cmd/k8s-operator,k8s-operator: allow the operator to deploy exit nodes via Connector custom resource (#10724)
cmd/k8s-operator/deploy/crds,k8s-operator/apis/v1alpha1: allow to define an exit node via Connector CR.

Make it possible to define an exit node to be deployed to a Kubernetes cluster
via Connector Custom resource.

Also changes to Connector API so that one Connector corresponds
to one Tailnet node that can be either a subnet router or an exit
node or both.

The Kubernetes operator parses Connector custom resource and,
if .spec.isExitNode is set, configures that Tailscale node deployed
for that connector as an exit node.

cmd/containerboot: add EXPERIMENTAL_TS_CONFIGFILE_PATH env var to allow passing tailscaled config in a file (#10759)
* cmd/containerboot: optionally configure tailscaled with a configfile.

If EXPERIMENTAL_TS_CONFIGFILE_PATH env var is set,
only run tailscaled with the provided config file.
Do not run 'tailscale up' or 'tailscale set'.

* cmd/containerboot: store containerboot accept_dns val in bool pointer

So that we can distinguish between the value being set to
false explicitly bs being unset.

This tripped me up when I was testing something and wrote:

In netstack mode, when an error occurred we were getting a non-nil error

return a nil interface value.

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.

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.

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.

This fixes a bug where passing a track name in `args.Version` would keep

7bdea283bd cmd/containerboot: symlink TS_SOCKET to socket expected by CLI
`tailscaled` and `tailscale` expect the socket to be at
`/var/run/tailscale/tailscaled.sock`, however containerboot
would set up the socket at `/tmp/tailscaled.sock`. This leads to a
poor UX when users try to use any `tailscale` command as they
have to prefix everything with `--socket /tmp/tailscaled.sock`.

To improve the UX, this adds a symlink to
`/var/run/tailscale/tailscaled.sock` to point to `/tmp/tailscaled.sock`.

This approach has two benefits, 1 users are able to continue to use
existing scripts without this being a breaking change. 2. users are
able to use the `tailscale` CLI without having to add the `--socket` flag.

ipn,cmd/tailscale/cli: support hierarchical MaskedPrefs (#10507)
Some fields if `ipn.Prefs` are structs. `ipn.MaskedPrefs` has a single
level of boolean `*Set` flags, which doesn't map well to nested structs
within `ipn.Prefs`.

Change `MaskedPrefs` and `ApplyEdits` to support `FooSet` struct fields
that map to a nested struct of `ipn.Prefs` like `AutoUpdates`. Each
struct field in `MaskedPrefs` is just a bundle of more `Set` bool fields
or other structs. This allows you to have a `Set` flag for any
arbitrarily-nested field of `ipn.Prefs`.

Also, make `ApplyEdits` match fields between `Prefs` and `MaskedPrefs`
by name instead of order, to make it a bit less finicky. It's probably
slower but `ipn.ApplyEdits` should not be in any hot path.

As a result, `AutoUpdate.Check` and `AutoUpdate.Apply` fields don't
clobber each other when set individually.

b819f66eb1 tsweb: propagate RequestID via context and entire request
The recent addition of RequestID was only populated if the
HTTP Request had returned an error. This meant that the underlying
handler has no access to this request id and any logs it may have
emitted were impossible to correlate to that request id. Therefore,
this PR adds a middleware to generate request ids and pass them
through the request context. The tsweb.StdHandler automatically
populates this request id if the middleware is being used. Finally,
inner handlers can use the context to retrieve that same request id
and use it so that all logs and events can be correlated.

2dc0645368 ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profile
This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled
clients can use this value to disambiguate fast user switching from one tailnet
to another that are under the same exact login. We will also try to backfill
this information during backend starts and profile switches so that users don't
have to re-authenticate their profile. The first client to use this new
information is the CLI in 'tailscale switch -list' which now uses text/tabwriter
to display the ID, Tailnet, and Account. Since account names are ambiguous, we
allow the user to pass 'tailscale switch ID' to specify the exact tailnet they
want to switch to.

855f79fad7 cmd/tailscaled, util/winutil: changes to process and token APIs in winutil
This PR changes the internal getTokenInfo function to use generics.
I also removed our own implementations for obtaining a token's user
and primary group in favour of calling the ones now available in
x/sys/windows.

Furthermore, I added two new functions for working with tokens, logon
session IDs, and Terminal Services / RDP session IDs.

I modified our privilege enabling code to allow enabling of multiple
privileges via one single function call.

Finally, I added the ProcessImageName function and updated the code in
tailscaled_windows.go to use that instead of directly calling the
underlying API.

All of these changes will be utilized by subsequent PRs pertaining to
this issue.

9b537f7c97 ipn: remove the preview-webclient node capability
Now that 1.54 has released, and the new web client will be included in
1.56, we can remove the need for the node capability. This means that
all 1.55 unstable builds, and then eventually the 1.56 build, will work
without setting the node capability.

The web client still requires the "webclient" user pref, so this does
NOT mean that the web client will be on by default for all devices.

Unfortunately there are other products out there that, partying like it's

look there first, we end up loading that old version.

We can fix this by preloading wintun using a fully-qualified path. When
wintun-go then loads wintun, the dynamic linker will hand it the module
that was previously loaded by us.

3d7fb6c21d derp/derphttp: fix race in mesh watcher
The derphttp client automatically reconnects upon failure.

RunWatchConnectionLoop called derphttp.Client.WatchConnectionChanges
once, but that wrapper method called the underlying
derp.Client.WatchConnectionChanges exactly once on derphttp.Client's
currently active connection. If there's a failure, we need to re-subscribe
upon all reconnections.

This removes the derphttp.Client.WatchConnectionChanges method, which
was basically impossible to use correctly, and changes it to be a
boolean field on derphttp.Client alongside MeshKey and IsProber. Then
it moves the call to the underlying derp.Client.WatchConnectionChanges
to derphttp's client connection code, so it's resubscribed on any
reconnect.

Some paranoia is then added to make sure people hold the API right,
not calling derphttp.Client.RunWatchConnectionLoop on an
already-started Client without having set the bool to true. (But still
auto-setting it to true if that's the first method that's been called
on that derphttp.Client, as is commonly the case, and prevents
existing code from breaking)

This will be used to run the new full management web client,

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

95671b71a6 ipn, safesocket: use Windows token in LocalAPI
On Windows, the idiomatic way to check access on a named pipe is for
the server to impersonate the client on its current OS thread, perform
access checks using the client's access token, and then revert the OS
thread's access token back to its true self.

The access token is a better representation of the client's rights than just
a username/userid check, as it represents the client's effective rights
at connection time, which might differ from their normal rights.

This patch updates safesocket to do the aforementioned impersonation,
extract the token handle, and then revert the impersonation. We retain
the token handle for the remaining duration of the connection (the token
continues to be valid even after we have reverted back to self).

Since the token is a property of the connection, I changed ipnauth to wrap
the concrete net.Conn to include the token. I then plumbed that change
through ipnlocal, ipnserver, and localapi as necessary.

I also added a PermitLocalAdmin flag to the localapi Handler which I intend
to use for controlling access to a few new localapi endpoints intended
for configuring auto-update.
