We are trying to write a module that does it's own accounting of processes as they are created and deleted. We have an extremely ugly hack of taking care of process creation (wrap fork() and clone() in a syscall wrapper, as that's the only way processes can be created).
However, doing the same for exit() doesn't work, because processes don't have to call exit() to die, but can be killed any of number of ways, and go straight to the do_exit() code.
I would imagine one would hook a void * function that takes some sort of defined argument, perhaps a pointer to the task_struct (as it will be called in do_exit, it would seem locking shouldn't be an issue) and what the function is allowed to do would be defined.
Would people be for/against an interface that allows for modules to register functions that can be called on process creation/deletion. It would help us avoid the hacks, such as I described, and I imagine could have benefit others.
thanks,
shaya
