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 Useful when debugging issues (e.g. to see the full routing table), and easier to refer to the output via a browser than trying to read it from the logs generated by `bugreport --diagnose`.

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>	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
