From 870c3151382c980590d4d609babf3b0243e7db93 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 17 Oct 2014 09:17:20 -0700 Subject: ipv6: introduce tcp_v6_iif() Commit 971f10eca186 ("tcp: better TCP_SKB_CB layout to reduce cache line misses") added a regression for SO_BINDTODEVICE on IPv6. This is because we still use inet6_iif() which expects that IP6 control block is still at the beginning of skb->cb[] This patch adds tcp_v6_iif() helper and uses it where necessary. Because __inet6_lookup_skb() is used by TCP and DCCP, we add an iif parameter to it.
