Andrew Lytvynov	6feb3c35cb	ipn/store: automatically migrate between plaintext and encrypted state (#16318 ) Add a new `--encrypt-state` flag to `cmd/tailscaled`. Based on that flag, migrate the existing state file to/from encrypted format if needed. Updates #15830 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	5 months ago

Nick Khyl	fb188c5b53	net/dns,docs/windows/policy,util/syspolicy: register Tailscale IP addresses in AD DNS if required by policy In this PR, we make DNS registration behavior configurable via the EnableDNSRegistration policy setting. We keep the default behavior unchanged, but allow admins to either enforce DNS registration and dynamic DNS updates for the Tailscale interface, or prevent Tailscale from modifying the settings configured in the network adapter's properties or by other means.

Brad Fitzpatrick	265c76dbc5	all: unify some redundant testing.TB interface copies I added yet another one in `6d117d64a2` but that new one is at the best place int he dependency graph and has the best name, so let's use that one for everything possible. types/lazy can't use it for circular dependency reasons, so unexport that copy at least.

Nick Khyl	8d7033fe7f	ipn/ipnlocal,util/syspolicy,docs/windows/policy: implement the ReconnectAfter policy setting In this PR, we update the LocalBackend so that when the ReconnectAfter policy setting is configured and a user disconnects Tailscale by setting WantRunning to false in the profile prefs, the LocalBackend will now start a timer to set WantRunning back to true once the ReconnectAfter timer expires. We also update the ADMX/ADML policy definitions to allow configuring this policy setting for Windows via Group Policy and Intune.

Nick Khyl	d832467461	client/tailscale,ipn/ipn{local,server},util/syspolicy: implement the AlwaysOn.OverrideWithReason policy setting In this PR, we update client/tailscale.LocalClient to allow sending requests with an optional X-Tailscale-Reason header. We then update ipn/ipnserver.{actor,Server} to retrieve this reason, if specified, and use it to determine whether ipnauth.Disconnect is allowed when the AlwaysOn.OverrideWithReason policy setting is enabled. For now, we log the reason, along with the profile and OS username, to the backend log. Finally, we update LocalBackend to remember when a disconnect was permitted and do not reconnect automatically unless the policy changes.

Nick Khyl	02ad21717f	ipn/ipn{auth,server,local}: initial support for the always-on mode In this PR, we update LocalBackend to set WantRunning=true when applying policy settings to the current profile's prefs, if the "always-on" mode is enabled. We also implement a new (LocalBackend).EditPrefsAs() method, which is like EditPrefs but accepts an actor (e.g., a LocalAPI client's identity) that initiated the change. If WantRunning is being set to false, the new EditPrefsAs method checks whether the actor has ipnauth.Disconnect access to the profile and propagates an error if they do not. Finally, we update (ipnserver.actor).CheckProfileAccess to allow a disconnect only if the "always-on" mode is not enabled by the AlwaysOn policy setting. This is not a comprehensive solution to the "always-on" mode across platforms, as instead of disconnecting a user could achieve the same effect by creating a new empty profile, initiating a reauth, or by deleting the profile. These are the things we should address in future PRs. Updates #14823 Signed-off-by: Nick Khyl <nickk@tailscale.com>	10 months ago
Andrea Gottardo	c79b736a85	ipnlocal: allow overriding os.Hostname() via syspolicy (#14676 ) Updates tailscale/corp#25936 This defines a new syspolicy 'Hostname' and allows an IT administrator to override the value we normally read from os.Hostname(). This is particularly useful on Android and iOS devices, where the hostname we get from the OS is really just the device model (a platform restriction to prevent fingerprinting). If we don't implement this, all devices on the customer's side will look like `google-pixel-7a-1`, `google-pixel-7a-2`, `google-pixel-7a-3`, etc. and it is not feasible for the customer to use the API or worse the admin console to manually fix these names.

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>	1 year ago
Nick Khyl	11d205f6c4	control/controlclient,posture,util/syspolicy: use predefined syspolicy keys instead of string literals With the upcoming syspolicy changes, it's imperative that all syspolicy keys are defined in the syspolicy package for proper registration. Otherwise, the corresponding policy settings will not be read. This updates a couple of places where we still use string literals rather than syspolicy consts.

Andrea Gottardo	9d2b1820f1	ipnlocal: support setting authkey at login using syspolicy (#13061 ) Updates tailscale/corp#22120 Adds the ability to start the backend by reading an authkey stored in the syspolicy database (MDM). This is useful for devices that are provisioned in an unattended fashion. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	1 year ago
Nick Khyl	67df9abdc6	util/syspolicy/setting: add package that contains types for the next syspolicy PRs Package setting contains types for defining and representing policy settings. It facilitates the registration of setting definitions using Register and RegisterDefinition, and the retrieval of registered setting definitions via Definitions and DefinitionOf. This package is intended for use primarily within the syspolicy package hierarchy, and added in a preparation for the next PRs.

Adrian Dewhurst	86aa0485a6	ipn/ipnlocal, util/syspolicy: make run exit node a preference option Previously, the "RunExitNode" policy merely controlled the visibility of the "run as exit node" menu item, not the setting itself. This migrates that setting to a preference option named "AdvertiseExitNode".

Adrian Dewhurst	f706a3abd0	ipn/ipnlocal, util/syspolicy: add auto update policy Due to the Sparkle preference naming convention, macsys already has a policy key named "ApplyUpdates" that merely shows or hides the menu item that controls if auto updates are installed, rather than directly controlling the setting. For other platforms, we are going to use "InstallUpdates" instead because it seemed better than the other options that were considered.

Adrian Dewhurst	af32d1c120	ipn/ipnlocal: better enforce system policies Previously, policies affected the default prefs for a new profile, but that does not affect existing profiles. This change ensures that policies are applied whenever preferences are loaded or changed, so a CLI or GUI client that does not respect the policies will still be overridden. Exit node IP is dropped from this PR as it was implemented elsewhere in #10172.

Kristoffer Dalby	e06f2f1873	ipn/ipnlocal: change serial number policy to be PreferenceOption This commit changes the PostureChecking syspolicy key to be a PreferenceOption(user-defined, always, never) instead of Bool.
