commit27c7003697upstream. If dm-crypt uses authenticated mode with separate MAC, there are two concatenated part of the key structure - key(s) for encryption and authentication key. Add a missing check for authenticated key length. If this key length is smaller than actually provided key, dm-crypt now properly fails instead of crashing.

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.
