crypto: af_alg - cast ki_complete ternary op to int
when libkcapi test is executed using HW accelerator, cipher operation return -74.Since af_alg_async_cb->ki_complete treat err as unsigned int, libkcapi receive 429467222 even though it expect -ve value. Hence its required to cast resultlen to int so that proper error is returned to libkcapi. AEAD one shot non-aligned test 2(libkcapi test) ./../bin/kcapi -x 10 -c "gcm(aes)" -i 7815d4b06ae50c9c56e87bd7 -k ea38ac0c9b9998c80e28fb496a2b88d9 -a "853f98a750098bec1aa7497e979e78098155c877879556bb51ddeb6374cbaefc" -t "c4ce58985b7203094be1d134c1b8ab0b" -q "b03692f86d1b8b39baf2abb255197c98" Fixes: d887c52d6ae4 ("crypto: algif_aead - overhaul memory management") Cc: <stable@vger.kernel.org> Signed-off-by: Ayush Sawal <ayush.sawal@chelsio.com> Signed-off-by: Atul Gupta <atul.gupta@chelsio.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Ayush Sawal <ayush.sawal@chelsio.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
