With Ubuntu 14.04 and linux-image-3.13.0-83 it is caused by a kernel<->userland breakage. See:
https://lkml.org/lkml/2015/12/29/383
It is caused by [crypto: af_alg - Disallow bind/setkey/... after accept(2)] added to 3.13.0-80.124 with [ Upstream Kernel Changes ].

I've patched cryptsetup-1.6.1 to handle it. See attached patch.

The cryptsetup bundled with Ubuntu 14.04 tries to change the socket after accepting it while the newer kernel doesn't allow changes after accepting the connection.

Se6 seems using a newer Ubuntu version, so maybe it's a different cause there. Or maybe the newer 4.5 kernel reverts those upstream patches!?
