7.32. crash
Updated crash packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The crash packages provide a self-contained tool that can be used to investigate live systems, and kernel core dumps created from the netdump, diskdump, kdump, and Xen/KVM "virsh dump" facilities from Red Hat Enterprise Linux.
Note
The crash packages have been upgraded to upstream version 6.1.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#840051)
Bug Fix
- BZ#843093
- A recent time-keeping backport to the Red Hat Enterprise Linux 6 kernel caused the crash utility to fail during initialization with the "crash: cannot resolve: xtime" error message. This update modifies crash to recognize and handle the time-keeping change in the kernel so that crash now successfully starts up as expected.
Enhancements
- BZ#739094
- The crash utility has been modified to support dump files in the firmware-assisted dump (fadump) format for the 64-bit PowerPC architecture.
- BZ#834260
- The "struct -o" option has been enhanced to accept a virtual address argument. If an address argument is entered, the structure members are prepended by their virtual address.
- BZ#834276
- The "bt" command has been enhanced by adding new "-s" and "[-xd]" options that allow displaying symbol names plus their offset in each frame. The default behavior is unchanged where only the symbol name is displayed. The symbol offset is expressed in the default output format, which can be overridden using the "-x" (hexadecimal) or "-d" (decimal) options.
All users of crash are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
