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'

GCP Certificate Manager requires an email contact on ACME accounts.
Add --acme-email flag that is required for --certmode=gcp and
optional for --certmode=letsencrypt.
Fixes#18277

Add --certmode=gcp for using Google Cloud Certificate Manager's
public CA instead of Let's Encrypt. GCP requires External Account
Binding (EAB) credentials for ACME registration, so this adds
--acme-eab-kid and --acme-eab-key flags.
The EAB key accepts both base64url and standard base64 encoding
to support both ACME spec format and gcloud output.

PR #17258 extracted `derp.Server` into `derp/derpserver.Server`.
This followup patch adds the following cleanups:
1. Rename `derp_server*.go` files to `derpserver*.go` to match
the package name.
2. Rename the `derpserver.NewServer` constructor to `derpserver.New`
to reduce stuttering.
3. Remove the unnecessary `derpserver.Conn` type alias.

This exports a number of things from the derp (generic + client) package
to be used by the new derpserver package, as now used by cmd/derper.
And then enough other misc changes to lock in that cmd/tailscaled can
be configured to not bring in tailscale.com/client/local. (The webclient
in particular, even when disabled, was bringing it in, so that's now fixed)

This fixes the implementation and test from #15208 which apparently
never worked.
Ignore the metacert when counting the number of expected certs
presented.
And fix the test, pulling out the TLSConfig setup code into something
shared between the real cmd/derper and the test.

For people who can't use LetsEncrypt because it's banned.
Per https://github.com/tailscale/tailscale/issues/11776#issuecomment-2520955317
This does two things:
1) if you run derper with --certmode=manual and --hostname=$IP_ADDRESS
we previously permitted, but now we also:
* auto-generate the self-signed cert for you if it doesn't yet exist on disk
* print out the derpmap configuration you need to use that
self-signed cert
2) teaches derp/derphttp's derp dialer to verify the signature of
self-signed TLS certs, if so declared in the existing
DERPNode.CertName field, which previously existed for domain fronting,
separating out the dial hostname from how certs are validates,
so it's not overloaded much; that's what it was meant for.
