- Fix for support of paravirtual x86 xendumps that were:
1) created on host machines with greater than 4GB of
memory, and
2) the active guest task at crash-time had been assigned
a page
directory page (cr3) with a machine
address greater than 4GB.
If both of the above apply, the crash session would fail
with one of
two error messages, either "crash: cannot read/find cr3
page", or
"crash: cannot create xen pfn-to-mfn mapping". (anderson@xxxxxxxxxx)
- Fix for the "kmem -p [page-struct-address]" command construct,
which
would cause a segmentation violation when run on SPARSEMEM
kernels.
(anderson@xxxxxxxxxx)
- Added a new "struct -u" option, which indicates that the subsequent
address argument is a user virtual address in the current
context.
This option could be used, for example, if a known kernel
data
structure exists at user virtual address in the current
context,
or if the debuginfo data of a user program were loaded into
the
crash session via the gdb "add-symbol-file" command.
(anderson@xxxxxxxxxx)
- Added new "rd -f" and "struct -f" options, which indicate that
the
subsequent address argument is a dumpfile file offset.
These options
could be used, for example, to print a known kernel data
structure
that exists in the dumpfile header, or to simply dump data
directly
from the dumpfile. (anderson@xxxxxxxxxx)
- Cosmetic fix to prevent double-printing of "kmem -p" and "kmem
-v"
headers when they are passed multiple address arguments.
