In linux kernel 2.6.x, what should we do to intercept
system calls? When I used sys_call_table from a
module, it returned the following error 'undefined
variable sys_call_table'. What is the way to export
system call table in kernel 2.6.x?
Thanks,
selva

That's generally very deprecated.
What problem are you trying to solve by intercepting system calls? There
may very well be some other way to achieve what you're trying to do...

Hello,
I want to save the system call parameters in a
table. I want to do this from the kernel module. For
that, I want to replace the already existing system
call handler by my own. Are there any other mechanisms
for doing this without exporting system call table? If
it is then plz suggest any one of them?
Thanks,
selva

subsystem that is already there ?
