731977 – memory leak: 25,830 bytes in 315 blocks are definitely lost

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 Petr Sklenar 2011-08-19 10:33:19 UTC

Description of problem:
memory leak: 25,830 bytes in 315 blocks are definitely lost

Version-Release number of selected component (if applicable):
ipmitool-1.8.11-11.el6.i686

How reproducible:
deterministic

Steps to Reproduce:
1. valgrind --leak-check=full --log-file=valgrind.log ipmitool -I lanplus -H <> -U USERID -P PASSW0RD sol activate
2.# generate some traffic on the serial console on the PowerEdge machine (e.g. cat /var/log/messages; dmesg; while true; do yes; done; ...)
# kill (gently, with sigint or sigterm) the ipmitool
3. check valgrind.log
  
Actual results:
==14834== LEAK SUMMARY:
==14834==    definitely lost: 27,852 bytes in 339 blocks
==14834==    indirectly lost: 0 bytes in 0 blocks
==14834==      possibly lost: 0 bytes in 0 blocks
==14834==    still reachable: 452 bytes in 8 blocks
==14834==         suppressed: 0 bytes in 0 blocks
==14834== Reachable blocks (those to which a pointer was found) are not shown.
==14834== To see them, rerun with: --leak-check=full --show-reachable=yes
==14834== 
==14834== For counts of detected and suppressed errors, rerun with: -v
==14834== Use --track-origins=yes to see where uninitialised values come from
==14834== ERROR SUMMARY: 1166606 errors from 124 contexts (suppressed: 37 from 10)


Expected results:
no memory leak
