Andrew Lytvynov	77127a2494	clientupdate: fix background install for linux tarballs (#9852) ... Two bug fixes: 1. when tailscale update is executed as root, `os.UserCacheDir` may return an error because `$XDG_CACHE_HOME` and `$HOME` are not set; fallback to `os.TempDir` in those cases 2. on some weird distros (like my EndeavourOS), `/usr/sbin` is just a symlink to `/usr/bin`; when we resolve `tailscale` binary path from `tailscaled`, allow `tailscaled` to be in either directory Updates #755 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	1 year ago
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.

Maisem Ali	24f322bc43	ipn/ipnlocal: do unexpired cert renewals in the background ... We were eagerly doing a synchronous renewal of the cert while trying to serve traffic. Instead of that, just do the cert renewal in the background and continue serving traffic as long as the cert is still valid. This regressed in c1ecae13ab when we introduced ARI support and were trying to make the experience of `tailscale cert` better. However, that ended up regressing the experience for tsnet as it would not always doing the renewal synchronously. Fixes #9783 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago

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.

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.

This fix does not seem ideal, but the test infrastructure using a local goos doesn't seem to avoid all of the associated challenges, but is somewhat deeply tied to the setup. The core issue this addresses for now is that when run on Windows there can be no code paths that attempt to use an invalid UID string, which on Windows is described in [1]. For the goos="linux" tests, we now explicitly skip the affected migration code if runtime.GOOS=="windows", and for the Windows test we explicitly use the running users uid, rather than just the string "user1". We also now make the case where a profile exists and has already been migrated a non-error condition toward the outer API.

Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled ... I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.

shayne	7908b6d616	ipn/ipnlocal: [serve] Trim mountPoint prefix from proxy path (#7334) ... This change trims the mountPoint from the request URL path before sending the request to the reverse proxy. Today if you mount a proxy at `/foo` and request to `/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request URL's path. This fix makes removed the `mountPoint` prefix from the path so proxied services receive requests as if they were running at the root (`/`) path. This could be an issue if the app generates URLs (in HTML or otherwise) and assumes `/path`. In this case, those URLs will 404. With that, I still think we should trim by default and not leak the `mountPoint` (specific to Tailscale) into whatever app is hosted. If it causes an issue with URL generation, I'd suggest looking at configuring an app-specific path prefix or running Caddy as a more advanced solution.

Mihai Parparita	97b6d3e917	sockstats: remove per-interface stats from Get ...

If changing sockstatlog to sample at 10,000 Hz (instead of the default of 10Hz), the CPU usage would go up to 59% on a iPhone XS.

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.
