Is there a way to replace a system call dynamically within a module?
Naive approach of putting something like:
asmlinkage int sys_getpid(void)
{
printk(KERN_INFO "my getpid() for <%s>\n", current->comm);
return current->pid;
}
of course, did not work, although it did not generate any errors and
loaded ok, and even /proc/ksyms showed sys_getpid() as exported by this
trivial module.
So, if the above is not the way -- is there a proper way at all?
Thanks,
Tigran.
