1.【需求描述】： 支持内核态和用户态堆内存非法访问检测，包括：越界访问、double free、释放后使用；支持libc常用高频函数内存检测；支持安全函数内存检测；读写检测可配可裁剪。 2.【方案描述】： L0 ~ L1: (1).影子内存映射与标记 (2).编译器使能-fsanitize=kernel-address 自动插桩检测点 (3).实时校验影子内存的合法性； (4).错误访问打印回溯栈 BREAKING CHANGE: 新增支持API: LOS_LmsCheckPoolAdd使能检测指定内存池 LOS_LmsCheckPoolDel不检测指定内存池 LOS_LmsAddrProtect为指定内存段上锁，不允许访问 LOS_LmsAddrDisableProtect去能指定内存段的访问保护 Close #I4HYAV Signed-off-by: LiteOS2021 <dinglu@huawei.com> Change-Id: Id8e5c890656da9edc4a22227e6a3c32205c024ce
