Kristoffer Dalby	c4e262a0fc	ipn/profiles: set default prefs based on Windows registry (#6803 ) Co-authored-by: Maisem Ali maisem@tailscale.com	2 years ago
Brad Fitzpatrick	eafbf8886d	ipn/localapi: add localapi debug endpoints for packet filter/matches For debugging #6423. This is easier than TS_DEBUG_MAP, as this means I can pipe things into jq, etc. Updates #6423 Change-Id: Ib3e7496b2eb3f47d4bed42e9b8045a441424b23c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
David Anderson	91e64ca74f	cmd/tailscale/cli: redact private key in debug netmap output by default This makes `tailscale debug watch-ipn` safe to use for troubleshooting user issues, in addition to local debugging during development.

Brad Fitzpatrick	aad6830df0	util/codegen, all: use latest year, not time.Now, in generated files Updates #6865 Change-Id: I6b86c646968ebbd4553cf37df5e5612fbf5c5f7d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Anton Tolchanov	82b9689e25	ipn/ipnlocal: maintain a proxy handler per backend (#6804 ) By default, `http.Transport` keeps idle connections open hoping to re-use them in the future. Combined with a separate transport per request in HTTP proxy this results in idle connection leak. Fixes #6773	2 years ago
Brad Fitzpatrick	0f604923d3	ipn/ipnlocal: fix StatusWithoutPeers not populating parts of Status Fixes #4311 Change-Id: Iaae0615148fa7154f4ef8f66b455e3a6c2fa9df3 Co-authored-by: Claire Wang <claire@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Anton Tolchanov	53c4892841	ipn/ipnserver: propagate http.Serve error This ensures that we capture error returned by `Serve` and exit with a non-zero exit code if it happens. Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago
Joe Tsai	bd2995c14b	ipn/ipnlocal: simplify redactErr (#6716 ) Use multierr.Range to iterate through an error tree instead of multiple invocations of errors.As. This scales better as we add more Go error types to the switch. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Mihai Parparita	47002d93a3	ipn/ipnlocal: add a few metrics for PeerAPI and LocalAPI Mainly motivated by wanting to know how much Taildrop is used, but also useful when tracking down how many invalid requests are generated. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
salman	2d271f3bd1	ipn/ipnlocal: disallow exit nodes from using exit nodes Nodes which have both -advertise-exit-node and -exit-node in prefs should continue have them until the next invocation of `tailscale up`. Updates #3569. Signed-off-by: salman <salman@tailscale.com>	2 years ago
shayne	98114bf608	cmd/tailscale/cli, ipn/localapi: add funnel status to status command (#6402 ) Fixes #6400 open up GETs for localapi serve-config to allow read-only access to ServeConfig `tailscale status` will include "Funnel on" status when Funnel is configured. Prints nothing if Funnel is not running. Example: $ tailscale status <nodes redacted> # Funnel on: # - https://node-name.corp.ts.net # - https://node-name.corp.ts.net:8443 # - tcp://node-name.corp.ts.net:10000 Signed-off-by: Shayne Sweeney <shayne@tailscale.com>	2 years ago

Andrew Dunham	a887ca7efe	ipn/ipnlocal: improve redactErr to handle more cases This handles the case where the inner os.PathError is wrapped in another error type, and additionally will redact errors of type os.LinkError.

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. I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock(). Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Aaron Klotz	659e7837c6	health, ipn/ipnlocal: when -no-logs-no-support is enabled, deny access to tailnets that have network logging enabled We want users to have the freedom to start tailscaled with `-no-logs-no-support`, but that is obviously in direct conflict with tailnets that have network logging enabled. When we detect that condition, we record the issue in health, notify the client, set WantRunning=false, and bail. We clear the item in health when a profile switch occurs, since it is a per-tailnet condition that should not propagate across profiles. Signed-off-by: Aaron Klotz <aaron@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.

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. 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.
