System calls in Ubuntu

[jivesoul]

Hey everyone.

I am trying to work with system calls in Ubuntu 6.06. Kernel is 2.6.15-27-386.

I have found a few guides around the internet that discuss intercepting system calls in a kernel, but I cannot get any of them to work. Most discuss editing entry.S, but I cannot find this file anywhere. Others discuss using sys_call_table, but it seems like it is no longer exported by the kernel.

Does anyone know how to use system calls in Ubuntu? I need to be able to pass data to a kernel module, and a system call would really help.

Thanks.

If you need to exchange data with a kernel module, an entry in /dev would probably be a better bet. System call numbers can change, but it's not likely that /dev/my_module would ever be claimed by the kernel developers.
