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 ---- /dev/null -+++ b/crypto/ocf/hifn/hifn7751reg.h -@@ -0,0 +1,540 @@ -+/* $FreeBSD: src/sys/dev/hifn/hifn7751reg.h,v 1.7 2007/03/21 03:42:49 sam Exp $ */ -+/* $OpenBSD: hifn7751reg.h,v 1.35 2002/04/08 17:49:42 jason Exp $ */ -+ -+/*- -+ * Invertex AEON / Hifn 7751 driver -+ * Copyright (c) 1999 Invertex Inc.

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 ---- /dev/null -+++ b/crypto/ocf/hifn/hifn7751reg.h -@@ -0,0 +1,540 @@ -+/* $FreeBSD: src/sys/dev/hifn/hifn7751reg.h,v 1.7 2007/03/21 03:42:49 sam Exp $ */ -+/* $OpenBSD: hifn7751reg.h,v 1.35 2002/04/08 17:49:42 jason Exp $ */ -+ -+/*- -+ * Invertex AEON / Hifn 7751 driver -+ * Copyright (c) 1999 Invertex Inc.

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 ---- /dev/null -+++ b/crypto/ocf/hifn/hifn7751reg.h -@@ -0,0 +1,540 @@ -+/* $FreeBSD: src/sys/dev/hifn/hifn7751reg.h,v 1.7 2007/03/21 03:42:49 sam Exp $ */ -+/* $OpenBSD: hifn7751reg.h,v 1.35 2002/04/08 17:49:42 jason Exp $ */ -+ -+/*- -+ * Invertex AEON / Hifn 7751 driver -+ * Copyright (c) 1999 Invertex Inc.
