The base is v14 of the vector patchset but the first patches up to doing
the Zbc-based GCM GHash can also run without those. Of course the vector-
crypto extensions are also not ratified yet, hence the marking as RFC.
As v13 of the vector patchset dropped the patches for in-kernel usage of
vector instructions, I picked the ones from v12 over into this series
for now.
My basic goal was to not re-invent cryptographic code, so the heavy
lifting is done by those perl-asm scripts used in openssl and the perl
code used here-in stems from code that is targetted at openssl [0] and is
unmodified from there to limit needed review effort.
With a matching qemu (there are patches for vector-crypto flying around)
the in-kernel crypto-selftests (also the extended ones) are very happy
so far.
Things to do:
- use correct Co-developed-attribution for the code coming from
openssl
- follow openSSL changes along until they get eventually merged
changes in v3:
- rebase on top of 6.3-rc2
- rebase on top of vector-v14 patchset
- add the missing Co-developed-by mentions to showcase
the people that did the actual openSSL crypto code
changes in v2:
- rebased on 6.2 + zbb series, so don't include already
applied changes anymore
- refresh code picked from openssl as that side matures
- more algorithms (SHA512, AES, SM3, SM4)
[0] both still open
