Val	73e53dcd1c	cmd/tailscale,ipn/ipnlocal: print debug component names ... Make the 'tailscale debug component-logs' command print the component names for which extra logging can be turned on, for easier discoverability of debug functions.

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. The first use case this is for is to be able to tie foreground serve configs to a specific watch session and ensure its clean up when a connection is closed.

Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

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. But keep a test that makes sure that LocalBackend continues to implement it so we get an early warning sign before we break macOS/iOS.

Brad Fitzpatrick	5676d201d6	ipn: add a WatchIPNBus option bit to subscribe to EngineStatus changes ... So GUI clients don't need to poll for it. We still poll internally (for now!) but that's still cheaper. And will get much cheaper later, without having to modify clients once they start sending this bit.

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".

Brad Fitzpatrick	20a357b386	ipn, ipn/ipnserver: add IPN state for server in use, handle explicitly ... On Windows, we were previously treating a server used by different users as a fatal error, which meant the second user (upon starting Tailscale, explicitly or via Start Up programs) got an invasive error message dialog. Instead, give it its own IPN state and change the Notify.ErrMessage to be details in that state. Then the Windows GUI can be less aggresive about that happening. Also, * wait to close the IPN connection until the server ownership state changes so the GUI doesn't need to repeatedly reconnect to discover changes. * fix a bug discovered during testing: on system reboot, the ipnserver's serverModeUser was getting cleared while the state transitioned from Unknown to Running. Instead, track 'inServerMode' explicitly and remove the old accessor method which was error prone. * fix a rare bug where the client could start up and set the server mode prefs in its Start call and we wouldn't persist that to the StateStore storage's prefs start key. (Previously it was only via a prefs toggle at runtime)	4 years ago
Brad Fitzpatrick	515866d7c6	ipn, ipnserver, cmd/tailscale: add "server mode" support on Windows ... This partially (but not yet fully) migrates Windows to tailscaled's StateStore storage system. This adds a new bool Pref, ForceDaemon, defined as: // ForceDaemon specifies whether a platform that normally // operates in "client mode" (that is, requires an active user // logged in with the GUI app running) should keep running after the // GUI ends and/or the user logs out. // // The only current applicable platform is Windows. This // forced Windows to go into "server mode" where Tailscale is // running even with no users logged in. This might also be // used for macOS in the future. This setting has no effect // for Linux/etc, which always operate in daemon mode. Then, when ForceDaemon becomes true, we now write use the StateStore to track which user started it in server mode, and store their prefs under that key. The ipnserver validates the connections/identities and informs that LocalBackend which userid is currently in charge. The GUI can then enable/disable server mode at runtime, without using the CLI. But the "tailscale up" CLI was also fixed, so Windows users can use authkeys or ACL tags, etc. Updates #275	4 years ago

Elias Naur	6e8f0860af	ipn: add Login backend command for sign-in with token ... The StartLoginInteractive command is for delegating the sign-in flow to a browser.

Brad Fitzpatrick	96d806789f	ipn: add Notify.LocalTCPPort field for macOS Network Extension to use ... We want the macOS Network Extension to share fate with the UI frontend, so we need the backend to know when the frontend disappears. One easy way to do that is to reuse the existing TCP server it's already running (for tailscale status clietns). We now tell the frontend our ephemeral TCP port number, and then have the UI connect to it, so the backend can know when it disappears. There are likely Swift ways of doing this, but I couldn't find them quickly enough, so I reached for the hammer I knew.	4 years ago
