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.

We add a policy definition for the AllowedSuggestedExitNodes syspolicy setting, allowing admins
to configure a list of exit node IDs to be used as a pool for automatic suggested exit node selection.
We update definitions for policy settings configurable on both a per-user and per-machine basis,
such as UI customizations, to specify class="Both".
Lastly, we update the help text for existing policy definitions to include a link to the KB article
as the last line instead of in the first paragraph.

This is a follow-up to #14112 where our internal kube client was updated
to allow it to emit Events - this updates our sample kube manifests
and tsrecorder manifest templates so they can benefit from this functionality.

In https://github.com/tailscale/tailscale/pull/11363
I changed the subnet router manifest to run in tun
mode (for performance reasons), but did not
change the security context to give it net_admin,
which is required to for the tailscale socket.

Update docs for static Tailscale deployments on kube
to always use firewall mode autodection when in non-userspace.
Also add a note about running multiple replicas and a few suggestions how folks could do that.

The script depends on a sufficiently recent start-stop-daemon as to
provide the `-m` and `--remove-pidfile` flags.

Instead of calling kubectl directly in k8s Makefile, write the yaml to
stdout so it can be reviewed/edited/etc before manually applying with
kubectl.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.
Updates #6865
Signed-off-by: Will Norris <will@tailscale.com>
This implements the same functionality as the former run.sh, but in Go
and with a little better awareness of tailscaled's lifecycle.
Also adds TS_AUTH_ONCE, which fixes the unfortunate behavior run.sh had
where it would unconditionally try to reauth every time if you gave it
an authkey, rather than try to use it only if auth is actually needed.
This makes it a bit nicer to deploy these containers in automation, since
you don't have to run the container once, then go and edit its definition
to remove authkeys.

It was previously using jobcontrol to achieve this, but that apparently
doesn't work when there is no tty. This makes it so that it directly
handles SIGINT and SIGTERM and passes it on to tailscaled. I tested this
works on a Digital Ocean K8s cluster.

This has the benefit of propagating SIGINT to tailscaled, which in turn
can react to the event and logout in case of an ephemeral node.
Also fix missing run.sh in Dockerfile.
