Kexec has stoppped working

jiivee · May 14, 2022, 11:13am

After doing distribution upgrade to machines yesterday (2022-05-13), they no longer boot with kexec, but rather do a full reboot. This is an issue, because during full reboot process root filesystem encryption password must be entered interactively. By using kexec I have avoided that for mainly headless machines.

Below first comes some environment related info and then log snippets.

Description    :  
    Kexec is a user space utility for loading another kernel and asking the 
    currently running kernel to do something with it. A currently running 
    kernel may be asked to start the loaded kernel on reboot, or to start 
    the loaded kernel after it panics.

From logs I found normal kexec-load.service’s log line. Thus configuration itself seems to be still working.

Can following log lines be related to kexec no longer working?

You need to provide more details about what you are doing so that someone could verify/reproduce it. Explain step by step how you perform kexec (because e.g. “systemctl kexec” simply refuses to do anything in my case).

jiivee · May 14, 2022, 11:50am

Kexec replaces normal reboot. Symbolic link in /etc/systemd/system/reboot.target does (has done) that. Thus normal

shutdown -r +0

should do reboot using kexec rather than going through grub and it asking password for root/boot disk decryption.

arvidjaar · May 14, 2022, 9:46pm

Well, pure kexec (without messing with systemd) works for me on TW with kernel 5.17.5 in VM with legacy BIOS and does not work (goes via full reboot) on VM with UEFI. kexec works on Leap 15.2 using UEFI and Leap 15.3 using legacy BIOS. So it looks like regression.

Does it work using older kernel? If yes, you should definitely open bug report.

jiivee · May 15, 2022, 11:18am

Kernels 5.17.4-1-default and 5.17.5-1-default behave similarly.

Below is dracut version information.

After installing above mentioned packages, I rebooted machine. It did a full reboot. I gave it a second reboot try. Still a full reboot. Below is log snippets from that second reboot. Kernel is 5.17.5-1-default. At least dracut gives different errors now.

Quoting your original post:

This implies that before update it worked. It is up to you to find out what changed. If you revert to the snapshot before upgrade, does kexec work again? What TUmbleweed version did you have before this upgrade?

jiivee · May 15, 2022, 8:19pm

Sure it worked. Previous TW version seems to have been 20220428.

How to find out what packages were updated during latest distribution upgrade?

arvidjaar · May 16, 2022, 7:19am

I am not sure if I did not misinterpret what I saw. I cannot reproduce it now. Both VM with TW do full reboot.

Well, I tried to install the latest kernel-stable and kexec-tools in Leap 15.3 and kexec still works as expected. At this point I have to ask once more - does kexec work when you revert to snapshot before update? I also believed that it was working …

How to find out what packages were updated during latest distribution upgrade?

There is /var/log/zypp/history or you can simply compare full content of RPM datbase between previous snapshot and current system (do something like “rpm -qa --dbpath /.snapshots/your-snapshot/usr/lib/sysimage/rpm | sort” and “rpm -qa | sort” and compare two lists). snapper can also show diffs between files in snapshot.

jiivee · May 16, 2022, 6:23pm

Yes, booting from previous snapshot (kernel-5.17.4-1-default) and rebooting from there. Kexec works then, although similar errors are logged:

Doing normal reboot after this yielded again to full reboot.

Thanks for hinting how to find changes.

Well, sdiff output from those rpm databases is 2890 rows long. It is much easier to tell what has not changed rather than what has changed. Few changes are listed below.

I noticed that zypper info reported dracut version being outdated, thus I did distribution upgrade. Kernel is now newer, but kexec did not magically get fixed.

Thanks for link to bug.

I grabbed kexec-tools 2.0.22-2.1 from https://download.opensuse.org/history/20220509/tumbleweed/repo/oss/x86_64/ as https://download.opensuse.org/history/20220509/tumbleweed/repo/oss/x86_64/kexec-tools-2.0.22-2.1.x86_64.rpm and installed it. After this reboot reboots using kexec again.

For the time being, I tried to protect installed kexec-tools version from being updated:

zypper addlock kexec-tools
zypper addlock -t patch kexec-tools

I’ll keep watching kexec bug being fixed.

kexec-tools-2.0.24-1.1.x86_64.rpm in Tumbleweed fixed issues with kexec boot failure.
