Description

Hello, following the repo sync earlier today (after the first, before the second one) I am no longer able to run clr-boot-manager update

root@solus # clr-boot-manager update
Segmentation fault (core dumped)

apparently the libblkid.so file it refers to is a part of the util-linux package, which was also updated in the repo sync

* util-linux is upgraded from 2.28-17-1-x86_64 to 2.30.2-18-1-x86_64.

A sneaky workaround which I wouldn't rely on forever, but it works for now:

Download the old 2.28 version of util-linux from the shannon repo: https://packages.solus-project.com/shannon/u/util-linux/util-linux-2.28-17-1-x86_64.eopkg
Open it in archive manager, browse to install.tar.xz->usr->lib64
Extract libblkid.so.1.1.0 somewhere
Backup the current library somewhere safe: sudo mv /usr/lib64/libblkid.so.1.1.0 /usr/lib64/libblkidso.1.1.0.disabled
Copy in the library you just extracted: sudo cp /path/to/extracted/libblkid.so.1.1.0 /usr/lib64/
Update your boot menu: sudo clr-boot-manager update
Restore the library from backup: sudo mv /usr/lib64/libblkid.so.1.1.0.disabled /usr/lib64/libblkid.so.1.1.0

This is for a one-time cbm run, I expect the devs will fix the packages soon.
If something goes awfully wrong, run sudo eopkg install --reinstall util-linux to get everything back where it should be.

Stupid question: did you try to execute clr-boot-manager a 2nd time before you replaced the library ?

Or better yet

sudo CBM_DEBUG=1 clr-boot-manager update

I tried it about five times before touching util-linux, including once on the linux-lts kernel, with a segfault every time. I only looked at the journalctl for two of them, but both were libblkid.so related errors.

My first util-linux attempt was to completely overwrite the package with the old version, which worked too, but clr-boot-manager complained it couldn't delete some module and kernel files. The second attempt used the steps listed above, and worked without complaining.

My clr-boot-manager still segfaults even on the latest kernel, with the same error 4 in libblkid.so.1.1.0 message.

the output with CBM_DEBUG=1:

Desktop installation is borked, need to go out so I can't fix it right now. However, I recommend not rebooting / or not installing kernel updates right now

I need usable information to help me here. Please install util-linux-dbginfo glibc-dbginfo clr-boot-manager-dbginfo and run it via gdb so I have a stack trace,
as I'm unable to reproduce.

What's the commonality between your systems? Are you all on BIOS, UEFI? Encrypted, nay..?

oft added a comment.Oct 15 2017, 7:15 PM

I am on UEFI + Full Disk Encryption. My laptop is Thinkpad 13 (first generation, Skylake).

It would appear you're all hitting the same segfault in blkid_partlist_numof_partitions though..

I'm my case I have Bios and full disk encryption, made by Solus' installer

OK so thats 2 for FDE - everyone else FDE?

Icepickle added a subscriber: Icepickle.EditedOct 15 2017, 8:01 PM

I have experienced this problem as well several times today, when I did the installation using the LVM partitioning system, without encryption

Eventually, I decided to reinstall a fifth time today, but disabled the LVM creation, and now my kernel succesfully updated, so probably it looks like a problem with LVM created partitions ;)

In neither case, I had encryption enabled, so I cannot verify that

OK that's also curious - FDE relies on LVM btw.

Are you all on current kernel series or lts ?

@ikey I experienced both with the 4.9.22-17.lts (an older installation source I had) as with the 4.12.7-11.current using the latest ISO I could download

(btw I checked LVM but not FDE when it was not working, now it is working without any of those options checked during the installation)

No FDE for me, UEFI, running current

I'm using just current (did clean install when Solus 3 was released and I chose in the installer to use all disk)

Before 4.13.6 I had installed any kernel update without any problem (same clean install)

I'm on FDE, but I don't think I'm using UEFI. My kernel is linux-current, but the segfault also occured on -lts yesterday.

Downgrading util-linux in the ISO makes the installer work again, but it looks like CBM somehow still died there... Unhelpful.

Yeah no FDE here, just LVM whole disk.

Brand new install from Solus 3 iso, once I upgrade I get the same thing. UEFI + Full Disk Encryption.

Steps taken (after each step a full reinstall was performed, then upgraded):

  1. Tried installs in both UEFI and Legacy BIOS modes
  2. Tried installs with LUKS / LVM crypt and without
  3. Tried zeroing partition tables via
dd if=/dev/zero of=/dev/sda bs=1M count=500
  1. Cleared out all previous UEFI entries via
sudo rm -f '/sys/firmware/efi/efivars/'* || sync

The common thread here is LVM - tryna figure out whats going on.

Can repro this in a VM from Solus 3 Budgie, kernel isn't getting promoted on LVM

ikey changed the task status from Open to In Progress.Oct 18 2017, 1:32 PM
ikey claimed this task.

Very interesting, even get-timeout causes a segfault.

OK so the problem is cbm_blkid_probe_get_partitions is actually returning NULL..

Gotcha ya slippery bastard


Merged upstream, awaiting 1.5.5 release (but of course github broke too)

Silly question, but how does one effect the new changes put up on github?

Due to arrive on Fridays sync, which will also be accompanied with the latest kernel builds to automatically restore kernel
consistency.

If you want/need this right now:

sudo eopkg it --ignore-dependency https://packages.solus-project.com/unstable/c/clr-boot-manager/clr-boot-manager-1.5.5-17-1-x86_64.eopkg
sudo clr-boot-manager update

Awesome news, thanks @ikey!

Thanks, this worked perfectly for me.

Apologies for the issue, honestly. We're gonna need to build some test harnesses around this stuff..
