ocf-linux compiled and ++operating in a generic linux environment. For other information you ++might like to visit the home page for this project: ++ ++ http://ocf-linux.sourceforge.net/ ++ ++Adding OCF to linux ++------------------- ++ ++ Not much in this file for now, just some notes. I usually build ++ the ocf support as modules but it can be built into the kernel as ++ well. To use it: ++ ++ * mknod /dev/crypto c 10 70 ++ ++ * to add OCF to your kernel source, you have two options. Apply ++ the kernel specific patch: ++ ++ cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1 ++ cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1 ++ ++ if you do one of the above, then you can proceed to the next step, ++ or you can do the above process by hand with using the patches against ++ linux-2.4.35 and 2.6.23 to include the ocf code under crypto/ocf. ++ Here's how to add it: ++ ++ for 2.4.35 (and later) ++ ++ cd linux-2.4.35/crypto ++ tar xvzf ocf-linux.tar.gz ++ cd .. ++ patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch ++ ++ for 2.6.23 (and later), find the kernel patch specific (or nearest) ++ to your kernel versions and then: ++ ++ cd linux-2.6.NN/crypto ++ tar xvzf ocf-linux.tar.gz ++ cd .. ++ patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch ++ ++ It should be easy to take this patch and apply it to other more ++ recent versions of the kernels. The same patches should also work ++ relatively easily on kernels as old as 2.6.11 and 2.4.18. ++ ++ * under 2.4 if you are on a non-x86 platform, you may need to: ++ ++ cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY ++ ++ so that you can build the kernel crypto support needed for the cryptosoft ++ driver. ++ ++ * For simplicity you should enable all the crypto support in your kernel ++ except for the test driver. Likewise for the OCF options. Do not ++ enable OCF crypto drivers for HW that you do not have (for example ++ ixp4xx will not compile on non-Xscale systems). ++ ++ * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as ++ crypto/cryptodev.h in an include directory that is used for building ++ applications for your platform. For example on a host system that ++ might be: ++ ++ /usr/include/crypto/cryptodev.h ++ ++ * patch your openssl-0.9.8i code with the openssl-0.9.8i.patch. ++ (NOTE: there is no longer a need to patch ssh). The patch is against: ++ openssl-0_9_8e ++ ++ If you need a patch for an older version of openssl, you should look ++ to older OCF releases. This patch is unlikely to work on older ++ openssl versions. ++ ++ openssl-0.9.8i.patch ++ - enables --with-cryptodev for non BSD systems ++ - adds -cpu option to openssl speed for calculating CPU load ++ under linux ++ - fixes null pointer in openssl speed multi thread output. ++ - fixes test keys to work with linux crypto's more stringent ++ key checking. ++ - adds MD5/SHA acceleration (Ronen Shitrit), only enabled ++ with the --with-cryptodev-digests option ++ - fixes bug in engine code caching. ++ ++ * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD ++ tools for testing OCF (ie., cryptotest). ++ ++How to load the OCF drivers ++--------------------------- ++ ++ First insert the base modules: ++ ++ insmod ocf ++ insmod cryptodev ++ ++ You can then install the software OCF driver with: ++ ++ insmod cryptosoft ++ ++ and one or more of the OCF HW drivers with: ++ ++ insmod safe ++ insmod hifn7751 ++ insmod ixp4xx ++ ... ++ ++ all the drivers take a debug option to enable verbose debug so that ++ you can see what is going on. For debug you load them as: ++ ++ insmod ocf crypto_debug=1 ++ insmod cryptodev cryptodev_debug=1 ++ insmod cryptosoft swcr_debug=1 ++ ++ You may load more than one OCF crypto driver but then there is no guarantee ++ as to which will be used. ++ ++ You can also enable debug at run time on 2.6 systems with the following: ++ ++ echo 1 > /sys/module/ocf/parameters/crypto_debug ++ echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug ++ echo 1 > /sys/module/cryptosoft/parameters/swcr_debug ++ echo 1 > /sys/module/hifn7751/parameters/hifn_debug ++ echo 1 > /sys/module/safe/parameters/safe_debug ++ echo 1 > /sys/module/ixp4xx/parameters/ixp_debug ++ ... ++ ++Testing the OCF support ++----------------------- ++ ++ run "cryptotest", it should do a short test for a couple of ++ des packets. If it does everything is working. ++ ++ If this works, then ssh will use the driver when invoked as: ++ ++ ssh -c 3des username@host ++ ++ to see for sure that it is operating, enable debug as defined above. ++ ++ To get a better idea of performance run: ++ ++ cryptotest 100 4096 ++ ++ There are more options to cryptotest, see the help. ++ ++ It is also possible to use openssl to test the speed of the crypto ++ drivers. ++ ++ openssl speed -evp des -engine cryptodev -elapsed ++ openssl speed -evp des3 -engine cryptodev -elapsed ++ openssl speed -evp aes128 -engine cryptodev -elapsed ++ ++ and multiple threads (10) with: ++ ++ openssl speed -evp des -engine cryptodev -elapsed -multi 10 ++ openssl speed -evp des3 -engine cryptodev -elapsed -multi 10 ++ openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10 ++ ++ for public key testing you can try: ++ ++ cryptokeytest ++ openssl speed -engine cryptodev rsa -elapsed ++ openssl speed -engine cryptodev dsa -elapsed ++ ++David McCullough ++david_mccullough@securecomputing.com +diff -Nur linux-2.6.30.orig/crypto/ocf/rndtest.c linux-2.6.30/crypto/ocf/rndtest.c +--- linux-2.6.30.orig/crypto/ocf/rndtest.c 1970-01-01 01:00:00.000000000 +0100 ++++ linux-2.6.30/crypto/ocf/rndtest.c 2009-06-11 10:55:27.000000000 +0200 +@@ -0,0 +1,300 @@ ++/* $OpenBSD$ */ ++ ++/* ++ * OCF/Linux port done by David McCullough ++ * Copyright (C) 2006-2007 David McCullough ++ * Copyright (C) 2004-2005 Intel Corporation. ++ * The license and original author are listed below. ++ * ++ * Copyright (c) 2002 Jason L.

Waldemar Brodkorb Date: Thu, 19 Nov 2009 09:53:00 +0100 Subject: rename DEVICE to ADK_TARGET - the name is better, because qemu f.e. is no hardware device - use make TARGET=alix1c to start with a configuration for this target - use make TARGET=alix1c allmodconfig to generate a mostly complete config to build all available packages for this platform as a package The all.config and .defconfig
