crypto: inside-secure - Add support for the Chacha20-Poly1305 AEAD
This patch adds support for the Chacha20-Poly1305 cipher suite.
It adds both the basic rfc7539(chacha20,poly1305) as well as the
rfc7539esp(chacha20,poly1305) variant for IPsec ESP acceleration.
changes since v1:
- rebased on top of DES library changes done on cryptodev/master
- fixed crypto/Kconfig so that generic fallback is compiled as well
changes since v2:
- nothing
changes since v3:
- Fixed a problem where the tcrypt performance test would run fully on the
fallback cipher instead of the HW due to using an AAD length of 8 for
rfc7539esp. While this is not actually legal ESP (which includes SPI and
sequence number in the AAD as well), it is both inconvenient and not
necessary to run these vectors on the fallback cipher.
- Due to above, also realised that for plain (non-ESP) rfc7539, you
probably want to be able to run vectors with less than 8 bytes of AAD
on the HW, and this is actually possible as long as cryptlen is large
enough, so made that possible as well.
