From 16f37cbd72984d3e25a2324dee9f4d099acfee00 Mon Sep 17 00:00:00 2001 From: "Bjoern A. Zeeb" Date: Mon, 20 Apr 2009 11:22:51 +0000 Subject: Back out r186308: 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.
