Jordan Whited	7aec8d4e6b	cmd/stunstamp: refactor connection construction (#13110 ) getConns() is now responsible for returning both stable and unstable conns. conn and measureFn are now passed together via connAndMeasureFn. newConnAndMeasureFn() is responsible for constructing them.

Maisem Ali	12764e9db4	natlab: add NodeAgentClient This adds a new NodeAgentClient type that can be used to invoke the LocalAPI using the LocalClient instead of handcrafted URLs. However, there are certain cases where it does make sense for the node agent to provide more functionality than whats possible with just the LocalClient, as such it also exposes a http.Client to make requests directly.

Andrew Lytvynov	c0c4791ce7	cmd/gitops-pusher: ignore previous etag if local acls match control (#13068 ) In a situation when manual edits are made on the admin panel, around the GitOps process, the pusher will be stuck if `--fail-on-manual-edits` is set, as expected. To recover from this, there are 2 options: 1. revert the admin panel changes to get back in sync with the code 2. check in the manual edits to code The former will work well, since previous and local ETags will match control ETag again. The latter will still fail, since local and control ETags match, but previous does not. For this situation, check the local ETag against control first and ignore previous when things are already in sync.

This is only useful if the etag cache is persistent or otherwise reliable. This flag should not be used in ephemeral CI workers that won't persist the cache.

Jordan Whited	f0230ce0b5	go.mod,net/tstun,wgengine/netstack: implement gVisor TCP GRO for Linux (#12921 ) This commit implements TCP GRO for packets being written to gVisor on Linux. Windows support will follow later. The wireguard-go dependency is updated in order to make use of newly exported IP checksum functions. gVisor is updated in order to make use of newly exported stack.PacketBuffer GRO logic. TCP throughput towards gVisor, i.e. TUN write direction, is dramatically improved as a result of this commit. Benchmarks show substantial improvement, sometimes as high as 2x. High bandwidth-delay product paths remain receive window limited, bottlenecked by gVisor's default TCP receive socket buffer size. This will be addressed in a follow-on commit. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them. The first result is from commit `57856fc` without TCP GRO. Starting Test: protocol: TCP, 1 streams, 131072 byte blocks - - - - - - - - - - - - - - - - - - - - - - - - - Test Complete.

Jordan Whited	7bc2ddaedc	go.mod,net/tstun,wgengine/netstack: implement gVisor TCP GSO for Linux (#12869 ) This commit implements TCP GSO for packets being read from gVisor on Linux. Windows support will follow later. The wireguard-go dependency is updated in order to make use of newly exported GSO logic from its tun package. A new gVisor stack.LinkEndpoint implementation has been established (linkEndpoint) that is loosely modeled after its predecessor (channel.Endpoint). This new implementation supports GSO of monster TCP segments up to 64K in size, whereas channel.Endpoint only supports up to 32K. linkEndpoint will also be required for GRO, which will be implemented in a follow-on commit. TCP throughput from gVisor, i.e. TUN read direction, is dramatically improved as a result of this commit. Benchmarks show substantial improvement through a wide range of RTT and loss conditions, sometimes as high as 5x. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them.

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.

Jordan Whited	0d6e71df70	cmd/stunstamp: add explicit metric to track timeout events (#12564 ) Timeouts could already be identified as NaN values on stunstamp_derp_stun_rtt_ns, but we can't use NaN effectively with promql to visualize them. So, this commit adds a timeouts metric that we can use with rate/delta/etc promql functions. Updates tailscale/corp#20689 Signed-off-by: Jordan Whited <jordan@tailscale.com>	5 months ago

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

Tom Proctor	3099323976	cmd/k8s-operator,k8s-operator,go.{mod,sum}: publish proxy status condition for annotated services (#12463 ) 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.
