[SOLVED] loop-aes LOOP_MULTI_KEY_SETUP: Invalid argument

[ultimatedevr]

I'm trying to encrypt a partion with loop-aes w/multi-key support; I've been following the directions in the loop-aes readme (http://loop-aes.sourceforge.net/loop-AES.README, 7.2. Example 2 - Partition backed loop with gpg encrypted key file) and I've gotten to the part where I have to use losetup -F /dev/loop0 to setup the partition so that I can format it, but I get the error LOOP_MULTI_KEY_SETUP: Invalid argument. I can setup the partition when I remove the gpgkey statement in /etc/fstab, but then I don't have the protection of the gpg keys. Ideas? I'm using util-linux-2.14.1 (use flags crypt loop-aes nls unicode), loop-aes-3.2e, sharutils-4.7, and I have the loop module (from the loop-aes package) and cryptoloop module (from the kernel) loaded while setting up the encryption (I've heard that cryptoloop is deprecated, but if it's not loaded then I get a LOOP_SET_STATUS: Invalid argument, requested cipher or key length (256 bits) not supported by kernel)

Nevermid I figured it out; I had to set CONFIG_BLK_DEV_LOOP=n in my kernel's .config to disable the kernel's loopback support and then re-install the loop-aes package. (apparently the check for this in the ebuild CONFIG_CHECK="!BLK_DEV_LOOP" didn't work; it should check if CONFIG_BLK_DEV_LOOP=n, because as it is now, the ebuild will build even if CONFIG_BLK_DEV_LOOP=m, which in my case is what was causing problems)
