Joe Tsai	5db80cf2d8	syncs: fix AtomicValue for interface kinds (#11943 ) If AtomicValue[T] is used with a T that is an interface kind, then Store may panic if different concret types are ever stored. Fix this by always wrapping in a concrete type. Technically, this is only needed if T is an interface kind, but there is no harm in doing it also for non-interface kinds.

Irbe Krumina	44aa809cb0	cmd/{k8s-nameserver,k8s-operator},k8s-operator: add a kube nameserver, make operator deploy it (#11919 ) * cmd/k8s-nameserver,k8s-operator: add a nameserver that can resolve ts.net DNS names in cluster. Adds a simple nameserver that can respond to A record queries for ts.net DNS names. It can respond to queries from in-memory records, populated from a ConfigMap mounted at /config. It dynamically updates its records as the ConfigMap contents changes. It will respond with NXDOMAIN to queries for any other record types (AAAA to be implemented in the future). It can respond to queries over UDP or TCP. It runs a miekg/dns DNS server with a single registered handler for ts.net domain names. Queries for other domain names will be refused. The intended use of this is: 1) to allow non-tailnet cluster workloads to talk to HTTPS tailnet services exposed via Tailscale operator egress over HTTPS 2) to allow non-tailnet cluster workloads to talk to workloads in the same cluster that have been exposed to tailnet over their MagicDNS names but on their cluster IPs. DNSConfig CRD can be used to configure the operator to deploy kube nameserver (./cmd/k8s-nameserver) to cluster.

Shaw Drastin	1fe073098c	Reset dial plan when switching profile (#11933 ) When switching profile, the server URL can change (e.g. because of switching to a self-hosted headscale instance). If it is not reset here, dial plans returned by old server (e.g. tailscale control server) will be used to connect to new server (e.g. self-hosted headscale server), and the register request will be blocked by it until timeout, leading to very slow profile switches.

But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago

Irbe Krumina	df8f40905b	cmd/k8s-operator,k8s-operator: optionally serve tailscaled metrics on Pod IP (#11699 ) Adds a new .spec.metrics field to ProxyClass to allow users to optionally serve client metrics (tailscaled --debug) on <Pod-IP>:9001. Metrics cannot currently be enabled for proxies that egress traffic to tailnet and for Ingress proxies with tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation (because they currently forward all cluster traffic to their respective backends). The assumption is that users will want to have these metrics enabled continuously to be able to monitor proxy behaviour (as opposed to enabling them temporarily for debugging). Hence we expose them on Pod IP to make it easier to consume them i.e via Prometheus PodMonitor. Updates tailscale/tailscale#11292 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	2 months ago
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).

Brad Fitzpatrick	cb66952a0d	health: permit Tracker method calls on nil receiver In prep for tsd.System Tracker plumbing throughout tailscaled, defensively permit all methods on Tracker to accept a nil receiver without crashing, lest I screw something up later. (A health tracking system that itself causes crashes would be no good.) Methods on nil receivers should not be called, so a future change will also collect their stacks (and panic during dev/test), but we should at least not crash in prod. This also locks that in with a test using reflect to automatically call all methods on a nil receiver and check they don't crash.

Brad Fitzpatrick	ebc552d2e0	health: add Tracker type, in prep for removing global variables This moves most of the health package global variables to a new `health.Tracker` type.

Containerboot will periodically (every 10 minutes) attempt to resolve the DNS name and ensure that all traffic sent to the node's tailnet IP gets forwarded to the resolved backend IP addresses. Currently: - if the firewall mode is iptables, traffic will be load balanced accross the backend IP addresses using round robin. There are no health checks for whether the IPs are reachable. - if the firewall mode is nftables traffic will only be forwarded to the first IP address in the list. This is to be improved. * cmd/k8s-operator: support ExternalName Services Adds support for exposing endpoints, accessible from within a cluster to the tailnet via DNS names using ExternalName Services. This can be done by annotating the ExternalName Service with tailscale.com/expose: "true" annotation. The operator will deploy a proxy configured to route tailnet traffic to the backend IPs that service.spec.externalName resolves to. The backend IPs must be reachable from the operator's namespace.
