Description of problem:
after creating a block file (Following the loopback encryption howto), tying to 
issue the following 
command: 
losetup -e des /dev/loop3 /path/tofile 
gives 
ioctl: LOOP_SET_STATUS: Invalid Argument 
 
using -e xor instead of -e des lets it complete.  From what I can gather, this 
means that the 
util-linux doesn't contain some patches that make the des encryption work. 


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  losetup -e des /dev/loop3 /path/tofile (created by dd) 
2.  enter a password 
3.enter a hex offset 

Actual Results:  error:  ioctl: LOOP_SET_STATUS: Invalid Argument 

Expected Results:  the system should have mounted the file via the lookback 
device 
encrypted with DES.
