Will Norris	3e9026efda	client/web: show manage button in readonly view ... We render the readonly view in two situations: - the client is in login mode, and the device is connected - the client is in manage mode, but the user does not yet have a session If the user is not authenticated, and they are not currently on the Tailscale IP address, render a "Manage" button that will take them to the Tailcale IP of the device and immediately start check mode. Still to do is detecting if they have connectivity to the Tailscale IP, and disabling the button if not. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Sonia Appasamy	3269b36bd0	client/web: fix hotreload proxy ... Previously had HMR websocket set to run from a different port than the http proxy server. This was an old setting carried over from the corp repo admin panel config. It's messing with hot reloads when run from the tailscaled web client, as it keeps causing the full page to refresh each time a connection is made. Switching back to the default config here fixes things. Updates tailscale/corp#14335 Signed-off-by: Sonia Appasamy <sonia@tailscale.com>	1 year ago

Will Norris	e537d304ef	client/web: relax CSP restrictions for manage client ... Don't return CSP headers in dev mode, since that includes a bunch of extra things like the vite server. Allow images from any source, which is needed to load user profile images. Allow 'unsafe-inline' for various inline scripts and style react uses. We can eliminate this by using CSP nonce or hash values, but we'll need to look into the best way to handle that. There appear to be several react plugins for this, but I haven't evaluated any of them. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Will Norris	a05ab9f3bc	client/web: check r.Host rather than r.URL.Host ... r.URL.Host is not typically populated on server requests. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
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
Sonia Appasamy	e5dcf7bdde	client/web: move auth session creation out of /api/auth ... Splits auth session creation into two new endpoints: /api/auth/session/new - to request a new auth session /api/auth/session/wait - to block until user has completed auth url Updates tailscale/corp#14335 Signed-off-by: Sonia Appasamy <sonia@tailscale.com>	1 year ago

Sonia Appasamy	191e2ce719	client/web: add ServerMode to web.Server ... Adds a new Mode to the web server, indicating the specific scenario the constructed server is intended to be run in. Also starts filling this from the cli/web and ipn/ipnlocal callers. From cli/web this gets filled conditionally based on whether the preview web client node cap is set. If not set, the existing "legacy" client is served. If set, both a login/lobby and full management client are started (in "login" and "manage" modes respectively).

Will Norris	4ce4bb6271	client/web: limit authorization checks to API calls ... This completes the migration to setting up authentication state in the client first before fetching any node data or rendering the client view. Notable changes: - `authorizeRequest` is now only enforced on `/api/*` calls (with the exception of /api/auth, which is handled early because it's needed to initially setup auth, particularly for synology) - re-separate the App and WebClient components to ensure that auth is completed before moving on - refactor platform auth (synology and QNAP) to fit into this new structure. Synology no longer returns redirect for auth, but returns authResponse instructing the client to fetch a SynoToken Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago

Will Norris	e5fbe57908	web/client: update synology token from /api/auth call ...

Sonia Appasamy	6f214dec48	client/web: split out UI components ... This commit makes the following structural changes to the web client interface. No user-visible changes. 1. Splits login, legacy, readonly, and full management clients into their own components, and pulls them out into their own view files. 2. Renders the same Login component for all scenarios when the client is not logged in, regardless of legacy or debug mode. Styling comes from the existing legacy login, which is removed from legacy.tsx now that it is shared. 3. Adds a ui folder to hold non-Tailscale-specific components, starting with ProfilePic, previously housed in app.tsx.

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.

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.

Sonia Appasamy	1df2d14c8f	client/web: use auth ID in browser sessions ... Stores ID from tailcfg.WebClientAuthResponse in browser session data, and uses ID to hit control server /wait endpoint.

Will Norris	9a3bc9049c	client/web,cmd/tailscale: add prefix flag for web command ... We already had a path on the web client server struct, but hadn't plumbed it through to the CLI. Add that now and use it for Synology and QNAP instead of hard-coding the path. (Adding flag for QNAP is tailscale/tailscale-qpkg#112) This will allow supporting other environments (like unraid) without additional changes to the client/web package. Also fix a small bug in unraid handling to only include the csrf token on POST requests. Updates tailscale/corp#13775 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Will Norris	37eab31f68	client/web: simply csrf key caching in cgi mode ... Instead of trying to use the user config dir, and then fail back to the OS temp dir, just always use the temp dir. Also use a filename that is less likely to cause collisions. This addresses an issue on a test synology instance that was mysteriously failing because there was a file at /tmp/tailscale. We could still technically run into this issue if a /tmp/tailscale-web-csrf.key file exists, but that seems far less likely.

Will Norris	d74c771fda	client/web: always use new web client; remove old client ... This uses the new react-based web client for all builds, not just with the --dev flag. If the web client assets have not been built, the client will serve a message that Tailscale was built without the web client, and link to build instructions. Because we will include the web client in all of our builds, this should only be seen by developers or users building from source. (And eventually this will be replaced by attempting to download needed assets as runtime.) We do now checkin the build/index.html file, which serves the error message when assets are unavailable. This will also eventually be used to trigger in CI when new assets should be built and uploaded to a well-known location.

Sonia Appasamy	f3077c6ab5	client/web: add self node cache ... Adds a cached self node to the web client Server struct, which will be used from the web client api to verify that request came from the node's own machine (i.e. came from the web client frontend). We'll be using when we switch the web client api over to acting as a proxy to the localapi, to protect against DNS rebinding attacks.

Will Norris	dc8287ab3b	client/web: enforce full path for CGI platforms ... Synology and QNAP both run the web client as a CGI script. The old web client didn't care too much about requests paths, since there was only a single GET and POST handler. The new client serves assets on different paths, so now we need to care. First, enforce that the CGI script is always accessed from its full path, including a trailing slash (e.g. /cgi-bin/tailscale/index.cgi/). Then, strip that prefix off before passing the request along to the main serve handler. This allows for properly serving both static files and the API handler in a CGI environment. Also add a CGIPath option to allow other CGI environments to specify a custom path. Finally, update vite and one "api/data" call to no longer assume that we are always serving at the root path of "/".

Will Norris	0c3d343ea3	client/web: invert auth logic for synology and qnap ... Add separate server methods for synology and qnap, and enforce authentication and authorization checks before calling into the actual serving handlers. This allows us to remove all of the auth logic from those handlers, since all requests will already be authenticated by that point. Also simplify the Synology token redirect handler by using fetch. Remove the SynologyUser from nodeData, since it was never used in the frontend anyway. Updates tailscale/corp#13775 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago

Will Norris	9ea3942b1a	client/web: don't require secure cookies for csrf ... Under normal circumstances, you would typically want to keep the default behavior of requiring secure cookies. In the case of the Tailscale web client, we are regularly serving on localhost (where secure cookies don't really matter), and/or we are behind a reverse proxy running on a network appliance like a NAS or Home Assistant. In those cases, those devices are regularly accessed over local IP addresses without https configured, so would not work with secure cookies.

But it turns out this was part of the original web client added in #1621, and then refactored as part of #2093. But with how we handle logging in now, it's never called.

Will Norris	0df5507c81	client/web: combine embeds into a single embed.FS ... instead of embedding each file individually, embed them all into a single embed filesystem. This is basically a noop for the current frontend, but sets things up a little cleaner for the new frontend. Also added an embed.FS for the source files needed to build the new frontend. These files are not actually embedded into the binary (since it is a blank identifier), but causes `go mod vendor` to copy them into the vendor directory.
