Subject: [PATCH net-next 2/2] selftests: tls: add a test for timeo vs lock
Date: Wed, 20 Jul 2022 13:37:01 -0700 [thread overview]
Message-ID: <20220720203701.2179034-2-kuba@kernel.org> (raw)
In-Reply-To: <20220720203701.2179034-1-kuba@kernel.org>
Add a test for recv timeout. Place it in the tls_err
group, so it only runs for TLS 1.2 and 1.3 but not
for every AEAD out there.
