Runtime

• Added garbage collection for image layers (moby/moby#40412).

Known issues

• The removal of the ipa SELinux module from the base system configuration of Red Hat Enterprise Linux 8.4 stripped container_exec_t processes inside containers of their ability to read pidfile-labeled files, including conttainer_var_run_t.

  Workaround:

  Workflows that rely on bind mounting the Docker socket in a container running on RHEL 8.4 or later should mount the socket with --security-opt=disable or an SELinux mount option, such as Z.
