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'

If we get a packet in over some DERP and don't otherwise know how to
reply (no known DERP home or UDP endpoint), this makes us use the
DERP connection on which we received the packet to reply. This will
almost always be our own home DERP region.
This is particularly useful for large one-way nodes (such as
hello.ts.net) that don't actively reach out to other nodes, so don't
need to be told the DERP home of peers. They can instead learn the
DERP home upon getting the first connection.
This can also help nodes from a slow or misbehaving control plane.

The reason they weren't working was because the cmd/tta agent in the
guest was dialing out to the test and the vnet couldn't map its global
unicast IPv6 address to a node as it was just using a
map[netip.Addr]*node and blindly trusting the *node was
populated. Instead, it was nil, so the agent connection fetching
didn't work for its RoundTripper and the test could never drive the
node. That map worked for IPv4 but for IPv6 we need to use the method
that takes into account the node's IPv6 SLAAC address. Most call sites
had been converted but I'd missed that one.
Also clean up some debug, and prohibit nodes' link-local unicast
addresses from dialing 2000::/3 directly for now. We can allow that to
be configured opt-in later (some sort of IPv6 NAT mode. Whatever it's
called.) That mode was working on accident, but was confusing: Linux
would do source address selection from link local for the first few
seconds and then after SLAAC and DAD, switch to using the global
unicast source address. Be consistent for now and force it to use the
global unicast.

Using https://github.com/gokrazy/gokrazy/pull/275
This is much lower latency than logcatcher, which is higher latency
and chunkier. And this is better than getting it via 'tailscale debug
daemon-logs', which misses early interesting logs.

This adds a new NodeAgentClient type that can be used to
invoke the LocalAPI using the LocalClient instead of
handcrafted URLs. However, there are certain cases where
it does make sense for the node agent to provide more
functionality than whats possible with just the LocalClient,
as such it also exposes a http.Client to make requests directly.
