Irbe Krumina	a15ff1bade	cmd/k8s-operator,k8s-operator/sessionrecording: support recording kubectl exec sessions over WebSockets (#12947 ) cmd/k8s-operator,k8s-operator/sessionrecording: support recording WebSocket sessions Kubernetes currently supports two streaming protocols, SPDY and WebSockets. WebSockets are replacing SPDY, see https://github.com/kubernetes/enhancements/issues/4006. We were currently only supporting SPDY, erroring out if session was not SPDY and relying on the kube's built-in SPDY fallback. This PR: - adds support for parsing contents of 'kubectl exec' sessions streamed over WebSockets - adds logic to distinguish 'kubectl exec' requests for a SPDY/WebSockets sessions and call the relevant handler Updates tailscale/corp#19821 Signed-off-by: Irbe Krumina <irbe@tailscale.com> Co-authored-by: Tom Proctor <tomhjp@users.noreply.github.com>	1 month ago

Irbe Krumina	b9f42814b5	cmd/containerboot: optionally serve health check endpoint (#12899 ) Add functionality to optionally serve a health check endpoint (off by default). Users can enable health check endpoint by setting TS_HEALTHCHECK_ADDR_PORT to [<addr>]:<port>. Containerboot will then serve an unauthenticatd HTTP health check at /healthz at that address. The health check returns 200 OK if the node has at least one tailnet IP address, else returns 503. Updates tailscale/tailscale#12898 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	1 month ago

In fact, there can be multiple, for example, in dual-stack clusters, but also in other cases this is valid (as per kube docs).

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.

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.
