While the hardware consider them to be blockciphers, the reference implementation defines them as streamciphers.
Do the right thing and set the blocksize to 1. This was found by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS. This fixes the following issues: skcipher: blocksize for ofb-aes-ppc4xx (16) doesn't match generic impl (1) skcipher: blocksize for cfb-aes-ppc4xx (16) doesn't match generic impl (1) Cc: Eric Biggers <[email protected]> Cc: [email protected] Fixes: f2a13e7cba9e ("crypto: crypto4xx - enable AES RFC3686, ECB, CFB and OFB offloads") Signed-off-by: Christian Lamparter <[email protected]> --- drivers/crypto/amcc/crypto4xx_core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/crypto/amcc/crypto4xx_core.c b/drivers/crypto/amcc/crypto4xx_core.c index 0322ae8ac466..5f2709cffc5b 100644 --- a/drivers/crypto/amcc/crypto4xx_core.c +++ b/drivers/crypto/amcc/crypto4xx_core.c @@ -1231,7 +1231,7 @@ static struct crypto4xx_alg_common crypto4xx_alg[] = { .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, .cra_flags = CRYPTO_ALG_ASYNC | CRYPTO_ALG_KERN_DRIVER_ONLY, - .cra_blocksize = AES_BLOCK_SIZE, + .cra_blocksize = 1, .cra_ctxsize = sizeof(struct crypto4xx_ctx), .cra_module = THIS_MODULE, }, @@ -1311,7 +1311,7 @@ static struct crypto4xx_alg_common crypto4xx_alg[] = { .cra_priority = CRYPTO4XX_CRYPTO_PRIORITY, .cra_flags = CRYPTO_ALG_ASYNC | CRYPTO_ALG_KERN_DRIVER_ONLY, - .cra_blocksize = AES_BLOCK_SIZE, + .cra_blocksize = 1, .cra_ctxsize = sizeof(struct crypto4xx_ctx), .cra_module = THIS_MODULE, }, -- 2.20.1
