Nick Khyl	1a2185b1ee	ipn/ipnlocal: rename setAutoExitNodeIDLockedOnEntry to pickNewAutoExitNode; drop old function Currently, (*LocalBackend).pickNewAutoExitNode() is just a wrapper around setAutoExitNodeIDLockedOnEntry that sends a prefs-change notification at the end. It doesn't need to do that, since setPrefsLockedOnEntry already sends the notification (setAutoExitNodeIDLockedOnEntry calls it via editPrefsLockedOnEntry). This PR removes the old pickNewAutoExitNode function and renames setAutoExitNodeIDLockedOnEntry to pickNewAutoExitNode for clarity.

Percy Wegmann	454d856be8	drive,ipn/ipnlocal: calculate peer taildrive URLs on-demand Instead of calculating the PeerAPI URL at the time that we add the peer, we now calculate it on every access to the peer. This way, if we initially did not have a shared address family with the peer, but later do, this allows us to access the peer at that point. This follows the pattern from other places where we access the peer API, which also calculate the URL on an as-needed basis. Additionally, we now show peers as not Available when we can't get a peer API URL. Lastly, this moves some of the more frequent verbose Taildrive logging from [v1] to [v2] level.

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).

Brad Fitzpatrick	3bc10ea585	ipn/ipnext: remove some interface indirection to add hooks Now that `25c4dc5fd7` removed unregistering hooks and made them into slices, just expose the slices and remove the setter funcs. This removes boilerplate ceremony around adding new hooks. This does export the hooks and make them mutable at runtime in theory, but that'd be a data race. If we really wanted to lock it down in the future we could make the feature.Hooks slice type be an opaque struct with an All() iterator and a "frozen" bool and we could freeze all the hooks after init. But that doesn't seem worth it. This means that hook registration is also now all in one place, rather than being mixed into ProfilesService vs ipnext.Host vs FooService vs BarService. I view that as a feature. When we have a ton of hooks and the list is long, then we can rearrange the fields in the Hooks struct as needed, or make sub-structs, or big comments.

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	60614fa4e5	ipn/desktop: fix panics on Windows 10, x86 [G,S]etWindowLongPtrW are not available on 32-bit Windows, where [G,S]etWindowLongW should be used instead. The initial revision of #14945 imported the win package for calling and other Win32 API functions, which exported the correct API depending on the platform. However, the same logic wasn't implemented when we removed the win package dependency in a later revision, resulting in panics on Windows 10 x86 (there's no 32-bit Windows 11). In this PR, we update the ipn/desktop package to use either [G,S]etWindowLongPtrW or [G,S]etWindowLongW depending on the platform.

Jonathan Nobels	d6fd865d41	hostinfo, ipnlocal: add optional os-specific callback for querying the hostname (#15647 ) updates tailscale/tailscale#13476 On darwin, os.Hostname is no longer reliable when called from a sandboxed process. To fix this, we will allow clients to set an optional callback to query the hostname via an alternative native API. We will leave the default implementation as os.Hostname since this works perfectly well for almost everything besides sandboxed darwin clients.

Nick Khyl	f28c8d0ec0	ipn/ipn{ext,local}: allow extension lookup by name or type In this PR, we add two methods to facilitate extension lookup by both extensions, and non-extensions (e.g., PeerAPI or LocalAPI handlers): - FindExtensionByName returns an extension with the specified name. It can then be type asserted to a given type. - FindMatchingExtension is like errors.As, but for extensions. It returns the first extension that matches the target type (either a specific extension or an interface).

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.

Jordan Whited	e17abbf461	cmd/tailscale,ipn: add relay-server-port "tailscale set" flag and Prefs field (#15594 ) This flag is currently no-op and hidden. The flag does round trip through the related pref. Subsequent commits will tie them to net/udprelay.Server. There is no corresponding "tailscale up" flag, enabling/disabling of the relay server will only be supported via "tailscale set". This is a string flag in order to support disablement via empty string as a port value of 0 means "enable the server and listen on a random unused port". Disablement via empty string also follows existing flag convention, e.g. advertise-routes. Early internal discussions settled on "tailscale set --relay="<port>", but the author felt this was too ambiguous around client vs server, and may cause confusion in the future if we add related flags.

Nick Khyl	6a9a7f35d9	cmd/tailscaled,ipn/{auditlog,ipnlocal},tsd: omit auditlog unless explicitly imported In this PR, we update ipnlocal.LocalBackend to allow registering callbacks for control client creation and profile changes. We also allow to register ipnauth.AuditLogFunc to be called when an auditable action is attempted. We then use all this to invert the dependency between the auditlog and ipnlocal packages and make the auditlog functionality optional, where it only registers its callbacks via ipnlocal-provided hooks when the auditlog package is imported. We then underscore-import it when building tailscaled for Windows, and we'll explicitly import it when building xcode/ipn-go-bridge for macOS. Since there's no default log-store location for macOS, we'll also need to call auditlog.SetStoreFilePath to specify where pending audit logs should be persisted.

Simon Law	e9324236e8	cmd/tailscale: fix default for `tailscale set --accept-routes` The default values for `tailscale up` and `tailscale set` are supposed to agree for all common flags. But they don’t for `--accept-routes` on Windows and from the Mac OS App Store, because `tailscale up` computes this value based on the operating system: user@host:~$ tailscale up --help 2>&1 \| grep -A1 accept-routes --accept-dns, --accept-dns=false accept DNS configuration from the admin panel (default true) user@host:~$ tailscale set --help 2>&1 \| grep -A1 accept-routes --accept-dns, --accept-dns=false accept DNS configuration from the admin panel Luckily, `tailscale set` uses `ipn.MaskedPrefs`, so the default values don’t logically matter. But someone will get the wrong idea if they trust the `tailscale set --help` documentation. In addition, `ipn.Prefs.RouteAll` defaults to true so it disagrees with both of the flags above. This patch makes `--accept-routes` use the same logic for in both commands by hoisting the logic that was buried in `cmd/tailscale/cli` to `ipn.Prefs.DefaultRouteAll`. Then, all three of defaults can agree. Fixes: #15319 Signed-off-by: Simon Law <sfllaw@sfllaw.ca>	8 months ago

Nick Khyl	f3f2f72f96	ipn/ipnlocal: do not attempt to start the auditlogger with a nil transport (*LocalBackend).setControlClientLocked() is called to both set and reset b.cc. We shouldn't attempt to start the audit logger when b.cc is being reset (i.e., cc is nil). However, it's fine to start the audit logger if b.cc implements auditlog.Transport, even if it's not a controlclient.Auto but a mock control client. In this PR, we fix both issues and add an assertion that controlclient.Auto is an auditlog.Transport. This ensures a compile-time failure if controlclient.Auto ever stops being a valid transport due to future interface or implementation changes.

Nick Khyl	e07c1573f6	ipn/ipnlocal: do not reset the netmap and packet filter in (LocalBackend).Start() Resetting LocalBackend's netmap without also unconfiguring wgengine to reset routes, DNS, and the killswitch firewall rules may cause connectivity issues until a new netmap is received. In some cases, such as when bootstrap DNS servers are inaccessible due to network restrictions or other reasons, or if the control plane is experiencing issues, this can result in a complete loss of connectivity until the user disconnects and reconnects to Tailscale. As LocalBackend handles state resets in (LocalBackend).resetForProfileChangeLockedOnEntry(), and this includes resetting the netmap, resetting the current netmap in (LocalBackend).Start() is not necessary. Moreover, it's harmful if (LocalBackend).Start() is called more than once for the same profile. In this PR, we update resetForProfileChangeLockedOnEntry() to reset the packet filter and remove the redundant resetting of the netmap and packet filter from Start(). We also update the state machine tests and revise comments that became inaccurate due to previous test updates.
