The Tailscale CLI has some methods to watch the IPN bus for
messages, say, the current netmap (`tailscale debug netmap`).
The Tailscale daemon supports this using a streaming HTTP
response. Sometimes, the client can close its connection
abruptly -- due to an interruption, or in the case of `debug netmap`,
intentionally after consuming one message.
If the server daemon is writing a response as the client closes
its end of the socket, the daemon typically encounters a "broken pipe"
error. The "Watch IPN Bus" handler currently logs such errors after
they're propagated by a JSON encoding/writer helper.
Since the Tailscale CLI nominally closes its socket with the daemon
in this slightly ungraceful way (viz. `debug netmap`), stop logging
these broken pipe errors as far as possible. This will help avoid
confounding users when they scan backend logs.

This commit is based on part of #17925, reworked as a separate package.
Add a package that can store and load netmap.NetworkMap values in persistent
storage, using a basic columnar representation. This commit includes a default
storage interface based on plain files, but the interface can be implemented
with more structured storage if we want to later.
The tests are set up to require that all the fields of the NetworkMap are
handled, except those explicitly designated as not-cached, and check that a
fully-populated value can round-trip correctly through the cache. Adding or
removing fields, either in the NetworkMap or in the cached representation, will
trigger either build failures (e.g., for type mismatch) or test failures (e.g.,
for representation changes or missing fields). This isn't quite as nice as
automatically updating the representation, which I also prototyped, but is much
simpler to maintain and less code.
This commit does not yet hook up the cache to the backend, that will be a
subsequent change.

Someone asked me if we use DNS-over-HTTPS if the system's resolver is an
IP address that supports DoH and there's no global nameserver set (i.e.
no "Override DNS servers" set). I didn't know the answer offhand, and it
took a while for me to figure it out. The answer is yes, in cases where
we take over the system's DNS configuration and read the base config, we
do upgrade any DoH-capable resolver to use DoH. Here's a test that
verifies this behaviour (and hopefully helps as documentation the next
time someone has this question).

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'

In order to better manage per-profile data resources on the client, add methods
to the LocalBackend to support creation of per-profile directory structures in
local storage. These methods build on the existing TailscaleVarRoot config, and
have the same limitation (i.e., if no local storage is available, it will
report an error when used).
The immediate motivation is to support netmap caching, but we can also use this
mechanism for other per-profile resources including pending taildrop files and
Tailnet Lock authority caches.
This commit only adds the directory-management plumbing; later commits will
handle migrating taildrop, TKA, etc. to this mechanism, as well as caching
network maps.

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.

tailscale version --json now includes an osVariant field that will report
one of macsys, appstore or darwin. We can extend this to other
platforms where tailscaled can have multiple personalities.
This also adds the concept of a platform-specific callback for querying
an explicit application identifier. On Apple, we can use
CFBundleGetIdentifier(mainBundle) to get the bundle identifier via cgo.
This removes all the ambiguity and lets us remove other less direct
methods (like env vars, locations, etc).

This change adds API to ipn.LocalBackend to retrieve the ETag when
querying for the current serve config. This allows consumers of
ipn.LocalBackend.SetServeConfig to utilize the concurrency control
offered by ETags. Previous to this change, utilizing serve config ETags
required copying the local backend's internal ETag calcuation.
The local API server was previously copying the local backend's ETag
calculation as described above. With this change, the local API server
now uses the new ETag retrieval function instead. Serve config ETags are
therefore now opaque to clients, in line with best practices.

Both Serve and PeerAPI broke when we moved the TailscaleInterfaceName
into State, which is updated asynchronously and may not be
available when we configure the listeners.
This extracts the explicit interface name property from netmon.State
and adds as a static struct with getters that have proper error
handling.
The bug is only found in sandboxed Darwin clients, where we
need to know the Tailscale interface details in order to set up the
listeners correctly (they must bind to our interface explicitly to escape
the network sandboxing that is applied by NECP).
Currently set only sandboxed macOS and Plan9 set this but it will
also be useful on Windows to simplify interface filtering in netns.

Policy editors, such as gpedit.msc and gpme.msc, rely on both the presence and the value of the
registry value to determine whether a policy is enabled. Unless an enabledValue is specified
explicitly, it defaults to REG_DWORD 1.
Therefore, we cannot rely on the same registry value to track the policy configuration state when
it is already used by a policy option, such as a dropdown. Otherwise, while the policy setting
will be written and function correctly, it will appear as Not Configured in the policy editor
due to the value mismatch (for example, REG_SZ "always" vs REG_DWORD 1).
In this PR, we update the DNSRegistration policy setting to use the DNSRegistrationConfigured
registry value for tracking. This change has no effect on the client side and exists solely to
satisfy ADMX and policy editor requirements.

Prior to this change, we were resetting the tsnet's serve config every
time tsnet.Server.Up was run. This is important to do on startup, to
prevent messy interactions with stale configuration when the code has
changed.
However, Up is frequently run as a just-in-case step (for example, by
Server.ListenTLS/ListenFunnel and possibly by consumers of tsnet). When
the serve config is reset on each of these calls to Up, this creates
situations in which the serve config disappears unexpectedly. The
solution is to reset the serve config only on the first call to Up.
