RHBA-2021:1232 - OpenShift Container Platform 4.6.26 bug fix update

Synopsis

OpenShift Container Platform 4.6.26 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Red Hat OpenShift Container Platform release 4.6.26 is now available with updates to packages and images that fix several bugs.

Description

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 4.6.26. See the following advisory for the RPM packages for this release:

https://access.redhat.com/errata/RHBA-2021:1229

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/4.6/release_notes/ocp-4-6-release-notes.html

This update fixes the following bugs among others:

Previously, IPv6 addresses that began with leading zeros were not calculated, and those IP addresses were not assigned. With this release, the IPv6 calculation method is improved and IPv6 addresses with leading zeroes are calculated properly. (BZ#1931953)
Previously, as part of minimizing the amount of data from the pod's /run/secrets that is copied into the build container, BZ#1916897 failed to include /run/secrets/etc-pki-entitlements if it was available. As a result, entitled builds with their entitlement certificates stored on the OpenShift Container Platform host or node did not work seamlessly. With this release, the OpenShift Container Platform build image and associated pod mounts all available entitlement-related files that are in /run/secrets into the build container, and entitled builds are unable to pick up the certificates stored on the OpenShift Container Platform host or node. When running OpenShift Container Platform builds on RHCOS nodes, error messages similar to level=warning msg="Path \"/run/secrets/etc-pki-entitlement\" from \"/etc/containers/mounts.conf\" doesn't exist, skipping can be ignored. (BZ#1946363)
