From: Brian Haley Date: Sat, 29 May 2010 06:02:35 +0000 (-0700) Subject: IPv6: fix Mobile IPv6 regression X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6057fd78a8dcce6269f029b967051d5a2e9b0895;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
