This series converts fs/smb/server/ to access SHA-512, HMAC-SHA256, and
HMAC-MD5 using the library APIs instead of crypto_shash.

This simplifies the code significantly.  It also slightly improves
performance, as it eliminates unnecessary overhead.  I haven't done
server-specific benchmarks, but you can get an idea of what to expect by
looking at the numbers I gave for the similar client-side series:
https://lore.kernel.org/linux-cifs/20251014034230.GC2763@sol/

No change in behavior intended.  All the crypto computations should be
the same as before.  I haven't tested this series (I did test the
similar client-side series), but everything should still work.

Eric Biggers (3):
  ksmbd: Use SHA-512 library for SMB3.1.1 preauth hash
  ksmbd: Use HMAC-SHA256 library for message signing and key generation
  ksmbd: Use HMAC-MD5 library for NTLMv2
