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.

Notably, this rebase adds new options such as `dis -s`, `dis -f`, `sys -i`, `list -l`, new support for Quick Emulator (QEMU) generated Executable and Linkable Format (ELF) vmcores on the 64-bit ARM architectures, and several updates required for support of recent upstream kernels. It is safer and more efficient to rebase the crash packages than to backport selectively the individual patches.	Story Points:	---

Description Dave Anderson 2015-12-17 19:56:26 UTC

Description of problem:

The RHEL7.3 errata version of the crash utility should be
rebased to the current upstream version, currently at version
crash-7.1.4.  There are over 50 new features and other fixes 
that have been applied to the upstream version make the tool 
significantly more useful than the current RHEL7.2 version, 
which is based upon crash-7.1.2.  This includes new options such
as "dis -s", "dis -f", "sys -i", "list -l", new support for QEMU
generated ARM64 ELF vmcores, and several updates required for 
support of recent upstream kernels, which is now relevant given
that the RHEL7 ARM64 kernel has been rebased to upstream Linux 
version 4.4.  

It is far more efficient, and far safer, to rebase the crash 
package than to attempt to selectively backport individual patches.
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.  The risk of regression is 
less with a rebase than it would be with selective backports.

It should be noted that nothing goes into the upstream version 
without my approval.  I perform all my testing on Fedora and RHEL
kernel versions, where each individual change is meticulously 
tested against a sample set of RHEL3, RHEL4, RHEL5, RHEL6, RHEL7,
and Fedora crash dumps.
