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. The first result is from commit `57856fc` without TCP GSO. Starting Test: protocol: TCP, 1 streams, 131072 byte blocks - - - - - - - - - - - - - - - - - - - - - - - - - Test Complete.

Andrew Lytvynov	e7bf6e716b	cmd/tailscale: add --min-validity flag to the cert command (#12822 ) Some users run "tailscale cert" in a cron job to renew their certificates on disk. The time until the next cron job run may be long enough for the old cert to expire with our default heristics. Add a `--min-validity` flag which ensures that the returned cert is valid for at least the provided duration (unless it's longer than the cert lifetime set by Let's Encrypt).

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.

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>	3 months ago
