Bug 71091 – util-linux 2.12i can't mount my crypto fs

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Rene Gass 2004-11-13 14:06:42 UTC]

I've updated from util-linux-2.12b-r1 to 2.12i today. Now I get
"Error: Password must be at least 20 characters." when mounting my crypto filesystem. Reverting to 2.12b-r1 resolved the issue. I've found on Google that losetup seems to be responsible for this. The filesystem was created under Linux 2.4.24 and is not using dm-crypt, if that is of any relevance. It is declared in fstab like this:

/dev/hda2 /mnt/mountpoint ext3 noauto,noatime,loop,encryption=twofish-256,user 0 0

Reproducible: Always
Steps to Reproduce:
mount /mnt/mountpoint
Actual Results:  
"Error: Password must be at least 20 characters."

Expected Results:  
The filesystem should be mounted.

I got antother problem with the 2.12i ebuild. After installing it i could not mount my aes-256 crypto filesystem. 
i tried it with: "mount /dev/hda2 /home -o encryption=aes-256" as usual.
i got following error:
ioctl: LOOP_CLR_FD: Device or resource busy
mount: you must specify the filesystem type

With util-linux-2.12b-r1 it was ok, after emerging the old  util-linux-2.12b-r1 back I could mount my partition again.

i am using ~86 as keyword and using the gcc-3.4.3 compiler.

[Comment 2 Marcin Kryczek (RETIRED) 2004-11-14 16:32:32 UTC]

to devs:
i saw, you've enabled loop-aes support in 2.12i and disabled it in 2.12i-r1. i'm wondering if there's possibility to modify ebuild to chose the correct patch by some USE flag? what do you think about it?

[Comment 3 SpanKY 2004-11-16 06:06:32 UTC]

use 2.12i-r1

[Comment 4 Rene Gass 2004-11-16 16:47:40 UTC]

Works for me now, thanks!

[Comment 5 Rene Gass 2005-01-11 13:25:37 UTC]

I've updated to util-linux-2.12p today and this bug has reappeared. Going back to 2.12i-r1 again has solved the problem.

[Comment 6 SpanKY 2005-01-11 14:57:17 UTC]

USE=old-crypto emerge util-linux

dont post unrelated bugs

[Comment 10 Rene Gass 2005-01-13 15:10:08 UTC]

Mike,

I am aware that this is an ICE. But the current version of util-linux is neither compilable nor usable by me and probably others as well. IIRC other packages have patches that correct compiler bugs, especially WRT mmx/sse, so I thought that was the way to go here, too. Should I rather file a bug report for gcc at bugs.gentoo.org? Should I file no bug report here at all?

[Comment 11 Rene Gass 2005-01-17 14:28:58 UTC]

Ok, I've updated to gcc-3.4.3.20050110 today, and util-linux-2.12p compiles with USE="old-crypto". Nevertheless, I'm getting "Error: Password must be at least 20 characters."

Any ideas?
