Anton Tolchanov	32120932a5	cmd/tailscale/cli: print node signature in `tailscale lock status` - Add current node signature to `ipnstate.NetworkLockStatus`; - Print current node signature in a human-friendly format as part of `tailscale lock status`. Examples: ``` $ tailscale lock status Tailnet lock is ENABLED. This node is accessible under tailnet lock.

Andrew Lytvynov	776a05223b	ipn/ipnlocal: support c2n updates with old systemd versions (#12296 ) The `--wait` flag for `systemd-run` was added in systemd 232. While it is quite old, it doesn't hurt to special-case them and skip the `--wait` flag. The consequence is that we lose the update command output in logs, but at least auto-updates will work.

Andrew Lytvynov	c9179bc261	various: disable stateful filtering by default (#12197 ) After some analysis, stateful filtering is only necessary in tailnets that use `autogroup:danger-all` in `src` in ACLs. And in those cases users explicitly specify that hosts outside of the tailnet should be able to reach their nodes. To fix local DNS breakage in containers, we disable stateful filtering by default.

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.

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.

Anton Tolchanov	31e6bdbc82	ipn/ipnlocal: always stop the engine on auth when key has expired If seamless key renewal is enabled, we typically do not stop the engine (deconfigure networking). However, if the node key has expired there is no point in keeping the connection up, and it might actually prevent key renewal if auth relies on endpoints routed via app connectors.

Andrew Lytvynov	06502b9048	ipn/ipnlocal: reset auto-updates if unsupported on profile load (#11838 ) Prior to `1613b18f82 (diff-314ba0d799f70c8998940903efb541e511f352b39a9eeeae8d475c921d66c2ac)`, nodes could set AutoUpdate.Apply=true on unsupported platforms via `EditPrefs`. Specifically, this affects tailnets where default auto-updates are on. Fix up those invalid prefs on profile reload, as a migration.

Andrew Lytvynov	b743b85dad	ipn/ipnlocal,ssh/tailssh: reject c2n /update if SSH conns are active (#11820 ) Since we already track active SSH connections, it's not hard to proactively reject updates until those finish. 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. Handle a `force=true` query parameter to override this behavior, so that control can still trigger an update on a server where some long-running abandoned SSH session is open.
