From 7e8dec918ef8e0f68b4937c3c50fa57002077a4d Mon Sep 17 00:00:00 2001 From: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Date: Mon, 7 Nov 2011 15:16:37 +0200 Subject: crypto: GnuPG based MPI lib - additional sources (part 4) Adds the multi-precision-integer maths library which was originally taken from GnuPG and ported to the kernel by (among others) David Howells. This version is taken from Fedora kernel 2.6.32-71.14.1.el6. The difference is that checkpatch reported errors and warnings have been fixed. This library is used to implemenet RSA digital signature verification used in IMA/EVM integrity protection subsystem. Due to patch size limitation, the patch is divided into 4 parts. This code is unnecessary for RSA digital signature verification, but for completeness it is included here and can be compiled, if CONFIG_MPILIB_EXTRA is enabled.
