2018-05-20Fix race with closing event channelJason A. Donenfeld
There's still a tiny race on Linux, since the tun channel is written to from two places.

2018-05-19timers: no need to clear keepalive in persistent keepaliveJason A. Donenfeld
We do this after sending the keepalive anyway. This is something of a regression, though, since before we'd cancel and then send, but now we send and then cancel, so it introduces a potential race, but hopefully that isn't too big of a deal. Kernel module commit a24b3e6e15ae1ea1291666e5da910caf43eedbaf
2018-05-19timers: clear send_keepalive timer on sending handshake responseJason A. Donenfeld
We reorganize this into also doing so on sending keepalives itself, which means the state machine is much more consistent, even if this was already implied. Kernel module commit 30290ef1d2581a3e6ee8ffcdb05d580cfba976be
2018-05-19Listen for flush in outer selectMathias Hall-Andersen
Now listen for flushNonceQueue signal in outer select during the RoutineNonce routine. This is needed to handle the edge case where the queue is flushed, but no packets are in the nonce queue. Since the signal has capacity 1 this signal will remain and potentially flush the queue at a later time, with packets meant for transmission.
