Brad Fitzpatrick	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.

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	9bd158cc09	cmd/containerboot,util/linuxfw: create a SNAT rule for dst/src only once, clean up if needed (#13658 ) The AddSNATRuleForDst rule was adding a new rule each time it was called including: - if a rule already existed - if a rule matching the destination, but with different desired source already existed This was causing issues especially for the in-progress egress HA proxies work, where the rules are now refreshed more frequently, so more redundant rules were being created. 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.
