History

Brad Fitzpatrick 28bf53f502 wgengine/magicsock: reduce disco ping heartbeat aggressiveness a bit Bigger changes coming later, but this should improve things a bit in the meantime. Rationale: * 2 minutes -> 45 seconds: 2 minutes was overkill and never considered phones/battery at the time. It was totally arbitrary. 45 seconds is also arbitrary but is less than 2 minutes. * heartbeat from 2 seconds to 3 seconds: in practice this meant two packets per second (2 pings and 2 pongs every 2 seconds) because the other side was also pinging us every 2 seconds on their own. That's just overkill. (see #540 too) So in the worst case before: when we sent a single packet (say: a DNS packet), we ended up sending 61 packets over 2 minutes: the 1 DNS query and then then 60 disco pings (2 minutes / 2 seconds) & received the same (1 DNS response + 60 pongs). Now it's 15. In 1.22 we plan to remove this whole timer-based heartbeat mechanism entirely. The 5 seconds to 6.5 seconds change is just stretching out that interval so you can still miss two heartbeats (other 3 + 3 seconds would be greater than 5 seconds). This means that if your peer moves without telling you, you can have a path out for 6.5 seconds now instead of 5 seconds before disco finds a new one. That will also improve in 1.22 when we start doing UDP+DERP at the same time when confidence starts to go down on a UDP path.
