Hi Gilad, 2017-01-24 15:38 GMT+01:00 Gilad Ben-Yossef <gilad@xxxxxxxxxxxxx>: > - v->tfm = crypto_alloc_shash(v->alg_name, 0, 0); > + v->tfm = crypto_alloc_ahash(v->alg_name, 0, CRYPTO_ALG_ASYNC); I believe you should pass zero as the mask here. When flags == 0 and mask == CRYPTO_ALG_ASYNC, you are basically saying "I want only algs that have flags & CRYPTO_ALG_ASYNC == 0", which means you should only get ahash tfms that are always synchronous (see [1]). However, since you set a non-NULL callback in verity_hash_init, I don't think this was your intention. By setting the mask to zero, you should be able to get also an actual async tfm.
