As discussed at the Linux Security Summit, I'm resubmitting this
code. As an LSM, it has coherent policy around expanding specific DAC
behaviors. There is no need for it to be a full-blown MAC, since it is
not intended to be one, but rather to be a simplified expansion to DAC,
with system-wide knobs. See the specific patches for details...

This version only contains the ptrace restrictions, since a path has
been cleared for that (thanks Roland). The link restriction discussion
can continue separately. In the meantime, I will carry it as a patch here:

Thanks,

-Kees
