Package: xfsprogs Version: 6.17.0-2 Severity: normal There is a XFS file system created with default options plus -n parent=1 in order to create parent pointers. The file system contains the two files 0 and O.
Running xfs_scrub -n -k -v on the file system results in an error: kernel: xfs_scrub[47385]: segfault at 0 ip 00007fb4730bfa23 sp 00007fb46f7fc198 error 4 in libc.so.6[b5a23,7fb473032000+168000] likely on CPU 3 (core 3, socket 0) kernel: Code: ff 66 0f 1f 44 00 00 66 0f 6e ce 89 f8 25 ff 0f 00 00 66 0f 60 c9 3d c0 0f 00 00 66 0f 61 c9 66 0f 70 c9 00 0f 8f 4d 01 00 00 <f3> 0f 6f 07 66 0f ef db 66 0f 6f e0 66 0f 74 c1 66 0f 74 e3 66 0f This also happens if the file system contains only a file - e.g., ''$'\033' - with control characters. The exit code is in both cases 139. The same tests on a file system differing only in the absence of parent pointers result in the following info respectively warning: Info: inode 128 (0/128): Unicode name "O" in Verzeichnis could be confused with "0". Warning: inode 128 (0/128): Unicode name "\x1b" in Verzeichnis contains control characters. No segfaults occur. The exit codes are 0 respectively 2. -- System Information: Debian Release: forky/sid APT prefers unstable APT policy: (998, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 6.18.5+deb14-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages xfsprogs depends on: ii libblkid1 2.41.3-3 ii libc6 2.42-10+b1 ii libdevmapper1.02.1 2:1.02.205-2+b1 ii libedit2 3.1-20251016-1 ii libicu76 76.1-4+b1 ii libinih1 61-1+b1 ii liburcu8t64 0.15.5-1 ii libuuid1 2.41.3-3 ii python3 3.13.9-3 ii python3-dbus 1.4.0-1+b1 xfsprogs recommends no packages.
