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 of problem:
The NFS kerberos regression testcase of Bug 1419280 starts to fail since sssd-2.7.3-1.el9.
The test scenario is just
1) set up nfs mount with sec=krb5 (any flavor)
2) access a file or directory on the mount with multiple uids simultaneously
And we can use the scripts provided by Frank Sorenson:
https://bugzilla.redhat.com/show_bug.cgi?id=1419280#c1https://bugzilla.redhat.com/show_bug.cgi?id=1419280#c2
Version-Release number of selected component (if applicable):
since sssd-2.7.3-1.el9 (maybe the nfs/idmap related packages from http://download.eng.bos.redhat.com/brewroot/packages/sssd/2.7.3/1.el9/x86_64/)
start fail sssd-2.7.3-1.el9 - https://beaker.engineering.redhat.com/jobs/6893573
latest pass sssd-2.7.1-2.el9 - https://beaker.engineering.redhat.com/jobs/6894865
How reproducible:
reliable
Actual results:
process get hang:

Expected results:
process exist cleanly
Additional info:
This regression also happens in rhel8 sssd-2.7.3-1.el8 but behavior is a bit different.
I'm not sure if this is sssd issue but as the package sssd version matters please help check what update/change is culprit.
