Package: util-linux Version: 2.42.3-1 Severity: normal X-Debbugs-Cc: [email protected]
Hello there, Something™ breaks in util-linux >2.42, likely in `libmount1`. This was caught by the `squashfs-mount` autopkgtest in Ubuntu, because we do run them with `isolation-machine` as opposed to Debian: * https://ci.debian.net/packages/s/squashfs-mount/unstable/amd64/ * https://autopkgtest.ubuntu.com/packages/s/squashfs-mount/stonking/amd64 I didn't dig into the `util-linux` codebase, but here is a simple reproducer script: ```bash #!/usr/bin/bash WORK_DIR=$(mktemp -d) cd "$WORK_DIR" mkdir -p folder echo "Hello there" > folder/hello.txt mksquashfs folder image.sqfs -quiet -noappend mkdir -p mnt squashfs-mount image.sqfs:mnt -- cat mnt/hello.txt cd - rm "$WORK_DIR" -rf ``` Run that in an Ubuntu Stonking VM against 2.41.3-3ubuntu2: ``` skia@kiffex:~ ❯ lxc launch -e ubuntu-daily:26.10 ubuntu-stonking --vm Launching ubuntu-stonking skia@kiffex:~ ❯ lxc shell ubuntu-stonking root@ubuntu-stonking:~# apt update -qq 178 packages can be upgraded. Run 'apt list --upgradable' to see them. root@ubuntu-stonking:~# apt install -qq squashfs-mount Installing: squashfs-mount [...] root@ubuntu-stonking:~# su ubuntu ubuntu@ubuntu-stonking:~$ dpkg-query -W libmount1 libmount1:amd64 2.41.3-3ubuntu2 ubuntu@ubuntu-stonking:~$ ./reproducer.sh [==================================================================================================================================================|] 1/1 100% Hello there /home/ubuntu ubuntu@ubuntu-stonking:~$ ``` And the same against 2.42.3-1 on Debian unstable: ``` skia@kiffex:~ ❯ lxc launch -e images:debian/sid debian-sid --vm Launching debian-sid skia@kiffex:~ ❯ lxc shell debian-sid root@debian-sid:~# apt update && apt install squashfs-tools squashfs-mount [...] root@debian-sid:~# useradd debian root@debian-sid:~# su debian $ bash debian@debian-sid:/root$ cd /tmp debian@debian-sid:/tmp$ vim reproducer.sh debian@debian-sid:/tmp$ dpkg-query -W libmount1 libmount1:amd64 2.42.3-1 debian@debian-sid:/tmp$ ./reproducer.sh [==================================================================================================================================================|] 1/1 100% /tmp/tmp.fgOxcel9XK/mnt: can't find in /etc/fstab /tmp ``` I left severity "normal" because technically, the Debian QA didn't raise an eyebrow on the issue, so nothing is broken per say, but I would consider raising the priority considering this is indeed breaking other packages. Let me know if you need anything else to help reproduce or debug. Cheers Skia
