examples/ipsec-secgw: add IPsec sample application
Sample app implementing an IPsec Security Geteway. The main goal of this app is to show the use of cryptodev framework in a "real world" application. Currently only supported static IPv4 ESP IPsec tunnels for the following algorithms: - Cipher: AES-CBC, NULL - Authentication: HMAC-SHA1, NULL Not supported: - SA auto negotiation (No IKE implementation) - chained mbufs Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com> Acked-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>

+
+IPsec Security Gateway Sample Application
+=========================================
+
+The IPsec Security Gateway application is an example of a "real world"
+application using DPDK cryptodev framework.
+
+Overview
+--------
+
+The application demonstrates the implementation of a Security Gateway
+(not IPsec compliant, see Constraints bellow) using DPDK based on RFC4301,
+RFC4303, RFC3602 and RFC2404.
+
+Internet Key Exchange (IKE) is not implemented, so only manual setting of
+Security Policies and Security Associations is supported.
+
+The Security Policies (SP) are implemented as ACL rules, the Security
+Associations (SA) are stored in a table and the Routing is implemented
+using LPM.
+
+The application classify the ports between Protected and Unprotected.
+Thus, traffic received in an Unprotected or Protected port is consider
+Inbound or Outbound respectively.
+
+Path for IPsec Inbound traffic:
+
+* Read packets from the port
+* Classify packets between IPv4 and ESP.
+* Inbound SA lookup for ESP packets based on their SPI
+* Verification/Decryption
+* Removal of ESP and outer IP header
+* Inbound SP check using ACL of decrypted packets and any other IPv4 packet
+ we read.
+* Routing
+* Write packet to port
+
+Path for IPsec Outbound traffic:
+
+* Read packets from the port
+* Outbound SP check using ACL of all IPv4 traffic
+* Outbound SA lookup for packets that need IPsec protection
+* Add ESP and outter IP header
+* Encryption/Digest
+* Routing
+* Write packet to port
+
+Constraints
+-----------
+* IPv4 traffic
+* ESP tunnel mode
+* EAS-CBC, HMAC-SHA1 and NULL
+* Each SA must be handle by a unique lcore (1 RX queue per port)
+* No chained mbufs
+
+Compiling the Application
+-------------------------
+
+To compile the application:
+
+#. Go to the sample application directory:
+
+ .. code-block:: console
+
+ export RTE_SDK=/path/to/rte_sdk
+ cd ${RTE_SDK}/examples/ipsec-secgw
+
+#. Set the target (a default target is used if not specified). For example:
+
+ .. code-block:: console
+
+ export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+ See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+
+#. Build the application:
+
+ .. code-block:: console
+
+ make
+
+Running the Application
+-----------------------
+
+The application has a number of command line options:
+
+.. code-block:: console
+
+ ./build/ipsec-secgw [EAL options] -- -p PORTMASK -P -u PORTMASK --config
+ (port,queue,lcore)[,(port,queue,lcore] --single-sa SAIDX --ep0|--ep1
+
+where,
+
+* -p PORTMASK: Hexadecimal bitmask of ports to configure
+
+* -P: optional, sets all ports to promiscuous mode so that packets are
+ accepted regardless of the packet's Ethernet MAC destination address.
+ Without this option, only packets with the Ethernet MAC destination address
+ set to the Ethernet address of the port are accepted (default is enabled).
+
+* -u PORTMASK: hexadecimal bitmask of unprotected ports
+
+* --config (port,queue,lcore)[,(port,queue,lcore)]: determines which queues
+ from which ports are mapped to which cores
+
+* --single-sa SAIDX: use a single SA for outbound traffic, bypassing the SP
+ on both Inbound and Outbound. This option is meant for debugging/performance
+ purposes.
+
+* --ep0: configure the app as Endpoint 0.
+
+* --ep1: configure the app as Endpoint 1.
+
+Either one of --ep0 or --ep1 *must* be specified.
+The main purpose of these options is two easily configure two systems
+back-to-back that would forward traffic through an IPsec tunnel.
+
+The mapping of lcores to port/queues is similar to other l3fwd applications.
+
+For example, given the following command line:
+
+.. code-block:: console
+
+ ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048
+ --vdev "cryptodev_null_pmd" -- -p 0xf -P -u 0x3
+ --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" --ep0
+
+where each options means:
+
+* The -l option enables cores 20 and 21
+
+* The -n option sets memory 4 channels
+
+* The --socket-mem to use 2GB on socket 1
+
+* The --vdev "cryptodev_null_pmd" option creates virtual NULL cryptodev PMD
+
+* The -p option enables ports (detected) 0, 1, 2 and 3
+
+* The -P option enables promiscuous mode
+
+* The -u option sets ports 1 and 2 as unprotected, leaving 2 and 3 as protected
+
+* The --config option enables one queue per port with the following mapping:
+
++----------+-----------+-----------+---------------------------------------+
+| **Port** | **Queue** | **lcore** | **Description** |
+| | | | |
++----------+-----------+-----------+---------------------------------------+
+| 0 | 0 | 20 | Map queue 0 from port 0 to lcore 20. |
+| | | | |
++----------+-----------+-----------+---------------------------------------+
+| 1 | 0 | 20 | Map queue 0 from port 1 to lcore 20. |
+| | | | |
++----------+-----------+-----------+---------------------------------------+
+| 2 | 0 | 21 | Map queue 0 from port 2 to lcore 21. |
+| | | | |
++----------+-----------+-----------+---------------------------------------+
+| 3 | 0 | 21 | Map queue 0 from port 3 to lcore 21. |
+| | | | |
++----------+-----------+-----------+---------------------------------------+
+
+* The --ep0 options configures the app with a given set of SP, SA and Routing
+ entries as explained below in more detail.
+
+Refer to the *DPDK Getting Started Guide* for general information on running
+applications and the Environment Abstraction Layer (EAL) options.
+
+The application would do a best effort to "map" crypto devices to cores, with
+hardware devices having priority.
+This means that if the application is using a single core and both hardware
+and software crypto devices are detected, hardware devices will be used.
+
+A way to achive the case where you want to force the use of virtual crypto
+devices is to whitelist the ethernet devices needed and therefore implicitely
+blacklisting all hardware crypto devices.
+
+For example, something like the following command line:
+
+.. code-block:: console
+
+ ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048
+ -w 81:00.0 -w 81:00.1 -w 81:00.2 -w 81:00.3
+ --vdev "cryptodev_aesni_mb_pmd" --vdev "cryptodev_null_pmd" --
+ -p 0xf -P -u 0x3 --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)"
+ --ep0
+
+Configurations
+--------------
+
+The following sections provide some details on the default values used to
+initialize the SP, SA and Routing tables.
+Currently all the configuration is hard coded into the application.
+
+Security Policy Initialization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As mention in the overview, the Security Policies are ACL rules.
+The application defines two ACLs, one each of Inbound and Outbound, and
+it replicates them per socket in use.
+
+Following are the default rules:
+

+
+Security Association Initialization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The SAs are kept in a array table.
+
+For Inbound, the SPI is used as index module the table size.
+This means that on a table for 100 SA, SPI 5 and 105 would use the same index
+and that is not currently supported.
+
+Notice that it is not an issue for Outbound traffic as we store the index and
+not the SPI in the Security Policy.
+
+All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
+block size and key, and authentication digest size and key.
+
+Following are the default values:
+
