Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-23chacha20-arm: updated scalar code from AndyJason A. Donenfeld

2018-09-23poly1305-mips64: remove useless preprocessor errorJason 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>
2018-09-23allowedips: work around kasan stack frame bug in selftestJason A. Donenfeld
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
Signed-off-by: René van Dorst <opensource@vdorst.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
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>
2018-09-21chacha20-mips32r2: fix typo to allow reorder againRené van Dorst

2018-09-21poly1305-mips32r2: remove all reorder directivesRené van Dorst

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>
2018-09-20ratelimiter: disable selftest with KASANJason A. Donenfeld
This this relies on instructions taking a "normal" amount of time, we really can't run this with KASAN, especially inside QEMU, so just disable it for KASAN, since it's hard to make it complete on slow systems. 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>
2018-09-20netlink: reverse my christmas treesJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

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>
2018-09-20allowedips: change from BUG_ON to WARN_ONJason A. Donenfeld
This is never going to hit anyway, and if it does, it's a development problem that will be caught with the selftests anyway. So don't make Andrew Lunn upset, and just change it to a WARN_ON. Suggested-by: Andrew Lunn <andrew@lunn.ch> 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>

2018-09-18chacha20: add independent self testJason A. Donenfeld
This was already tested from the chacha20poly1305 test, but it's useful to be able to test this in isolation too. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
