As before, when the ZIP device is too busy to creat a request, it will return '-EBUSY'. But the crypto process think the '-EBUSY' means a successful request and wait for its completion. So replace '-EBUSY' with '-EAGAIN' to show crypto this request is failed. Fixes: 62c455ca("crypto: hisilicon - add HiSilicon ZIP...") Signed-off-by:

The digital certificate format based on SM2 crypto algorithm as specified in GM/T 0015-2012. It was published by State Encryption Management Bureau, China. The method of generating Other User Information is defined as ZA=H256(ENTLA || IDA || a || b || xG || yG || xA || yA), it also specified in https://tools.ietf.org/html/draft-shen-sm2-ecdsa-02. The x509 certificate supports SM2-with-SM3 type certificate verification. Because certificate verification requires ZA in addition to tbs data, ZA also depends on elliptic curve parameters and public key data, so you need to access tbs in sig and calculate ZA. Finally calculate the digest of the signature and complete the verification work. The calculation process of ZA is declared in specifications GM/T 0009-2012 and GM/T 0003.2-2012. Signed-off-by:

This patch adds the OID object identifier defined by OSCCA. The x509 certificate supports SM2-with-SM3 type certificate parsing. It uses the standard elliptic curve public key, and the sm2 algorithm signs the hash generated by sm3. Signed-off-by:

When the 'key' allocation fails, the 'req' will not be released, which will cause memory leakage on this path. This patch adds a 'free_req' tag used to solve this problem, and two new err values are added to reflect the real reason of the error. Signed-off-by:

Some asymmetric algorithms will get different ciphertext after each encryption, such as SM2, and let testmgr support the testing of such algorithms. In struct akcipher_testvec, set c and c_size to be empty, skip the comparison of the ciphertext, and compare the decrypted plaintext with m to achieve the test purpose. Signed-off-by:

Extend the user-space RNG interface: 1. Add entropy input via ALG_SET_DRBG_ENTROPY setsockopt option; 2. Add additional data input via sendmsg syscall. This allows DRBG to be tested with test vectors, for example for the purpose of CAVP testing, which otherwise isn't possible. To prevent erroneous use of entropy input, it is hidden under CRYPTO_USER_API_RNG_CAVP config option and requires CAP_SYS_ADMIN to succeed. Signed-off-by:
