This patch updates kexec-tools from 2.0.15 to 2.0.21 (and its supporting software package makedumpfile from 1.6.2 to 1.6.9) for compatibility with the newer v5.10 kernel. This commit clones the kexec-tools package's supporting files from commit 26a7a543427eac59ed39728466f3d95d320f735a in the CentOS RPM packaging git repository. Links for reference: -26a7a54342-26a7a54342Please note that this patch causes the build system to pull in and extract an SRPM file to acquire: kdump-anaconda-addon-003-29-g4c517c5.tar.gz This is done for security, because the only public reference to commit 4c517c5 is on a Red Hat developer's personal Github account: https://github.com/ryncsn/kdump-anaconda-addon/commits/rhel-7 kexec-tools package's supporting files cloned by this commit trigger a large number of shell script linting errors. Given that the shell scripts in question are inherited from upstream (i.e., CentOS 7), the "files" directory of this package is excluded from automated linting via the changes in tox.ini. Verification: A kexec-tools RPM package built with this commit was installed onto an existing StarlingX system. A vmcore file was succesfully collected from a kernel crash triggered with /proc/sysrq-trigger. A recent version of the crash utility was found to succesfully parse the collected vmcore file. Credits: Thanks to Jiping Ma for helping with cleaning up and publishing an earlier version of this patch.
