David Howells 585f9f6aef crypto/krb5, rxrpc: Fix lack of pre-decrypt/pre-verify length checks
[ Upstream commit 2b50aceafe ]

Change the krb5 crypto library to provide facilities to precheck the length
of the message about to be decrypted or verified.

Fix AF_RXRPC to make use of this to validate DATA packets secured with
RxGK.

Fixes: 9d1d2b5934 ("rxrpc: rxgk: Implement the yfs-rxgk security class (GSSAPI)")

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.
