Hi all,
I have been trying to intercept all the system calls on my system, and want to do it for certain processes only.
I tried playing around with the code in entry_32.S in the kernel sources. If I try to change the value of sys_call_table, the kernel crashes while trying to start the init process. This also happens if I try to move the same value into sys_call_vector again..
i.e, something like

movl $sys_call_table, %ecx
movl %ecx, $sys_call_table
call *sys_call_table(,%eax,4)

Any suggestions ?
