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.

Brad Fitzpatrick	04c2c5bd80	net/interfaces: define DefaultRouteInterface and State.DefaultRouteInterface It was pretty ill-defined before and mostly for logging.

Brad Fitzpatrick	434af15a04	derp: support client->server ping (and server->client pong) In prep for a future change to have client ping derp connections when their state is questionable, rather than aggressively tearing them down and doing a heavy reconnect when their state is unknown. We already support ping/pong in the other direction (servers probing clients) so we already had the two frame types, but I'd never finished this direction.

Brad Fitzpatrick	3dedcd1640	logpolicy, ipn/ipnserver: connect to logtail via tailscaled when needed This is for use by the Windows GUI client to log via when an exit node is in use, so the logs don't go out via the exit node and instead go directly, like tailscaled's. The dialer tried to do that in the unprivileged GUI by binding to a specific interface, but the "Internet Kill Switch" installed by tailscaled for exit nodes precludes that from working and instead the GUI fails to dial out. So, go through tailscaled (with a CONNECT request) instead.

Brad Fitzpatrick	5a9914a92f	wgengine/netstack: don't remove 255.255.255.255/32 from netstack The intent of the updateIPs code is to add & remove IP addresses to netstack based on what we get from the netmap. But netstack itself adds 255.255.255.255/32 apparently and we always fight it (and it adds it back?). So stop fighting it. Updates #2642 (maybe fixes? maybe.)

Brad Fitzpatrick	40e2b312b6	ipn/ipnserver, logpolicy: move Windows disk logging up earlier This moves the Windows-only initialization of the filelogger into logpolicy. Previously we only did it when babysitting the tailscaled subprocess, but this meant that log messages from the service itself never made it to disk. Examples that weren't logged to disk: * logtail unable to dial out, * DNS flush messages from the service * svc.ChangeRequest messages (#3581) This is basically the same fix as #3571 but staying in the Logf type, and avoiding build-tagged file (which wasn't quite a goal, but happened and seemed nice) Fixes #3570 Co-authored-by: Aaron Klotz <aaron@tailscale.com> Change-Id: Iacd80c4720b7218365ec80ae143339d030842702	3 years ago
