Summary: V7 FS: corrupted iso9660 fs recognized as V7 FS, causes
BUG()
Product: File System
Version: 2.5
KernelVersion: 2.6.25.4
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: fs_other at kernel-bugs.osdl.org
ReportedBy: sliedes at cc.hut.fi
Latest working kernel version:
Earliest failing kernel version:
Distribution: Debian sid (unstable)
Hardware Environment: qemu x86
Software Environment: Minimal Debian sid
Problem Description:
The attached files, which are actually (intentionally) corrupted iso9660
filesystems, are recognized as V7 FS, whatever that is. Attempts to use the
filesystem then results in an oops, which probably doesn't speak highly of that
filesystem's robustness against corrupted filesystems.
Steps to reproduce:
For hdb.10007430.gz:
1. gunzip the image
2. mount the image with mount hdb.10007430 /mnt -o loop (it should be
recognized as V7 FS)
3. umount /mnt - oops
For hdb.20005046.gz:
1. gunzip the image
2. mount the image with mount hdb.20005046 /mnt -o loop (it should be
recognized as V7 FS)
3. cd /mnt
4. cat a/b - oops
