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>
2018-10-02blake2s: rename arch function and use slicker le32 helperJason A. Donenfeld

Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-25crypto: rename DEBUG to SELFTESTJason A. Donenfeld
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
The qhasm was only written for little-endian systems, and we don't want disaster to ensue. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-25chacha20-arm,poly1305-arm: fix big-endian aarch64Jason A. Donenfeld

2018-09-23crypto-arm: rework KERNEL_MODE_NEON handling againJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-23crypto: flatten out makefileJason A. Donenfeld
This brings us more in line with the integration tree's style. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
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>
2018-09-23crypto-arm: rework KERNEL_MODE_NEON handlingJason A. Donenfeld
It might be defined even if the compiler doesn't support it. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-23global: reduce stack frame sizeJason A. Donenfeld
This brings it under 1280 on 64-bit and under 1024 on 32-bit systems. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-23chacha20: add chunked selftest and test sliding alignments and hchacha20Jason A. Donenfeld
This ensures we're properly updating state[12] and that we're handling all unaligned acceses (in the jump tables for MIPS). Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-22chacha20-mips32r2: reduce jumptable entry size and stack usageRené van Dorst

2018-09-21chacha20-mips32r2: use simpler calling conventionJason A. Donenfeld
Since we now set up the block in the generic code, we can rely on that to use fewer variables and reduce stack pressure within the MIPS code. This in turn means we have more registers and more uniformity, so we're able to rewrite quite a bit. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-21chacha20-arm: go with Ard's version to optimize for Cortex-A7Jason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-21chacha20-mips32r2: remove reorder directivesRené van Dorst
This requires some minimal rearranging to make work, but for the most part as does the right thing, provided we pass it an optimization flag. Suggested-by: Paul Burton <paul.burton@mips.com> Signed-off-by: René van Dorst <opensource@vdorst.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-09-20global: put SPDX identifier on its own lineJason A. Donenfeld
The kernel has very specific rules correlating file type with comment type, and also SPDX identifiers can't be merged with other comments. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-20crypto: do not waste space on selftest itemsJason A. Donenfeld
This unfortunately means we have to define symbols, since we want them in __initconst, but it's better than the other two options (no initconst or wasting space for fixed size buffers). Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-20crypto: explicitly dual licenseJason A. Donenfeld

2018-09-20poly1305: account for simd being toggled off midwayJason A. Donenfeld
This is a very rare occurance, but we should account for it, so that the calculations aren't wrong. Here we convert from base 2^26 back to base 2^64. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-20chacha20: prefer crypto_xor_cpy to avoid memmoveJason A. Donenfeld

2018-09-19poly1305: no need to trick gcc 8.1Jason A. Donenfeld
This reverts 37f114a73ba37219b00a66f0a51219a696599745, since gcc 8.2 no longer exhibits that bug. Suggested-by: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
