Description Adam Kaplan 2021-03-18 14:31:24 UTC

Description of problem:

After fixing CVE-2021-3344, builds do not automatically mount entitlement keys that may be present on the node.


Version-Release number of selected component (if applicable): 4.5.33, 4.6.16, 4.7.0


How reproducible: Always


Steps to Reproduce:
1. Install OpenShift with a MachineConfig that adds entitlement keys to worker nodes
2. Create a Docker strategy BuildConfig that executes a yum install of subscription content.
3. Run a build from this BuildConfig

Actual results:

yum install of subscription content fails


Expected results:

yum install succeeds because entitlement keys are present

Comment 49 Rolfe Dlugy-Hegwer 2021-04-09 12:53:10 UTC

Supporting information for release notes:

Cause: in minimizing the amount of data from the Pod's /run/secrets copied into the build container, Bug 1916897 failed to include /run/secrets/etc-pki-entitlements if that was available.

Consequence: the cve fix then prevents entitled builds from working seamlessly if the entitlement certificates are stored on the OCP host/node

Fix: The OpenShift Build Image and associated Pod will now mount all available entitlement related files in /run/secrets into the build container

Result: entitled builds will not be able to pick up the certificates stored on the OCP host/node.  Note:  warning message like 'level=warning msg="Path \"/run/secrets/etc-pki-entitlement\" from \"/etc/containers/mounts.conf\" doesn't exist, skipping' when running OCP Builds on RHCOS nodes can be ignored.
