* chacha20poly1305: permit unaligned strides on certain platformsJason A. Donenfeld2019-02-031-18/+14
| | | | | | | The map allocations required to fix this are mostly slower than unaligned paths. Reported-by: Louis Sautier <sbraz@gentoo.org>

* chacha20: do not define unused asm functionJason A. Donenfeld2018-12-071-4/+2
| | | | | | This causes RAP to be unhappy, and we're not using it anyway. Reported-by: Ivan J. <parazyd@dyne.org>

|
* chacha20,poly1305: fix up for win64Samuel Neves2018-11-152-27/+29
| | | | | | | These don't help us, but it is important to keep this working for when it's re-added to cryptogams. Signed-off-by: Samuel Neves <sneves@dei.uc.pt>
* perlasm: avoid rep retJason A. Donenfeld2018-11-151-1/+1
| | | | | | | | The original hardcodes returns as .byte 0xf3,0xc3, aka "rep ret". We replace this by "ret". "rep ret" was meant to help with AMD K8 chips, cf. http://repzret.org/p/repzret. It makes no sense to continue to use this kludge for code that won't even run on ancient AMD chips.

* chacha20: fixup win64 stack offsetsSamuel Neves2018-11-141-129/+129
| | | | | | We don't need to do this for kernel purposes, but it's polite to leave things unbroken. Signed-off-by: Samuel Neves <sneves@dei.uc.pt>
* chacha20: simplify stack unwinding on ChaCha20_ctr32Samuel Neves2018-11-141-10/+8
| | | | | | objtool did not quite understand the stack arithmetic employed here. Signed-off-by: Samuel Neves <sneves@dei.uc.pt>
* chacha20: use DRAP idiomSamuel Neves2018-11-141-236/+235
| | | | | | This effectively means swapping the usage of %r9 and %r10 globally. Signed-off-by: Samuel Neves <sneves@dei.uc.pt>

* chacha20,poly1305: use CONFIG_KERNEL_MODE_NEON in .pl on armJason A. Donenfeld2018-11-144-8/+11
| | | | | | While Andy is right to desire a separation between compiler defines and project defines, there are simply too many odd kernel configurations and we require testing for CONFIG_KERNEL_MODE_NEON.
* chacha20,poly1305: switch to perlasm originals on mips and armJason A. Donenfeld2018-11-1411-6103/+5563
| | | | | We also separate out Eric Biggers' Cortex A7 implementation into its own file.
* global: various formatting tweeksJason A. Donenfeld2018-11-132-2/+1

* curve25519-x86_64: this was relicensed to BSD-3-Clause upstreamJason A. Donenfeld2018-10-271-1/+1

* poly1305-donna64: mark large constants as ULLJason A. Donenfeld2018-10-271-24/+24
|
* crypto: clean up remaining .h->.cJason A. Donenfeld2018-10-078-10/+10
|
* crypto: use BIT(i) & bitmap instead of (bitmap >> i) & 1Jason A. Donenfeld2018-10-071-2/+2
| | | | | | | | | | | Pros: clearer if you're not familiar with the shift idiom, uses kernel macro. Cons: doesn't work any more if the lvalue ever ceases to be a bool. Neutral: generates the same machine code. Suggested-by: Sultan Alsawaf <sultanxda@gmail.com>
* crypto: disable broken implementations in selftestsJason A. Donenfeld2018-10-071-9/+8

* crypto: test all SIMD combinationsJason A. Donenfeld2018-10-0620-40/+82
|
* global: rename include'd C files to be .cJason A. Donenfeld2018-10-0619-28/+28
| | | | | | | | | This is done by 259 other files in the kernel tree: linux $ rg '#include.*\.c' -l | wc -l 259 Suggested-by: Sultan Alsawaf <sultanxda@gmail.com>

|
* chacha20: split chacha20_ctx into unionJason A. Donenfeld2018-10-024-24/+24
| | | | This avoids casts and makes counter increments obvious.
