[Bionic][PATCH 0/1] UBUNTU: SAUCE: s390/crypto: Adjust s390 aes and paes cipher

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1762353


== Bionic Justification ==
Setting up two or more plain end-to-end encrypted disks using 'cryptsetup'
fails when using a cipher based on the protected key mechanism.
The setup needs the paes and pkey modules loaded, the former providing the
paes-xts-plain64 cipher (cat /proc/crpyto |grep paes).

A second attempt to establish an end-to-end encrypted disk fails
with : "device-mapper: reload ioctl on failed: No such file or directory."

The problem is independent of the second encrypted disk being based on a second DASD or second partition on one DASD.

This patch is not upstream as of yet.
Tentativ upstream targert is kernel 4.17 (merge window currently open).

== Fix ==
