Security Profiles Operator release notes

Security Profiles Operator (SPO) now automatically selects the appropriate selinuxd image for RHEL 8- and 9-based RHCOS systems.

You can now enable memory optimization inside of an spod daemon. For more information, see Enabling memory optimization in the spod daemon.

The daemon resource requirements are now configurable. For more information, see Customizing daemon resource requirements.

The priority class name is now configurable in the spod configuration. For more information, see Setting a custom priority class name for the spod daemon pod.

The default nginx-1.19.1 seccomp profile is now removed from the Security Profiles Operator deployment.

Previously, a Security Profiles Operator (SPO) SELinux policy did not inherit low-level policy definitions from the container template. If you selected another template, such as net_container, the policy would not work because it required low-level policy definitions that only existed in the container template. This issue occurred when the SPO SELinux policy attempted to translate SELinux policies from the SPO custom format to the Common Intermediate Language (CIL) format. With this update, the container template appends to any SELinux policies that require translation from SPO to CIL. Additionally, the SPO SELinux policy can inherit low-level policy definitions from any supported policy template. (OCPBUGS-12879)

When uninstalling the Security Profiles Operator, the MutatingWebhookConfiguration object is not deleted and must be manually removed. As a workaround, delete the MutatingWebhookConfiguration object after uninstalling the Security Profiles Operator. These steps are defined in Uninstalling the Security Profiles Operator.
