commit73bf20ef3dupstream. The VMAC template assumes the block cipher has a 128-bit block size, but it failed to check for that. Thus it was possible to instantiate it using a 64-bit block size cipher, e.g. "vmac(cast5)", causing uninitialized memory to be used. Add the needed check when instantiating the template.

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.
