Description Dave Anderson 2016-11-09 18:58:53 UTC
Description of problem:

The RHEL7.4 errata version of the crash utility should be
rebased to the current upstream version, currently at version
crash-7.1.6, and soon to be released crash-7.1.7.  There are 
over 60 new features and other bug fixes that have been applied to
the upstream version make the tool significantly more useful
than the current RHEL7.3 version, which is based upon crash-7.1.5.
This includes new options such as "live" QEMU ramdump dumpfiles,
KASLR support for x86_64 and ARM64, a new "bt -v" command to check
all tasks for stack overflows, an enhancement to determine structure
member data if the member is contained within an anonymous structure
or union, a more efficient "list -s" command for dumping members of
lists with thousands of members, support for the radix MMU in
Power ISA 3.0 machines, and PPC64/BOOK3E virtual memory management,
support for the new CONFIG_THREAD_INFO_IN_TASK kernel configuration,
and many bugfixes, including for the ARM64 "bt" command, the "tree -t"
radix-tree dumper, the "dis" and "mach" command for KASLR kernels,

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,
Fedora, and soon, pegas kernel crash dumps.

The simple rebase description is fine.  I went ahead and changed it to
crash version 7.1.9.
