RHBA-2021:0678 - Bug Fix Advisory

标题

Red Hat OpenShift Container Platform release 4.7.1 is now available with
updates to packages and images that fix several bugs.

描述

Red Hat OpenShift Container Platform is Red Hat's cloud computing
Kubernetes application platform solution designed for on-premise or private
cloud deployments.

This advisory contains the container images for Red Hat OpenShift Container
Platform 4.7.1. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHBA-2020:0677

Space precludes documenting all of the container images in this advisory.
See the following Release Notes documentation, which will be updated
shortly for this release, for details about these changes:

https://docs.openshift.com/container-platform/4.7/release_notes/ocp-4-7-release-notes.html

This update fixes the following bugs among others:

• Previously, the SSH public key validation was not applied when using the `generate ISO` API. Consequently, malformed SSH public keys were accepted without returning an error, which would eventually cause failures during cluster installation. This update applies the same SSH public key when generating an ISO. As a result, a malformed SSH public key is now rejected with an error message. (BZ#1911803)
• Previously, exposing the default Ingress Controller via an external load balancer redirected all HTTP traffic to HTTPS. Consequently, canary endpoint checks performed by the Ingress Operator would fail, which would cause the Ingress cluster to become degraded. This update converts the cleartext canary route to an edge encrypted route. As a result, the canary route now works when non-secure traffic is redirected by the load balancer. (BZ#1932649)
• Previously, overlapping IPV6 subnets for different NICs would result in a failed deployment of the Keepalived configuration. For example:

`Interface A subnet: 1001:db8::/120`
`Interface B subnet: 1001:db8::f00/120`
`VIP address 1001:db8::64`

This update selects the NIC whose address is connected with the VIP address. As a result, the correct interface is selected for the Keepalived configuration. (BZ#1905233)

• Previously, CDI tests used the dev branch of CDI, but would fail on the latest dev version of CDI. This update locks the test environment to use a stable version of CDI, which allows CDI tests to pass. (BZ#1926830)
• The SR-IOV device plug-in does not allow VFIO devices on the nodes to be exposed as resources. This results in DPDK workloads being blocked on Intel devices. It is recommended that SR-IOV customers should not upgrade to OpenShift Container Platform 4.7 until this issue is fixed. (BZ#1930469)

All OpenShift Container Platform 4.7 users are advised to upgrade to these
updated packages and images when they are available in the appropriate
release channel. To check for available updates, use the OpenShift Console
or the CLI oc command. Instructions for upgrading a cluster are available
