Description Martin Pitt 2024-11-26 16:15:48 UTC

Today's rawhide updates broke checkpoint/restore in podman/criu. I bisected the package updates, and the trigger is the kernel.

works: kernel-core-6.13.0-0.rc0.20241119git158f238aa69d.2.fc42.x86_64
fails: kernel-core-6.13.0-0.rc0.20241125git9f16d5e6f220.8.fc42.x86_64


Reproducible: Always

Steps to Reproduce:
podman run --name=test1 -d quay.io/libpod/busybox sleep 1000
podman container checkpoint test1

Actual Results:  
2024-11-26T16:11:08.428787Z: CRIU checkpointing failed -52.  Please check CRIU logfile /var/lib/containers/storage/overlay-containers/2a3d740ede2eed92a3f963902dcb12bdd4e476ee2f3f73ffc86dfee71a5f9fbe/userdata/dump.log

Expected Results:  
checkpointing works

Please reassign to the kernel if that's an actual regression, and not just criu needing an update to kernel changes.

Comment 1 Martin Pitt 2024-11-26 16:18:13 UTC

Lokesh, FYI. That's the regression discussed in https://github.com/containers/podman/pull/24682#issuecomment-2500237227 ff., and it affects podman.

Comment 2 Radostin Stoyanov 2024-11-26 17:51:51 UTC

We opened the following GitHub issue to track this problem upstream: https://github.com/checkpoint-restore/criu/issues/2532

Comment 3 Radostin Stoyanov 2024-12-08 09:31:34 UTC

This error has been fixed upstream in CRIU with the following pull request: https://github.com/checkpoint-restore/criu/pull/2539.
We have updated the CRIU package in Fedora Rawhide with this patch.

Comment 4 Paul Holzinger 2024-12-11 17:28:20 UTC

@rstoyano Can you have a look at the failures in https://bodhi.fedoraproject.org/updates/FEDORA-2024-317bb280cd and fix or waive them so this update can get into the stable repo? Thanks.

Comment 5 Radostin Stoyanov 2024-12-11 17:38:57 UTC

Thank you for pointing this out! I waived this test to pass CI.

Comment 6 Martin Pitt 2024-12-23 07:22:36 UTC

Confirmed fixed in current rawhide. Thanks!
