2023-09-20crypto: sm2 - Fix crash caused by uninitialized contextTianjia Zhang1-1/+5
In sm2_compute_z_digest() function, the newly allocated structure mpi_ec_ctx is used, but forget to initialize it, which will cause a crash when performing subsequent operations. Fixes: e5221fa6a355 ("KEYS: asymmetric: Move sm2 code into x509_public_key") Cc: stable@vger.kernel.org # v6.5 Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-06-23KEYS: asymmetric: Move sm2 code into x509_public_keyHerbert Xu1-36/+70
The sm2 certificate requires a modified digest. Move the code for the hashing from the signature verification path into the code where we generate the digest. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2022-01-28crypto: sm2 - make dependent on sm3 libraryTianjia Zhang1-19/+19
SM3 generic library is stand-alone implementation, it is necessary for the calculation of sm2 z digest to depends on SM3 library instead of sm3-generic. Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2021-06-11crypto: sm2 - fix a memory leak in sm2Hongbo Li1-14/+10
SM2 module alloc ec->Q in sm2_set_pub_key(), when doing alg test in test_akcipher_one(), it will set public key for every test vector, and don't free ec->Q. This will cause a memory leak. This patch alloc ec->Q in sm2_ec_ctx_init().

2020-10-30crypto: sm2 - remove unnecessary reset operationsTianjia Zhang1-46/+29
This is an algorithm optimization. The reset operation when setting the public key is repeated and redundant, so remove it. At the same time, `sm2_ecc_os2ec()` is optimized to make the function more simpler and more in line with the Linux code style.
