-+README - ocf-linux-20071215
-+---------------------------
-+
-+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:
-+
-+ 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

-+ * -----
-+ * Flags is the bitwise "or" values for command configuration. A single
-+ * encrypt direction needs to be set:
-+ *
-+ * HIFN_ENCODE or HIFN_DECODE
-+ *
-+ * To use cryptography, a single crypto algorithm must be included:

-+ * To use authentication is used, a single MAC algorithm must be included:

-+ * By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
-+ * If the value below is set, hash values are truncated or assumed

-+ * Function: hifn_crypto
-+ *
-+ * Purpose: Called by external drivers to begin an encryption on the

-+ *
-+ * Blocking/Non-blocking Issues
-+ * ============================
-+ * The driver cannot block in hifn_crypto (no calls to tsleep) currently.
-+ * hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
-+ * room in any of the rings for the request to proceed.
-+ *
-+ * Return Values
-+ * =============
-+ * 0 for success, negative values on error
-+ *
-+ * Defines for negative error codes are:
-+ *
-+ * HIFN_CRYPTO_BAD_INPUT : The passed in command had invalid settings.
-+ * HIFN_CRYPTO_RINGS_FULL : All DMA rings were full and non-blocking
-+ * behaviour was requested.

-+ *
-+ * ---------------------------------------------------------------------------
-+ *
-+ * NOTES:
-+ *
-+ * The Freescale SEC (also known as 'talitos') resides on the
-+ * internal bus, and runs asynchronous to the processor core. It has
-+ * a wide gamut of cryptographic acceleration features, including single-
-+ * pass IPsec (also known as algorithm chaining). To properly utilize
-+ * all of the SEC's performance enhancing features, further reworking
-+ * of higher level code (framework, applications) will be necessary.
-+ *
-+ * The following table shows which SEC version is present in which devices:
-+ *
-+ * Devices SEC version
-+ *
-+ * 8272, 8248 SEC 1.0
-+ * 885, 875 SEC 1.2
-+ * 8555E, 8541E SEC 2.0
-+ * 8349E SEC 2.01
-+ * 8548E SEC 2.1
-+ *
-+ * The following table shows the features offered by each SEC version:
-+ *
-+ * Max. chan-
-+ * version Bus I/F Clock nels DEU AESU AFEU MDEU PKEU RNG KEU
-+ *
-+ * SEC 1.0 internal 64b 100MHz 4 1 1 1 1 1 1 0
-+ * SEC 1.2 internal 32b 66MHz 1 1 1 0 1 0 0 0
-+ * SEC 2.0 internal 64b 166MHz 4 1 1 1 1 1 1 0
-+ * SEC 2.01 internal 64b 166MHz 4 1 1 1 1 1 1 0
-+ * SEC 2.1 internal 64b 333MHz 4 1 1 1 1 1 1 1
-+ *
-+ * Each execution unit in the SEC has two modes of execution; channel and
-+ * slave/debug. This driver employs the channel infrastructure in the
-+ * device for convenience. Only the RNG is directly accessed due to the
-+ * convenience of its random fifo pool. The relationship between the
-+ * channels and execution units is depicted in the following diagram:
-+ *
-+ * ------- ------------
-+ * ---| ch0 |---| |
-+ * ------- | |
-+ * | |------+-------+-------+-------+------------
-+ * ------- | | | | | | |
-+ * ---| ch1 |---| | | | | | |
-+ * ------- | | ------ ------ ------ ------ ------
-+ * |controller| |DEU | |AESU| |MDEU| |PKEU| ... |RNG |
-+ * ------- | | ------ ------ ------ ------ ------
-+ * ---| ch2 |---| | | | | | |
-+ * ------- | | | | | | |
-+ * | |------+-------+-------+-------+------------
-+ * ------- | |
-+ * ---| ch3 |---| |
-+ * ------- ------------
-+ *
-+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
-+ * and, at the same time, ch1 may drive a message digest operation
-+ * to the mdeu. Each channel has an input descriptor FIFO, and the
-+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
-+ * a buffer overrun error is triggered. The controller is responsible
-+ * for fetching the data from descriptor pointers, and passing the
-+ * data to the appropriate EUs. The controller also writes the
-+ * cryptographic operation's result to memory. The SEC notifies
-+ * completion by triggering an interrupt and/or setting the 1st byte
-+ * of the hdr field to 0xff.
-+ *
-+ * TODO:
-+ * o support more algorithms
-+ * o support more versions of the SEC
-+ * o add support for linux 2.4
-+ * o scatter-gather (sg) support
-+ * o add support for public key ops (PKEU)
-+ * o add statistics
