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_v_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: b71bb6f924fe ("batman-adv: add B.A.T.M.A.N.

The following commit has been merged in the master branch: commit 36dc621ceca1be3ec885aeade5fdafbbcc452a6d Author: Sven Eckelmann <sven(a)narfation.org> Date: Fri Jun 1 19:24:23 2018 +0200 batman-adv: Fix debugfs path for renamed hardif batman-adv is creating special debugfs directories in the init net_namespace for each valid hard-interface (net_device). But it is possible to rename a net_device to a completely different name then the original one. It can therefore happen that a user registers a new net_device which gets the name "wlan0" assigned by default. batman-adv is also adding a new directory under $debugfs/batman-adv/ with the name "wlan0". The user then decides to rename this device to "wl_pri" and registers a different device. The kernel may now decide to use the name "wlan0" again for this new device. batman-adv will detect it as a valid net_device and tries to create a directory with the name "wlan0" under $debugfs/batman-adv/. But there already exists one with this name under this path and thus this fails. batman-adv will detect a problem and rollback the registering of this device. batman-adv must therefore take care of renaming the debugfs directories for hard-interfaces whenever it detects such a net_device rename.
