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 Íñigo Huguet 2022-10-18 11:47:21 UTC 
Description of problem:
It's not possible to execute trace-cmd
Installed normally with `dnf install trace-cmd`

Version-Release number of selected component (if applicable):
RHEL-9.2.0-20221006.d.0

How reproducible:
Always

Steps to Reproduce:
Execute trace-cmd

Actual results:
trace-cmd: symbol lookup error: trace-cmd: undefined symbol: tep_filter_free

Expected results:
trace-cmd works

Additional info:
It seems that tep_filter_free is part of libtraceevent. It doesn't have these symbols exported:
readelf -Ws --dyn-syms /usr/lib64/libtraceevent.so.1 | grep tep_filter

In Fedora 34 I can execute trace-cmd, and libtraceevent has these symbols exported:
readelf -Ws --dyn-syms /usr/lib64/libtraceevent.so.1 | grep tep_filter

Comment 1 Ziqian SUN (Zamir) 2022-10-19 01:19:12 UTC 
See bug 2134397.

Before this get fixed, if you want to use trace-cmd in RHEL-9, you can workaround this by temporary downgrade to libtraceevent-1.1.1-8.el9 (the libtraceevent version in 9.1) and wait for a permanent fix.
