Nick Khyl	bbc5107d7d	ipn/ipnlocal: do not reset extHost on (LocalBackend).Shutdown We made changes to ipnext callback registration/unregistration/invocation in #15780 that made resetting b.exthost to a nil, no-op host in (LocalBackend).Shutdown() unnecessary.

Brad Fitzpatrick	d05e6dc09e	util/syspolicy/policyclient: add policyclient.Client interface, start plumbing This is step 2 of ~4, breaking up #14720 into reviewable chunks, with the aim to make syspolicy be a build-time configurable feature. Step 1 was #16984. In this second step, the util/syspolicy/policyclient package is added with the policyclient.Client interface. This is the interface that's always present (regardless of build tags), and is what code around the tree uses to ask syspolicy/MDM questions. There are two implementations of policyclient.Client for now: 1) NoPolicyClient, which only returns default values. 2) the unexported, temporary 'globalSyspolicy', which is implemented in terms of the global functions we wish to later eliminate. This then starts to plumb around the policyclient.Client to most callers. Future changes will plumb it more. When the last of the global func callers are gone, then we can unexport the global functions and make a proper policyclient.Client type and constructor in the syspolicy package, removing the globalSyspolicy impl out of tsd. The final change will sprinkle build tags in a few more places and lock it in with dependency tests to make sure the dependencies don't later creep back in.

In this first (very noisy) step, all the syspolicy string key constants move to a new constant-only (code-free) package. This will make future steps more reviewable, without this movement noise. There are no code or behavior changes here. The future steps of this series can be seen in #14720: removing global funcs from syspolicy resolution and using an interface that's plumbed around instead. Then adding build tags.

Jonathan Nobels	80f5a00e76	ipn/local: add the suggested exit node to the ipn bus (#16748 ) fixes tailscale/corp#26369 The suggested exit node is currently only calculated during a localAPI request. For older UIs, this wasn't a bad choice - we could just fetch it on-demand when a menu presented itself. For newer incarnations however, this is an always-visible field that needs to react to changes in the suggested exit node's value. This change recalculates the suggested exit node ID on netmap updates and broadcasts it on the IPN bus. The localAPI version of this remains intact for the time being.

M. J. Fromberger	6c8fef961e	ipn/ipnlocal: replace the LockedOnEntry pattern with conventional lock/unlock discipline (#16925 ) There are several methods within the LocalBackend that used an unusual and error-prone lock discipline whereby they require the caller to hold the backend mutex on entry, but release it on the way out. In #11650 we added some support code to make this pattern more visible. Now it is time to eliminate the pattern (at least within this package). This is intended to produce no semantic changes, though I am relying on integration tests and careful inspection to achieve that. To the extent possible I preserved the existing control flow. In a few places, however, I replaced this with an unlock/lock closure. This means we will sometimes reacquire a lock only to release it again one frame up the stack, but these operations are not performance sensitive and the legibility gain seems worthwhile. We can probably also pull some of these out into separate methods, but I did not do that here so as to avoid other variable scope changes that might be hard to see. I would like to do some more cleanup separately. As a follow-up, we could also remove the unlockOnce helper, but I did not do that here either.

Simon Law	1ef8fbf470	ipn/ipnlocal: send Hostinfo after resolveExitNode for "auto:any" (#16632 ) In #16625, I introduced a mechanism for sending the selected exit node to Control via tailcfg.Hostinfo.ExitNodeID as part of the MapRequest. @nickkhyl pointed out that LocalBackend.doSetHostinfoFilterServices needs to be triggered in order to actually send this update.

Simon Law	e84e58c567	ipn/ipnlocal: use rendezvous hashing to traffic-steer exit nodes With auto exit nodes enabled, the client picks exit nodes from the ones advertised in the network map. Usually, it picks the one with the highest priority score, but when the top spot is tied, it used to pick randomly. Then, once it made a selection, it would strongly prefer to stick with that exit node. It wouldn’t even consider another exit node unless the client was shutdown or the exit node went offline. This is to prevent flapping, where a client constantly chooses a different random exit node. The major problem with this algorithm is that new exit nodes don’t get selected as often as they should. In fact, they wouldn’t even move over if a higher scoring exit node appeared. Let’s say that you have an exit node and it’s overloaded. So you spin up a new exit node, right beside your existing one, in the hopes that the traffic will be split across them. But since the client had this strong affinity, they stick with the exit node they know and love. Using rendezvous hashing, we can have different clients spread their selections equally across their top scoring exit nodes. When an exit node shuts down, its clients will spread themselves evenly to their other equal options. When an exit node starts, a proportional number of clients will migrate to their new best option. Read more: https://en.wikipedia.org/wiki/Rendezvous_hashing The trade-off is that starting up a new exit node may cause some clients to move over, interrupting their existing network connections. So this change is only enabled for tailnets with `traffic-steering` enabled. Updates tailscale/corp#29966 Fixes #16551 Signed-off-by: Simon Law <sfllaw@tailscale.com>	5 months ago

Simon Law	c18ba4470b	ipn/ipnlocal: add traffic steering support to exit-node suggestions (#16527 ) When `tailscale exit-node suggest` contacts the LocalAPI for a suggested exit node, the client consults its netmap for peers that contain the `suggest-exit-node` peercap. It currently uses a series of heuristics to determine the exit node to suggest. When the `traffic-steering` feature flag is enabled on its tailnet, the client will defer to Control’s priority scores for a particular peer. These scores, in `tailcfg.Hostinfo.Location.Priority`, were historically only used for Mullvad exit nodes, but they have now been extended to score any peer that could host a redundant resource. Client capability version 119 is the earliest client that understands these traffic steering scores. Control tells the client to switch to rely on these scores by adding `tailcfg.NodeAttrTrafficSteering` to its `AllCaps`.

Nick Khyl	f1c7b463cd	ipn/{ipnauth,ipnlocal,localapi}: make EditPrefs return an error if changing exit node is restricted by policy We extract checkEditPrefsAccessLocked, adjustEditPrefsLocked, and onEditPrefsLocked from the EditPrefs execution path, defining when each step is performed and what behavior is allowed at each stage. Currently, this is primarily used to support Always On mode, to handle the Exit Node enablement toggle, and to report prefs edit metrics. We then use it to enforce Exit Node policy settings by preventing users from setting an exit node and making EditPrefs return an error when an exit node is restricted by policy. This enforcement is also extended to the Exit Node toggle. These changes prepare for supporting Exit Node overrides when permitted by policy and preventing logout while Always On mode is enabled. In the future, implementation of these methods can be delegated to ipnext extensions via the feature hooks.

Nick Khyl	cb7b49941e	ipn/ipnlocal: add (LocalBackend).reconcilePrefsLocked We have several places where we call applySysPolicy, suggestExitNodeLocked, and setExitNodeID. While there are cases where we want to resolve the exit node specifically, such as when network conditions change or a new netmap is received, we typically need to perform all three steps. For example, enforcing policy settings may enable auto exit nodes or set an ExitNodeIP, which in turn requires picking a suggested exit node or resolving the IP to an ID, respectively. In this PR, we introduce (LocalBackend).resolveExitNodeInPrefsLocked and (*LocalBackend).reconcilePrefsLocked, with the latter calling both applySysPolicy and resolveExitNodeInPrefsLocked. Consolidating these steps into a single extensibility point would also make it easier to support future hooks registered by ipnext extensions.

Additionally, instead of suggestExitNodeLocked passing the most recent full netmap to suggestExitNode, we now pass the current nodeBackend so it can access peers with delta updates applied.

Nick Khyl	a8055b5f40	cmd/tailscale/cli,ipn,ipn/ipnlocal: add AutoExitNode preference for automatic exit node selection With this change, policy enforcement and exit node resolution can happen in separate steps, since enforcement no longer depends on resolving the suggested exit node. This keeps policy enforcement synchronous (e.g., when switching profiles), while allowing exit node resolution to be asynchronous on netmap updates, link changes, etc. Additionally, the new preference will be used to let GUIs and CLIs switch back to "auto" mode after a manual exit node override, which is necessary for tailscale/corp#29969.

Nick Khyl	824985afe1	feature/taildrop,ipn/ipn{ext,local}: initialize taildrop for initial profile Currently, LocalBackend/ExtensionHost doesn't invoke the profile change callback for the initial profile. Since the initial profile may vary depending on loaded extensions and applied policy settings, it can't be reliably determined until all extensions are initialized. Additionally, some extensions may asynchronously trigger a switch to the "best" profile (based on system state and policy settings) during initialization. We intended to address these issues as part of the ongoing profileManager/LocalBackend refactoring, but the changes didn't land in time for the v1.84 release and the Taildrop refactoring. In this PR, we update the Taildrop extension to retrieve the current profile at initialization time and handle it as a profile change. We also defer extension initialization until LocalBackend has started, since the Taildrop extension already relies on this behavior (e.g., it requires clients to call SetDirectFileRoot before Init).

Nick Khyl	e6eba4efee	ipn/{auditlog,ipnext,ipnlocal}: convert the profile-change callback to a profile-state-change callback In this PR, we enable extensions to track changes in the current prefs. These changes can result from a profile switch or from the user or system modifying the current profile’s prefs. Since some extensions may want to distinguish between the two events, while others may treat them similarly, we rename the existing profile-change callback to become a profile-state-change callback and invoke it whenever the current profile or its preferences change. Extensions can still use the sameNode parameter to distinguish between situations where the profile information, including its preferences, has been updated but still represents the same tailnet node, and situations where a switch to a different profile has been made. Having dedicated prefs-change callbacks is being considered, but currently seems redundant. A single profile-state-change callback is easier to maintain. We’ll revisit the idea of adding a separate callback as we progress on extracting existing features from LocalBackend, but the conversion to a profile-state-change callback is intended to be permanent. Finally, we let extensions retrieve the current prefs or profile state (profile info + prefs) at any time using the new CurrentProfileState and CurrentPrefs methods. We also simplify the NewControlClientCallback signature to exclude profile prefs. It’s optional, and extensions can retrieve the current prefs themselves if needed.

Nick Khyl	4941cd7c73	cmd/tailscaled,ipn/{auditlog,desktop,ipnext,ipnlocal},tsd: extract LocalBackend extension interfaces and implementation In this PR, we refactor the LocalBackend extension system, moving from direct callbacks to a more organized extension host model. Specifically, we: - Extract interface and callback types used by packages extending LocalBackend functionality into a new ipn/ipnext package. - Define ipnext.Host as a new interface that bridges extensions with LocalBackend. It enables extensions to register callbacks and interact with LocalBackend in a concurrency-safe, well-defined, and controlled way. - Move existing callback registration and invocation code from ipnlocal.LocalBackend into a new type called ipnlocal.ExtensionHost, implementing ipnext.Host. - Improve docs for existing types and methods while adding docs for the new interfaces. - Add test coverage for both the extracted and the new code. - Remove ipn/desktop.SessionManager from tsd.System since ipn/desktop is now self-contained. - Update existing extensions (e.g., ipn/auditlog and ipn/desktop) to use the new interfaces where appropriate. We're not introducing new callback and hook types (e.g., for ipn.Prefs changes) just yet, nor are we enhancing current callbacks, such as by improving conflict resolution when more than one extension tries to influence profile selection via a background profile resolver. These further improvements will be submitted separately.

Nick Khyl	94f4f83731	ipn, ipn/ipnlocal: reduce coupling between LocalBackend/profileManager and the Windows-specific "current user" model Ultimately, we'd like to get rid of the concept of the "current user". It is only used on Windows, but even then it doesn't work well in multi-user and enterprise/managed Windows environments. In this PR, we update LocalBackend and profileManager to decouple them a bit more from this obsolete concept. This is done in a preparation for extracting ipnlocal.Extension-related interfaces and types, and using them to implement optional features like tailscale/corp#27645, instead of continuing growing the core ipnlocal logic. Notably, we rename (*profileManager).SetCurrentUserAndProfile() to SwitchToProfile() and change its signature to accept an ipn.LoginProfileView instead of an ipn.ProfileID and ipn.WindowsUserID. Since we're not removing the "current user" completely just yet, the method sets the current user to the owner of the target profile. We also update the profileResolver callback type, which is typically implemented by LocalBackend extensions, to return an ipn.LoginProfileView instead of ipn.ProfileID and ipn.WindowsUserID.
