Hello,<br>
<br>
A new snapshot, `0.0.20170531`, has been tagged in the git repository.<br>
<br>
Please note that this snapshot is, like the rest of the project at this point<br>
in time, experimental, and does not consitute a real release that would be<br>
considered secure and bug-free. WireGuard is generally thought to be fairly<br>
stable, and most likely will not crash your computer (though it may).<br>
However, as this is a pre-release snapshot, it comes with no guarantees, and<br>
its security is not yet to be depended on; it is not applicable for CVEs.<br>
<br>
With all that said, if you'd like to test this snapshot out, there are a<br>
few relevent changes.<br>
<br>
== Changes ==<br>
<br>
This rather large snapshot touches quite a few sensitive areas, so I'm<br>
releasing it now rather than later to receive feedback on any possible issues.<br>
It also contains fixes, so everybody should upgrade.<br>
<br>
* man: fix psk mention in wg-quick man page<br>
* man: update wg-quick(8) to show Debian resolvconf braindamage<br>
<br>
Documentation cleanups.<br>
<br>
* wg-quick: use src routing for default routes in v6<br>
<br>
ip-rule(8) doesn't do the right thing with source addresses, unless we<br>
explicitly set it inside the route. This fixes wg-quick on IPv6 systems.<br>
<br>
* curve25519: actually, do some things on heap sometimes<br>
* curve25519: align the basepoint to 32 bytes<br>
* curve25519: add NEON versions for ARM<br>
* data: enable BH during parallel crypto on ARM/NEON<br>
* chacha20poly1305: move constants to rodata<br>
* chacha20poly1305: add NEON versions for ARM and ARM64<br>
<br>
We now have faster primitives on ARM and ARM64 processors, which should<br>
improve performance.<br>
<br>
* handshake: process in parallel<br>
<br>
Handshakes are now processed in parallel using all cores, which should improve<br>
throughput during a storm.<br>
<br>
* noise: no need to store ephemeral public key<br>
* noise: precompute static-static ECDH operation<br>
<br>
We can precompute the ECDH(s, s) calculation, which improves handshake<br>
initiation message performance by double.<br>
<br>
* style: spaces after for loops<br>
* peer: use iterator macro instead of callback<br>
<br>
The most unreadable C ever produced. It might be wise to find a sexier-looking<br>
alternative at some point.<br>
<br>
* compat: remove warning for < 4.1<br>
* compat: ship padata if kernel doesn't have it<br>
<br>
The usual array of annoying compat things.<br>
<br>
* rust test: convert screech test to snow<br>
* rust test: add icmp ping<br>
<br>
We now use Jake's snow library for Noise in the test, which we've expanded to<br>
complete a ping.<br>
<br>
* config: do not error out when getting if no peers<br>
* tools: allow creating device with no peers<br>
<br>
Fixing some small things in the tool/config interaction.<br>
<br>
* device: keep going when share_check fails<br>
* routingtable: remove unnecessary check in node_placement()<br>
* config: it's faster to memcpy than strncpy<br>
* timers: fix typo in comment<br>
<br>
Nits.<br>
<br>
* debug: print interface name in dmesg<br>
<br>
For those who compile with `make debug`, you'll be happy to see a bit better<br>
information in dmesg.<br>
<br>
* timers: rework handshake reply control flow<br>
* timers: the completion of a handshake also is on key confirmation<br>
* timers: reset retry-attempt counter when not retrying<br>
<br>
Tightening up our timer implementation, which is quite important.<br>
