Subject: [PATCH] Allow hmac(sha512) for unpriviledged users
Date: Sat, 3 Oct 2026 10:03:02 -0600 [thread overview]
Message-ID: <20261003160302.3000325-1-jforbes@fedoraproject.org> (raw)
By default users cannot run sha512hmac with the current set up. This
is problematic because our kernel builds call this for FIPS compliance.
Rather than have anyone turn off af_alg_restrict all together, let's
allow a common use case.
