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	055394f3be	ipn/ipnlocal: add mutex to webClient struct Adds a new sync.Mutex field to the webClient struct, rather than using the general LocalBackend mutex. Since webClientGetOrInit (previously WebClientInit) gets called on every connection, we want to avoid holding the lock on LocalBackend just to check if the server is initialized. Moves all web_client.go funcs over to using the webClient.mu field. Updates tailscale/corp#14335 Signed-off-by: Sonia Appasamy <sonia@tailscale.com>	12 months ago
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.

Joe Tsai	975c5f7684	taildrop: lazily perform full deletion scan after first taildrop use (#10137 ) Simply reading the taildrop directory can pop up security dialogs on platforms like macOS. Avoid this by only performing garbage collection of partial and deleted files after the first received taildrop file, which would have prompted the security dialog window.

Will Norris	09de240934	ipn/ipnlocal: allow connecting to local web client The local web client has the same characteristic as tailscale serve, in that it needs a local listener to allow for connections from the local machine itself when running in kernel networking mode.

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.

Will Norris	6b956b49e0	client/web: add some security checks for full client Require that requests to servers in manage mode are made to the Tailscale IP (either ipv4 or ipv6) or quad-100. Also set various security headers on those responses. These might be too restrictive, but we can relax them as needed. Allow requests to /ok (even in manage mode) with no checks. This will be used for the connectivity check from a login client to see if the management client is reachable. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Will Norris	658971d7c0	ipn/ipnlocal: serve web client on quad100 if enabled if the user pref and nodecap for the new web client are enabled, serve the client over requests to 100.100.100.100. 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). That is something we'll fix in a subsequent PR in the web client code itself. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago

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	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.
