2019-03-22	crypto: arm64 - convert to use crypto_simd_usable()	Eric Biggers	1	-3/+4
	Replace all calls to may_use_simd() in the arm64 crypto code with crypto_simd_usable(), in order to allow testing the no-SIMD code paths.

2018-07-09	crypto: shash - remove useless setting of type flags	Eric Biggers	1	-1/+0
	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.

2017-08-04	crypto: arm64/sha1-ce - add non-SIMD generic fallback	Ard Biesheuvel	1	-4/+14
	The arm64 kernel will shortly disallow nested kernel mode NEON, so add a fallback to scalar C code that can be invoked in that case. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2017-05-18	crypto: arm64/sha - avoid non-standard inline asm tricks	Ard Biesheuvel	1	-8/+3
	Replace the inline asm which exports struct offsets as ELF symbols with proper const variables exposing the same values. This works around an issue with Clang which does not interpret the "i" (or "I") constraints in the same way as GCC.

2015-05-07	crypto: arm64/sha1-ce - prevent asm code finalization in final() path	Ard Biesheuvel	1	-0/+3
	Ensure that the asm code finalization path is not triggered when invoked via final(), since it already takes care of that itself. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-04-10	crypto: arm64/sha1-ce - move SHA-1 ARMv8 implementation to base layer	Ard Biesheuvel	1	-107/+44
	This removes all the boilerplate from the existing implementation, and replaces it with calls into the base layer. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2014-05-14	arm64/crypto: SHA-1 using ARMv8 Crypto Extensions	Ard Biesheuvel	1	-0/+174
	This patch adds support for the SHA-1 Secure Hash Algorithm for CPUs that have support for the SHA-1 part of the ARM v8 Crypto Extensions. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Herbert Xu <herbert@gondor.apana.org.au>
