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>

2018-10-02crypto: 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>

Also we make selftest errors of type err, so that they're obvious in dmesg. 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

2018-09-23curve25519-fiat32: work around m68k compiler stack frame bugJason A. Donenfeld
The m68k compiler generates a 1032 byte stack frame. Moving these variables inside the loop fixes that. It also means we're not explicitly memzeroing it any more either, but hopefully that memory is reused anyway by the multiplications. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-23chacha20-arm: use new scalar implementationJason A. Donenfeld
It turns out this is faster than NEON on some chips, so it's nice to have. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
