Subject: usb_storage issue: A (not so) funny way to (or to not) delete files.
Package: kernel-image-2.6.8-1-386
Version: 2.6.8-10
Severity: grave
1) Kernel
ii kernel-image-2.6.8-1-386 2.6.8-10 Linux kernel image for version
2.6.8 on 386.
ii kernel-image-2.6.8-1-686 2.6.8-10 Linux kernel image for version
2.6.8 on PPro/Celeron/PII/PIII/PIV.
ii kernel-image-2.6.8-1-686-smp 2.6.8-10 Linux kernel image for version
2.6.8 on PPro/Celeron/PII/PIII/PIV SMP.
ii kernel-image-2.6.10-686-smp 01.vanilla Linux kernel binary image for
version 2.6.10-686-smp.
2) Usb storage device physically set to read only
3) Mount it as rw (mount -o rw /dev/sdc1 /media/usb), file system is vfat.
4) mv my_favorite_file /media/usb && echo success
success
5) sync
6) A lot of errors in messages:
SCSI error : <2 0 0 0> return code = 0x8000002
Current sda: sense key Data Protect
Additional sense: Write protected
end_request: I/O error, dev sda, sector 566
Buffer I/O error on device sda1, logical block 509
lost page write due to I/O error on sda1
7) ls -la /media/usb/my_favorite_file
ls: /media/usb/my_favorite_file: No such file or directory
8) The same for rm, the deleted files magically appear after a sync
9) Additionally, but only if the file are a lot (100) and large
(2MByte each one) the sync may take a long time (2 hours)
10) Additionaly after the 2 hour sync I have a oops after unmounting
and disconneting and reconnectting the usb memory.

Note: I don't try to reproduce Points 9) and 10). The kernel
in this case (as you see) was kernel-image-2.6.10-686-smp
The kernel-image-2.6.10-686-smp 01.vanilla is a custom compiled vanilla
kernel (base from debian 686-smp + make oldconfig (all as module))
Severity is set to grave since this bug can cause data loss.
Only for reference: try to mount the memory on with the mandrake kernel
2.6.8.1-13mdk and mount reply with an error:
mount: block device /dev/sdc1 is write protected, mountig read-only.
With the debian kernel you can also mount -o rw /dev/cdrom0,
mount | grep cdrom
/dev/cdrom0 on /media/cdrom0 type iso9660 (rw,noexec,nosuid,nodev)
after you get a error during writing
cp: cannot create regular file `/media/cdrom/file': Read-only file system
I you have any quesition, please reply.
Best Regards,
Daniele
