Namjae Jeon 7a891d4b62 ksmbd: fix wrong signingkey creation when encryption is AES256
MacOS and Win11 support AES256 encrytion and it is included in the cipher
array of encryption context. Especially on macOS, The most preferred
cipher is AES256. Connecting to ksmbd fails on newer MacOS clients that
support AES256 encryption. MacOS send disconnect request after receiving
final session setup response from ksmbd. Because final session setup is
signed with signing key was generated incorrectly.
For signging key, 'L' value should be initialized to 128 if key size is
16bytes.

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.

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.
