Subject: [PATCH AUTOSEL 4.19 77/81] net/tls: fix the IV leaks
Date: Tue,  7 May 2019 01:35:48 -0400	[thread overview]
Message-ID: <20190507053554.30848-77-sashal@kernel.org> (raw)
In-Reply-To: <20190507053554.30848-1-sashal@kernel.org>

From: Jakub Kicinski <jakub.kicinski@netronome•com>

[ Upstream commit 5a03bc73abed6ae196c15e9950afde19d48be12c ]

Commit f66de3ee2c16 ("net/tls: Split conf to rx + tx") made
freeing of IV and record sequence number conditional to SW
path only, but commit e8f69799810c ("net/tls: Add generic NIC
offload infrastructure") also allocates that state for the
device offload configuration.  Remember to free it.

Fixes: e8f69799810c ("net/tls: Add generic NIC offload infrastructure")
