Brad Fitzpatrick	e968b0ecd7	cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda chaotic and they both need to be redone/deleted (respectively), but this fixes some buggy behavior meanwhile. We were previously calling StartLoginInteractive (to start the controlclient's RegisterRequest) redundantly in some cases, causing test flakes depending on timing and up's weird state machine. We only need to call StartLoginInteractive in the client if Start itself doesn't. But Start doesn't tell us that. So cheat a bit and a put the information about whether there's a current NodeKey in the ipn.Status. It used to be accessible over LocalAPI via GetPrefs as a private key but we removed that for security. But a bool is fine. So then only call StartLoginInteractive if that bool is false and don't do it in the WatchIPNBus loop.

Maisem Ali	af97e7a793	tailcfg,all: add/plumb Node.IsJailed This adds a new bool that can be sent down from control to do jailing on the client side. Previously this would only be done from control by modifying the packet filter we sent down to clients. This would result in a lot of additional work/CPU on control, we could instead just do this on the client. This has always been a TODO which we keep putting off, might as well do it now.

Brad Fitzpatrick	b9adbe2002	net/{interfaces,netmon}, all: merge net/interfaces package into net/netmon In prep for most of the package funcs in net/interfaces to become methods in a long-lived netmon.Monitor that can cache things.

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).

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491 ) Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

Irbe Krumina	1a08ea5990	cmd/k8s-operator: operator can create subnetrouter (#9505 ) * k8s-operator,cmd/k8s-operator,Makefile,scripts,.github/workflows: add Connector kube CRD. Connector CRD allows users to configure the Tailscale Kubernetes operator to deploy a subnet router to expose cluster CIDRs or other CIDRs available from within the cluster to their tailnet. Also adds various CRD related machinery to generate CRD YAML, deep copy implementations etc. Engineers will now have to run 'make kube-generate-all` after changing kube files to ensure that all generated files are up to date. * cmd/k8s-operator,k8s-operator: reconcile Connector resources Reconcile Connector resources, create/delete subnetrouter resources in response to changes to Connector(s). Connector reconciler will not be started unless ENABLE_CONNECTOR env var is set to true. This means that users who don't want to use the alpha Connector custom resource don't have to install the Connector CRD to their cluster. For users who do want to use it the flow is: - install the CRD - install the operator (via Helm chart or using static manifests). For Helm users set .values.enableConnector to true, for static manifest users, set ENABLE_CONNECTOR to true in the static manifest.

Sonia Appasamy	89953b015b	ipn/ipnlocal,client/web: add web client to tailscaled Allows for serving the web interface from tailscaled, with the ability to start and stop the server via localapi endpoints (/web/start and /web/stop). This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.
