Brad Fitzpatrick	55bb7314f2	control/controlclient: replace a status func with Observer interface For now the method has only one interface (the same as the func it's replacing) but it will grow, eventually with the goal to remove the controlclient.Status type for most purposes.

Brad Fitzpatrick	ea4425d8a9	ipn/ipnlocal, wgengine/magicsock: move UpdateStatus stuff around Upcoming work on incremental netmap change handling will require some replumbing of which subsystems get notified about what. Done naively, it could break "tailscale status --json" visibility later. To make sure I understood the flow of all the updates I was rereading the status code and realized parts of ipnstate.Status were being populated by the wrong subsystems. The engine (wireguard) and magicsock (data plane, NAT traveral) should only populate the stuff that they uniquely know. The WireGuard bits were fine but magicsock was populating stuff stuff that LocalBackend could've better handled, so move it there.

Brad Fitzpatrick	4511e7d64e	ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User In `b987b2ab18` (2021-01-12) when we introduced sharing we mapped the sharer to the userid at a low layer, mostly to fix the display of "tailscale status" and the client UIs, but also some tests. The commit earlier today, `7dec09d169`, removed the 2.5yo option to let clients disable that automatic mapping, as clearly we were never getting around to it. This plumbs the Sharer UserID all the way to ipnstatus so the CLI itself can choose to print out the Sharer's identity over the node's original owner. Then we stop mangling Node.User and let clients decide how they want to render things. To ease the migration for the Windows GUI (which currently operates on tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus), a new method Node.SharerOrUser is added to do the mapping of Sharer-else-User.

Charlotte Brandhorst-Satzkorn	35bdbeda9f	cli: introduce exit-node subcommand to list and filter exit nodes This change introduces a new subcommand, `exit-node`, along with a subsubcommand of `list` and a `--filter` flag. Exit nodes without location data will continue to be displayed when `status` is used. Exit nodes with location data will only be displayed behind `exit-node list`, and in status if they are the active exit node. The `filter` flag can be used to filter exit nodes with location data by country. Exit nodes with Location.Priority data will have only the highest priority option for each country and city listed. For countries with multiple cities, a <Country> <Any> option will be displayed, indicating the highest priority node within that country.

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail).

Maisem Ali	b797f773c7	ipn/ipnlocal: add support for funnel in tsnet Previously the part that handled Funnel connections was not aware of any listeners that tsnet.Servers might have had open so it would check against the ServeConfig and fail. Adding a ServeConfig for a TCP proxy was also not suitable in this scenario as that would mean creating two different listeners and have one forward to the other, which really meant that you could not have funnel and tailnet-only listeners on the same port. This also introduces the ipn.FunnelConn as a way for users to identify whether the call is coming over funnel or not. Currently it only holds the underlying conn and the target as presented in the "Tailscale-Ingress-Target" header. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 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	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.

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

Andrew Dunham	2703d6916f	net/netns: add functionality to bind outgoing sockets based on route table When turned on via environment variable (off by default), this will use the BSD routing APIs to query what interface index a socket should be bound to, rather than binding to the default interface in all cases.

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
Andrew Dunham	3a018e51bb	ipn/ipnlocal: move handling of expired nodes to LocalBackend In order to be able to synthesize a new NetMap when a node expires, have LocalBackend start a timer when receiving a new NetMap that fires slightly after the next node expires. Additionally, move the logic that updates expired nodes into LocalBackend so it runs on every netmap (whether received from controlclient or self-triggered).

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
