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>

2018-09-02netlink: insert peer version placeholderJason A. Donenfeld
While we don't want people to ever use old protocols, people will complain if the API "changes", so explicitly make the unset protocol mean the latest, and add a dummy mechanism of specifying the protocol on a per-peer basis, which we hope nobody actually ever uses.

2018-08-28curve25519-hacl64: use formally verified C for comparisonsJason A. Donenfeld
The previous code had been proved in Z3, but this new code from upstream KreMLin is directly generated from the F*, which is preferable. The assembly generated is identical. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2018-08-28crypto: use unaligned helpersJason A. Donenfeld
This is not useful for WireGuard, but for the general use case we probably want it this way, and the speed difference is mostly lost in the noise. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2018-08-28global: run through clang-formatJason A. Donenfeld
This is the worst commit in the whole repo, making the code much less readable, but so it goes with upstream maintainers. We are now woefully wrapped at 80 columns. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

Remove signed right shifts. Previously u64_gte_mask was only correct for x < 2^63. Z3 script proving correctness: >>> from z3 import * >>> >>> x = BitVec("x", 64) >>> y = BitVec("y", 64) >>> >>> t = LShR(x^((x^y)|((x-y)^y)), 63) - 1 >>> >>> prove(If(UGE(x, y), BitVecVal(-1, 64), BitVecVal(0, 64)) == t) proved Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A.
