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 Denis Volkov 2020-01-08 13:33:56 UTC 
Description of problem:
After enabling pipeline mode in ansible on the user with tlog session recording enabled, simple playbooks fail

Version-Release number of selected component (if applicable):
tlog: tlog-6-1.el8.x86_64
ansible: 2.9.1 (not RHEL)

Steps to Reproduce:
1. Enable session recording:
chsh root -s /usr/bin/tlog-rec-session

2. Start test playbook with pipeline enabled

    $ ansible-playbook plays/ping-pipe.yml -i inv/hosts
PLAY [all] ********************************************************************************************************************************************************************************************************

TASK [ping all hosts] *********************************************************************************************************************************************************************************************
fatal: [rhel8]: FAILED! => {
    "changed": false,
    "rc": 0
}

MSG:

MODULE FAILURE
See stdout/stderr for the exact error


PLAY RECAP ********************************************************************************************************************************************************************************************************
rhel8                      : ok=0    changed=0    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0   


Expected results:
Playbook is run without error

Hi  

Customer is requesting information. 

What release is this plan to, do we have any update on target date (some idea when)?


Thanks

Hello,

This is not fixed upstream yet but I am planning to work on it after finishing some other development tasks, I expect the fix will be available in the RHEL 8.3 release. I will update on the progress of this BZ when I have some new details to share. Thank you for your patience.
