Subject: [PATCH AUTOSEL 4.9 08/25] mac80211: fix unaligned access in mesh table hash function
Date: Tue, 7 May 2019 01:41:05 -0400 [thread overview]
Message-ID: <20190507054123.32514-8-sashal@kernel.org> (raw)
In-Reply-To: <20190507054123.32514-1-sashal@kernel.org>
From: Felix Fietkau <nbd@nbd.name>
[ Upstream commit 40586e3fc400c00c11151804dcdc93f8c831c808 ]
The pointer to the last four bytes of the address is not guaranteed to be
aligned, so we need to use __get_unaligned_cpu32 here
