Ingo Franzki d632c0478d s390/pkey: Add sysfs attributes to emit protected key blobs
Add binary read-only sysfs attributes for the pkey module
that can be used to read random protected keys from.
Keys are read from these attributes using a cat-like interface.

A typical use case for those keys is to encrypt a swap device
using the paes cipher. During processing of /etc/crypttab, the
random protected key to encrypt the swap device is read from
one of the attributes.

The following attributes are added:
  protkey/aes_128
  protkey/aes_192
  protkey/aes_256
  protkey/aes_128_xts
  protkey/aes_256_xts
Each attribute emits a protected key blob for the corresponding
key size and cipher mode.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
