2018-09-11crypto: do not use compound literals in selftestsJason A. Donenfeld2-7704/+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.

It makes extending things more difficult.
2018-09-02netlink: insert peer version placeholderJason A. Donenfeld3-3/+17
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. Donenfeld1-6/+19
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.
2018-08-28crypto: use unaligned helpersJason A. Donenfeld9-55/+61
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.

2018-08-28global: run through clang-formatJason A. Donenfeld28-795/+1654
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.

2018-08-12wg-quick: darwin: prefer system paths for toolsJason A. Donenfeld1-1/+1
The only things wg-quick(8) needs from Homebrew are bash(1) and wg(8). Other than that, it's explicitly coded against the native system utilities. Since wg-quick(8) and bash(1) are invoked in auto_su by their full absolute path (via $SELF and $BASH, respectively), we can simply set the $PATH to be prefixed by the default system binary paths. This way, if users install tools that conflict with system tools -- such as GNU coreutils -- we won't accidently call those. Reported-by: Deirdre Connolly <durumcrustulum@gmail.com>

2018-08-07curve25519-hacl64: correct u64_gte_maskSamuel Neves1-3/+1
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>
2018-08-07curve25519-hacl64: simplify u64_eq_maskSamuel Neves1-8/+3
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>

This causes problems with RAP and KERNEXEC for PaX, as r12 is a reserved register. Suggested-by: PaX Team <pageexec@freemail.hu>

2018-08-04send: switch handshake stamp to an atomicJason A. Donenfeld4-14/+12
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.

Completely rework peer removal to ensure peers don't jump between contexts and create races.

2018-08-02cookie: returned keypair might disappear if rcu lock not heldJason A. Donenfeld2-14/+19
And in general it's good to prefer dereferencing entry.peer from a handshake object rather than a keypair object, when possible, since keypairs could disappear before their underlying peer.
2018-08-02queueing: ensure strictly ordered loads and storesJason A. Donenfeld4-5/+33
We don't want a consumer to read plaintext when it's supposed to be reading ciphertext, which means we need to synchronize across cores. Suggested-by: Jann Horn <jann@thejh.net>
