From fa3a03da549a889fc9dbc0d3c5908eb7882cac8f Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sun, 7 Jul 2019 22:15:13 +0200 Subject: 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.
