crypto: geode-aes - switch to skcipher for cbc(aes) fallback

2019-12-13T07:49:28Z

commit 504582e8e40b90b8f8c58783e2d1e4f6a2b71a3a upstream. Commit 79c65d179a40e145 ("crypto: cbc - Convert to skcipher") updated the generic CBC template wrapper from a blkcipher to a skcipher algo, to get away from the deprecated blkcipher interface. However, as a side effect, drivers that instantiate CBC transforms using the blkcipher as a fallback no longer work, since skciphers can wrap blkciphers but not the other way around. This broke the geode-aes driver. So let's fix it by moving to the sync skcipher interface when allocating the fallback. At the same time, align with the generic API for ECB and CBC by rejecting inputs that are not a multiple of the AES block size.

This is actually defined in include/crypto/aes.h , no need to have a a different symbol for the same thing twice.

[CRYPTO] geode: do not copy the IV too often

2008-01-10T21:16:26Z

There is no reason to keep the IV in the private structre. Instead keep just a pointer to make the patch smaller :) This also remove a few memcpy()s Signed-off-by: Sebastian Siewior Signed-off-by: Herbert Xu

[CRYPTO] geode: Add fallback for unsupported modes

2008-01-10T21:16:11Z

The Geode AES crypto engine supports only 128 bit long key. This patch adds fallback for other key sizes which are required by the AES standard. Signed-off-by: Sebastian Siewior Acked-by: Jordan Crouse Signed-off-by: Herbert Xu

[CRYPTO] geode: Fix in-place operations and set key

2007-05-24T11:23:24Z

Allow in-place crypto operations. Also remove the coherent user flag (we use it automagically now), and by default use the user written key rather then the HW hidden key - this makes crypto just work without any special considerations, and thats OK, since its our only usage model.
