timer: refactor timers implementation #65

Closed lstipakov closed 7 months ago

lstipakov commented 7 months ago

The current implementation uses "relative" WDF timers which are "not ticked" at low power states and on resume they continue to where they were left of. This makes keepalive timeout detection sub-optimal, since in worst case a client has to wait for "ping-restart" seconds to reconnect, which could be several minutes.

Refactor timers in a way that we only have single timer ticking every second. At that tick we compare "last" and "now" timestamps and do actions, similar to what openvpn2 is doing.
