+Subject: [PATCH] batman-adv: Fix bat_ogm_iv best gw refcnt after netlink dump
+
+A reference for the best gateway is taken when the list of gateways in the
+mesh is sent via netlink. This is necessary to check whether the currently
+dumped entry is the currently selected gateway or not. This information is
+then transferred as flag BATADV_ATTR_FLAG_BEST.
+
+After the comparison of the current entry is done,
+batadv_iv_gw_dump_entry() has to decrease the reference counter again.
+Otherwise the reference will be held and thus prevents a proper shutdown of
+the batman-adv interfaces (and some of the interfaces enslaved in it).
+
+Fixes: fa3228924152 ("batman-adv: add B.A.T.M.A.N. IV bat_gw_dump implementations")
