Subject[PATCH] crypto: testmgr - disallow certain DRBG hash functions in FIPS mode
Date
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.

Some details:

The following DRBG algos are defined in testmgr.c as of now:

drbg_{no,}pr_ctr_aes128
drbg_{no,}pr_ctr_aes192
drbg_{no,}pr_ctr_aes256

drbg_{no,}pr_hmac_sha1
drbg_{no,}pr_hmac_sha256
drbg_{no,}pr_hmac_sha384 (disallow)
drbg_{no,}pr_hmac_sha512

drbg_{no,}pr_sha1
drbg_{no,}pr_sha256
drbg_{no,}pr_sha384 (disallow)
drbg_{no,}pr_sha512

Marked DRBGs should be disallowed in FIPS mode according to
the requirements above.
