Nick Khyl	e815ae0ec4	util/syspolicy, ipn/ipnlocal: update syspolicy package to utilize syspolicy/rsop In this PR, we update the syspolicy package to utilize syspolicy/rsop under the hood, and remove syspolicy.CachingHandler, syspolicy.windowsHandler and related code which is no longer used. We mark the syspolicy.Handler interface and RegisterHandler/SetHandlerForTest functions as deprecated, but keep them temporarily until they are no longer used in other repos. We also update the package to register setting definitions for all existing policy settings and to register the Registry-based, Windows-specific policy stores when running on Windows. Finally, we update existing internal and external tests to use the new API and add a few more tests and benchmarks. Updates #12687 Signed-off-by: Nick Khyl <nickk@tailscale.com>	4 weeks ago
Nick Khyl	874db2173b	ipn/{ipnauth,ipnlocal,ipnserver}: send the auth URL to the user who started interactive login We add the ClientID() method to the ipnauth.Actor interface and updated ipnserver.actor to implement it. This method returns a unique ID of the connected client if the actor represents one. It helps link a series of interactions initiated by the client, such as when a notification needs to be sent back to a specific session, rather than all active sessions, in response to a certain request. We also add LocalBackend.WatchNotificationsAs and LocalBackend.StartLoginInteractiveAs methods, which are like WatchNotifications and StartLoginInteractive but accept an additional parameter specifying an ipnauth.Actor who initiates the operation. We store these actor identities in watchSession.owner and LocalBackend.authActor, respectively,and implement LocalBackend.sendTo and related helper methods to enable sending notifications to watchSessions associated with actors (or, more broadly, identifiable recipients). We then use the above to change who receives the BrowseToURL notifications: - For user-initiated, interactive logins, the notification is delivered only to the user who initiated the process. If the initiating actor represents a specific connected client, the URL notification is sent back to the same LocalAPI client that called StartLoginInteractive. Otherwise, the notification is sent to all clients connected as that user. Currently, we only differentiate between users on Windows, as it is inherently a multi-user OS. - In all other cases (e.g., node key expiration), we send the notification to all connected users.

Andrea Gottardo	d060b3fa02	cli: implement `tailscale dns status` (#13353 ) Updates tailscale/tailscale#13326 This PR begins implementing a `tailscale dns` command group in the Tailscale CLI. It provides an initial implementation of `tailscale dns status` which dumps the state of the internal DNS forwarder. Two new endpoints were added in LocalAPI to support the CLI functionality: - `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy) - `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information) My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

Nick Khyl	5bc9fafab8	ipn/ipnlocal: always send auth URL notifications when a user requests interactive login This PR changes how LocalBackend handles interactive (initiated via StartLoginInteractive) and non-interactive (e.g., due to key expiration) logins, and when it sends the authURL to the connected clients. Specifically, - When a user initiates an interactive login by clicking Log In in the GUI, the LocalAPI calls StartLoginInteractive. If an authURL is available and hasn't expired, we immediately send it to all connected clients, suggesting them to open that URL in a browser. Otherwise, we send a login request to the control plane and set a flag indicating that an interactive login is in progress. - When LocalBackend receives an authURL from the control plane, we check if it differs from the previous one and whether an interactive login is in progress. If either condition is true, we notify all connected clients with the new authURL and reset the interactive login flag. We reset the auth URL and flags upon a successful authentication, when a different user logs in and when switching Tailscale login profiles. Finally, we remove the redundant dedup logic added to WatchNotifications in #12096 and revert the tests to their original state to ensure that calling StartLoginInteractive always produces BrowseToURL notifications, either immediately or when the authURL is received from the control plane.

Nick Khyl	b48c8db69c	ipn/ipnlocal: set WantRunning upon an interactive login, but not during a seamless renewal or a profile switch The LocalBackend's state machine starts in NoState and soon transitions to NeedsLogin if there's no auto-start profile, with the profileManager starting with a new empty profile. Notably, entering the NeedsLogin state blocks engine updates. We expect the user to transition out of this state by logging in interactively, and we set WantRunning to true when controlclient enters the StateAuthenticated state. While our intention is correct, and completing an interactive login should set WantRunning to true, our assumption that logging into the current Tailscale profile is the only way to transition out of the NeedsLogin state is not accurate. Another common transition path includes an explicit profile switch (via LocalBackend.SwitchProfile) or an implicit switch when a Windows user connects to the backend. This results in a bug where WantRunning is set to true even when it was previously set to false, and the user expressed no intention of changing it. A similar issue occurs when switching from (sic) a Tailnet that has seamlessRenewalEnabled, regardless of the current state of the LocalBackend's state machine, and also results in unexpectedly set WantRunning. While this behavior is generally undesired, it is also incorrect that it depends on the control knobs of the Tailnet we're switching from rather than the Tailnet we're switching to. However, this issue needs to be addressed separately. This PR updates LocalBackend.SetControlClientStatus to only set WantRunning to true in response to an interactive login as indicated by a non-empty authURL.

Nick Khyl	80b2b45d60	ipn/ipnlocal: refactor and cleanup profileManager In preparation for multi-user and unattended mode improvements, we are refactoring and cleaning up `ipn/ipnlocal.profileManager`. The concept of the "current user", which is only relevant on Windows, is being deprecated and will soon be removed to allow more than one Windows user to connect and utilize `LocalBackend` according to that user's access rights to the device and specific Tailscale profiles. We plan to pass the user's identity down to the `profileManager`, where it can be used to determine the user's access rights to a given `LoginProfile`. While the new permission model in `ipnauth` requires more work and is currently blocked pending PR reviews, we are updating the `profileManager` to reduce its reliance on the concept of a single OS user being connected to the backend at the same time. We extract the switching to the default Tailscale profile, which may also trigger legacy profile migration, from `profileManager.SetCurrentUserID`. This introduces `profileManager.DefaultUserProfileID`, which returns the default profile ID for the current user, and `profileManager.SwitchToDefaultProfile`, which is essentially a shorthand for `pm.SwitchProfile(pm.DefaultUserProfileID())`. Both methods will eventually be updated to accept the user's identity and utilize that user's default profile. We make access checks more explicit by introducing the `profileManager.checkProfileAccess` method. The current implementation continues to use `profileManager.currentUserID` and `LoginProfile.LocalUserID` to determine whether access to a given profile should be granted. This will be updated to utilize the `ipnauth` package and the new permissions model once it's ready. We also expand access checks to be used more widely in the `profileManager`, not just when switching or listing profiles. This includes access checks in methods like `SetPrefs` and, most notably, `DeleteProfile` and `DeleteAllProfiles`, preventing unprivileged Windows users from deleting Tailscale profiles owned by other users on the same device, including profiles owned by local admins. We extract `profileManager.ProfilePrefs` and `profileManager.SetProfilePrefs` methods that can be used to get and set preferences of a given `LoginProfile` if `profileManager.checkProfileAccess` permits access to it. We also update `profileManager.setUnattendedModeAsConfigured` to always enable unattended mode on Windows if `Prefs.ForceDaemon` is true in the current `LoginProfile`, even if `profileManager.currentUserID` is `""`. This facilitates enabling unattended mode via `tailscale up --unattended` even if `tailscale-ipn.exe` is not running, such as when a Group Policy or MDM-deployed script runs at boot time, or when Tailscale is used on a Server Code or otherwise headless Windows environments.

Nick Khyl	961ee321e8	ipn/{ipnauth,ipnlocal,ipnserver,localapi}: start baby step toward moving access checks from the localapi.Handler to the LocalBackend Currently, we use PermitRead/PermitWrite/PermitCert permission flags to determine which operations are allowed for a LocalAPI client. These checks are performed when localapi.Handler handles a request. Additionally, certain operations (e.g., changing the serve config) requires the connected user to be a local admin. This approach is inherently racey and is subject to TOCTOU issues. We consider it to be more critical on Windows environments, which are inherently multi-user, and therefore we prevent more than one OS user from connecting and utilizing the LocalBackend at the same time. However, the same type of issues is also applicable to other platforms when switching between profiles that have different OperatorUser values in ipn.Prefs. We'd like to allow more than one Windows user to connect, but limit what they can see and do based on their access rights on the device (e.g., an local admin or not) and to the currently active LoginProfile (e.g., owner/operator or not), while preventing TOCTOU issues on Windows and other platforms. Therefore, we'd like to pass an actor from the LocalAPI to the LocalBackend to represent the user performing the operation. The LocalBackend, or the profileManager down the line, will then check the actor's access rights to perform a given operation on the device and against the current (and/or the target) profile. This PR does not change the current permission model in any way, but it introduces the concept of an actor and includes some preparatory work to pass it around. Temporarily, the ipnauth.Actor interface has methods like IsLocalSystem and IsLocalAdmin, which are only relevant to the current permission model. It also lacks methods that will actually be used in the new model. We'll be adding these gradually in the next PRs and removing the deprecated methods and the Permit* flags at the end of the transition.

Anton Tolchanov	151b77f9d6	cmd/tl-longchain: tool to re-sign nodes with long rotation signatures In Tailnet Lock, there is an implicit limit on the number of rotation signatures that can be chained before the signature becomes too long. This program helps tailnet admins to identify nodes that have signatures with long chains and prints commands to re-sign those node keys with a fresh direct signature. It's a temporary mitigation measure, and we will remove this tool as we design and implement a long-term approach for rotation signatures.

Andrew Lytvynov	e7bf6e716b	cmd/tailscale: add --min-validity flag to the cert command (#12822 ) Some users run "tailscale cert" in a cron job to renew their certificates on disk. The time until the next cron job run may be long enough for the old cert to expire with our default heristics. Add a `--min-validity` flag which ensures that the returned cert is valid for at least the provided duration (unless it's longer than the cert lifetime set by Let's Encrypt).
