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Note change of no longer valid old project whitepaper URL to current valid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.
(bsc#1179536)
* 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.
(bsc#1162297)
* Fri Sep 04 2020 ptesarik@suse.com

* Sat Apr 18 2020 msuchanek@suse.com
- Make Factory ppc64 crash usable on both SLE 15 SP1 and releases before
SLE15 SP1 (bsc#1148197). This is only a workaround that requires to build
crash for each codestream separately.
* Fri Apr 17 2020 msuchanek@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

* Wed Aug 08 2018 msuchanek@suse.com
- Added:
crash-Fix-and-an-update-for-the-ipcs-command.patch
The update is required for Linux 4.11 and greater kernels, which
reimplemented the IDR facility to use radix trees in kernel commit
0a835c4f090af2c76fc2932c539c3b32fd21fbbb, titled "Reimplement IDR and IDA

7.2.1 source (bsc#1103371).
Removed:
crash-ppc64-book3s-update-hash-page-table-geometry.patch
crash-x86_64_kvtop-usable-symtab_init.patch
crash-ppc64-ensure-chosen-stack-symbol-relates-to-an-actual-backtrace.patch

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
- Upgrade of source tarball to 7.1.8 from upstream and refresh of
patches to align with the version. For a detailed changelog of
the source tarball see:

+ 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().

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.
(dslutz@verizon.com, anderson@redhat.com)
- 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.
