Add support for deriving protected keys from clear key token for AES xts and HMAC keys via PCKMO instruction. Add support for protected key generation and unwrap of protected key tokens for these key types. Furthermore 4 new sysfs attributes are introduced: - /sys/devices/virtual/misc/pkey/protkey/protkey_aes_xts_128 - /sys/devices/virtual/misc/pkey/protkey/protkey_aes_xts_256 - /sys/devices/virtual/misc/pkey/protkey/protkey_hmac_512 - /sys/devices/virtual/misc/pkey/protkey/protkey_hmac_1024 Signed-off-by: Harald Freudenberger <freude@linux.ibm.com> Reviewed-by: Ingo Franzki <ifranzki@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
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 reStructuredText markup notation.
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.
