Zilin Guan 6c1151d53c tipc: use kfree_sensitive() for aead cleanup 
[ Upstream commit c8ef20fe72 ]

The tipc_aead_free() function currently uses kfree() to release the aead
structure. However, this structure contains sensitive information, such
as key's SALT value, which should be securely erased from memory to
prevent potential leakage.

To enhance security, replace kfree() with kfree_sensitive() when freeing
the aead structure. This change ensures that sensitive data is explicitly
cleared before memory deallocation, aligning with the approach used in
tipc_aead_init() and adhering to best practices for handling confidential
information.

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 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.
