+README - ocf-linux-20100530
+###########################
This README provides instructions for getting ocf-linux compiled and
-operating in a generic linux environment. For other information you
-might like to visit the home page for this project:
+operating in a generic linux environment. Other information on the project
+can be found at the home page:
http://ocf-linux.sourceforge.net/
-Adding OCF to linux
--------------------
+Embedded systems and applications requiring userspace acceleration will need
+to patch the kernel source to get full OCF support. See "Adding OCF to
+linux source" below. Otherwise the "OCF Quickstart" that follows is the
+easiest way to get started.
- 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:
+If your goal is to accelerate Openswan on Ubuntu or CentOS, you may find
+that the required binaries are already available on openswan.org:
- * mknod /dev/crypto c 10 70
+ ftp://ftp.openswan.org/ocf/
+ ftp://ftp.openswan.org/openswan/binaries/ubuntu/
- * to add OCF to your kernel source, you have two options. Apply
- the kernel specific patch:
+#####################################################
+OCF Quickstart for Ubuntu/Others (including Openswan)
+#####################################################
- 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 2.6.33 to include the ocf code under crypto/ocf.
- Here's how to add it:
+This section provides instructions on how to quickly add kernel only support
+for OCF to a GNU/Linux system. It is only suitable for in-kernel use such as
+Openswan MAST/KLIPS.
- for 2.4.35 (and later)
+If the target is an embedded system, or, userspace acceleration of
+applications such as OpenVPN and OpenSSL, the section below titled
+"Adding OCF to linux source" is more appropriate.
- cd linux-2.4.35/crypto
- tar xvzf ocf-linux.tar.gz
- cd ..
- patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
+Before building kernel only support for OCF ensure that the appropriate
+linux-headers package is installed:
- for 2.6.23 (and later), find the kernel patch specific (or nearest)
- to your kernel versions and then:
+ cd ocf
+ make ocf_modules
+ sudo make ocf_install
+ OCF_DIR=`pwd` # remember where OCF sources were built
- cd linux-2.6.NN/crypto
- tar xvzf ocf-linux.tar.gz
- cd ..
- patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
+At this point the ocf, cryptosoft, ocfnull, hifn7751 and ocf-bench modules
+should have been built and installed. The OCF installation can be tested
+with the following commands:
- 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:
+ modprobe ocf
+ modprobe cryptosoft
+ modprobe ocf-bench
+ dmesg | tail -5
- cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
+The final modprobe of ocf-bench will fail, this is intentional as ocf-bench
+is a short lived module that tests in-kernel performance of OCF. If
+everything worked correctly the "dmesg | tail -5" should include a line
+like:
- so that you can build the kernel crypto support needed for the cryptosoft
- driver.
+ [ 583.128741] OCF: 45133 requests of 1488 bytes in 251 jiffies (535.122 Mbps)
- * 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).
+This shows the in-kernel performance of OCF using the cryptosoft driver.
+For addition driver load options, see "How to load the OCF modules" below.
- * 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:
+If the intention is to run an OCF accelerated Openswan (KLIPS/MAST) then use
+these steps to compile openswan downloaded from openswan.org (2.6.34 or later).

- * patch your openssl-0.9.8n code with the openssl-0.9.8n.patch.
- (NOTE: there is no longer a need to patch ssh). The patch is against:
- openssl-0_9_8e
+The rest of this document is only required for more complex build
+requirements.
- If you need a patch for an older version of openssl, you should look

- openssl versions.
+##########################
+Adding OCF to linux source
+##########################
- openssl-0.9.8n.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.
+It is recommended that OCF be built as modules as it increases the
+flexibility and ease of debugging the system.
- * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
- tools for testing OCF (ie., cryptotest).
+Ensure that the system has /dev/crypto for userspace access to OCF:
-How to load the OCF drivers
----------------------------
+ mknod /dev/crypto c 10 70
- First insert the base modules:
+Generate the kernel patches and apply the appropriate one.
- insmod ocf
- insmod cryptodev
+ cd ocf
+ make patch
- You can then install the software OCF driver with:
+This will provide three files:
- insmod cryptosoft
+ linux-2.4.*-ocf.patch
+ linux-2.6.*-ocf.patch
+ ocf-linux-base.patch
- and one or more of the OCF HW drivers with:
+If either of the first two patches applies to the targets kernel, then one
+of the following as required:
- insmod safe
- insmod hifn7751
- insmod ixp4xx
- ...
+ cd linux-2.X.Y; patch -p1 < linux-2.4.*-ocf.patch
+ cd linux-2.6.Y; patch -p1 < linux-2.6.*-ocf.patch
- 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:
+Otherwise, locate the appropriate kernel patch in the patches directory and
+apply that as well as the ocf-linux-base.patch using '-p1'.
- insmod ocf crypto_debug=1
- insmod cryptodev cryptodev_debug=1
- insmod cryptosoft swcr_debug=1
+When using a linux-2.4 system on a non-x86 platform, the following may be
+required to build cryptosoft:
- You may load more than one OCF crypto driver but then there is no guarantee
- as to which will be used.
+ cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
- You can also enable debug at run time on 2.6 systems with the following:
+When using cryptosoft, for simplicity, enable all the crypto support in the
+kernel except for the test driver. Likewise for the OCF options. Do not
+enable OCF crypto drivers for HW that is not present (for example the ixp4xx
+driver will not compile on non-Xscale systems).
- 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
- ...
+Make sure that cryptodev.h from the ocf directory is installed as
+crypto/cryptodev.h in an include directory that is used for building
+applications for the target platform. For example on a host system that
+might be:
+ /usr/include/crypto/cryptodev.h
+
+Patch the openssl-0.9.8r code the openssl-0.9.8r.patch from the patches
+directory. There are many older patch versions in the patches directory
+if required.
+
+The openssl patches provide the following functionality:
+
+ * 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 the crypto-tools directory for the target to obtain a userspace
+testing tool call cryptotest.
+
+###########################
+How to load the OCF modules
+###########################
+
+First insert the base modules (cryptodev is optional, it is only used
+for userspace acceleration):
+
+ modprobe ocf
+ modprobe cryptodev
+
+Load the software OCF driver with:
+
+ modprobe cryptosoft
+
+and zero or more of the OCF HW drivers with:
+
+ modprobe safe
+ modprobe hifn7751
+ modprobe ixp4xx
+ ...
+
+All the drivers take a debug option to enable verbose debug so that
+OCF operation may be observed via "dmesg" or the console. For debug
+load the modules as:
+
+ modprobe ocf crypto_debug=1
+ modprobe cryptodev cryptodev_debug=1
+ modprobe cryptosoft swcr_debug=1
+
+More than one OCF crypto driver may be loaded but then there is no
+guarantee as to which will be used (other than a preference for HW
+drivers over SW drivers by most applications).
+
+It is also possible to enable debug at run time on linux-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
+ ...
+
+The ocf-bench driver accepts the following parameters:
+
+ request_q_len - Maximum number of outstanding requests to OCF
+ request_num - run for at least this many requests
+ request_size - size of each request (multiple of 16 bytes recommended)
+ request_batch - enable OCF request batching
+ request_cbimm - enable OCF immediate callback on completion
+
+For example:
+
+ modprobe ocf-bench request_size=1024 request_cbimm=0
+

+ * This file defines five types of data structures: singly-linked lists,
+ * lists, simple queues, tail queues, and circular queues.
+ *
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction. Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may only be traversed in the forward direction.
+ *
+ * A simple queue is headed by a pair of pointers, one the head of the
+ * list and the other to the tail of the list. The elements are singly
+ * linked to save space, so elements can only be removed from the
+ * head of the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the
+ * list. A simple queue may only be traversed in the forward direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * A circle queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or after
+ * an existing element, at the head of the list, or at the end of the list.
+ * A circle queue may be traversed in either direction, but has a more
+ * complex end of list detection.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.
