- Fix for the "kmem -p" command in kernels configured with CONFIG_SPARSEMEM, i.e., not CONFIG_SPARSEMEM_EXTREME. Without the patch, the page structure address for each physical page was erroneous. (oomichi(a)mxs.nes.nec.co.jp) - Fix for the "kmem -p" command output of MAPPING and INDEX values on kernels where the mapping and index members of the page structure are contained within anonymous unions. Without the patch, those fields may be dashed-out. (bob.montgomery(a)hp.com, anderson(a)redhat.com) - Fix for the "mod" command to search for module object files in the /lib/modules/<release>/updates directory tree before looking in /lib/modules/<release>. (charlotte.richardson(a)stratus.com) - Fix for the "waitq" command for 2.6.15-era and later kernels, which replaced the __wait_queue.task member with the __wait_queue.private member. Without the patch, the command would fail with the error message: "waitq: invalid structure member offset: __wait_queue_task". (atyson(a)hp.com) - SIAL interpreter fix for an "operation on 'v1' may be undefined" warning in sial_exeop(). (bwalle(a)suse.de) - Fix for several unpredictable failure modes when attempting "crash -h [command] > outputfile" from a shell command line. (anderson(a)redhat.com) - Addressed compiler warnings generated by extensions/echo.c and extensions/dminfo.c. (bwalle(a)suse.de, anderson(a)redhat.com) - Addressed compiler warnings generated by lkcd_common.c, lkcd_v8.c and symbols.c when using: -O2 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -fno-builtin-memset -fno-strict-aliasing (bwalle(a)suse.de) - Fix for "kmem -p" on i386 CONFIG_SPARSEMEM kernels with greater than 4GB of memory. Without the patch, the physical address value wraps back to zero after physical page ffff0000. (oomichi(a)mxs.nes.nec.co.jp) - Fix to redirect SIAL script command output to pipes, files, etc., in the same manner as native crash commands. (Robert.Denman(a)teradata.com, anderson(a)redhat.com) - Fix for ppc64 kernels with 64K pages whose PTE_RPN_SHIFT has changed from 32 to 30. Without the patch, an initialization-time warning message "WARNING: cannot access vmalloc'd module memory" would occur, the "mod" command would fail with the same message, and "kmem -s" failures could occur when attempting to read a kmem slab cache name string. Translations and reads of vmalloc'd kernel virtual addresses and user virtual addresses would appear to work, but bogus data was returned because the resultant physical address that was read was incorrect. (anderson(a)redhat.com) - Fix for "kmem -s" if a slab cache whose name string cannot be read is encountered. Without the patch, a fatal error message would be displayed and the command aborted. With this patch, a non-fatal warning message is displayed, and the cache name is indicated as "(unknown)". (anderson(a)redhat.com) - Fix for x86-64 SPARSEMEM kernels with CONFIG_NUMA off. Without the patch, the crash session fails during initialization with the message "crash: invalid structure member offset: pglist_data_node_mem_map". (sachinp(a)in.ibm.com) - Fix to use the ia64 physical start address from the LKCD dump header instead of the default value. This was reported as bug on an SGI machine. (bwalle(a)suse.de) - For s390[x] kernels the page table allocation method will be changed such that instead of 3 levels, it will be now possible to allocate 4 levels. The current implementation of the page table walk functions in the crash utility makes assumptions on how the page tables are allocated by the kernel, e.g. 3 levels are hard coded. This patch changes that, and the page table walk is done only according to the s390 architecture without assumptions on the implementation in the kernel. (holszheu(a)linux.venet.ibm.com) - Fix for LKCD dumpfile access failures that abort() the crash session after displaying an error message indicating a problem with physical memory zones in the dumpfile. Without the patch, the crash session would end immediately after displaying an error message of the sort: "conflicting page: zone 0, page 0: 0, 177160130 != 65536". That error message will now only be displayed if the crash debug mode is 1 or more, a readmem() "seek error" will be displayed instead, and the session will return to the "crash>" prompt.
