1.2.5. Fixed issues

The following issues have been resolved in the current release:

  • OSSM-6331 Previously, the smcp.general.logging.componentLevels spec accepted invalid LogLevel values, and the ServiceMeshControlPlane resource was still created. Now, the terminal shows an error message if an invalid value is used, and the control plane is not created.
  • OSSM-6290 Previously, the Project filter of the Istio Config list page did not work correctly. All istio config items were displayed from all namespaces even if you selected a specific project from the drop-down menu. Now, only the istio config items that belong to the selected project in the filter dropdown are displayed.
  • OSSM-6298 Previously, when you clicked an item reference within the OpenShift Service Mesh Console (OSSMC) plugin, the console sometimes performed multiple redirects before opening the desired page. As a result, navigating back to the previous page that was open in the console caused your web browser to open the wrong page. Now, these redirects do not occur, and clicking Back in a web browser brings you to the correct page.
  • OSSM-6299 Previously, in OpenShift Container Platform 4.15, when you clicked the Node graph menu option of any node menu within the traffic graph, the node graph was not displayed. Instead, the page refreshed with the same traffic graph. Now, clicking the Node graph menu option correctly displays the node graph.

The following issues have been resolved in previous releases:

1.2.5.1. Service Mesh fixed issues
링크 복사

  • OSSM-6177 Previously, when validation messages were enabled in the ServiceMeshControlPlane (SMCP), the istiod crashed continuously unless GatewayAPI support was enabled. Now, when validation messages are enabled but GatewayAPI support is not, the istiod does not continuously crash.

  • OSSM-6163 Resolves the following issues:

    • Previously, an unstable Prometheus image was included in the Service Mesh control plane (SMCP) v2.5, and users were not able to access the Prometheus dashboard. Now, in the Service Mesh operator 2.5.1, the Prometheus image has been updated.
    • Previously, in the Service Mesh control plane (SMCP), a Grafana data source was not able to set Basic authentication password automatically and users were not able to view metrics from Prometheus in Grafana mesh dashboards. Now, a Grafana data source password is configured under the secureJsonData field. Metrics are displayed correctly in dashboards.
  • OSSM-6148 Previously, the OpenShift Service Mesh Console (OSSMC) plugin did not respond when the user clicked any option in the menu of any node on the Traffic Graph page. Now, the plugin responds to the selected option in the menu by redirecting to the corresponding details page.
  • OSSM-6099 Previously, the OpenShift Service Mesh Console (OSSMC) plugin failed to load correctly in an IPv6 cluster. Now, the OSSMC plugin configuration has been modified to ensure proper loading in an IPv6 cluster.
  • OSSM-5960 Previously, the OpenShift Service Mesh Console (OSSMC) plugin did not display notification messages such as backend errors or Istio validations. Now, these notifications are displayed correctly at the top of the plugin page.
  • OSSM-5959 Previously, the OpenShift Service Mesh Console (OSSMC) plugin did not display TLS and Istio certification information in the Overview page. Now, this information is displayed correctly.
  • OSSM-5902 Previously, the OpenShift Service Mesh Console (OSSMC) plugin redirected to a "Not Found Page" error when the user clicked the Istio config health symbol on the Overview page. Now, the plugin redirects to the correct Istio config details page.
  • OSSM-5541 Previously, an Istio operator pod might keep waiting for the leader lease in some restart conditions. Now, the leader election implementation has been enhanced to avoid this issue.

  • OSSM-1397 Previously, if you removed the maistra.io/member-of label from a namespace, the Service Mesh Operator did not automatically reapply the label to the namespace. As a result, sidecar injection did not work in the namespace.

    The Operator would reapply the label to the namespace when you made changes to the ServiceMeshMember object, which triggered the reconciliation of this member object.

    Now, any change to the namespace also triggers the member object reconciliation.

  • OSSM-3647 Previously, in the Service Mesh control plane (SMCP) v2.2 (Istio 1.12), WasmPlugins were applied only to inbound listeners. Since SMCP v2.3 (Istio 1.14), WasmPlugins have been applied to inbound and outbound listeners by default, which introduced regression for users of the 3scale WasmPlugin. Now, the environment variable APPLY_WASM_PLUGINS_TO_INBOUND_ONLY is added, which allows safe migration from SMCP v2.2 to v2.3 and v2.4.

    The following setting should be added to the SMCP config: 

    spec:
  runtime:
    components:
      pilot:
        container:
          env:
            APPLY_WASM_PLUGINS_TO_INBOUND_ONLY: "true"

    To ensure safe migration, perform the following steps:

    1. Set APPLY_WASM_PLUGINS_TO_INBOUND_ONLY in SMCP v2.2.
    2. Upgrade to 2.4.
    3. Set spec.match[].mode: SERVER in WasmPlugins.
    4. Remove the previously-added environment variable.
  • OSSM-4851 Previously, an error occurred in the operator deploying new pods in a namespace scoped inside the mesh when runAsGroup, runAsUser, or fsGroup parameters were nil. Now, a yaml validation has been added to avoid the nil value.
  • OSSM-3771 Previously, OpenShift routes could not be disabled for additional ingress gateways defined in a Service Mesh Control Plane (SMCP). Now, a routeConfig block can be added to each additionalIngress gateway so the creation of OpenShift routes can be enabled or disabled for each gateway.

  • OSSM-4197 Previously, if you deployed a v2.2 or v2.1 of the 'ServiceMeshControlPlane' resource, the /etc/cni/multus/net.d/ directory was not created. As a result, the istio-cni pod failed to become ready, and the istio-cni pods log contained the following message: 

    $ error   Installer exits with open /host/etc/cni/multus/net.d/v2-2-istio-cni.kubeconfig.tmp.841118073: no such file or directory

    Now, if you deploy a v2.2 or v2.1 of the 'ServiceMeshControlPlane' resource, the /etc/cni/multus/net.d/ directory is created, and the istio-cni pod becomes ready.

  • OSSM-3993 Previously, Kiali only supported OpenShift OAuth via a proxy on the standard HTTPS port of 443. Now, Kiali supports OpenShift OAuth over a non-standard HTTPS port. To enable the port, you must set the spec.server.web_port field to the proxy’s non-standard HTTPS port in the Kiali CR.
  • OSSM-3936 Previously, the values for the injection_label_rev and injection_label_name attributes were hardcoded. This prevented custom configurations from taking effect in the Kiali Custom Resource Definition (CRD). Now, the attribute values are not hardcoded. You can customize the values for the injection_label_rev and injection_label_name attributes in the spec.istio_labels specification.
  • OSSM-3644 Previously, the federation egress-gateway received the wrong update of network gateway endpoints, causing extra endpoint entries. Now, the federation-egress gateway has been updated on the server side so it receives the correct network gateway endpoints.
  • OSSM-3595 Previously, the istio-cni plugin sometimes failed on RHEL because SELinux did not allow the utility iptables-restore to open files in the /tmp directory. Now, SELinux passes iptables-restore via stdin input stream instead of via a file.
  • OSSM-3586 Previously, Istio proxies were slow to start when Google Cloud metadata servers were not available. When you upgrade to Istio 1.14.6, Istio proxies start as expected on Google Cloud, even if metadata servers are not available.
  • OSSM-3025 Istiod sometimes fails to become ready. Sometimes, when a mesh contained many member namespaces, the Istiod pod did not become ready due to a deadlock within Istiod. The deadlock is now resolved and the pod now starts as expected.
  • OSSM-2493 Default nodeSelector and tolerations in SMCP not passed to Kiali. The nodeSelector and tolerations you add to SMCP.spec.runtime.defaults are now passed to the Kiali resource.
  • OSSM-2492 Default tolerations in SMCP not passed to Jaeger. The nodeSelector and tolerations you add to SMCP.spec.runtime.defaults are now passed to the Jaeger resource.
  • OSSM-2374 If you deleted one of the ServiceMeshMember resources, then the Service Mesh operator deleted the ServiceMeshMemberRoll. While this is expected behavior when you delete the last ServiceMeshMember, the operator should not delete the ServiceMeshMemberRoll if it contains any members in addition to the one that was deleted. This issue is now fixed and the operator only deletes the ServiceMeshMemberRoll when the last ServiceMeshMember resource is deleted.

  • OSSM-2373 Error trying to get OAuth metadata when logging in. To fetch the cluster version, the system:anonymous account is used. With the cluster’s default bundled ClusterRoles and ClusterRoleBinding, the anonymous account can fetch the version correctly. If the system:anonymous account loses its privileges to fetch the cluster version, OpenShift authentication becomes unusable.

    This is fixed by using the Kiali SA to fetch the cluster version. This also allows for improved security on the cluster.

  • OSSM-2371 Despite Kiali being configured as "view-only," a user can change the proxy logging level via the Workload details' Logs tab’s kebab menu. This issue has been fixed so the options under "Set Proxy Log Level" are disabled when Kiali is configured as "view-only."
  • OSSM-2344 Restarting Istiod causes Kiali to flood CRI-O with port-forward requests. This issue occurred when Kiali could not connect to Istiod and Kiali simultaneously issued a large number of requests to istiod. Kiali now limits the number of requests it sends to istiod.
  • OSSM-2335 Dragging the mouse pointer over the Traces scatterchart plot sometimes caused the Kiali console to stop responding due to concurrent backend requests.

  • OSSM-2221 Previously, gateway injection in the ServiceMeshControlPlane namespace was not possible because the ignore-namespace label was applied to the namespace by default.

    When creating a v2.4 control plane, the namespace no longer has the ignore-namespace label applied, and gateway injection is possible.

    In the following example, the oc label command removes the ignore-namespace label from a namespace in an existing deployment: 

    $ oc label namespace istio-system maistra.io/ignore-namespace-

    where:

    istio_system
    Specified the name of the ServiceMeshControlPlane namespace.

  • OSSM-2053 Using Red Hat OpenShift Service Mesh Operator 2.2 or 2.3, during SMCP reconciliation, the SMMR controller removed the member namespaces from SMMR.status.configuredMembers. This caused the services in the member namespaces to become unavailable for a few moments.

    Using Red Hat OpenShift Service Mesh Operator 2.2 or 2.3, the SMMR controller no longer removes the namespaces from SMMR.status.configuredMembers. Instead, the controller adds the namespaces to SMMR.status.pendingMembers to indicate that they are not up-to-date. During reconciliation, as each namespace synchronizes with the SMCP, the namespace is automatically removed from SMMR.status.pendingMembers.

  • OSSM-1962 Use EndpointSlices in federation controller. The federation controller now uses EndpointSlices, which improves scalability and performance in large deployments. The PILOT_USE_ENDPOINT_SLICE flag is enabled by default. Disabling the flag prevents use of federation deployments.
  • OSSM-1668 A new field spec.security.jwksResolverCA was added to the Version 2.1 SMCP but was missing in the 2.2.0 and 2.2.1 releases. When upgrading from an Operator version where this field was present to an Operator version that was missing this field, the .spec.security.jwksResolverCA field was not available in the SMCP.
  • OSSM-1325 istiod pod crashes and displays the following error message: fatal error: concurrent map iteration and map write.

  • OSSM-1211 Configuring Federated service meshes for failover does not work as expected.

    The Istiod pilot log displays the following error: envoy connection [C289] TLS error: 337047686:SSL routines:tls_process_server_certificate:certificate verify failed

  • OSSM-1099 The Kiali console displayed the message Sorry, there was a problem. Try a refresh or navigate to a different page.
  • OSSM-1074 Pod annotations defined in SMCP are not injected in the pods.
  • OSSM-999 Kiali retention did not work as expected. Calendar times were greyed out in the dashboard graph.
  • OSSM-797 Kiali Operator pod generates CreateContainerConfigError while installing or updating the operator.
  • OSSM-722 Namespace starting with kube is hidden from Kiali.
  • OSSM-569 There is no CPU memory limit for the Prometheus istio-proxy container. The Prometheus istio-proxy sidecar now uses the resource limits defined in spec.proxy.runtime.container.
  • OSSM-535 Support validationMessages in SMCP. The ValidationMessages field in the Service Mesh Control Plane can now be set to True. This writes a log for the status of the resources, which can be helpful when troubleshooting problems.
  • OSSM-449 VirtualService and Service causes an error "Only unique values for domains are permitted. Duplicate entry of domain."
  • OSSM-419 Namespaces with similar names will all show in Kiali namespace list, even though namespaces may not be defined in Service Mesh Member Role.
  • OSSM-296 When adding health configuration to the Kiali custom resource (CR) is it not being replicated to the Kiali configmap.
  • OSSM-291 In the Kiali console, on the Applications, Services, and Workloads pages, the "Remove Label from Filters" function is not working.
  • OSSM-289 In the Kiali console, on the Service Details pages for the 'istio-ingressgateway' and 'jaeger-query' services there are no Traces being displayed. The traces exist in Jaeger.
  • OSSM-287 In the Kiali console there are no traces being displayed on the Graph Service.

  • OSSM-285 When trying to access the Kiali console, receive the following error message "Error trying to get OAuth Metadata".

    Workaround: Restart the Kiali pod.

  • MAISTRA-2735 The resources that the Service Mesh Operator deletes when reconciling the SMCP changed in Red Hat OpenShift Service Mesh version 2.1. Previously, the Operator deleted a resource with the following labels:

    • maistra.io/owner
    • app.kubernetes.io/version

    Now, the Operator ignores resources that does not also include the app.kubernetes.io/managed-by=maistra-istio-operator label. If you create your own resources, you should not add the app.kubernetes.io/managed-by=maistra-istio-operator label to them.

  • MAISTRA-2687 Red Hat OpenShift Service Mesh 2.1 federation gateway does not send the full certificate chain when using external certificates. The Service Mesh federation egress gateway only sends the client certificate. Because the federation ingress gateway only knows about the root certificate, it cannot verify the client certificate unless you add the root certificate to the federation import ConfigMap.
  • MAISTRA-2635 Replace deprecated Kubernetes API. To remain compatible with OpenShift Container Platform 4.8, the apiextensions.k8s.io/v1beta1 API was deprecated as of Red Hat OpenShift Service Mesh 2.0.8.
  • MAISTRA-2631 The WASM feature is not working because podman is failing due to nsenter binary not being present. Red Hat OpenShift Service Mesh generates the following error message: Error: error configuring CNI network plugin exec: "nsenter": executable file not found in $PATH. The container image now contains nsenter and WASM works as expected.
  • MAISTRA-2534 When istiod attempted to fetch the JWKS for an issuer specified in a JWT rule, the issuer service responded with a 502. This prevented the proxy container from becoming ready and caused deployments to hang. The fix for the community bug has been included in the Service Mesh 2.0.7 release.

  • MAISTRA-2411 When the Operator creates a new ingress gateway using spec.gateways.additionaIngress in the ServiceMeshControlPlane, Operator is not creating a NetworkPolicy for the additional ingress gateway like it does for the default istio-ingressgateway. This is causing a 503 response from the route of the new gateway.

    Workaround: Manually create the NetworkPolicy in the istio-system namespace.

  • MAISTRA-2401 CVE-2021-3586 servicemesh-operator: NetworkPolicy resources incorrectly specified ports for ingress resources. The NetworkPolicy resources installed for Red Hat OpenShift Service Mesh did not properly specify which ports could be accessed. This allowed access to all ports on these resources from any pod. Network policies applied to the following resources are affected:

    • Galley
    • Grafana
    • Istiod
    • Jaeger
    • Kiali
    • Prometheus
    • Sidecar injector
  • MAISTRA-2378 When the cluster is configured to use OpenShift SDN with ovs-multitenant and the mesh contains a large number of namespaces (200+), the OpenShift Container Platform networking plugin is unable to configure the namespaces quickly. Service Mesh times out causing namespaces to be continuously dropped from the service mesh and then reenlisted.
  • MAISTRA-2370 Handle tombstones in listerInformer. The updated cache codebase was not handling tombstones when translating the events from the namespace caches to the aggregated cache, leading to a panic in the go routine.

  • MAISTRA-2117 Add optional ConfigMap mount to operator. The CSV now contains an optional ConfigMap volume mount, which mounts the smcp-templates ConfigMap if it exists. If the smcp-templates ConfigMap does not exist, the mounted directory is empty. When you create the ConfigMap, the directory is populated with the entries from the ConfigMap and can be referenced in SMCP.spec.profiles. No restart of the Service Mesh operator is required.

    Customers using the 2.0 operator with a modified CSV to mount the smcp-templates ConfigMap can upgrade to Red Hat OpenShift Service Mesh 2.1. After upgrading, you can continue using an existing ConfigMap, and the profiles it contains, without editing the CSV. Customers that previously used ConfigMap with a different name will either have to rename the ConfigMap or update the CSV after upgrading.

  • MAISTRA-2010 AuthorizationPolicy does not support request.regex.headers field. The validatingwebhook rejects any AuthorizationPolicy with the field, and even if you disable that, Pilot tries to validate it using the same code, and it does not work.

  • MAISTRA-1979 Migration to 2.0 The conversion webhook drops the following important fields when converting SMCP.status from v2 to v1:

    • conditions
    • components
    • observedGeneration

    • annotations

      Upgrading the operator to 2.0 might break client tools that read the SMCP status using the maistra.io/v1 version of the resource.

      This also causes the READY and STATUS columns to be empty when you run oc get servicemeshcontrolplanes.v1.maistra.io.

  • MAISTRA-1947 Technology Preview Updates to ServiceMeshExtensions are not applied.

    Workaround: Remove and recreate the ServiceMeshExtensions.

  • MAISTRA-1983 Migration to 2.0 Upgrading to 2.0.0 with an existing invalid ServiceMeshControlPlane cannot easily be repaired. The invalid items in the ServiceMeshControlPlane resource caused an unrecoverable error. The fix makes the errors recoverable. You can delete the invalid resource and replace it with a new one or edit the resource to fix the errors. For more information about editing your resource, see [Configuring the Red Hat OpenShift Service Mesh installation].
  • MAISTRA-1502 As a result of CVEs fixes in version 1.0.10, the Istio dashboards are not available from the Home Dashboard menu in Grafana. To access the Istio dashboards, click the Dashboard menu in the navigation panel and select the Manage tab.
  • MAISTRA-1399 Red Hat OpenShift Service Mesh no longer prevents you from installing unsupported CNI protocols. The supported network configurations has not changed.
  • MAISTRA-1089 Migration to 2.0 Gateways created in a non-control plane namespace are automatically deleted. After removing the gateway definition from the SMCP spec, you need to manually delete these resources.

  • MAISTRA-858 The following Envoy log messages describing deprecated options and configurations associated with Istio 1.1.x are expected:

    • [2019-06-03 07:03:28.943][19][warning][misc] [external/envoy/source/common/protobuf/utility.cc:129] Using deprecated option 'envoy.api.v2.listener.Filter.config'. This configuration will be removed from Envoy soon.
    • [2019-08-12 22:12:59.001][13][warning][misc] [external/envoy/source/common/protobuf/utility.cc:174] Using deprecated option 'envoy.api.v2.Listener.use_original_dst' from file lds.proto. This configuration will be removed from Envoy soon.

  • MAISTRA-806 Evicted Istio Operator Pod causes mesh and CNI not to deploy.

    Workaround: If the istio-operator pod is evicted while deploying the control pane, delete the evicted istio-operator pod.

  • MAISTRA-681 When the Service Mesh control plane has many namespaces, it can lead to performance issues.
  • MAISTRA-193 Unexpected console info messages are visible when health checking is enabled for citadel.
  • Bugzilla 1821432 The toggle controls in OpenShift Container Platform Custom Resource details page does not update the CR correctly. UI Toggle controls in the Service Mesh Control Plane (SMCP) Overview page in the OpenShift Container Platform web console sometimes updates the wrong field in the resource. To update a SMCP, edit the YAML content directly or update the resource from the command line instead of clicking the toggle controls.
