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 is step 4 of making syspolicy a build-time feature.
This adds a policyclient.Get() accessor to return the correct
implementation to use: either the real one, or the no-op one. (A third
type, a static one for testing, also exists, so in general a
policyclient.Client should be plumbed around and not always fetched
via policyclient.Get whenever possible, especially if tests need to use
alternate syspolicy)

RELNOTE=Fix CSRF errors in the client Web UI
Replace gorilla/csrf with a Sec-Fetch-Site based CSRF protection
middleware that falls back to comparing the Host & Origin headers if no
SFS value is passed by the client.
Add an -origin override to the web CLI that allows callers to specify
the origin at which the web UI will be available if it is hosted behind
a reverse proxy or within another application via CGI.

For 9dd6af1f6d
Update client/web and safeweb to correctly signal to the csrf middleware
whether the request is being served over TLS. This determines whether
Origin and Referer header checks are strictly enforced. The gorilla
library previously did not enforce these checks due to a logic bug based
on erroneous use of the net/http.Request API. The patch to fix this also
inverts the library behavior to presume that every request is being
served over TLS, necessitating these changes.

Change the type of the `IPv4` and `IPv6` members in the `nodeData`
struct to be `netip.Addr` instead of `string`.
We were previously calling `String()` on this struct, which returns
"invalid IP" when the `netip.Addr` is its zero value, and passing this
value into the aforementioned attributes.
This caused rendering issues on the frontend
as we were assuming that the value for `IPv4` and `IPv6` would be falsy
in this case.
The zero value for a `netip.Addr` marshalls to an empty string instead
which is the behaviour we want downstream.

This is simply an extra check to prevent hypothetical issues if a prefix
such as `--prefix="javascript:alert(1)"` was provided. This isn't
really necessary since the prefix is a configuration flag provided by
the device owner, not user input. But it does enforce that we are
always interpreting the provided value as a path relative to the root.

Throughout the web UI, we present the tailscale addresses for the
self node. In the case of the node being shared out with a user
from another tailnet, the peer viewer may actually know the node
by a different IP than the node knows itself as (Tailscale IPs
can be configured as desired on a tailnet level). This change
includes two fixes:
1. Present the self node's addresses in the frontend as the addresses
the viewing node knows it as (i.e. the addresses the viewing node
uses to access the web client).
2. We currently redirect the viewer to the Tailscale IPv4 address if
viewing it by MagicDNS name, or any other name that maps to the
Tailscale node. When doing this redirect, which is primarily added
for DNS rebinding protection, we now check the address the peer
knows this node as, and redirect to specifically that IP.

The client has changed a bit since we introduced the path prefix. It is
now used for two things:
- its original purpose, of ensuring that when the client is run in CGI
mode at arbitrary paths, then relative paths for assets continue to
work
- we also now pass the path to the frontend and use wouter to manage
routes for the various subpages of the client.
When the client is run behind a reverse proxy (as it is in Home
Assistant), it is common for the proxy to rewrite the request so that
the backend application doesn't see the path it's being served at. In
this case, we don't need to call enforcePrefix, since it's already
stripped before it reaches us. However, wouter (or react router
library) still sees the original path in the browser, and needs to know
what part of it is the prefix that needs to be stripped off.
We're handling this by now only calling enforcePrefix when run in CGI
mode. For Home Assistant, or any other platform that runs the client
behind a reverse proxy with a custom path, they will still need to pass
the `-prefix` flag to `tailscale web`, but we will only use it for route
handling in the frontend.

This commit makes some restructural changes to how we handle api
posting from the web client frontend.
Now that we're using SWR, we have less of a need for hooks like
useNodeData that return a useSWR response alongside some mutation
callbacks. SWR makes it easy to mutate throughout the UI without
needing access to the original data state in order to reflect
updates. So, we can fetch data without having to tie it to post
callbacks that have to be passed around through components.
In an effort to consolidate our posting endpoints, and make it
easier to add more api handlers cleanly in the future, this change
introduces a new `useAPI` hook that returns a single `api` callback
that can make any changes from any component in the UI. The hook
itself handles using SWR to mutate the relevant data keys, which
get globally reflected throughout the UI.
As a concurrent cleanup, node types are also moved to their own
types.ts file, to consolidate data types across the app.

Use the packet filter rules to determine if any device is allowed to
connect on port 5252. This does not check whether a specific device can
connect (since we typically don't know the source device when this is
used). Nor does it specifically check for wide-open ACLs, which is
something we may provide a warning about in the future.
Update the login popover content to display information when the src
device is unable to connect to the dst device over its Tailscale IP. If
we know it's an ACL issue, mention that, otherwise list a couple of
things to check. In both cases, link to a placeholder URL to get more
information about web client connection issues.
