Bugzilla Bug 206747

For several times in the past, updating util-linux broke my crypto fs (and
according to bugzilla many more). Now it happend again after trying 2.13.1.
Running 2.13-r3 worked fine before for several weeks. Also 2.13.0.1 is not
doing well so I downgraded to 2.13-r2 (as long as -r3 seems to be removed from
portage).

Using a "wrong" version just throws the standard error:

# mount /crypto/
Password:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

I'm using Blowfish, this is the relevant part from /etc/fstab:

/dev/sda2               /crypto         reiserfs       
encryption=blowfish,noatime,noauto       0 0

please review the bug reporting guide:
 http://www.gentoo.org/doc/en/bugzilla-howto.xml#doc_chap6

you need to include:
 - emerge --info
 - emerge util-linux -pv
 - the tail of `dmesg` like the error from mount states

also, please explain what you mean by "2.13.0.1 is not doing well" as that
version should function pretty much exactly the same as 2.13-r2

Hm, 2.13.0.1 ist just not working (the same way like 2.13.1), 2.13-r2 (and -r3
which i run before) worked fine. Again, this happens every other update of
util-linux so it might be known issue in updating util-linux.

# emerge -pv util-linux

These are the packages that would be merged, in order:

dmesg just tells:

i'm guessing you're using loop-aes functionality

you need to have USE=loop-aes in newer versions of util-linux ... older
versions enabled it via USE=crypt

ive added a message to the ebuild to note this change

Remark for other frustrated users:

This bug disallows swaping with random encryption keys. /etc/fstab:
/dev/hda2       none        swap        sw,loop=/dev/loop1,encryption=twofish

$ swapon /dev/hda2
/dev/hda2: Invalid argument

merging 2.13.1 +loop-aes gets back the functionality.
