From 150f37cc594de34cda146cd71a325cc48ec7c72b Mon Sep 17 00:00:00 2001 From: "Bjoern A. Zeeb" Date: Wed, 22 Apr 2009 08:22:16 +0000 Subject: MFC r191305: Back out r186308 (r191014 in stable/7): In case of AF_LINK, which the kernel still returns for an RTAX_GATEWAY as an empty sockaddr_dl in the classic tun case: copying the address into the message payload, but not the RTA_GATEWAY flag results in rt_xaddrs() in the kernel tripping over that and parsing the next attribute set with a flag, i.e. RTA_NETMASK, with the gateway address, resulting in bogus route entry.
