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.

The previous version of this patch set is queued in the next-
integrity-testing branch. ÂThat version of this patch didn't
changeÂTPM_ALG_SM3_256. ÂUnless the TPM standard was modified, the TPM
spec refers to it as TPM_ALG_SM3_256. ÂHas that changed?
