Steven J. Magnani 70f19f5869 udf: Don't corrupt unalloc spacetable when writing it ... For a UDF filesystem configured with an Unallocated Space Table, a filesystem operation that triggers an update to the table results in on-disk corruption that prevents remounting: udf_read_tagged: tag version 0x0000 != 0x0002 || 0x0003, block 274 For example: 1. Create a filesystem $ mkudffs --media-type=hd --blocksize=512 --lvid=BUGTEST \ --vid=BUGTEST --fsid=BUGTEST --space=unalloctable \ /dev/mmcblk0 2. Mount it # mount /dev/mmcblk0 /mnt 3. Create a file $ echo "No corruption, please" > /mnt/new.file 4. Umount # umount /mnt 5. Attempt remount # mount /dev/mmcblk0 /mnt This appears to be a longstanding bug caused by zero-initialization of the Unallocated Space Entry block buffer and only partial repopulation of required fields before writing to disk. Commit 0adfb339fd64 ("udf: Fix unalloc space handling in udf_update_inode") addressed one such field, but several others are required. Signed-off-by: Steven J.
