Hello Dominic, or anyone else affected, Accepted util-linux into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/util- linux/2.34-0.1ubuntu9.4 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: util-linux (Ubuntu Focal) Status: In Progress => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/2015355 Title: Please backport patches for false atari partition detection to Ubuntu 20.04 Status in util-linux package in Ubuntu: Fix Released Status in util-linux source package in Focal: Fix Committed Bug description: [Impact] The partition detection logic in libblkid1 can falsely report the presence of an atari partition. One place where this has a practical impact is in kubernetes where mount-utils will refuse to format the device (https://github.com/kubernetes/mount- utils/blob/732a08ae47571516020ef99c303c70c1fa5b3e6c/mount_linux.go#L437-L441). [Test Plan] * Create a new qcow2 disk image: $ qemu-img create -f qcow2 test.img 20G * Boot a focal ISO with QEMU/KVM as if installing to test.img: $ qemu-system-x86_64 -enable-kvm -m 4096 -name test -drive file=test.img,format=qcow2 -net nic,model=virtio -net user,hostfwd=tcp::1022-:22 -vga virtio -cdrom ubuntu-20.04.6-desktop- amd64.iso * Using the live environment, format the empty disk. These particular commands were given as a reproducer on the upstream bug report (https://github.com/util-linux/util-linux/issues/1116). $ parted -s /dev/sda -- mklabel msdos $ parted -s /dev/sda -- mkpart primary 0% 10% mkpart primary 10% 30% * Run wipefs on /dev/sda to list partitions. On an affected machine, an atari partition will be listed. On a fixed machine, the incorrect atari listing will be gone. $ wipefs /dev/sda DEVICE OFFSET TYPE UUID LABEL sda 0x1fe dos sda 0x1d2 atari [Where problems could occur] These patches specifically address the atari prober logic in libblkid. Therefore, if we saw regressions it would be related to detecting atari partitions with libblkid. This would potentially impact tools such as wipefs and blkid, or any other tool that uses libblkid1 for this purpose. [Original Description] There are three patches in util-linux upstream that were released in util-linux 2.37 and prevent false detection of the atari partition table with blkid and wipefs. We see this mostly on LUKS devices initialised via luksFormat reporting there is an atari partition table on the device when it is empty. This causes issues in various places, but one key example for us is in kubernetes where mount-utils will refuse to format the device (https://github.com/kubernetes/mount- utils/blob/732a08ae47571516020ef99c303c70c1fa5b3e6c/mount_linux.go#L437-L441) RedHat backported these fixes to RHEL 8 under https://bugzilla.redhat.com/show_bug.cgi?id=2060030 and it would be helpful if Ubuntu also backported them to Ubuntu 20.04 which is still running util-linux 2.34 The request is to backport patches based on the https://github.com/util-linux/util-linux/issues/1159 upstream report.
