It sets the fields in the proc structure which defines the stack protection. >I'm not sure what point there would be in per-thread >control; if any one thread in an address space is exploitable, >the whole address space is potentially corruptible. It's different because mprotect() works on the process. Using mprotect requires you to run mprotect on all process stacks (as long as they are created by the library). I'm not sure that the kernel has sufficient information to figure that out.
