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: http://git.kernel.org/?p=linux/kernel/git/kees/linux.git;a=shortlog;h=refs/heads/yama Thanks, -Kees
