RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Github osbuild osbuild pull 598 0 None open stages/oci-archive: do not include selinux labels 2021-03-01 18:41:05 UTC

Description Christian Kellner 2021-03-01 16:56:25 UTC
Currently the org.osbuild.oci-archive assembler/stage pass --selinux to the tar file which results in the SELinux labels being included in the archive. This labels will end up on disc when using podman pull oci-archive:file.tar instead of the desired unconfined_u:object_r:container_ro_file_t:s0. On RHEL (but not fedora) this leads to unusable containers since programs inside the container will get permission denied (EACCSS) errors when reading files with the "wrong" labels, hinting at a possible other bug in the overlayfs kernel driver? Either way, it does not make much sense for a container to have labels since the target system wants to label the files inside the container so we should not (and on RHEL indeed must not) label the files inside the container.
