Thorsten Blum c637f3e4a5 crypto: testmgr - Add missing DES weak and semi-weak key tests
Ever since commit da7f033ddc ("crypto: cryptomgr - Add test
infrastructure"), the DES test suite has tested only one of the four
weak keys and none of the twelve semi-weak keys.

DES has four weak keys and twelve semi-weak keys, and the kernel's DES
implementation correctly detects and rejects all of these keys when the
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS flag is set. However, only a single weak
key was being tested. Add tests for all 16 weak and semi-weak keys.

While DES is deprecated, it is still used in some legacy protocols, and
weak/semi-weak key detection should be tested accordingly.

Tested on arm64 with cryptographic self-tests.

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.
