1693092 – [abrt] [faf] adcli: raise(): /usr/sbin/adcli killed by 6

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 Lukas Slebodnik 2019-03-27 07:22:30 UTC

This bug has been created based on an anonymous crash report requested by the package maintainer.

Report URL: http://faf.lab.eng.brq.redhat.com/faf/reports/bthash/b16b5db011da669ac06173eb89c9d4c5c85b4893/

Comment 4 Sumit Bose 2019-03-27 07:53:33 UTC

Hi Lukas,

thanks for the report, this is most probably a double-free in adcli. Do you, by chance, have the verbose output of adcli, so that I can see how it got into this state?

bye,
Sumit

I tried to run adcli with valgrind; but I could not see any error or failure.

We were not able to reproduce this crash so far. Any help with identifying the scenario is welcome!

Comment 11 Sumit Bose 2019-04-12 15:41:00 UTC

Hi,

jfyi, I came across the issue by chance and think I know how to fix it. It was introduced by the patch for https://bugzilla.redhat.com/show_bug.cgi?id=1630187. If you agree I will close this ticket as duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1630187 and switch https://bugzilla.redhat.com/show_bug.cgi?id=1630187 from ON_QA to POST?

bye,
Sumit
