Description:
crash - kernel debugging utility, allowing gdb like syntax
Changes:
crash (5.1.1-1) unstable; urgency=low
.
* New upstream version 5.1.1 (see
http://people.redhat.com/anderson/crash.changelog)
* Fix for the potential to miss tasks when walking the pid_hash table in
2.6.24 and later kernels.
* Enhancement for the ARM architecture's "bt" command to print out the user
space register set for tasks entering the kernel via the syscall entry
point.
* Rework of the handling of "set" commands that are put in .crashrc files so
that only the following options are resolved prior to session
initialization: silent, console, core, edit, namelist, and zero_excluded.
All others are resolved immediately after session initialization is
complete. Accordingly, the use of "set -c <cpu>", "set -p", "set -a
[task|pid]" and set [pid|task]" are now acceptable .crashrc commands.
* The entering of "set -v" in a .crashrc file would cause an immediate
segmentation violation. The "set" command rework above defers the command
until session initialization is complete.
* The entering of "set dumpfile <filename>" in a .crashrc file would cause a
fatal "seek" error during session initalization with most most dumpfile
types, so the "dumpfile" option has been removed from the "set" command.
* The execution of "alias" commands from a .crashrc file used to be
performed immediately; that behavior has been changed so that they are
executed immediately after session initialization is complete.
* Enhancement of the "repeat" command to allow command aliases.
* Fix for running "kmem -s" on a live system if an offline cpu is brought
back online while the command is executing. Without the patch, the online
operation may cause a segmentation violation.
* Change the behavior of "bt -[tT]" to allow the command options to be run
on active tasks on live systems. Without the patch, both command options
would display the task data banner followed by "(active)".
* Fix for the ARM architecuture's "irq" command when run on 2.6.36 and later
kernels. Without the patch, the command fails with the error message
"irq: invalid kernel virtual address: 23 type: irq_chip typename". The
fix replaces the custom ARM IRQ dumping function with the
architecture-neutral version.
* Introduced support for using /proc/kcore as an alternative source of live
memory to /dev/mem. Doing so allows vmalloc memory access on 32-bit
architectures when the underlying mapped physical memory is in highmem,
which is not allowed by the /dev/mem driver. It would also be usable on
systems that are configured with CONFIG_STRICT_DEVMEM but still configured
with CONFIG_PROC_KCORE. To enforce the use of /proc/kcore, it may be
entered on the command line.
* If a live crash session attempts to use /dev/mem as a live memory source,
and it is determined that the system is configured with
CONFIG_STRICT_DEVMEM, /proc/kcore will automatically be tried as an
alternative.
* Fix to allow "/dev/crash" to be entered on the command line for live
sessions. Because it is used automatically if it exists, it is never
necessary to enter it on the command line. However, if it is used,
without the patch, the session fails during initializaion with the error
message "crash: /dev/crash: No such file or directory" if the crash.ko
driver is a module (RHEL4/RHEL5), or "crash: /dev/crash: not a supported
file format" if the driver is built into the kernel (RHEL6).
* Fix for the ARM "bt" command to address the issue behind faulty warning
messages that indicate "WARNING: UNWIND: unsupported personality routine".
* Fix for the ARM "bt" command to address the issue behind faulty warning
messages that indicate "bt: WARNING: UNWIND: cannot find index for
<address>".
