2018-11-14chacha20: simplify stack unwinding on ChaCha20_ctr32Samuel Neves
objtool did not quite understand the stack arithmetic employed here. Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-11-14chacha20: use DRAP idiomSamuel Neves

2018-11-14chacha20,poly1305: use CONFIG_KERNEL_MODE_NEON in .pl on armJason A. Donenfeld
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-11-14chacha20,poly1305: switch to perlasm originals on mips and armJason A. Donenfeld

2018-10-07crypto: use BIT(i) & bitmap instead of (bitmap >> i) & 1Jason A. Donenfeld
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> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-10-02chacha20: split chacha20_ctx into unionJason A. Donenfeld

2018-10-02crypto: WARN_ON in module_init if selftest failsJason A. Donenfeld
If it's a built-in and initcall fails, it won't be fatal. So we should at least be loud. Suggested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-02poly1305-mips64: use compiler-defined macros in assemblyJason A. Donenfeld
Andy and I agreed it's more correct to use the compiler-defined macros in assembly code, and not the project specific macros. Suggested-by: Andy Polyakov <appro@openssl.org> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-09-25poly1305-arm: swap endianness in base 2^26 conversionJason A. Donenfeld
These are actually 32-bit limbs, so we have to swap them back after the 64-bit arithmetic. Also, change type of boolean for 64-bit. Suggested-by: Andy Polyakov <appro@openssl.org> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-25curve25519-arm: disable on big-endianJason A. Donenfeld
