The HKDF self-tests depend on the HMAC algorithms being registered.
HMAC is now registered at module_init, which put it at the same level as
HKDF. Move HKDF to late_initcall so that it runs afterwards.
Fixes: ef93f1562803 ("Revert "crypto: run initcalls for generic implementations earlier"")

crypto: testmgr - replace CRYPTO_MANAGER_DISABLE_TESTS with CRYPTO_SELFTESTS2025-05-12T05:33:14+00:00Eric Biggersebiggers@google.com2025-05-05T20:33:41+00:00urn:sha1:40b9969796bfa49ed1b0f7ddc254f48cb2ac6d2c
The negative-sense of CRYPTO_MANAGER_DISABLE_TESTS is a longstanding
mistake that regularly causes confusion. Especially bad is that you can
have CRYPTO=n && CRYPTO_MANAGER_DISABLE_TESTS=n, which is ambiguous.
Replace CRYPTO_MANAGER_DISABLE_TESTS with CRYPTO_SELFTESTS which has the
expected behavior.
The tests continue to be disabled by default.

crypto,fs: Separate out hkdf_extract() and hkdf_expand()2025-03-20T23:53:53+00:00Hannes Reineckehare@kernel.org2025-02-24T12:38:09+00:00urn:sha1:3241cd0c6c17919b5b984c6b770ced3d797ddc4c
Separate out the HKDF functions into a separate module to
to make them available to other callers.
And add a testsuite to the module with test vectors
from RFC 5869 (and additional vectors for SHA384 and SHA512)
to ensure the integrity of the algorithm.
