Maisem Ali	17b2072b72	ipn/ipnlocal: set the push device token correctly It would end up resetting whatever hostinfo we had constructed and leave the backend statemachine in a broken state. This fixes that by storing the PushDeviceToken on the LocalBackend and populating it on Hostinfo before passing it to controlclient.

Joe Tsai	c2a551469c	taildrop: implement asynchronous file deletion (#9844 ) File resumption requires keeping partial files around for some time, but we must still eventually delete them if never resumed. Thus, we implement asynchronous file deletion, which could spawn a background goroutine to delete the files. We also use the same mechanism for deleting files on Windows, where a file can't be deleted if there is still an open file handle. We can enqueue those with the asynchronous file deleter as well.

Joe Tsai	b1867eb23f	taildrop: add logic for resuming partial files (#9785 ) We add the following API: * type FileChecksums * type Checksum * func Manager.PartialFiles * func Manager.HashPartialFile * func ResumeReader The Manager methods provide the ability to query for partial files and retrieve a list of checksums for a given partial file. The ResumeReader function is a helper that wraps an io.Reader to discard content that is identical locally and remotely. The FileChecksums type represents the checksums of a file and is safe to JSON marshal and send over the wire.

James Tucker	c7ce4e07e5	ipn/ipnlocal: allow Split-DNS and default resolvers with WireGuard nodes The initial implementation directly mirrored the behavior of Tailscale exit nodes, where the WireGuard exit node DNS took precedence over other configuration. This adjusted implementation treats the WireGuard DNS resolvers as a lower precedence default resolver than the tailnet default resolver, and allows split DNS configuration as well. This also adds test coverage to the existing DNS selection behavior with respect to default resolvers and split DNS routes for Tailscale exit nodes above cap 25. There may be some refinement to do in the logic in those cases, as split DNS may not be working as we intend, though that would be a pre-existing and separate issue.

Brad Fitzpatrick	9538e9f970	ipn/ipnlocal: keep internal map updated of latest Nodes post mutations We have some flaky integration tests elsewhere that have no one place to ask about the state of the world. This makes LocalBackend be that place (as it's basically there anyway) but doesn't yet add the ForTest accessor method. This adds a LocalBackend.peers map[NodeID]NodeView that is incrementally updated as mutations arrive. And then we start moving away from using NetMap.Peers at runtime (UpdateStatus no longer uses it now). And remove another copy of NodeView in the LocalBackend nodeByAddr map. Change that to point into b.peers instead. Future changes will then start streaming whole-node-granularity peer change updates to WatchIPNBus clients, tracking statefully per client what each has seen. This will get the GUI clients from receiving less of a JSON storm of updates all the time.

Maisem Ali	959362a1f4	ipn/ipnlocal,control/controlclient: make Logout more sync We already removed the async API, make it more sync and remove the FinishLogout state too.

Maisem Ali	7074a40c06	control/controlclient: run SetControlClientStatus in goroutine We have cases where the SetControlClientStatus would result in a Shutdown call back into the auto client that would block forever. The right thing to do here is to fix the LocalBackend state machine but thats a different dumpster fire that we are slowly making progress towards. This makes it so that the SetControlClientStatus happens in a different goroutine so that calls back into the auto client do not block. Also add a few missing mu.Unlocks in LocalBackend.Start.

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.
