commit d1de7f7aa316d6f7b3268f61afa88f5d2c1a5db5 Author: Sven Eckelmann sven@narfation.org Date: Sun Jul 7 22:19:22 2019 +0200

batman-adv: Fix netlink dumping of all mcast_flags buckets

The bucket variable is only updated outside the loop over the mcast_flags buckets. It will only be updated during a dumping run when the dumping has to be interrupted and a new message has to be started.

This could result in repeated or missing entries when the multicast flags are dumped to userspace.

Fixes: 06c82b7b15b1 ("batman-adv: Add inconsistent multicast netlink dump detection") Signed-off-by: Sven Eckelmann sven@narfation.org
