Subject: [PATCH 4/6] crypto: testmgr - disallow plain cbcmac(aes) in FIPS mode
Date: Wed, 21 Dec 2022 23:41:09 +0100	[thread overview]
Message-ID: <20221221224111.19254-5-vdronov@redhat.com> (raw)
In-Reply-To: <20221221224111.19254-1-vdronov@redhat.com>

From: Nicolai Stange <nstange@suse.de>

cbcmac(aes) may be used only as part of the ccm(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 cbcmac(aes) as non-approved in testmgr to block any
attempts of direct instantiations in FIPS mode.
