crypto: null - Remove VLA usage of skcipher

2018-09-28T04:46:08Z

In the quest to remove all stack VLA usage from the kernel[1], this replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(), which uses a fixed stack size.

crypto: shash - remove useless setting of type flags

2018-07-08T16:30:24Z

Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this is redundant with the C structure type ('struct shash_alg'), and crypto_register_shash() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the shash algorithms. This patch shouldn't change any actual behavior.

crypto: null - Remove default null blkcipher

2016-07-18T09:35:44Z

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

crypto: null - Add new default null skcipher

2016-07-18T09:35:37Z

Current the default null skcipher is actually a crypto_blkcipher. This patch creates a synchronous crypto_skcipher version of the null cipher which unfortunately has to settle for the name skcipher2. Signed-off-by: Herbert Xu

crypto: null - Add default null skcipher

2015-05-22T03:25:55Z

This patch adds a default null skcipher for users such as gcm to perform copies on SG lists. Signed-off-by: Herbert Xu

crypto: prefix module autoloading with "crypto-"

2014-11-24T14:43:57Z

This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook Signed-off-by: Herbert Xu

crypto: crypto_null - use crypto_[un]register_algs

2012-08-01T09:47:24Z

Combine all crypto_alg to be registered and use new crypto_[un]register_algs functions. This simplifies init/exit code. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu
