-Subject: [PATCH] Bridge: Fix ipv6 mc snooping if bridge has no ipv6 address
-
-The bridge is falsly dropping ipv6 mulitcast packets if there is:
- 1. No ipv6 address assigned on the brigde.
- 2. No external mld querier present.
- 3. The internal querier enabled.
-
-When the bridge fails to build mld queries, because it has no
-ipv6 address, it slilently returns, but keeps the local querier enabled.
-This specific case causes confusing packet loss.
-
-Ipv6 multicast snooping can only work if:
- a) An external querier is present
- OR
- b) The bridge has an ipv6 address an is capable of sending own queries
-
-Otherwise it has to forward/flood the ipv6 multicast traffic,
-because snooping cannot work.
-
-This patch fixes the issue by adding a flag to the bridge struct that
-indicates that there is currently no ipv6 address assinged to the bridge
-and returns a false state for the local querier in
-__br_multicast_querier_exists().
-
-Special thanks to Linus Lüssing.
-
-Fixes: d1d81d4c3dd8 ("bridge: check return value of ipv6_dev_get_saddr()")
