Cryptsetup and the 3.18.27-1 Kernel

[hooper35]

I'm using the great B3 install by MouettE. Thanks MouettE!!

I'm trying to encrypt a partition with cryptsetup but get the error.

=========
Failed to setup dm-crypt key mapping for device /dev/sda3.
Check that kernel supports aes-xts-plain64 cipher (check syslog for more info).
Command failed with code 22: Failed to setup dm-crypt key mapping for device /dev/sda3.
Check that kernel supports aes-xts-plain64 cipher (check syslog for more info)
=========

Has anyone seen this error and solved it? I have searched various groups and it looks like I may need to change kernel version, but that seems quite drastic.

Any help gratefully received.

Hello,

The option is probably missing from the kernel configuration. I'm on holiday right now but I will take a look when I get back and make a new release if possible.

Thanks MouettE

Good news I did some tests on a newer 3.18.44 kernel and it seems to work (I previously tried with 3.18.27 and did reproduce the problem). It was a kernel bug.

I'm currently compiling the new versions of the kernel packages for the B2 and the B3 and they will be pushed to the repo in a couple of days. You will be able to do an apt-get upgrade and reboot to correct the problem.

That's great. Thanks very much. I'll be able to do my backups again!

I tried it today and the update came through. The bug has gone!

Thanks MouettE

Both B2 and B3 now have a new 3.18.44-1 kernel available.

MouettE,

Me again, with the same issue, but with the Stretch install for B3.

Enter passphrase for /dev/sda3:
device-mapper: reload ioctl on temporary-cryptsetup-10055 failed: Invalid argument
Failed to setup dm-crypt key mapping for device /dev/sda3.
Check that kernel supports aes-xts-plain64 cipher (check syslog for more info).

Is this the kernel again? If so, would it be possible to update it again?

Thanks

I am very busy at the moment but I have created an issue on the github repo and I will take a look as soon as I can.

Best,

[hooper35]

Thanks. Very kind of you.

I've compiled a new kernel with added crypto modules, I've managed to boot my b3 with so it should work OK, can you validate if it fixes your issue ? You just need to download it at http://repo.excito.org/testing/bubba3-k ... _armel.deb and manually install it with dpkg -i bubba3-kernel_4.9.88-1_armel.deb.

Let me know, if it's OK I'll release it on the official repository.

[hooper35]

MouettE,

That has worked. Thanks!

[MouettE]

Good to know. Let me know if there is any issue. I will make an official release in the next couple of weeks.

MouettE,

I've just had to reinstall my stretch partition and have got the kernel error again.

device-mapper: reload ioctl on temporary-cryptsetup-17520 failed: Invalid argument
Failed to setup dm-crypt key mapping for device /dev/sda3.
Check that kernel supports aes-xts-plain64 cipher (check syslog for more info).

Is this the same thing as before?

MouettE,

I installed your previous fix - which worked - but it did this:

dpkg: warning: downgrading bubba3-kernel from 1:4.9.135-1 to 1:4.9.88-1
