Anton Tolchanov	8cc5c51888	health: warn about reverse path filtering and exit nodes When reverse path filtering is in strict mode on Linux, using an exit node blocks all network connectivity. This change adds a warning about this to `tailscale status` and the logs. Example in `tailscale status`: ``` - not connected to home DERP region 22 - The following issues on your machine will likely make usage of exit nodes impossible: [interface "eth0" has strict reverse-path filtering enabled], please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310 ``` Example in the logs: ``` 2024/02/21 21:17:07 health("overall"): error: multiple errors: not in map poll The following issues on your machine will likely make usage of exit nodes impossible: [interface "eth0" has strict reverse-path filtering enabled], please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310 ``` Updates #3310 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago

Will Norris	128c99d4ae	client/web: add new readonly mode The new read-only mode is only accessible when running `tailscale web` by passing a new `-readonly` flag. This new mode is identical to the existing login mode with two exceptions: - the management client in tailscaled is not started (though if it is already running, it is left alone) - the client does not prompt the user to login or switch to the management client. Instead, a message is shown instructing the user to use other means to manage the device. Updates #10979 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Andrew Dunham	727acf96a6	net/netcheck: use DERP frames as a signal for home region liveness This uses the fact that we've received a frame from a given DERP region within a certain time as a signal that the region is stil present (and thus can still be a node's PreferredDERP / home region) even if we don't get a STUN response from that region during a netcheck.

Andrew Lytvynov	d8493d4bd5	clientupdate: add explicit Track to Arguments (#10548 ) Instead of overloading the Version field, add an explicit Track field.

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.

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.

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. This means that all 1.55 unstable builds, and then eventually the 1.56 build, will work without setting the node capability. The web client still requires the "webclient" user pref, so this does NOT mean that the web client will be on by default for all devices.
