[Crash-utility] [ANNOUNCE] crash version 6.0.0 is available
Download from: http://people.redhat.com/anderson
Changelog:
- Updated the embedded gdb version to FSF gdb-7.3.1. This change is
required for kernels built with gcc-4.6.1, which now defaults to
using -gdwarf-4. When using prior versions of crash on such a
vmlinux file, it fails immediately with the message "Dwarf Error:
wrong version in compilation unit header (is 4, should be 2) [in
module vmlinux]" followed by "crash: vmlinux: no debugging data
available".

- Incremental patch for the SADUMP dumpfile support that was introduced
in crash-5.1.8. The patchset fixes minor bugs, cleans up the sadump
module, addresses the issue of gathering the first 640KB backup from
a kdump-enabled kernel, prepares for makedumpfile's support of the
SADUMP format, and has "bt" display the stored register set when the
compressed kdump was generated from an SADUMP dumpfile.

- Fix for the "gdb" command, or any command that resolves to a gdb
command, to allow redirection to a pipe or file. This addresses a
regression that was introduced by an unrelated "gdb" command fix
in crash-5.1.4 that prevented the stripping of quotation marks from
the input line. Without the patch, redirection of a "gdb" command
to a pipe or file fails with the error message "gdb: gdb request
failed: <original-command-line-including-redirection>".

- Fix for live system analysis of 32-bit PPC kernels. Without the
patch, the session would fail after displaying the error message:
WARNING: machine type mismatch:
crash utility: PPC
vmlinux: (unknown)
(nakayama.ts(a)ncos.nec.co.jp)
- Fix to allow vmalloc memory access on 32-bit PPC kernels. Without
the patch, the warning message "WARNING: cannot access vmalloc'd
module memory" would be displayed during invocation, and kernel
virtual memory that was vmalloc'd could not be accessed.

- Fix to correctly gather task addresses from 32-bit PPC kernels.
Without the patch, during invocation a stream of error messages
indicating "crash: invalid task address in pid_hash: <address>"
would be displayed.

- Fix for the "bt" command in 32-bit PPC kernels. Without the patch,
the "bt" command would generate a segmentation violation.
