Changes since v7: - Do not check callback validity in akcipher requests, instead define default callbacks on register, suggested by Herbert Xu. - Sanity checks in crypto_akcipher_maxsize are removed (not needed). - Sanity checks for `dst' and `dst_len' are removed from verify op (not needed in akcipher API and should be checked by a driver). - Patch "KEYS: report to keyctl only actually supported key ops" is removed, as it would affect user-space API. Changes since (v5-v6): - set_params API is removed in favor of appending parameters into a key stream, as requested by Herbert Xu. - verify op signature de-kmemdup'ed (as requested by David Howells) in separate patch (as requested by Herbert Xu). - Add forgotten ASN.1 parser files to EC-RDSA patch. - Tested on x86_64. Changes since v5: - Comparison of hash algo by enum id instead of text name, as suggested by Thiago Jung Bauermann and Mimi Zohar. Changes since RFC (v1-v4): - akcipher set_max_size, encrypt, decrypt, sign, verify callbacks may be undefined by the drivers, so their crypto_akcipher_* frontends check for their presence before passing the call. - supported_ops flags are set for keyctl, based on the presence of implemented akcipher callbacks. - Transition to verify2 API is abandoned because raw RSA does not need sign/verify ops at all, and we can switch to the new verify in one step. For this RSA backends have sign/verify ops removed as they should only be used (and actually used only) via PKCS1 driver. - Verify callback requires digest as the input parameter in src SGL, as suggested by Herbert Xu, (instead of a separate parameter, as it was in verify2). - For verify op signature is moved into kmalloc'd memory as suggested by Herbert Xu. - set_params API should be called before set_{pub,priv}_key, thus set_*_key knows everything it needs to set they key properly. Also, set_params made optional for back compatibility with RSA drivers. - Public-key cryptography section is created in Kconfig. - ecc.c is made into separate module object, to be used together by ECDH and EC-RDSA. - EC-RDSA parameters and public key are parsed using asn1_ber_decoder as suggested by Stephan Mueller and David Howells. - Test vectors are added and tests are passing. - Curves/parameters definitions are split from ecrdsa.c into ecrdsa_defs.h. - Integration with IMA in asymmetric_verify(). Userspace ima-evm-utils already have a patch in the queue to support this. Tested on x86_64.
