[suse-security] Re: [SLE] Why does loopback encryption only work when loopback is compiled as a module



When "loopback device support" and "Twofish encryption for loopback device" is compiled
INTO the kernel, the "losetup -e twofish /dev/loop0 /encrypted-file" command fails with the 
error: "ioctl: LOOP_SET_STATUS: invalid argument"

If they are compiled as modules, everything works OK.

I have tred it with many versions of the SuSE kernels, and the result is always
the same !.

Any suggestions on how to get it to work.


Thanks in advance
Bo Jacobsen
