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>

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>

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>
