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>

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>

2018-08-07curve25519-hacl64: correct u64_gte_maskSamuel Neves
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. Donenfeld <Jason@zx2c4.com>
2018-08-07curve25519-hacl64: simplify u64_eq_maskSamuel Neves
Avoid signed right shift. Z3 script showing equivalence: >>> from z3 import * >>> >>> x = BitVec("x", 64) >>> y = BitVec("y", 64) >>> >>> # Before ... x_ = ~(x ^ y) >>> x_ &= x_ << 32 >>> x_ &= x_ << 16 >>> x_ &= x_ << 8 >>> x_ &= x_ << 4 >>> x_ &= x_ << 2 >>> x_ &= x_ << 1 >>> x_ >>= 63 >>> >>> # After ... y_ = x ^ y >>> y_ = y_ | -y_ >>> y_ = LShR(y_, 63) - 1 >>> >>> prove(x_ == y_) proved Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A.

2018-08-04send: switch handshake stamp to an atomicJason A. Donenfeld
Rather than abusing the handshake lock, we're much better off just using a boring atomic64 for this. It's simpler and performs better. Also, while we're at it, we set the handshake stamp both before and after the calculations, in case the calculations block for a really long time waiting for the RNG to initialize. Otherwise it's possible that when the RNG finally initializes, two handshakes are sent back to back, which isn't sensible. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
