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.

It's not worth adding the v2 client just for these e2e tests. Remove

extension (#18252)
In dynamically changing environments where ACME account keys and certs
are stored separately, it can happen that the account key would get
deleted (and recreated) between issuances. If that is the case,
we currently fail renewals and the only way to recover is for users
to delete certs.
This adds a config knob to allow opting out of the replaces extension
and utilizes it in the Kubernetes operator where there are known
user workflows that could end up with this edge case.

exist (#18050)
This commit fixes a bug in our HA ingress reconciler where ingress resources would
be stuck in a deleting state should their associated VIP service be deleted within

The reconciliation loop would check for the existence of the VIP service and if not
found perform no additional cleanup steps. The code has been modified to continue
onwards even if the VIP service is not found.

Adds cmd/cigocacher as the client to cigocached for Go caching over
HTTP. The HTTP cache is best-effort only, and builds will fall back to
disk-only cache if it's not available, much like regular builds.
Not yet used in CI; that will follow in another PR once we have runners
available in this repo with the right network setup for reaching
cigocached.

This commit adds the `spec.replicas` field to the `Recorder` custom
resource that allows for a highly available deployment of `tsrecorder`
within a kubernetes cluster.
Many changes were required here as the code hard-coded the assumption
of a single replica. This has required a few loops, similar to what we
do for the `Connector` resource to create auth and state secrets. It
was also required to add a check to remove dangling state and auth
secrets should the recorder be scaled down.

This adds the --proxy-protocol flag to 'tailscale serve' and
'tailscale funnel', which tells the Tailscale client to prepend a PROXY
protocol[1] header when making connections to the proxied-to backend.
I've verified that this works with our existing funnel servers without
additional work, since they pass along source address information via
PeerAPI already.

The feature is currently in private alpha, so requires a tailnet feature
flag. Initially focuses on supporting the operator's own auth, because the
operator is the only device we maintain that uses static long-lived
credentials. All other operator-created devices use single-use auth keys.
Testing steps:
* Create a cluster with an API server accessible over public internet
* kubectl get --raw /.well-known/openid-configuration | jq '.issuer'
* Create a federated OAuth client in the Tailscale admin console with:
* The issuer from the previous step
* Subject claim `system:serviceaccount:tailscale:operator`
* Write scopes services, devices:core, auth_keys
* Tag tag:k8s-operator
* Allow the Tailscale control plane to get the public portion of
the ServiceAccount token signing key without authentication:
* kubectl create clusterrolebinding oidc-discovery \
--clusterrole=system:service-account-issuer-discovery \
--group=system:unauthenticated
* helm install --set oauth.clientId=... --set oauth.audience=...

In #17639 we moved the subscription into NewLogger to ensure we would not race
subscribing with shutdown of the eventbus client. Doing so fixed that problem,
but exposed another: As we were only servicing events occasionally when waiting
for the network to come up, we could leave the eventbus to stall in cases where
a number of network deltas arrived later and weren't processed.
To address that, let's separate the concerns: As before, we'll Subscribe early
to avoid conflicts with shutdown; but instead of using the subscriber directly
to determine readiness, we'll keep track of the last-known network state in a
selectable condition that the subscriber updates for us. When we want to wait,
we'll wait on that condition (or until our context ends), ensuring all the
events get processed in a timely manner.

The connstats package was an unnecessary layer of indirection.
It was seperated out of wgengine/netlog so that net/tstun and
wgengine/magicsock wouldn't need a depenedency on the concrete
implementation of network flow logging.
Instead, we simply register a callback for counting connections.
This PR does the bare minimum work to prepare tstun and magicsock
to only care about that callback.
A future PR will delete connstats and merge it into netlog.

Saves 45 KB from the min build, no longer pulling in deephash or
util/hashx, both with unsafe code.
It can actually be more efficient to not use deephash, as you don't
have to walk all bytes of all fields recursively to answer that two
things are not equal. Instead, you can just return false at the first
difference you see. And then with views (as we use ~everywhere
nowadays), the cloning the old value isn't expensive, as it's just a
pointer under the hood.

Add and wire up event publishers for these two event types in the AppConnector.
Nothing currently subscribes to them, so this is harmless. Subscribers for
these events will be added in a near-future commit.
As part of this, move the appc.RouteInfo type to the types/appctype package.
It does not contain any package-specific details from appc. Beside it, add
appctype.RouteUpdate to carry route update event state, likewise not specific
to appc. Update all usage of the appc.* types throughout to use appctype.*
instead, and update depaware files to reflect these changes.
Add a Close method to the AppConnector to make sure the client gets cleaned up
when the connector is dropped (we re-create connectors).
Update the unit tests in the appc package to also check the events published
alongside calls to the RouteAdvertiser.
For now the tests still rely on the RouteAdvertiser for correctness; this is OK
for now as the two methods are always performed together. In the near future,
we need to rework the tests so not require that, but that will require building
some more test fixtures that we can handle separately.
