To match the format of exit node suggestions and ensure that the result is not ambiguous, relax exit node CLI selection to permit using a FQDN including the trailing dot.

Nick Khyl	fc28c8e7f3	cmd/cloner, cmd/viewer, util/codegen: add support for generic types and interfaces ... This adds support for generic types and interfaces to our cloner and viewer codegens. It updates these packages to determine whether to make shallow or deep copies based on the type parameter constraints. Additionally, if a template parameter or an interface type has View() and Clone() methods, we'll use them for getters and the cloner of the owning structure.

Andrew Lytvynov	b8af91403d	clientupdate: return true for CanAutoUpdate for macsys (#12746) ... While `clientupdate.Updater` won't be able to apply updates on macsys, we use `clientupdate.CanAutoUpdate` to gate the EditPrefs endpoint in localAPI. We should allow the GUI client to set AutoUpdate.Apply on macsys for it to properly get reported to the control plane. This also allows the tailnet-wide default for auto-updates to propagate to macsys clients.

Irbe Krumina	ba517ab388	cmd/k8s-operator,ssh/tailssh,tsnet: optionally record 'kubectl exec' sessions via Kubernetes operator's API server proxy (#12274) ... cmd/k8s-operator,ssh/tailssh,tsnet: optionally record kubectl exec sessions The Kubernetes operator's API server proxy, when it receives a request for 'kubectl exec' session now reads 'RecorderAddrs', 'EnforceRecorder' fields from tailcfg.KubernetesCapRule. If 'RecorderAddrs' is set to one or more addresses (of a tsrecorder instance(s)), it attempts to connect to those and sends the session contents to the recorder before forwarding the request to the kube API server. If connection cannot be established or fails midway, it is only allowed if 'EnforceRecorder' is not true (fail open).

Tom Proctor	01a7726cf7	cmd/containerboot,cmd/k8s-operator: enable IPv6 for fqdn egress proxies (#12577) ... cmd/containerboot,cmd/k8s-operator: enable IPv6 for fqdn egress proxies Don't skip installing egress forwarding rules for IPv6 (as long as the host supports IPv6), and set headless services `ipFamilyPolicy` to `PreferDualStack` to optionally enable both IP families when possible. Note that even with `PreferDualStack` set, testing a dual-stack GKE cluster with the default DNS setup of kube-dns did not correctly set both A and AAAA records for the headless service, and instead only did so when switching the cluster DNS to Cloud DNS. For both IPv4 and IPv6 to work simultaneously in a dual-stack cluster, we require headless services to return both A and AAAA records. If the host doesn't support IPv6 but the FQDN specified only has IPv6 addresses available, containerboot will exit with error code 1 and an error message because there is no viable egress route.

Charlotte Brandhorst-Satzkorn	42f01afe26	cmd/tailscale/cli: exit node filter should display all exit node options (#12699) ... This change expands the `exit-node list -filter` command to display all location based exit nodes for the filtered country. This allows users to switch to alternative servers when our recommended exit node is not working as intended. This change also makes the country filter matching case insensitive, e.g. both USA and usa will work.

Andrea Gottardo	8eb15d3d2d	cli/netcheck: fail with output if we time out fetching a derpmap (#12528) ... Updates tailscale/corp#20969 Right now, when netcheck starts, it asks tailscaled for a copy of the DERPMap. If it doesn't have one, it makes a HTTPS request to controlplane.tailscale.com to fetch one. This will always fail if you're on a network with a captive portal actively blocking HTTPS traffic. The code appears to hang entirely because the http.Client doesn't have a Timeout set. It just sits there waiting until the request succeeds or fails. This adds a timeout of 10 seconds, and logs more details about the status of the HTTPS request. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	5 months ago

Adds a new TailscaleProxyReady condition type for use in corev1.Service conditions. Also switch our CRDs to use metav1.Condition instead of ConnectorCondition. The Go structs are seralized identically, but it updates some descriptions and validation rules. Update k8s controller-tools and controller-runtime deps to fix the documentation generation for metav1.Condition so that it excludes comments and TODOs. Stop expecting the fake client to populate TypeMeta in tests. See kubernetes-sigs/controller-runtime#2633 for details of the change.

Irbe Krumina	8cc2738609	cmd/{containerboot,k8s-operator}: store proxy device ID early to help with cleanup for broken proxies (#12425) ... * cmd/containerboot: store device ID before setting up proxy routes. For containerboot instances whose state needs to be stored in a Kubernetes Secret, we additonally store the device's ID, FQDN and IPs. This is used, between other, by the Kubernetes operator, who uses the ID to delete the device when resources need cleaning up and writes the FQDN and IPs on various kube resource statuses for visibility. This change shifts storing device ID earlier in the proxy setup flow, to ensure that if proxy routing setup fails, the device can still be deleted.

Brad Fitzpatrick	64ac64fb66	net/tsaddr: use bart in NewContainsIPFunc, add tests, benchmarks ... NewContainsIPFunc was previously documented as performing poorly if there were many netip.Prefixes to search over. As such, we never it used it in such cases. This updates it to use bart at a certain threshold (over 6 prefixes, currently), at which point the bart lookup overhead pays off. This is currently kinda useless because we're not using it. But now we can and get wins elsewhere.
