Mihai Parparita	780c56e119	ipn/ipnlocal: add delegated interface information to /interfaces PeerAPI handler ... Exposes the delegated interface data added by #7248 in the debug endpoint. I would have found it useful when working on that PR, and it may be handy in the future as well. Also makes the interfaces table slightly easier to parse by adding borders to it. To make then nicer-looking, the CSP was relaxed to allow inline styles. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago

Mihai Parparita	fa932fefe7	net/interfaces: redo how we get the default interface on macOS and iOS ... With #6566 we added an external mechanism for getting the default interface, and used it on macOS and iOS (see tailscale/corp#8201). The goal was to be able to get the default physical interface even when using an exit node (in which case the routing table would say that the Tailscale utun* interface is the default). However, the external mechanism turns out to be unreliable in some cases, e.g. when multiple cellular interfaces are present/toggled (I have occasionally gotten my phone into a state where it reports the pdp_ip1 interface as the default, even though it can't actually route traffic). It was observed that `ifconfig -v` on macOS reports an "effective interface" for the Tailscale utn* interface, which seems promising. By examining the ifconfig source code, it turns out that this is done via a SIOCGIFDELEGATE ioctl syscall. Though this is a private API, it appears to have been around for a long time (e.g. it's in the 10.13 xnu release at https://opensource.apple.com/source/xnu/xnu-4570.41.2/bsd/net/if_types.h.auto.html) and thus is unlikely to go away. We can thus use this ioctl if the routing table says that a utun* interface is the default, and go back to the simpler mechanism that we had before #6566.

Mihai Parparita	7d204d89c2	ipn/ipnlocal: fix passthrough of formatting arguments in PeerAPI doctor output ... Followup to #7235, we were not treating the formatting arguments as variadic.

Mihai Parparita	6799ef838f	ipn/ipnlocal: add PeerAPI endpoint for doctor output ...

Mihai Parparita	62f4df3257	net/interfaces, net/netns: add node attributes to control default interface getting and binding ... With #6566 we started to more aggressively bind to the default interface on Darwin. We are seeing some reports of the wrong cellular interface being chosen on iOS. To help with the investigation, this adds to knobs to control the behavior changes: - CapabilityDebugDisableAlternateDefaultRouteInterface disables the alternate function that we use to get the default interface on macOS and iOS (implemented in tailscale/corp#8201). We still log what it would have returned so we can see if it gets things wrong. - CapabilityDebugDisableBindConnToInterface is a bigger hammer that disables binding of connections to the default interface altogether.

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>	3 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.

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>	3 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. I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock(). Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago

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>	3 years ago

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	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>	3 years ago

Maisem Ali	235309adc4	all: store NL keys per profile ... This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct. This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey. It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional to be able to delete the "/tka" dir if it exists. This means that we will have a unique key per profile, and a unique directory per profile. Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not delete the ChonkDir. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

Brad Fitzpatrick	3f8e185003	health: add Warnable, move ownership of warnable items to callers ... The health package was turning into a rando dumping ground. Make a new Warnable type instead that callers can request an instance of, and then Set it locally in their code without the health package being aware of all the things that are warnable. (For plenty of things the health package will want to know details of how Tailscale works so it can better prioritize/suppress errors, but lots of the warnings are pretty leaf-y and unrelated) This just moves two of the health warnings.

Aaron Klotz	73b8968404	ipn/ipnlocal: ensure Persist information is saved to server mode start state ... Numerous issues have been filed concerning an inability to install and run Tailscale headlessly in unattended mode, particularly after rebooting. The server mode `Prefs` stored in `server-state.conf` were not being updated with `Persist` state once the node had been succesfully logged in. Users have been working around this by finagling with the GUI to make it force a state rewrite. This patch makes that unnecessary by ensuring the required server mode state is updated when prefs are updated by the control client.

One of the methods needed nothing from its receiver. This will make a future change easier to reason about.

Brad Fitzpatrick	65c24b6334	envknob: generalize Windows tailscaled-env.txt support ... ipnserver previously had support for a Windows-only environment variable mechanism that further only worked when Windows was running as a service, not from a console. But we want it to work from tailscaed too, and we want it to work on macOS and Synology. So move it to envknob, now that envknob can change values at runtime post-init. A future change will wire this up for more platforms, and do something more for CLI flags like --port, which the bug was originally about.

Brad Fitzpatrick	4a82b317b7	ipn/{ipnlocal,localapi}: use strs.CutPrefix, add more domain validation ... The GitHub CodeQL scanner flagged the localapi's cert domain usage as a problem because user input in the URL made it to disk stat checks. The domain is validated against the ipnstate.Status later, and only authenticated root/configured users can hit this, but add some paranoia anyway.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support ... As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

Tom DNetto	79905a1162	tka: make storage a parameter rather than an Authority struct member ... Updates #5435 Based on the discussion in #5435, we can better support transactional data models by making the underlying storage layer a parameter (which can be specialized for the request) rather than a long-lived member of Authority. Now that Authority is just an instantaneous snapshot of state, we can do things like provide idempotent methods and make it cloneable, too. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
