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 Dave Anderson 2012-07-13 14:59:07 UTC 
Description of problem:

The RHEL6.4 errata version of crash should be rebased to the most recent
upstream version of the crash utility.

It is far more efficient, and far safer, to rebase to the upstream 
version than to attempt to selectively backport the patches required for
the current set of bugzillas requested for RHEL6.4.  More importantly,
the new features and other fixes that have been applied to the upstream 
version make the tool significantly more useful than the current RHEL6 
version.

It should also be noted that Fedora 18, and therefore RHEL7, kernels
are incompatible with the current RHEL6 version of the crash utility.
This is due to fundamental changes in the recent upstream kernel, such
as the 3.5 change to the printk log buffer format, which causes the 
crash session to fail during initialization, the 3.3 rework of the VFS
subsystem which cause several key commands to fail, and a number of other 
smaller changes that affect command behavior with the later kernels. 

As the owner and upstream maintainer, one of my primary goals is, and
always has been, to maintain backwards-compatibility whenever new fixes
or features are applied.  Therefore the risk of regression is less with a
rebase than it would be with selective backports because the RHEL6.4
bugzilla-requested fixes are based upon the state of the upstream version. 

It should be noted that nothing goes into the upstream version without
my approval, and my testing.  I perform all my testing on RHEL6 systems,
and test changes against a sample set of RHEL3, RHEL4, RHEL5, RHEL6, 
upstream and Fedora kernel crash dumps.
