Please keep in mind that hooking a system call is very bad and error prone.

Thanks for advice !
I am using the LSM framework even though it need recompiling the kernel.
But I will also give a try to the kernelroll module.
Modifying sys_call_table is easier to get error but it can get more freedom
than LSM framework which could only hook on limit hooking points.

Hi,
Thank all of you for helping me with problem!
I don't want to modify my kernel source so I am trying to learn to use LSM
security hook even though it seems that it couldn't hook all the system
calls, I think it should be enough for me.
Thanks again!

waining:'register_security' undefined, then I check security/security.c
and found out that register_security is not exported ! So if I want to use
this function ,I must hack kernel by exporting and recompiling kernel which
is
