how can I make system_call_table address to writable so that one can change to >>customized system call.
Like this:
unsigned int level; pte_t *pte = lookup_address(sys_call_table, &level); if(pte->pte &~ _PAGE_RW) pte->pte |= _PAGE_RW; An awesome example of pretty much what you're trying to do can be found here: https://github.com/fpletz/kernelroll Enjoy :D
