4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Horia Geantă <[email protected]> commit 331351f89c36bf7d03561a28b6f64fa10a9f6f3a upstream. ghash is a keyed hash algorithm, thus setkey needs to be called. Otherwise the following error occurs: $ modprobe tcrypt mode=318 sec=1 testing speed of async ghash-generic (ghash-generic) tcrypt: test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): tcrypt: hashing failed ret=-126 Cc: <[email protected]> # 4.6+ Fixes: 0660511c0bee ("crypto: tcrypt - Use ahash") Tested-by: Franck Lenormand <[email protected]> Signed-off-by: Horia Geantă <[email protected]> Acked-by: Ard Biesheuvel <[email protected]> Signed-off-by: Herbert Xu <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- crypto/tcrypt.c | 3 +++ 1 file changed, 3 insertions(+) --- a/crypto/tcrypt.c +++ b/crypto/tcrypt.c @@ -727,6 +727,9 @@ static void test_ahash_speed_common(cons break; } + if (speed[i].klen) + crypto_ahash_setkey(tfm, tvmem[0], speed[i].klen); + pr_info("test%3u " "(%5u byte blocks,%5u bytes per update,%4u updates): ", i, speed[i].blen, speed[i].plen, speed[i].blen / speed[i].plen);
