cmd/tailscale: shrink QR codes using half blocks (#17084)
When running `tailscale up --qr`, the QR code is rendered using
two full blocks ██ to form a square pixel. This is a problem for
people with smaller terminals, because the output is 37 lines high.
All modern terminals support half block characters, like ▀ and ▄,
which only takes 19 lines and can easily fit in a regular terminal
window.

For example, https://login.tailscale.com/a/0123456789 is now rendered:

```
user@host:~$ tailscale up --qr

To render a QR code with full blocks, like we did in the past, use the
new `--qr-format` flag:

```
user@host:~$ tailscale up --qr --qr-format=large

But it was also being used as the set of all features that are

Brad Fitzpatrick f1ded84454 cmd/tailscaled: add disabled debug file to force reflect for binary size experiments
This adds a file that's not compiled by default that exists just to
make it easier to do binary size checks, probing what a binary would
be like if it included reflect methods (as used by html/template, etc).

As an example, once tailscaled uses reflect.Type.MethodByName(non-const-string) anywhere,
the build jumps up by 14.5 MB:

    $ GOOS=linux GOARCH=amd64 ./tool/go build -tags=ts_include_cli,ts_omit_webclient,ts_omit_systray,ts_omit_debugeventbus -o before ./cmd/tailscaled

    $ GOOS=linux GOARCH=amd64 ./tool/go build -tags=ts_include_cli,ts_omit_webclient,ts_omit_systray,ts_omit_debugeventbus,ts_debug_forcereflect -o after ./cmd/tailscaled

    $ ls -l before after
    -rwxr-xr-x@ 1 bradfitz  staff  41011861 Sep  9 07:28 before
    -rwxr-xr-x@ 1 bradfitz  staff  55610948 Sep  9 07:29 after

This is particularly pronounced with large deps like the AWS SDK. If you compare using ts_omit_aws:

    -rwxr-xr-x@ 1 bradfitz  staff  38284771 Sep  9 07:40 no-aws-no-reflect
    -rwxr-xr-x@ 1 bradfitz  staff  45546491 Sep  9 07:41 no-aws-with-reflect

That means adding AWS to a non-reflect binary adds 2.7 MB but adding
AWS to a reflect binary adds 10 MB.

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)

Previously, when attempting a risky action, the CLI printed a 5 second countdown saying
"Continuing in 5 seconds...". When the countdown finished, the CLI aborted rather than
continuing.

To avoid confusion, but also avoid accidentally continuing if someone (or an automated
process) fails to manually abort within the countdown, we now explicitly prompt for a
y/n response on whether or not to continue.

Brad Fitzpatrick d05e6dc09e util/syspolicy/policyclient: add policyclient.Client interface, start plumbing
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.

Brad Fitzpatrick cc532efc20 util/syspolicy/*: move syspolicy keys to new const leaf "pkey" package
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.

Add a ternary flag that unless set explicitly to false keeps the

If the flag is false, add functionality on startup to migrate
oidc-funnel-clients.json to oauth-clients.json if it doesn’t exist.
If the flag is false, modify endpoints to behave similarly regardless
of funnel, tailnet, or localhost. They will all verify client ID & secret
when appropriate per RFC 6749. The authorize endpoint will no longer change
based on funnel status or nodeID.

Add extra tests verifying TSIDP endpoints behave as expected
with the new flag.

Safely create the redirect URL from what's passed into the
authorize endpoint.

Now that there is first-class support for Go,
we should migrate over to using it and delete syncs.WaitGroup.

James Tucker f5d3c59a92 wgengine/magicsock: shorten process internal DERP queue
DERP writes go via TCP and the host OS will have plenty of buffer space.
We've observed in the wild with a backed up TCP socket kernel side
buffers of >2.4MB. The DERP internal queue being larger causes an
increase in the probability that the contents of the backbuffer are
"dead letters" - packets that were assumed to be lost.

A first step to improvement is to size this queue only large enough to
avoid some of the initial connect stall problem, but not large enough
that it is contributing in a substantial way to buffer bloat /
dead-letter retention.

cmd/k8s-proxy,k8s-operator: fix serve config for userspace mode (#16919)
The serve code leaves it up to the system's DNS resolver and netstack to
figure out how to reach the proxy destination. Combined with k8s-proxy
running in userspace mode, this means we can't rely on MagicDNS being
available or tailnet IPs being routable. I'd like to implement that as a
feature for serve in userspace mode, but for now the safer fix to get
kube-apiserver ProxyGroups consistently working in all environments is to
switch to using localhost as the proxy target instead.

This has a small knock-on in the code that does WhoIs lookups, which now
needs to check the X-Forwarded-For header that serve populates to get
the correct tailnet IP to look up, because the request's remote address
will be loopback.

Fran Bull d986baa18f tsconsensus,cmd/natc: add 'follower only' bootstrap option
Currently consensus has a bootstrap routine where a tsnet node tries to
join each other node with the cluster tag, and if it is not able to join
any other node it starts its own cluster.

That algorithm is racy, and can result in split brain (more than one
leader/cluster) if all the nodes for a cluster are started at the same
time.

Add a FollowOnly argument to the bootstrap function. If provided this
tsnet node will never lead, it will try (and retry with exponential back
off) to follow any node it can contact.

Add a --follow-only flag to cmd/natc that uses this new tsconsensus
functionality.

Also slightly reorganize some arguments into opts structs.

cmd/viewer, types/views: implement support for json/v2 (#16852)
This adds support for having every viewer type implement
jsonv2.MarshalerTo and jsonv2.UnmarshalerFrom.

This provides a significant boost in performance
as the json package no longer needs to validate
the entirety of the JSON value outputted by MarshalJSON,
nor does it need to identify the boundaries of a JSON value
in order to call UnmarshalJSON.

For deeply nested and recursive MarshalJSON or UnmarshalJSON calls,
this can improve runtime from O(N²) to O(N).

This still references "github.com/go-json-experiment/json"
instead of the experimental "encoding/json/v2" package
now available in Go 1.25 under goexperiment.jsonv2
so that code still builds without the experiment tag.
Of note, the "github.com/go-json-experiment/json" package
aliases the standard library under the right build conditions.

Nick Khyl c87f44b687 cmd/tailscale/cli: use DNS name instead of Location to hide Mullvad exit nodes from status output
Previously, we used a non-nil Location as an indicator that a peer is a Mullvad exit node.
However, this is not, or no longer, reliable, since regular exit nodes may also have a non-nil Location,
such as when traffic steering is enabled for a tailnet.

In this PR, we update the plaintext `tailscale status` output to omit only Mullvad exit nodes, rather than all
exit nodes with a non-nil Location. The JSON output remains unchanged and continues to include all peers.

The Kubernetes API server proxy is getting the ability to serve on a
Tailscale Service instead of individual node names. Update the configure
kubeconfig sub-command to accept arguments that look like a Tailscale
Service. Note, we can't know for sure whether a peer is advertising a
Tailscale Service, we can only guess based on the ExtraRecords in the
netmap and that IP showing up in a peer's AllowedIPs.

Also adds an --http flag to allow targeting individual proxies that can
be adverting on http for their node name, and makes the command a bit
more forgiving on the range of inputs it accepts and how eager it is to
print the help text when the input is obviously wrong.

all-kube: create Tailscale Service for HA kube-apiserver ProxyGroup (#16572)
Adds a new reconciler for ProxyGroups of type kube-apiserver that will
provision a Tailscale Service for each replica to advertise. Adds two
new condition types to the ProxyGroup, TailscaleServiceValid and
TailscaleServiceConfigured, to post updates on the state of that
reconciler in a way that's consistent with the service-pg reconciler.
The created Tailscale Service name is configurable via a new ProxyGroup
field spec.kubeAPISserver.ServiceName, which expects a string of the
form "svc:<dns-label>".

Lots of supporting changes were needed to implement this in a way that's
consistent with other operator workflows, including:

* Pulled containerboot's ensureServicesUnadvertised and certManager into
  kube/ libraries to be shared with k8s-proxy. Use those in k8s-proxy to
  aid Service cert sharing between replicas and graceful Service shutdown.
* For certManager, add an initial wait to the cert loop to wait until
  the domain appears in the devices's netmap to avoid a guaranteed error
  on the first issue attempt when it's quick to start.
* Made several methods in ingress-for-pg.go and svc-for-pg.go into
  functions to share with the new reconciler
* Added a Resource struct to the owner refs stored in Tailscale Service
  annotations to be able to distinguish between Ingress- and ProxyGroup-
  based Services that need cleaning up in the Tailscale API.
* Added a ListVIPServices method to the internal tailscale client to aid
  cleaning up orphaned Services
* Support for reading config from a kube Secret, and partial support for
  config reloading, to prevent us having to force Pod restarts when
  config changes.
* Fixed up the zap logger so it's possible to set debug log level.

* cmd/tailscale/cli: Add service flag to serve command

This commit adds the service flag to serve command which allows serving a service and add the service
to the advertisedServices field in prefs (What advertise command does that will be removed later).

When adding proxies, TCP proxies and WEB proxies work the same way as normal serve, just under a
different DNSname. There is a services specific L3 serving mode called Tun, can be set via --tun flag.
Serving a service is always in --bg mode. If --bg is explicitly set t o false, an error message will
be sent out. The restriction on proxy target being localhost or 127.0.0.1 also applies to services.

When removing proxies, TCP proxies can be removed with type and port flag and off argument. Web proxies
can be removed with type, port, setPath flag and off argument. To align with normal serve, when setPath
is not set, all handler under the hostport will be removed. When flags are not set but off argument was
passed by user, it will be a noop. Removing all config for a service will be available later with a new
subcommand clear.

cmd/{k8s-operator,k8s-proxy}: add kube-apiserver ProxyGroup type (#16266)
Adds a new k8s-proxy command to convert operator's in-process proxy to
a separately deployable type of ProxyGroup: kube-apiserver. k8s-proxy
reads in a new config file written by the operator, modelled on tailscaled's
conffile but with some modifications to ensure multiple versions of the
config can co-exist within a file. This should make it much easier to
support reading that config file from a Kube Secret with a stable file name.

To avoid needing to give the operator ClusterRole{,Binding} permissions,
the helm chart now optionally deploys a new static ServiceAccount for
the API Server proxy to use if in auth mode.

Proxies deployed by kube-apiserver ProxyGroups currently work the same as
the operator's in-process proxy. They do not yet leverage Tailscale Services
for presenting a single HA DNS name.

With this change, policy enforcement and exit node resolution can happen in separate steps,
since enforcement no longer depends on resolving the suggested exit node. This keeps policy
enforcement synchronous (e.g., when switching profiles), while allowing exit node resolution
to be asynchronous on netmap updates, link changes, etc.

Additionally, the new preference will be used to let GUIs and CLIs switch back to "auto" mode
after a manual exit node override, which is necessary for tailscale/corp#29969.

cmd/{containerboot,k8s-operator}: use state Secret for checking device auth (#16328)
Previously, the operator checked the ProxyGroup status fields for
information on how many of the proxies had successfully authed. Use
their state Secrets instead as a more reliable source of truth.

containerboot has written device_fqdn and device_ips keys to the
state Secret since inception, and pod_uid since 1.78.0, so there's
no need to use the API for that data. Read it from the state Secret
for consistency. However, to ensure we don't read data from a
previous run of containerboot, make sure we reset containerboot's
state keys on startup.

One other knock-on effect of that is ProxyGroups can briefly be
marked not Ready while a Pod is restarting. Introduce a new
ProxyGroupAvailable condition to more accurately reflect
when downstream controllers can implement flows that rely on a
ProxyGroup having at least 1 proxy Pod running.

Anton Tolchanov db34cdcfe7 cmd/tailscale/cli: add a risk message about rp_filter
We already present a health warning about this, but it is easy to miss
on a server when blackholing traffic makes it unreachable.

In addition to a health warning, present a risk message when exit node
is enabled.

Example:

```
$ tailscale up --exit-node=lizard
The following issues on your machine will likely make usage of exit nodes impossible:
- interface "ens4" has strict reverse-path filtering enabled
- interface "tailscale0" has strict reverse-path filtering enabled
Please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310
To skip this warning, use --accept-risk=linux-strict-rp-filter
$
```

cmd/containerboot: allow setting --accept-dns via TS_EXTRA_ARGS again (#16129)
In 1.84 we made 'tailscale set'/'tailscale up' error out if duplicate
command line flags are passed.
This broke some container configurations as we have two env vars that
can be used to set --accept-dns flag:
- TS_ACCEPT_DNS- specifically for --accept-dns
- TS_EXTRA_ARGS- accepts any arbitrary 'tailscale up'/'tailscale set'
flag.

We default TS_ACCEPT_DNS to false (to make the container behaviour more
declarative), which with the new restrictive CLI behaviour resulted in
failure for users who had set --accept-dns via TS_EXTRA_ARGS as the flag would be
provided twice.

This PR re-instates the previous behaviour by checking if TS_EXTRA_ARGS
contains --accept-dns flag and if so using its value to override TS_ACCEPT_DNS.

Nick Khyl 191afd3390 net/tshttpproxy: fix WDAP/PAC proxy detection on Win10 1607 and earlier
Using WINHTTP_AUTOPROXY_ALLOW_AUTOCONFIG on Windows versions older than Windows 10 1703 (build 15063)
is not supported and causes WinHttpGetProxyForUrl to fail with ERROR_INVALID_PARAMETER. This results in failures
reaching the control on environments where a proxy is required.

We use wingoes version detection to conditionally set the WINHTTP_AUTOPROXY_ALLOW_AUTOCONFIG flag
on Windows builds greater than 15063.

While there, we also update proxy detection to use WINHTTP_AUTO_DETECT_TYPE_DNS_A, as DNS-based proxy discovery
might be required with Active Directory and in certain other environments.

cmd/derper: fix mesh auth for DERP servers (#16061)
To authenticate mesh keys, the DERP servers used a simple == comparison,
which is susceptible to a side channel timing attack.

By extracting the mesh key for a DERP server, an attacker could DoS it
by forcing disconnects using derp.Client.ClosePeer. They could also
enumerate the public Wireguard keys, IP addresses and ports for nodes
connected to that DERP server.

DERP servers configured without mesh keys deny all such requests.

This patch also extracts the mesh key logic into key.DERPMesh, to
prevent this from happening again.

M. J. Fromberger 418e19fb5e portmapper: update NewClient to use a Config argument
In preparation for adding more parameters (and later, moving some away), rework
the portmapper constructor to accept its arguments on a Config struct rather
than positionally.

This is a breaking change to the function signature, but one that is very easy
to update, and a search of GitHub reveals only six instances of usage outside
clones and forks of Tailscale itself, that are not direct copies of the code
fixed up here.

While we could stub in another constructor, I think it is safe to let those
folks do the update in-place, since their usage is already affected by other
changes we can't test for anyway.

M. J. Fromberger ffb22ee353 all: construct new System values with an event bus pre-populated
Although, at the moment, we do not yet require an event bus to be present, as
we start to add more pieces we will want to ensure it is always available.  Add
a new constructor and replace existing uses of new(tsd.System) throughout.
Update generated files for import changes.

feature/{condregister,relayserver}: implement the skeleton for the relayserver feature (#15699)
This feature is "registered" as an ipnlocal.Extension, and
conditionally linked depending on GOOS and ts_omit_relayserver build
tag.

The feature is not linked on iOS in attempt to limit the impact to
binary size and resulting effect of pushing up against NetworkExtension
limits. Eventually we will want to support the relay server on iOS,
specifically on the Apple TV. Apple TVs are well-fitted to act as
underlay relay servers as they are effectively always-on servers.

This skeleton begins to tie a PeerAPI endpoint to a net/udprelay.Server.
The PeerAPI endpoint is currently no-op as
extension.shouldRunRelayServer() always returns false. Follow-up commits
will implement extension.shouldRunRelayServer().

Nick Khyl 4941cd7c73 cmd/tailscaled,ipn/{auditlog,desktop,ipnext,ipnlocal},tsd: extract LocalBackend extension interfaces and implementation
In this PR, we refactor the LocalBackend extension system, moving from direct callbacks to a more organized extension host model.

Specifically, we:
- Extract interface and callback types used by packages extending LocalBackend functionality into a new ipn/ipnext package.
- Define ipnext.Host as a new interface that bridges extensions with LocalBackend.
  It enables extensions to register callbacks and interact with LocalBackend in a concurrency-safe, well-defined, and controlled way.
- Move existing callback registration and invocation code from ipnlocal.LocalBackend into a new type called ipnlocal.ExtensionHost,
  implementing ipnext.Host.
- Improve docs for existing types and methods while adding docs for the new interfaces.
- Add test coverage for both the extracted and the new code.
- Remove ipn/desktop.SessionManager from tsd.System since ipn/desktop is now self-contained.
- Update existing extensions (e.g., ipn/auditlog and ipn/desktop) to use the new interfaces where appropriate.

We're not introducing new callback and hook types (e.g., for ipn.Prefs changes) just yet, nor are we enhancing current callbacks,
such as by improving conflict resolution when more than one extension tries to influence profile selection via a background profile resolver.
These further improvements will be submitted separately.

cmd/tailscale,ipn: add relay-server-port "tailscale set" flag and Prefs field (#15594)
This flag is currently no-op and hidden. The flag does round trip
through the related pref. Subsequent commits will tie them to
net/udprelay.Server. There is no corresponding "tailscale up" flag,
enabling/disabling of the relay server will only be supported via
"tailscale set".

This is a string flag in order to support disablement via empty string
as a port value of 0 means "enable the server and listen on a random
unused port". Disablement via empty string also follows existing flag
convention, e.g. advertise-routes.

Early internal discussions settled on "tailscale set --relay="<port>",
but the author felt this was too ambiguous around client vs server, and
may cause confusion in the future if we add related flags.

Simon Law 7e296923ab cmd/tailscale: test for new flags in tailscale up
`tailscale set` was created to set preferences, which used to be
overloaded into `tailscale up`. To move people over to the new
command, `up` was supposed to be frozen and no new preference flags
would be added. But people forgot, there was no test to warn them, and
so new flags were added anyway.

TestUpFlagSetIsFrozen complains when new flags are added to
`tailscale up`. It doesn’t try all combinations of GOOS, but since
the CI builds in every OS, the pull-request tests should cover this.

cmd/{containerboot,k8s-operator},kube/kubetypes: unadvertise ingress services on shutdown (#15451)
Ensure no services are advertised as part of shutting down tailscaled.
Prefs are only edited if services are currently advertised, and they're
edited we wait for control's ~15s (+ buffer) delay to failover.

Note that editing prefs will trigger a synchronous write to the state
Secret, so it may fail to persist state if the ProxyGroup is getting
scaled down and therefore has its RBAC deleted at the same time, but that
failure doesn't stop prefs being updated within the local backend,
doesn't  affect connectivity to control, and the state Secret is
about to get deleted anyway, so the only negative side effect is a harmless
error log during shutdown. Control still learns that the node is no
longer advertising the service and triggers the failover.

Note that the first version of this used a PreStop lifecycle hook, but
that only supports GET methods and we need the shutdown to trigger side
effects (updating prefs) so it didn't seem appropriate to expose that
functionality on a GET endpoint that's accessible on the k8s network.

James Tucker 8e1aa86bdb cmd/natc: attempt to match IP version between upstream and downstream
As IPv4 and IPv6 end up with different MSS and different congestion
control strategies, proxying between them can really amplify TCP
meltdown style conditions in many real world network conditions, such as
with higher latency, some loss, etc.

Attempt to match up the protocols, otherwise pick a destination address
arbitrarily. Also shuffle the target address to spread load across
upstream load balancers.
