This was originally part of my vector crypto series, but was part
of a separate openssl merge request implementing GCM ghash as using
non-vector extensions.
As that pull-request
https://github.com/openssl/openssl/pull/20078
got merged recently into openssl, we could also check if this could
go into the kernel as well and provide a base for further accelerated
cryptographic support.
changes in v6:
- rebase on top of riscv/for-next
- rebase on top of Samuel Ortiz Arch-random series
https://lore.kernel.org/r/20230709115549.2666557-1-sameo@rivosinc.com
as it has the nicer Zbc + Zbkb integration for extensions and hwprobe
- update perl code with better licensing text (Eric)
This was also merged into the original openSSL sources
- add SPDX license identifier (Eric)
- drop unneeded fallback element in the private struct (Herbert)
Changes in v5:
- rebased on top of 6.4-based riscv/next
- code from openssl is now dual-licensed under Apache + BSD
see https://github.com/openssl/openssl/pull/20649
- separate init functions instead of creating them with macros (Nathan)
Changes in v4:
- rebase on top of riscv/for-next
- split out the scalar crypto implementation from the vector series
- refresh code from openSSL to match exactly
- Remove RFC label, as Zbc and Zbkb are ratified and
the cryptographic code was merged into openSSL
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)
