4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Artur Molchanov <arturmolcha...@gmail.com>
commit 14221cc45caad2fcab3a8543234bb7eda9b540d5 upstream.
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")
