Subject: [RFC PATCH v2 02/11] nvme-keyring: Add a missing key_put() call to nvme_tls_key_lookup()
Date: Tue,  3 Nov 2026 05:02:07 +0200	[thread overview]
Message-ID: <20261103030226.2685251-3-jarkko@kernel.org> (raw)
In-Reply-To: <20261103030226.2685251-1-jarkko@kernel.org>

Call key_put() before returning -EKEYREVOKED, as the reference count gets
incremented by key_lookup().

Cc: stable@vger.kernel.org # v6.12+
Fixes: 5bc46b49c828 ("nvme-tcp: check for invalidated or revoked key")
Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>
