Subject: [PATCH v7 13/17] KEYS: link secondary_trusted_keys to machine trusted keys
Date: Mon, 15 Nov 2021 19:15:41 -0500 [thread overview]
Message-ID: <20211116001545.2639333-14-eric.snowberg@oracle.com> (raw)
In-Reply-To: <20211116001545.2639333-1-eric.snowberg@oracle.com>
Allow the .machine keyring to be linked to the secondary_trusted_keys.
After the link is created, keys contained in the .machine keyring will
automatically be searched when searching secondary_trusted_keys.
Signed-off-by: Eric Snowberg <eric.snowberg@oracle.com>

v3: Initial version
v4: Unmodified from v3
