2019-12-06chacha20poly1305: double check the sgmiter logic with testJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2019-12-05chacha20poly1305: port to sgmitter for 5.5Jason A. Donenfeld
I'm not totally comfortable with these changes yet, and it'll require some more scrutiny. But it's a start. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

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>
2018-10-07crypto: disable broken implementations in selftestsJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-06crypto: test all SIMD combinationsJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-06global: rename include'd C files to be .cJason A. Donenfeld
This is done by 259 other files in the kernel tree: linux $ rg '#include.*\.c' -l | wc -l 259 Suggested-by: Sultan Alsawaf <sultanxda@gmail.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-03simd: introduce useful disabling macroJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-02chacha20: test multiple page span in selftestJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-10-02chacha20: break out of zero loops in selftestJason 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>
2018-09-25curve25519: show all failures in test caseJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-25chacha20: add bounds checking to selftestsJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-25crypto: make constant naming scheme consistentJason A. Donenfeld
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-25hchacha20: keep in native endian in wordsJason A. Donenfeld
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>
2018-09-20global: 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
Suggested-by: Thomas Gleixner <tglx@linutronix.de> 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>
2018-09-18chacha20: 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>
2018-09-18chacha20poly1305: add __init to selftest helper functionsJason A. Donenfeld

Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-11crypto: do not use compound literals in selftestsJason A. Donenfeld
gcc can't apply section attributes to compound literals, so we can't mark the actual data as __initconst. We thus waste space instead, but this shouldn't matter much, since it's cleared after init anyway, and because this is only for debugging. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-08poly1305: rewrite self tests from scratchJason A. Donenfeld
This removes the old cruft and makes things a bit more idiomatic. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-09-06crypto: use CRYPTOGAMS licenseJason A. Donenfeld
