- 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.

- 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.
- Drop crash-s390-autodetect-kaslr.patch which has been merged in 7.2.7.
Merge missing patches from SLE15 SP2:
crash-stop_read_error_when_intent_is_retry.patch
crash-SLE15-SP1-With-Linux-4.19-rc1-up-MAX_PHYSMEM_BITS-to-128TB.patch
crash-SLE15-SP1-Fix-for-PPC64-kernel-virtual-address-translation-in.patch
And SLE 15 SP2 bug references and changelog entries:
- 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:
- Added patch for commit 326e1b8f83a4318b09033ef754f40c785aed5e68
Upgraded the source tarball to version 7.2.6 to bring better
support of version 5 kernels such as 5.3 in SLE-15-SP2
(bsc#114706)
Dropped the following patches obsoleted by the version upgrade:
crash-Fix-and-an-update-for-the-ipcs-command.patch
crash-update-recognition-of-x86_64-CPU_ENTRY_AREA.patch
Re-aligned the following patches with the new version source:
crash-allow-use-of-sadump-captured-KASLR-kernel.patch
crash-debuginfo-compressed.patch
crash-make-emacs-default.diff
crash-sles9-time.patch
Modified the following patches to integrate with version upgrade:
crash-compressed-booted-kernel.patch
crash-SLE15-SP1-With-Linux-4.19-rc1-up-MAX_PHYSMEM_BITS-to-128TB.patch
crash-SLE15-SP1-Fix-for-PPC64-kernel-virtual-address-translation-in.patch
- Update for XEN dom0 changes in v4.11 that cause coredumps made
of a domU using virch on the dom0 to fail to load in the dom0
version of crash reporting "crash: invalid kernel virtual address:
<address> type:fill_pcpu_struct", followed by "WARNING: cannot
fill pcpu_struct" and "crash: cannot read cpu_info"
(bsc#1124690 and bsc#1122594)
Added:
- Update the recognition of x86_64 CPU_ENTRY_AREA (bsc#1104743, bsc#1090127)
Added:
crash-update-recognition-of-x86_64-CPU_ENTRY_AREA.patch
- Fix SLE15 SP1 Incorrect vmcore generated (bsc#1119791).
Added:
crash-SLE15-SP1-With-Linux-4.19-rc1-up-MAX_PHYSMEM_BITS-to-128TB.patch
crash-SLE15-SP1-Fix-for-PPC64-kernel-virtual-address-translation-in.patch
This is not compatible with SLE15 and SLE12 SP4.
- 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
using the radix tree". Without the patch, if any IPCS entry exists, the
command would fail with the message "ipcs: invalid structure member offset:
idr_top" (bsc#1092101)

- Includes alignment of Factory/SLE-12-SP3 tracker content
- 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).
- Exclude openSUSE from RT KMP build (bsc#1013843)
- Fix analyzing fadump dumps on PPC64 (bsc#1022962).
- Enabled RT KMP build (bsc#1005578)
- crash-linux-4.6-printk-flags.patch: Fix warning "failed to read
pageflag_names entry" on Linux 4.6 (bsc#978601).
- eppic-support-arm64.patch: Support for ARM64 (FATE#320844).
- Disable RT KMP build (bsc#962719)
- Enable RT KMP build (bsc#948840)
- Update to 7.1.3 (bsc#946458)
o Introduction of "dis -f <address>" which disassembles from the
address to the end of the function
o Introduction of "dis -s <address>" which displays the filename
and line number associated with the specified text location,
followed by a source code listing if available.
o Addition of a new "--src <directory>" command line option for
use by the "dis -s" option if the kernel source is not located
in the standard location.
o Do not search for a panic task in s390x dumpfiles that are
marked as a "live dump"
