The initial Diffie-Hellman computation made direct use of the MPI library because the crypto module did not support DH at the time. Now that KPP is implemented, KEYCTL_DH_COMPUTE should use it to get rid of duplicate code and leverage possible hardware acceleration. This fixes an issue whereby the input to the KDF computation would include additional uninitialized memory when the result of the Diffie-Hellman computation was shorter than the input prime number.

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.
