Andrew Dunham	cab2b2b59e	ipn/localapi: print envknobs on bugreport Previously, we only printed these at startup; print those when the user generates a bugreport as we so we don't have to go spelunking through the logs.

Maisem Ali	0fd2f71a1e	ipn/ipnlocal: use presence of NodeID to identify logins The profileManager was using the LoginName as a proxy to figure out if the profile had logged in, however the LoginName is not present if the node was created with an Auth Key that does not have an associated user.

Andrew Dunham	6d84f3409b	ipn/ipnlocal: handle more edge cases in netmap expiry timer We now handle the case where the NetworkMap.SelfNode has already expired and do not return an expiry time in the past (which causes an ~infinite loop of timers to fire). Additionally, we now add an explicit check to ensure that the next expiry time is never before the current local-to-the-system time, to ensure that we don't end up in a similar situation due to clock skew. Finally, we add more tests for this logic to ensure that we don't regress on these edge cases.

Mihai Parparita	4973956419	ipn/ipnlocal: add /reset-auth LocalAPI endpoint The iOS has a command to reset the persisted state of the app, but it was doing its own direct keychain manipulation. This proved to be brittle (since we changed how preferences are stored with #6022), so we instead add a LocalAPI endpoint to do do this, which can be updated in tandem. This clears the same state as the iOS implementation (tailscale/corp#3186), that is the machine key and preferences (which includes the node key). Notably this does not clear the logtail ID, so that logs from the device still end up in the same place. Updates tailscale/corp#8923 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

shayne	4471e403aa	ipn/ipnlocal: [serve] listen on all-interfaces for macOS sandboxed (#6771 ) On macOS (AppStore and macsys), we need to bind to ""/all-interfaces due to the network sandbox. Ideally we would only bind to the Tailscale interface, but macOS errors out if we try to to listen on privileged ports binding only to a specific interface. We also implement the lc.Control hook, same as we do for peerapi. It doesn't solve our problem but it's better that we do and would likely be required when Apple gets around to fixing per-interface priviliged port binding.

salman	eec734a578	ipn/{ipnlocal,localapi}: ensure watcher is installed before /watch-ipn-bus/ responds with 200 This change delays the first flush in the /watch-ipn-bus/ handler until after the watcher has been successfully installed on the IPN bus. It does this by adding a new onWatchAdded callback to LocalBackend.WatchNotifications(). Without this, the endpoint returns a 200 almost immediatly, and only then installs a watcher for IPN events. This means there's a small window where events could be missed by clients after calling WatchIPNBus(). Fixes tailscale/corp#8594. Signed-off-by: salman <salman@tailscale.com>	2 years ago

Tom DNetto	f1ab11e961	ipn/ipnlocal,tailcfg: introduce capability to gate TKA init paths Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With this change: - Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded) require either the WIP envknob or CapabilityTailnetLockAlpha. - Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the envknob / capability. - Auxillary commands (ie: changing tka keys) require TKA to be initialized. The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being sent the capability or setting the envknob on tailscaled yourself.

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.

Aaron Klotz	6e33d2da2b	ipn/ipnauth, util/winutil: add temporary LookupPseudoUser workaround to address os/user.LookupId errors on Windows I added util/winutil/LookupPseudoUser, which essentially consists of the bits that I am in the process of adding to Go's standard library. We check the provided SID for "S-1-5-x" where 17 <= x <= 20 (which are the known pseudo-users) and then manually populate a os/user.User struct with the correct information.

Brad Fitzpatrick	3b0de97e07	cmd/tailscaled: unify the two Windows paths + separate IPN server path tailscaled on Windows had two entirely separate start-up paths for running as a service vs in the foreground. It's been causing problems for ages. This unifies the two paths, making them be the same as the path used for every other platform. Also, it uses the new async LocalBackend support in ipnserver.Server so the Server can start serving HTTP immediately, even if tun takes awhile to come up.

Brad Fitzpatrick	ea25ef8236	util/set: add new set package for SetHandle type We use this pattern in a number of places (in this repo and elsewhere) and I was about to add a fourth to this repo which was crossing the line. Add this type instead so they're all the same. Also, we have another Set type (SliceSet, which tracks its keys in order) in another repo we can move to this package later.

Brad Fitzpatrick	e8cc78b1af	ipn/ipnserver: change Server to let LocalBackend be supplied async This is step 1 of de-special-casing of Windows and letting the LocalAPI HTTP server start serving immediately, even while the rest of the world (notably the Engine and its TUN device) are being created, which can take a few to dozens of seconds on Windows. With this change, the ipnserver.New function changes to not take an Engine and to return immediately, not returning an error, and let its Run run immediately. If its ServeHTTP is called when it doesn't yet have a LocalBackend, it returns an error. A TODO in there shows where a future handler will serve status before an engine is available. Future changes will: * delete a bunch of tailscaled_windows.go code and use this new API * add the ipnserver.Server ServerHTTP handler to await the engine being available * use that handler in the Windows GUI client Updates #6522 Change-Id: Iae94e68c235e850b112a72ea24ad0e0959b568ee Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	8049053f86	ipn/*: make new WindowsUserID type to consolidate docs The "userID is empty everywhere but Windows" docs on lots of places but not everywhere while using just a string type was getting confusing.

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

With this ipn.BackendServer is no longer used and could also be removed from this repo.
