2019-12-11crypto: x86 - Regularize glue function prototypesKees Cook1-12/+18
The crypto glue performed function prototype casting via macros to make indirect calls to assembly routines. Instead of performing casts at the call sites (which trips Control Flow Integrity prototype checking), switch each prototype to a common standard set of arguments which allows the removal of the existing macros. In order to keep pointer math unchanged, internal casting between u128 pointers and u8 pointers is added.

2018-03-03crypto: x86/serpent-sse2 - convert to skcipher interfaceEric Biggers1-151/+70
Convert the SSE2 implementation of Serpent from the (deprecated) ablkcipher and blkcipher interfaces over to the skcipher interface.

2018-03-03crypto: x86/serpent-sse2 - remove XTS algorithmEric Biggers1-172/+0
The XTS template now wraps an ECB mode algorithm rather than the block cipher directly. Therefore it is now redundant for crypto modules to wrap their ECB code with generic XTS code themselves via xts_crypt(). Remove the xts-serpent-sse2 algorithm which did this. Users who request xts(serpent) and previously would have gotten xts-serpent-sse2 will now get xts(ecb-serpent-sse2) instead, which is just as fast.

2017-04-05crypto: gf128mul - switch gf128mul_x_ble to le128Ondrej Mosnáček1-2/+2
Currently, gf128mul_x_ble works with pointers to be128, even though it actually interprets the words as little-endian. Consequently, it uses cpu_to_le64/le64_to_cpu on fields of type __be64, which is incorrect. This patch fixes that by changing the function to accept pointers to le128 and updating all users accordingly.

2016-02-17crypto: xts - consolidate sanity check for keysStephan Mueller1-8/+3
The patch centralizes the XTS key check logic into the service function xts_check_key which is invoked from the different XTS implementations. With this, the XTS implementations in ARM, ARM64, PPC and S390 have now a sanity check for the XTS keys similar to the other arches. In addition, this service function received a check to ensure that the key != the tweak key which is mandated by FIPS 140-2 IG A.9. As the check is not present in the standards defining XTS, it is only enforced in FIPS mode of the kernel.
