[RFC PATCH 0/2] AES in CBC/CTR/XTS modes using ARMv8 Crypto Extensions

Hello all, This is a first attempt at getting something implemented that uses the ARMv8 crypto extensions for performing AES encryption in CBC, CTR and XTS modes. The first patch moves the ablk helper code out of arch/x86. This code is used to automagically instantiate async blkciphers based on t

[RFC PATCH 1/2] crypto: move ablk_helper out of arch/x86

Move the ablk_helper code out of arch/x86 so it can be reused by other architectures. The only x86 specific dependency was a call to irq_fpu_usable(), this has been factored out and moved to crypto/ablk_helper_x86.c Signed-off-by: Ard Biesheuvel --- arch/x86/crypto/Makefile |

Crypto Fixes for 3.12

Hi Linus: This push fixes a 7+ year race condition in the crypto API that causes sporadic crashes when multiple threads load the same algorithm. It also fixes the crct10dif algorithm again to prevent boot failures on systems where the initramfs tool ignores module softdeps. Please pull from git
