From 331351f89c36bf7d03561a28b6f64fa10a9f6f3a Mon Sep 17 00:00:00 2001 From: Horia Geantă Date: Wed, 12 Sep 2018 16:20:48 +0300 Subject: crypto: tcrypt - fix ghash-generic speed test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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: # 4.6+ Fixes: 0660511c0bee ("crypto: tcrypt - Use ahash") Tested-by: Franck Lenormand Signed-off-by: Horia Geantă Acked-by: Ard Biesheuvel Signed-off-by: Herbert Xu --- crypto/tcrypt.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'crypto/tcrypt.c') diff --git a/crypto/tcrypt.c b/crypto/tcrypt.c index bdde95e8d369..6e0a054bb61d 100644 --- a/crypto/tcrypt.c +++ b/crypto/tcrypt.c @@ -1103,6 +1103,9 @@ static void test_ahash_speed_common(const char *algo, unsigned int secs, 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); -- cgit v1.2.3-59-g8ed1b
