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.
Previously, during the shut down sequence of the escd daemon, the daemon reported a failure of certain instances. ESC terminated unexpectedly with a segmentation fault as a consequence. This update modifies the daemon to exit quietly. As a result, ESC no longer terminates unexpectedly.

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.
Looks like this is happening on cleanup, when the process is on the way out.
Happening during CoolKey shutting down. Thanks for the report. It would help if there is some reasonable way to reproduce this.
The reason why this is occurring is that the pcsc client call "SCardCancel" is hanging when shutting down CoolKey. ESC put in some simple code to exit when it detects this hanging condition. The problem with the seg fault is addressed in ESC , but it would be better if the issue in pcsc-lite could be addressed so this hang does not occur. We have another bug filed for this issue. The reason why this is important is because when Firefox has the Coolkey pkcs#11 module loaded, it is subject to this very hanging condition.

Previously, during the shut down sequence of the escd daemon, the daemon reported a failure of certain instances. ESC terminated unexpectedly with a segmentation fault as a consequence. This update modifies the daemon to exit quietly. As a result, ESC no longer terminates unexpectedly.
Executed following tests on a RHEL-6.2 i386 and x86_64 desktop with esc-1.1.0-23.el6 installed, escd does not crash.
1. Make sure "escd" is running (ps -fe | grep escd), if not launch it.
2. Use the "kill" program to send a signal to shutdown. "kill <pid-of-escd>"
3. Place a tail on the system log "tail -f /var/log/messages".
4. Upon repeated trials of this scenario, escd does not register a crash.
Marking the bug verified.
