95034e15a7 cmd/natc: fix ip allocation runtime
Avoid the unbounded runtime during random allocation, if random
allocation fails after a first pass at random through the provided
ranges, pick the next free address by walking through the allocated set.

The new ipx utilities provide a bitset based allocation pool, good for
small to moderate ranges of IPv4 addresses as used in natc.

6a9a7f35d9 cmd/tailscaled,ipn/{auditlog,ipnlocal},tsd: omit auditlog unless explicitly imported
In this PR, we update ipnlocal.LocalBackend to allow registering callbacks for control client creation
and profile changes. We also allow to register ipnauth.AuditLogFunc to be called when an auditable
action is attempted.

We then use all this to invert the dependency between the auditlog and ipnlocal packages and make
the auditlog functionality optional, where it only registers its callbacks via ipnlocal-provided hooks
when the auditlog package is imported.

We then underscore-import it when building tailscaled for Windows, and we'll explicitly
import it when building xcode/ipn-go-bridge for macOS. Since there's no default log-store
location for macOS, we'll also need to call auditlog.SetStoreFilePath to specify where
pending audit logs should be persisted.

e9324236e8 cmd/tailscale: fix default for tailscale set --accept-routes
The default values for `tailscale up` and `tailscale set` are supposed
to agree for all common flags. But they don’t for `--accept-routes`
on Windows and from the Mac OS App Store, because `tailscale up`
computes this value based on the operating system:

    user@host:~$ tailscale up --help 2>&1 | grep -A1 accept-routes
      --accept-dns, --accept-dns=false
            accept DNS configuration from the admin panel (default true)
    user@host:~$ tailscale set --help 2>&1 | grep -A1 accept-routes
      --accept-dns, --accept-dns=false
            accept DNS configuration from the admin panel

Luckily, `tailscale set` uses `ipn.MaskedPrefs`, so the default values
don’t logically matter. But someone will get the wrong idea if they
trust the `tailscale set --help` documentation.

In addition, `ipn.Prefs.RouteAll` defaults to true so it disagrees
with both of the flags above.

This patch makes `--accept-routes` use the same logic for in both
commands by hoisting the logic that was buried in `cmd/tailscale/cli`
to `ipn.Prefs.DefaultRouteAll`. Then, all three of defaults can agree.

This patch makes `--accept-dns` default to true in both commands and
also introduces `TestSetDefaultsMatchUpDefaults` to prevent any future
drift.

cmd/k8s-operator: update ProxyGroup config Secrets instead of patch (#15353)
There was a flaky failure case where renaming a TLS hostname for an
ingress might leave the old hostname dangling in tailscaled config. This
happened when the proxygroup reconciler loop had an outdated resource
version of the config Secret in its cache after the
ingress-pg-reconciler loop had very recently written it to delete the
old hostname. As the proxygroup reconciler then did a patch, there was
no conflict and it reinstated the old hostname.

This commit updates the patch to an update operation so that if the
resource version is out of date it will fail with an optimistic lock
error. It also checks for equality to reduce the likelihood that we make
the update API call in the first place, because most of the time the
proxygroup reconciler is not even making an update to the Secret in the
case that the hostname has changed.

7fac0175c0 cmd/derper, derp/derphttp: support, generate self-signed IP address certs
For people who can't use LetsEncrypt because it's banned.

Per https://github.com/tailscale/tailscale/issues/11776#issuecomment-2520955317

This does two things:

1) if you run derper with --certmode=manual and --hostname=$IP_ADDRESS
   we previously permitted, but now we also:
   * auto-generate the self-signed cert for you if it doesn't yet exist on disk
   * print out the derpmap configuration you need to use that
     self-signed cert

2) teaches derp/derphttp's derp dialer to verify the signature of
   self-signed TLS certs, if so declared in the existing
   DERPNode.CertName field, which previously existed for domain fronting,
   separating out the dial hostname from how certs are validates,
   so it's not overloaded much; that's what it was meant for.

cmd/hello: display native ipv4 (#15191)
We are soon going to start assigning shared-in nodes a CGNAT IPv4 in the Hello tailnet when necessary, the same way that normal node shares assign a new IPv4 on conflict.

But Hello wants to display the node's native IPv4, the one it uses in its own tailnet. That IPv4 isn't available anywhere in the netmap today, because it's not normally needed for anything.

We are going to start sending that native IPv4 in the peer node CapMap, only for Hello's netmap responses. This change enables Hello to display that native IPv4 instead, when available.

4f0222388a cmd,tsnet,internal/client: create internal shim to deprecated control plane API
Even after we remove the deprecated API, we will want to maintain a minimal
API for internal use, in order to avoid importing the external
tailscale.com/client/tailscale/v2 package. This shim exposes only the necessary
parts of the deprecated API for internal use, which gains us the following:

1. It removes deprecation warnings for internal use of the API.
2. It gives us an inventory of which parts we will want to keep for internal use.

6df5c8f32e various: keep tailscale connected when Always On mode is enabled on Windows
In this PR, we enable the registration of LocalBackend extensions to exclude code specific to certain
platforms or environments. We then introduce desktopSessionsExt, which is included only in Windows builds
and only if the ts_omit_desktop_sessions tag is disabled for the build. This extension tracks desktop sessions
and switches to (or remains on) the appropriate profile when a user signs in or out, locks their screen,
or disconnects a remote session.

As desktopSessionsExt requires an ipn/desktop.SessionManager, we register it with tsd.System
for the tailscaled subprocess on Windows.

We also fix a bug in the sessionWatcher implementation where it attempts to close a nil channel on stop.

cmd/containerboot: wait for consistent state on shutdown (#14263)
tailscaled's ipn package writes a collection of keys to state after
authenticating to control, but one at a time. If containerboot happens
to send a SIGTERM signal to tailscaled in the middle of writing those
keys, it may shut down with an inconsistent state Secret and never
recover. While we can't durably fix this with our current single-use
auth keys (no atomic operation to auth + write state), we can reduce
the window for this race condition by checking for partial state
before sending SIGTERM to tailscaled. Best effort only.

cmd/k8s-operator: check that cluster traffic is routed to egress ProxyGroup Pod before marking it as ready (#14792)
This change builds on top of #14436 to ensure minimum downtime during egress ProxyGroup update rollouts:

- adds a readiness gate for ProxyGroup replicas that prevents kubelet from marking
the replica Pod as ready before a corresponding readiness condition has been added
to the Pod

- adds a reconciler that reconciles egress ProxyGroup Pods and, for each that is not ready,
if cluster traffic for relevant egress endpoints is routed via this Pod- if so add the
readiness condition to allow kubelet to mark the Pod as ready.

During the sequenced StatefulSet update rollouts kubelet does not restart
a Pod before the previous replica has been updated and marked as ready, so
ensuring that a replica is not marked as ready allows to avoid a temporary
post-update situation where all replicas have been restarted, but none of the
new ones are yet set up as an endpoint for the egress service, so cluster traffic is dropped.

cmd/{k8s-operator,containerboot},kube: ensure egress ProxyGroup proxies don't terminate while cluster traffic is still routed to them (#14436)
cmd/{containerboot,k8s-operator},kube: add preshutdown hook for egress PG proxies

This change is part of work towards minimizing downtime during update
rollouts of egress ProxyGroup replicas.
This change:
- updates the containerboot health check logic to return Pod IP in headers,
if set
- always runs the health check for egress PG proxies
- updates ClusterIP Services created for PG egress endpoints to include
the health check endpoint
- implements preshutdown endpoint in proxies. The preshutdown endpoint
logic waits till, for all currently configured egress services, the ClusterIP
Service health check endpoint is no longer returned by the shutting-down Pod
(by looking at the new Pod IP header).
- ensures that kubelet is configured to call the preshutdown endpoint

This reduces the possibility that, as replicas are terminated during an update,
a replica gets terminated to which cluster traffic is still being routed via
the ClusterIP Service because kube proxy has not yet updated routig rules.
This is not a perfect check as in practice, it only checks that the kube
proxy on the node on which the proxy runs has updated rules. However, overall
this might be good enough.

The preshutdown logic is disabled if users have configured a custom health check
port via TS_LOCAL_ADDR_PORT env var. This change throws a warnign if so and in
future setting of that env var for operator proxies might be disallowed (as users
shouldn't need to configure this for a Pod directly).
This is backwards compatible with earlier proxy versions.

cmd/tailscale: add warning to help text of --force-reauth (#14778)
The warning text is adapted from https://tailscale.com/kb/1028/key-expiry#renewing-keys-for-an-expired-device .

There is already https://github.com/tailscale/tailscale/pull/7575 which presents a warning when connected over Tailscale, however the detection is done by checking SSH environment variables, which are absent within systemd's run0*. That means `--force-reauth` will happily bring down Tailscale connection, leaving the user in despair.

Changing only the help text is by no means a complete solution, but hopefully it will stop users from blindly trying it out, and motivate them to search for a proper solution.

2691b9f6be tempfork/acme: add new package for x/crypto package acme fork, move
We've been maintaining temporary dev forks of golang.org/x/crypto/{acme,ssh}
in https://github.com/tailscale/golang-x-crypto instead of using
this repo's tempfork directory as we do with other packages. The reason we were
doing that was because x/crypto/ssh depended on x/crypto/ssh/internal/poly1305
and I hadn't noticed there are forwarding wrappers already available
in x/crypto/poly1305. It also depended internal/bcrypt_pbkdf but we don't use that
so it's easy to just delete that calling code in our tempfork/ssh.

Now that our SSH changes have been upstreamed, we can soon unfork from SSH.

That leaves ACME remaining.

This change copies our tailscale/golang-x-crypto/acme code to
tempfork/acme but adds a test that our vendored copied still matches
our tailscale/golang-x-crypto repo, where we can continue to do
development work and rebases with upstream. A comment on the new test
describes the expected workflow.

While we could continue to just import & use
tailscale/golang-x-crypto/acme, it seems a bit nicer to not have that
entire-fork-of-x-crypto visible at all in our transitive deps and the
questions that invites. Showing just a fork of an ACME client is much
less scary. It does add a step to the process of hacking on the ACME
client code, but we do that approximately never anyway, and the extra
step is very incremental compared to the existing tedious steps.

f0db47338e cmd/tailscaled,util/syspolicy/source,util/winutil/gp: disallow acquiring the GP lock during service startup
In v1.78, we started acquiring the GP lock when reading policy settings. This led to a deadlock during
Tailscale installation via Group Policy Software Installation because the GP engine holds the write lock
for the duration of policy processing, which in turn waits for the installation to complete, which in turn
waits for the service to enter the running state.

In this PR, we prevent the acquisition of GP locks (aka EnterCriticalPolicySection) during service startup
and update the Windows Registry-based util/syspolicy/source.PlatformPolicyStore to handle this failure
gracefully. The GP lock is somewhat optional; it’s safe to read policy settings without it, but acquiring
the lock is recommended when reading multiple values to prevent the Group Policy engine from modifying
settings mid-read and to avoid inconsistent results.

This pulls out the Wake-on-LAN (WoL) code out into its own package
(feature/wakeonlan) that registers itself with various new hooks

Then a new build tag (ts_omit_wakeonlan) causes the package to not
even be linked in the binary.

Ohter new packages include:

   * feature: to just record which features are loaded. Future:
     dependencies between features.
   * feature/condregister: the package with all the build tags
     that tailscaled, tsnet, and the Tailscale Xcode project
     extension can empty (underscore) import to load features
     as a function of the defined build tags.

Future commits will move of our "ts_omit_foo" build tags into this

150cd30b1d ipn/ipnlocal: also use LetsEncrypt-baked-in roots for cert validation
We previously baked in the LetsEncrypt x509 root CA for our tlsdial
package.

This moves that out into a new "bakedroots" package and is now also
shared by ipn/ipnlocal's cert validation code (validCertPEM) that
decides whether it's time to fetch a new cert.

Otherwise, a machine without LetsEncrypt roots locally in its system
roots is unable to use tailscale cert/serve and fetch certs.

fcf90260ce atomicfile: use ReplaceFile on Windows so that attributes and ACLs are preserved
I moved the actual rename into separate, GOOS-specific files. On
non-Windows, we do a simple os.Rename. On Windows, we first try
ReplaceFile with a fallback to os.Rename if the target file does
not exist.

ReplaceFile is the recommended way to rename the file in this use case,
as it preserves attributes and ACLs set on the target file.

db05e83efc cmd/derper: support explicit configuration of mesh dial hosts
The --mesh-with flag now supports the specification of hostname tuples like
derp1a.tailscale.com/derp1a-vpc.tailscale.com, which instructs derp to mesh
with host 'derp1a.tailscale.com' but dial TCP connections to 'derp1a-vpc.tailscale.com'.

For backwards compatibility, --mesh-with still supports individual hostnames.

The logic which attempts to auto-discover '[host]-vpc.tailscale.com' dial hosts
has been removed.

da9965d51c cmd/viewer,types/views,various: avoid allocations in pointer field getters whenever possible
In this PR, we add a generic views.ValuePointer type that can be used as a view for pointers
to basic types and struct types that do not require deep cloning and do not have corresponding
view types. Its Get/GetOk methods return stack-allocated shallow copies of the underlying value.

We then update the cmd/viewer codegen to produce getters that return either concrete views
when available or ValuePointer views when not, for pointer fields in generated view types.
This allows us to avoid unnecessary allocations compared to returning pointers to newly
allocated shallow copies.

64ab0ddff1 cmd/tailscale/cli: only exit silently if len(args) == 0
This amends commit b7e48058c8.

That commit broke all documented ways of starting Tailscale on gokrazy:
https://gokrazy.org/packages/tailscale/ — both Option A (tailscale up)
and Option B (tailscale up --auth-key) rely on the tailscale CLI working.

I verified that the tailscale CLI just prints it help when started
without arguments, i.e. it does not stay running and is not restarted.

I verified that the tailscale CLI successfully exits when started with
tailscale up --auth-key, regardless of whether the node has joined
the tailnet yet or not.

I verified that the tailscale CLI successfully waits and exits when
started with tailscale up, as expected.

5a4148e7e8 cmd/systray: update state management and initialization
Move a number of global state vars into the Menu struct, keeping things
better encapsulated. The systray package still relies on its own global
state, so only a single Menu instance can run at a time.

Move a lot of the initialization logic out of onReady, in particular
fetching the latest tailscale state. Instead, populate the state before
calling systray.Run, which fixes a timing issue in GNOME (#14477).

This change also creates a separate bgContext for actions not tied menu
item clicks. Because we have to rebuild the entire menu regularly, we
cancel that context as needed, which can cancel subsequent updateState
calls.

Also exit cleanly on SIGINT and SIGTERM.

aa04f61d5e net/netcheck: adjust HTTPS latency check to connection time and avoid data race
The go-httpstat package has a data race when used with connections that
are performing happy-eyeballs connection setups as we are in the DERP
client. There is a long-stale PR upstream to address this, however
revisiting the purpose of this code suggests we don't really need
httpstat here.

The code populates a latency table that may be used to compare to STUN
latency, which is a lightweight RTT check. Switching out the reported
timing here to simply the request HTTP request RTT avoids the
problematic package.

cmd/k8s-operator,k8s-operator: operator integration tests (#12792)
This is the start of an integration/e2e test suite for the tailscale operator.
It currently only tests two major features, ingress proxy and API server proxy,
but we intend to expand it to cover more features over time. It also only
supports manual runs for now. We intend to integrate it into CI checks in a
separate update when we have planned how to securely provide CI with the secrets
required for connecting to a test tailnet.

06a82f416f cmd,{get-authkey,tailscale}: remove unnecessary scope qualifier from OAuth clients
OAuth clients that were used to generate an auth_key previously
specified the scope 'device'. 'device' is not an actual scope,
the real scope is 'devices'. The resulting OAuth token ended up
including all scopes from the specified OAuth client, so the code
was able to successfully create auth_keys.

It's better not to hardcode a scope here anyway, so that we have
the flexibility of changing which scope(s) are used in the future
without having to update old clients.

Since the qualifier never actually did anything, this commit simply
removes it.

cmd/k8s-operator: avoid port collision with metrics endpoint (#14185)
When the operator enables metrics on a proxy, it uses the port 9001,
and in the near future it will start using 9002 for the debug endpoint
as well. Make sure we don't choose ports from a range that includes
9001 so that we never clash. Setting TS_SOCKS5_SERVER, TS_HEALTHCHECK_ADDR_PORT,
TS_OUTBOUND_HTTP_PROXY_LISTEN, and PORT could also open arbitrary ports,
so we will need to document that users should not choose ports from the
10000-11000 range for those settings.

cmd/k8s-operator,docs/k8s: run tun mode proxies in privileged containers (#14262)
We were previously relying on unintended behaviour by runc where
all containers where by default given read/write/mknod permissions
for tun devices.
This behaviour was removed in https://github.com/opencontainers/runc/pull/3468
and released in runc 1.2.
Containerd container runtime, used by Docker and majority of Kubernetes distributions
bumped runc to 1.2 in 1.7.24 https://github.com/containerd/containerd/releases/tag/v1.7.24
thus breaking our reference tun mode Tailscale Kubernetes manifests and Kubernetes
operator proxies.

This PR changes the all Kubernetes container configs that run Tailscale in tun mode
to privileged. This should not be a breaking change because all these containers would
run in a Pod that already has a privileged init container.

cmd/containerboot: serve health on local endpoint (#14246)
* cmd/containerboot: serve health on local endpoint

We introduced stable (user) metrics in #14035, and `TS_LOCAL_ADDR_PORT`
with it. Rather than requiring users to specify a new addr/port
combination for each new local endpoint they want the container to
serve, this combines the health check endpoint onto the local addr/port
used by metrics if `TS_ENABLE_HEALTH_CHECK` is used instead of
`TS_HEALTHCHECK_ADDR_PORT`.

`TS_LOCAL_ADDR_PORT` now defaults to binding to all interfaces on 9002
so that it works more seamlessly and with less configuration in
environments other than Kubernetes, where the operator always overrides
the default anyway. In particular, listening on localhost would not be
accessible from outside the container, and many scripted container
environments do not know the IP address of the container before it's
started. Listening on all interfaces allows users to just set one env
var (`TS_ENABLE_METRICS` or `TS_ENABLE_HEALTH_CHECK`) to get a fully
functioning local endpoint they can query from outside the container.

cmd/{containerboot,k8s-operator},k8s-operator: new options to expose user metrics (#14035)
containerboot:

Adds 3 new environment variables for containerboot, `TS_LOCAL_ADDR_PORT` (default
`"${POD_IP}:9002"`), `TS_METRICS_ENABLED` (default `false`), and `TS_DEBUG_ADDR_PORT`
(default `""`), to configure metrics and debug endpoints. In a follow-up PR, the
health check endpoint will be updated to use the `TS_LOCAL_ADDR_PORT` if
`TS_HEALTHCHECK_ADDR_PORT` hasn't been set.

Users previously only had access to internal debug metrics (which are unstable
and not recommended) via passing the `--debug` flag to tailscaled, but can now
set `TS_METRICS_ENABLED=true` to expose the stable metrics documented at
https://tailscale.com/kb/1482/client-metrics at `/metrics` on the addr/port
specified by `TS_LOCAL_ADDR_PORT`.

Users can also now configure a debug endpoint more directly via the
`TS_DEBUG_ADDR_PORT` environment variable. This is not recommended for production
use, but exposes an internal set of debug metrics and pprof endpoints.

operator:

The `ProxyClass` CRD's `.spec.metrics.enable` field now enables serving the
stable user metrics documented at https://tailscale.com/kb/1482/client-metrics
at `/metrics` on the same "metrics" container port that debug metrics were
previously served on. To smooth the transition for anyone relying on the way the
operator previously consumed this field, we also _temporarily_ serve tailscaled's
internal debug metrics on the same `/debug/metrics` path as before, until 1.82.0
when debug metrics will be turned off by default even if `.spec.metrics.enable`
is set. At that point, anyone who wishes to continue using the internal debug
metrics (not recommended) will need to set the new `ProxyClass` field
`.spec.statefulSet.pod.tailscaleContainer.debug.enable`.

Users who wish to opt out of the transitional behaviour, where enabling
`.spec.metrics.enable` also enables debug metrics, can set
`.spec.statefulSet.pod.tailscaleContainer.debug.enable` to false (recommended).

Separately but related, the operator will no longer specify a host port for the
"metrics" container port definition. This caused scheduling conflicts when k8s
needs to schedule more than one proxy per node, and was not necessary for allowing
the pod's port to be exposed to prometheus scrapers.

updates more frequently than is necessary causing more restarts than is

the auth key after pods have initially authed to control. However, note
that pods will still restart on scale-up/down because of the updated set
of volumes mounted into each pod. Hopefully we can fix that in a planned

01185e436f types/result, util/lineiter: add package for a result type, use it
This adds a new generic result type (motivated by golang/go#70084) to
try it out, and uses it in the new lineutil package (replacing the old
lineread package), changing that package to return iterators:
sometimes over []byte (when the input is all in memory), but sometimes
iterators over results of []byte, if errors might happen at runtime.

In this PR, we add the tailscale syspolicy command with two subcommands: list, which displays
policy settings, and reload, which forces a reload of those settings. We also update the LocalAPI
and LocalClient to facilitate these additions.

cmd/k8s-operator,k8s-operator: add topology spread constraints to ProxyClass (#13959)
Now when we have HA for egress proxies, it makes sense to support topology
spread constraints that would allow users to define more complex
topologies of how proxy Pods need to be deployed in relation with other
Pods/across regions etc.

9545e36007 cmd/tailscale/cli: add 'tailscale metrics' command
- `tailscale metrics print`: to show metric values in console
- `tailscale metrics write`: to write metrics to a file (with a tempfile
  & rename dance, which is atomic on Unix).

Also, remove the `TS_DEBUG_USER_METRICS` envknob as we are getting
more confident in these metrics.

e815ae0ec4 util/syspolicy, ipn/ipnlocal: update syspolicy package to utilize syspolicy/rsop
In this PR, we update the syspolicy package to utilize syspolicy/rsop under the hood,
and remove syspolicy.CachingHandler, syspolicy.windowsHandler and related code
which is no longer used.

We mark the syspolicy.Handler interface and RegisterHandler/SetHandlerForTest functions
as deprecated, but keep them temporarily until they are no longer used in other repos.

We also update the package to register setting definitions for all existing policy settings
and to register the Registry-based, Windows-specific policy stores when running on Windows.

Finally, we update existing internal and external tests to use the new API and add a few more
tests and benchmarks.

c76a6e5167 derp: track client-advertised non-ideal DERP connections in more places
In f77821fd63 (released in v1.72.0), we made the client tell a DERP server
when the connection was not its ideal choice (the first node in its region).

But we didn't do anything with that information until now. This adds a
metric about how many such connections are on a given derper, and also
adds a bit to the PeerPresentFlags bitmask so watchers can identify
(and rebalance) them.
