Hello, We are researchers from Columbia University, New York. As part of our current research we have run into some issues using xfs filesystem. For example, we encountered a case where the setuid bit of a modified executable was not removed as desired. We have attached three cases, one involving the setuid bit in directory 1, and a data corruption issue in directory 2. In directory 3 is a semantic discrepancy we discovered between xfs and other popular filesystems (ext4/btrfs) regarding the setgid bit. In each directory, you will find a Readme describing the issue and pointing to the code that may lead to the issue. For your convenience, we also included test programs (min.cpp) and instructions in Readme to help reproduce the issues. We tried to report them on bugzilla@xxxxxxxxxxx but the website seems to be down. We would appreciate very much if you could confirm the three cases at your conveniences. Thanks, Amy
