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	1a4d423328	ipn/ipnlocal: add additional syspolicy enforcement This adds support for enforcing exit node LAN access, DNS and subnet routes. Adding new preference policies was getting repetitive, so this turns some of the boilerplate into a table.

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. This change ensures that policies are applied whenever preferences are loaded or changed, so a CLI or GUI client that does not respect the policies will still be overridden. Exit node IP is dropped from this PR as it was implemented elsewhere in #10172.

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.

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>	1 year ago

Tom DNetto	3496d62ed3	ipn/ipnlocal: add empty address to the app-connector localNets set App connectors handle DNS requests for app domains over PeerAPI, but a safety check verifies the requesting peer has at least permission to send traffic to 0.0.0.0:53 (or 2000:: for IPv6) before handling the DNS request. The correct filter rules are synthesized by the coordination server and sent down, but the address needs to be part of the 'local net' for the filter package to even bother checking the filter rules, so we set them here.

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.

For now, this will render the readonly full management client, with an "access" button that sends the user through 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.

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.

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.

Tom DNetto	c08cf2a9c6	all: declare & plumb IPv6 masquerade address for peer This PR plumbs through awareness of an IPv6 SNAT/masquerade address from the wire protocol through to the low-level (tstun / wgengine). This PR is the first in two PRs for implementing IPv6 NAT support to/from peers. A subsequent PR will implement the data-plane changes to implement IPv6 NAT - this is just plumbing.

Maisem Ali	19a9d9037f	tailcfg: add NodeCapMap Like PeerCapMap, add a field to `tailcfg.Node` which provides a map of Capability to raw JSON messages which are deferred to be parsed later by the application code which cares about the specific capabilities. This effectively allows us to prototype new behavior without having to commit to a schema in tailcfg, and it also opens up the possibilities to develop custom behavior in tsnet applications w/o having to plumb through application specific data in the MapResponse.

Brad Fitzpatrick	0d991249e1	types/netmap: remove NetworkMap.{Addresses,MachineStatus} And convert all callers over to the methods that check SelfNode. Now we don't have multiple ways to express things in tests (setting fields on SelfNode vs NetworkMap, sometimes inconsistently) and don't have multiple ways to check those two fields (often only checking one or the other).

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.
