hi all,
i have kernel hacking assignments as my operating systems course ...i am trying to register a simple system call on ubuntu that simply prints with kprint stmt
Code:
#include <linux/kernel.h>
asmlinkage long sys_cs2456_test(int arg0)
{
printk(" Hello World !");
printk("--syscall arg %d", arg0);
return((long) arg0);
}
i register this call in the following files ... following their syntax strictly:
arch/x86/kernel/syscall_table_32.S
and
arch/x86/include/asm/unistd_32.h
i also update the Makefile for linux with the folder for my sys call ... when i make the kernel it generates the object file but when i test the system call in user space it gives me an error that my system call is not defined.
help!!!!!!!!!!!!!!
