Hi Herbert,

do I understand the crypto code correctly, that although crypto/testmgr.c in
alg_test() returns -EINVAL for non-fips allowed algorithms (that means
failing crypto API test) the API in crypto_alg_lookup() returns -ELIBBAD for
failed test?

Why ELIBBAD and not ENOENT like for missing ciphers? To distinguish between
missing cipher and disabled one due fips?

Kind regards,
Petr
