This file was never truly necessary and has never actually been used in
the history of Tailscale's open source releases.
A Brief History of AUTHORS files
---
The AUTHORS file was a pattern developed at Google, originally for
Chromium, then adopted by Go and a bunch of other projects. The problem
was that Chromium originally had a copyright line only recognizing
Google as the copyright holder. Because Google (and most open source
projects) do not require copyright assignemnt for contributions, each
contributor maintains their copyright. Some large corporate contributors
then tried to add their own name to the copyright line in the LICENSE
file or in file headers. This quickly becomes unwieldy, and puts a
tremendous burden on anyone building on top of Chromium, since the
license requires that they keep all copyright lines intact.
The compromise was to create an AUTHORS file that would list all of the
copyright holders. The LICENSE file and source file headers would then
include that list by reference, listing the copyright holder as "The
Chromium Authors".
This also become cumbersome to simply keep the file up to date with a
high rate of new contributors. Plus it's not always obvious who the
copyright holder is. Sometimes it is the individual making the
contribution, but many times it may be their employer. There is no way
for the proejct maintainer to know.
Eventually, Google changed their policy to no longer recommend trying to
keep the AUTHORS file up to date proactively, and instead to only add to
it when requested: https://opensource.google/docs/releasing/authors.
They are also clear that:
> Adding contributors to the AUTHORS file is entirely within the
> project's discretion and has no implications for copyright ownership.
It was primarily added to appease a small number of large contributors
that insisted that they be recognized as copyright holders (which was
entirely their right to do). But it's not truly necessary, and not even
the most accurate way of identifying contributors and/or copyright
holders.
In practice, we've never added anyone to our AUTHORS file. It only lists
Tailscale, so it's not really serving any purpose. It also causes
confusion because Tailscalars put the "Tailscale Inc & AUTHORS" header
in other open source repos which don't actually have an AUTHORS file, so
it's ambiguous what that means.
Instead, we just acknowledge that the contributors to Tailscale (whoever
they are) are copyright holders for their individual contributions. We
also have the benefit of using the DCO (developercertificate.org) which
provides some additional certification of their right to make the
contribution.
The source file changes were purely mechanical with:
git ls-files | xargs sed -i -e 's/\(Tailscale Inc &\) AUTHORS/\1 contributors/g'

This commit contains the implementation of multi-tailnet support within the Kubernetes Operator
Each of our custom resources now expose the `spec.tailnet` field. This field is a string that must match the name of an existing `Tailnet` resource. A `Tailnet` resource looks like this:
```yaml
apiVersion: tailscale.com/v1alpha1
kind: Tailnet
metadata:
name: example # This is the name that must be referenced by other resources
spec:
credentials:
secretName: example-oauth
```
Each `Tailnet` references a `Secret` resource that contains a set of oauth credentials. This secret must be created in the same namespace as the operator:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: example-oauth # This is the name that's referenced by the Tailnet resource.
namespace: tailscale
stringData:
client_id: "client-id"
client_secret: "client-secret"
```
When created, the operator performs a basic check that the oauth client has access to all required scopes. This is done using read actions on devices, keys & services. While this doesn't capture a missing "write" permission, it catches completely missing permissions. Once this check passes, the `Tailnet` moves into a ready state and can be referenced. Attempting to use a `Tailnet` in a non-ready state will stall the deployment of `Connector`s, `ProxyGroup`s and `Recorder`s until the `Tailnet` becomes ready.
The `spec.tailnet` field informs the operator that a `Connector`, `ProxyGroup`, or `Recorder` must be given an auth key generated using the specified oauth client. For backwards compatibility, the set of credentials the operator is configured with are considered the default. That is, where `spec.tailnet` is not set, the resource will be deployed in the same tailnet as the operator.

Adds a new reconciler for ProxyGroups of type kube-apiserver that will
provision a Tailscale Service for each replica to advertise. Adds two
new condition types to the ProxyGroup, TailscaleServiceValid and
TailscaleServiceConfigured, to post updates on the state of that
reconciler in a way that's consistent with the service-pg reconciler.
The created Tailscale Service name is configurable via a new ProxyGroup
field spec.kubeAPISserver.ServiceName, which expects a string of the
form "svc:<dns-label>".
Lots of supporting changes were needed to implement this in a way that's
consistent with other operator workflows, including:
* Pulled containerboot's ensureServicesUnadvertised and certManager into
kube/ libraries to be shared with k8s-proxy. Use those in k8s-proxy to
aid Service cert sharing between replicas and graceful Service shutdown.
* For certManager, add an initial wait to the cert loop to wait until
the domain appears in the devices's netmap to avoid a guaranteed error
on the first issue attempt when it's quick to start.
* Made several methods in ingress-for-pg.go and svc-for-pg.go into
functions to share with the new reconciler
* Added a Resource struct to the owner refs stored in Tailscale Service
annotations to be able to distinguish between Ingress- and ProxyGroup-
based Services that need cleaning up in the Tailscale API.
* Added a ListVIPServices method to the internal tailscale client to aid
cleaning up orphaned Services
* Support for reading config from a kube Secret, and partial support for
config reloading, to prevent us having to force Pod restarts when
config changes.
* Fixed up the zap logger so it's possible to set debug log level.

Adds a new k8s-proxy command to convert operator's in-process proxy to
a separately deployable type of ProxyGroup: kube-apiserver. k8s-proxy
reads in a new config file written by the operator, modelled on tailscaled's
conffile but with some modifications to ensure multiple versions of the
config can co-exist within a file. This should make it much easier to
support reading that config file from a Kube Secret with a stable file name.
To avoid needing to give the operator ClusterRole{,Binding} permissions,
the helm chart now optionally deploys a new static ServiceAccount for
the API Server proxy to use if in auth mode.
Proxies deployed by kube-apiserver ProxyGroups currently work the same as
the operator's in-process proxy. They do not yet leverage Tailscale Services
for presenting a single HA DNS name.

(#16328)
Previously, the operator checked the ProxyGroup status fields for
information on how many of the proxies had successfully authed. Use
their state Secrets instead as a more reliable source of truth.
containerboot has written device_fqdn and device_ips keys to the
state Secret since inception, and pod_uid since 1.78.0, so there's
no need to use the API for that data. Read it from the state Secret
for consistency. However, to ensure we don't read data from a
previous run of containerboot, make sure we reset containerboot's
state keys on startup.
One other knock-on effect of that is ProxyGroups can briefly be
marked not Ready while a Pod is restarting. Introduce a new
ProxyGroupAvailable condition to more accurately reflect
when downstream controllers can implement flows that rely on a
ProxyGroup having at least 1 proxy Pod running.

don't terminate while cluster traffic is still routed to them (#14436)
cmd/{containerboot,k8s-operator},kube: add preshutdown hook for egress PG proxies
This change is part of work towards minimizing downtime during update
rollouts of egress ProxyGroup replicas.
This change:
- updates the containerboot health check logic to return Pod IP in headers,
if set
- always runs the health check for egress PG proxies
- updates ClusterIP Services created for PG egress endpoints to include
the health check endpoint
- implements preshutdown endpoint in proxies. The preshutdown endpoint
logic waits till, for all currently configured egress services, the ClusterIP
Service health check endpoint is no longer returned by the shutting-down Pod
(by looking at the new Pod IP header).
- ensures that kubelet is configured to call the preshutdown endpoint
This reduces the possibility that, as replicas are terminated during an update,
a replica gets terminated to which cluster traffic is still being routed via
the ClusterIP Service because kube proxy has not yet updated routig rules.
This is not a perfect check as in practice, it only checks that the kube
proxy on the node on which the proxy runs has updated rules. However, overall
this might be good enough.
The preshutdown logic is disabled if users have configured a custom health check
port via TS_LOCAL_ADDR_PORT env var. This change throws a warnign if so and in
future setting of that env var for operator proxies might be disallowed (as users
shouldn't need to configure this for a Pod directly).
This is backwards compatible with earlier proxy versions.

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.

- update the Kubernetes cap rule definition with fields for granting

- adds a convenience function to produce tailcfg.RawMessage from an
arbitrary cap rule and a test for it.

"dst": ["tag:k8s-operator"],
"app": {
"tailscale.com/cap/kubernetes": [{
"recorder": ["tag:my-recorder"]
“enforceRecorder”: true

},
}
]
This grant enforces `kubectl exec` sessions from tailnet clients,
matching `tag:eng` via API server proxy matching `tag:k8s-operator`
to be recorded and recording to be sent to a tsrecorder instance,
matching `tag:my-recorder`.
The type needs to be shared with control because we want
control to parse this cap and resolve tags to peer IPs.
