-----BEGIN PGP SIGNED MESSAGE-----
A new snapshot, `0.0.20180809`, has been tagged in the git repository.
Please note that this snapshot is, like the rest of the project at this point
in time, experimental, and does not consitute a real release that would be
considered secure and bug-free. WireGuard is generally thought to be fairly
stable, and most likely will not crash your computer (though it may).
However, as this is a pre-release snapshot, it comes with no guarantees, and
its security is not yet to be depended on; it is not applicable for CVEs.
With all that said, if you'd like to test this snapshot out, there are a
few relevent changes.
== Changes ==
* send: switch handshake stamp to an atomic
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.
* compat: better atomic acquire/release backport
This should fix compilation and correctness on several platforms.
* crypto: move simd context to specific type
This was a suggestion from Andy Lutomirski on LKML.
* chacha20poly1305: selftest: use arrays for test vectors
We no longer have lines so long that they're rejected by SMTP servers.
* qemu: add easy git harness
This makes it a bit easier to use our qemu harness for testing our mainline
* curve25519-x86_64: avoid use of r12
This causes problems with RAP and KERNEXEC for PaX, as r12 is a
* chacha20: use memmove in case buffers overlap
A small correctness fix that we never actually hit in WireGuard but is
important especially for moving this into a general purpose library.
* curve25519-hacl64: simplify u64_eq_mask
* curve25519-hacl64: correct u64_gte_mask
Two bitmath fixes from Samuel, which come complete with a z3 script proving
* timers: include header in right file
This fixes compilation in some environments.
* netlink: don't start over iteration on multipart non-first allowedips
Matt Layher found a bug where a netlink dump of peers would never terminate in
some circumstances, causing wg(8) to keep trying forever. We now have a fix as
well as a unit test to mitigate this, and we'll be looking to create a fuzzer
out of Matt's nice library.
