Krzysztof Kozlowski 42d5c176b7 crypto: s5p-sss - Close possible race for completed requests
Driver is capable of handling only one request at a time and it stores
it in its state container struct s5p_aes_dev.  This stored request must be
protected between concurrent invocations (e.g. completing current
request and scheduling new one).  Combination of lock and "busy" field
is used for that purpose.

When "busy" field is true, the driver will not accept new request thus
it will not overwrite currently handled data.

However commit 28b62b1458 ("crypto: s5p-sss - Fix spinlock recursion
on LRW(AES)") moved some of the write to "busy" field out of a lock
protected critical section.  This might lead to potential race between
completing current request and scheduling a new one.  Effectively the
request completion might try to operate on new crypto request.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
