Herbert, There are some ahash algorithms like x86's sha1-mb and ghash that failed to register because of the newly added check of non-zero statesize from commit 8996eafd. But since there are algorithms that do not implement an import or export, there is no state required for them. Wonder if the check should be modified to something like: diff --git a/crypto/ahash.c b/crypto/ahash.c index 9c1dc8d..f512183 100644 --- a/crypto/ahash.c +++ b/crypto/ahash.c @@ -544,7 +544,10 @@ static int ahash_prepare_alg(struct ahash_alg *alg) struct crypto_alg *base = &alg->halg.base; if (alg->halg.digestsize > PAGE_SIZE / 8 || - alg->halg.statesize > PAGE_SIZE / 8 || + alg->halg.statesize > PAGE_SIZE / 8) + return -EINVAL; + + if ((alg->import || alg->export) && alg->halg.statesize == 0) return -EINVAL; Thanks.
