Maisem Ali 4899c2c1f4 cmd/containerboot: revert to using tailscale up
This partially reverts commits a61a9ab087
and 7538f38671 and fully reverts
4823a7e591.

The goal of that commit was to reapply known config whenever the
container restarts. However, that already happens when TS_AUTH_ONCE was
false (the default back then). So we only had to selectively reapply the
config if TS_AUTH_ONCE is true, this does exactly that.

This is a little sad that we have to revert to `tailscale up`, but it
fixes the backwards incompatibility problem.

Maisem Ali fbfee6a8c0 cmd/containerboot: use linuxfw.NetfilterRunner
This migrates containerboot to reuse the NetfilterRunner used
by tailscaled instead of manipulating iptables rule itself.
This has the added advantage of now working with nftables and
we can potentially drop the `iptables` command from the container
image in the future.

Updates #9310

Denton Gentry 4823a7e591 cmd/containerboot: set TS_AUTH_ONCE default to true.
1.50.0 switched containerboot from using `tailscale up`
to `tailscale login`. A side-effect is that a re-usable
authkey is now re-applied on every boot by `tailscale login`,
where `tailscale up` would ignore an authkey if already
authenticated.

Though this looks like it is changing the default, in reality
it is setting the default to match what 1.48 and all
prior releases actually implemented.

James Tucker a82a74f2cf cmd/containerboot: avoid leaking bash scripts after test runs
The test was sending SIGKILL to containerboot, which results in no
signal propagation down to the bash script that is running as a child
process, thus it leaks.

Minor changes to the test daemon script, so that it cleans up the socket
that it creates on exit, and spawns fewer processes.

Fixes tailscale/corp#14833

Maisem Ali 4669e7f7d5 cmd/containerboot: add iptables based MSS clamping for ingress/egress proxies
In typical k8s setups, the MTU configured on the eth0 interfaces is typically 1500 which
results in packets being dropped when they make it to proxy pods as the tailscale0 interface
has a 1280 MTU.

As the primary use of this functionality is TCP, add iptables based MSS clamping to allow
connectivity.

Maisem Ali e1530cdfcc cmd/containerboot,kube: consolidate the two kube clients
We had two implemenetations of the kube client, merge them.

containerboot was also using a raw http.Transport, this also has
the side effect of making it use a http.Client

Will Norris 71029cea2d all: update copyright and license headers
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.

David Anderson af3127711a cmd/containerboot: allow disabling secret storage in k8s.
In some configurations, user explicitly do not want to store
tailscale state in k8s secrets, because doing that leads to
some annoying permission issues with sidecar containers.
With this change, TS_KUBE_SECRET="" and TS_STATE_DIR=/foo
will force storage to file when running in kubernetes.

Fixes #6704.

David Anderson 1b65630e83 cmd/containerboot: switch to IPN bus monitoring instead of polling.
We still have to shell out to `tailscale up` because the container image's
API includes "arbitrary flags to tailscale up", unfortunately. But this
should still speed up startup a little, and also enables k8s-bound containers
to update their device information as new netmap updates come in.
