Nick Khyl	c9836b454d	net/netmon: fix goroutine leak in winMon if the monitor is never started When the portable Monitor creates a winMon via newOSMon, we register address and route change callbacks with Windows. Once a callback is hit, it starts a goroutine that attempts to send the event into messagec and returns. The newly started goroutine then blocks until it can send to the channel. However, if the monitor is never started and winMon.Receive is never called, the goroutines remain indefinitely blocked, leading to goroutine leaks and significant memory consumption in the tailscaled service process on Windows. Unlike the tailscaled subprocess, the service process creates but never starts a Monitor. This PR adds a check within the callbacks to confirm the monitor's active status, and exits immediately if the monitor hasn't started.

Andrew Lytvynov	2e956713de	safesocket: remove ConnectionStrategy (#10662 ) This type seems to be a migration shim for TCP tailscaled sockets (instead of unix/windows pipes). The `port` field was never set, so it was effectively used as a string (`path` field). Remove the whole type and simplify call sites to pass the socket path directly to `safesocket.Connect`.

Andrew Dunham	01286af82b	net/interfaces: better handle multiple interfaces in LikelyHomeRouterIP Currently, we get the "likely home router" gateway IP and then iterate through all IPs for all interfaces trying to match IPs to determine the source IP. However, on many platforms we know what interface the gateway is through, and thus we don't need to iterate through all interfaces checking IPs. Instead, use the IP address of the associated interface. This better handles the case where we have multiple interfaces on a system all connected to the same gateway, and where the first interface that we visit (as iterated by ForeachInterfaceAddress) isn't also the default internet route.

Sonia Appasamy	c6a274611e	client/web: use Tailscale IP known by peer node Throughout the web UI, we present the tailscale addresses for the self node. In the case of the node being shared out with a user from another tailnet, the peer viewer may actually know the node by a different IP than the node knows itself as (Tailscale IPs can be configured as desired on a tailnet level). This change includes two fixes: 1. Present the self node's addresses in the frontend as the addresses the viewing node knows it as (i.e. the addresses the viewing node uses to access the web client). 2. We currently redirect the viewer to the Tailscale IPv4 address if viewing it by MagicDNS name, or any other name that maps to the Tailscale node. When doing this redirect, which is primarily added for DNS rebinding protection, we now check the address the peer knows this node as, and redirect to specifically that IP.

Jordan Whited	685b853763	wgengine/magicsock: fix handling of derp.PeerGoneMessage (#10589 ) The switch in Conn.runDerpReader() on the derp.ReceivedMessage type contained cases other than derp.ReceivedPacket that fell through to writing to c.derpRecvCh, which should only be reached for derp.ReceivedPacket. This can result in the last/previous derp.ReceivedPacket to be re-handled, effectively creating a duplicate packet. If the last derp.ReceivedPacket happens to be a disco.CallMeMaybe it may result in a disco ping scan towards the originating peer on the endpoints contained. The change in this commit moves the channel write on c.derpRecvCh and subsequent select awaiting the result into the derp.ReceivedMessage case, preventing it from being reached from any other case. Explicit continue statements are also added to non-derp.ReceivedPacket cases where they were missing, in order to signal intent to the reader.

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.

Andrew Dunham	727acf96a6	net/netcheck: use DERP frames as a signal for home region liveness This uses the fact that we've received a frame from a given DERP region within a certain time as a signal that the region is stil present (and thus can still be a node's PreferredDERP / home region) even if we don't get a STUN response from that region during a netcheck. This should help avoid DERP flaps that occur due to losing STUN probes while still having a valid and active TCP connection to the DERP server.

Andrew Dunham	bac4890467	net/portmapper: be smarter about selecting a UPnP device Previously, we would select the first WANIPConnection2 (and related) client from the root device, without any additional checks. However, some routers expose multiple UPnP devices in various states, and simply picking the first available one can result in attempting to perform a portmap with a device that isn't functional. Instead, mimic what the miniupnpc code does, and prefer devices that are (a) reporting as Connected, and (b) have a valid external IP address. For our use-case, we additionally prefer devices that have an external IP address that's a public address, to increase the likelihood that we can obtain a direct connection from peers. Finally, we split out fetching the root device (getUPnPRootDevice) from selecting the best service within that root device (selectBestService), and add some extensive tests for various UPnP server behaviours.

Will Norris	1b7d289fad	client/web: add debug card to details page Add a new "Debug" card at the bottom of the details page. It's maybe premature to add a separate card for this, since all it currently lists is whether the device is using TUN mode and (for Synology) the DSM version. But I think it may be helpful to add client connectivity data (like shown on admin console machine page) as well as a bug report button. Those can come soon after the 1.56 launch.
