Apple checks EUID==0 on ioctl(/dev/pf), whereas OpenBSD and FreeBSD only check permissions on open(/dev/pf). This means that on OS X, it is not possible to open /dev/pf, drop privileges, and send an ioctl to the file descriptor opened earlier with EUID==0. It also means Apple broke the Unix way of dealing with device nodes - why are there file permissions on /dev/pf when they later enforce EUID==0 on use, thereby breaking basic Unix mechanisms? Work around this by disallowing -u with pf proxyspecs and by not automatically dropping to nobody on Mac OS X. Issue: #65 Reported by: Vladimir Marteev
