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.
