crypto: ahash - Fix EINPROGRESS notification callback

2017-04-21T07:31:23Z

commit ef0579b64e93188710d48667cb5e014926af9f1b upstream. The ahash API modifies the request's callback function in order to clean up after itself in some corner cases (unaligned final and missing finup). When the request is complete ahash will restore the original callback and everything is fine. However, when the request gets an EBUSY on a full queue, an EINPROGRESS callback is made while the request is still ongoing. In this case the ahash API will incorrectly call its own callback. This patch fixes the problem by creating a temporary request object on the stack which is used to relay EINPROGRESS back to the original completion function. This patch also adds code to preserve the original flags value. Fixes: ab6bf4e5e5e4 ("crypto: hash - Fix the pointer voodoo in...")

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: aead - Remove blkcipher null for IV generators

2016-07-18T09:35:43Z

The blkcipher null object is no longer used and can now be removed. Signed-off-by: Herbert Xu

crypto: aead - Add skcipher null for IV generators

2016-07-18T09:35:42Z

This patch adds an skcipher null object alongside the existing null blkcipher so that IV generators using it can switch over to skcipher. Signed-off-by: Herbert Xu

crypto: aead - Add chunk size

2016-07-18T09:35:38Z

This patch adds a chunk size parameter to aead algorithms, just like the chunk size for skcipher algorithms. However, unlike skcipher we do not currently export this to AEAD users. It is only meant to be used by AEAD implementors for now. 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: rsa - Store rest of the private key components

2016-07-05T15:05:26Z

When parsing a private key, store all non-optional fields. These are required for enabling CRT mode for decrypt and verify Signed-off-by: Salvatore Benedetto Signed-off-by: Herbert Xu

crypto: kpp - Key-agreement Protocol Primitives API (KPP)

2016-06-23T10:29:56Z

Add key-agreement protocol primitives (kpp) API which allows to implement primitives required by protocols such as DH and ECDH. The API is composed mainly by the following functions * set_secret() - It allows the user to set his secret, also referred to as his private key, along with the parameters known to both parties involved in the key-agreement session. * generate_public_key() - It generates the public key to be sent to the other counterpart involved in the key-agreement session. The function has to be called after set_params() and set_secret() * generate_secret() - It generates the shared secret for the session Other functions such as init() and exit() are provided for allowing cryptographic hardware to be inizialized properly before use Signed-off-by: Salvatore Benedetto Signed-off-by: Herbert Xu

crypto: sha1-mb - async implementation for sha1-mb

2016-06-23T10:29:55Z

Herbert wants the sha1-mb algorithm to have an async implementation: https://lkml.org/lkml/2016/4/5/286. Currently, sha1-mb uses an async interface for the outer algorithm and a sync interface for the inner algorithm. This patch introduces a async interface for even the inner algorithm.

crypto: rsa - return raw integers for the ASN.1 parser

2016-06-15T09:07:54Z

Return the raw key with no other processing so that the caller can copy it or MPI parse it, etc. The scope is to have only one ANS.1 parser for all RSA implementations. Update the RSA software implementation so that it does the MPI conversion on top. Signed-off-by: Tudor Ambarus Signed-off-by: Herbert Xu
