Previously, running `add/remove/revoke-keys` without passing any keys
would fail with an unhelpful error:
```console
$ tailscale lock revoke-keys
generation of recovery AUM failed: sending generate-recovery-aum: 500 Internal Server Error: no provided key is currently trusted
```
or
```console
$ tailscale lock revoke-keys
generation of recovery AUM failed: sending generate-recovery-aum: 500 Internal Server Error: network-lock is not active
```
Now they fail with a more useful error:
```console
$ tailscale lock revoke-keys
missing argument, expected one or more tailnet lock keys
```

* ipn/ipnlocal: warn incompatibility between no-snat-routes and exitnode
This commit adds a warning to health check when the --snat-subnet-routes=false flag for subnet router is
set alone side --advertise-exit-node=true. These two would conflict with each other and result internet-bound
traffic from peers using this exit node no masqueraded to the node's source IP and fail to route return
packets back. The described combination is not valid until we figure out a way to separate exitnode masquerade rule and skip it for subnet routes.

By polling RTM_GETSTATS via netlink. RTM_GETSTATS is a relatively
efficient and targeted (single device) polling method available since
Linux v4.7.
The tundevstats "feature" can be extended to other platforms in the
future, and it's trivial to add new rtnl_link_stats64 counters on
Linux.

Replace byte-at-a-time ReadByte loops with Peek+Discard in the DERP
read path. Peek returns a slice into bufio's internal buffer without
allocating, and Discard advances the read pointer without copying.
Introduce util/bufiox with a BufferedReader interface and ReadFull
helper that uses Peek+copy+Discard as an allocation-free alternative
to io.ReadFull.
- derp.ReadFrameHeader: replace 5× ReadByte with Peek(5)+Discard(5),
reading the frame type and length directly from the peeked slice.
Remove now-unused readUint32 helper.

key (#18606)
When a client starts up without being able to connect to control, it
sends its discoKey to other nodes it wants to communicate with over
TSMP. This disco key will be a newer key than the one control knows
about.
If the client that can connect to control gets a full netmap, ensure
that the disco key for the node not connected to control is not
overwritten with the stale key control knows about.
This is implemented through keeping track of mapSession and use that for
the discokey injection if it is available. This ensures that we are not
constantly resetting the wireguard connection when getting the wrong
keys from control.
This is implemented as:
- If the key is received via TSMP:
- Set lastSeen for the peer to now()
- Set online for the peer to false
- When processing new keys, only accept keys where either:
- Peer is online
- lastSeen is newer than existing last seen
If mapSession is not available, as in we are not yet connected to
control, punt down the disco key injection to magicsock.
Ideally, we will want to have mapSession be long lived at some point in
the near future so we only need to inject keys in one location and then
also use that for testing and loading the cache, but that is a yak for
another PR.

Currently IP forwarding health check is done on sending MapRequests.
Move ip forwarding to the health service to gain the benefits
of the health tracker and perodic monitoring out of band from
the MapRequest path. ipnlocal now provides a closure to
the health service to provide the check if forwarding is broken.
Removed `skipIPForwardingCheck` from controlclient/direct.go,
it wasn't being used as the comments describe it, that check
has moved to ipnlocal for the closure to the health tracker.

The e2e ingress test was very occasionally flaky. On looking at operator
logs from one failure, you can see the default ProxyClass was not ready
before the first reconcile loop for the exposed Service. The ProxyClass
became ready soon after, but no additional reconciles were triggered for
the exposed Service because we only triggered reconciles for Services
that explicitly named their ProxyClass.
This change adds additional list API calls for when it's the default
ProxyClass that's been updated in order to catch Services that use it by
default. It also adds indexes for the fields we need to search on to
ensure the list is efficient.

Adds logic for containerboot to signal that it can't auth, so the
operator can reissue a new auth key. This only applies when running with
a config file and with a kube state store.
If the operator sees reissue_authkey in a state Secret, it will create a
new auth key iff the config has no auth key or its auth key matches the
value of reissue_authkey from the state Secret. This is to ensure we
don't reissue auth keys in a tight loop if the proxy is slow to start or
failing for some other reason. The reissue logic also uses a burstable
rate limiter to ensure there's no way a terminally misconfigured
or buggy operator can automatically generate new auth keys in a tight loop.
Additional implementation details (ChaosInTheCRD):
- Added `ipn.NotifyInitialHealthState` to ipn watcher, to ensure that
`n.Health` is populated when notify's are returned.
- on auth failure, containerboot:
- Disconnects from control server
- Sets reissue_authkey marker in state Secret with the failing key
- Polls config file for new auth key (10 minute timeout)
- Restarts after receiving new key to apply it
- modified operator's reissue logic slightly:
- Deletes old device from tailnet before creating new key
- Rate limiting: 1 key per 30s with initial burst equal to replica count
- In-flight tracking (authKeyReissuing map) prevents duplicate API calls
across reconcile loops

PR #18860 adds firewall rules in the mangle table to save outbound packet
marks to conntrack and restore them on reply packets before the routing
decision. When reply packets have their marks restored, the kernel uses
the correct routing table (based on the mark) and the packets pass the
rp_filter check.
This makes the risk check and reverse path filtering warnings unnecessary.

This commit implements a reconciler for the new `ProxyGroupPolicy`
custom resource. When created, all `ProxyGroupPolicy` resources
within the same namespace are merged into two `ValidatingAdmissionPolicy`
resources, one for egress and one for ingress.
These policies use CEL expressions to limit the usage of the
"tailscale.com/proxy-group" annotation on `Service` and `Ingress`
resources on create & update.
Included here is also a new e2e test that ensures that resources that
violate the policy return an error on creation, and that once the
policy is changed to allow them they can be created.

This commit adds a new custom resource definition to the kubernetes
operator named `ProxyGroupPolicy`. This resource is namespace scoped
and is used as an allow list for which `ProxyGroup` resources can be
used within its namespace.
The `spec` contains two fields, `ingress` and `egress`. These should
contain the names of `ProxyGroup` resources to denote which can be
used as values in the `tailscale.com/proxy-group` annotation within
`Service` and `Ingress` resources.
The intention is for these policies to be merged within a namespace and
produce a `ValidatingAdmissionPolicy` and `ValidatingAdmissionPolicyBinding`
for both ingress and egress that prevents users from using names of
`ProxyGroup` resources in those annotations.
