The CCM driver was recently updated to defer the MAC part of the algorithm to a dedicated crypto transform, and a template for instantiating such transforms was added at the same time. However, this new cbcmac template fails to take the alignmask of the encapsulated cipher into account, which may result in buffer addresses being passed down that are not sufficiently aligned. So update the code to ensure that the digest buffer in the desc ctx appears at a sufficiently aligned offset, and tweak the code so that all calls to crypto_cipher_encrypt_one() operate on this buffer exclusively.

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.
