=> do_syscall_64 => entry_SYSCALL_64_after_hwframe 对于不同的体系架构,进行函数调用时使用的传参规则并不相同,所以在使用kprobe提取函数参数时使用的方式也不 相同,为了解决这一问题,内核引入了一个patch:a1303af5d79eb13a658633a9fb0ce3aed0f7decf解决了这一问题, 使用argX来代表参数,比如上面的这个file...
*/SYSCALL_DEFINE1(exit_group,int,error_code){do_group_exit((error_code&0xff)<<8);/* NOTREACHED */return0;} do_exit_group流程 do_group_exit()函数杀死属于current线程组的所有进程。它接受进程终止代码作为参数,进程终止代号可能是系统调用exit_group()指定的一个值,也可能是内核提供的一个错误代号...

Hi, First, I must warn you that I am currently working on 20130109 ltp version (we do not have time at work to update to latest versions...). We are currently porting Linux to our processor architecture, and we need to have tests running...
