Verification for Bionic Ran the xfstests (https://git.kernel.org/pub/scm/fs/xfs/xfstests- dev.git) on the current 5.4.0-109-generic #123~18.04.1-Ubuntu kernel and the -proposed kernel 5.4.0-110-generic #124~18.04.1-Ubuntu in a VM to exercise the XFS filesystem thoroughly. Detailed log files of the tests are attached.
The tests completed successfully on both kernels, with the -110 kernel showing no regressions relative to the -109 kernel. ** Attachment added: "110-xfs-bionic.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1966803/+attachment/5584116/+files/110-xfs-bionic.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1966803 Title: xfs: Fix deadlock between AGI and AGF when target_ip exists in xfs_rename() Status in linux package in Ubuntu: Invalid Status in linux source package in Focal: Fix Committed Bug description: SRU Justification: [Impact] * The xfs filesystem suffers from a deadlock issue in kernels < 5.5. This hangs IO to/from the affected filesystem. Sample backtraces added as a comment. [Fix] * 93597ae8dac0149b5c00b787cba6bf7ba213e666 93597ae8dac0 "xfs: Fix deadlock between AGI and AGF when target_ip exists in xfs_rename()" * This is from the upstream 5.5 kernel. [Test Plan] * Set up an Ubuntu Bionic/Focal installation using kernel 5.4. * Create and mount an XFS filesystem on a block device. * Exercise the filesystem to verify that IO does not hang. [Where problems could occur] * This patch could cause locking issues on XFS filesystems, requiring a system restart to correct. [Other Info] * Bug is difficult to reproduce, a test kernel on affected systems with the above patch prevented the issue. * Backports to earlier (4.15 and earlier) kernels have been omitted as the upstream patch does not apply cleanly and the issue has not been reproduced on them.
