Subject: [PATCH AUTOSEL 5.14 11/25] ceph: fix memory leak on decode error in ceph_handle_caps
Date: Mon, 13 Sep 2021 18:33:25 -0400 [thread overview]
Message-ID: <20210913223339.435347-11-sashal@kernel.org> (raw)
In-Reply-To: <20210913223339.435347-1-sashal@kernel.org>
From: Jeff Layton <jlayton@kernel.org>
[ Upstream commit 2ad32cf09bd28a21e6ad1595355a023ed631b529 ]
If we hit a decoding error late in the frame, then we might exit the
function without putting the pool_ns string. Ensure that we always put
that reference on the way out of the function.
