Subject: [PATCH 14/15] crypto: crypto4xx - fix blocksize for cfb and ofb
|
||
|
|
||
|
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)
