Thanks! I've re-enabled selinux on syzbot: https://github.com/google/syzkaller/commit/196410e4f5665d4d2bf6c818d06f1c8d03cfa8cc Now we will have instances with apparmor and with selinux.Any chance we could get a Smack instance as well?Hi Casey, Sure! Provided you want to fix bugs ;) I've setup an instance with smack enabled: https://github.com/google/syzkaller/commit/0bb7a7eb8e0958c6fbe2d69615b9fae4af88c8ee
But just doing default things does not seem to find much. I guess common paths through the hooks are well exercised already. So perhaps if we do more non-trivial things, it can find more stuff. But what are they? Adding/changing/removing xattr's? Which? What are the values? Changing security contexts? How? What else? selinux has own filesystem and we should touch some files there: https://github.com/google/syzkaller/blob/master/sys/linux/selinux.txt But we don't anything similar for other modules.
