Percy Wegmann	2e95313b8b	ssh,tempfork/gliderlabs/ssh: replace github.com/tailscale/golang-x-crypto/ssh with golang.org/x/crypto/ssh The upstream crypto package now supports sending banners at any time during authentication, so the Tailscale fork of crypto/ssh is no longer necessary. github.com/tailscale/golang-x-crypto is still needed for some custom ACME autocert functionality. tempfork/gliderlabs is still necessary because of a few other customizations, mostly related to TTY handling. Originally implemented in `46fd4e58a2`, which was reverted in `b60f6b849a` to keep the change out of v1.80. Updates #8593 Signed-off-by: Percy Wegmann <percy@tailscale.com>	10 months ago

Irbe Krumina	3f39211f98	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.

Irbe Krumina	b406f209c3	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. Updates tailscale/tailscale#14326 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	10 months ago

Brad Fitzpatrick	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.

James Tucker	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.

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.

Tom Proctor	74d4652144	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.

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.

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.

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.

Benchmarks show substantial improvement through a wide range of RTT and loss conditions, sometimes as high as 5x. The iperf3 results below demonstrate the effect of this commit between two Linux computers with i5-12400 CPUs. There is roughly ~13us of round trip latency between them.

Note that even with `PreferDualStack` set, testing a dual-stack GKE cluster with the default DNS setup of kube-dns did not correctly set both A and AAAA records for the headless service, and instead only did so when switching the cluster DNS to Cloud DNS. For both IPv4 and IPv6 to work simultaneously in a dual-stack cluster, we require headless services to return both A and AAAA records. If the host doesn't support IPv6 but the FQDN specified only has IPv6 addresses available, containerboot will exit with error code 1 and an error message because there is no viable egress route.

This commit adds functionality to automatically populate DNS records for the in-cluster ts.net nameserver to allow cluster workloads to resolve MagicDNS names associated with operator's proxies. The records are created as follows: * For tailscale Ingress proxies there will be a record mapping the MagicDNS name of the Ingress device and each proxy Pod's IP address. * For cluster egress proxies, configured via tailscale.com/tailnet-fqdn annotation, there will be a record for each proxy Pod, mapping the MagicDNS name of the exposed tailnet workload to the proxy Pod's IP. No records will be created for any other proxy types. Records will only be created if users have configured the operator to deploy an in-cluster ts.net nameserver by applying tailscale.com/v1alpha1.DNSConfig. It is user's responsibility to add the ts.net nameserver as a stub nameserver for ts.net DNS names. https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/#configuration-of-stub-domain-and-upstream-nameserver-using-coredns https://cloud.google.com/kubernetes-engine/docs/how-to/kube-dns#upstream_nameservers See also https://github.com/tailscale/tailscale/pull/11017 Updates tailscale/tailscale#10499 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	2 years ago

Containerboot will periodically (every 10 minutes) attempt to resolve the DNS name and ensure that all traffic sent to the node's tailnet IP gets forwarded to the resolved backend IP addresses. Currently: - if the firewall mode is iptables, traffic will be load balanced accross the backend IP addresses using round robin.

Irbe Krumina	5bd19fd3e3	cmd/k8s-operator,k8s-operator: proxy configuration mechanism via a new ProxyClass custom resource (#11074 ) * cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource. ProxyClass custom resource can be used to specify customizations for the proxy resources created by the operator. Add a reconciler that validates ProxyClass resources and sets a Ready condition to True or False with a corresponding reason and message. This is required because some fields (labels and annotations) require complex validations that cannot be performed at custom resource apply time. Reconcilers that use the ProxyClass to configure proxy resources are expected to verify that the ProxyClass is Ready and not proceed with resource creation if configuration from a ProxyClass that is not yet Ready is required. If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet. If a tailscale Ingress has a tailscale.com/proxy-class annotation and the referenced ProxyClass custom resource is available and Ready, apply configuration from the ProxyClass to the proxy resources that will be created for the Ingress. Add a new .proxyClass field to the Connector spec. If connector.spec.proxyClass is set to a ProxyClass that is available and Ready, apply configuration from the ProxyClass to the proxy resources created for the Connector. Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml.

Irbe Krumina	a6cc2fdc3e	cmd/{containerboot,k8s-operator/deploy/manifests}: optionally allow proxying cluster traffic to a cluster target via ingress proxy (#11036 ) * cmd/containerboot,cmd/k8s-operator/deploy/manifests: optionally forward cluster traffic via ingress proxy. If a tailscale Ingress has tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation, configure the associated ingress proxy to have its tailscale serve proxy to listen on Pod's IP address. This ensures that cluster traffic too can be forwarded via this proxy to the ingress backend(s). In containerboot, if EXPERIMENTAL_PROXY_CLUSTER_TRAFFIC_VIA_INGRESS is set to true and the node is Kubernetes operator ingress proxy configured via Ingress, make sure that traffic from within the cluster can be proxied to the ingress target.
