Tom Proctor	d8a3683fdf	cmd/k8s-operator: restart ProxyGroup pods less (#14045 ) We currently annotate pods with a hash of the tailscaled config so that we can trigger pod restarts whenever it changes. However, the hash updates more frequently than is necessary causing more restarts than is necessary. This commit removes two causes; scaling up/down and removing 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 follow-up PR.

Brad Fitzpatrick	c3306bfd15	control/controlhttp/controlhttpserver: split out Accept to its own package Otherwise all the clients only using control/controlhttp for the ts2021 HTTP client were also pulling in WebSocket libraries, as the server side always needs to speak websockets, but only GOOS=js clients speak it. This doesn't yet totally remove the websocket dependency on Linux because Linux has a envknob opt-in to act like GOOS=js for manual testing and force the use of WebSockets for DERP only (not control). We can put that behind a build tag in a future change to eliminate the dep on all GOOSes.

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.

Irbe Krumina	e8bb5d1be5	cmd/{k8s-operator,containerboot},k8s-operator,kube: reconcile ExternalName Services for ProxyGroup (#13635 ) Adds a new reconciler that reconciles ExternalName Services that define a tailnet target that should be exposed to cluster workloads on a ProxyGroup's proxies. The reconciler ensures that for each such service, the config mounted to the proxies is updated with the tailnet target definition and that and EndpointSlice and ClusterIP Service are created for the service. Adds a new reconciler that ensures that as proxy Pods become ready to route traffic to a tailnet target, the EndpointSlice for the target is updated with the Pods' endpoints.

Irbe Krumina	c62b0732d2	cmd/k8s-operator: remove auth key once proxy has logged in (#13612 ) The operator creates a non-reusable auth key for each of the cluster proxies that it creates and puts in the tailscaled configfile mounted to the proxies. The proxies are always tagged, and their state is persisted in a Kubernetes Secret, so their node keys are expected to never be regenerated, so that they don't need to re-auth. Some tailnet configurations however have seen issues where the auth keys being left in the tailscaled configfile cause the proxies to end up in unauthorized state after a restart at a later point in time. Currently, we have not found a way to reproduce this issue, however this commit removes the auth key from the config once the proxy can be assumed to have logged in. If an existing, logged-in proxy is upgraded to this version, its redundant auth key will be removed from the conffile. If an existing, logged-in proxy is downgraded from this version to a previous version, it will work as before without re-issuing key as the previous code did not enforce that a key must be present.

Tom Proctor	cab2e6ea67	cmd/k8s-operator,k8s-operator: add ProxyGroup CRD (#13591 ) The ProxyGroup CRD specifies a set of N pods which will each be a tailnet device, and will have M different ingress or egress services mapped onto them. It is the mechanism for specifying how highly available proxies need to be. This commit only adds the definition, no controller loop, and so it is not currently functional. This commit also splits out TailnetDevice and RecorderTailnetDevice into separate structs because the URL field is specific to recorders, but we want a more generic struct for use in the ProxyGroup status field.

Kubectl (or whoever is the client that initiates the 'kubectl exec' session recording) sends the terminal dimensions in a resize message that the API server proxy can intercept, however that races with the first server message that we need to record. This PR ensures we wait for the terminal dimensions to be processed from the first resize message before any other data is sent, so that for all sessions with terminal attached, the header of the session recording contains the terminal dimensions and the recording can be played by tsrecorder.

Nick Khyl	961ee321e8	ipn/{ipnauth,ipnlocal,ipnserver,localapi}: start baby step toward moving access checks from the localapi.Handler to the LocalBackend Currently, we use PermitRead/PermitWrite/PermitCert permission flags to determine which operations are allowed for a LocalAPI client. These checks are performed when localapi.Handler handles a request. Additionally, certain operations (e.g., changing the serve config) requires the connected user to be a local admin. This approach is inherently racey and is subject to TOCTOU issues. We consider it to be more critical on Windows environments, which are inherently multi-user, and therefore we prevent more than one OS user from connecting and utilizing the LocalBackend at the same time. However, the same type of issues is also applicable to other platforms when switching between profiles that have different OperatorUser values in ipn.Prefs. We'd like to allow more than one Windows user to connect, but limit what they can see and do based on their access rights on the device (e.g., an local admin or not) and to the currently active LoginProfile (e.g., owner/operator or not), while preventing TOCTOU issues on Windows and other platforms. Therefore, we'd like to pass an actor from the LocalAPI to the LocalBackend to represent the user performing the operation. The LocalBackend, or the profileManager down the line, will then check the actor's access rights to perform a given operation on the device and against the current (and/or the target) profile. This PR does not change the current permission model in any way, but it introduces the concept of an actor and includes some preparatory work to pass it around. Temporarily, the ipnauth.Actor interface has methods like IsLocalSystem and IsLocalAdmin, which are only relevant to the current permission model. It also lacks methods that will actually be used in the new model. We'll be adding these gradually in the next PRs and removing the deprecated methods and the Permit* flags at the end of the transition.

Jordan Whited	df6014f1d7	net/tstun,wgengine{/netstack/gro}: refactor and re-enable gVisor GRO for Linux (#13172 ) In `2f27319baf` we disabled GRO due to a data race around concurrent calls to tstun.Wrapper.Write(). This commit refactors GRO to be thread-safe, and re-enables it on Linux. This refactor now carries a GRO type across tstun and netstack APIs with a lifetime that is scoped to a single tstun.Wrapper.Write() call. In `25f0a3fc8f` we used build tags to prevent importation of gVisor's GRO package on iOS as at the time we believed it was contributing to additional memory usage on that platform. It wasn't, so this commit simplifies and removes those build tags.
