Description Kasper Dupont 2006-10-08 00:11:32 UTC
Description of problem:
Setting up encrypted loopback like specified in the man page does not work.

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

How reproducible:
Happens always

Steps to Reproduce:
1. man losetup
2. dd if=/dev/zero of=/file bs=1k count=100
3. losetup -e des /dev/loop0 /file
Actual results:
ioctl: LOOP_SET_STATUS: Invalid argument

Expected results:
Init (up to 16 hex digits):
# and the device gets attached with encryption enabled

Additional info:
The man page appears to be somewhat outdated. The only encryptions mentioned are
DES and XOR. Maybe the only fix needed for this bug is an updated man page.

Comment 1 Karel Zak 2006-10-11 21:19:10 UTC
Cryptoloop is deprecated (in the 2.6 kernel) in favour of dm-crypt. For more
information about dm-crypt see cryptsetup man page.

Well, we should add this note to the losetup man page.

Comment 2 Karel Zak 2006-10-12 10:00:09 UTC
The man page updated in the devel branch.

Comment 3 Karel Zak 2006-11-01 14:19:43 UTC
The man page has been updated in FC6.
