60daa2adb8 all: fix golangci-lint errors
These erroneously blocked a recent PR, which I fixed by simply
re-running CI. But we might as well fix them anyway.
These are mostly `printf` to `print` and a couple of `!=` to `!Equal()`

1e2e319e7d util/slicesx: add MapKeys and MapValues from golang.org/x/exp/maps
Importing the ~deprecated golang.org/x/exp/maps as "xmaps" to not
shadow the std "maps" was getting ugly.

And using slices.Collect on an iterator is verbose & allocates more.

So copy (x)maps.Keys+Values into our slicesx package instead.

c43c5ca003 cmd/systray: properly set tooltip on different platforms

5a4148e7e8 cmd/systray: update state management and initialization
Move a number of global state vars into the Menu struct, keeping things
better encapsulated. The systray package still relies on its own global
state, so only a single Menu instance can run at a time.

Move a lot of the initialization logic out of onReady, in particular
fetching the latest tailscale state. Instead, populate the state before
calling systray.Run, which fixes a timing issue in GNOME (#14477).

This change also creates a separate bgContext for actions not tied menu
item clicks. Because we have to rebuild the entire menu regularly, we
cancel that context as needed, which can cancel subsequent updateState
calls.

Also exit cleanly on SIGINT and SIGTERM.

aa04f61d5e net/netcheck: adjust HTTPS latency check to connection time and avoid data race
The go-httpstat package has a data race when used with connections that
are performing happy-eyeballs connection setups as we are in the DERP
client. There is a long-stale PR upstream to address this, however
revisiting the purpose of this code suggests we don't really need
httpstat here.

The code populates a latency table that may be used to compare to STUN
latency, which is a lightweight RTT check. Switching out the reported
timing here to simply the request HTTP request RTT avoids the
problematic package.

06a82f416f cmd,{get-authkey,tailscale}: remove unnecessary scope qualifier from OAuth clients
OAuth clients that were used to generate an auth_key previously
specified the scope 'device'. 'device' is not an actual scope,
the real scope is 'devices'. The resulting OAuth token ended up
including all scopes from the specified OAuth client, so the code
was able to successfully create auth_keys.

It's better not to hardcode a scope here anyway, so that we have
the flexibility of changing which scope(s) are used in the future
without having to update old clients.

Since the qualifier never actually did anything, this commit simply
removes it.

cmd/k8s-operator: avoid port collision with metrics endpoint (#14185)
When the operator enables metrics on a proxy, it uses the port 9001,
and in the near future it will start using 9002 for the debug endpoint
as well. Make sure we don't choose ports from a range that includes
9001 so that we never clash. Setting TS_SOCKS5_SERVER, TS_HEALTHCHECK_ADDR_PORT,
TS_OUTBOUND_HTTP_PROXY_LISTEN, and PORT could also open arbitrary ports,
so we will need to document that users should not choose ports from the
10000-11000 range for those settings.

cmd/k8s-operator,docs/k8s: run tun mode proxies in privileged containers (#14262)
We were previously relying on unintended behaviour by runc where
all containers where by default given read/write/mknod permissions
for tun devices.
This behaviour was removed in https://github.com/opencontainers/runc/pull/3468
and released in runc 1.2.
Containerd container runtime, used by Docker and majority of Kubernetes distributions
bumped runc to 1.2 in 1.7.24 https://github.com/containerd/containerd/releases/tag/v1.7.24
thus breaking our reference tun mode Tailscale Kubernetes manifests and Kubernetes
operator proxies.

This PR changes the all Kubernetes container configs that run Tailscale in tun mode
to privileged. This should not be a breaking change because all these containers would
run in a Pod that already has a privileged init container.

cmd/containerboot: serve health on local endpoint (#14246)
* cmd/containerboot: serve health on local endpoint

We introduced stable (user) metrics in #14035, and `TS_LOCAL_ADDR_PORT`
with it. Rather than requiring users to specify a new addr/port
combination for each new local endpoint they want the container to
serve, this combines the health check endpoint onto the local addr/port
used by metrics if `TS_ENABLE_HEALTH_CHECK` is used instead of
`TS_HEALTHCHECK_ADDR_PORT`.

`TS_LOCAL_ADDR_PORT` now defaults to binding to all interfaces on 9002
so that it works more seamlessly and with less configuration in
environments other than Kubernetes, where the operator always overrides
the default anyway. In particular, listening on localhost would not be
accessible from outside the container, and many scripted container
environments do not know the IP address of the container before it's
started. Listening on all interfaces allows users to just set one env
var (`TS_ENABLE_METRICS` or `TS_ENABLE_HEALTH_CHECK`) to get a fully
functioning local endpoint they can query from outside the container.

50bf32a0ba cmd/tailscaled: flush DNS if FlushDNSOnSessionUnlock is true upon receiving a session change notification
In this PR, we move the syspolicy.FlushDNSOnSessionUnlock check from service startup
to when a session change notification is received. This ensures that the most recent policy
setting value is used if it has changed since the service started.

We also plan to handle session change notifications for unrelated reasons
and need to decouple notification subscriptions from DNS anyway.

cmd/{containerboot,k8s-operator},k8s-operator: new options to expose user metrics (#14035)
containerboot:

Adds 3 new environment variables for containerboot, `TS_LOCAL_ADDR_PORT` (default
`"${POD_IP}:9002"`), `TS_METRICS_ENABLED` (default `false`), and `TS_DEBUG_ADDR_PORT`
(default `""`), to configure metrics and debug endpoints. In a follow-up PR, the
health check endpoint will be updated to use the `TS_LOCAL_ADDR_PORT` if
`TS_HEALTHCHECK_ADDR_PORT` hasn't been set.

Users previously only had access to internal debug metrics (which are unstable
and not recommended) via passing the `--debug` flag to tailscaled, but can now
set `TS_METRICS_ENABLED=true` to expose the stable metrics documented at
https://tailscale.com/kb/1482/client-metrics at `/metrics` on the addr/port
specified by `TS_LOCAL_ADDR_PORT`.

Users can also now configure a debug endpoint more directly via the
`TS_DEBUG_ADDR_PORT` environment variable. This is not recommended for production
use, but exposes an internal set of debug metrics and pprof endpoints.

operator:

The `ProxyClass` CRD's `.spec.metrics.enable` field now enables serving the
stable user metrics documented at https://tailscale.com/kb/1482/client-metrics
at `/metrics` on the same "metrics" container port that debug metrics were
previously served on. To smooth the transition for anyone relying on the way the
operator previously consumed this field, we also _temporarily_ serve tailscaled's
internal debug metrics on the same `/debug/metrics` path as before, until 1.82.0
when debug metrics will be turned off by default even if `.spec.metrics.enable`
is set. At that point, anyone who wishes to continue using the internal debug
metrics (not recommended) will need to set the new `ProxyClass` field
`.spec.statefulSet.pod.tailscaleContainer.debug.enable`.

Users who wish to opt out of the transitional behaviour, where enabling
`.spec.metrics.enable` also enables debug metrics, can set
`.spec.statefulSet.pod.tailscaleContainer.debug.enable` to false (recommended).

Separately but related, the operator will no longer specify a host port for the
"metrics" container port definition. This caused scheduling conflicts when k8s
needs to schedule more than one proxy per node, and was not necessary for allowing
the pod's port to be exposed to prometheus scrapers.
