2018-10-07compat: clang cannot handle __builtin_constant_pJason A. Donenfeld
Or, put differently, we don't want to go chasing down random versions of clang used by XDA users, so we just disable this checking on clang all together. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-07compat: make asm/simd.h conditional on its existenceJason A. Donenfeld

Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-02qemu: support powerpc64leJason A. Donenfeld
This uses ELFv2 ABI, which is the only ppc64 ABI musl supports. Big endian uses ELFv1 ABI, which musl doesn't support. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-02qemu: give up and accept a mips64r2 worldJason A. Donenfeld
We can't do SMP this way, and we also fall back to using the default N32 ABI, which is a bummer. But the mips64r6 toolchain is too much of a hassle to build with Gentoo's crossdev, and at least this works. 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>

2018-10-02global: prefix all functions with wg_Jason A. Donenfeld
I understand why this must be done, though I'm not so happy about having to do it. In some places, it puts us over 80 chars and we have to break lines up in further ugly ways. And in general, I think this makes things harder to read. Yet another thing we must do to please upstream. Maybe this can be replaced in the future by some kind of automatic module namespacing logic in the linker, or even combined with LTO and aggressive symbol stripping.

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>

2018-10-02compat: kernels < 3.17 don't have read_cpuid_partNathan Chancellor
Use read_cpuid_part_number, which was the same thing before upstream commit af040ffc9ba1 ("ARM: make it easier to check the CPU part number correctly"). Signed-off-by: Nathan Chancellor <natechancellor@gmail.com> 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>
