Brad Fitzpatrick	8b23ba7d05	tstest/natlab/vnet: add qemu + Virtualization.framework protocol tests ... To test how virtual machines connect to the natlab vnet code.

Brad Fitzpatrick	ff1d0aa027	tstest/natlab/vnet: start adding tests ... And refactor some of vnet.go for testability. The only behavioral change (with a new test) is that ethernet broadcasts no longer get sent back to the sender.

Brad Fitzpatrick	f99f970dc1	tstest/natlab/vnet: rename some things for clarity ... The bad naming (which had only been half updated with the IPv6 changes) tripped me up in the earlier change.

Brad Fitzpatrick	0157000cab	tstest/natlab: fix IPv6 tests, remove TODOs ... The reason they weren't working was because the cmd/tta agent in the guest was dialing out to the test and the vnet couldn't map its global unicast IPv6 address to a node as it was just using a map[netip.Addr]*node and blindly trusting the *node was populated. Instead, it was nil, so the agent connection fetching didn't work for its RoundTripper and the test could never drive the node. That map worked for IPv4 but for IPv6 we need to use the method that takes into account the node's IPv6 SLAAC address. Most call sites had been converted but I'd missed that one. Also clean up some debug, and prohibit nodes' link-local unicast addresses from dialing 2000::/3 directly for now. We can allow that to be configured opt-in later (some sort of IPv6 NAT mode. Whatever it's called.) That mode was working on accident, but was confusing: Linux would do source address selection from link local for the first few seconds and then after SLAAC and DAD, switch to using the global unicast source address. Be consistent for now and force it to use the global unicast. Updates #13038 Change-Id: I85e973aaa38b43c14611943ff45c7c825ee9200a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Brad Fitzpatrick	3904e4d175	cmd/tta, tstest/natlab/vnet: remove unneeded port 124 log hack, add log buffer ... The natlab Test Agent (tta) still had its old log streaming hack in place where it dialed out to anything on TCP port 124 and those logs were streamed to the host running the tests. But we'd since added gokrazy syslog streaming support, which made that redundant. So remove all the port 124 stuff. And then make sure we log to stderr so gokrazy logs it to syslog. Also, keep the first 1MB of logs in memory in tta too, exported via localhost:8034/logs for interactive debugging. That was very useful during debugging when I added IPv6 support.

Jonathan Nobels	8fad8c4b9b	tstest/tailmac: add customized macOS virtualization tooling (#13146) ... updates tailcale/corp#22371 Adds custom macOS vm tooling. See the README for the general gist, but this will spin up VMs with unixgram capable network interfaces listening to a named socket, and with a virtio socket device for host-guest communication. We can add other devices like consoles, serial, etc as needed. The whole things is buildable with a single make command, and everything is controllable via the command line using the TailMac utility. This should all be generally functional but takes a few shortcuts with error handling and the like. The virtio socket device support has not been tested and may require some refinement.

The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda chaotic and they both need to be redone/deleted (respectively), but this fixes some buggy behavior meanwhile. We were previously calling StartLoginInteractive (to start the controlclient's RegisterRequest) redundantly in some cases, causing test flakes depending on timing and up's weird state machine. We only need to call StartLoginInteractive in the client if Start itself doesn't. But Start doesn't tell us that. So cheat a bit and a put the information about whether there's a current NodeKey in the ipn.Status. It used to be accessible over LocalAPI via GetPrefs as a private key but we removed that for security. But a bool is fine.

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.

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491) ... Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

Irbe Krumina	1a08ea5990	cmd/k8s-operator: operator can create subnetrouter (#9505) ... * k8s-operator,cmd/k8s-operator,Makefile,scripts,.github/workflows: add Connector kube CRD. Connector CRD allows users to configure the Tailscale Kubernetes operator to deploy a subnet router to expose cluster CIDRs or other CIDRs available from within the cluster to their tailnet. Also adds various CRD related machinery to generate CRD YAML, deep copy implementations etc. Engineers will now have to run 'make kube-generate-all` after changing kube files to ensure that all generated files are up to date. * cmd/k8s-operator,k8s-operator: reconcile Connector resources Reconcile Connector resources, create/delete subnetrouter resources in response to changes to Connector(s). Connector reconciler will not be started unless ENABLE_CONNECTOR env var is set to true. This means that users who don't want to use the alpha Connector custom resource don't have to install the Connector CRD to their cluster. For users who do want to use it the flow is: - install the CRD - install the operator (via Helm chart or using static manifests). For Helm users set .values.enableConnector to true, for static manifest users, set ENABLE_CONNECTOR to true in the static manifest.

Sonia Appasamy	89953b015b	ipn/ipnlocal,client/web: add web client to tailscaled ... Allows for serving the web interface from tailscaled, with the ability to start and stop the server via localapi endpoints (/web/start and /web/stop). This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.

Tom DNetto	3df305b764	tsnet: enable use-cases with non-native IPs by setting ns.ProcessSubnets ...

In addition to supporting such termination, this change will also enable exit nodes and subnet routers when running in userspace mode. DO NOT MERGE until 1.52 is cut.
