The inline ap_dqap function does not return the number of bytes actually written into the message buffer. The calling code inspects the AP message header to figure out what kind of AP message has been received and pulls the length information from this header. This processing may not work correctly in cases where only a fragment of the reply is received. With this patch the ap_dqap inline function now returns the number of actually written bytes in the *length parameter. So the calling function has a chance to compare the number of received bytes against what the AP message header length field states. This is especially useful in cases where a message could only get partially received. The low level reply processing functions needed some rework to be able to catch this new length information and compare it the right way. The rework also deals with some situations where until now the reply length was not correctly calculated and/or set. All this has been heavily tested as the modifications on the reply length information may affect crypto load.

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.
