The name sm3-256 is defined in hash_algo_name in hash_info, but the algorithm name implemented in sm3_generic.c is sm3, which will cause the sm3-256 algorithm to be not found in some application scenarios of the hash algorithm, and an ENOENT error will occur. For example, IMA, keys, and other subsystems that reference hash_algo_name all use the hash algorithm of sm3. According to https://tools.ietf.org/id/draft-oscca-cfrg-sm3-01.html, SM3 always produces a 256-bit hash value and there are no plans for other length development, so there is no ambiguity in the name of sm3. Signed-off-by: Tianjia Zhang <redacted> Cc: Jarkko Sakkinen <redacted>The previous version of this patch set is queued in the next- integrity-testing branch. That version of this patch didn't change TPM_ALG_SM3_256. Unless the TPM standard was modified, the TPM spec refers to it as TPM_ALG_SM3_256. Has that changed? Mimi
The definition in the TPM specification is still TPM_ALG_SM3_256, please ignore the modification to the TPM definition in this patch. Thanks, Tianjia
