Patches 1-4 remove the MD5 implementations for mips, powerpc, and sparc.
These were the only architecture-optimized MD5 implementations and are
not worth keeping around.
Patches 5-7 introduce a library API for MD5 and HMAC-MD5 and reimplement
the crypto_shash "md5" and "hmac(md5)" on top of it.
The library API will also be usable directly by various in-kernel users
that are stuck with MD5 due to having to implement legacy protocols.
This should again look quite boring and familiar, as it mirrors the
SHA-1 and SHA-2 changes closely. The MD5 changes are quite a bit
simpler, though, since we'll only be supporting the generic C MD5 code.
Of course there's also only one variant of MD5, unlike e.g. SHA-2.
Eric Biggers (7):
mips: cavium-octeon: Remove Octeon optimized MD5 code
mips: cavium-octeon: Move octeon-crypto.c into parent dir
crypto: powerpc/md5 - Remove PowerPC optimized MD5 code
crypto: sparc/md5 - Remove SPARC64 optimized MD5 code
lib/crypto: md5: Add MD5 and HMAC-MD5 library functions
crypto: md5 - Wrap library and add HMAC support
lib/crypto: tests: Add KUnit tests for MD5 and HMAC-MD5
