Description Josh Poimboeuf 2014-12-03 22:20:20 UTC

Description of problem:

Running "kpatch install" fails to load the patch module after a reboot.  The syslog shows the following errors:

Dec 03 16:47:49 hp-dl160gen8-02.khw.lab.eng.bos.redhat.com dracut-pre-udev[404]: /usr/sbin/kpatch: line 125: readelf: command not found
Dec 03 16:47:49 hp-dl160gen8-02.khw.lab.eng.bos.redhat.com dracut-pre-udev[404]: /usr/sbin/kpatch: line 125: awk: command not found
Dec 03 16:47:49 hp-dl160gen8-02.khw.lab.eng.bos.redhat.com dracut-pre-udev[404]: cat: /sys/kernel/kpatch/patches//enabled: No such file or directory
Dec 03 16:47:49 hp-dl160gen8-02.khw.lab.eng.bos.redhat.com dracut-pre-udev[404]: /usr/sbin/kpatch: line 125: readelf: command not found
Dec 03 16:47:49 hp-dl160gen8-02.khw.lab.eng.bos.redhat.com dracut-pre-udev[404]: /usr/sbin/kpatch: line 125: awk: command not found
Dec 03 16:47:49 hp-dl160gen8-02.khw.lab.eng.bos.redhat.com dracut-pre-udev[404]: kpatch: error: cannot re-enable patch module , cannot verify checksum match

This is a regression caused by bug 1148852.  Some new dependencies (readelf and awk) were added to the kpatch script, but the kpatch dracut module code wasn't updated to specify them.

Version-Release number of selected component (if applicable):
kpatch-0.1.10-3.el7.noarch

How reproducible:
kpatch install and reboot

Steps to Reproduce:
1. yum install http://download.devel.redhat.com/brewroot/work/tasks/8247/8328247/kpatch-patch-7.1-0.210.el7.x86_64.rpm
2. yum install http://download.eng.bos.redhat.com/redhat/brewroot/packages/kernel/3.10.0/210.el7/x86_64/kernel-3.10.0-210.el7.x86_64.rpm
3. reboot
4. kpatch list

Actual results:
The installed patch module is not loaded after a reboot.

Expected results:
The installed patch module is loaded after a reboot.

Additional info:
Fixed upstream with https://github.com/dynup/kpatch/pull/473
