* chacha20-arm: go with Ard's version to optimize for Cortex-A7Jason A. Donenfeld2018-09-216-682/+549
| | | | Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* chacha20-mips32r2: remove reorder directivesRené van Dorst2018-09-212-106/+68
| | | | | | | | | 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.

* poly1305-mips32r2: remove all reorder directivesRené van Dorst2018-09-212-32/+23
| | | | | | | | | 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.

* global: put SPDX identifier on its own lineJason A. Donenfeld2018-09-2076-152/+152
| | | | | | | 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>
* ratelimiter: disable selftest with KASANJason A. Donenfeld2018-09-201-0/+4
| | | | | | | | | 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>
* crypto: do not waste space on selftest itemsJason A. Donenfeld2018-09-203-9458/+10993
| | | | | | | | 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>
* netlink: reverse my christmas treesJason A. Donenfeld2018-09-201-10/+11

* poly1305: account for simd being toggled off midwayJason A. Donenfeld2018-09-203-26/+131
| | | | | | | | 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>
* allowedips: change from BUG_ON to WARN_ONJason A. Donenfeld2018-09-202-3/+3
| | | | | | | | | 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>
* chacha20: prefer crypto_xor_cpy to avoid memmoveJason A. Donenfeld2018-09-202-5/+31

* poly1305: no need to trick gcc 8.1Jason A. Donenfeld2018-09-191-2/+2
| | | | | | | | 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>

* chacha20: add independent self testJason A. Donenfeld2018-09-182-0/+1188
| | | | | | | 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>

* crypto: do not use compound literals in selftestsJason A. Donenfeld2018-09-112-7704/+7710
| | | | | | | | | 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>
