The real question here is why use lsm at all? lsm sounds like the wrong
set of hooks for something like this. If you look at the hooks they are
clearly for access control handling, which this isn't at all. I bet
your code would be a lot simpler if you just hooked into the right places
directly. and made it controllable by selinux or $lsm.
