crypto: null - Remove VLA usage of skcipher 2018-09-28T04:46:08+00:00 Kees Cook keescook@chromium.org 2018-09-19T02:10:51+00:00 8d605398425843c7ce3c0e9a0434d832d3bd54cc 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 2018-07-08T16:30:24+00:00 Eric Biggers ebiggers@google.com 2018-06-30T22:16:11+00:00 e50944e219f908968a6e01fbd0e8811a33bd5f04 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.
