From 6057fd78a8dcce6269f029b967051d5a2e9b0895 Mon Sep 17 00:00:00 2001 From: Brian Haley Date: Fri, 28 May 2010 23:02:35 -0700 Subject: IPv6: fix Mobile IPv6 regression Commit f4f914b5 (net: ipv6 bind to device issue) caused a regression with Mobile IPv6 when it changed the meaning of fl->oif to become a strict requirement of the route lookup. Instead, only force strict mode when sk->sk_bound_dev_if is set on the calling socket, getting the intended behavior and fixing the regression.
