Subject: [PATCH 3/4] crypto: testmgr - disallow plain ghash in FIPS mode
Date: Tue,  8 Nov 2022 15:20:24 +0100	[thread overview]
Message-ID: <20221108142025.13461-4-nstange@suse.de> (raw)
In-Reply-To: <20221108142025.13461-1-nstange@suse.de>

ghash may be used only as part of the gcm(aes) construction in FIPS
mode. Since commit d6097b8d5d55 ("crypto: api - allow algs only in specific
constructions in FIPS mode") there's support for using spawns which by
itself are marked as non-approved from approved template instantiations.
So simply mark plain ghash as non-approved in testmgr to block any attempts
of direct instantiations in FIPS mode.
