cryptsetup tcryptOpen doesn't work anymore
Status in cryptsetup package in Ubuntu:
Status in linux package in Ubuntu:
I'm using cryptsetup to open TrueCrypt encrypted NTFS filesystems:
cryptsetup tcryptOpen /dev/sdf2 tcrypt
At least until linux-image-3.13.0-79-generic this work fine.
Booting linux-image-3.13.0-83-generic and running cryptsetup results in:
Required kernel crypto interface not available.
Ensure you have algif_skcipher kernel module loaded.
The module algif_skcipher is loaded, so the tenor of the error message
is wrong, but cryptsetup cannot open the container, so at least there
_is_ some error. Probably it's related to some unsupported instruction
set. With linux-image-3.13.0-83 there are errors in dmesg which are
not present with linux-image-3.13.0-79:
AVX instructions are not detected
