Brad Fitzpatrick	f3d2fd22ef	cmd/tailscale/cli: don't start WatchIPNBus until after up's initial Start ... The CLI "up" command is a historical mess, both on the CLI side and the LocalBackend side. We're getting closer to cleaning it up, but in the meantime it was again implicated in flaky tests. In this case, the background goroutine running WatchIPNBus was very occasionally running enough to get to its StartLoginInteractive call before the original goroutine did its Start call. That meant integration tests were very rarely but sometimes logging in with the default control plane URL out on the internet (controlplane.tailscale.com) instead of the localhost control server for tests. This also might've affected new Headscale etc users on initial "up".

Nick Khyl	caa3d7594f	ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial ... We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP. This is primarily necessary to properly dial internal DNS servers accessible over Tailscale and subnet routes. However, to avoid issues when switching between Wi-Fi and cellular, we need to ensure that we don't retain connections to any external addresses on the old interface. Therefore, we need to determine which dialer to use internally based on the configured routes. This plumbs routes and localRoutes from router.Config to tsdial.Dialer, and updates UserDial to use either the peer dialer or the system dialer, depending on the network address and the configured routes.

Brad Fitzpatrick	15fc6cd966	derp/derphttp: fix netcheck HTTPS probes ... The netcheck client, when no UDP is available, probes distance using HTTPS. Several problems: * It probes using /derp/latency-check. * But cmd/derper serves the handler at /derp/probe * Despite the difference, it work by accident until c8f4dfc8c0 which made netcheck's probe require a 2xx status code. * in tests, we only use derphttp.Handler, so the cmd/derper-installed mux routes aren't preesnt, so there's no probe. That breaks tests in airplane mode. netcheck.Client then reports "unexpected HTTP status 426" (Upgrade Required) This makes derp handle both /derp/probe and /derp/latency-check equivalently, and in both cmd/derper and derphttp.Handler standalone modes. I notice this when wgengine/magicsock TestActiveDiscovery was failing in airplane mode (no wifi). It still doesn't pass, but it gets further.

Irbe Krumina	19b31ac9a6	cmd/{k8s-operator,k8s-nameserver},k8s-operator: update nameserver config with records for ingress/egress proxies (#11019) ... cmd/k8s-operator: optionally update dnsrecords Configmap with DNS records for proxies. This commit adds functionality to automatically populate DNS records for the in-cluster ts.net nameserver to allow cluster workloads to resolve MagicDNS names associated with operator's proxies. The records are created as follows: * For tailscale Ingress proxies there will be a record mapping the MagicDNS name of the Ingress device and each proxy Pod's IP address. * For cluster egress proxies, configured via tailscale.com/tailnet-fqdn annotation, there will be a record for each proxy Pod, mapping the MagicDNS name of the exposed tailnet workload to the proxy Pod's IP. No records will be created for any other proxy types. Records will only be created if users have configured the operator to deploy an in-cluster ts.net nameserver by applying tailscale.com/v1alpha1.DNSConfig. It is user's responsibility to add the ts.net nameserver as a stub nameserver for ts.net DNS names. https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/#configuration-of-stub-domain-and-upstream-nameserver-using-coredns https://cloud.google.com/kubernetes-engine/docs/how-to/kube-dns#upstream_nameservers See also https://github.com/tailscale/tailscale/pull/11017 Updates tailscale/tailscale#10499 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	7 months ago

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.

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>	7 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).

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.

Joe Tsai	7a77a2edf1	logtail: optimize JSON processing (#11671) ... Changes made: * Avoid "encoding/json" for JSON processing, and instead use "github.com/go-json-experiment/json/jsontext". Use jsontext.Value.IsValid for validation, which is much faster. Use jsontext.AppendQuote instead of our own JSON escaping. * In drainPending, use a different maxLen depending on lowMem. In lowMem mode, it is better to perform multiple uploads than it is to construct a large body that OOMs the process. * In drainPending, if an error is encountered draining, construct an error message in the logtail JSON format rather than something that is invalid JSON. * In appendTextOrJSONLocked, use jsontext.Decoder to check whether the input is a valid JSON object. This is faster than the previous approach of unmarshaling into map[string]any and then re-marshaling that data structure. This is especially beneficial for network flow logging, which produces relatively large JSON objects. * In appendTextOrJSONLocked, enforce maxSize on the input. If too large, then we may end up in a situation where the logs can never be uploaded because it exceeds the maximum body size that the Tailscale logs service accepts. * Use "tailscale.com/util/truncate" to properly truncate a string on valid UTF-8 boundaries. * In general, remove unnecessary spaces in JSON output.

Notes: * The logic for file detection is inlined based on what `kind` does. Technically it's a race condition, since the file could be removed/added in between the processing steps, but the fallout shouldn't be too bad. https://github.com/kubernetes-sigs/kind/blob/v0.23.0-alpha/pkg/cluster/internal/kubeconfig/internal/kubeconfig/paths.go * The sandboxed (App Store) variant relies on a specific temporary entitlement to access the ~/.kube/config file. The entitlement is only granted to specific files, and so is not applicable to paths supplied by the user at runtime. While there may be other ways to achieve this access to arbitrary kubeconfig files, it's out of scope for now. Updates #11645 Signed-off-by: Chloé Vulquin <code@toast.bunkerlabs.net>	7 months ago

ProxyClass custom resource can be used to specify customizations for the proxy resources created by the operator. Add a reconciler that validates ProxyClass resources and sets a Ready condition to True or False with a corresponding reason and message. This is required because some fields (labels and annotations) require complex validations that cannot be performed at custom resource apply time. Reconcilers that use the ProxyClass to configure proxy resources are expected to verify that the ProxyClass is Ready and not proceed with resource creation if configuration from a ProxyClass that is not yet Ready is required. If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet. If a tailscale Ingress has a tailscale.com/proxy-class annotation and the referenced ProxyClass custom resource is available and Ready, apply configuration from the ProxyClass to the proxy resources that will be created for the Ingress. Add a new .proxyClass field to the Connector spec. If connector.spec.proxyClass is set to a ProxyClass that is available and Ready, apply configuration from the ProxyClass to the proxy resources created for the Connector. Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml.

James Tucker	24bac27632	util/rands: add Shuffle and Perm functions with on-stack RNG state ... The new math/rand/v2 package includes an m-local global random number generator that can not be reseeded by the user, which is suitable for most uses without the RNG pools we have in a number of areas of the code base. The new API still does not have an allocation-free way of performing a seeded operations, due to the long term compiler bug around interface parameter escapes, and the Source interface. This change introduces the two APIs that math/rand/v2 can not yet replace efficiently: seeded Perm() and Shuffle() operations. This implementation chooses to use the PCG random source from math/rand/v2, as with sufficient compiler optimization, this source should boil down to only two on-stack registers for random state under ideal conditions.

In that environment, both the TS_API_KEY and OAuth variables will be set, even if they are empty values. This causes an error in gitops-pusher which expects only one to be set.
