Title:
Bump crash version on Bionic and Eoan to match Focal
Status in crash package in Ubuntu:
Confirmed
Status in crash source package in Bionic:
In Progress
Status in crash source package in Eoan:
In Progress
Bug description:
[Impact]
* The crash tool aims to allow investigating kernel core dumps collected
through the kexec mechanism; as such, this tool is tightly coupled with kernel
version, needing awareness for example about kernel structs layout and other
kernel "API" details.
* Currently the crash tool is outdated in Bionic, not allowing users
to debug kernel core dumps collected with the latest HWE kernel
(version 5.3). Also, many bugs and improvements are added to crash as
newer kernels are released.
* This LP's goal is to bump the version of crash tool in both Bionic
and Eoan in order to match Focal version (7.2.8). With that we can
address the Bionic issue when opening kernel 5.3 dumps and gather more
fixes with the updated package.
[Test Case]
* The test performed is basically collect dumps with kdump-tools and open in
crash. In this particular case, the tests were with kernels 4.15.0-88 and
5.3.0-26 (in Bionic) and kernel 5.3.0-23 (in Eoan) using the crash tool built
with the hereby attached source.
[Regression Potential]
* Crash tool aims to have full retro-compatibility with kernel, so the
likelihood for regressions are low. If regressions are found, it's likely the
same regression applies to all crash/kernel pair versions, so by having the
package synced between releases we increase the exposure to gather more bug
reports and fix things in a more straightforward fashion.
NOTICE: This bump was agreed with Ubuntu kdump-tools/crash maintainer,
Thadeu Cascardo.
