[Crash-utility] crash version 4.0-6.2 is available
- Implemented a new "rd -S" option which, like the "-s" option,
displays the symbolic translation of kernel virtual addresses,
but also recognizes the virtual addresses of slab objects, and when
found, the address is replaced by the kmem_cache slab name string
inside brackets. (anderson(a)redhat.com)
- Make the found address displayed by "kmem -[sS] <address>" be the
address of the containing object if the <address> argument is
offset from the beginning of the object. This only applies to
kernels using kernel/slab.c; CONFIG_SLUB kernels currently do display
the address of the containing object.

- Fix for "kmem -[sS] [address]" in 2.6.25 CONFIG_SLUB kernels, which
address changes in the kernel's per-slab free list tracking. Without
the patch, error messages of the type "kmem: invalid kernel virtual
address: 10700 type: get_freepointer" would be seen when the full
list of objects in a per-cpu slab was displayed.

- Fix for "kmem -[sS] <slab-address>" in 2.6.25 CONFIG_SLUB kernels,
in which the slab structure is actually a page struct. Some slab
addresses would not be recognized as such, and therefore without the
patch, error messages of the type "kmem: address is not allocated in
slab subsystem: <slab-address>" would be seen.

- Fix for an initialization-time failure with Ubuntu kernels because
of a mismatch between the /proc/version string and the linux_banner
string, due to additional information appended to the linux_banner
string in Ubuntu kernels. (anderson(a)redhat.com, asid(a)hp.com)
- Fix for the "net" command in 2.6.22 and 2.6.23 kernels, where the
"dev_base" net_device structure was replaced by the
"dev_base_head"
list_head. Without the patch, the "net" command with no arguments
would fail with the error message: "net: dev_base does not exist!".
(eteo(a)redhat.com)
- Fix for the "net" command in 2.6.24 and later kernels where the
global "dev_base_head" list_head has been removed, and the network
devices are linked from the "init_net" net structure. Without the
patch, the "net" command with no arguments would fail with the
error message: "net: dev_base does not exist!".

- For kernels configured with CONFIG_SLUB, "kmem -S" has been updated
to properly differentiate whether a cache's "full" slabs are tracked
but whose full list is empty, or whether the full slabs are not
tracked at all. Without this patch, a cache's full list could be
indicated as "(empty)" instead of the more correct indication of
"(not tracked)". (i-kitayama(a)ap.jp.nec.com, anderson(a)redhat.com)
- Fix for the "vm" command when the crash session was invoked with
the -s command line option. Without the patch, if invoked prior to
a "set", "ps" or "vtop" command, the "vm"
command run against a
task other than the initial context would mistakenly indicate that
the task contained no virtual memory.

- Fix/workaround for the "search -k" command option on relocatable
2.6-era ia64 machines configured with CONFIG_SPARSEMEM. Without
the patch, an immediate segmentation violation occurs.
