Cover letter [PATCH 0/2] crypto: disallow non-approved algs in fips mode
At present, nothing is preventing the use of non-approved algorithms in fips mode. I was initially working on a patch to make it easier for all fips-approved algs to be tested using tcrypt, and realized the changes I was making could also be used to prevent non-approved algs in fips mode. Any approved alg *must* have self-tests, and thus have an entry in testmgr.c's alg_test_descs[]. By adding a fips flag to these entries, we can simply reject all algs that don't have this flag when in fips mode by skipping their self-tests and returning an -EINVAL to prevent them from being loaded. So with this change, I can
1) 'modprobe tcrypt' and have all fips approved algs self-tested, and *only* fips approved algs tested
2) 'modprobe md4' for example, and in fips mode, have the module load rejected as invalid
Patch 1/2 adds the basic infra
Patch 2/2 marks the allowed algs
