| |
hi i am doing a project on a very simple system call interception module. the module is supposed to return the uid of the user who made the call to the syscall. i m trying to do it thus:
//in the kernel module asmlinkage long my_syscall(arg1,arg2) { sprintf(buffer, "%s%s%i", arg1,arg2,current->uid); //this buffer is later read. return original_syscall(arg1,arg2); }
the problem is that the uid returned is always -1. i found you had a similar problem very long back and had posted a msg on a mailing list.
could you suggest a way out please. thanx -kt
