We need to be careful and always zero the whole br_ip struct when it is
used for matching since the rhashtable change. This patch fixes all the
places which didn't properly clear it which in turn might've caused
mismatches.
Thanks for the great bug report with reproducing steps and bisection.
Steps to reproduce (from the bug report):
ip link add br0 type bridge mcast_querier 1
ip link set br0 up
ip link add v2 type veth peer name v3
ip link set v2 master br0
ip link set v2 up
ip link set v3 up
ip addr add 3.0.0.2/24 dev v3
ip netns add test
ip link add v1 type veth peer name v1 netns test
ip link set v1 master br0
ip link set v1 up
ip -n test link set v1 up
ip -n test addr add 3.0.0.1/24 dev v1
# Multicast receiver
ip netns exec test socat
UDP4-RECVFROM:5588,ip-add-membership=224.224.224.224:3.0.0.1,fork -
# Multicast sender
echo hello | nc -u -s 3.0.0.2 224.224.224.224 5588
