Title:
update makedumpfile tool version to v1.6.3
Status in The Ubuntu-power-systems project:
In Progress
Status in makedumpfile package in Ubuntu:
Fix Released
Bug description:
[Impact]
New upstream kernel versions, as those in linux-hwe package, require a newer
makedumpfile to be supported. Otherwise, all copies fallback to copying the
entire memory.
[Test case]
kdump-tools has been installed, system rebooted, then crash trigerred and
verified that a small dump file was present on /var/crash/. Tested on amd64 and
ppc64le.
[Regression potential]
Many other bug fixes have been included in the latest version of the package.
The changes are supposed to fix these bugs, and have been tested as well.
However, as the total of changes is not trivial, there is impact of regression
that has been minimized by the tests done. Regression potential of not
supporting older kernels has been tested with the kernels shipped on xenial and
artful as well.

---Problem Description---
update makedumpfile to latest version v1.6.3 that officially supports
up to kernel version 4.14.8. Since makedumpfile is inherently backward
compatible,
this would not break existing functionality..
Contact Information = [email protected]
---uname output---
na
Machine Type = na
---Debugger---
A debugger is not configured
---Steps to Reproduce---
makedumpfile reports ""The kernel version is not supported" while generating
vmcore
Also, there is a possibility of bogus address translations in makedumpfile
tool with
missing upstream patches. Can't be so sure without an exhaustive testing.
Instead,
it would be a good idea to go with the version which officially supports the
kernel
version in question.
Userspace tool common name: makedumpfile
The userspace tool has the following bit modes: 64-bit
Userspace rpm: makedumpfile
Userspace tool obtained from project website: na
*Additional Instructions for [email protected]:
-Attach ltrace and strace of userspace application.

With kernel version updated to 4.13.0, please update makedumpfile tool
version to 1.6.3 which officially supports up to kernel version 4.14.8 [1].
Thanks
Hari
