Aaron Klotz	855f79fad7	cmd/tailscaled, util/winutil: changes to process and token APIs in winutil ... This PR changes the internal getTokenInfo function to use generics. I also removed our own implementations for obtaining a token's user and primary group in favour of calling the ones now available in x/sys/windows. Furthermore, I added two new functions for working with tokens, logon session IDs, and Terminal Services / RDP session IDs. I modified our privilege enabling code to allow enabling of multiple privileges via one single function call. Finally, I added the ProcessImageName function and updated the code in tailscaled_windows.go to use that instead of directly calling the underlying API. All of these changes will be utilized by subsequent PRs pertaining to this issue. Updates https://github.com/tailscale/corp/issues/13998 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	8 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.

Aaron Klotz	47019ce1f1	cmd/tailscaled: pre-load wintun.dll using a fully-qualified path ... In corp PR #14970 I updated the installer to set a security mitigation that always forces system32 to the front of the Windows dynamic linker's search path. Unfortunately there are other products out there that, partying like it's 1995, drop their own, older version of wintun.dll into system32. Since we look there first, we end up loading that old version. We can fix this by preloading wintun using a fully-qualified path. When wintun-go then loads wintun, the dynamic linker will hand it the module that was previously loaded by us.

Brad Fitzpatrick	3d7fb6c21d	derp/derphttp: fix race in mesh watcher ... The derphttp client automatically reconnects upon failure. RunWatchConnectionLoop called derphttp.Client.WatchConnectionChanges once, but that wrapper method called the underlying derp.Client.WatchConnectionChanges exactly once on derphttp.Client's currently active connection. If there's a failure, we need to re-subscribe upon all reconnections. This removes the derphttp.Client.WatchConnectionChanges method, which was basically impossible to use correctly, and changes it to be a boolean field on derphttp.Client alongside MeshKey and IsProber. Then it moves the call to the underlying derp.Client.WatchConnectionChanges to derphttp's client connection code, so it's resubscribed on any reconnect. Some paranoia is then added to make sure people hold the API right, not calling derphttp.Client.RunWatchConnectionLoop on an already-started Client without having set the bool to true. (But still auto-setting it to true if that's the first method that's been called on that derphttp.Client, as is commonly the case, and prevents existing code from breaking) Fixes tailscale/corp#9916 Supercedes tailscale/tailscale#9719 Co-authored-by: Val <valerie@tailscale.com> Co-authored-by: Irbe Krumina <irbe@tailscale.com> Co-authored-by: Anton Tolchanov <anton@tailscale.com> Signed-off-by: Brad Fitzpatrick <brad@danga.com>	8 months ago

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.
