IPsec Security Gateway Sample Application
=========================================
Thus, traffic received on an Unprotected or Protected port is consider
Inbound or Outbound respectively.
+The application also supports complete IPsec protocol offload to hardware
+(Look aside crypto accelerator or using ethernet device). It also support
+inline ipsec processing by the supported ethernet device during transmission.
+These modes can be selected during the SA creation configuration.
+
+In case of complete protocol offload, the processing of headers(ESP and outer
+IP header) is done by the hardware and the application does not need to
+add/remove them during outbound/inbound processing.
+
+For inline offloaded outbound traffic, the application will not do the LPM
+lookup for routing, as the port on which the packet has to be forwarded will be
+part of the SA. Security parameters will be configured on that port only, and
+sending the packet on other ports could result in unencrypted packets being
+sent out.
+
The Path for IPsec Inbound traffic is:
* Read packets from the port.
* Classify packets between IPv4 and ESP.
* Perform Inbound SA lookup for ESP packets based on their SPI.
-* Perform Verification/Decryption.
-* Remove ESP and outer IP header
+* Perform Verification/Decryption (Not needed in case of inline ipsec).
+* Remove ESP and outer IP header (Not needed in case of protocol offload).
* Inbound SP check using ACL of decrypted packets and any other IPv4 packets.
* Routing.
* Write packet to port.
* Read packets from the port.
* Perform Outbound SP check using ACL of all IPv4 traffic.
* Perform Outbound SA lookup for packets that need IPsec protection.
-* Add ESP and outer IP header.
-* Perform Encryption/Digest.
+* Add ESP and outer IP header (Not needed in case protocol offload).
+* Perform Encryption/Digest (Not needed in case of inline ipsec).
* Routing.
* Write packet to port.
+The application supports two modes of operation: poll mode and event mode.
+
+* In the poll mode a core receives packets from statically configured list
+ of eth ports and eth ports' queues.
+
+* In the event mode a core receives packets as events. After packet processing
+ is done core submits them back as events to an event device. This enables
+ multicore scaling and HW assisted scheduling by making use of the event device
+ capabilities. The event mode configuration is predefined. All packets reaching
+ given eth port will arrive at the same event queue. All event queues are mapped
+ to all event ports. This allows all cores to receive traffic from all ports.
+ Since the underlying event device might have varying capabilities, the worker
+ threads can be drafted differently to maximize performance. For example, if an
+ event device - eth device pair has Tx internal port, then application can call
+ rte_event_eth_tx_adapter_enqueue() instead of regular rte_event_enqueue_burst().
+ So a thread which assumes that the device pair has internal port will not be the
+ right solution for another pair. The infrastructure added for the event mode aims
+ to help application to have multiple worker threads by maximizing performance from
+ every type of event device without affecting existing paths/use cases. The worker
+ to be used will be determined by the operating conditions and the underlying device
+ capabilities. **Currently the application provides non-burst, internal port worker
+ threads and supports inline protocol only.** It also provides infrastructure for
+ non-internal port however does not define any worker threads.
+
+Additionally the event mode introduces two submodes of processing packets:
+
+* Driver submode: This submode has bare minimum changes in the application to support
+ IPsec. There are no lookups, no routing done in the application. And for inline
+ protocol use case, the worker thread resembles l2fwd worker thread as the IPsec
+ processing is done entirely in HW. This mode can be used to benchmark the raw
+ performance of the HW. The driver submode is selected with --single-sa option
+ (used also by poll mode). When --single-sa option is used in conjution with event
+ mode then index passed to --single-sa is ignored.
+
+* App submode: This submode has all the features currently implemented with the
+ application (non librte_ipsec path). All the lookups, routing follows existing
+ methods and report numbers that can be compared against regular poll mode
+ benchmark numbers.
Constraints

Compiling the Application
-------------------------
-To compile the application:
-
-#. Go to the sample application directory::
-
- 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::
-
-
- export RTE_TARGET=x86_64-native-linuxapp-gcc
-
- See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
+To compile the sample application see :doc:`compiling`.
-#. Build the application::
-
- make
+The application is located in the ``ipsec-secgw`` sub-directory.

+
+Test directory
+--------------
+
+The test directory contains scripts for testing the various encryption
+algorithms.
+
+The purpose of the scripts is to automate ipsec-secgw testing
+using another system running linux as a DUT.
+
+The user must setup the following environment variables:
+
+* ``SGW_PATH``: path to the ipsec-secgw binary to test.
+
+* ``REMOTE_HOST``: IP address/hostname of the DUT.
+
+* ``REMOTE_IFACE``: interface name for the test-port on the DUT.
+
+* ``ETH_DEV``: ethernet device to be used on the SUT by DPDK ('-w <pci-id>')
+
+Also the user can optionally setup:
+
+* ``SGW_LCORE``: lcore to run ipsec-secgw on (default value is 0)
+
+* ``CRYPTO_DEV``: crypto device to be used ('-w <pci-id>'). If none specified
+ appropriate vdevs will be created by the script
+
+* ``MULTI_SEG_TEST``: ipsec-secgw option to enable reassembly support and
+ specify size of reassembly table (e.g.
+ ``MULTI_SEG_TEST='--reassemble 128'``). This option must be set for
+ fallback session tests.
+
+Note that most of the tests require the appropriate crypto PMD/device to be
+available.
+
+Server configuration
+~~~~~~~~~~~~~~~~~~~~
+
+Two servers are required for the tests, SUT and DUT.
+
+Make sure the user from the SUT can ssh to the DUT without entering the password.
+To enable this feature keys must be setup on the DUT.
+
+``ssh-keygen`` will make a private & public key pair on the SUT.
+
+``ssh-copy-id`` <user name>@<target host name> on the SUT will copy the public
+key to the DUT. It will ask for credentials so that it can upload the public key.
+
+The SUT and DUT are connected through at least 2 NIC ports.
+
+One NIC port is expected to be managed by linux on both machines and will be
+used as a control path.
+
+The second NIC port (test-port) should be bound to DPDK on the SUT, and should
+be managed by linux on the DUT.
+
+The script starts ``ipsec-secgw`` with 2 NIC devices: ``test-port`` and
+``tap vdev``.
+
+It then configures the local tap interface and the remote interface and IPsec
+policies in the following way:
+
+Traffic going over the test-port in both directions has to be protected by IPsec.
+
+Traffic going over the TAP port in both directions does not have to be protected.
+
+i.e:
+
+DUT OS(NIC1)--(IPsec)-->(NIC1)ipsec-secgw(TAP)--(plain)-->(TAP)SUT OS
+
+SUT OS(TAP)--(plain)-->(TAP)psec-secgw(NIC1)--(IPsec)-->(NIC1)DUT OS
+
+It then tries to perform some data transfer using the scheme described above.
