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 crypto/Kconfig | 1 + crypto/Makefile | 2 + crypto/akcipher.c | 10 + crypto/asymmetric_keys/pkcs8.asn1 | 2 +- crypto/asymmetric_keys/pkcs8_parser.c | 46 +++- crypto/ecdsa.c | 3 +- crypto/ecdsa_helper.c | 45 +++ drivers/crypto/virtio/Kconfig | 1 + .../virtio/virtio_crypto_akcipher_algs.c | 259 ++++++++++++++++-- include/crypto/internal/ecdsa.h | 15 + include/linux/asn1_encoder.h | 2 + lib/asn1_encoder.c | 3 +- 12 files changed, 361 insertions(+), 28 deletions(-) create mode 100644 crypto/ecdsa_helper.c create mode 100644 include/crypto/internal/ecdsa.h base-commit: 018ab4fabddd94f1c96f3b59e180691b9e88d5d8 -- 2.20.1
