Description Zvonko Kosic 2021-06-16 11:57:17 UTC
+++ This bug was initially created as a clone of Bug #1972676 +++

In RHEL 8, when a kernel module is loaded, the kernel checks the signature of the module against the public X.509 keys from the kernel system keyring (.builtin_trusted_keys) and the kernel platform keyring (.platform). The .platform keyring contains keys from third-party platform providers and custom public keys. The keys from the kernel system .blacklist keyring are excluded from verification.

Additional tools are: yum -y install openssl mokutil keyutils

Verified in build: 4.9.0-0.nightly-2021-06-21-131605

1. Go to the OpenShift release nightly build page for the nightly build, click "Download the installer," and then click "release.txt."


2. Search for "driver-toolkit" and pull the corresponding image to your dev machine with the command:
podman pull --authfile /path/to/pullsecret <openshift_release_repo>/<corresponding_image_to_your_dev_machine>


3. Enter the following command from the terminal:
podman run <image_from_previous_step> dnf list installed | grep <string>


=====================================
Output from the command in step #3:

openssl
openssl.x86_64                                1:1.1.1g-15.el8_3                    @rhel-8-baseos-rpms-x86_64
