net/interfaces: handle iOS network transitions (#10680)
Updates #8022
Updates #6075

On iOS, we currently rely on delegated interface information to figure out the default route interface.  The NetworkExtension framework in iOS seems to set the delegate interface only once, upon the *creation* of the VPN tunnel. If a network transition (e.g. from Wi-Fi to Cellular) happens while the tunnel is connected, it will be ignored and we will still try to set Wi-Fi as the default route because the delegated interface is not getting updated as connectivity transitions.

Here we work around this on the Swift side with a NWPathMonitor instance that observes the interface name of the first currently satisfied network path. Our Swift code will call into `UpdateLastKnownDefaultRouteInterface`, so we can rely on that when it is set.

If for any reason the Swift machinery didn't work and we don't get any updates, here we also have some fallback logic: we try finding a hardcoded Wi-Fi interface called en0. If en0 is down, we fall back to cellular (pdp_ip0) as a last resort. This doesn't handle all edge cases like USB-Ethernet adapters or multiple Ethernet interfaces, but it is good enough to ensure connectivity isn't broken.

I tested this on iPhones and iPads running iOS 17.1 and it appears to work. Switching between different cellular plans on a dual SIM configuration also works (the interface name remains pdp_ip0).

cmd/containerboot: ensure that subnet routes can be unset. (#10734)
A Tailnet node can be told to stop advertise subnets by passing
an empty string to --advertise-routes flag.
Respect an explicitly passed empty value to TS_ROUTES env var
so that users have a way to stop containerboot acting as a subnet
router without recreating it.
Distinguish between TS_ROUTES being unset and empty.

Adrian Dewhurst 3d57c885bf logpolicy: use syspolicy to override LogTarget
Previously, for Windows clients only, a registry value named LogTarget
could override the log server, but only if the environment variable was
unset.

To allow administrators to enforce using a particular log server, switch
this to make the registry value take precedence over the environment
variable, and switch to the newer syspolicy.GetString so that the log
target can be specified by a GPO more easily.

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 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.

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.

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 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.
