Subject: [PATCH AUTOSEL 5.2 018/249] batman-adv: fix for leaked TVLV handler.
Date: Mon, 15 Jul 2019 09:31:59 -0400 [thread overview]
Message-ID: <20190715133550.1772-18-sashal@kernel.org> (raw)
In-Reply-To: <20190715133550.1772-1-sashal@kernel.org>
From: Jeremy Sowden <jeremy@azazel.net>
[ Upstream commit 17f78dd1bd624a4dd78ed5db3284a63ee807fcc3 ]
A handler for BATADV_TVLV_ROAM was being registered when the
translation-table was initialized, but not unregistered when the
translation-table was freed. Unregister it.
Fixes: 122edaa05940 ("batman-adv: tvlv - convert roaming adv packet to use tvlv unicast packets")
