Brad Fitzpatrick	3af051ea27	control/controlclient, types/netmap: start plumbing delta netmap updates Currently only the top four most popular changes: endpoints, DERP home, online, and LastSeen. Updates #1909 Change-Id: I03152da176b2b95232b56acabfb55dcdfaa16b79 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	42072683d6	control/controlknobs: move ForceBackgroundSTUN to controlknobs.Knobs This is both more efficient (because the knobs' bool is only updated whenever Node is changed, rarely) and also gets us one step closer to removing a case of storing a netmap.NetworkMap in magicsock. (eventually we want to phase out much of the use of that type internally) Updates #1909 Change-Id: I37e81789f94133175064fdc09984e4f3a431f1a1 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	4e91cf20a8	control/controlknobs, all: add plumbed Knobs type, not global variables Previously two tsnet nodes in the same process couldn't have disjoint sets of controlknob settings from control as both would overwrite each other's global variables. This plumbs a new controlknobs.Knobs type around everywhere and hangs the knobs sent by control on that instead.

Brad Fitzpatrick	9a86aa5732	all: depend on zstd unconditionally, remove plumbing to make it optional All platforms use it at this point, including iOS which was the original hold out for memory reasons. No more reason to make it optional. Updates #9332 Change-Id: I743fbc2f370921a852fbcebf4eb9821e2bdd3086 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Maisem Ali	d06a75dcd0	ipn/ipnlocal: fix deadlock in resetControlClientLocked resetControlClientLocked is called while b.mu was held and would call cc.Shutdown which would wait for the observer queue to drain. However, there may be active callbacks from cc already waiting for b.mu resulting in a deadlock. This makes it so that resetControlClientLocked does not call Shutdown, and instead just returns the value. It also makes it so that any status received from previous cc are ignored.

Brad Fitzpatrick	55bb7314f2	control/controlclient: replace a status func with Observer interface For now the method has only one interface (the same as the func it's replacing) but it will grow, eventually with the goal to remove the controlclient.Status type for most purposes.

Brad Fitzpatrick	b5ff68a968	control/controlclient: flesh out mapSession to break up gigantic method Now mapSession has a bunch more fields and methods, rather than being just one massive func with a ton of local variables. So far there are no major new optimizations, though. It should behave the same as before. This has been done with an eye towards testability (so tests can set all the callback funcs as needed, or not, without a huge Direct client or long-running HTTP requests), but this change doesn't add new tests yet. That will follow in the changes which flesh out the NetmapUpdater interface.

Brad Fitzpatrick	7dec09d169	control/controlclient: remove Opts.KeepSharerAndUserSplit It was added 2.5 years ago in `c1dabd9436` but was never used. Clearly that migration didn't matter. We can attempt this again later if/when this matters. Meanwhile this simplifies the code and thus makes working on other current efforts in these parts of the code easier.

Brad Fitzpatrick	25663b1307	tailcfg: remove most Debug fields, move bulk to nodeAttrs [capver 70] Now a nodeAttr: ForceBackgroundSTUN, DERPRoute, TrimWGConfig, DisableSubnetsIfPAC, DisableUPnP. Kept support for, but also now a NodeAttr: RandomizeClientPort. Removed: SetForceBackgroundSTUN, SetRandomizeClientPort (both never used, sadly... never got around to them. But nodeAttrs are better anyway), EnableSilentDisco (will be a nodeAttr later when that effort resumes). Updates #8923 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Brad Fitzpatrick	2398993804	control/controlclient: refactor in prep for optimized delta handling See issue. This is a baby step towards passing through deltas end-to-end from node to control back to node and down to the various engine subsystems, not computing diffs from two full netmaps at various levels. This will then let us support larger netmaps without burning CPU. But this change itself changes no behavior. It just changes a func type to an interface with one method. That paves the way for future changes to then add new NetmapUpdater methods that do more fine-grained work than updating the whole world.

Maisem Ali	d16946854f	control/controlclient: add Auto.updateRoutine Instead of having updates replace the map polls, create a third goroutine which is solely responsible for making sure that control is aware of the latest client state. This also makes it so that the streaming map polls are only broken when there are auth changes, or the client is paused.

Maisem Ali	734928d3cb	control/controlclient: make Direct own all changes to Persist It was being modified in two places in Direct for the auth routine and then in LocalBackend when a new NetMap was received.

Maisem Ali	60e5761d60	control/controlclient: reset backoff in mapRoutine on netmap recv We were never resetting the backoff in streaming mapResponses.

Andrew Dunham	42fd964090	control/controlclient: use dnscache.Resolver for Noise client This passes the *dnscache.Resolver down from the Direct client into the Noise client and from there into the controlhttp client.

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.

Mihai Parparita	9a655a1d58	net/dnsfallback: more explicitly pass through logf function Redoes the approach from #5550 and #7539 to explicitly pass in the logf function, instead of having global state that can be overridden. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

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	3a018e51bb	ipn/ipnlocal: move handling of expired nodes to LocalBackend In order to be able to synthesize a new NetMap when a node expires, have LocalBackend start a timer when receiving a new NetMap that fires slightly after the next node expires.

Maisem Ali	235309adc4	all: store NL keys per profile This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct. This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey. It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional to be able to delete the "/tka" dir if it exists. This means that we will have a unique key per profile, and a unique directory per profile. Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not delete the ChonkDir. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Brad Fitzpatrick	3f8e185003	health: add Warnable, move ownership of warnable items to callers The health package was turning into a rando dumping ground. Make a new Warnable type instead that callers can request an instance of, and then Set it locally in their code without the health package being aware of all the things that are warnable. (For plenty of things the health package will want to know details of how Tailscale works so it can better prioritize/suppress errors, but lots of the warnings are pretty leaf-y and unrelated) This just moves two of the health warnings. Can probably move more later. Change-Id: I51e50e46eb633f4e96ced503d3b18a1891de1452 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

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.
