Guard CF address of check-function pointer:_guard_check_icall的地址(见图4)。在Windows 10预览版中,当PE文件加载时,_guard_check_icall将被修改并指向nt!LdrpValidateUserCallTarget。 Guard CF function table:函数的相对虚拟地址(RVA)列表的指针,其包含了程序的代码。每个函数的RVA将转化为CFGBitmap中的“1...

图19 – 在这个函数中,它将修改_guard_check_icall的值指向LdrpValidateUserCallTarget 7. 在所有的准备都完成后,如果间接调用的目标地址相关的位在CFGBitmap中不是“1”,将触发CFG。进程将采取行动处理这个异常。处理函数是RtlpHandleInvalidUserCallTarget。这个函数使用间接调用的目标为唯一的参数。函数的主要逻辑如...

Right now, the tests intests/ui/check-cfg/contain every built-in config known to the compiler, like so: this means they have to be updated each time a new builtin cfg is added, which is annoying, prone to merge conflicts, and distracts from what the test is actually doing. Also, it...
