* cookies: use xchacha20poly1305 instead of chacha20poly1305Jason A. Donenfeld2016-12-231-4/+14
| | | | | This allows us to precompute the blake2s calls and save cycles, since hchacha is fast.

* timers: upstream removed the slack conceptJason A. Donenfeld2016-07-231-5/+2
| | | | | No longer do we specify slack ourselves. Instead we need to add it directly in the main scheduling.
* timers: apply slack to hotpath timersJason A. Donenfeld2016-07-101-2/+5
| | | | | | | | | | | For timers in the hotpath, we don't want them to be rescheduled so aggressively, and since they don't need to be that precise, we can set a decent amount of slack. With the persistent keepalive timer, we have something of a special case. Since the timeout isn't fixed like the others, we don't want to make it more often than the kernel ordinarily would. So, instead, we make it a minimum.

* persistent keepalive: start sending immediatelyexperimental-0.0.20160708.1Jason A. Donenfeld2016-07-081-1/+4
| | | | | | | | | | | | | | | Rather than only start sending the persistent keepalive packets when the device first sends data, this changes it to send the packets immediately on `ip link set up`. This makes things generally seem more stateless, since the administrator does not have to manually ping the endpoint. Of course, if you have a lot of peers and all of them have persistent keepalive enabled, this could cause a lot of unwanted immediate traffic. On the other hand, if all of those peers are at some point going to be sending packets, this would happen anyway. I suppose the moral of the story is that persistent keepalive is a feature really just for clients behind NAT, not for servers, and it should be used sparingly, which is why we've set it off by default in the first place.
