M22现场下发一条策略：“Lantern_vpn_ test”，策略详情如图：

策略于2024-06-27 09:52:24已经限定Source IP Address，但是在查询Security Events（2024-06-27 10:33:26 to 2024-06-27 10:45:53）日志的时候发现，日志展示的client ip出现一些除了Source IP Address条件限定外的IP Address，如图：

在此期间除了客户修改了策略条件外，无其他操作，修改前后策略对比：

[~liuchang]  写个maat的单测复现一下，用maat_cmd_set_line接口构造：
session属性： src IP_X -> dst IP
测试流程：
# 规则 rule1: src IP_Y & dst IP
# maat_scan(session.src_ip_Y), maat_scan(session.dst_Ip) 
# EXPECT 不命中
# 新建规则 app1（compile）: dst IP
# 修改rule1 : src IP_Y & app1
# reset maat_state
# maat_scan(session.src_ip_X), maat_scan(session.dst_Ip)
# EXPECT不命中

*用户操作*
根据audit log，{*}10:33~10:52{*}之间，对应策略存在如下修改操作：
!image-2024-06-28-17-24-50-136.png|width=247,height=560!!image-2024-06-28-17-25-00-177.png|width=277,height=565!
* v12 策略条件 source IP + destination IP
* v13 策略条件从source IP + destination IP，变更为source IP + APPID
* v14 策略失效
* v15 策略生效
* v16 策略失效
* v17 策略生效
*异常日志*
* 从现场导出Security Event Log，查询条件为“reveive time：10:34-10:52， start time 10:31-10:33” 共计13752条日志，其中ClientIP非策略条件中的11555条（{*}异常日志{*}）
** 异常命中的会话，会话持续时间普遍超过60s，少量会话持续时间较短（<10s）
** *92台Sled均出现异常日志*
* 按sled_ip==10.161.12.10过滤，异常命中会话出现的end time（策略条件为Deny，该时间通常为命中策略的时刻）时段为{*}10:33:28~10:46:27{*}，对应maat的日志[^firewall.cm.maat.2024-06-27]
*功能端日志*
* 查询10.161.12.10设备的maat规则更新日志，10:33:28~10:46:27之间，存在6次增量，每次加载的entries在3~6条之间
** 10:41:39的增量加载后，SECURITY_COMPILE_PLUGIN的rule_count从130变更为129
** 10:41:52的增量加载后，又从129变回130
!image-2024-06-27-20-07-09-538.png|width=875,height=298!
 
根据现场收集的信息，本issue中的误命中，发生时段为用户界面多次修改策略的过程。推测在该过程中，功能端执行策略时，策略条件退化为APPID。

maat单测用例未复现，测试流程：
session属性： src IP 45.112.178.18 -> dst IP 2.2.2.2
# 规则 rule1: src IP 103.89.49.6 & dst IP 2.2.2.2
# maat_scan_ipv4("45.112.178.18"), maat_scan_ipv4("2.2.2.2") 
# EXPECT 不命中，{*}实际不命中{*}
# 新建规则 app1（compile）: dst IP{*}（只新建了app_id表的一个group）{*}
# 修改rule1 : src 103.89.49.6 & app1（group）
# reset maat_state
# maat_scan_ipv4("45.112.178.18"), maat_scan_group(app1.group_id)

在信息港44.3环境模拟现场操作情况，操作一条生效的，ID为212的安全策略：
1. 修改策略条件：修改前条件source+destination，修改后条件source+application，产生如下图的MAA_UPDATE_STATUS，修改操作每个表的每个操作版本号+1（删除+1，新增+1），下图涉及两张表，所以本次修改操作，MAAT_VERSION+4
!image-2024-06-28-15-41-40-712.png!
2. 停用策略，MAAT_VERSION+2（两张表）
!image-2024-06-28-15-41-10-125.png!
3. 启用策略：MAAT_VERSION+2（两张表）

补充测试：MAAT单测中模拟CM的行为操作策略，修改策略条件和启停策略，未复现bug

* 京版网关环境稳定复现本BUG，误命中的持续时间约4分钟
** 策略ID=5211 2024-06-28 20:03:39~20:07:33存在误命中
*  京版网关环境复现步骤：
** 创建策略条件：Source IP+Destination IP, 生效策略

** 从dump的策略详情可以看出，{color:#ff0000}*策略修改前后ATTR_SOURCE_IP对应的cluster ID由0变更为1*{color}，在这种场景下maat添加自测试用例能复现误命中问题：用例如下：
*** 添加策略
**** 添加策略条件 ATTR_SOURCE_IP(1.1.1.1)  cluster ID=0
**** 添加策略条件 ATTR_DESTINATION_IP(2.2.2.2) cluster ID=1 
**** Scan Source IP(3.3.3.3)
**** scan Destination IP (2.2.2.2) 
*** 修改策略
**** 删除策略条件 ATTR_SOURCE_IP  cluster ID=0
**** 删除策略条件 ATTR_DESTINATION_IP cluster ID=1 
**** 添加策略条件 ATTR_SOURCE_IP  cluster ID=1
**** 添加策略条件 ATTR_APP_ID(group=1000) cluster ID=0
**** Scan Application(group_id=1000)
* 原因：
** maat扫描命中group ID后将clause ID记录在maat_state中，策略更新时clause ID发生变化时没有更新maat_state中的clause ID，故发生误命中。
*** 扫描source IP + Destination IP后配置更新（clause ID发生变化），maat_state中clause ID未更新，接着扫描Application时实际生效条件变为Destination IP + Application
