Brad Fitzpatrick	f715ee2be9	cmd/tailscaled: start implementing ts_omit_netstack Baby steps. This permits building without much of gvisor, but not all of it. Updates #17283 Change-Id: I8433146e259918cc901fe86b4ea29be22075b32c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago
Claus Lensbøl	2015ce4081	health,ipn/ipnlocal: introduce eventbus in heath.Tracker (#17085 ) The Tracker was using direct callbacks to ipnlocal. This PR moves those to be triggered via the eventbus. Additionally, the eventbus is now closed on exit from tailscaled explicitly, and health is now a SubSystem in tsd. Updates #15160 Signed-off-by: Claus Lensbøl <claus@tailscale.com>	3 months ago
Claus Lensbøl	b816fd7117	control/controlclient: introduce eventbus messages instead of callbacks (#16956 ) This is a small introduction of the eventbus into controlclient that communicates with mainly ipnlocal. While ipnlocal is a complicated part of the codebase, the subscribers here are from the perspective of ipnlocal already called async.

Brad Fitzpatrick	2b3e533048	util/syspolicy: finish plumbing policyclient, add feature/syspolicy, move global impl This is step 4 of making syspolicy a build-time feature. This adds a policyclient.Get() accessor to return the correct implementation to use: either the real one, or the no-op one. (A third type, a static one for testing, also exists, so in general a policyclient.Client should be plumbed around and not always fetched via policyclient.Get whenever possible, especially if tests need to use alternate syspolicy) Updates #16998 Updates #12614 Change-Id: Iaf19670744a596d5918acfa744f5db4564272978 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 months ago

Brad Fitzpatrick	1ca4ae598a	ipn/ipnlocal: use policyclient.Client always, stop using global syspolicy funcs Step 4 of N. See earlier commits in the series (via the issue) for the plan. This adds the missing methods to policyclient.Client and then uses it everywhere in ipn/ipnlocal and locks it in with a new dep test. Still plenty of users of the global syspolicy elsewhere in the tree, but this is a lot of them.

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.

M. J. Fromberger	ffb22ee353	all: construct new System values with an event bus pre-populated Although, at the moment, we do not yet require an event bus to be present, as we start to add more pieces we will want to ensure it is always available. Add a new constructor and replace existing uses of new(tsd.System) throughout. Update generated files for import changes.

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	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.

Nick Khyl	6df5c8f32e	various: keep tailscale connected when Always On mode is enabled on Windows In this PR, we enable the registration of LocalBackend extensions to exclude code specific to certain platforms or environments. We then introduce desktopSessionsExt, which is included only in Windows builds and only if the ts_omit_desktop_sessions tag is disabled for the build. This extension tracks desktop sessions and switches to (or remains on) the appropriate profile when a user signs in or out, locks their screen, or disconnects a remote session. As desktopSessionsExt requires an ipn/desktop.SessionManager, we register it with tsd.System for the tailscaled subprocess on Windows. We also fix a bug in the sessionWatcher implementation where it attempts to close a nil channel on stop.

Brad Fitzpatrick	723c775dbb	tsd, ipnlocal, etc: add tsd.System.HealthTracker, start some plumbing This adds a health.Tracker to tsd.System, accessible via a new tsd.System.HealthTracker method. In the future, that new method will return a tsd.System-specific HealthTracker, so multiple tsnet.Servers in the same process are isolated. For now, though, it just always returns the temporary health.Global value. That permits incremental plumbing over a number of changes. When the second to last health.Global reference is gone, then the tsd.System.HealthTracker implementation can return a private Tracker. The primary plumbing this does is adding it to LocalBackend and its dozen and change health calls. A few misc other callers are also plumbed. Subsequent changes will flesh out other parts of the tree (magicsock, controlclient, etc).
