------------------------------------------------------------------- Fri Jan 27 18:02:52 CET 2017 - dmair@suse.de - crash was broken by this upstream kernel commit: 8244062 modules: fix longstanding /proc/kallsyms vs module insertion race. When cores from kernels with that are used then launch of crash fails with the message: "crash: invalid structure member offset..." Fix is composed of the following patches: crash-fix_for_changes_to_kernel_module_structure.patch crash-Introduction-of-the-dis-f-address-option-which-disas.patch crash-Fix-for-the-dis-command-on-architectures-with-variab.patch crash-fix_for_dis_at_highest_module_symbol.patch crash-invalid_structure_member_with_current_kernels.patch (bsc#1002876) ------------------------------------------------------------------- Thu Nov 5 20:04:16 CET 2015 - dmair@suse.de - crash-7.0.5.xen-patch: Fix changed xen 4.2.5 domain structure member (bsc#922005) - crash-Fix-for-the-X86_64-bt-and-mach-commands-when-running.patch: Fix mis-labeled per-cpu exception stacks (bsc#940720) ------------------------------------------------------------------- Thu Sep 4 11:59:48 UTC 2014 - ptesarik@suse.cz - crash-kmem_cache-downsize.patch: Fix kmem slab initialization failures (bnc#885082). ------------------------------------------------------------------- Mon Aug 18 11:07:54 UTC 2014 - ptesarik@suse.cz - Module.supported: mark crash.ko supported (bnc#891375). ------------------------------------------------------------------- Thu Jun 12 19:23:17 CEST 2014 - dmair@suse.de - crash-keep-file-orig-with-name-on-select.patch Fix the namelist selection for gdb to have background state used to select file to delete for expansion of compressed file (bnc#877367) ------------------------------------------------------------------- Fri May 16 19:39:11 UTC 2014 - ptesarik@suse.cz - crash_enable_snappy_support.patch: enable snappy support. ------------------------------------------------------------------- Wed Apr 30 07:58:01 UTC 2014 - ptesarik@suse.cz - crash-x86_64-nested-nmi.patch: Fix NMI backtrace for kernels patched to handle nested NMIs (bnc#874179). ------------------------------------------------------------------- Sat Apr 12 20:48:21 UTC 2014 - mmarek@suse.cz - Add # needssslcertforbuild to use the project's certificate when building in a home project. ------------------------------------------------------------------- Tue Feb 18 19:28:45 CET 2014 - dmair@suse.de - Implementation of 7.0.5 from upstream, including patch refresh Changelog: - Fix for the "runq -g" option for kernels that are configured with CONFIG_FAIR_GROUP_SCHED, but not CONFIG_CFS_BANDWIDTH. Without the patch, the command fails with the message "runq: invalid structure member offset: cfs_rq_throttled". (vinayakm.list@gmail.com) - Add support for Xen PVH guest types introduced in Xen 4.4. Without the patch, running against a Xen 4.4 hypervisor binary would fail during session initialization with the error message "crash: invalid structure member offset: domain_is_hvm". In addition, the PVH guest type is being registered internally as an HVM guest type, the debug "help -X ofs" command's display of the domain_domain_flags offset has been fixed to show it in decimal, and the setting of the internal dc->domain_flags has been fixed to contain all flags set, not just the first one found. (dslutz@verizon.com) - Fix for the "kmem -S" command on Linux 3.1 and later kernels that are configured with CONFIG_SLUB. Because the the page structure's inuse and objects fields used by SLUB were changed from discrete u16 types to bit-fields within an unsigned int, the display of per-node partial slab statistics are incorrect. Without the patch, the TOTAL and ALLOCATED values are incorrectly shown as equal values, and therefore the FREE value is always zero. (anderson@redhat.com) - Fix for the "kmem -S" command for kernels that are configured with CONFIG_SLUB. Eash per-cpu slab object dump may show incorrect ALLOCATED and FREE values; and as seen on Linux 3.5 and later kernels, the TOTAL value and the number of individual objects dumped may also be incorrect (too small). (anderson@redhat.com) - When executing the commands from an input file specified by the "-i <file>" command line option, or when accepting input from a file as a set of commands or as a set of command arguments using the "<" redirection character, unconditionally cease the operation if CTRL-c is entered. Without the patch, depending upon the command that was running when the SIGINT was received, the operation may continue uninterruptibly until the file contents are consumed. (anderson@redhat.com) - Enhanced the "bt -F" option such that if "-F" is entered twice, and if the stack frame contents reference a slab cache object, both the slab cache name and the stack contents will be displayed within brackets. (anderson@redhat.com) - Enhanced the "rd -S" option such that if "-S" is entered twice, and if the memory contents reference a slab cache object, both the slab cache name and the memory contents will be displayed within brackets. (anderson@redhat.com) - Fix for the X86_64 "bt" command to prevent an unwarranted message indicating "WARNING: possibly bogus exception frame" generated from a blocked kernel thread that was in the process of exec'ing a user process via the call_usermodehelper() facility. (anderson@redhat.com) - Fix for the X86_64 "bt" command to more correctly determine the function frame that called into an interrupted function. Without the patch, the first frame just above an IRQ exception frame register dump may show an invalid/stale function. (anderson@redhat.com) - Fix for the X86_64 "bt" command if a page fault exception was generated by the invalid contents of the RIP register. Without the patch, the exception frame register dump is not displayed above the "page_fault" stack frame; and in a related issue, the "bt -e" option will not find and display the exception frame. (anderson@redhat.com) - When invoking a crash session with a compressed vmlinux file, make the same host-machine/vmlinux endian verification that is done with uncompressed vmlinx files. (anderson@redhat.com) - Reduce the number of CTRL-c entries required to unconditionally terminate any manually-entered command from three to one. (anderson@redhat.com) - Fix for the X86_64 "bt" command if an async page fault exception occurred in a KVM guest running a Linux 2.6.38 or later kernel. Without the patch, the exception frame register dump is not displayed above the "async_page_fault" stack frame. (anderson@redhat.com) ------------------------------------------------------------------- Wed Jan 29 13:19:18 CET 2014 - ro@suse.de - disable build_kmp on i586 and s390, SLE-12 does not build a runnable kernel there ------------------------------------------------------------------- Fri Jan 24 14:23:12 UTC 2014 - ptesarik@suse.cz - Enable ppc64le: o crash-patch-gdb.patch: allow applying custom gdb patches o crash-gdb-7.6.series: series file for gdb patches o gdb-7.6-ppc64_sysv_abi_push_float.patch: backported dependency o gdb-7.6-bound_minimal_symbol.patch: dtto o gdb-7.6-add-powerpc64le-linux.patch: dtto o gdb-7.6-update-autoconf-2013-04-24.patch: dtto o gdb-7.6-ppc_insns_match_pattern.patch: dtto o gdb-7.6-floatformat.patch: dtto o gdb-7.6-ppc64-ELFv2-trampoline-match.patch: dtto o gdb-7.6-update-autoconf-2013-06-10.patch: dtto o gdb-7.6-ppc64le.patch: patch used for the gdb package ------------------------------------------------------------------- Fri Jan 24 00:21:49 UTC 2014 - dmair@suse.com - Implementation of 7.0.4 from upstream and patch refresh. - Fix for the "ps" command's display of per-task RSS and %MEM values in Linux 2.6.34 and later kernels in which SPLIT_RSS_COUNTING is enabled. Without the patch, the values are only taken from each task's mm_struct.rss_stat structure, which may contain stale values because they may not be synchronized with the RSS values stored in each per-thread task_struct.rss_stat structure; this may lead to invalid or slightly low RSS values, and worst-case, the %MEM value may show garbage percentage values. (vinayakm.list@gmail.com) - Addressed a few (harmless) Coverity Scan complaints in diskdump.c: 1579:dead_error_line – Execution cannot reach this expression ""|"" inside statement "fprintf(fp, "%sDUMP_DH_COMP...". 1574:dead_error_line – Execution cannot reach this expression ""|"" inside statement "fprintf(fp, "%sDUMP_HEADER_...". 1571:dead_error_line – Execution cannot reach this expression ""|"" inside statement "fprintf(fp, "%sDUMP_HEADER_...". (anderson@redhat.com) - Addressed two warnings when compiling diskdump.c on 32-bit architectures when the snappy library is built in: diskdump.c:1046: warning: passing argument 3 of 'snappy_uncompressed_length' from incompatible pointer type /usr/include/snappy-c.h:120: note: expected ‘size_t *’ but argument is of type ‘ulong *’ diskdump.c:1056: warning: passing argument 4 of ‘snappy_uncompress’ from incompatible pointer type /usr/include/snappy-c.h:103: note: expected ‘size_t *’ but argument is of type ‘ulong *’ (anderson@redhat.com) - Created a simpler interface with the internal do_list() function. Currently, if a caller wants to gather the contents of a list into an array, it must do the following: (1) call hq_open() so that the list contents will be verified and saved in the hash queue (2) call do_list() to store the list in the hash queue and return the number of entries in the list (3) allocate a buffer to store the array of entries in the list (4) pass the allocated buffer to retrieve_list() to be populated from the hash queue (5) call hq_close() With this patch, if the passed-in list_data.flags field has a new LIST_ALLOCATE bit set, then do_list() will perform steps (1), (3), (4) and (5) above. The caller can access the allocated array via a new list_data.list_ptr member, and, when done parsing the list, the allocated buffer should be returned via FREEBUF(). The only restriction is that the hash queue cannot be currently in use, or the do_list() call will fail. It should also be noted that there are circumstances where it still makes sense that steps (1), (3), (4) and (5) are performed by the do_list() caller. (anderson@redhat.com) - Modified the internal parent_list() function, used by "ps -p", to utilize the simpler new do_list() functionality described above. (anderson@redhat.com) - Modified the internal dump_vmap_area() function, used by the "kmem -v", "kmem <address>" and "search" commands, to utilize the simpler new do_list() functionality. (anderson@redhat.com) - Modified the internal nr_blockdev_pages() function, used by the "kmem -i", to utilize the simpler new do_list() functionality. (anderson@redhat.com) - Modified the internal get_mount_list() function, used by the "mount" and "files -d" commands, to utilize the simpler new do_list() functionality. (anderson@redhat.com) - Modified the internal get_kmem_cache_list() function, used by the "kmem -[sS]", "kmem <address>", "rd -S" and "bf -F" commands, to utilize the simpler new do_list() functionality. (anderson@redhat.com) - Modified the internal show_net_devices_v2() and show_net_devices_v3() functions, used by the "net" command, to utilize the simpler new do_list() functionality. (anderson@redhat.com) - The "help -r" option has been extended to dump the X86 and X86_64 registers stored in the NT_PRSTATUS notes in netdump ELF, kdump ELF, and compressed kdump dumpfiles. Without the patch, the option only supports ELF dumpfiles created by the "virsh dump --memory-only" facility. (anderson@redhat.com) - Modified the "runq -g" display to show the CFS task_group and cfs_rq addresses; also the current task is also displayed in its CFS or RT queue with with the notation "[CURRENT]" appended to the task data. (Anthony.Chen@Teradata.com) - Additional modification to the "runq -g" to display the task_group and rt_rq addresses for the RT queues, similar in nature to the CFS queue changes are done by the patch above. In addition, the CFS rb_root and RT prio_array addresses are no longer shown given that they can be determined by looking at the cfs_rq and rt_rq structures whose addresses are now displayed. (anderson@redhat.com) - Modified the behavior of the "mod -t" option when running against Linux 2.6.18 and earlier kernels such that the hexadecimal value of the module->license_gplok member is always displayed. Without the patch, if a module's license_gplok boolean or bitmask value is 0, it would only be displayed if the module was unsigned. (anderson@redhat.com, atomlin@redhat.com) - Modified the internal dump_tasks_in_task_group_rt_rq() and dump_RT_prio_array() functions, used by the "runq" command, to utilize the simpler new do_list() functionality. (anderson@redhat.com) - Resurrection of the remote analysis capability for use with the "xen-crashd" daemon running on a Xen Dom0 host, which communicates with a paused or shutdown DomU guest kernel. The daemon can be accessed like so: $ crash localhost:5001,/dev/xenmem vmlinux (dslutz@verizon.com) - Prevent the X86_64 "bt" command from using starting RSP and RIP values taken from the NT_PRSTATUS notes of kdump dumpfiles if the RSP address is not in the task's kernel stack, or in any of the relevant per-cpu exception stacks. This can happen when the number of NT_PRSTATUS notes does not match the number of online cpus. Without the patch, the command may generate a segmentation violation, fail with the error message "bt: cannot determine starting stack pointer", or fail with an error message indicating that the command "cannot transition" from an exception stack to the previous stack. (anderson@redhat.com) - Fix for the X86_64 "bt" command for displaying the backtraces of active tasks running on the non-crashing cpus in kdump dumpfiles in which the "crash_nmi_callback" function frame does not appear in the per-cpu NMI exception stacks. That function frame is normally used as the starting point for the backtraces of those tasks, but if it does not exist, the "notify_die" frame will be used instead. Without the patch, the backtraces of the active non-crashing tasks are incorrect or incomplete. (anderson@redhat.com) - Increment the X86_64 NR_CPUS maximum value from 5120 to 8192 to be able to account for Linux 3.13-rc1 and later kernels in which CONFIG_MAXSMP has been configured. If that is true, the CONFIG_NR_CPUS value is overridden, and the kernel NR_CPUS value will be set to 8192. This will cause the crash session to fail with the messages "WARNING: kernel-configured NR_CPUS (8192) greater than compiled-in NR_CPUS (5120)" and "crash: recompile crash with larger NR_CPUS". (anderson@redhat.com) - A crash-7.0.3 fix for the proper determination of the kernel NR_CPUS configurable for Linux 3.8 and later kernels introduced a regression in Linux 3.8 and later kernels if: (1) the kernel is configured with CONFIG_SLAB, and (2) the sum of the kernel's NR_CPUS and MAX_NUMNODES values exceed the NR_CPUS value compiled into the crash utility. Without the patch, the crash session generates a segmentation fault while it indicates "please wait: gathering kmem slab cache data". (anderson@redhat.com) - Update for the extensions/trace.c extension module to support the ftrace data structure changes introduced in Linux 3.10 kernels. Without the patch, loading the module with the "extend" command fails with the error message "extend: trace.so: no commands registered: shared object unloaded". (d.hatayama@jp.fujitsu.com) - Increment the S390 and S390X NR_CPUS maximum value from 64 to 512. (holzheu@linux.vnet.ibm.com) - Implemented support for the redesigned per-slab object bookkeeping that was introduced in Linux 3.13-rc1 for kernels configured with CONFIG_SLAB. In those kernels, the head page structure associated with each slab is overloaded to serve as the (now removed) slab data structure, and the array of kmem_bufctl_t data structures that used to be appended to each slab data structure for object management has been replaced by a new freelist stack mechanism. Without the patch, the crash session would fail during initialization with the error message "crash: invalid structure member offset: kmem_cache_s_c_num". It should be noted that this patch has only been tested on 3.13-rc1 kernels, which do not have the modified freelist_idx_t in place as of yet, so the replacement of integer-sized indexes with byte or short sized indexes had not been checked in. Furthermore, if this proposed patch set gets accepted: [RFC][PATCH 0/3] re-shrink 'struct page' when SLUB is on. https://lkml.org/lkml/2013/12/11/589 then both CONFIG_SLAB and CONFIG_SLUB support in the crash utility will be broken yet again. (anderson@redhat.com) - In order to facilitate the building of the crash binary with either or both of the optional LZO or SNAPPY compression libraries, two new Makefile targets have been added: $ make lzo $ make snappy Without the patch, the CFLAGS.extra and LDFLAGS.extra files must be created or modified as described in these changelog entries: http://people.redhat.com/anderson/crash.changelog.html#LZO http://people.redhat.com/anderson/crash.changelog.html#SNAPPY This patch simply does the work automatically. After having done it one time, there is no need to use the targets for subsequent builds. The relevant libraries must pre-exist on the build machine. (anderson@redhat.com) - Long overdue update of the README file. (anderson@redhat.com) ------------------------------------------------------------------- Tue Dec 10 18:51:50 UTC 2013 - dvaleev@suse.com - enable ppc64le ------------------------------------------------------------------- Fri Dec 6 11:27:53 UTC 2013 - ptesarik@suse.cz - crash-compressed-booted-kernel.patch: Fix a bug that may cause removal of the booted kernel's vmlinux image (bnc#828260). ------------------------------------------------------------------- Thu Nov 21 19:47:54 UTC 2013 - dmair@suse.com - Implementation of 7.0.3 from upstream and patch refresh. - Fix for the ARM architecture if the backtrace unwind information cannot be gathered during session initialization. Without the patch, the two unwind-related warning messages indicating "WARNING: UNWIND: failed to gather unwind_table list" and "WARNING: UNWIND: failed to initialize module unwind tables" are followed by the fatal error message "crash: cannot hash task_struct entries". (anderson@redhat.com) - Fix for the "help -[Dn]" dumpfile information display of the GUID EFI table in the header of SADUMP dumpfiles. Without the patch, only 33 of the 36 bytes in the table are translated. (d.hatayama@jp.fujitsu.com) - Fix for the determination of the kernel NR_CPUS configurable for Linux 3.8 and later kernels that are configured with CONFIG_SLAB. Without the patch, the kernel's compiled-in NR_CPUS value was incorrectly calculated to be the sum of the kernel's NR_CPUS and MAX_NUMNODES configurables. (anderson@redhat.com) - In the next release of makedumpfile, the status field of the dumpfile header of compressed kdumps will show the compression type that was utilized. The "help -[Dn]" output has been updated to display that information. (anderson@redhat.com) - For kernels configured with CONFIG_SLAB in which an array_cache pointer referenced by a kmem_cache structure is invalid, the individual cache(s) will be marked as invalid. During session initialization, the message "crash: kmem_cache: <cache-address>: invalid array_cache pointer" will be displayed, and during runtime, attempts to access the cache(s) will result in a message indicating that the cache is "[INVALID/CORRPUTED]". Without the patch, the message "crash: unable to initialize kmem slab cache subsystem" is displayed during session initialization, and run-time commands that attempt to access the kmem slab cache subsystem fail with the error message "kmem cache slab subsystem not available". (anderson@redhat.com) - Fix for the "kmem -[sS] <slab-object-address>" option in Linux 3.6 and later kernels configured with CONFIG_SLAB. Without the patch, the command fails with the message "kmem: address is not allocated in slab subsystem: <slab-object-address>. This also causes the "kmem <slab-object-address>" command to (quietly) fail to determine that the address is a slab object. (anderson@redhat.com) - Fix for the "bt" command if a kernel __init text address is encountered. Without the patch, and depending upon the reallocation of the __init text memory, a bogus framesize may be calculated, or more likely, in a compressed kdump, a warning message indicating "bt: page excluded: kernel virtual address: <address> type: gdb_readmem_callback" will be displayed following the frame data. (anderson@redhat.com) - Update for determining whether an S390X PTE contains a swap entry in Linux 3.12 and later kernels. (holzheu@linux.vnet.ibm.com) - Resurrected the translation and display of the page.flags bits by the "kmem -p" command on Linux 2.6.26 and later kernels whose vmlinux debuginfo data contains either the "pageflags" enumerator or the "pageflag_names" array of trace_print_flags structures. If they are not available, just the page.flags value is printed in hexadecimal, as has been done since Linux 2.4.9. (anderson@redhat.com) - Fix for the "bt" command when used with vmcore files that were created with the recently-introduced "virsh dump --memory-only", which dumps KVM guests into an ELF vmcore similar to those created by the kdump facility. Without the patch, a faulty backtrace for the panic task may be generated due to the use of incorrect starting RSP/RIP registers; this happens because (unlike kdump) the non-panicking cpus are offlined prior to the dumpfile being created, which in turn leads to the use of the wrong NT_PRSTATUS note. (anderson@redhat.com) - Fix for the CPU number display on systems with 255 or more cpus during the initial banner, by the "set" command, the "ps" command, and by all commands that display the per-task header consisting of the task address, pid, cpu and command name. Without the patch, for cpu 255, the "sys" command displays "NO_PROC_ID", and the other commands would show a "-" for the cpu number; for cpu numbers greater than 255, garbage values would be displayed in the cpu number field. (anderson@redhat.com) - Implemented support for compressed kdump header version 6, in which makedumpfile(8) adds new fields in the kdump_sub_header to support large memory systems with pfn values that are larger than 32-bits. Without the patch, if the system contains physical memory located in high memory such that its maximum pfn value is overflows the 32-bit "max_mapnr" field in the header, the crash session will fail with the error message "crash: vmlinux and vmcore do not match!". (jingbai.ma@hp.com) - Fix for the "net -s" command on Linux 3.8 and later kernels. Without the patch, the command fails with the message "net: invalid structure member offset: inet_opt_daddr". (anderson@redhat.com) - Fix a build failure in a native ARM64 environment due to obsolete LKCD dumpfile headers. (anderson@redhat.com) - Implementation of a new "per-cpu object" as an argument format that can be passed to the "p", "struct", "union" or "*" commands. The format is expressed as either <per-cpu symbol>:<cpu-specifier> or as <per-cpu offset>:<cpu-specifier>, where the per-cpu symbol or per-cpu offset must precede a colon, and where the <cpu-identifier> follows the colon. The cpu-identifier may be expressed in any of the following manners: : CPU of the currently selected task. :a[ll] all CPUs. :#[-#][,...] CPU list(s), e.g. "1,3,5", "1-3", or "1,3,5-7,10". Without the patch, per-cpu symbols are only accepted by the "p" command, and the data type and the resolved kernel virtual address for each per-cpu instance are displayed shown. With this patch, a colon and a cpu-specifier may be appended to the symbol name, and the the contents of the symbol on each cpu that is specified will be displayed by the "p" command. For the "struct/union/*" commands, an argument may be specified using either a per-cpu offset value or per-cpu symbol name followed by a colon and cpu-specifier, and the contents of each structure/union on each specified cpu will be displayed. (ptesarik@suse.cz) Fixed several minor flaws that were detected by a Coverity Scan: tools.c: 992:warning[invalidScanfArgType_int] – %d in format string (no. 1) requires 'int *' but the argument type is 'unsigned int *'. memory.c: 7461:error[uninitvar] – Uninitialized variable: page_cache_size filesys.c: 731:error[resourceLeak] – Resource leak: version kernel.c: 5675:error[uninitvar] – Uninitialized variable: action 7799:error[memleakOnRealloc] – Common realloc mistake: 'ikconfig_all' nulled but not freed upon failure configure.c: 793:error[mismatchAllocDealloc] – Mismatching allocation and deallocation: fp remote.c: 1120:error[resourceLeak] – Resource leak: pipe va_server.c: 316:error[memleak] – Memory leak: disk_hdr va_server_v1.c: 311:error[memleak] – Memory leak: disk_hdr makedumpfile.c: 80:error[memleakOnRealloc] – Common realloc mistake: 'ptr' nulled but not freed upon failure sadump.c: 231:error[memleakOnRealloc] – Common realloc mistake: 'sdh' nulled but not freed upon failure extensions/snap.c: 550:error[uninitvar] – Uninitialized variable: prstatus_len 541:error[uninitvar] – Uninitialized variable: l_offset extensions/trace.c: 1477:error[resourceLeak] – Resource leak: file (anderson@redhat.com) ------------------------------------------------------------------- Fri Sep 13 07:20:59 UTC 2013 - ptesarik@suse.com - crash-crosscrash-hint.diff: Removed, because crosscrash isn't maintained any longer. ------------------------------------------------------------------- Thu Sep 12 19:03:05 UTC 2013 - dmair@suse.com - Implementation of v7.0.2 from upstream. o See http://people.redhat.com/anderson/crash.changelog.html for a complete list of changes from 6.1.3. - crash-rl_digit_loop-return.patch - removed - crash-missing-declarations.patch - refreshed - crash-rl_digit_loop-return.patch - refreshed - eppic-switch-to-system-lib.patch - refreshed ------------------------------------------------------------------- Fri May 10 21:56:52 UTC 2013 - dmair@suse.com - Implementation of v6.1.3 from upstream. crash-display-date-fix.patch - removed/redundant crash-kmem_cache_slab.patch - removed/redundant crash-siginfo.patch - removed/redundant crash-var_length_log_rec.patch - removed/redundant eppic-switch-to-system-lib.patch - Implementation of EPPIC via system library rather than retrieve and include in build.

Comment from tabraham follows: - added crash-display-date-fix.patch This is a backport of the fix from crash-6.0.9 to fix the date displayed by the initial system banner and by the "sys" command for linux kernel 3.6 and later. Without the patch, the date displayed will be that of the UNIX epoch adjusted to local time. - added crash-kmem_cache_slab.patch This is a backport of the fix from crash-6.1.0 for Linux 3.0 and later kernels that have been configured with CONFIG_SLAB and with- out CONFIG_NODES_SHIFT. Without the patch, the warning messages "crash: nr_node_ids: symbol does not exist" and "crash: unable to initialize kmem slab cache subsystem" are displayed during initialization, and the "kmem -[sS]" options fail with the message "kmem: kmem cache slab subsystem not available". ------------------------------------------------------------------- Mon Feb 4 18:47:06 UTC 2013 - dmair@suse.com - crash-compressed-booted-kernel.patch: Fix for "crash when invoked without arguments fails to analyze the live system" (bnc#777516). ------------------------------------------------------------------- Fri Jan 25 20:33:38 UTC 2013 - tabraham@suse.com - crash-var_length_log_rec.patch: support variable-length record kernel log buffer present in kernel 3.5 and later (bnc#796151). ------------------------------------------------------------------- Sun Jul 29 07:04:13 UTC 2012 - aj@suse.de - Fix build with glibc 2.16 (struct siginfo -> siginfo_t). ------------------------------------------------------------------- Tue Jul 17 16:52:55 UTC 2012 - dmair@suse.com - Enabled support for reading dumpfiles compressed by LZO using makedumpfile version 1.4.4 or later. ------------------------------------------------------------------- Fri Jun 1 09:20:03 UTC 2012 - dmair@suse.com - Update to crash 6.0.7 from upstream and adjust patches to apply without offsets. Upstream changes: o Enhanced the search command to allow the searched-for value to be entered as a crash (expression) or a kernel symbol name. The resultant value of an (expression) or kernel symbol value must fit into in the designated value size if -w or -h are used, and neither variant may be used with the -c option. If found, both the resultant value and the argument input string will be displayed next to the target address(es). o Added a new "search -t" option that will restrict the search to the kernel stack pages of all tasks. If one or more matches are found in a task's kernel stack, the output is preceded with a task-identifying header. o Fix for the s390x "bt -[tT]" options when run on an active task on a live system. Without the patch, the options fail with the message "bt: invalid/stale stack pointer for this task: 0". o Fix for s390x "vm -p" option, which may show invalid user to physical address translation data if a page is not mapped. Without the patch, a page's translation may indicate "<address> SWAP: (unknown swap location) OFFSET: 0", or show an incorrect swap offset on an actual swap device. o Added new "vm -[xd]" options to be used in conjunction with "vm -[mv]", which override the current default output format with hexadecimal or decimal format for just the command instance. Without the patch, it would require changing the default output format with "hex" or "dec" prior to executing "vm -[mv]". The new flags may also be used with "foreach vm -[mv]". o Fix for the s390x "vm -p" and "vtop -u <user-address>" commands if the page containing the relevant PTE is not mapped. Without the patch, the commands fail with the error message "vm: read error: kernel virtual address: 0 type: entry" or "vtop: read error: kernel virtual address: 0 type: entry" o Fix for the s390x "vm -p" command and "vtop -u <user-address>" commands to properly translate pages that are swapped out into their swap file and offset. Without the patch, the swap file and offset would not be displayed. o Added new "list -[xd]" options to be used in conjunction with "list -s", which override the current default output format with hexadecimal or decimal format for just the command instance. Without the patch, it would require changing the default output format with "hex" or "dec" prior to executing "list -s". o Added new "net -[xd]" options to be used in conjunction with "net -S", which override the current default output format with hexadecimal or decimal format for just the command instance. Without the patch, it would require changing the default output format with "hex" or "dec" prior to executing "net -S". The new flags may also be used with "foreach net -S". o Added new "mach -[xd]" options to be used in conjunction with "mach -c", which override the current default output format with hexadecimal or decimal format for just the command instance. Without the patch, it would require changing the default output format with "hex" or "dec" prior to executing "mach -c". o If the value read from the cpu online, present, or possible masks contains a cpu bit value that is outside the architecture's maximum NR_CPUS value, print a warning message during invocation. Without the patch, a corrupt vmcore containing a bogus mask value could quietly corrupt heap memory. o Add support to for reading dumpfiles compressed by LZO using makedumpfile version 1.4.4 or later. This feature is disabled by default. To enable this feature, build the crash utility in the following manner: (1) Install the LZO libraries by using the host system's package manager or by directly downloading libraries from author's website. The packages required are: - lzo - lzo-minilzo - lzo-devel The author's website is: http://www.oberhumer.com/opensource/lzo (2) Create a CFLAGS.extra file and an LDFLAGS.extra file in top-level crash sources directory: - enter -DLZO in the CFLAGS.extra file - enter -llzo2 in the LDFLAGS.extra file. (3) Build crash with "make" as always. * Only available as a source option for manual build in this environment o Fix for the included "trace" extension module. Without the patch, if the module initialization sequence fails, a double-free in the module may lead to a subsequent malloc() segmentation violation in the crash session. o Incorporated the "ipcs" extension module written by Qiao Nuohan as a built-in command. The command displays the kernel's usage of the System V shared memory, semaphore and message queue IPC facilities. It differs from the original extension module by fixing a failure scenario if the current task is exiting, and adds a "-n pid|task" option, which displays the IPCS facilities with respect to the namespace of a given pid or task. o Fix for a gdb-7.3.1 regression that causes the line number capability to fail with certain ranges of x86 base kernel text addresses. Without the patch, the "dis -l <symbol>" or "sym <symbol>" commands would fail to show line number information for certain ranges of base kernel text addresses. o Added a new "printm" command to the embedded gdb module. It is currently only used by the "pstruct" extension module, but can be used to dump the type, size, offset, bitpos and bitsize values of an expression. o Added a new "runq -t" option that displays the timestamp information of each cpu's runqueue, which consists of either the rq.clock, the rq.most_recent_timestamp or rq.timestamp_last_tick value, whichever applies. Following each cpu timestamp is the last_run or timestamp value of the active task on that cpu, whichever applies, along with the task identification. o Fix for an initialization-time warning when running on a live system with the most recent version of the modprobe command, which no longer supports the -l and --type options. The modprobe is used to detect whether the crash.ko memory driver is part of the distribution. Without the patch, a warning message is issued that indicates "/sbin/modprobe: invalid option -- 'l'". If the driver is built into the kernel, the message is harmless. If the driver is not built into kernel, then the crash.ko (/dev/crash) driver would not be selected as the live memory source. ------------------------------------------------------------------- Thu May 17 07:54:29 UTC 2012 - ptesarik@suse.cz - delete crash-foreach-match-running.patch: upstream ------------------------------------------------------------------- Mon May 14 20:24:51 UTC 2012 - dmair@suse.com - Update to crash 6.0.6 from upstream o Extend the supported cross-architecture build capability so that it applies to the SIAL extentension module. Without the patch, when building the SIAL module an environment where the overlying crash utility was built with "make target=ARM", "make target=PPC", or "make target=X86", the SIAL extension module would continue to be built for the host architecture o Fixes for memory leaks and possible segmentation violations when unloading SIAL extension module scripts. o Fix for the new "foreach RU" task state qualifier. Without the patch, the runnable tasks are not selected. o Fix to disallow multiple task states from being entered using the "foreach <task-state>" qualifier. Without the patch, if multiple states were entered, the last one on the command line would be honored. o Fix for the "extend" command to allow the usage of 32-bit PPC extension modules. Without the patch, the command fails with the message: "extend: <object>.so: not an ELF format object file". o If an input line starts with "#" or "//", then the line will be saved as a comment that is visible when re-cycling through the command history list. o Fix for a crash-5.1.9 regression that broke the "bt -g" option. Without the patch, the option is ignored completely. o Fix for s390x virtual-to-physical translation of virtual addresses that are backed by 1MB pages. o The s390x has a dumpfile method that creates "live dumps", where the kernel continues to run while the dumpfile is being created. The initial system banner display and the "sys" command will inform the user that the dumpfile is a "[LIVE DUMP]", and the "bt -a" option will fail with the message "bt: -a option not supported on a live system or live dump". o Newly-created dumpfiles generated by the "snap.c" extension module will now be recognized as "live dumps". Accordingly, the initial system banner display and the "sys" command will inform the user that the dumpfile is a "[LIVE DUMP]", and the "bt -a" option will fail with the message "bt: -a option not supported on a live system or live dump". o If "bt" alone is attempted on an active task in a "live dump", it will indicate "(active)", i.e., the same as if it were attempted on a live system. o If an extension module does not define the appropriate architecture, i.e., "-DX86", "-DX86_64", etc., then the inclusion of "defs.h" will generate a compiler failure indicating "error: 'NR_CPUS' undeclared here (not in a function)". In that case, the architecture will now default to that of the host machine. o Prevent a highly-unlikely incorrect calculation of the maximum cpudata array length of a kmem_cache during initialization of of CONFIG_SLAB kernels. o Prevent an infinite loop during the initialization of the kmem_cache subsystem in CONFIG_SLAB kernels if the cache list or the vmcore is corrupt. If the kmem_cache list links back into itself, messages showing the first "duplicate" entry in the list and "crash: unable to initialize kmem slab cache subsystem" will be displayed. o Update to the "mod" command to additionally search for module object files in the directory containing the kernel namelist (vmlinux) file. This will allow an alternate module-debuginfo directory tree to be set up like so: # cd <directory> # rpm2cpio kernel-debuginfo-<release>.rpm | cpio -idv Having done that, and by referencing the vmlinux file in that directory tree directly or by symbolic link, the "mod" command will search for module object files starting from the directory containing the vmlinux file if they are not found in the standard /lib/modules/<release> directory. o Update to the s390x "bt" command if a task was running in userspace. Without the patch, the back trace display ended at the kernel entry function frame; with the patch, the user space PSW register is displayed with a "(user space)" tag, followed by the general purpose register set. o In the unlikely event that the access of ARM or x86_64 kernel unwind table data fails during crash invocation, print a warning message and allow the crash session to continue. Without the patch, the crash session would fail immediately. ------------------------------------------------------------------- Tue Mar 27 16:30:23 UTC 2012 - dmair@suse.com - Update to crash 6.0.5 from upstream and adjust patch positions to match current crash source. 6.0.5 changelog is: o Enhancement to the "foreach" command to allow any of the "name" arguments to be POSIX extended regular expressions. The expression string must be encompassed by "'" characters, and will be matched against the names of all tasks. o Fix for the embedded gdb module's "ptype" command, and by extension, the crash utility's "struct" command, to be able to fully display embedded structure or union members of a structure/union. Without the patch, if a structure or union is a member of a structure or union that is a member of a structure or union, then it is displayed as "struct {...}" or "union {...}". o Extend the "ps -l" output to also display the task state next to its last_run/timestamp value. o Enhancement to the "foreach" command which adds a new "state" task-indentifier argument that filters tasks by their task state. The state argument may be any of the task states displayed by the "ps" command: RU, IN, UN, ST, ZO, SW or DE. o Implemented a new pc->cmd_cleanup function pointer and an optional pc->cmd_cleanup_arg argument that will allow any command to register a function and an optional argument that will be called after a command has completed successfully, or more likely, unsuccessfully. Normally the only cleanup required for a command is the freeing of buffers that were allocated with GETBUF(), but that is performed automatically after each command is run. However, with the introduction of the new POSIX regular expression functionality of the "foreach" command, there needed to be a way to call regfree() in the case where where regcomp() was called successfully, but then the command later encountered one of several fatal error conditions. This facility is also available for use by extension module commands. o Enforce the usage of a kernel thread's pgd from its active_mm for the ARM "vtop -c" command; if its active_mm is NULL, make the command fail similarly to the other architectures, displaying the error message "vtop: no active_mm for this kernel thread". o Fix for the x86_64 "bt" command running against recent kernels if an active task was operating on its IRQ stack when the crash occurred. Without the patch, the determination of the IRQ exception frame was off-by-8, displaying invalid register data and the error message "bt: WARNING: possibly bogus exception frame". o Update to handle the vfsmount structure change in 3.3 kernels, in which most members of the vfsmount structure have been moved into a new "struct mount", and the vfsmount structure has been embedded in the new mount structure. Without the patch, the following commands will fail, displaying the following error messages: mount: "mount: invalid structure member offset: vfsmount_mnt_list" files: "files: invalid structure member offset: dentry_d_covers" vm: "vm: invalid structure member offset: dentry_d_covers" swap: "swap: invalid structure member offset: dentry_d_covers fuser: "files: invalid structure member offset: dentry_d_covers" The "fuser" command generates the above error because it uses the "files" command behind the scenes. o Fix for the "ps" command to prevent the display of "??" under the ST (task state) column. Without the patch, in more recent kernels, if more than one bit were set in the task_struct.state field, the state would display "??". With the fix, the primary state will always be displayed. o Update to the output of the "set" command when it displays a task's state. Without the patch, if more than one bit was set in the task_struct.state field, "STATE: (unknown)" would be displayed. With the fix, all bits in both the task_struct.state and task_struct.exit_state fields are translated. o Implemented a new "vm -P <vma-address>" option, which is similar to "vm -p", but only does the page translations of the specified VM area of a context. o Add support for the Freescale PowerPC e500mc version of the E500 processor chipset, and rework the PPC platform-specific code in order to more easily support new processors. o Implemented a new "gdb" crash environment variable that can be used to alter a crash session's behavior such that all commands are passed directly to the embedded gdb module. The new mode is turned on and off by entering "set gdb on" and "set gdb off". When running in this mode, the command prompt will be "gdb>". In order to execute native crash commands while running in this mode, precede the command with the "crash" directive, for example, "crash ps". o Fix for a "*** stack smashing detected ***: crash terminated" failure during the initial system banner display on a 32-bit PPC platform. o Redesigned/simplified the internal read_string() function to prevent a potential segmentation violation. o Updates for the 32-bit PPC "vtop" command output: (1) Translate kernel virtual addresses for FSL BOOKE by using the TLBCAM setting (2) Remove the PMD line from the display (3) Fix the displayed PHYSICAL values of FSL BOOKE PTE format o Fix for crash invocation failure on 3.3-era kernels in which the former standalone "xtime" timespec structure has been moved into the "timekeeper" structure. Without the patch, the crash session would fail early on with the message "crash: cannot resolve: xtime". The patch also prevents the crash session failure in the unlikely event that the timespec access fails. ------------------------------------------------------------------- Wed Feb 29 22:12:17 UTC 2012 - dmair@suse.com - Update to crash 6.0.4 from upstream and adjust patch locations to match current crash source. 6.0.4 changelog is: o Fix to allow the recently-added "mod -g" and "mod -r" options to be used together. o Additional update for 3.1.x and later kernels configured with CONFIG_SLAB, which have replaced the kmem_cache.nodelists[] array with a pointer to an outside array. o Document the "crash [-h|--help] all" option in the crash.8 man page and in the "crash [-h|--help]" output. o Fix the S390/S390X-specific "s390dbf" command's "hex_ascii" debug data printing routine to prevent the display of non-ASCII characters. o Fix for ARM stack unwinding on 3.2 and later kernels due to commit: http://git.kernel.org/linus/de66a979012dbc66b1ec0125795a3f79ee667b8a o Implemented a new "search -x <count>" option that displays the memory contents before and after any found search target. o Fix for the x86_64 Xen hypervisor "bt" command. Without the patch, the contents of the RDX register in exception frames incorrectly shows the contents of the RCX register. o Implementation of a platform-based vmalloc address translation scheme for the 32-bit PPC architecture, introducing suppport for the PPC44X platform while maintaining the current default platform. o Fix for the usage of native gdb commands where the command output is redirected to a pipe and then redirected to a file. o Fix to prevent a crash session that is run over a network connection that is killed/removed from going into 100% cpu-time loop. o Fix for the support of PPC64 compressed kdumps, a regression that was introduced in crash-6.0.3 when support for 32-bit PPC compressed kdumps was implemented. o Fix for the x86_64 "bt" command to prevent the possible skipping of the stack frame just above an exception frame that indicates "[exception RIP: unknown or invalid address]". Patches with modified target locations are: crash-make-emacs-default.diff crash-sles9-time.patch crash-crosscrash-hint.diff crash-missing-declarations.patch ------------------------------------------------------------------- Tue Feb 7 16:31:37 UTC 2012 - dmair@suse.com - Update to crash 6.0.3 from upstream and modifications to compile. 6.0.3 change log is: o Fix to gdb-7.3.1/bfd/bfdio.c to properly zero out a complete struct stat with a corrected memset argument o Fix for the SIAL extension module to remove a call to sial_free() for an uninitialised variable o Fix for the "runq" command for kernels that are configured with CONFIG_FAIR_GROUP_SCHED o Implemented build and code for the analysis of 32-bit PPC ELF kdump vmcores o Implemented the capability of building a PPC crash binary on a PPC64 host, which can be done by entering "make target=PPC" o Determine the PPC page size from the kdump PAGESIZE vmcoreinfo data o Fix for the "kmem -[sS]", "kmem -[fF]" and "kmem <address>" options in 3.2 kernels o Addition of a set of dumpfile read diagnostic debug statements o Fix for X86 kernels that have CONFIG_X86_32, CONFIG_DISCONTIGMEM, CONFIG_DISCONTIGMEM_MANUAL and CONFIG_NUMA all configured o Fix for the "vtop" command on large NUMA X86 kernels where a node's starting physical address is larger than 32-bits o Update for the ARM architecture to recognize a recent change of its vmlinux section name from ".init" to ".init.text" o Significant speed increase of the "kmem -p" command, especially on large-memory systems o Implemented new "irq -a" and "irq -s" options o Removal of a redundant read of the kernel's __per_cpu_offset pointers in the ARM architecture's arm_get_crash_notes() function o Fix for an ARM architecture segmentation violation because of a stack overflow due to recursion in the page table translation code o Fix for the the "FREE HIGH" tally in the X86 "kmem -i" display o Fix for the "kmem -n" output display for 32-bit architectures that are configured with CONFIG_SPARSEMEM o Cleanup of several SIAL extension module files to address bison 2.5 and gcc 4.4.3 compile-time warnings o Fix for "net -[sS]" command options on the ARM architecture o Fix for the ARM "bt" command to allow the core kernel unwind tables to be used in cases where the module unwind tables are inaccessible o Implementation of a new "dev -d" option that displays disk device I/O statistics o Update for 3.1.x and later kernels configured with CONFIG_SLAB, which have replaced the kmem_cache.nodelists[] array with a pointer to an outside array o Implemented build and code for analysis of 32-bit PPC compressed kdump vmcores o Prevent the "runq" command from dumping an unending loop of tasks if the CFS runqueue has been corrupted o Repurposed/renamed the rarely-used and rarely-needed "mod -r" option to "mod -R" o Implemented a new "mod -r" option, which will pass the "-readnow" flag to the embedded gdb module, which will override the two-stage strategy that it uses for reading symbol tables from module object files o Performance increase for the "kmem -s <address>" option on kernels configured with CONFIG_SLAB, most notably on kernels whose kmem_cache.array[NR_CPUS] array is several pages in size o Require that the "<slabname>" argument to "kmem -s <slabname>" be escaped with a '\' character in two situations: (1) in the highly-unlikely case of a kmem_cache slab named "list", to prevent the ambiguity with the "kmem -s list" command option. (2) if the first character of the <slabname> actually is a '\' character Modifications to compile are as follows: o Replacement of crash-6.0.2.tar.gz with crash-6.0.3.tar.gz o Remove crash-wrong-memset.patch the fix is present in 6.0.3 o Remove crash-add-read-diags.patch the change is in 6.0.3 ------------------------------------------------------------------- Mon Jan 9 22:05:10 UTC 2012 - ptesarik@suse.cz - crash-wrong-memset.patch: fix compilation on SLE11. ------------------------------------------------------------------- Thu Jan 5 17:14:24 UTC 2012 - dmair@suse.com - Update to crash 6.0.2 from upstream and modifications to compile. ------------------------------------------------------------------- Tue Dec 27 12:46:46 UTC 2011 - idonmez@suse.com - Fix wrong size parameter in memset call ------------------------------------------------------------------- Mon Nov 7 20:16:26 UTC 2011 - dmair@suse.com - Update to crash 6.0.0 from upstream and modifications to compile. ------------------------------------------------------------------- Thu Oct 13 13:39:36 UTC 2011 - ptesarik@suse.cz - crash-debuginfo-compressed.patch: Search debuginfo files in the same directory as the original gzipped kernel image (bnc#723639). ------------------------------------------------------------------- Tue Oct 11 13:24:38 UTC 2011 - ptesarik@suse.cz - Add Requires: kernel-$flavor to new-style KMP packages. - Provide old-styl crash-kmp (for SLES9). ------------------------------------------------------------------- Mon Oct 10 16:04:01 UTC 2011 - ptesarik@suse.cz - Build the crash memory driver kernel module as a KMP. ------------------------------------------------------------------- Mon Oct 10 15:48:55 UTC 2011 - ptesarik@suse.cz - Change the license from GPLv3 (only) to GPLv3 or higher. ------------------------------------------------------------------- Thu Sep 22 19:02:09 UTC 2011 - lchiquitto@suse.com - Add the gcore extension as a subpackage for i386 and x86_64.

Use opt as a replacement (bnc#612128). - crash-xen_virt_start.patch: account for the changed value of XEN_VIRT_START in Xen-4.0.0 (bnc#612128). - crash-xen-per_cpu_shift.patch: correctly determine PERCPU_SHIFT for Xen syms (bnc#612128). ------------------------------------------------------------------- Mon Jan 3 20:09:41 UTC 2011 - dmair@novell.com - Update to 5.1.1 o Fix for the potential to miss tasks when walking the pid_hash table in 2.6.24 and later kernels. Without the patch, the task will simply not be seen in the gathered task list. o 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. o 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. o 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. o 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. o 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. o Enhancement of the "repeat" command to allow command aliases. o 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. o 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)". o 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. o 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. o 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. o 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, or "crash: /dev/crash: not a supported file format" if the driver is built into the kernel. o Fix for the ARM "bt" command to address the issue behind faulty warning messages that indicate "WARNING: UNWIND: unsupported personality routine". o Fix for the ARM "bt" command to address the issue behind faulty warning messages that indicate "bt: WARNING: UNWIND: cannot find index for <address>". ------------------------------------------------------------------- Mon Dec 13 20:06:50 UTC 2010 -
