Mario Minardi	d32d742af0	ipn/ipnlocal: error when trying to use exit node on unsupported platform (#13726 ) Adds logic to `checkExitNodePrefsLocked` to return an error when attempting to use exit nodes on a platform where this is not supported. This mirrors logic that was added to error out when trying to use `ssh` on an unsupported platform, and has very similar semantics.

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.

This change: - only creates the rule if it doesn't already exist - if a rule for the same dst, but different source is found, delete it - also ensures that egress proxies refresh firewall rules if the node's tailnet IP changes Updates tailscale/tailscale#13406 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	2 months ago

Irbe Krumina	096b090caf	cmd/containerboot,kube,util/linuxfw: configure kube egress proxies to route to 1+ tailnet targets (#13531 ) * cmd/containerboot,kube,util/linuxfw: configure kube egress proxies to route to 1+ tailnet targets This commit is first part of the work to allow running multiple replicas of the Kubernetes operator egress proxies per tailnet service + to allow exposing multiple tailnet services via each proxy replica. This expands the existing iptables/nftables-based proxy configuration mechanism. A proxy can now be configured to route to one or more tailnet targets via a (mounted) config file that, for each tailnet target, specifies: - the target's tailnet IP or FQDN - mappings of container ports to which cluster workloads will send traffic to tailnet target ports where the traffic should be forwarded. Example configfile contents: { "some-svc": {"tailnetTarget":{"fqdn":"foo.tailnetxyz.ts.net","ports"{"tcp:4006:80":{"protocol":"tcp","matchPort":4006,"targetPort":80},"tcp:4007:443":{"protocol":"tcp","matchPort":4007,"targetPort":443}}}} } A proxy that is configured with this config file will configure firewall rules to route cluster traffic to the tailnet targets. It will then watch the config file for updates as well as monitor relevant netmap updates and reconfigure firewall as needed. This adds a bunch of new iptables/nftables functionality to make it easier to dynamically update the firewall rules without needing to restart the proxy Pod as well as to make it easier to debug/understand the rules: - for iptables, each portmapping is a DNAT rule with a comment pointing at the 'service',i.e: -A PREROUTING ! -i tailscale0 -p tcp -m tcp --dport 4006 -m comment --comment "some-svc:tcp:4006 -> tcp:80" -j DNAT --to-destination 100.64.1.18:80 Additionally there is a SNAT rule for each tailnet target, to mask the source address. - for nftables, a separate prerouting chain is created for each tailnet target and all the portmapping rules are placed in that chain. This makes it easier to look up rules and delete services when no longer needed. (nftables allows hooking a custom chain to a prerouting hook, so no extra work is needed to ensure that the rules in the service chains are evaluated). The next steps will be to get the Kubernetes Operator to generate the configfile and ensure it is mounted to the relevant proxy nodes.

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.

Two new endpoints were added in LocalAPI to support the CLI functionality: - `/netmap`: dumps a copy of the last received network map (because the CLI shouldn't have to listen to the ipn bus for a copy) - `/dns-osconfig`: dumps the OS DNS configuration (this will be very handy for the UI clients as well, as they currently do not display this information) My plan is to implement other subcommands mentioned in tailscale/tailscale#13326, such as `query`, in later PRs.

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.
