Download from: http://people.redhat.com/anderson Changelog: - Fixed several typos in the updated crash.8 man page. (bob.montgomery@xxxxxx) - Created a new "rd -a" option that displays printable ASCII data only, starting from the specified location. If a "count" argument is not entered, the display stops upon encountering the first non-printable character. (anderson@xxxxxxxxxx) - Fix for the "search -k" option on X86 kernels whose first memmap page structure does not map to physical address 0. Without the patch, the identity-mapped region of the first memory node would not be searched. (anderson@xxxxxxxxxx) - Fix for the "search -k" option in the highly unlikely case of kernels that have multiple NUMA nodes that are not sequential with respect to their node IDs and the physical memory they reference, have physical memory holes between any of the nodes, and do not have memmap page structures referencing the non-existent inter-node physical memory. In that event, it is conceivable that a NUMA node would be skipped. (anderson@xxxxxxxxxx) - If the "kmem <address>" argument is a virtual address inside a kernel module, the first item displayed is the address, followed by its symbol type, and its symbol-name-plus-offset string. This patch appends the module name in brackets, similar to what is displayed if "sym <address>" is entered. (anderson@xxxxxxxxxx) - Fix for "kmem -s <address>" in kernels configured with CONFIG_SLUB and CONFIG_PAGEFLAGS_EXTENDED if the address is contained in a page other than the first page in a compound, multi-page, slab. Without the patch, the command would fail with the message "kmem: address is not allocated in slab subsystem: <address>". (anderson@xxxxxxxxxx) - Created a new "rd -N" option that displays 16- and 32-bit data in network byte order, performing byte-swapping if appropriate. (makc@xxxxxxxxx) - Fix for a compiler warning when building with "make warn". Without the patch, memory.c generates a message indicating "kernel.c: In function ÃâËback_traceÃââ:" followed by 17 messages indicating "kernel.c: 2187: warning: ÃâËbtsave.<member>Ãââ may be used uninitialized in this function", where there is one message for each <member> of the bt_info structure. (anderson@xxxxxxxxxx) - Updated the #define of NR_SECTION_ROOTS to match its change upstream that prevents its value from being calculated to be zero. (takuo.koguchi.sw@xxxxxxxxxxx, anderson@xxxxxxxxxx) - Fix for a double-free() in the unlikely event of a readmem() failure in the ARM architecture's read_module_unwind_table() function. (mika.westerberg@xxxxxx) - Updates to support CONFIG_SPARSEMEM for the ARM architecture. (mika.westerberg@xxxxxx) - Extended the "mach" command to display the size and address of each per-cpu IRQ stack and per-cpu exception stack, if they exist. This extension is applicable to the x86_64 and ppc64 architectures, and the x86 architecture if applicable. Prior to this patch, the values were only accessible via "help -t" or "help -m". (anderson@xxxxxxxxxx) - Created a new "kmem -o" option that dumps each cpu's offset value that is added to per-cpu symbol values to translate them into kernel virtual addresses. Prior to this patch, the values were only accessible via "help -k". (anderson@xxxxxxxxxx) - Removed the "kmem [-[l|L][a|i]]" options from being advertised by the "kmem" help page; the options have been obsolete since the Linux version 2.2 timeframe. (anderson@xxxxxxxxxx) - Fix to support Linux 3.x version number change. Without the patch, the crash session fails with kernel version 3.0 and later, displaying the message "WARNING: kernel version inconsistency between vmlinux and [live memory or dumpfile]", followed by the fatal error message "crash: incompatible arguments: vmlinux is not SMP -- [live system or dumpfile] is SMP". (sebott@xxxxxxxxxxxxxxxxxx, anderson@xxxxxxxxxx) - Updates to the sial.c extension module to support the Linux 3.x version number change. (sebott@xxxxxxxxxxxxxxxxxx, Luc.Chouinard@xxxxxxxxxxxxxxxx) - Created a new "kmem -g [flags]" option that displays the enumerator value of bits in the page structure's "flags" field. With no "flags" argument, the enumerator value of all bits are displayed; when a hexadecimal "flags" option is added, just the bits in the value are translated. This option only works with 2.6.26 and later kernels, which contain the "enum pageflags".
