[PATCH v2 0/4] virtio-crypto: support ECDSA algorithm

[Lei He]

From: lei he <helei.sig11@xxxxxxxxxxxxx>

This patch supports the ECDSA algorithm for virtio-crypto.

V1 -> V2:
- explicitly specified an appropriate base commit.
- fixed the link error reported by kernel test robot <lkp@xxxxxxxx>.
- removed irrelevant commits.

V1:
- fixed the problem that the max_signature_size of ECDSA is
incorrectly calculated.
- make pkcs8_private_key_parser can identify ECDSA private keys.
- implement ECDSA algorithm for virtio-crypto device


lei he (4):
  crypto: fix the calculation of max_size for ECDSA
  crypto: pkcs8 parser support ECDSA private keys
  crypto: remove unused field in pkcs8_parse_context
  virtio-crypto: support ECDSA algorithm
