Product: File System Version: 2.5 Kernel Version: 5.17 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: XFS Assignee: filesystem_xfs@xxxxxxxxxxxxxxxxxxxxxx Reporter: yanming@xxxxxxxxxx Regression: No Created attachment 300858 --> https://bugzilla.kernel.org/attachment.cgi?id=300858&action=edit case.c, contains file operations to reproduce the bug I have encountered a XFS bug in the kernel v5.17. I have uploaded the system call sequence as case.c, and a modified image can be found on google net disk (https://drive.google.com/file/d/1EzzOv74RIXjRdjMD1emDYN3241goinlp/view?usp=sharing). You can reproduce this bug by running the following commands: gcc -o case case.c losetup /dev/loop0 case.img mount -o "allocsize=4096,attr2,discard,nogrpid,filestreams,noikeep,noalign,wsync" /dev/loop0 /mnt/test/ ./case The kernel crash log is shown below: 4,918,9602591861,-;XFS (loop0): correcting sb_features alignment problem 0,919,9602592537,-;XFS: Assertion failed: mp->m_sb.sb_versionnum & XFS_SB_VERSION_DIRV2BIT, file: fs/xfs/libxfs/xfs_dir2.c, line: 99 4,920,9602592552,-;------------[ cut here ]------------ 2,921,9602592553,-;kernel BUG at fs/xfs/xfs_message.c:110! 4,922,9602592559,-;invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI 4,923,9602592564,-;CPU: 7 PID: 2786 Comm: mount Not tainted 5.17.0 #7 4,924,9602592567,-;Hardware name: Dell Inc.
