[dpdk-dev] [PATCH v2 1/4] crypto/zuc: add driver for ZUC library
Pablo de Lara
pablo.de.lara.guarch at intel.com
Thu Sep 29 04:59:47 CEST 2016
Added new SW PMD which makes use of the libsso SW library,
which provides wireless algorithms ZUC EEA3 and EIA3
in software.
This PMD supports cipher-only, hash-only and chained operations
("cipher then hash" and "hash then cipher") of the following
algorithms:
- RTE_CRYPTO_SYM_CIPHER_ZUC_EEA3
- RTE_CRYPTO_SYM_AUTH_ZUC_EIA3
The ZUC hash and cipher algorithms, which are enabled
by this crypto PMD are implemented by Intel's libsso software
library.

+ZUC Crypto Poll Mode Driver
+===========================
+
+The ZUC PMD (**librte_pmd_zuc**) provides poll mode crypto driver
+support for utilizing Intel Libsso library, which implements F8 and F9 functions
+for ZUC EEA3 cipher and EIA3 hash algorithms.
+
+Features
+--------
+
+ZUC PMD has support for:
+
+Cipher algorithm:
+
+* RTE_CRYPTO_CIPHER_ZUC_EEA3
+
+Authentication algorithm:
+
+* RTE_CRYPTO_AUTH_ZUC_EIA3
+
+Limitations
+-----------
+
+* Chained mbufs are not supported.
+* ZUC (EIA3) supported only if hash offset field is byte-aligned.
+* ZUC (EEA3) supported only if cipher length, cipher offset fields are byte-aligned.
+
+Installation
+------------
+
+To build DPDK with the ZUC_PMD the user is required to download
+the export controlled ``libsso_zuc`` library, by requesting it from
+`<https://networkbuilders.intel.com/network-technologies/dpdk>`_.
+Once approval has been granted, the user needs to log in
+`<https://networkbuilders.intel.com/dpdklogin>`_
+and click on "ZUC Library" link, to download the library.
+After downloading the library, the user needs to unpack and compile it
+on their system before building DPDK::
+
+ make
+
+Initialization
+--------------
+
+In order to enable this virtual crypto PMD, user must:
+
+* Export the environmental variable LIBSSO_ZUC_PATH with the path where
+ the library was extracted (zuc folder).
+
+* Build the LIBSSO_ZUC library (explained in Installation section).
+
+* Build DPDK as follows:
+
+.. code-block:: console
+
+ make config T=x86_64-native-linuxapp-gcc
+ sed -i 's,\(CONFIG_RTE_LIBRTE_PMD_ZUC\)=n,\1=y,' build/.config
+ make
+
+To use the PMD in an application, user must:
+
+* Call rte_eal_vdev_init("crypto_zuc") within the application.
+
+* Use --vdev="crypto_zuc" in the EAL options, which will call rte_eal_vdev_init() internally.
+
+The following parameters (all optional) can be provided in the previous two calls:
+
+* socket_id: Specify the socket where the memory for the device is going to be allocated
+ (by default, socket_id will be the socket where the core that is creating the PMD is running on).
+
+* max_nb_queue_pairs: Specify the maximum number of queue pairs in the device (8 by default).
+
+* max_nb_sessions: Specify the maximum number of sessions that can be created (2048 by default).
+
+Example:
+
+.. code-block:: console
+
+ ./l2fwd-crypto -c 40 -n 4 --vdev="crypto_zuc,socket_id=1,max_nb_sessions=128"
