Mounting corrupted ext3 image results in infinite loop

Mounting corrupted ext3 image results in infinite loop

[Eric Sesterhenn]

hi,

mounting an intentionally corrupted ext3 image results in
an infinite loop during the mount.

The compressed image can be found here:
http://www.cccmz.de/~snakebyte/ext3.57.img.bz2


mount ./cfs/ext3.57.img /media/test -t ext3 -o debug,data=journal -o
loop

gives the following dmesg output

[  159.477815] EXT3-fs error (device loop0): ext3_free_branches: Read
failure, inode=8, block=2147483648
[  159.488844] Aborting journal on device loop0.

[  181.629567] ext3_orphan_cleanup: truncating inode 8 to 1049088 bytes

the ext3_orphan_cleanup message is then repeated forever.

Greetings, Eric
