Adrian Dewhurst	c05c4bdce4	ipn: apply ControlURL policy before login Unlike most prefs, the ControlURL policy needs to take effect before login. This resolves an issue where on first start, even when the ControlURL policy is set, it will generate a login URL to the Tailscale SaaS server.

Andrew Dunham	d3574a350f	cmd/tailscale, ipn/ipnlocal: add 'debug dial-types' command This command allows observing whether a given dialer ("SystemDial", "UserDial", etc.) will successfully obtain a connection to a provided host, from inside tailscaled itself. This is intended to help debug a variety of issues from subnet routers to split DNS setups.

Adrian Dewhurst	86aa0485a6	ipn/ipnlocal, util/syspolicy: make run exit node a preference option Previously, the "RunExitNode" policy merely controlled the visibility of the "run as exit node" menu item, not the setting itself. This migrates that setting to a preference option named "AdvertiseExitNode".

Andrew Lytvynov	e25f114916	ipn,cmd/tailscale/cli: support hierarchical MaskedPrefs (#10507 ) Some fields if `ipn.Prefs` are structs. `ipn.MaskedPrefs` has a single level of boolean `*Set` flags, which doesn't map well to nested structs within `ipn.Prefs`. Change `MaskedPrefs` and `ApplyEdits` to support `FooSet` struct fields that map to a nested struct of `ipn.Prefs` like `AutoUpdates`. Each struct field in `MaskedPrefs` is just a bundle of more `Set` bool fields or other structs. This allows you to have a `Set` flag for any arbitrarily-nested field of `ipn.Prefs`. Also, make `ApplyEdits` match fields between `Prefs` and `MaskedPrefs` by name instead of order, to make it a bit less finicky. It's probably slower but `ipn.ApplyEdits` should not be in any hot path. As a result, `AutoUpdate.Check` and `AutoUpdate.Apply` fields don't clobber each other when set individually.

Adrian Dewhurst	f706a3abd0	ipn/ipnlocal, util/syspolicy: add auto update policy Due to the Sparkle preference naming convention, macsys already has a policy key named "ApplyUpdates" that merely shows or hides the menu item that controls if auto updates are installed, rather than directly controlling the setting. For other platforms, we are going to use "InstallUpdates" instead because it seemed better than the other options that were considered.

Adrian Dewhurst	af32d1c120	ipn/ipnlocal: better enforce system policies Previously, policies affected the default prefs for a new profile, but that does not affect existing profiles.

Marwan Sulaiman	2dc0645368	ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profile This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled clients can use this value to disambiguate fast user switching from one tailnet to another that are under the same exact login. We will also try to backfill this information during backend starts and profile switches so that users don't have to re-authenticate their profile. The first client to use this new information is the CLI in 'tailscale switch -list' which now uses text/tabwriter to display the ID, Tailnet, and Account. Since account names are ambiguous, we allow the user to pass 'tailscale switch ID' to specify the exact tailnet they want to switch to.

Sonia Appasamy	bd534b971a	{client/web},{ipn/ipnlocal}: replace localapi debug-web-client endpoint This change removes the existing debug-web-client localapi endpoint and replaces it with functions passed directly to the web.ServerOpts when constructing a web.ManageServerMode client. The debug-web-client endpoint previously handled making noise requests to the control server via the /machine/webclient/ endpoints. The noise requests must be made from tailscaled, which has the noise connection open. But, now that the full client is served from tailscaled, we no longer need to proxy this request over the localapi.

Will Norris	9b537f7c97	ipn: remove the preview-webclient node capability Now that 1.54 has released, and the new web client will be included in 1.56, we can remove the need for the node capability.

Andrew Lytvynov	955e2fcbfb	ipn/ipnlocal: run "tailscale update" via systemd-run on Linux (#10229 ) When we run tailscled under systemd, restarting the unit kills all child processes, including "tailscale update". And during update, the package manager will restart the tailscaled unit. Specifically on Debian-based distros, interrupting `apt-get install` can get the system into a wedged state which requires the user to manually run `dpkg --configure` to recover. To avoid all this, use `systemd-run` where available to run the `tailscale update` process. This launches it in a separate temporary unit and doesn't kill it when parent unit is restarted. Also, detect when `apt-get install` complains about aborted update and try to restore the system by running `dpkg --configure tailscale`. This could help if the system unexpectedly shuts down during our auto-update. Fixes https://github.com/tailscale/corp/issues/15771 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	8 months ago

Aaron Klotz	fbc18410ad	ipn/ipnauth: improve the Windows token administrator check (Token).IsAdministrator is supposed to return true even when the user is running with a UAC limited token. The idea is that, for the purposes of this check, we don't care whether the user is currently* running with full Admin rights, we just want to know whether the user can potentially do so. We accomplish this by querying for the token's "linked token," which should be the fully-elevated variant, and checking its group memberships. We also switch ipn/ipnserver/(*Server).connIsLocalAdmin to use the elevation check to preserve those semantics for tailscale serve; I want the IsAdministrator check to be used for less sensitive things like toggling auto-update on and off.

Today, that is just a static page that lists the local Tailcale IP addresses. For now, this will render the readonly full management client, with an "access" button that sends the user through check mode. After completing check mode, they will still be in the read-only view, since they are not accessing the client over Tailscale. Instead, quad100 should serve the lobby client that has a "manage" button that will open the management client on the Tailscale IP (and trigger check mode).

Sonia Appasamy	89953b015b	ipn/ipnlocal,client/web: add web client to tailscaled Allows for serving the web interface from tailscaled, with the ability to start and stop the server via localapi endpoints (/web/start and /web/stop). This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.

Aaron Klotz	95671b71a6	ipn, safesocket: use Windows token in LocalAPI On Windows, the idiomatic way to check access on a named pipe is for the server to impersonate the client on its current OS thread, perform access checks using the client's access token, and then revert the OS thread's access token back to its true self. The access token is a better representation of the client's rights than just a username/userid check, as it represents the client's effective rights at connection time, which might differ from their normal rights. This patch updates safesocket to do the aforementioned impersonation, extract the token handle, and then revert the impersonation. We retain the token handle for the remaining duration of the connection (the token continues to be valid even after we have reverted back to self). Since the token is a property of the connection, I changed ipnauth to wrap the concrete net.Conn to include the token. I then plumbed that change through ipnlocal, ipnserver, and localapi as necessary. I also added a PermitLocalAdmin flag to the localapi Handler which I intend to use for controlling access to a few new localapi endpoints intended for configuring auto-update.

Sonia Appasamy	68da15516f	ipn/localapi,client/web: clean up auth error handling This commit makes two changes to the web client auth flow error handling: 1. Properly passes back the error code from the noise request from the localapi. Previously we were using io.Copy, which was always setting a 200 response status code. 2. Clean up web client browser sessions on any /wait endpoint error. This avoids the user getting in a stuck state if something goes wrong with their auth path.

Joe Tsai	3f27087e9d	taildrop: switch hashing to be streaming based (#9861 ) While the previous logic was correct, it did not perform well. Resuming is a dance between the client and server, where 1. the client requests hashes for a partial file, 2. the server then computes those hashes, 3. the client computes hashes locally and compares them. 4. goto 1 while the partial file still has data While step 2 is running, the client is sitting idle. While step 3 is running, the server is sitting idle. By streaming over the block hash immediately after the server computes it, the client can start checking the hash, while the server works on the next hash (in a pipelined manner). This performs dramatically better and also uses less memory as we don't need to hold a list of hashes, but only need to handle one hash at a time. There are two detriments to this approach: * The HTTP API relies on a JSON stream, which is not a standard REST-like pattern. However, since we implement both client and server, this is fine. * While the stream is on-going, we hold an open file handle on the server side while the file is being hashed. On really slow streams, this could hold a file open forever.

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.
