Apple's XNU kernel supports native TUN interface called
utunfrom iOS 4.1 and OS X 10.7 Lion. It is a bit different from the standard TUN interface, which is similar with the OpenBSD one.This patch adds necessary code to build up the utun interface and set
session->use_pi = 2for manipulating TUN devices just like OpenBSD. It is tested to work on OS X 10.9 Mavericks.References:
