2016-07-19T07:42:42Z

This patch adds a missing comment for the base parameter in struct skcipher_alg. Reported-by: kbuild test robot Signed-off-by: Herbert Xu

crypto: skcipher - Remove top-level givcipher interface

2016-07-18T09:35:46Z

This patch removes the old crypto_grab_skcipher helper and replaces it with crypto_grab_skcipher2. As this is the final entry point into givcipher this patch also removes all traces of the top-level givcipher interface, including all implicit IV generators such as chainiv. The bottom-level givcipher interface remains until the drivers using it are converted. Signed-off-by: Herbert Xu

crypto: skcipher - Add low-level skcipher interface

2016-07-18T09:35:36Z

This patch allows skcipher algorithms and instances to be created and registered with the crypto API. They are accessible through the top-level skcipher interface, along with ablkcipher/blkcipher algorithms and instances. This patch also introduces a new parameter called chunk size which is meant for ciphers such as CTR and CTS which ostensibly can handle arbitrary lengths, but still behave like block ciphers in that you can only process a partial block at the very end. For these ciphers the block size will continue to be set to 1 as it is now while the chunk size will be set to the underlying block size. Signed-off-by: Herbert Xu

crypto: skcipher - Fix driver name helper

2016-02-06T07:33:13Z

The helper crypto_skcipher_driver_name was returning the alg name and not the driver name. Signed-off-by: Herbert Xu

crypto: skcipher - Add helper to retrieve driver name

2016-01-27T12:35:22Z

This patch adds the helper crypto_skcipher_driver_name which returns the driver name of the alg object for a given tfm. This is needed by ecryptfs. Signed-off-by: Herbert Xu

crypto: skcipher - Add helper to zero stack request

2016-01-25T14:42:12Z

As the size of an skcipher_request is variable, it's awkward to zero it explicitly. This patch adds a helper to do that which should be used when it is created on the stack. Signed-off-by: Herbert Xu

crypto: skcipher - Add default key size helper

2016-01-25T14:42:11Z

While converting ecryptfs over to skcipher I found that it needs to pick a default key size if one isn't given. Rather than having it poke into the guts of the algorithm to get max_keysize, let's provide a helper that is meant to give a sane default (just in case we ever get an algorithm that has no maximum key size).

crypto: skcipher - Add crypto_skcipher_has_setkey

2016-01-18T10:16:12Z

This patch adds a way for skcipher users to determine whether a key is required by a transform. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu

crypto: skcipher - Add top-level skcipher interface

2015-08-21T14:21:19Z

This patch introduces the crypto skcipher interface which aims to replace both blkcipher and ablkcipher. It's very similar to the existing ablkcipher interface. The main difference is the removal of the givcrypt interface. In order to make the transition easier for blkcipher users, there is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place a request on the stack for synchronous transforms.
