Brad Fitzpatrick	1384c24e41	control/controlclient: delete unused Client.Login Oauth2Token field ... Updates #12172 (then need to update other repos) Change-Id: I439f65e0119b09e00da2ef5c7a4f002f93558578 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 months ago
Brad Fitzpatrick	e968b0ecd7	cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more ... The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda chaotic and they both need to be redone/deleted (respectively), but this fixes some buggy behavior meanwhile. We were previously calling StartLoginInteractive (to start the controlclient's RegisterRequest) redundantly in some cases, causing test flakes depending on timing and up's weird state machine. We only need to call StartLoginInteractive in the client if Start itself doesn't. But Start doesn't tell us that. So cheat a bit and a put the information about whether there's a current NodeKey in the ipn.Status. It used to be accessible over LocalAPI via GetPrefs as a private key but we removed that for security. But a bool is fine. So then only call StartLoginInteractive if that bool is false and don't do it in the WatchIPNBus loop.

Brad Fitzpatrick	3672f29a4e	net/netns, net/dns/resolver, etc: make netmon required in most places ... The goal is to move more network state accessors to netmon.Monitor where they can be cheaper/cached. But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 months ago

Brad Fitzpatrick	723c775dbb	tsd, ipnlocal, etc: add tsd.System.HealthTracker, start some plumbing ... This adds a health.Tracker to tsd.System, accessible via a new tsd.System.HealthTracker method. In the future, that new method will return a tsd.System-specific HealthTracker, so multiple tsnet.Servers in the same process are isolated. For now, though, it just always returns the temporary health.Global value. That permits incremental plumbing over a number of changes. When the second to last health.Global reference is gone, then the tsd.System.HealthTracker implementation can return a private Tracker. The primary plumbing this does is adding it to LocalBackend and its dozen and change health calls. A few misc other callers are also plumbed. Subsequent changes will flesh out other parts of the tree (magicsock, controlclient, etc).

Brad Fitzpatrick	ebc552d2e0	health: add Tracker type, in prep for removing global variables ... This moves most of the health package global variables to a new `health.Tracker` type. But then rather than plumbing the Tracker in tsd.System everywhere, this only goes halfway and makes one new global Tracker (`health.Global`) that all the existing callers now use. A future change will eliminate that global. Updates #11874 Updates #4136 Change-Id: I6ee27e0b2e35f68cb38fecdb3b2dc4c3f2e09d68 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 months ago

James Tucker	9401b09028	control/controlclient: move client watchdog to cover initial request ... The initial control client request can get stuck in the event that a connection is established but then lost part way through, without any ICMP or RST.

Brad Fitzpatrick	8444937c89	control/controlclient: fix panic regression from earlier load balancer hint header ... In the recent 20e9f3369 we made HealthChangeRequest machine requests include a NodeKey, as it was the oddball machine request that didn't include one. Unfortunately, that code was sometimes being called (at least in some of our integration tests) without a node key due to its registration with health.RegisterWatcher(direct.ReportHealthChange). Fortunately tests in corp caught this before we cut a release. It's possible this only affects this particular integration test's environment, but still worth fixing.

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491) ... Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

Brad Fitzpatrick	44c6909c92	control/controlclient: move watchdog out of mapSession ... In prep for making mapSession's lifetime not be 1:1 with a single HTTP response's lifetime, this moves the inactivity timer watchdog out of mapSession and into the caller that owns the streaming HTTP response. (This is admittedly closer to how it was prior to the mapSession type existing, but that was before we connected some dots which were impossible to even see before the mapSession type broke the code up.)

Brad Fitzpatrick	c87d58063a	control/controlclient: move lastPrintMap field from Direct to mapSession ... It was a really a mutable field owned by mapSession that we didn't move in earlier commits. Once moved, it's then possible to de-func-ify the code and turn it into a regular method rather than an installed optional hook. Noticed while working to move map session lifetimes out of Direct.sendMapRequest's single-HTTP-connection scope.

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.

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	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	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.
