> If you want to have fun, try calling revoke(2) on character devices that are not TTYs. I remember fixing a bug in FreeBSD once, where you could make the system panic by calling that function on /dev/bpf.

IIRC there's a lot of problems with revoke(2) on anything that's not a tty device, so on OpenBSD revoke(2) returns ENOTTY in those cases.



This was discovered earlier on during pledge(2) development.
