Hello,

I am planing to make dm-crypt and cryptsetup able to
handle FreeBSD's GEOM_ELI crypted devices (without its
integrity stuff).

In the kernel modul there would be minor changes
concerning two more IV generators needed to add:
First, because of a slightly different handling of plain type
(it uses offsets instead of sectors).
Second, GEOM_ELI uses CBC with unpredictable IV instead of
ESSIV Mode.

Additionally cryptsetup must be patched to be able
to deal with the metadata structure of GEOM_ELI devices.

Would there be any interests in committing me this code
to the upstream?

Kind regards.
