cmd/k8s-nameserver: fix AAAA record query response (#12412)
Return empty response and NOERROR for AAAA record queries
for DNS names for which we have an A record.
This is to allow for callers that might be first sending an AAAA query and then,
if that does not return a response, follow with an A record query.
Previously we were returning NOTIMPL that caused some callers
to potentially not follow with an A record query or misbehave in different ways.

Also return NXDOMAIN for AAAA record queries for names
that we DO NOT have an A record for to ensure that the callers
do not follow up with an A record query.

Returning an empty response and NOERROR is the behaviour
that RFC 4074 recommends:

tailcfg,cmd/k8s-operator,kube: move Kubernetes cap to a location that can be shared with control (#12236)
This PR is in prep of adding logic to control to be able to parse
tailscale.com/cap/kubernetes grants in control:
- moves the type definition of PeerCapabilityKubernetes cap to a location
shared with control.
- update the Kubernetes cap rule definition with fields for granting
kubectl exec session recording capabilities.
- adds a convenience function to produce tailcfg.RawMessage from an
arbitrary cap rule and a test for it.

An example grant defined via ACLs:
"grants": [{
      "src": ["tag:eng"],
      "dst": ["tag:k8s-operator"],
      "app": {
        "tailscale.com/cap/kubernetes": [{
            "recorder": ["tag:my-recorder"]
	    “enforceRecorder”: true
        }],
      },
    }
]
This grant enforces `kubectl exec` sessions from tailnet clients,
matching `tag:eng` via API server proxy matching `tag:k8s-operator`
to be recorded and recording to be sent to a tsrecorder instance,
matching `tag:my-recorder`.

The type needs to be shared with control because we want
control to parse this cap and resolve tags to peer IPs.

Maisem Ali 0b1a8586eb cmd/natc: initial implementation of a NAT based connector
This adds a new prototype `cmd/natc` which can be used
to expose a services/domains to the tailnet.

It requires the user to specify a set of IPv4 prefixes
from the CGNAT range. It advertises these as normal subnet
routes. It listens for DNS on the first IP of the first range
provided to it.

When it gets a DNS query it allocates an IP for that domain
from the v4 range. Subsequent connections to the assigned IP
are then tcp proxied to the domain.

It is marked as a WIP prototype and requires the use of the
`TAILSCALE_USE_WIP_CODE` env var.

James Tucker 8d1249550a net/netcheck,wgengine/magicsock: add potential workaround for Palo Alto DIPP misbehavior
Palo Alto firewalls have a typically hard NAT, but also have a mode
called Persistent DIPP that is supposed to provide consistent port
mapping suitable for STUN resolution of public ports. Persistent DIPP
works initially on most Palo Alto firewalls, but some models/software
versions have a bug which this works around.

The bug symptom presents as follows:

- STUN sessions resolve a consistent public IP:port to start with
- Much later netchecks report the same IP:Port for a subset of
  sessions, most often the users active DERP, and/or the port related
  to sustained traffic.
- The broader set of DERPs in a full netcheck will now consistently
  observe a new IP:Port.
- After this point of observation, new inbound connections will only
  succeed to the new IP:Port observed, and existing/old sessions will
  only work to the old binding.

In this patch we now advertise the lowest latency global endpoint
discovered as we always have, but in addition any global endpoints that
are observed more than once in a single netcheck report. This should
provide viable endpoints for potential connection establishment across
a NAT with this behavior.

On Apple platforms, exit nodes and subnet routers have been unable to relay pings from Tailscale devices to non-Tailscale devices due to sandbox restrictions imposed on our network extensions by Apple. The sandbox prevented the code in netstack.go from spawning the `ping` process which we were using.

Replace that exec call with logic to send an ICMP echo request directly, which appears to work in userspace, and not trigger a sandbox violation in the syslog.

Brad Fitzpatrick e968b0ecd7 cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more
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.

So then only call StartLoginInteractive if that bool is false and don't
do it in the WatchIPNBus loop.

Brad Fitzpatrick f3d2fd22ef cmd/tailscale/cli: don't start WatchIPNBus until after up's initial Start
The CLI "up" command is a historical mess, both on the CLI side and
the LocalBackend side. We're getting closer to cleaning it up, but in
the meantime it was again implicated in flaky tests.

In this case, the background goroutine running WatchIPNBus was very
occasionally running enough to get to its StartLoginInteractive call
before the original goroutine did its Start call. That meant
integration tests were very rarely but sometimes logging in with the
default control plane URL out on the internet
(controlplane.tailscale.com) instead of the localhost control server
for tests.

This also might've affected new Headscale etc users on initial "up".

Nick Khyl caa3d7594f ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial
We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP.
This is primarily necessary to properly dial internal DNS servers accessible
over Tailscale and subnet routes. However, to avoid issues when switching
between Wi-Fi and cellular, we need to ensure that we don't retain connections
to any external addresses on the old interface. Therefore, we need to determine
which dialer to use internally based on the configured routes.

and updates UserDial to use either the peer dialer or the system dialer,
depending on the network address and the configured routes.
