Subject: [PATCH v3 11/14] KEYS: link secondary_trusted_keys to mok trusted keys
Date: Wed, 11 Aug 2021 22:18:52 -0400 [thread overview]
Message-ID: <20210812021855.3083178-12-eric.snowberg@oracle.com> (raw)
In-Reply-To: <20210812021855.3083178-1-eric.snowberg@oracle.com>
Allow the .mok keyring to be linked to the secondary_trusted_keys. After
the link is created, keys contained in the .mok keyring will automatically
be searched when searching secondary_trusted_keys.
