GFDL-1.2-only
* Mon Nov 20 2023 dmair@suse.com
- Tidy patches to apply without offsets to crash 8.0.4/gdb 10.2:
- crash-allow-use-of-sadump-captured-KASLR-kernel.patch
- crash-debuginfo-compressed.patch
- crash-make-emacs-default.diff
- crash-sles9-time.patch
- crash-stop_read_error_when_intent_is_retry.patch
- crash-usrmerge.patch
* Thu Nov 16 2023 dmair@suse.com
- Update to crash-8.0.4
- Removed patches already present in upstream source:
* crash-fix-glibc-redefs.patch
* crash-get-linux_banner-without-using-syment-type.patch
- Removed the redundant clean section from the spec file
* Thu Oct 05 2023 dmair@suse.com
- Updated crash gcore extension to current upstream v1.64 dated
2023-02-28. It's not updated in each product version and most
don't release a crash-gcore rpm now but updated the latest
openSUSE package project at this time.
* Wed Sep 20 2023 dmair@suse.com
- On initialization crash verifies the core based on the text
referenced by the linux_banner symbol in the supplied core. It
chooses how to get the address of the text based on the symbol
type decoded with gdb. For some compressed kernels with an
accessible debuginfo file the type is not supported (bss segment
found, data reference expected) but the symbol and it's value are
valid. This causes the linux_banner text to be used as the
"address" of the linux_banner and that's an invalid address for
the coredump causing crash to fail to load reporting something
like:
WARNING: invalid linux_banner pointer: 65762078756e694c
where the address is obviously ASCII text used as a number. A
SUSE patch to support compressed kernel binaries introduces the
behavior, it does not happen for upstream crash source as-is. The
difference is whether the symbol details are obtained from the
kernel binary or debuginfo (fails for some debuginfos).
* crash-get-linux_banner-without-using-syment-type.patch
In verify_version(), choose how to obtain the linux_banner address
based on the result of get_symbol_type() instead. TYPE_CODE_ARRAY
causes the value of the symbol obtained from gdb to be used.
TYPE_CODE_PTR causes the sybol data to be read to get the address.
Default is unrecognized type but a warning is shown and the value
obtained from gdb used as a best case choice.

* Tue Aug 15 2023 dmair@suse.com
- crash has it's own definitions of some glibc functions, including
strlcpy(), length limited string copy. In glibc 2.38 the second
argument is const char *, in crash it is char *. The argument is
the source string to copy from and shouldn't be modified. crash
uses the glibc version in some places, it's own in others and the
declarations are incompatible resulting in build errors. Added
* crash-fix-glibc-redefs.patch
to make the crash declaration of strlcpy() match the glibc 2.38
version. It may also need to be made product version conditional
but it should fix Factory.

the extension can be used for diagnosing kernel trace data.
* Mon Dec 05 2022 lnussel@suse.de
- BuildRequire %kernel_module_package_buildreqs (boo#1205149)
* Fri Nov 18 2022 ptesarik@suse.com
- Require zlib-devel for crash-devel.
* Tue Oct 25 2022 dmair@suse.com
- make of crash extensions was failing due to extension shared
objects depending on extension source file plus defs.h. defs.h is
hardlinked from the crash base source directory before the .so
make rule but make reports it doesn't know how to make requirement
defs.h. I added a rule for defs.h in the extensions Makefile that
creates defs.h the same way as was previously used but satisfies
the dependency resolution on demand then the make succeeded.

- Kernel commit 5c83511bdb9832c86be20fb86b783356e2f58062 removed
pv_init_ops, and commit 054ac8ad5ebe4a69e1f0e842483821ddbe560121
removed the Xen-specific paravirt patch function. As a result,
pvops Xen dumps are no longer recognized as Xen dumps, and
virtual-to-physical translation fails.
Use the value of xen_start_info to determine whether the kernel
is running in Xen PV mode. As suggested by Juergen Gross.

* Mon Dec 07 2020 dmair@suse.com
- Corrected project URL in spec file to match the changed upstream
location as-of May 30th 2020.
Noted the project URL change in README.SUSE without removing the old URL
because it represents the location the project source was obtained from.
The next project source update is available from the new project URL. When
the package is updated with that source all URL project references will be
modified to only show the new URL.
Add crash-update-whitepaper-URL.patch
Note change of no longer valid old project whitepaper URL to current valid
project whitepaper URL in help output. Leave the old one reported because it
represents the location the project source was obtained from for this
package version.

* Fri Oct 09 2020 guillaume.gardet@opensuse.org
- Fix build on aarch64:
crash-gdb-fix-aarch64.patch
* Wed Sep 09 2020 dmair@suse.com
- Add crash-verify-exception-frame-accessible-for-all-verify-requests.patch
In calls to search a stack for x86_64 exceptions a flag is used
to request the stack be verified for room to contain saved
registers. The verify is not performed if other flags are used
in the same call. Fixing this exposes another bug where only a
kernel stack is verified anyway, even if the exception is being
searched for on a userspace stack. Patch fixes both problems.

Fix integer overflow with large memory configuration (bsc#1168233 ltc#184660).
* Tue Feb 04 2020 dmair@suse.com
- Upgraded the source to version 7.2.8. The previous version was
modified to support newer kernels used in SLE-15-SP2 but was not
complete.
* Includes a fix for kernels that contain:
e0703556644a531e50b5dc61b9f6ea83af5f6604
which introduces symbol namespaces. Without the change then
depending on architecture:
(1) the kernel module symbol list will contain garbage
(2) the session fails during initialization with a dump of
the internal buffer allocation stats followed by the
message "crash: cannot allocate any more memory"
(3) the session fails during initialization with a
segmentation violation (bsc#1162064)
* Includes the merge of the S390x patches since crash 7.2.7
(bsc#1156645/bsc#1161640)
* Source already includes XZ compressed module support, removed:
crash-symbols-add-support-for-XZ.patch
* Refreshed patches that were no longer aligned with source:
crash-allow-use-of-sadump-captured-KASLR-kernel.patch
crash-s390-autodetect-kaslr.patch
crash-sles9-time.patch
* Fri Jan 10 2020 dmair@suse.com
- Upgraded the source tarball to version 7.2.7. This is required
to support coredumps from currently used kernel versions in the
product (bsc#1159686).
- droped the patch obsoleted due to already being present in the
new source:
* crash-allow-kmem-section-is-early.patch
* Tue Nov 12 2019 dmair@suse.com
- Added commit c0371f6ee2cae31ec9f506bbd231ab8fbe334c13 - Fix to
allow live analysis of s390x kernels that have been configured
with CONFIG_RANDOMIZE_BASE=y (KASLR). This allows crash to load
the coredump without the need for "--kaslr=<offset> on the
command-line.
Added:

bsc#1073993
* Fri Jan 12 2018 dmair@suse.com
- Added crash-ppc64-ensure-chosen-stack-symbol-relates-to-an-actual-backtrace.patch
With latest NMI IPI changes, crash_ipi_callback is found multiple
times on the stack. Ensure the chosen symbol relates to an actual
backtrace. bsc#1072718
* Thu Dec 07 2017 dimstar@opensuse.org
- Escape the usage of %{VERSION} when calling out to rpm.
RPM 4.14 has %{VERSION} defined as 'the main packages version'.
* Wed Nov 29 2017 dmair@suse.com
- Added crash-x86_64_kvtop-usable-symtab_init.patch to change
x86_64_kvtop() so that it can be called during symtab_init()
Added crash-allow-use-of-sadump-captured-KASLR-kernel.patch to
allow use of dumps of KASLR enabled kernels that were captured
by sadump.
Both are bsc#1070278/FATE#323473
* Tue Nov 14 2017 dmair@suse.com
- Upgrade the source tarball to version to 7.2.0 which requires the
removal of patches that are then already applied:
crash-gdb-add-proc_service-sync-with-GLIBC.patch
crash-xen_add_support_for_domU_with_linux_kernel_from_3.19.patch
A complete changelog is available via the crash source page at:
http://people.redhat.com/anderson/crash.changelog.html
Added crash-ppc64-book3s-update-hash-page-table-geometry.patch
from hbathini@linux.vnet.ibm.com via bsc#1067702 to correct
errors with virtual-to-physical address translation in the larger
virtual address range of newer kernels.
Added a BuildRequires of libelf that will populate the build
workspace with libelf (from elfutils) even though it is not
directly required by crash but is required by gdb (which crash
nests). It no longer got picked up automatically for build and
gdb and kernel module features had build errors before it.
* Fri Jun 09 2017 dmair@suse.com
- crash-xen_add_support_for_domU_with_linux_kernel_from_3.19.patch:
Since linux kernel 3.19 crash readmem() can't be used to read
xen_p2m_addr associate memory directly during m2p translation.
PV domU p2m mapping is also stored at xd->xfd + xch_index_offset
and organized as struct xen_dumpcore_p2m. This patch implements
a special reading function read_xc_p2m() to extract the mfns
from xd->xfd + xch_index_offset and makes and crash support Xen
PV domU dumpfiles for kernel 3.19 and later (bsc#1043501).
- add crash-xen_add_support_for_domU_with_linux_kernel_from_3.19.patch
* Fri Jun 02 2017 msuchanek@suse.com
- Merge SLE changes into Factory (bsc#1041638)
* Thu May 25 2017 dmair@suse.com
- crash-stop_read_error_when_intent_is_retry.patch: When reading a
memory image fails it may not be an error if it is still possible
to switch image and retry the read. Fix the error message output
to only occur if no retries are intended (bsc#1038839).
- add crash-stop_read_error_when_intent_is_retry.patch
* Mon Apr 24 2017 astieger@suse.com
- Exclude openSUSE from RT KMP build (bsc#1013843)
* Tue Mar 28 2017 dmair@suse.com
- crash source nests gdb source but gdb has a new build error on
Factory due to the bug and build environment modifications. The
fix is upstream gdb but not upstream crash's gdb.
Created crash patch:
crash-gdb-add-proc_service-sync-with-GLIBC.patch
to create the gdb patch in expanded crash and added to the gdb
Makefile patch it's application. Resolves the build error.
* Tue Mar 07 2017 dmair@suse.de

+ crash-Fix-for-the-PPC64-bt-command-for-non-panicking-activ.patch
* Tue Jan 24 2017 dmair@suse.de
- Upgrade of source tarball to 7.1.7 from upstream, removal of
crash-kernel-4.7.patch (source includes it) and refresh of other
patches to align with the version. For a detailed changelog of
the source tarball see:
http://people.redhat.com/anderson/crash.changelog.html
Feature enhancements included from 7.1.6:
- Introduction of support for "live" ramdump files, such as those
that are specified by the latest QEMU version's mem-path
argument of a memory-backend-file object, e.g.:
$ qemu-kvm ...other-options... \
- object memory-backend-file,id=MEM,size=128m,mem-path=/tmp/MEM,share=on \
- numa node,memdev=MEM -m 128
and a live session run can be run against the guest kernel like so:
$ crash <path-to-guest-vmlinux> live:/tmp/MEM@0
- Implemented support for the redesigned ARM64 kernel virtual
memory layout that was introduced in Linux 4.6. Plus ARM64
support for 4k pages with 4-level page tables and 48 VA bits.
NB: On live systems automatic operation with Linux 4.6 ARM64
kernels requires that CONFIG_RANDOMIZE_BASE is not configured.
If it is configured then use with a live system requires two
- -machdep arguments, e.g.:
- -machdep phys_offset=<base physical address>
- -machdep kimage_voffset=<kernel kimage_voffset value>
- Improvement of the ARM64 bt -f display so that, for most cases,
the stack frame delimiter will be the location of the old FP
and LR pair.
- New bt -v option that checks all tasks for evidence of stack
overflows.
- Incorporation of an alternative stack backtrace mathod
accessed directly using bt -o and the default method can be
toggled between the two using bt -O.
- Fix for the case where the sym/dis commands fail for a symbol
name that is composed entirely of hexadecimal characters and
was previously interpreted as an address.
- Determine structure member data if the member is contained in
an anonymous structure or union (no longer necessary to use a]
discrete gdb "printf" command to find the offset of it).
- Session initialization speed up.
- Addition of "list -S" and "tree -S" options (similar to the -s
option of each command) where member values are read from
memory instead of being interpreting gdb output (much faster
behavior for 1-, 2-, 4- and 8-byte members).
- Fix to recognize x86_64 Linux 4.8-rc1 and later kernels that
are configured with CONFIG_RANDOMIZE_MEMORY.
- Support for PPC64 virtual address translation of radix MMU.
- Improvement of "dev -d" output to display I/O statistics for
devices that use the blk-mq interface.
Feature enhancements included from 7.1.7:
- Restore x86_64 "dis" command's symbol translation for call or
jump target addresses for kernels configured with
CONFIG_RANDOMIZE_BASE.
- Re-factor of the trace extension module to locate all of the
ftrace buffers and extracts data from each of them rather than
only the primary one.
- Support for s390x CONFIG_THREAD_INFO_IN_TASK configuration so
that "bt" command no longer shows incomplete output.
- Support for live ARM64 kernels from Linux 4.6 that have the
kernel image loaded anywhere in physical memory.
- Update of /dev/crash/kernel driver to v1.3 which adds support
Linux 4.6 and later ARM64 kernels configured with
CONFIG_HARDENED_USERCOPY and S390x kernels that use
xlate_dev_mem_ptr() and unxlate_dev_mem_ptr() rather than
kmap() and kunmap().
- refresh eppic-support-arm64.patch crash-debuginfo-compressed.patch

http://people.redhat.com/anderson/crash.changelog.html
- Refreshed patch series with some changes required to
adjust for git host changes in eppic-switch-to-system-lib.patch
* Wed May 27 2015 dmair@suse.com
- Upgrade to 7.1.1 from upstream. At the time of writing the only
published changelog was supplied by e-mail list and is as follows
- Fix for two minor issues with the "net" command. Without the patch,
the "net -a" option appends its correct output with the command's
"Usage:" message; and if either the "net -x" or "net -d" options are
used without also specifying "-s" or "-S", the error message would
indicate "net: illegal flag: 800000" or "net: illegal flag: 1000000"
instead of showing the command's "Usage:" message.
(anderson@redhat.com)
- If the kernel (live or dumpfile) has the TAINT_LIVEPATCH bit set, or
if the Red Hat "kpatch" module is installed, the tag "[LIVEPATCH]"
will be displayed next to the kernel name in the initial system
banner and by the "sys" command. This new tag replaces the
"[KPATCH]" tag that was introduced in crash-7.0.7.
(anderson@redhat.com)
- Addressed three Coverity Scan complaints in vmware_vmss.c:
50:leaked_storage: Variable "fp" going out of scope leaks the
storage it points to.
53:leaked_storage: Variable "fp" going out of scope leaks the
storage it points to.
256:warning: Use of memory after it is freed
(anderson@redhat.com)
- Remove the LKCD-only "propeller spinner" seen when a dumpfile read
requires more than 2048 page header accesses. This was put in place
because of the non-random-access design of LKCD dumpfiles. Without
the patch, the spinner display is intermingled with command output,
which complicates the parsing of the output.
(watters.sam@gmail.com)
- Fix to support the Linux version increment from 3 to 4. Without the
patch, both dumpfile and live sessions fail during initialization,
issuing the message "WARNING: kernel version inconsistency between
vmlinux and dumpfile" or "WARNING: kernel version inconsistency
between vmlinux and live memory", followed by the nonsensical fatal
error message "crash: incompatible arguments: vmlinux is not SMP --
vmcore is SMP" or "crash: incompatible arguments: vmlinux is not
SMP -- live system is SMP". To prevent unexpected kernel version
bumps in the future, support has been added for version 5.
(anderson@redhat.com)
- Add support for more than 16TB of physical memory space in the SADUMP
dumpfile format. Without the patch, there is a limitation caused
by several 32-bit members of dump_header structure, in particular
the max_mapnr member, which overflows if the dumpfile contains more
than 16TB of physical memory space. The header_version member of
the dump_header structure has been increased from 0 to 1 in this
extended new format, and the new 64-bit members will be used.
(d.hatayama@jp.fujitsu.com)
- Fix for command lines that are redirected to a pipe. Without the
patch, if an external piped-to command contains a quoted string that
includes a "|" character, the command fails with the message "crash:
pipe operation failed".
(anderson@redhat.com)
- Fix for insecure temporary file usage in _rl_tropen() as reported by
readline library CVE-2014-2524.
(anderson@redhat.com)
- When the gdb-<version>.patch file has changed and a rebuild is
done from within a previously-existing build tree, the "patch -N"
option is used to ignore patches that have been previously applied;
this patch also applies the "patch -r-" option to prevent unnecessary
.rej files from being created.
(anderson@redhat.com)
- Fix to account for Xen hypervisor's "domain" structure member name
change from "is_paused_by_controller" to "controller_pause_count".
Without the patch, in Xen 4.2.5 and later, the crash session fails
during initialization with the error message 'crash: invalid
structure member offset: domain_is_paused_by_controller".
(dietmar.hahn@ts.fujitsu.com)
- During initialization, reject useless ARM64 "(A)" and "(a)" absolute
symbols that are below the text region. Without the patch, several
recently-introduced absolute symbols have been introduced into the
kernel, which will be displayed by "sym -l" prior to the first kernel
virtual address symbol, and will show up in command output where
memory values are translated into kernel symbol references.
(anderson@redhat.com)
- Fix for ARM64 kernels to account for changes in the virtual memory
layout introduced in Linux 3.17. The vmalloc region end address, and
the vmemmap start and end addresses are now calculated at kernel
build time, because they depend upon the size of a struct page.
Accordingly, the crash utility needs to calculate those three address
values dynamically, after the embedded gdb module has initialized.
Without the patch, reads of page structures return invalid data due
to incorrect virtual-to-physical translations of memory in the
vmemmap range. This in turn causes commands that require page
structure contents to fail or show invalid data, such as "kmem -p",
"kmem -[sS]", and the "kmem -[fF]" options.
(anderson@redhat.com)
- Fix to support ELF vmcore dumpfiles whose PT_LOAD file offset values
of their respective memory segments are not laid out sequentially
from low to high in the dumpfile. This has only been seen in ELF
dumpfiles created by VMware's "vmss2core -M" facility. Without the
patch, the crash session may fail during initialization, either with
the message "cannot malloc ELF header buffer", or "crash: <dumpfile>:
not a supported file format".
(anderson@redhat.com)
- Enhancement to the support of VMware .vmss suspended state dumpfiles.
There may be holes in the memory address saved for PCI, etc. In such
cases, the memory dump is divided into regions. With this patch, up
to 3 memory regions are supported.
(hfu@vmware.com)
- Fortified the error handling of task gathering from the pid_hash[]
chains during session initialization. If a chain has been corrupted,
the patch prevents the sequence from entering an infinite loop, and
the error messages associated with corrupt/invalid chains have been
updated to report the pid_hash[] index number.
(anderson@redhat.com)
- Implemented a new STRDUPBUF() utility that will duplicate an existing
string into a buffer allocated with GETBUF(). As is the case with
any buffer allocated with GETBUF(), it is only meant to exist during
the life-span of the current command. If it is not explicitly freed
via FREEBUF(), then it will be freed automatically prior to the next
command.
(anderson@redhat.com)
- Implemented a new fill_struct_member_data() function that gathers
a bundle of data that describes a structure member. The function
receives a pointer to a struct_member_data structure, in which the
caller has initialized the "structure" and "member" name pointers:
struct struct_member_data {
char *structure;
char *member;
long type;
long unsigned_type;
long length;
long offset;
long bitpos;
long bitsize;
};
A gdb "printm" command is crafted using those two fields, and the
output of the command is used to initialize the remaining six fields.
Adapted from Qiao Nuohan's "pstruct" extension module.
(anderson@redhat.com, qiaonuohan@cn.fujitsu.com)
- Implemented a new "runq -c cpu(s)" option to display the run queue
data of specified cpus. It can be used in conjunction with all runq
command options. The cpus must be specified in a comma- and/or
dash-separated list; for examples, "3", "1,8,9", "1-23", or "1,8-15".
(anderson@redhat.com)
- Build extension modules that utilize the generic extensions/Makefile
with -g. In addition, build the snap.c extension module with -g.
(rabinv@axis.com)
- Several fixes, updates, and enhancements for 32-bit MIPS support:
(1) The MIPS general purpose registers in the elf_gregset_t
don't start at index 0 but at index 6.
(2) Adjust for the kernel's pt_regs structure changes between
kernel versions. For example, fields are inserted into the
middle based on build time options, and the amount of padding
at the head of the structure was changed relatively recently.
To handle this, split the structure definition into two parts
and get the offsets of these two parts dynamically.
(3) Do not display each parsed kernel symbol during initialization
when invoked with "crash -d8".
(4) Add support for loading raw MIPS ramdump dumpfiles.
(5) Add support for compressed kdump dumpfiles.
(rabinv@axis.com)
- Fix for a typo in "help foreach", and a fix for a spelling error in
"help input".
(weijg.fnst@cn.fujitsu.com)
- Fix for "and and" and "the the" typos in the README file.
(weijg.fnst@cn.fujitsu.com)
- Fix to address the Xen 4.5.0 hypervisor symbol name change from
"dom0" to "hardware_domain". Without the patch, the crash session
fails with the error message "crash: cannot resolve: dom0".
(dslutz@verizon.com)
- Fix for a regression in crash-7.1.0 that causes failures when the
"crash -t" option is run on a live system, and when analyzing remote
Linux kernels. Without the patch, "crash -t" on a live system fails
with the message "crash: cannot open remote memory source: /dev/mem",
and attempts to analyze a Linux kernel remotely just shows the kernel
timestamp and exits immediately.

- Speed up the session invocation time of "flattened" format dumpfiles
created by the makedumpfile(8) facility. When sorting the blocks of
memory by their intended ELF or compressed kdump file offsets, the
patch replaces the bubble-sort method that is currently used with an
insertion sort method.
(dslutz@verizon.com)
- Remove the non-existent "-L" option from the "ps" command's mutually-
exclusive options error message.
(vvs@parallels.com)
- Fix for the "irq", "mount", "kmem -p" and "kmem -v" commands when
they are used in an input file. If more than one of any of those
four commands are used in an input file, the output of the second
and subsequent command instances will not display their respective
command headers.
(anderson@redhat.com)
- Implemented a new "kmem -m" option that is similar to "kmem -p",
but it allows the user to specify the page struct members to be
displayed. The option takes a comma-separated list of one or
more page struct members, which will be displayed following the
page structure address. The "flags" member will always be expressed
in hexadecimal format, and the "_count" and "_mapcount" members will
always be expressed in decimal format. Otherwise, all other members
will be displayed in hexadecimal format unless the current output
radix is 10 and the member is a signed/unsigned integer. Members
that are data structures may be specified by the data structure's
member name, or expanded to specify a member of that data structure.
For example, "-m lru" refers to a list_head data structure, in which
case both the list_head.next and list_head.prev pointer values will
be displayed; if "-m lru.next" is specified, just the list_head.next
value will be displayed.
(atomlin@redhat.com, anderson@redhat.com)
- Support enhancement for the 32-bit MIPS architecture that retrieves
the per-cpu registers from the NT_PRSTATUS notes stored in the header
of compressed kdump dumpfiles.
(rabinv@axis.com)
- Fix to remove an invalid warning message on ARM64 if a crash session
is invoked with the "-d<number>" debug flag. Without the patch,
the invalid message is "WARNING: SPARSEMEM_EX: questionable section
values".
(anderson@redhat.com)
- Remove the leftover ".constructor" build file in the extensions
subdirectory when "make extensions" is complete, and update the
top-level .gitignore file to ignore post-build extensions
subdirectory files.
(anderson@redhat.com)
- Fix for a segmentation violation generated by the "help -[n|D]"
options on ARM64 compressed kdumps.
(anderson@redhat.com)
- Additional output for the "help [-D|-n]" options on ARM64. For ELF
kdump vmcores and compressed kdumps, the elf_prstatus structure in
each NT_PRSTATUS note will be translated.
(anderson@redhat.com)
- The "help -r" option has been extended to dump the ARM64 registers
stored in each per-cpu NT_PRSTATUS note in compressed kdump and
ELF kdump dumpfiles.
(anderson@redhat.com)
- Fix for the ARM64 page size determination on Linux 4.1 and later
kernels. Without the patch, the crash session fails during
initialization with the message "crash: invalid/unsupported page
size: 98304" on kernels with 64K pages. On kernels with 4K pages,
the message is "crash: invalid/unsupported page size: 6144". In
addition, the "-p <page-size>" command line override option
had no effect on ARM64; that has been fixed as well.
(anderson@redhat.com)
- Fix for the DATE display in the initial system banner and by the
"sys" command to account for the Linux 3.17 change that moved
the "timekeeper" symbol and structure into a containing tk_core
structure; the "shadow_timekeeper" timekeeper will be used as an
alternative. Without the patch, the DATE shows something within
a few hours of the Linux epoch, such as "Wed Dec 31 18:00:00 1969".
(kmcmartin@redhat.com)
- Fixes for the translation of ARM64 PTEs, as displayed by the "vm -p"
and "vtop" commands. Without the patch, if "vm -p" references a
swapped-out page on Linux 4.0 and later kernels, the SWAP location
may indicate "(unknown swap location)", and will show an invalid
OFFSET value; on Linux 3.13 and later kernels, running "vtop" on a
user virtual address incorrectly translates the PTE contents of
swapped out pages by showing a PHYSICAL address and FLAGS translation
instead of the SWAP device and OFFSET. It is possible that there may
be PTE bit translation errors on other kernel versions; the patch
addresses the changes in ARM64 PTE bit definitions made in Linux
3.11, 3.13, and 4.0 kernels.
(anderson@redhat.com)
- Enhanced the "struct.member" display capability of the "struct",
"union", "task", "list" and "tree" commands. If a specified
structure member contains an embedded structure, the output may
be restricted to just the embedded structure by expressing the
.member argument as "member.member". If a specified structure
member is an array, the output may be restricted to a single array
element by expressing the .member argument as "member[index]".
Furthermore, these embedded member specifications may extend beyond
one level deep, for example, by expressing the member argument as
"member.member.member", or "member[index].member".
(Alexandr_Terekhov@epam.com, anderson@redhat.com)
- Fix for any command that passes strings to gdb for evaluation,
where the string contains a parentheses-within-parentheses
expression along with a ">" or ">>" operator inside the outermost
set of parentheses. Without the patch, a command such as the
following fails like so:
crash> p ((1+1) >> 1)
p: gdb request failed: p ((1+1)
crash>
(anderson@redhat.com)
- Fix for the handling of ARM64 kernel module per-cpu symbols. Without
the patch, if the debuginfo data of an ARM64 kernel module that
contains a per-cpu section is loaded by "mod -s <module>" or
"mod -S", commands such as "bt" or "sym" may incorrectly translate
the module's virtual addresses to symbol names.

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.

- 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.

- 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:

- 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.

- 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.

- 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".

- 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.

- 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

not available, just the page.flags value is printed in hexadecimal,
as has been done since Linux 2.4.9.

- 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.

- Re-execution of 150764 by tabraham@suse.com to re-align patch
content, re-number patches for latest spec contents and to
remove some incidental content (e.g. whitespace insertion and
leftover comments of new lines). 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".

makedumpfile version 1.4.4 or later.
* Fri Jun 01 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 2012 ptesarik@suse.cz
- delete crash-foreach-match-running.patch: upstream
* Mon May 14 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 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 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 07 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 '\'

* Mon Jan 03 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 2010 dmair@novell.com

values into dynamically calculated values.
o Call FREEBUF() on a GETBUF()-generated buffer ub the
do_radix_tree() utility function.
o x86_64: Store the .debug_frame section offset and size from

o New option "ps -G" to restrict the process status output to the thread
group leader of a thread group
o Several fixes for the "repeat" command when used in conjunction
with an input file. Without the patch:
- Depending upon the command executed from the input file, a SIGINT
would kill the command currently being executed from the input file,
but the "repeat" command would then restart it.
- If a command in the input file redirected its output to a pipe, the
repeat operation could stop prematurely after executing that particular
command.
- If a command in the input file redirected its output to a pipe, the
zombies of the command being piped to would not be cleaned up until the
repeat command was stopped.
- If the last command in the input file redirected its output to a pipe,
all subsequent executions of the input file would only display the
output of that last command.

x86_64 kernel versions
o Multiple fixes for the "bt" command on x86_64:
