Andrea Gottardo	a8ee83e2c5	health: begin work to use structured health warnings instead of strings, pipe changes into ipn.Notify (#12406 ) Updates tailscale/tailscale#4136 This PR is the first round of work to move from encoding health warnings as strings and use structured data instead. The current health package revolves around the idea of Subsystems. Each subsystem can have (or not have) a Go error associated with it. The overall health of the backend is given by the concatenation of all these errors. This PR polishes the concept of Warnable introduced by @bradfitz a few weeks ago. Each Warnable is a component of the backend (for instance, things like 'dns' or 'magicsock' are Warnables). Each Warnable has a unique identifying code. A Warnable is an entity we can warn the user about, by setting (or unsetting) a WarningState for it. Warnables have: - an identifying Code, so that the GUI can track them as their WarningStates come and go - a Title, which the GUIs can use to tell the user what component of the backend is broken - a Text, which is a function that is called with a set of Args to generate a more detailed error message to explain the unhappy state Additionally, this PR also begins to send Warnables and their WarningStates through LocalAPI to the clients, using ipn.Notify messages. An ipn.Notify is only issued when a warning is added or removed from the Tracker. In a next PR, we'll get rid of subsystems entirely, and we'll start using structured warnings for all errors affecting the backend functionality.

Brad Fitzpatrick	dd6c76ea24	ipn: remove unused Options.LegacyMigrationPrefs I'm on a mission to simplify LocalBackend.Start and its locking and deflake some tests. I noticed this hasn't been used since March 2023 when it was removed from the Windows client in corp 66be796d33c. So, delete.

Marwan Sulaiman	a4aa6507fa	ipn, ipn/ipnlocal: add session identifier for WatchIPNBus This PR adds a SessionID field to the ipn.Notify struct so that ipn buses can identify a session and register deferred clean up code in the future.

Brad Fitzpatrick	06c4c47d46	ipn: remove unused Backend interface Only the macOS/iOS clients care about it still, so we'll move it to their repo.

Brad Fitzpatrick	5676d201d6	ipn: add a WatchIPNBus option bit to subscribe to EngineStatus changes So GUI clients don't need to poll for it.

Avery Pennarun	6d10655dc3	ipnlocal: accept a new opts.UpdatePrefs field. This is needed because the original opts.Prefs field was at some point subverted for use in frontend->backend state migration for backward compatibility on some platforms. We still need that feature, but we also need the feature of providing the full set of prefs from `tailscale up`, not including overwriting the prefs.Persist keys, so we can't use the original field from `tailscale up`. `tailscale up` had attempted to compensate for that by doing SetPrefs() before Start(), but that violates the ipn.Backend contract, which says you should call Start() before anything else (that's why it's called Start()). As a result, doing SetPrefs({ControlURL=..., WantRunning=true}) would cause a connection to the previous control server (because WantRunning=true), and then connect to the new control server only after running Start(). This problem may have been avoided before, but only by pure luck. It turned out to be relatively harmless since the connection to the old control server was immediately closed and replaced anyway, but it created a race condition that could have caused spurious notifications or rejected keys if the server responded quickly. As already covered by existing TODOs, a better fix would be to have Start() get out of the business of state migration altogether. But we're approaching a release so I want to make the minimum possible fix. Fixes #1840. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	b7e31ab1a4	ipn: mock controlclient.Client; big ipn.Backend state machine test. A very long unit test that verifies the way the controlclient and ipn.Backend interact. This is a giant sequential test of the state machine. The test passes, but only because it's asserting all the wrong behaviour. I marked all the behaviour I think is wrong with BUG comments, and several additional test opportunities with TODO. Note: the new test supercedes TestStartsInNeedsLoginState, which was checking for incorrect behaviour (although the new test still checks for the same incorrect behaviour) and assumed .Start() would converge before returning, which it happens to do, but only for this very specific case, for the current implementation. You're supposed to wait for the notifications. Updates: tailscale/corp#1660 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Brad Fitzpatrick	53cfff109b	ipn: replace SetWantRunning(bool) with EditPrefs(MaskedPrefs) This adds a new ipn.MaskedPrefs embedding a ipn.Prefs, along with a bunch of "has bits", kept in sync with tests & reflect. Then it adds a Prefs.ApplyEdits(MaskedPrefs) method. Then the ipn.Backend interface loses its weirdo SetWantRunning(bool) method (that I added in `483141094c` for "tailscale down") and replaces it with EditPrefs (alongside the existing SetPrefs for now). Then updates 'tailscale down' to use EditPrefs instead of SetWantRunning. In the future, we can use this to do more interesting things with the CLI, reconfiguring only certain properties without the reset-the-world "tailscale up".
