Description of problem: Setting up encrypted loopback like specified in the man page does not work. Version-Release number of selected component (if applicable): util-linux-2.13-0.20.4 kernel-2.6.17-1.2187_FC5 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: Password: ioctl: LOOP_SET_STATUS: Invalid argument Expected results: Password: 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digits): # and the device gets attached with encryption enabled Additional info: The man page appears to be somewhat outdated.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.
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.
The man page updated in the devel branch.
The man page has been updated in FC6.
