[PATCH 6/6] bridge: netfilter: Fix dropping packets that moving through bridge interface

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2017-01-05 11:19:53
Also in: netfilter-devel
Subsystem: ethernet bridge, netfilter, networking [general], the rest · Maintainers: Nikolay Aleksandrov, Ido Schimmel, Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

From: Artur Molchanov <redacted>

Problem:
br_nf_pre_routing_finish() calls itself instead of
br_nf_pre_routing_finish_bridge(). Due to this bug reverse path filter drops
packets that go through bridge interface.

User impact:
Local docker containers with bridge network can not communicate with each
other.

Fixes: c5136b15ea36 ("netfilter: bridge: add and use br_nf_hook_thresh")
