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.

Description Renaud Métrich 2021-09-15 08:35:53 UTC 
Description of problem:

When a process is fired from the kernel (has PID 2 as parent) (e.g. /usr/lib/systemd/systemd-cgroups-agent) and the process crashes, the systemd-coredump instance, which is also fired from the kernel (also has PID 2 as parent) is looping forever in get_mount_namespace_leader().

Please hence backport Upstream commit 0c4d1e6d96a549054bfe0597d197f829838917f1 


Version-Release number of selected component (if applicable):

RHEL8


How reproducible:

Always on customer systems having /usr/lib/systemd/systemd-cgroups-agent
Don't know how to have this process running ...
