Mihai Parparita	edb02b63f8	net/sockstats: pass in logger to sockstats.WithSockStats ... Using log.Printf may end up being printed out to the console, which is not desirable. I noticed this when I was investigating some client logs with `sockstats: trace "NetcheckClient" was overwritten by another`. That turns to be harmless/expected (the netcheck client will fall back to the DERP client in some cases, which does its own sockstats trace). However, the log output could be visible to users if running the `tailscale netcheck` CLI command, which would be needlessly confusing.

Maisem Ali	be027a9899	control/controlclient: improve handling of concurrent lite map requests ... This reverts commit 6eca47b16c and fixes forward. Previously the first ever streaming MapRequest that a client sent would also set ReadOnly to true as it didn't have any endpoints and expected/relied on the map poll to restart as soon as it got endpoints. However with 48f6c1eba4, we would no longer restart MapRequests as frequently as we used to, so control would only ever get the first streaming MapRequest which had ReadOnly=true. Control would treat this as an uninteresting request and would not send it any further netmaps, while the client would happily stay in the map poll forever while litemap updates happened in parallel. This makes it so that we never set `ReadOnly=true` when we are doing a streaming MapRequest. This is no longer necessary either as most endpoint discovery happens over disco anyway.

Andrew Dunham	48f6c1eba4	control/controlclient: improve handling of concurrent lite map requests ... Prior to this change, if we were in the middle of a lite map update we'd tear down the entire map session and restart it. With this change, we'll cancel an in-flight lite map request up to 10 times and restart before we tear down the streaming map request. We tear down everything after 10 retries to ensure that a steady stream of calls to sendNewMapRequest doesn't fail to make progress by repeatedly canceling and restarting.

Mihai Parparita	6ac6ddbb47	sockstats: switch label to enum ... Makes it cheaper/simpler to persist values, and encourages reuse of labels as opposed to generating an arbitrary number. Updates tailscale/corp#9230 Updates #3363 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	9cb332f0e2	sockstats: instrument networking code paths ... Uses the hooks added by tailscale/go#45 to instrument the reads and writes on the major code paths that do network I/O in the client. The convention is to use "<package>.<type>:<label>" as the annotation for the responsible code path. Enabled on iOS, macOS and Android only, since mobile platforms are the ones we're most interested in, and we are less sensitive to any throughput degradation due to the per-I/O callback overhead (macOS is also enabled for ease of testing during development). For now just exposed as counters on a /v0/sockstats PeerAPI endpoint. We also keep track of the current interface so that we can break out the stats by interface.

Brad Fitzpatrick	fb4e23506f	control/controlclient: stop restarting map polls on health change ... At some point we started restarting map polls on health change, but we don't remember why. Maybe it was a desperate workaround for something. I'm not sure it ever worked. Rather than have a haunted graveyard, remove it. In its place, though, and somewhat as a safety backup, send those updates over the HTTP/2 noise channel if we have one open. Then if there was a reason that a map poll restart would help we could do it server-side. But mostly we can gather error stats and show machine-level health info for debugging.

Maisem Ali	c60cbca371	control/controlclient: store netinfo and hostinfo separately ... Currently, when SetNetInfo is called it sets the value on hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the hostinfo field which may mean it also clears out the NetInfo it had just received. This commit stores NetInfo separately and combines it into Hostinfo as needed so that control is always notified of the latest values.

Avery Pennarun	8a7d35594d	ipnlocal: don't assume NeedsLogin immediately after StartLogout(). ... Previously, there was no server round trip required to log out, so when you asked ipnlocal to Logout(), it could clear the netmap immediately and switch to NeedsLogin state. In v1.8, we added a true Logout operation. ipn.Logout() would trigger an async cc.StartLogout() and *also* immediately switch to NeedsLogin. Unfortunately, some frontends would see NeedsLogin and immediately trigger a new StartInteractiveLogin() operation, before the controlclient auth state machine actually acted on the Logout command, thus accidentally invalidating the entire logout operation, retaining the netmap, and violating the user's expectations. Instead, add a new LogoutFinished signal from controlclient (paralleling LoginFinished) and, upon starting a logout, don't update the ipn state machine until it's received.

Brad Fitzpatrick	34d2f5a3d9	tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType ... Track endpoints internally with a new tailcfg.Endpoint type that includes a typed netaddr.IPPort (instead of just a string) and includes a type for how that endpoint was discovered (STUN, local, etc). Use []tailcfg.Endpoint instead of []string internally. At the last second, send it to the control server as the existing []string for endpoints, but also include a new parallel MapRequest.EndpointType []tailcfg.EndpointType, so the control server can start filtering out less-important endpoint changes from new-enough clients. Notably, STUN-discovered endpoints can be filtered out from 1.6+ clients, as they can discover them amongst each other via CallMeMaybe disco exchanges started over DERP. And STUN endpoints change a lot, causing a lot of MapResposne updates. But portmapped endpoints are worth keeping for now, as they they work right away without requiring the firewall traversal extra RTT dance. End result will be less control->client bandwidth.

Brad Fitzpatrick	2f04f49376	control/controlclient: use lite map request handler to avoid aborting streams ... Previously, any change to endpoints or hostinfo (or hostinfo's netinfo) would result in the long-running map request HTTP stream being torn down and restarted, losing all compression context along with it. This change makes us instead send a lite map request (OmitPeers: true, Stream: false) that doesn't subscribe to anything, and then the coordination server knows to not close other streams for that node when it recives a lite request.
