Message-Id: <2934572c0461726bdbcb30552f90b9caf5823cae.1318598705.git.dmitry.kasatkin@intel.com> Date: Fri, 14 Oct 2011 16:45:21 +0300 From: Dmitry Kasatkin <dmitry.kasatkin@...el.com> To: linux-security-module@...r.kernel.org Cc: linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org, zohar@...ux.vnet.ibm.com, dhowells@...hat.com, herbert@...dor.apana.org.au Subject: [PATCH v2.1 3/7] crypto: GnuPG based MPI lib - make files (part 3) 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.
