[Solved] losetup/truecrypt/cryptsetup hard freeze on zfs and kernel

timemaster · 2015-07-18 00:48:25

Hello,
I am having a freeze with truecrypt when mouting a container since last updates. Tried four times with the same outcome.
When mounting the container, the computer completly froze :
- mouse animation (of mounting) stop rotating, and mouse cannot be moved
- cannot switch to a console or log terminal
- sysrequest keys does not work
- keyboard light on the keybord does NOT flash, like a normal kernel panic

looking at my last pacman upgrade, there is only a few component, and upgrade the kernel from 4.0.7-2 to 4.1.2-2 is likely the culprit.
anyone having this issue other than me ?

edit : rollbacking the the whole update fixed the issue, so it's probably the kernel.

I am experiencing exactly the same issue.

Hello,

I, and others in my group, had this problem too.

I now use tcplay to create and open my tc containers and devices. To automate the mount I made a script:
https://bbs.archlinux.org/viewtopic.php?id=192992

meccanus · 2015-07-19 09:02:13

Actually both veracrypt and tcplay hang my computer.
Any hints about possible causes or anything I can do to trace them?
TC not working is a huge problem for me.

tcplay and 4.1.2-2 work fine for me...

graysky · 2015-07-19 09:19:19

Sidebar - Maybe you should switch to luks.

meccanus · 2015-07-19 10:40:04

Tried tcplay following step by step https://wiki.archlinux.org/index.php/Tcplay
As soon as I losetup /dev/loop0 /path/to/tc/container.tc the system halts.
This happens with the latest kernel (4.1.2-2 ) + zfs + latest tcplay.
I don't know where to start to find a solution.
I might switch to encfs or whatever in the future, but would really like to be able to open my container right now
Thank you for any advice.

timemaster · 2015-07-19 13:41:39

Is it only me and meccanus that are having this problem while running the container on a zfs filesystem ? (could this be only happening for people with zfs?)

graysky - luks is the better aporoach maintenance and security wise, but there is no good graphical interface to using it from what I know. Feel free to recomment a good user interface. same reason herOldMan has been doing a little script, by using zenity you get a minimal graphical interface and don't need to cryptsetup openLuks fron the terminal every darm time.

graysky · 2015-07-19 13:48:00

Why do you need a gui? You can setup to automount when you boot via /etc/crypttab or just use a script that does it on demand. See the luks wiki for the former or this for the later:

#!/bin/bash

if [[ ! -b /dev/mapper/porn ]]; then
	sudo cryptsetup open /dev/sdb2 porn
	[[ $? -ne 0 ]] && exit 1
fi

mountpoint -q /media/porn || sudo mount -o noatime /dev/sdb2 /media/porn

I did some more tests:
- losetup on other files (an iso) fails too.
- cryptsetup freezes my pc as well.

I have been searching on the internet for a while but couldn't find anything useful.

You might be able to get kernel message and crash through a connected ethernet/serial/usb console. Once connected, all your kernel message will be forwarded to another computer. You then do the operation that makes it crash, and even if this computer is crashed, you should be able to see kernel oops or crash on the remote computer.
NetConsole seems to be the easy way to set this without requiring com port. serial/usb can be setup with the "console" kernel parameters.

Could be; I am using ext4.

meccanus · 2015-07-19 17:09:59

I can confirm that the problem appears to be related to zfs.
I moved my TC containers on an ext4 partition and could mount them with no issue from there.

timemaster · 2015-07-19 20:37:37

Hummm... if it's related to zfs somehow, it as weird as it get, as the kernel stacktrace is not related to zfs at all. I'll try to mount it on a different filesystem too later.

kernel stacktrace on crash catched with netconsole :

changed the subject of this thread
meccanus, I confirm your finding
- truecrypt works on both xfs and ext4, but crash on zfs
- losetup also crash on zfs, with similar oops than truecrypt (that anyway internally probably use losetup to mount that container) - trace below.
I created an issue on zfsonlinux github project.
