Description Dave Anderson 2009-10-09 15:24:37 UTC

Description of problem:

The RHEL5.5 errata version of crash should be rebased to the current 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 approved for RHEL5.5.  Furthermore, the new features and other fixes
that have been applied to the upstream version make the tool significantly more
useful than the current RHEL5 version.

I can confidently state the above primarily because I am the original author,
the upstream maintainer, and the Red Hat maintainer of the crash utility.

As the 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 because the RHEL5.5 bugzilla-required 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 RHEL5 systems, and test
changes against a sample set of RHEL3, RHEL4, RHEL5 and upstream/Fedora kernel
crash dumps.

Furthermore, as a practical manner, the current RHEL5 version of crash needs
several updates to support upstream kernels.  That is an example of the kinds
of changes that are continually folded into the upstream version of crash as
the underlying kernel itself changes.  Given the onset of RHEL6, it only makes
sense that the RHEL5 version of crash can be used with the oncoming RHEL6
kernels.

And lastly, there have been several new debugging features added to the
upstream version that can only serve to aid our support and development
personnel in dealing with customer crashes more efficiently.  Details
