** Description changed: Trying to checkpoint a container (docker/podman) on 18.04 fails starting with linux-image-5.0.0-35-generic. We (CRIU upstream) see this in Travis starting a few weeks ago. Manually testing it locally shows that linux- image-5.0.0-32-generic still works and linux-image-5.0.0-35-generic does not longer work. It seems to be overlayfs related, at least that is what we believe. The CRIU error message we see is: (00.170944) Error (criu/files-reg.c:1277): Can't lookup mount=410 for fd=-3 path=/bin/busybox (00.170987) Error (criu/cr-dump.c:1246): Collect mappings (pid: 1637) failed with -1 We have not seen this only in Travis, but also multiple CRIU users reported that bug already. Currently we have to tell them to downgrade the kernel. I also able to reproduce it with linux-image-5.3.0-24-generic. Staying on the 4.18.0 kernel series does not show this error. 4.18.0-25-generic works without problems. See also https://github.com/checkpoint-restore/criu/issues/860 One of the possible explanations from our side include: "Looks like we have the same as for st_dev now with mnt_id, that is bad, because we can't find on which mount to open the file if kernel hides these information from us." Running on the upstream 5.5.0-rc1 kernel does not show this error. + --- + ProblemType: Bug + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 Jan 7 18:52 seq + crw-rw---- 1 root audio 116, 33 Jan 7 18:52 timer + AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' + ApportVersion: 2.20.11-0ubuntu8.2 + Architecture: amd64 + ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + CRDA: N/A + DistroRelease: Ubuntu 19.10 + IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' + Lsusb: Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + MachineType: DigitalOcean Droplet + Package: linux (not installed) + PciMultimedia: + + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.3.0-26-generic root=PARTUUID=5b57f3f9-086a-4a7d-ae78-efdee8842586 ro console=tty1 console=ttyS0 + ProcVersionSignature: Ubuntu 5.3.0-26.28-generic 5.3.13 + RelatedPackageVersions: + linux-restricted-modules-5.3.0-26-generic N/A + linux-backports-modules-5.3.0-26-generic N/A + linux-firmware N/A + RfKill: Error: [Errno 2] No such file or directory: 'rfkill': 'rfkill' + Tags: eoan uec-images + Uname: Linux 5.3.0-26-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: + + _MarkForUpload: True + dmi.bios.date: 12/12/2017 + dmi.bios.vendor: DigitalOcean + dmi.bios.version: 20171212 + dmi.chassis.type: 1 + dmi.chassis.vendor: Bochs + dmi.modalias: dmi:bvnDigitalOcean:bvr20171212:bd12/12/2017:svnDigitalOcean:pnDroplet:pvr20171212:cvnBochs:ct1:cvr: + dmi.product.family: DigitalOcean_Droplet + dmi.product.name: Droplet + dmi.product.version: 20171212 + dmi.sys.vendor: DigitalOcean ** Attachment added: "CurrentDmesg.txt" https://bugs.launchpad.net/bugs/1857257/+attachment/5318308/+files/CurrentDmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857257 Title: linux-image-5.0.0-35-generic breaks checkpointing of container To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1857257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
