Subject: bridge: netfilter: Fix dropping packets that moving through bridge interface
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=14221cc45caad2fcab3a8543234bb7eda9b540d5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bridge: netfilter: Fix dropping packets that moving through bridge interface

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.
