cmd/k8s-operator,k8s-operator: use default ProxyClass if set for ProxyGroup (#13720)
The default ProxyClass can be set via helm chart or env var, and applies
to all proxies that do not otherwise have an explicit ProxyClass set.
This ensures proxies created by the new ProxyGroup CRD are consistent
with the behaviour of existing proxies

Nearby but unrelated changes:

* Fix up double error logs (controller runtime logs returned errors)
* Fix a couple of variable names

cmd/{containerboot,k8s-operator},k8s-operator,kube: add ProxyGroup controller (#13684)
Implements the controller for the new ProxyGroup CRD, designed for
running proxies in a high availability configuration. Each proxy gets
its own config and state Secret, and its own tailscale node ID.

We are currently mounting all of the config secrets into the container,
but will stop mounting them and instead read them directly from the kube
API once #13578 is implemented.

cmd/{k8s-operator,containerboot},k8s-operator,kube: reconcile ExternalName Services for ProxyGroup (#13635)
Adds a new reconciler that reconciles ExternalName Services that define a
tailnet target that should be exposed to cluster workloads on a ProxyGroup's
proxies.
The reconciler ensures that for each such service, the config mounted to
the proxies is updated with the tailnet target definition and that
and EndpointSlice and ClusterIP Service are created for the service.

Adds a new reconciler that ensures that as proxy Pods become ready to route
traffic to a tailnet target, the EndpointSlice for the target is updated
with the Pods' endpoints.

cmd/containerboot,util/linuxfw: create a SNAT rule for dst/src only once, clean up if needed (#13658)
The AddSNATRuleForDst rule was adding a new rule each time it was called including:
- if a rule already existed
- if a rule matching the destination, but with different desired source already existed

This was causing issues especially for the in-progress egress HA proxies work,
where the rules are now refreshed more frequently, so more redundant rules
were being created.

This change:
- only creates the rule if it doesn't already exist
- if a rule for the same dst, but different source is found, delete it
- also ensures that egress proxies refresh firewall rules
if the node's tailnet IP changes

cmd/containerboot,kube,util/linuxfw: configure kube egress proxies to route to 1+ tailnet targets (#13531)
* cmd/containerboot,kube,util/linuxfw: configure kube egress proxies to route to 1+ tailnet targets

This commit is first part of the work to allow running multiple
replicas of the Kubernetes operator egress proxies per tailnet service +
to allow exposing multiple tailnet services via each proxy replica.

This expands the existing iptables/nftables-based proxy configuration
mechanism.

A proxy can now be configured to route to one or more tailnet targets
via a (mounted) config file that, for each tailnet target, specifies:
- the target's tailnet IP or FQDN
- mappings of container ports to which cluster workloads will send traffic to
tailnet target ports where the traffic should be forwarded.

Example configfile contents:
{
  "some-svc": {"tailnetTarget":{"fqdn":"foo.tailnetxyz.ts.net","ports"{"tcp:4006:80":{"protocol":"tcp","matchPort":4006,"targetPort":80},"tcp:4007:443":{"protocol":"tcp","matchPort":4007,"targetPort":443}}}}
}

A proxy that is configured with this config file will configure firewall rules
to route cluster traffic to the tailnet targets. It will then watch the config file
for updates as well as monitor relevant netmap updates and reconfigure firewall
as needed.

This adds a bunch of new iptables/nftables functionality to make it easier to dynamically update
the firewall rules without needing to restart the proxy Pod as well as to make
it easier to debug/understand the rules:

- for iptables, each portmapping is a DNAT rule with a comment pointing
at the 'service',i.e:

-A PREROUTING ! -i tailscale0 -p tcp -m tcp --dport 4006 -m comment --comment "some-svc:tcp:4006 -> tcp:80" -j DNAT --to-destination 100.64.1.18:80
Additionally there is a SNAT rule for each tailnet target, to mask the source address.

- for nftables, a separate prerouting chain is created for each tailnet target
and all the portmapping rules are placed in that chain. This makes it easier
to look up rules and delete services when no longer needed.
(nftables allows hooking a custom chain to a prerouting hook, so no extra work
is needed to ensure that the rules in the service chains are evaluated).

The next steps will be to get the Kubernetes Operator to generate
the configfile and ensure it is mounted to the relevant proxy nodes.

cmd/k8s-operator: remove auth key once proxy has logged in (#13612)
The operator creates a non-reusable auth key for each of
the cluster proxies that it creates and puts in the tailscaled
configfile mounted to the proxies.
The proxies are always tagged, and their state is persisted
in a Kubernetes Secret, so their node keys are expected to never
be regenerated, so that they don't need to re-auth.

Some tailnet configurations however have seen issues where the auth
keys being left in the tailscaled configfile cause the proxies
to end up in unauthorized state after a restart at a later point
in time.
Currently, we have not found a way to reproduce this issue,
however this commit removes the auth key from the config once
the proxy can be assumed to have logged in.

If an existing, logged-in proxy is upgraded to this version,
its redundant auth key will be removed from the conffile.

If an existing, logged-in proxy is downgraded from this version
to a previous version, it will work as before without re-issuing key
as the previous code did not enforce that a key must be present.

cmd/k8s-operator,k8s-operator: add ProxyGroup CRD (#13591)
The ProxyGroup CRD specifies a set of N pods which will each be a
tailnet device, and will have M different ingress or egress services
mapped onto them. It is the mechanism for specifying how highly
available proxies need to be. This commit only adds the definition, no
controller loop, and so it is not currently functional.

This commit also splits out TailnetDevice and RecorderTailnetDevice
into separate structs because the URL field is specific to recorders,
but we want a more generic struct for use in the ProxyGroup status field.

cli: implement `tailscale dns status` (#13353)
Updates tailscale/tailscale#13326

This PR begins implementing a `tailscale dns` command group in the Tailscale CLI. It provides an initial implementation of `tailscale dns status` which dumps the state of the internal DNS forwarder.

Two new endpoints were added in LocalAPI to support the CLI functionality:

- `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy)
- `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information)

My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

cmd/k8s-operator,k8s-operator/sessionrecording: ensure recording header contains terminal size for terminal sessions (#12965)
* cmd/k8s-operator,k8s-operator/sessonrecording: ensure CastHeader contains terminal size

For tsrecorder to be able to play session recordings, the recording's
CastHeader must have '.Width' and '.Height' fields set to non-zero.
Kubectl (or whoever is the client that initiates the 'kubectl exec'
session recording) sends the terminal dimensions in a resize message that
the API server proxy can intercept, however that races with the first server
message that we need to record.
This PR ensures we wait for the terminal dimensions to be processed from
the first resize message before any other data is sent, so that for all
sessions with terminal attached, the header of the session recording
contains the terminal dimensions and the recording can be played by tsrecorder.

Nick Khyl 961ee321e8 ipn/{ipnauth,ipnlocal,ipnserver,localapi}: start baby step toward moving access checks from the localapi.Handler to the LocalBackend
Currently, we use PermitRead/PermitWrite/PermitCert permission flags to determine which operations are allowed for a LocalAPI client.
These checks are performed when localapi.Handler handles a request. Additionally, certain operations (e.g., changing the serve config)
requires the connected user to be a local admin. This approach is inherently racey and is subject to TOCTOU issues.
We consider it to be more critical on Windows environments, which are inherently multi-user, and therefore we prevent more than one
OS user from connecting and utilizing the LocalBackend at the same time. However, the same type of issues is also applicable to other
platforms when switching between profiles that have different OperatorUser values in ipn.Prefs.

We'd like to allow more than one Windows user to connect, but limit what they can see and do based on their access rights on the device
(e.g., an local admin or not) and to the currently active LoginProfile (e.g., owner/operator or not), while preventing TOCTOU issues on Windows
and other platforms. Therefore, we'd like to pass an actor from the LocalAPI to the LocalBackend to represent the user performing the operation.
The LocalBackend, or the profileManager down the line, will then check the actor's access rights to perform a given operation on the device
and against the current (and/or the target) profile.

This PR does not change the current permission model in any way, but it introduces the concept of an actor and includes some preparatory
work to pass it around. Temporarily, the ipnauth.Actor interface has methods like IsLocalSystem and IsLocalAdmin, which are only relevant
to the current permission model. It also lacks methods that will actually be used in the new model. We'll be adding these gradually in the next
PRs and removing the deprecated methods and the Permit* flags at the end of the transition.

these type assertions no longer work as expected unless the new behavior is disabled

In this PR, we add codegen.NamedTypeOf(t types.Type), which functions like t.(*types.Named)
but also unrolls type aliases. We then use it in place of type assertions in the cmd/cloner and
cmd/viewer packages where appropriate.

We also update type switches to include *types.Alias alongside *types.Named in relevant cases,
remove *types.Struct cases when switching on types.Type.Underlying and update the tests
with more cases where type aliases can be used.

In this PR, we update codegen.LookupMethod to perform method lookup on the right-hand side of the alias declaration
and clearly switch on the supported type nodes types. We also improve support for various edge cases, such as when an alias
is used as a type parameter constraint, and add tests for the LookupMethod function.

place where it dialed out to anything on TCP port 124 and those logs

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. (which is coming in future
PRs)

This uses fyne.io/systray (a fork of github.com/getlantern/systray)

This results in a pretty broad support for modern desktop environments.

This initial commit lacks a number of features like profile switching,
