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 is step 2 of ~4, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
Step 1 was #16984.
In this second step, the util/syspolicy/policyclient package is added
with the policyclient.Client interface. This is the interface that's
always present (regardless of build tags), and is what code around the
tree uses to ask syspolicy/MDM questions.
There are two implementations of policyclient.Client for now:
1) NoPolicyClient, which only returns default values.
2) the unexported, temporary 'globalSyspolicy', which is implemented
in terms of the global functions we wish to later eliminate.
This then starts to plumb around the policyclient.Client to most callers.
Future changes will plumb it more. When the last of the global func
callers are gone, then we can unexport the global functions and make a
proper policyclient.Client type and constructor in the syspolicy
package, removing the globalSyspolicy impl out of tsd.
The final change will sprinkle build tags in a few more places and
lock it in with dependency tests to make sure the dependencies don't
later creep back in.

This is step 1 of ~3, breaking up #14720 into reviewable chunks, with
the aim to make syspolicy be a build-time configurable feature.
In this first (very noisy) step, all the syspolicy string key
constants move to a new constant-only (code-free) package. This will
make future steps more reviewable, without this movement noise.
There are no code or behavior changes here.
The future steps of this series can be seen in #14720: removing global
funcs from syspolicy resolution and using an interface that's plumbed
around instead. Then adding build tags.

With the upcoming syspolicy changes, it's imperative that all syspolicy keys are defined in the syspolicy package
for proper registration. Otherwise, the corresponding policy settings will not be read.
This updates a couple of places where we still use string literals rather than syspolicy consts.

If an optional `hwaddrs` URL parameter is present, add network interface
hardware addresses to the posture identity response.
Just like with serial numbers, this requires client opt-in via MDM or
