *.conf) # blank test network config file -nwid="${nwconf%.*}" # test network id -sdk_wait_time=60 # wait for test container to come online -app_timeout_time=15 # app-specific timeout -file_path=/opt/results/ # test result output file path (fs shared between host and containers) -file_base="$test_name".txt # test result output file -fail=FAIL. # appended to result file in event of failure -ok=OK. # appended to result file in event of success -tmp_ext=.tmp # temporary filetype used for sharing test data between containers -address_file="$file_path$test_name"_addr"$tmp_ext" # file shared between host and containers for sharing address (optional) - -# --- Network Config --- -echo '*** ZeroTier SDK Test Monitor' -chown -R daemon /var/lib/zerotier-one -chgrp -R daemon /var/lib/zerotier-one -su daemon -s /bin/bash -c '/zerotier-one -d -U -p9993 >>/tmp/zerotier-one.out 2>&1' -virtip4="" -while [ -z "$virtip4" ];

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License along - with this program; if not, write to the Free Software Foundation, Inc., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16.

Apps for Android and iOS are available for free in the Google Play and Apple app stores. - -### Getting Started - -ZeroTier's basic operation is easy to understand. Devices have 10-digit *ZeroTier addresses* like `89e92ceee5` and networks have 16-digit network IDs like `8056c2e21c000001`. All it takes for a device to join a network is its 16-digit ID, and all it takes for a network to authorize a device is its 10-digit address. Everything else is automatic. - -A "device" in our terminology is any "unit of compute" capable of talking to a network: desktops, laptops, phones, servers, VMs/VPSes, containers, and even user-space applications via our [SDK](https://github.com/zerotier/ZeroTierSDK). - -For testing purposes we provide a public virtual network called *Earth* with network ID `8056c2e21c000001`. You can join it with: - - sudo zerotier-cli join 8056c2e21c000001 - -Now wait about 30 seconds and check your system with `ip addr list` or `ifconfig`. You'll see a new interface whose name starts with *zt* and it should quickly get an IPv4 and an IPv6 address. Once you see it get an IP, try pinging `earth.zerotier.net` at `29.209.112.93`. If you've joined Earth from more than one system, try pinging your other machine. If you don't want to belong to a giant Ethernet party line anymore, just type: - - sudo zerotier-cli leave 8056c2e21c000001 - -The *zt* interface will disappear. You're no longer on the network. - -To create networks of your own, you'll need a network controller. ZeroTier One (for desktops and servers) includes controller functionality in its default build that can be configured via its JSON API (see [README.md in controller/](controller/)). ZeroTier provides a hosted solution with a nice web UI and SaaS add-ons at [my.zerotier.com](https://my.zerotier.com/). Basic controller functionality is free for up to 100 devices. - -### Project Layout - - - `artwork/`: icons, logos, etc. - - `attic/`: old stuff and experimental code that we want to keep around for reference. - - `controller/`: the reference network controller implementation, which is built and included by default on desktop and server build targets. - - `debian/`: files for building Debian packages on Linux. - - `doc/`: manual pages and other documentation. - - `ext/`: third party libraries, binaries that we ship for convenience on some platforms (Mac and Windows), and installation support files. - - `include/`: include files for the ZeroTier core. - - `java/`: a JNI wrapper used with our Android mobile app. (The whole Android app is not open source but may be made so in the future.) - - `macui/`: a Macintosh menu-bar app for controlling ZeroTier One, written in Objective C. - - `node/`: the ZeroTier virtual Ethernet switch core, which is designed to be entirely separate from the rest of the code and able to be built as a stand-alone OS-independent library. Note to developers: do not use C++11 features in here, since we want this to build on old embedded platforms that lack C++11 support. C++11 can be used elsewhere. - - `osdep/`: code to support and integrate with OSes, including platform-specific stuff only built for certain targets. - - `service/`: the ZeroTier One service, which wraps the ZeroTier core and provides VPN-like connectivity to virtual networks for desktops, laptops, servers, VMs, and containers. - - `tcp-proxy/`: TCP proxy code run by ZeroTier, Inc. to provide TCP fallback (this will die soon!). - - `windows/`: Visual Studio solution files, Windows service code for ZeroTier One, and the Windows task bar app UI. - -The base path contains the ZeroTier One service main entry point (`one.cpp`), self test code, makefiles, etc. - -### Build and Platform Notes - -To build on Mac and Linux just type `make`. On FreeBSD and OpenBSD `gmake` (GNU make) is required and can be installed from packages or ports. For Windows there is a Visual Studio solution in `windows/'. - - - **Mac** - - Xcode command line tools for OSX 10.7 or newer are required. - - Tap device driver kext source is in `ext/tap-mac` and a signed pre-built binary can be found in `ext/bin/tap-mac`. You should not need to build it yourself. It's a fork of [tuntaposx](http://tuntaposx.sourceforge.net) with device names changed to `zt#`, support for a larger MTU, and tun functionality removed. - - **Linux** - - The minimum compiler versions required are GCC/G++ 4.9.3 or CLANG/CLANG++ 3.4.2. - - Linux makefiles automatically detect and prefer clang/clang++ if present as it produces smaller and slightly faster binaries in most cases. You can override by supplying CC and CXX variables on the make command line. - - CentOS 7 ships with a version of GCC/G++ that is too old, but a new enough version of CLANG can be found in the *epel* repositories. Type `yum install epel-release` and then `yum install clang` to build there. - - **Windows** - - Windows 7 or newer (and equivalent server versions) are supported. This *may* work on Vista but you're on your own there. Windows XP is not supported since it lacks many important network API functions. - - We build with Visual Studio 2015. Older versions may not work with the solution file and project files we ship and may not have new enough C++11 support. - - Pre-built signed Windows drivers are included in `ext/bin/tap-windows-ndis6`. The MSI files found there will install them on 32-bit and 64-bit systems. (These are included in our multi-architecture installer as chained MSIs.) - - Windows builds are more painful in general than other platforms and are for the adventurous. - - **FreeBSD** - - Tested most recently on FreeBSD-11. Older versions may work but we're not sure. - - GCC/G++ 4.9 and gmake are required. These can be installed from packages or ports. Type `gmake` to build. - - **OpenBSD** - - There is a limit of four network memberships on OpenBSD as there are only four tap devices (`/dev/tap0` through `/dev/tap3`). We're not sure if this can be increased. - - OpenBSD lacks `getifmaddrs` (or any equivalent method) to get interface multicast memberships. As a result multicast will only work on OpenBSD for ARP and NDP (IP/MAC lookup) and not for other purposes. - - Only tested on OpenBSD 6.0. Older versions may not work. - - GCC/G++ 4.9 and gmake are required and can be installed using `pkg_add` or from ports. They get installed in `/usr/local/bin` as `egcc` and `eg++` and our makefile is pre-configured to use them on OpenBSD. - -Typing `make selftest` will build a *zerotier-selftest* binary which unit tests various internals and reports on a few aspects of the build environment. It's a good idea to try this on novel platforms or architectures. - -### Running - -Running *zerotier-one* with -h will show help. - -On Linux and BSD you can start the service with: - - sudo ./zerotier-one -d - -A home folder for your system will automatically be created. - -The service is controlled via the JSON API, which by default is available at 127.0.0.1 port 9993. We include a *zerotier-cli* command line utility to make API calls for standard things like joining and leaving networks. The *authtoken.secret* file in the home folder contains the secret token for accessing this API. See README.md in [service/](service/) for API documentation. - -Here's where home folders live (by default) on each OS: - - * **Linux**: `/var/lib/zerotier-one` - * **FreeBSD** / **OpenBSD**: `/var/db/zerotier-one` - * **Mac**: `/Library/Application Support/ZeroTier/One` - * **Windows**: `\ProgramData\ZeroTier\One` (That's for Windows 7. The base 'shared app data' folder might be different on different Windows versions.) - -Running ZeroTier One on a Mac is the same, but OSX requires a kernel extension. We ship a signed binary build of the ZeroTier tap device driver, which can be installed on Mac with: - - sudo make install-mac-tap - -This will create the home folder for Mac, place *tap.kext* there, and set its modes correctly to enable ZeroTier One to manage it with *kextload* and *kextunload*. - -### Troubleshooting - -For most users, it just works. - -If you are running a local system firewall, we recommend adding a rule permitting UDP port 9993 inbound and outbound. If you installed binaries for Windows this should be done automatically. Other platforms might require manual editing of local firewall rules depending on your configuration. - -The Mac firewall can be found under "Security" in System Preferences. Linux has a variety of firewall configuration systems and tools. If you're using Ubuntu's *ufw*, you can do this: - - sudo ufw allow 9993/udp - -On CentOS check `/etc/sysconfig/iptables` for IPTables rules. For other distributions consult your distribution's documentation. You'll also have to check the UIs or documentation for commercial third party firewall applications like Little Snitch (Mac), McAfee Firewall Enterprise (Windows), etc. if you are running any of those. Some corporate environments might have centrally managed firewall software, so you might also have to contact IT. - -ZeroTier One peers will automatically locate each other and communicate directly over a local wired LAN *if UDP port 9993 inbound is open*. If that port is filtered, they won't be able to see each others' LAN announcement packets. If you're experiencing poor performance between devices on the same physical network, check their firewall settings. Without LAN auto-location peers must attempt "loopback" NAT traversal, which sometimes fails and in any case requires that every packet traverse your external router twice. - -Users behind certain types of firewalls and "symmetric" NAT devices may not able able to connect to external peers directly at all. ZeroTier has limited support for port prediction and will *attempt* to traverse symmetric NATs, but this doesn't always work. If P2P connectivity fails you'll be bouncing UDP packets off our relay servers resulting in slower performance. Some NAT router(s) have a configurable NAT mode, and setting this to "full cone" will eliminate this problem. If you do this you may also see a magical improvement for things like VoIP phones, Skype, BitTorrent, WebRTC, certain games, etc., since all of these use NAT traversal techniques similar to ours. - -If you're interested, there's a [technical deep dive about NAT traversal on our blog](https://www.zerotier.com/blog/?p=226). A troubleshooting tool to help you diagnose NAT issues is planned for the future as are uPnP/IGD/NAT-PMP and IPv6 transport. - -If a firewall between you and the Internet blocks ZeroTier's UDP traffic, you will fall back to last-resort TCP tunneling to rootservers over port 443 (https impersonation). This will work almost anywhere but is *very slow* compared to UDP or direct peer to peer connectivity. - -### Contributing - -Please make pull requests against the `dev` branch.

These are: - - * A bug causing unreliable multicast propagation (GitHub issue #461). - * A crash in ARM binaries due to a build chain and flags problem. - * A bug in the network controller preventing members from being listed (GitHub issue #460). - ------- - -# 2017-03-14 -- Version 1.2.0 - -Version 1.2.0 is a major milestone release representing almost nine months of work. It includes our rules engine for distributed network packet filtering and security monitoring, federated roots, and many other architectural and UI improvements and bug fixes. - -## New Features in 1.2.0 - -### The ZeroTier Rules Engine - -The largest new feature in 1.2.0, and the product of many months of work, is our advanced network rules engine. With this release we achieve traffic control, security monitoring, and micro-segmentation capability on par with many enterprise SDN solutions designed for use in advanced data centers and corporate networks. - -Rules allow you to filter packets on your network and vector traffic to security observers. Security observation can be performed in-band using REDIRECT or out of band using TEE. - -Tags and capabilites provide advanced methods for implementing fine grained permission structures and micro-segmentation schemes without bloating the size and complexity of your rules table. - -See the [rules engine announcement blog post](https://www.zerotier.com/blog/?p=927) for an in-depth discussion of theory and implementation. The [manual](https://www.zerotier.com/manual.shtml) contains detailed information on rule, tag, and capability use, and the `rule-compiler/` subfolder of the ZeroTier source tree contains a JavaScript function to compile rules in our human-readable rule definition language into rules suitable for import into a network controller. (ZeroTier Central uses this same script to compile rules on [my.zerotier.com](https://my.zerotier.com/).) - -### Root Server Federation - -It's now possible to create your own root servers and add them to the root server pool on your nodes. This is done by creating what's called a "moon," which is a signed enumeration of root servers and their stable points on the network. Refer to the [manual](https://www.zerotier.com/manual.shtml) for instructions. - -Federated roots achieve a number of things: - - * You can deploy your own infrastructure to reduce dependency on ours. - * You can deploy roots *inside your LAN* to ensure that network connectivity inside your facility still works if the Internet goes down. This is the first step toward making ZeroTier viable as an in-house SDN solution. - * Roots can be deployed inside national boundaries for countries with data residency laws or "great firewalls." (As of 1.2.0 there is still no way to force all traffic to use these roots, but that will be easy to do in a later version.) - * Last but not least this makes ZeroTier somewhat less centralized by eliminating any hard dependency on ZeroTier, Inc.'s infrastructure. - -Our roots will of course remain and continue to provide zero-configuration instant-on deployment, a secure global authority for identities, and free traffic relaying for those who can't establish peer to peer connections. - -### Local Configuration - -An element of our design philosophy is "features are bugs." This isn't an absolute dogma but more of a guiding principle. We try as hard as we can to avoid adding features, especially "knobs" that must be tweaked by a user. - -As of 1.2.0 we've decided that certain knobs are unavoidable, and so there is now a `local.conf` file that can be used to configure them. See the ZeroTier One documentation for these. They include: - - * Blacklisting interfaces you want to make sure ZeroTier doesn't use for network traffic, such as VPNs, slow links, or backplanes designated for only certain kinds of traffic. - * Turning uPnP/NAT-PMP on or off. - * Configuring software updates on Windows and Mac platforms. - * Defining trusted paths (the old trusted paths file is now deprecated) - * Setting the ZeroTier main port so it doesn't have to be changed on the command line, which is very inconvenient in many cases. - -### Improved In-Band Software Updates - -A good software update system for Windows and Mac clients has been a missing feature in previous versions. It does exist but we've been shy about using it so far due to its fragility in some environments. - -We've greatly improved this mechanism in 1.2.0. Not only does it now do a better job of actually invoking the update, but it also transfers updates in-band using the ZeroTier protocol. This means it can work in environments that do not allows http/https traffic or that force it through proxies. There's also now an update channel setting: `beta` or `release` (the default). - -Software updates are authenticated three ways: - - 1. ZeroTier's own signing key is used to sign all updates and this signature is checked prior to installation. ZeroTier, Inc.'s signatures are performed on an air-gapped machine. - - 2. Updates for Mac and Windows are signed using Apple and Microsoft (DigiCert EV) keys and will not install unless these signatures are also valid. - - 3. The new in-band update mechanism also authenticates the source of the update via ZeroTier's built-in security features. This provides transport security, while 1 and 2 provide security of the update at rest. - -Updates are now configurable via `local.conf`. There are three options: `disable`, `download`, and `apply`. The third (apply) is the default for official builds on Windows and Mac, making updates happen silently and automatically as they do for popular browsers like Chrome and Firefox. Updates are disabled by default on Linux and other Unix-type systems as these are typically updated through package managers. - -### Path Link Quality Awareness - -Version 1.2.0 is now aware of the link quality of direct paths with other 1.2.0 nodes. This information isn't used yet but is visible through the JSON API. (Quality always shows as 100% with pre-1.2.0 nodes.) Quality is measured passively with no additional overhead using a counter based packet loss detection algorithm. - -This information is visible from the command line via `listpeers`: - - 200 listpeers XXXXXXXXXX 199.XXX.XXX.XXX/9993;10574;15250;1.00 48 1.2.0 LEAF - 200 listpeers XXXXXXXXXX 195.XXX.XXX.XXX/45584;467;7608;0.44 290 1.2.0 LEAF - -The first peer's path is at 100% (1.00), while the second peer's path is suffering quite a bit of packet loss (0.44). - -Link quality awareness is a precursor to intelligent multi-path and QoS support, which will in future versions bring us to feature parity with SD-WAN products like Cisco iWAN. - -### Security Improvements - -Version 1.2.0 adds anti-DOS (denial of service) rate limits and other hardening for improved resiliency against a number of denial of service attack scenarios. - -It also adds a mechanism for instantaneous credential revocation. This can be used to revoke certificates of membership instantly to kick a node off a network (for private networks) and also to revoke capabilities and tags. The new controller sends revocations by default when a peer is de-authorized. - -Revocations propagate using a "rumor mill" peer to peer algorithm. This means that a controller need only successfully send a revocation to at least one member of a network with connections to other active members. At this point the revocation will flood through the network peer to peer very quickly. This helps make revocations more robust in the face of poor connectivity with the controller or attempts to incapacitate the controller with denial of service attacks, as well as making revocations faster on huge networks. - -### Windows and Macintosh UI Improvements (ZeroTier One) - -The Mac has a whole new UI built natively in Objective-C. It provides a pulldown similar in appearance and operation to the Mac WiFi task bar menu. - -The Windows UI has also been improved and now provides a task bar icon that can be right-clicked to manage networks. Both now expose managed route and IP permissions, allowing nodes to easily opt in to full tunnel operation if you have a router configured on your network. - -### Ad-Hoc Networks - -A special kind of public network called an ad-hoc network may be accessed by joining a network ID with the format: - - ffSSSSEEEE000000 - | | | | - | | | Reserved for future use, must be 0 - | | End of port range (hex) - | Start of port range (hex) - Reserved ZeroTier address prefix indicating a controller-less network - -Ad-hoc networks are public (no access control) networks that have no network controller. Instead their configuration and other credentials are generated locally. Ad-hoc networks permit only IPv6 UDP and TCP unicast traffic (no multicast or broadcast) using 6plane format NDP-emulated IPv6 addresses. In addition an ad-hoc network ID encodes an IP port range. UDP packets and TCP SYN (connection open) packets are only allowed to desintation ports within the encoded range. - -For example `ff00160016000000` is an ad-hoc network allowing only SSH, while `ff0000ffff000000` is an ad-hoc network allowing any UDP or TCP port. - -Keep in mind that these networks are public and anyone in the entire world can join them. Care must be taken to avoid exposing vulnerable services or sharing unwanted files or other resources. - -### Network Controller (Partial) Rewrite - -The network controller has been largely rewritten to use a simple in-filesystem JSON data store in place of SQLite, and it is now included by default in all Windows, Mac, Linux, and BSD builds. This means any desktop or server node running ZeroTier One can now be a controller with no recompilation needed. - -If you have data in an old SQLite3 controller we've included a NodeJS script in `controller/migrate-sqlite` to migrate data to the new format. If you don't migrate, members will start getting `NOT_FOUND` when they attempt to query for updates. - -## Major Bug Fixes in 1.2.0 - - * **The Windows HyperV 100% CPU bug is FINALLY DEAD**: This long-running problem turns out to have been an issue with Windows itself, but one we were triggering by placing invalid data into the Windows registry. Microsoft is aware of the issue but we've also fixed the triggering problem on our side. ZeroTier should now co-exist quite well with HyperV and should now be able to be bridged with a HyperV virtual switch. - * **Segmenation faults on musl-libc based Linux systems**: Alpine Linux and some embedded Linux systems that use musl libc (a minimal libc) experienced segmentation faults. These were due to a smaller default stack size. A work-around that sets the stack size for new threads has been added. - * **Windows firewall blocks local JSON API**: On some Windows systems the firewall likes to block 127.0.0.1:9993 for mysterious reasons. This is now fixed in the installer via the addition of another firewall exemption rule. - * **UI crash on embedded Windows due to missing fonts**: The MSI installer now ships fonts and will install them if they are not present, so this should be fixed. - -## Other Improvements in 1.2.0 - - * **Improved dead path detection**: ZeroTier is now more aggressive about expiring paths that do not seem to be active. If a path seems marginal it is re-confirmed before re-use. - * **Minor performance improvements**: We've reduced unnecessary memcpy's and made a few other performance improvements in the core. - * **Linux static binaries**: For our official packages (the ones in the download.zerotier.com apt and yum repositories) we now build Linux binaries with static linking. Hopefully this will stop all the bug reports relating to library inconsistencies, as well as allowing our deb packages to run on a wider variety of Debian-based distributions. (There are far too many of these to support officially!) The overhead for this is very small, especially since we built our static versions against musl-libc. Distribution maintainers are of course free to build dynamically linked versions for inclusion into distributions; this only affects our official binaries. diff --git a/zto/controller/EmbeddedNetworkController.cpp b/zto/controller/EmbeddedNetworkController.cpp deleted file mode 100644 index ce56e90..0000000 --- a/zto/controller/EmbeddedNetworkController.cpp +++ /dev/null @@ -1,1850 +0,0 @@ -/* - * ZeroTier One - Network Virtualization Everywhere - * Copyright (C) 2011-2015 ZeroTier, Inc. - * - * This program is free software: you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This is our reference implementation and is the same one we use to power our own hosted services at [my.zerotier.com](https://my.zerotier.com/). Network controllers act as configuration servers and certificate authorities for the members of networks. Controllers are located on the network by simply parsing out the first 10 digits of a network's 16-digit network ID: these are the address of the controller. - -As of ZeroTier One version 1.2.0 this code is included in normal builds for desktop, laptop, and server (Linux, etc.) targets, allowing any device to create virtual networks without having to be rebuilt from source with special flags to enable this feature. While this does offer a convenient way to create ad-hoc networks or experiment, we recommend running a dedicated controller somewhere secure and stable for any "serious" use case. - -Controller data is stored in JSON format under `controller.d` in the ZeroTier working directory. It can be copied, rsync'd, placed in `git`, etc. The files under `controller.d` should not be modified in place while the controller is running or data loss may result, and if they are edited directly take care not to save corrupt JSON since that can also lead to data loss when the controller is restarted. Going through the API is strongly preferred to directly modifying these files. - -### Upgrading from Older (1.1.14 or earlier) Versions - -Older versions of this code used a SQLite database instead of in-filesystem JSON. A migration utility called `migrate-sqlite` is included here and *must* be used to migrate this data to the new format. If the controller is started with an old `controller.db` in its working directory it will terminate after printing an error to *stderr*. This is done to prevent "surprises" for those running DIY controllers using the old code. - -The migration tool is written in nodeJS and can be used like this: - - cd migrate-sqlite - npm install - node migrate.js - -Very old versions of nodeJS may have issues. We tested it with version 7. - -### Scalability and Reliability - -Controllers can in theory host up to 2^24 networks and serve many millions of devices (or more), but we recommend spreading large numbers of networks across many controllers for load balancing and fault tolerance reasons. Since the controller uses the filesystem as its data store we recommend fast filesystems and fast SSD drives for heavily loaded controllers. - -Since ZeroTier nodes are mobile and do not need static IPs, implementing high availability fail-over for controllers is easy. Just replicate their working directories from master to backup and have something automatically fire up the backup if the master goes down. Many modern orchestration tools have built-in support for this. It would also be possible in theory to run controllers on a replicated or distributed filesystem, but we haven't tested this yet. - -### Dockerizing Controllers - -ZeroTier network controllers can easily be run in Docker or other container systems. Since containers do not need to actually join networks, extra privilege options like "--device=/dev/net/tun --privileged" are not needed. You'll just need to map the local JSON API port of the running controller and allow it to access the Internet (over UDP/9993 at a minimum) so things can reach and query it. - -### Network Controller API - -The controller API is hosted via the same JSON API endpoint that ZeroTier One uses for local control (usually at 127.0.0.1 port 9993). All controller options are routed under the `/controller` base path. - -The controller microservice does not implement any fine-grained access control (authentication is via authtoken.secret just like the regular JSON API) or other complex mangement features. It just takes network and network member configurations and reponds to controller queries. We have an enterprise product called [ZeroTier Central](https://my.zerotier.com/) that we host as a service (and that companies can license to self-host) that does this. - -All working network IDs on a controller must begin with the controller's ZeroTier address. The API will *allow* "foreign" networks to be added but the controller will have no way of doing anything with them since nobody will know to query it. (In the future we might support secondaries, which would make this relevant.) - -The JSON API is *very* sensitive about types. Integers must be integers and strings strings, etc. Incorrectly typed and unrecognized fields may result in ignored fields or a 400 (bad request) error. - -#### `/controller` - - * Purpose: Check for controller function and return controller status - * Methods: GET - * Returns: { object } - -| Field | Type | Description | Writable | -| ------------------ | ----------- | ------------------------------------------------- | -------- | -| controller | boolean | Always 'true' | no | -| apiVersion | integer | Controller API version, currently 3 | no | -| clock | integer | Current clock on controller, ms since epoch | no | - -#### `/controller/network` - - * Purpose: List all networks hosted by this controller - * Methods: GET - * Returns: [ string, ... ] - -This returns an array of 16-digit hexadecimal network IDs. - -#### `/controller/network/` - - * Purpose: Create, configure, and delete hosted networks - * Methods: GET, POST, DELETE - * Returns: { object } - -By making queries to this path you can create, configure, and delete networks. DELETE is final, so don't do it unless you really mean it. - -When POSTing new networks take care that their IDs are not in use, otherwise you may overwrite an existing one. To create a new network with a random unused ID, POST to `/controller/network/##########______`. The #'s are the controller's 10-digit ZeroTier address and they're followed by six underscores. Check the `nwid` field of the returned JSON object for your network's newly allocated ID. Subsequent POSTs to this network must refer to its actual path. - -| Field | Type | Description | Writable | -| --------------------- | ------------- | ------------------------------------------------- | -------- | -| id | string | 16-digit network ID | no | -| nwid | string | 16-digit network ID (old, but still around) | no | -| clock | integer | Current clock, ms since epoch | no | -| name | string | A short name for this network | YES | -| private | boolean | Is access control enabled? | YES | -| enableBroadcast | boolean | Ethernet ff:ff:ff:ff:ff:ff allowed? | YES | -| allowPassiveBridging | boolean | Allow any member to bridge (very experimental) | YES | -| v4AssignMode | object | IPv4 management and assign options (see below) | YES | -| v6AssignMode | object | IPv6 management and assign options (see below) | YES | -| multicastLimit | integer | Maximum recipients for a multicast packet | YES | -| creationTime | integer | Time network was first created | no | -| revision | integer | Network config revision counter | no | -| authorizedMemberCount | integer | Number of authorized members (for private nets) | no | -| activeMemberCount | integer | Number of members that appear to be online | no | -| totalMemberCount | integer | Total known members of this network | no | -| routes | array[object] | Managed IPv4 and IPv6 routes; see below | YES | -| ipAssignmentPools | array[object] | IP auto-assign ranges; see below | YES | -| rules | array[object] | Traffic rules; see below | YES | - -Recent changes: - - * The `ipLocalRoutes` field appeared in older versions but is no longer present. Routes will now show up in `routes`. - * The `relays` field is gone since network preferred relays are gone. This capability is replaced by VL1 level federation ("federated roots"). - -Other important points: - - * Networks without rules won't carry any traffic. If you don't specify any on network creation an "accept anything" rule set will automatically be added. - * Managed IP address assignments and IP assignment pools that do not fall within a route configured in `routes` are ignored and won't be used or sent to members. - * The default for `private` is `true` and this is probably what you want. Turning `private` off means *anyone* can join your network with only its 16-digit network ID. It's also impossible to de-authorize a member as these networks don't issue or enforce certificates. Such "party line" networks are used for decentralized app backplanes, gaming, and testing but are otherwise not common. - -**Auto-Assign Modes:** - -Auto assign modes (`v4AssignMode` and `v6AssignMode`) contain objects that map assignment modes to booleans. - -For IPv4 the only valid setting is `zt` which, if true, causes IPv4 addresses to be auto-assigned from `ipAssignmentPools` to members that do not have an IPv4 assignment. Note that active bridges are exempt and will not get auto-assigned IPs since this can interfere with bridging. (You can still manually assign one if you want.) - -IPv6 includes this option and two others: `6plane` and `rfc4193`. These assign private IPv6 addresses to each member based on a deterministic assignment scheme that allows members to emulate IPv6 NDP to skip multicast for better performance and scalability. The `rfc4193` mode gives every member a /128 on a /88 network, while `6plane` gives every member a /80 within a /40 network but uses NDP emulation to route *all* IPs under that /80 to its owner. The `6plane` mode is great for use cases like Docker since it allows every member to assign IPv6 addresses within its /80 that just work instantly and globally across the network. - -**IP assignment pool object format:** - -| Field | Type | Description | -| --------------------- | ------------- | ------------------------------------------------- | -| ipRangeStart | string | Starting IP address in range | -| ipRangeEnd | string | Ending IP address in range (inclusive) | - -Pools are only used if auto-assignment is on for the given address type (IPv4 or IPv6) and if the entire range falls within a managed route. - -IPv6 ranges work just like IPv4 ranges and look like this: - - { - "ipRangeStart": "fd00:feed:feed:beef:0000:0000:0000:0000", - "ipRangeEnd": "fd00:feed:feed:beef:ffff:ffff:ffff:ffff" - } - -(You can POST a shortened-form IPv6 address but the API will always report back un-shortened canonical form addresses.) - -That defines a range within network `fd00:feed:feed:beef::/64` that contains up to 2^64 addresses. If an IPv6 range is large enough, the controller will assign addresses by placing each member's device ID into the address in a manner similar to the RFC4193 and 6PLANE modes. Otherwise it will assign addresses at random. - -**Rule object format:** - -Each rule is actually a sequence of zero or more `MATCH_` entries in the rule array followed by an `ACTION_` entry that describes what to do if all the preceding entries match. An `ACTION_` without any preceding `MATCH_` entries is always taken, so setting a single `ACTION_ACCEPT` rule yields a network that allows all traffic. If no rules are present the default action is `ACTION_DROP`. - -Rules are evaluated in the order in which they appear in the array. There is currently a limit of 256 entries per network. Capabilities should be used if a larger and more complex rule set is needed since they allow rules to be grouped by purpose and only shipped to members that need them. - -Each rule table entry has two common fields. - -| Field | Type | Description | -| --------------------- | ------------- | ------------------------------------------------- | -| type | string | Entry type (all caps, case sensitive) | -| not | boolean | If true, MATCHes match if they don't match | - -The following fields may or may not be present depending on rule type: - -| Field | Type | Description | -| --------------------- | ------------- | ------------------------------------------------- | -| zt | string | 10-digit hex ZeroTier address | -| etherType | integer | Ethernet frame type | -| mac | string | Hex MAC address (with or without :'s) | -| ip | string | IPv4 or IPv6 address | -| ipTos | integer | IP type of service | -| ipProtocol | integer | IP protocol (e.g. TCP) | -| start | integer | Start of an integer range (e.g. port range) | -| end | integer | End of an integer range (inclusive) | -| id | integer | Tag ID | -| value | integer | Tag value or comparison value | -| mask | integer | Bit mask (for characteristics flags) | - -The entry types and their additional fields are: - -| Entry type | Description | Fields | -| ------------------------------- | ----------------------------------------------------------------- | -------------- | -| `ACTION_DROP` | Drop any packets matching this rule | (none) | -| `ACTION_ACCEPT` | Accept any packets matching this rule | (none) | -| `ACTION_TEE` | Send a copy of this packet to a node (rule parsing continues) | `zt` | -| `ACTION_REDIRECT` | Redirect this packet to another node | `zt` | -| `ACTION_DEBUG_LOG` | Output debug info on match (if built with rules engine debug) | (none) | -| `MATCH_SOURCE_ZEROTIER_ADDRESS` | Match VL1 ZeroTier address of packet sender. | `zt` | -| `MATCH_DEST_ZEROTIER_ADDRESS` | Match VL1 ZeroTier address of recipient | `zt` | -| `MATCH_ETHERTYPE` | Match Ethernet frame type | `etherType` | -| `MATCH_MAC_SOURCE` | Match source Ethernet MAC address | `mac` | -| `MATCH_MAC_DEST` | Match destination Ethernet MAC address | `mac` | -| `MATCH_IPV4_SOURCE` | Match source IPv4 address | `ip` | -| `MATCH_IPV4_DEST` | Match destination IPv4 address | `ip` | -| `MATCH_IPV6_SOURCE` | Match source IPv6 address | `ip` | -| `MATCH_IPV6_DEST` | Match destination IPv6 address | `ip` | -| `MATCH_IP_TOS` | Match IP TOS field | `ipTos` | -| `MATCH_IP_PROTOCOL` | Match IP protocol field | `ipProtocol` | -| `MATCH_IP_SOURCE_PORT_RANGE` | Match a source IP port range | `start`,`end` | -| `MATCH_IP_DEST_PORT_RANGE` | Match a destination IP port range | `start`,`end` | -| `MATCH_CHARACTERISTICS` | Match on characteristics flags | `mask`,`value` | -| `MATCH_FRAME_SIZE_RANGE` | Match a range of Ethernet frame sizes | `start`,`end` | -| `MATCH_TAGS_SAMENESS` | Match if both sides' tags differ by no more than value | `id`,`value` | -| `MATCH_TAGS_BITWISE_AND` | Match if both sides' tags AND to value | `id`,`value` | -| `MATCH_TAGS_BITWISE_OR` | Match if both sides' tags OR to value | `id`,`value` | -| `MATCH_TAGS_BITWISE_XOR` | Match if both sides` tags XOR to value | `id`,`value` | - -Important notes about rules engine behavior: - - * IPv4 and IPv6 IP address rules do not match for frames that are not IPv4 or IPv6 respectively. - * `ACTION_DEBUG_LOG` is a no-op on nodes not built with `ZT_RULES_ENGINE_DEBUGGING` enabled (see Network.cpp). If that is enabled nodes will dump a trace of rule evaluation results to *stdout* when this action is encountered but will otherwise keep evaluating rules. This is used for basic "smoke testing" of the rules engine. - * Multicast packets and packets destined for bridged devices treated a little differently. They are matched more than once. They are matched at the point of send with a NULL ZeroTier destination address, meaning that `MATCH_DEST_ZEROTIER_ADDRESS` is useless. That's because the true VL1 destination is not yet known. Then they are matched again for each true VL1 destination. On these later subsequent matches TEE actions are ignored and REDIRECT rules are interpreted as DROPs. This prevents multiple TEE or REDIRECT packets from being sent to third party devices. - * Rules in capabilities are always matched as if the current device is the sender (inbound == false). A capability specifies sender side rules that can be enforced on both sides. - -#### `/controller/network//member` - - * Purpose: Get a set of all members on this network - * Methods: GET - * Returns: { object } - -This returns a JSON object containing all member IDs as keys and their `memberRevisionCounter` values as values. - -#### `/controller/network//active` - - * Purpose: Get a set of all active members on this network - * Methods: GET - * Returns: { object } - -This returns an object containing all currently online members and the most recent `recentLog` entries for their last request. - -#### `/controller/network//member/

It parses both requests and -responses. The parser is designed to be used in performance HTTP -applications. It does not make any syscalls nor allocations, it does not -buffer data, it can be interrupted at anytime. Depending on your -architecture, it only requires about 40 bytes of data per message -stream (in a web server that is per connection). - -Features: - - * No dependencies - * Handles persistent streams (keep-alive). - * Decodes chunked encoding. - * Upgrade support - * Defends against buffer overflow attacks. - -The parser extracts the following information from HTTP messages: - - * Header fields and values - * Content-Length - * Request method - * Response status code - * Transfer-Encoding - * HTTP version - * Request URL - * Message body - - -Usage ------ - -One `http_parser` object is used per TCP connection. Initialize the struct -using `http_parser_init()` and set the callbacks. That might look something -like this for a request parser: -```c -http_parser_settings settings; -settings.on_url = my_url_callback; -settings.on_header_field = my_header_field_callback; -/* ... */ - -http_parser *parser = malloc(sizeof(http_parser)); -http_parser_init(parser, HTTP_REQUEST); -parser->data = my_socket; -``` - -When data is received on the socket execute the parser and check for errors. - -```c -size_t len = 80*1024, nparsed; -char buf[len]; -ssize_t recved; - -recved = recv(fd, buf, len, 0); - -if (recved < 0) { - /* Handle error. */ -} - -/* Start up / continue the parser. - * Note we pass recved==0 to signal that EOF has been received. - */ -nparsed = http_parser_execute(parser, &settings, buf, recved); - -if (parser->upgrade) { - /* handle new protocol */ -} else if (nparsed != recved) { - /* Handle error. Usually just close the connection. */ -} -``` - -HTTP needs to know where the end of the stream is. For example, sometimes -servers send responses without Content-Length and expect the client to -consume input (for the body) until EOF. To tell http_parser about EOF, give -`0` as the fourth parameter to `http_parser_execute()`. Callbacks and errors -can still be encountered during an EOF, so one must still be prepared -to receive them. - -Scalar valued message information such as `status_code`, `method`, and the -HTTP version are stored in the parser structure. This data is only -temporally stored in `http_parser` and gets reset on each new message. If -this information is needed later, copy it out of the structure during the -`headers_complete` callback. - -The parser decodes the transfer-encoding for both requests and responses -transparently. That is, a chunked encoding is decoded before being sent to -the on_body callback. - - -The Special Problem of Upgrade ------------------------------- - -HTTP supports upgrading the connection to a different protocol. An -increasingly common example of this is the WebSocket protocol which sends -a request like - - GET /demo HTTP/1.1 - Upgrade: WebSocket - Connection: Upgrade - Host: example.com - Origin: http://example.com - WebSocket-Protocol: sample - -followed by non-HTTP data. - -(See [RFC6455](https://tools.ietf.org/html/rfc6455) for more information the -WebSocket protocol.) - -To support this, the parser will treat this as a normal HTTP message without a -body, issuing both on_headers_complete and on_message_complete callbacks. However -http_parser_execute() will stop parsing at the end of the headers and return. - -The user is expected to check if `parser->upgrade` has been set to 1 after -`http_parser_execute()` returns. Non-HTTP data begins at the buffer supplied -offset by the return value of `http_parser_execute()`. - - -Callbacks ---------- - -During the `http_parser_execute()` call, the callbacks set in -`http_parser_settings` will be executed. The parser maintains state and -never looks behind, so buffering the data is not necessary. If you need to -save certain data for later usage, you can do that from the callbacks. - -There are two types of callbacks: - -* notification `typedef int (*http_cb) (http_parser*);` - Callbacks: on_message_begin, on_headers_complete, on_message_complete. -* data `typedef int (*http_data_cb) (http_parser*, const char *at, size_t length);` - Callbacks: (requests only) on_url, - (common) on_header_field, on_header_value, on_body; - -Callbacks must return 0 on success. Returning a non-zero value indicates -error to the parser, making it exit immediately. - -For cases where it is necessary to pass local information to/from a callback, -the `http_parser` object's `data` field can be used. -An example of such a case is when using threads to handle a socket connection, -parse a request, and then give a response over that socket. By instantiation -of a thread-local struct containing relevant data (e.g. accepted socket, -allocated memory for callbacks to write into, etc), a parser's callbacks are -able to communicate data between the scope of the thread and the scope of the -callback in a threadsafe manner. This allows http-parser to be used in -multi-threaded contexts. - -Example: -```c - typedef struct { - socket_t sock; - void* buffer; - int buf_len; - } custom_data_t; - - -int my_url_callback(http_parser* parser, const char *at, size_t length) { - /* access to thread local custom_data_t struct. - Use this access save parsed data for later use into thread local - buffer, or communicate over socket - */ - parser->data; - ... - return 0; -} - -... - -void http_parser_thread(socket_t sock) { - int nparsed = 0; - /* allocate memory for user data */ - custom_data_t *my_data = malloc(sizeof(custom_data_t)); - - /* some information for use by callbacks. - * achieves thread -> callback information flow */ - my_data->sock = sock; - - /* instantiate a thread-local parser */ - http_parser *parser = malloc(sizeof(http_parser)); - http_parser_init(parser, HTTP_REQUEST); /* initialise parser */ - /* this custom data reference is accessible through the reference to the - parser supplied to callback functions */ - parser->data = my_data; - - http_parser_settings settings; /* set up callbacks */ - settings.on_url = my_url_callback; - - /* execute parser */ - nparsed = http_parser_execute(parser, &settings, buf, recved); - - ... - /* parsed information copied from callback. - can now perform action on data copied into thread-local memory from callbacks. - achieves callback -> thread information flow */ - my_data->buffer; - ... -} - -``` - -In case you parse HTTP message in chunks (i.e. `read()` request line -from socket, parse, read half headers, parse, etc) your data callbacks -may be called more than once. Http-parser guarantees that data pointer is only -valid for the lifetime of callback. You can also `read()` into a heap allocated -buffer to avoid copying memory around if this fits your application. - -Reading headers may be a tricky task if you read/parse headers partially. -Basically, you need to remember whether last header callback was field or value -and apply the following logic: - - (on_header_field and on_header_value shortened to on_h_*) - ------------------------ ------------ -------------------------------------------- - | State (prev. callback) | Callback | Description/action | - ------------------------ ------------ -------------------------------------------- - | nothing (first call) | on_h_field | Allocate new buffer and copy callback data | - | | | into it | - ------------------------ ------------ -------------------------------------------- - | value | on_h_field | New header started. | - | | | Copy current name,value buffers to headers | - | | | list and allocate new buffer for new name | - ------------------------ ------------ -------------------------------------------- - | field | on_h_field | Previous name continues.

Our class had these design goals: - -- **Intuitive syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the [examples below](#examples) and you'll know what I mean. - -- **Trivial integration**. Our whole code consists of a single header file [`json.hpp`](https://github.com/nlohmann/json/blob/develop/src/json.hpp). That's it. No library, no subproject, no dependencies, no complex build system. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings. - -- **Serious testing**. Our class is heavily [unit-tested](https://github.com/nlohmann/json/blob/master/test/src/unit.cpp) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](http://valgrind.org) that there are no memory leaks. To maintain high quality, the project is following the [Core Infrastructure Initiative (CII) best practices](https://bestpractices.coreinfrastructure.org/projects/289). - -Other aspects were not so important to us: - -- **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: `std::string` for strings, `int64_t`, `uint64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. However, you can template the generalized class `basic_json` to your needs. - -- **Speed**. We currently implement the parser as naive [recursive descent parser](http://en.wikipedia.org/wiki/Recursive_descent_parser) with hand coded string handling. It is fast enough, but a [LALR-parser](http://en.wikipedia.org/wiki/LALR_parser) may be even faster (but would consist of more files which makes the integration harder). - -See the [contribution guidelines](https://github.com/nlohmann/json/blob/master/.github/CONTRIBUTING.md#please-dont) for more information. - - -## Integration - -The single required source, file `json.hpp` is in the `src` directory or [released here](https://github.com/nlohmann/json/releases). All you need to do is add - -```cpp -#include "json.hpp" - -// for convenience -using json = nlohmann::json; -``` - -to the files you want to use JSON objects. That's it. Do not forget to set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang). - -:beer: If you are using OS X and [Homebrew](http://brew.sh), just type `brew tap nlohmann/json` and `brew install nlohmann_json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann_json --HEAD`. - - -## Examples - -Here are some examples to give you an idea how to use the class. - -Assume you want to create the JSON object - -```json -{ - "pi": 3.141, - "happy": true, - "name": "Niels", - "nothing": null, - "answer": { - "everything": 42 - }, - "list": [1, 0, 2], - "object": { - "currency": "USD", - "value": 42.99 - } -} -``` - -With the JSON class, you could write: - -```cpp -// create an empty structure (null) -json j; - -// add a number that is stored as double (note the implicit conversion of j to an object) -j["pi"] = 3.141; - -// add a Boolean that is stored as bool -j["happy"] = true; - -// add a string that is stored as std::string -j["name"] = "Niels"; - -// add another null object by passing nullptr -j["nothing"] = nullptr; - -// add an object inside the object -j["answer"]["everything"] = 42; - -// add an array that is stored as std::vector (using an initializer list) -j["list"] = { 1, 0, 2 }; - -// add another object (using an initializer list of pairs) -j["object"] = { {"currency", "USD"}, {"value", 42.99} }; - -// instead, you could also write (which looks very similar to the JSON above) -json j2 = { - {"pi", 3.141}, - {"happy", true}, - {"name", "Niels"}, - {"nothing", nullptr}, - {"answer", { - {"everything", 42} - }}, - {"list", {1, 0, 2}}, - {"object", { - {"currency", "USD"}, - {"value", 42.99} - }} -}; -``` - -Note that in all these cases, you never need to "tell" the compiler which JSON value you want to use. If you want to be explicit or express some edge cases, the functions `json::array` and `json::object` will help: - -```cpp -// a way to express the empty array [] -json empty_array_explicit = json::array(); - -// ways to express the empty object {} -json empty_object_implicit = json({}); -json empty_object_explicit = json::object(); - -// a way to express an _array_ of key/value pairs [["currency", "USD"], ["value", 42.99]] -json array_not_object = { json::array({"currency", "USD"}), json::array({"value", 42.99}) }; -``` - - -### Serialization / Deserialization - -You can create an object (deserialization) by appending `_json` to a string literal: - -```cpp -// create object from string literal -json j = "{ \"happy\": true, \"pi\": 3.141 }"_json; - -// or even nicer with a raw string literal -auto j2 = R"( - { - "happy": true, - "pi": 3.141 - } -)"_json; - -// or explicitly -auto j3 = json::parse("{ \"happy\": true, \"pi\": 3.141 }"); -``` - -You can also get a string representation (serialize): - -```cpp -// explicit conversion to string -std::string s = j.dump(); // {\"happy\":true,\"pi\":3.141} - -// serialization with pretty printing -// pass in the amount of spaces to indent -std::cout << j.dump(4) << std::endl; -// { -// "happy": true, -// "pi": 3.141 -// } -``` - -You can also use streams to serialize and deserialize: - -```cpp -// deserialize from standard input -json j; -std::cin >> j; - -// serialize to standard output -std::cout << j; - -// the setw manipulator was overloaded to set the indentation for pretty printing -std::cout << std::setw(4) << j << std::endl; -``` - -These operators work for any subclasses of `std::istream` or `std::ostream`. - -Please note that setting the exception bit for `failbit` is inappropriate for this use case. It will result in program termination due to the `noexcept` specifier in use. - - -### STL-like access - -We designed the JSON class to behave just like an STL container. In fact, it satisfies the [**ReversibleContainer**](http://en.cppreference.com/w/cpp/concept/ReversibleContainer) requirement. - -```cpp -// create an array using push_back -json j; -j.push_back("foo"); -j.push_back(1); -j.push_back(true); - -// iterate the array -for (json::iterator it = j.begin(); it != j.end(); ++it) { - std::cout << *it << '\n'; -} - -// range-based for -for (auto& element : j) { - std::cout << element << '\n'; -} - -// getter/setter -const std::string tmp = j[0]; -j[1] = 42; -bool foo = j.at(2); - -// other stuff -j.size(); // 3 entries -j.empty(); // false -j.type(); // json::value_t::array -j.clear(); // the array is empty again - -// convenience type checkers -j.is_null(); -j.is_boolean(); -j.is_number(); -j.is_object(); -j.is_array(); -j.is_string(); - -// comparison -j == "[\"foo\", 1, true]"_json; // true - -// create an object -json o; -o["foo"] = 23; -o["bar"] = false; -o["baz"] = 3.141; - -// special iterator member functions for objects -for (json::iterator it = o.begin(); it != o.end(); ++it) { - std::cout << it.key() << " : " << it.value() << "\n"; -} - -// find an entry -if (o.find("foo") != o.end()) { - // there is an entry with key "foo" -} - -// or simpler using count() -int foo_present = o.count("foo"); // 1 -int fob_present = o.count("fob"); // 0 - -// delete an entry -o.erase("foo"); -``` - - -### Conversion from STL containers - -Any sequence container (`std::array`, `std::vector`, `std::deque`, `std::forward_list`, `std::list`) whose values can be used to construct JSON types (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. The same holds for similar associative containers (`std::set`, `std::multiset`, `std::unordered_set`, `std::unordered_multiset`), but in these cases the order of the elements of the array depends how the elements are ordered in the respective STL container. - -```cpp -std::vector c_vector {1, 2, 3, 4}; -json j_vec(c_vector); -// [1, 2, 3, 4] - -std::deque c_deque {1.2, 2.3, 3.4, 5.6}; -json j_deque(c_deque); -// [1.2, 2.3, 3.4, 5.6] - -std::list c_list {true, true, false, true}; -json j_list(c_list); -// [true, true, false, true] - -std::forward_list c_flist {12345678909876, 23456789098765, 34567890987654, 45678909876543}; -json j_flist(c_flist); -// [12345678909876, 23456789098765, 34567890987654, 45678909876543] - -std::array c_array {{1, 2, 3, 4}}; -json j_array(c_array); -// [1, 2, 3, 4] - -std::set c_set {"one", "two", "three", "four", "one"}; -json j_set(c_set); // only one entry for "one" is used -// ["four", "one", "three", "two"] - -std::unordered_set c_uset {"one", "two", "three", "four", "one"}; -json j_uset(c_uset); // only one entry for "one" is used -// maybe ["two", "three", "four", "one"] - -std::multiset c_mset {"one", "two", "one", "four"}; -json j_mset(c_mset); // both entries for "one" are used -// maybe ["one", "two", "one", "four"] - -std::unordered_multiset c_umset {"one", "two", "one", "four"}; -json j_umset(c_umset); // both entries for "one" are used -// maybe ["one", "two", "one", "four"] -``` - -Likewise, any associative key-value containers (`std::map`, `std::multimap`, `std::unordered_map`, `std::unordered_multimap`) whose keys can construct an `std::string` and whose values can be used to construct JSON types (see examples above) can be used to to create a JSON object. Note that in case of multimaps only one key is used in the JSON object and the value depends on the internal order of the STL container. - -```cpp -std::map c_map { {"one", 1}, {"two", 2}, {"three", 3} }; -json j_map(c_map); -// {"one": 1, "three": 3, "two": 2 } - -std::unordered_map c_umap { {"one", 1.2}, {"two", 2.3}, {"three", 3.4} }; -json j_umap(c_umap); -// {"one": 1.2, "two": 2.3, "three": 3.4} - -std::multimap c_mmap { {"one", true}, {"two", true}, {"three", false}, {"three", true} }; -json j_mmap(c_mmap); // only one entry for key "three" is used -// maybe {"one": true, "two": true, "three": true} - -std::unordered_multimap c_ummap { {"one", true}, {"two", true}, {"three", false}, {"three", true} }; -json j_ummap(c_ummap); // only one entry for key "three" is used -// maybe {"one": true, "two": true, "three": true} -``` - -### JSON Pointer and JSON Patch - -The library supports **JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) as alternative means to address structured values. On top of this, **JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) allows to describe differences between two JSON values - effectively allowing patch and diff operations known from Unix. - -```cpp -// a JSON value -json j_original = R"({ - "baz": ["one", "two", "three"], - "foo": "bar" -})"_json; - -// access members with a JSON pointer (RFC 6901) -j_original["/baz/1"_json_pointer]; -// "two" - -// a JSON patch (RFC 6902) -json j_patch = R"([ - { "op": "replace", "path": "/baz", "value": "boo" }, - { "op": "add", "path": "/hello", "value": ["world"] }, - { "op": "remove", "path": "/foo"} -])"_json; - -// apply the patch -json j_result = j_original.patch(j_patch); -// { -// "baz": "boo", -// "hello": ["world"] -// } - -// calculate a JSON patch from two JSON values -json::diff(j_result, j_original); -// [ -// { "op":" replace", "path": "/baz", "value": ["one", "two", "three"] }, -// { "op": "remove","path": "/hello" }, -// { "op": "add", "path": "/foo", "value": "bar" } -// ] -``` - - -### Implicit conversions - -The type of the JSON object is determined automatically by the expression to store. Likewise, the stored value is implicitly converted. - -```cpp -// strings -std::string s1 = "Hello, world!"; -json js = s1; -std::string s2 = js; - -// Booleans -bool b1 = true; -json jb = b1; -bool b2 = jb; - -// numbers -int i = 42; -json jn = i; -double f = jn; - -// etc. -``` - -You can also explicitly ask for the value: - -```cpp -std::string vs = js.get(); -bool vb = jb.get(); -int vi = jn.get(); - -// etc. -``` - - -## Supported compilers - -Though it's 2016 already, the support for C++11 is still a bit sparse. Currently, the following compilers are known to work: - -- GCC 4.9 - 6.0 (and possibly later) -- Clang 3.4 - 3.9 (and possibly later) -- Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later) - -I would be happy to learn about other compilers/versions. - -Please note: - -- GCC 4.8 does not work because of two bugs ([55817](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55817) and [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824)) in the C++11 support. Note there is a [pull request](https://github.com/nlohmann/json/pull/212) to fix some of the issues. -- Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default. - - ``` - APP_STL := c++_shared - NDK_TOOLCHAIN_VERSION := clang3.6 - APP_CPPFLAGS += -frtti -fexceptions - ``` - - The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10. - -- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod`) may occur. Note this is not an issue with the code, but rather with the compiler itself. On Android, see above to build with a newer environment. For MinGW, please refer to [this site](http://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug.

If you are not sure whether an element in an object exists, use checked access with the [`at()` function](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a674de1ee73e6bf4843fc5dc1351fb726.html#a674de1ee73e6bf4843fc5dc1351fb726). -- As the exact type of a number is not defined in the [JSON specification](http://rfc7159.net/rfc7159), this library tries to choose the best fitting C++ number type automatically. As a result, the type `double` may be used to store numbers which may yield [**floating-point exceptions**](https://github.com/nlohmann/json/issues/181) in certain rare situations if floating-point exceptions have been unmasked in the calling code. These exceptions are not caused by the library and need to be fixed in the calling code, such as by re-masking the exceptions prior to calling library functions. -- The library supports **Unicode input** as follows: - - Only **UTF-8** encoded input is supported which is the default encoding for JSON according to [RFC 7159](http://rfc7159.net/rfc7159#rfc.section.8.1). - - Other encodings such as Latin-1, UTF-16, or UTF-32 are not supported and will yield parse errors. - - [Unicode noncharacters](http://www.unicode.org/faq/private_use.html#nonchar1) will not be replaced by the library. - - Invalid surrogates (e.g., incomplete pairs such as `\uDEAD`) will yield parse errors. - - -## Execute unit tests - -To compile and run the tests, you need to execute - -```sh -$ make check - -=============================================================================== -All tests passed (8905491 assertions in 36 test cases) -``` - -Alternatively, you can use [CMake](https://cmake.org) and run - -```sh -$ mkdir build -$ cd build -$ cmake .. -$ make -$ ctest -``` - -For more information, have a look at the file [.travis.yml](https://github.com/nlohmann/json/blob/master/.travis.yml). diff --git a/zto/ext/json/json.hpp b/zto/ext/json/json.hpp deleted file mode 100644 index 9d48e7a..0000000 --- a/zto/ext/json/json.hpp +++ /dev/null @@ -1,12275 +0,0 @@ -/* - __ _____ _____ _____ - __| | __| | | | JSON for Modern C++ -| | |__ | | | | | | version 2.0.10 -|_____|_____|_____|_|___| https://github.com/nlohmann/json - -Licensed under the MIT License . -Copyright (c) 2013-2017 Niels Lohmann . - -Permission is hereby granted, free of charge, to any person obtaining a copy -of this software and associated documentation files (the "Software"), to deal -in the Software without restriction, including without limitation the rights -to use, copy, modify, merge, publish, distribute, sublicense, and/or sell -copies of the Software, and to permit persons to whom the Software is -furnished to do so, subject to the following conditions: - -The above copyright notice and this permission notice shall be included in all -copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

It gives full buffer control to user. - Decompressing an lz4-compressed block also requires metadata (such as compressed size). - Each application is free to encode such metadata in whichever way it wants. - - An additional format, called LZ4 frame specification (doc/lz4_Frame_format.md), - take care of encoding standard metadata alongside LZ4-compressed blocks. - If your application requires interoperability, it's recommended to use it. - A library is provided to take care of it, see lz4frame.h. -*/ - -#define LZ4LIB_API - -/*========== Version =========== */ -#define LZ4_VERSION_MAJOR 1 /* for breaking interface changes */ -#define LZ4_VERSION_MINOR 7 /* for new (non-breaking) interface capabilities */ -#define LZ4_VERSION_RELEASE 5 /* for tweaks, bug-fixes, or development */ - -#define LZ4_VERSION_NUMBER (LZ4_VERSION_MAJOR *100*100 + LZ4_VERSION_MINOR *100 + LZ4_VERSION_RELEASE) - -#define LZ4_LIB_VERSION LZ4_VERSION_MAJOR.LZ4_VERSION_MINOR.LZ4_VERSION_RELEASE -#define LZ4_QUOTE(str) #str -#define LZ4_EXPAND_AND_QUOTE(str) LZ4_QUOTE(str) -#define LZ4_VERSION_STRING LZ4_EXPAND_AND_QUOTE(LZ4_LIB_VERSION) - -/*! - * LZ4_MEMORY_USAGE : - * Memory usage formula : N->2^N Bytes (examples : 10 -> 1KB; 12 -> 4KB ; 16 -> 64KB; 20 -> 1MB; etc.) - * Increasing memory usage improves compression ratio - * Reduced memory usage can improve speed, due to cache effect - * Default value is 14, for 16KB, which nicely fits into Intel x86 L1 cache - */ -#define LZ4_MEMORY_USAGE 14 - -#define LZ4_MAX_INPUT_SIZE 0x7E000000 /* 2 113 929 216 bytes */ -#define LZ4_COMPRESSBOUND(isize) ((unsigned)(isize) > (unsigned)LZ4_MAX_INPUT_SIZE ? 0 : (isize) + ((isize)/255) + 16) - -/*-********************************************* -* Streaming Compression Functions -***********************************************/ -typedef union LZ4_stream_u LZ4_stream_t; /* incomplete type (defined later) */ - -/*!

If a cipher is 256 bits strong and someone finds a way - * to reduce key search to 254 bits, this constitues a "break" in the academic - * literature. 254 bits is still far beyond what can be leveraged to accomplish - * a "break" as most people would understand it -- the actual decryption and - * reading of traffic. - * - * Nevertheless, "attacks only get better" as cryptographers like to say. As - * a result, they recommend not using anything that's shown any weakness even - * if that weakness is so far only meaningful to academics. It may be a sign - * of a deeper problem. - * - * So why choose a lower round count? - * - * Turns out the speed difference is nontrivial. On a Macbook Pro (Core i3) 20 - * rounds of SSE-optimized Salsa20 achieves ~508mb/sec/core, while 12 rounds - * hits ~832mb/sec/core. ZeroTier is designed for multiple objectives: - * security, simplicity, and performance. In this case a deference was made - * for performance. - * - * Meta discussion: - * - * The cipher is not the thing you should be paranoid about. - * - * I'll qualify that. If the cipher is known to be weak, like RC4, or has a - * key size that is too small, like DES, then yes you should worry about - * the cipher. - * - * But if the cipher is strong and your adversary is anyone other than the - * intelligence apparatus of a major superpower, you are fine in that - * department. - * - * Go ahead. Search for the last ten vulnerabilities discovered in SSL. Not - * a single one involved the breaking of a cipher. Now broaden your search. - * Look for issues with SSH, IPSec, etc. The only cipher-related issues you - * will find might involve the use of RC4 or MD5, algorithms with known - * issues or small key/digest sizes. But even weak ciphers are difficult to - * exploit in the real world -- you usually need a lot of data and a lot of - * compute time. No, virtually EVERY security vulnerability you will find - * involves a problem with the IMPLEMENTATION not with the cipher. - * - * A flaw in ZeroTier's protocol or code is incredibly, unbelievably - * more likely than a flaw in Salsa20 or any other cipher or cryptographic - * primitive it uses. We're talking odds of dying in a car wreck vs. odds of - * being personally impacted on the head by a meteorite. Nobody without a - * billion dollar budget is going to break into your network by actually - * cracking Salsa20/12 (or even /8) in the field. - * - * So stop worrying about the cipher unless you are, say, the Kremlin and your - * adversary is the NSA and the GCHQ.

It's designed to be small and maximally portable for future use on small embedded and special purpose systems. - -Code in here follows these guidelines: - - - Keep it minimal, especially in terms of code footprint and memory use. - - There should be no OS-dependent code here unless absolutely necessary (e.g. getSecureRandom). - - If it's not part of the core virtual Ethernet switch it does not belong here. - - No C++11 or C++14 since older and embedded compilers don't support it yet and this should be maximally portable. - - Minimize the use of complex C++ features since at some point we might end up "minus-minus'ing" this code if doing so proves necessary to port to tiny embedded systems. diff --git a/zto/node/Revocation.cpp b/zto/node/Revocation.cpp deleted file mode 100644 index bab5653..0000000 --- a/zto/node/Revocation.cpp +++ /dev/null @@ -1,46 +0,0 @@ -/* - * ZeroTier One - Network Virtualization Everywhere - * Copyright (C) 2011-2016 ZeroTier, Inc. https://www.zerotier.com/ - * - * This program is free software: you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It can be used to set up trusted paths, blacklist physical paths, set up physical path hints for certain nodes, and define trusted upstream devices (federated roots). In a large deployment it can be deployed using a tool like Puppet, Chef, SaltStack, etc. to set a uniform configuration across systems. It's a JSON format file that can also be edited and rewritten by ZeroTier One itself, so ensure that proper JSON formatting is used. - -Settings available in `local.conf` (this is not valid JSON, and JSON does not allow comments): - -```javascript -{ - "physical": { /* Settings that apply to physical L2/L3 network paths. */ - "NETWORK/bits": { /* Network e.g. 10.0.0.0/24 or fd00::/32 */ - "blacklist": true|false, /* If true, blacklist this path for all ZeroTier traffic */ - "trustedPathId": 0|!0 /* If present and nonzero, define this as a trusted path (see below) */ - } /* ,... additional networks */ - }, - "virtual": { /* Settings applied to ZeroTier virtual network devices (VL1) */ - "##########": { /* 10-digit ZeroTier address */ - "try": [ "IP/port"/*,...*/ ], /* Hints on where to reach this peer if no upstreams/roots are online */ - "blacklist": [ "NETWORK/bits"/*,...*/ ] /* Blacklist a physical path for only this peer. */ - } - }, - "settings": { /* Other global settings */ - "primaryPort": 0-65535, /* If set, override default port of 9993 and any command line port */ - "portMappingEnabled": true|false, /* If true (the default), try to use uPnP or NAT-PMP to map ports */ - "softwareUpdate": "apply"|"download"|"disable", /* Automatically apply updates, just download, or disable built-in software updates */ - "softwareUpdateChannel": "release"|"beta", /* Software update channel */ - "softwareUpdateDist": true|false, /* If true, distribute software updates (only really useful to ZeroTier, Inc. itself, default is false) */ - "interfacePrefixBlacklist": [ "XXX",... ], /* Array of interface name prefixes (e.g. eth for eth#) to blacklist for ZT traffic */ - "allowManagementFrom": "NETWORK/bits"|null /* If non-NULL, allow JSON/HTTP management from this IP network.

This provides a performance boost but sacrifices all ZeroTier's security features when communicating over this path. Only use this if you know what you are doing and really need the performance! To set up a trusted path, all devices using it *MUST* have the *same trusted path ID* for the same network. Trusted path IDs are arbitrary positive non-zero integers. For example a group of devices on a LAN with IPs in 10.0.0.0/24 could use it as a fast trusted path if they all had the same trusted path ID of "25" defined for that network. - * **relayPolicy**: Under what circumstances should this device relay traffic for other devices? The default is TRUSTED, meaning that we'll only relay for devices we know to be members of a network we have joined. NEVER is the default on mobile devices (iOS/Android) and tells us to never relay traffic. ALWAYS is usually only set for upstreams and roots, allowing them to act as promiscuous relays for anyone who desires it. - -An example `local.conf`: - -```javascript -{ - "physical": { - "10.0.0.0/24": { - "blacklist": true - }, - "10.10.10.0/24": { - "trustedPathId": 101010024 - }, - }, - "virtual": { - "feedbeef12": { - "role": "UPSTREAM", - "try": [ "10.10.20.1/9993" ], - "blacklist": [ "192.168.0.0/24" ] - } - }, - "settings": { - "softwareUpdate": "apply", - "softwraeUpdateChannel": "release" - } -} -``` - -### Network Virtualization Service API - -The JSON API supports GET, POST/PUT, and DELETE. PUT is treated as a synonym for POST. Other methods including HEAD are not supported. - -Values POSTed to the JSON API are *extremely* type sensitive. Things *must* be of the indicated type, otherwise they will be ignored or will generate an error. Anything quoted is a string so booleans and integers must lack quotes. Booleans must be *true* or *false* and nothing else. Integers cannot contain decimal points or they are floats (and vice versa). If something seems to be getting ignored or set to a strange value, or if you receive errors, check the type of all JSON fields you are submitting against the types listed below. Unrecognized fields in JSON objects are also ignored. - -API requests must be authenticated via an authentication token. ZeroTier One saves this token in the *authtoken.secret* file in its working directory. This token may be supplied via the *auth* URL parameter (e.g. '?auth=...') or via the *X-ZT1-Auth* HTTP request header. Static UI pages are the only thing the server will allow without authentication. - -A *jsonp* URL argument may be supplied to request JSONP encapsulation. A JSONP response is sent as a script with its JSON response payload wrapped in a call to the function name supplied as the argument to *jsonp*. - -#### /status - - * Purpose: Get running node status and addressing info - * Methods: GET - * Returns: { object } - -| Field | Type | Description | Writable | -| --------------------- | ------------- | ------------------------------------------------- | -------- | -| address | string | 10-digit hex ZeroTier address of this node | no | -| publicIdentity | string | This node's ZeroTier identity.public | no | -| worldId | integer | ZeroTier world ID (never changes except for test) | no | -| worldTimestamp | integer | Timestamp of most recent world definition | no | -| online | boolean | If true at least one upstream peer is reachable | no | -| tcpFallbackActive | boolean | If true we are using slow TCP fallback | no | -| relayPolicy | string | Relay policy: ALWAYS, TRUSTED, or NEVER | no | -| versionMajor | integer | Software major version | no | -| versionMinor | integer | Software minor version | no | -| versionRev | integer | Software revision | no | -| version | string | major.minor.revision | no | -| clock | integer | Current system clock at node (ms since epoch) | no | - -#### /network - - * Purpose: Get all network memberships - * Methods: GET - * Returns: [ {object}, ... ] - -Getting /network returns an array of all networks that this node has joined.

This page is being served from a Docker container with its own private TCP/IP microservice.

- -

-It's connected to a virtual network, but if you "docker exec" into it and look around you won't find any special devices. No special privileges or configuration changes on the Docker host were needed. Everything is completely "stock" and completely self-contained. -

- -

-There's nothing special about the web server. It's just Apache. There's nothing special about the Linux image. It's based on a regular Fedora Docker base image. Other than Apache, the only thing this image contains is the ZeroTier network containers microservice and dynamic library. -

- -

-When Apache is run, our launcher script configures it to load a special dynamic library. This library intercepts calls to the Linux C networking API, redirecting network I/O to our private network stack microservice instead of the standard Linux kernel network path. This microservice takes care of the rest, automatically encapsulating traffic and sending it over the virtual network instead of the physical. -

- -

-It's a bit like how networking would work on a microkernel: modular, composable, portable, and independent. -

- -

-SDK allows a Docker (or LXC, CoreOS/rkt, runc, OpenVZ, SmartOS/Triton, bocker, or even just bare metal Linux) system to connect to virtual networks without requiring any special permissions or special configuration on the host node. Processes inside the container don't even need to run with root permissions. It's 100% user-space, making it ideal for multi-tenant deployments or any other situation where modifying the configuration of the host node is impossible or just inconvenient. -

- -

-Once properly tuned and optimized, SDK also has the potential to be much faster than tun/tap or pcap based network overlays. It imposes only a single context switch from application/service to virtual network microservice as opposed to at least four for tun/tap and pcap-based solutions, since the latter require two trips through the kernel network stack. We believe it may be possible to approach or even equal the performance of VXLAN/IPSec or other fully kernel-mode configurations, but with the ease and total independence of a fully container-based solution. -

- -

-We created this container image to show you a preview of one of the projects we've been working on at ZeroTier. We still have a good deal of packaging, testing, and performance optimization work to do before SDK will be ready for a real public beta release. Follow the blog or @zerotier for updates and announcements. -

- -

-P.S. If you want to use ZeroTier in Docker today, you can do it with the same ZeroTier One endpoint service you're using to access this network. The only catch is that you have to launch your containers with "--device=/dev/net/tun --cap-add=NET_ADMIN". SDK eliminates the need for these special options. -
