Brad Fitzpatrick	964282d34f	ipn,wgengine: remove vestigial Prefs.AllowSingleHosts It was requested by the first customer 4-5 years ago and only used for a brief moment of time. We later added netmap visibility trimming which removes the need for this. It's been hidden by the CLI for quite some time and never documented anywhere else. This keeps the CLI flag, though, out of caution. It just returns an error if it's set to anything but true (its default).

Brad Fitzpatrick	8aa5c3534d	ipn/ipnlocal: simplify authURL vs authURLSticky, remove interact field The previous LocalBackend & CLI 'up' changes improved some stuff, but might've been too aggressive in some edge cases. This simplifies the authURL vs authURLSticky distinction and removes the interact field, which seemed to just just be about duplicate URL suppression in IPN bus, back from when the IPN bus was a single client at a time. This moves that suppression to a different spot.

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.

Nick Khyl	caa3d7594f	ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP. This is primarily necessary to properly dial internal DNS servers accessible over Tailscale and subnet routes. However, to avoid issues when switching between Wi-Fi and cellular, we need to ensure that we don't retain connections to any external addresses on the old interface. Therefore, we need to determine which dialer to use internally based on the configured routes. This plumbs routes and localRoutes from router.Config to tsdial.Dialer, and updates UserDial to use either the peer dialer or the system dialer, depending on the network address and the configured routes.

If it is not reset here, dial plans returned by old server (e.g. tailscale control server) will be used to connect to new server (e.g. self-hosted headscale server), and the register request will be blocked by it until timeout, leading to very slow profile switches.

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.

We attempt to do the same on the control side, but the detection latency for new connections is in the minutes, which is not fast enough for common short sessions.

Brad Fitzpatrick	aa084a29c6	ipn/ipnlocal: name the unlockOnce type, plumb more, add Unlock method This names the func() that Once-unlocked LocalBackend.mu. It does so both for docs and because it can then have a method: Unlock, for the few points that need to explicitly unlock early (the cause of all this mess). This makes those ugly points easy to find, and also can then make them stricter, panicking if the mutex is already unlocked. So a normal call to the func just once-releases the mutex, returning false if it's already done, but the Unlock method is the strict one. Then this uses it more, so most the b.mu.Unlock calls remaining are simple cases and usually defers.

Brad Fitzpatrick	5e7c0b025c	ipn/ipnlocal: add some "lockedOnEntry" helpers + guardrails, fix bug A number of methods in LocalBackend (with suffixed "LockedOnEntry") require b.mu be held but unlock it on the way out. That's asymmetric and atypical and error prone. This adds a helper method to LocalBackend that locks the mutex and returns a sync.OnceFunc that unlocks the mutex. Then we pass around that unlocker func down the chain to make it explicit (and somewhat type check the passing of ownership) but also let the caller defer unlock it, in the case of errors/panics that happen before the callee gets around to calling the unlock. This revealed a latent bug in LocalBackend.DeleteProfile which double unlocked the mutex.

Brad Fitzpatrick	7b34154df2	all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89] First we had Capabilities []string. Then https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a superset of Capabilities. Except we never really finished the transition inside the codebase to go all-in on CapMap. This does so. Notably, this coverts Capabilities on the wire early to CapMap internally so the code can only deal in CapMap, even against an old control server. In the process, this removes PeerChange.Capabilities support, which no known control plane sent anyway. They can and should use PeerChange.CapMap instead.

Percy Wegmann	2d5d6f5403	ipn,wgengine: only intercept TailFS traffic on quad 100 This fixes a regression introduced with `993acf4` and released in v1.60.0.

Now, we only intercept traffic to port 8080 if it's bound for 100.100.100.100 or fd7a:115c:a1e0::53.

Andrea Gottardo	6c79f55d48	ipnlocal: force-regen new authURL when it is too old (#10971 ) Fixes tailscale/support-escalations#23. authURLs returned by control expire after 1 hour from creation. Customer reported that the Tailscale client on macOS would sending users to a stale authentication page when clicking on the `Login...` menu item. This can happen when clicking on Login after leaving the device unattended for several days. The device key expires, leading to the creation of a new authURL, however the client doesn't keep track of when the authURL was created. Meaning that `login-interactive` would send the user to an authURL that had expired server-side a long time before. This PR ensures that whenever `login-interactive` is called via LocalAPI, an authURL that is too old won't be used. We force control to give us a new authURL whenever it's been more than 30 minutes since the last authURL was sent down from control.

Jordan Whited	8b47322acc	wgengine/magicsock: implement probing of UDP path lifetime (#10844 ) This commit implements probing of UDP path lifetime on the tail end of an active direct connection. Probing configuration has two parts - Cliffs, which are various timeout cliffs of interest, and CycleCanStartEvery, which limits how often a probing cycle can start, per-endpoint. Initially a statically defined default configuration will be used. The default configuration has cliffs of 10s, 30s, and 60s, with a CycleCanStartEvery of 24h. Probing results are communicated via clientmetric counters. Probing is off by default, and can be enabled via control knob. Probing is purely informational and does not yet drive any magicsock behaviors. Updates #540 Signed-off-by: Jordan Whited <jordan@tailscale.com>	10 months ago

Will Norris	236531c5fc	ipn/ipnserver: always allow Windows SYSTEM user to connect When establishing connections to the ipnserver, we validate that the local user is allowed to connect. If Tailscale is currently being managed by a different user (primarily for multi-user Windows installs), we don't allow the connection. With the new device web UI, the inbound connection is coming from tailscaled itself, which is often running as "NT AUTHORITY\SYSTEM". In this case, we still want to allow the connection, even though it doesn't match the user running the Tailscale GUI. The SYSTEM user has full access to everything on the system anyway, so this doesn't escalate privileges. Eventually, we want the device web UI to run outside of the tailscaled process, at which point this exception would probably not be needed.
