crypto: testmgr - add diff-splits of src/dst into default cipher config

2023-02-10T09:20:19+00:00

This type of request is often happened in AF_ALG cases.
So add this vector in default cipher config array.

crypto: testmgr - disallow certain DRBG hash functions in FIPS mode

2023-01-27T10:58:09+00:00

According to FIPS 140-3 IG, section D.R "Hash Functions Acceptable for
Use in the SP 800-90A DRBGs", modules certified after May 16th, 2023
must not support the use of: SHA-224, SHA-384, SHA512-224, SHA512-256,
SHA3-224, SHA3-384. Disallow HMAC and HASH DRBGs using SHA-384 in FIPS
mode.

crypto: testmgr - allow ecdsa-nist-p256 and -p384 in FIPS mode

2023-01-06T09:15:47+00:00

The kernel provides implementations of the NIST ECDSA signature
verification primitives. For key sizes of 256 and 384 bits respectively
they are approved and can be enabled in FIPS mode. Do so.

crypto: testmgr - disallow plain ghash in FIPS mode

2023-01-06T09:15:47+00:00

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.

2022-11-25T18:01:55+00:00

READ/WRITE proved to be actively confusing - the meanings are
"data destination, as used with read(2)" and "data source, as
used with write(2)", but people keep interpreting those as
"we read data from it" and "we write data to it", i.e. exactly
the wrong way.

Call them ITER_DEST and ITER_SOURCE - at least that is harder
to misinterpret...
