Hi, the reported problems seems like you have misconfigured kernel or related tools. I can only suggest you to split debugging to several steps to isolate the problems (I guess is is not only one problem here). But otherwise this is quite specific issue, maybe some specific platform list (or dm-devel) would be more appropriate.

First be sure it is working without any crypto: 0) You have to bee root with CAP_SYSADMIN capability, otherwise device-mapper IOCTLs will be rejected. 1) Use dmsetup (if you are able to compile libdevmapper library, this should trivial. 2) Try to setup simple device-mapper device that does not require userspace interaction, for example dm-zero (of size 8 sectors, IOW 4kB): # dmsetup create test --table "0 8 zero" # dmsetup table test 0 8 zero # blockdev --getsz /dev/mapper/test 8 # dmsetup remove test This must work (you need dm-zero module though; if not available, repeat with "error" mandatory target). If you see failures, the problem is in device-mapper kernel subsystem configuration. You are not using udev, so device nodes are created by libdevmapper library. ALso check SELinux and similar access control (if used) etc. 3) Once above works, try to introduce dm-crypt (replace /dev/sdb with your device), this will map first 4kB as ciphertext device (the key is intentionally not random here :) # dmsetup create test --table "0 8 crypt aes-xts-plain64 0000111122223333444455556666777788889999aaaabbbbccccddddeeeeffff 0 /dev/sdb 0" # dmsetup table --showkeys test: 0 8 crypt aes-xts-plain64 0000111122223333444455556666777788889999aaaabbbbccccddddeeeeffff 0 8:16 0 # dmsetup remove test If it works, kernel support should be ok, now run cryptsetup again and if it is failing, report full debug log again.
