5 IPsec Security Gateway Sample Application
6 =========================================
8 The IPsec Security Gateway application is an example of a "real world"
9 application using DPDK cryptodev framework.
14 The application demonstrates the implementation of a Security Gateway
15 (not IPsec compliant, see the Constraints section below) using DPDK based on RFC4301,
16 RFC4303, RFC3602 and RFC2404.
18 Internet Key Exchange (IKE) is not implemented, so only manual setting of
19 Security Policies and Security Associations is supported.
21 The Security Policies (SP) are implemented as ACL rules, the Security
22 Associations (SA) are stored in a table and the routing is implemented
25 The application classifies the ports as *Protected* and *Unprotected*.
26 Thus, traffic received on an Unprotected or Protected port is consider
27 Inbound or Outbound respectively.
29 The application also supports complete IPsec protocol offload to hardware
30 (Look aside crypto accelerator or using ethernet device). It also support
31 inline ipsec processing by the supported ethernet device during transmission.
32 These modes can be selected during the SA creation configuration.
34 In case of complete protocol offload, the processing of headers(ESP and outer
35 IP header) is done by the hardware and the application does not need to
36 add/remove them during outbound/inbound processing.
38 For inline offloaded outbound traffic, the application will not do the LPM
39 lookup for routing, as the port on which the packet has to be forwarded will be
40 part of the SA. Security parameters will be configured on that port only, and
41 sending the packet on other ports could result in unencrypted packets being
44 The Path for IPsec Inbound traffic is:
46 * Read packets from the port.
47 * Classify packets between IPv4 and ESP.
48 * Perform Inbound SA lookup for ESP packets based on their SPI.
49 * Perform Verification/Decryption (Not needed in case of inline ipsec).
50 * Remove ESP and outer IP header (Not needed in case of protocol offload).
51 * Inbound SP check using ACL of decrypted packets and any other IPv4 packets.
53 * Write packet to port.
55 The Path for the IPsec Outbound traffic is:
57 * Read packets from the port.
58 * Perform Outbound SP check using ACL of all IPv4 traffic.
59 * Perform Outbound SA lookup for packets that need IPsec protection.
60 * Add ESP and outer IP header (Not needed in case protocol offload).
61 * Perform Encryption/Digest (Not needed in case of inline ipsec).
63 * Write packet to port.
65 The application supports two modes of operation: poll mode and event mode.
67 * In the poll mode a core receives packets from statically configured list
68 of eth ports and eth ports' queues.
70 * In the event mode a core receives packets as events. After packet processing
71 is done core submits them back as events to an event device. This enables
72 multicore scaling and HW assisted scheduling by making use of the event device
73 capabilities. The event mode configuration is predefined. All packets reaching
74 given eth port will arrive at the same event queue. All event queues are mapped
75 to all event ports. This allows all cores to receive traffic from all ports.
76 Since the underlying event device might have varying capabilities, the worker
77 threads can be drafted differently to maximize performance. For example, if an
78 event device - eth device pair has Tx internal port, then application can call
79 rte_event_eth_tx_adapter_enqueue() instead of regular rte_event_enqueue_burst().
80 So a thread which assumes that the device pair has internal port will not be the
81 right solution for another pair. The infrastructure added for the event mode aims
82 to help application to have multiple worker threads by maximizing performance from
83 every type of event device without affecting existing paths/use cases. The worker
84 to be used will be determined by the operating conditions and the underlying device
85 capabilities. **Currently the application provides non-burst, internal port worker
86 threads and supports inline protocol only.** It also provides infrastructure for
87 non-internal port however does not define any worker threads.
89 Additionally the event mode introduces two submodes of processing packets:
91 * Driver submode: This submode has bare minimum changes in the application to support
92 IPsec. There are no lookups, no routing done in the application. And for inline
93 protocol use case, the worker thread resembles l2fwd worker thread as the IPsec
94 processing is done entirely in HW. This mode can be used to benchmark the raw
95 performance of the HW. The driver submode is selected with --single-sa option
96 (used also by poll mode). When --single-sa option is used in conjution with event
97 mode then index passed to --single-sa is ignored.
99 * App submode: This submode has all the features currently implemented with the
100 application (non librte_ipsec path). All the lookups, routing follows existing
101 methods and report numbers that can be compared against regular poll mode
107 * No IPv6 options headers.
109 * Supported algorithms: AES-CBC, AES-CTR, AES-GCM, 3DES-CBC, HMAC-SHA1 and NULL.
110 * Each SA must be handle by a unique lcore (*1 RX queue per port*).
112 Compiling the Application
113 -------------------------
115 To compile the sample application see :doc:`compiling`.
117 The application is located in the ``ipsec-secgw`` sub-directory.
119 #. [Optional] Build the application for debugging:
120 This option adds some extra flags, disables compiler optimizations and
126 Running the Application
127 -----------------------
129 The application has a number of command line options::
132 ./build/ipsec-secgw [EAL options] --
133 -p PORTMASK -P -u PORTMASK -j FRAMESIZE
134 -l -w REPLAY_WINOW_SIZE -e -a
136 -s NUMBER_OF_MBUFS_IN_PACKET_POOL
138 --config (port,queue,lcore)[,(port,queue,lcore)]
140 --cryptodev_mask MASK
142 --event-schedule-type TYPE
147 --frag-ttl FRAG_TTL_NS
151 * ``-p PORTMASK``: Hexadecimal bitmask of ports to configure.
153 * ``-P``: *optional*. Sets all ports to promiscuous mode so that packets are
154 accepted regardless of the packet's Ethernet MAC destination address.
155 Without this option, only packets with the Ethernet MAC destination address
156 set to the Ethernet address of the port are accepted (default is enabled).
158 * ``-u PORTMASK``: hexadecimal bitmask of unprotected ports
160 * ``-j FRAMESIZE``: *optional*. data buffer size (in bytes),
161 in other words maximum data size for one segment.
162 Packets with length bigger then FRAMESIZE still can be received,
163 but will be segmented.
164 Default value: RTE_MBUF_DEFAULT_BUF_SIZE (2176)
165 Minimum value: RTE_MBUF_DEFAULT_BUF_SIZE (2176)
166 Maximum value: UINT16_MAX (65535).
168 * ``-l``: enables code-path that uses librte_ipsec.
170 * ``-w REPLAY_WINOW_SIZE``: specifies the IPsec sequence number replay window
171 size for each Security Association (available only with librte_ipsec
174 * ``-e``: enables Security Association extended sequence number processing
175 (available only with librte_ipsec code path).
177 * ``-a``: enables Security Association sequence number atomic behavior
178 (available only with librte_ipsec code path).
180 * ``-c``: specifies the SAD cache size. Stores the most recent SA in a per
181 lcore cache. Cache represents flat array containing SA's indexed by SPI.
182 Zero value disables cache.
185 * ``-s``: sets number of mbufs in packet pool, if not provided number of mbufs
186 will be calculated based on number of cores, eth ports and crypto queues.
188 * ``-f CONFIG_FILE_PATH``: the full path of text-based file containing all
189 configuration items for running the application (See Configuration file
190 syntax section below). ``-f CONFIG_FILE_PATH`` **must** be specified.
191 **ONLY** the UNIX format configuration file is accepted.
193 * ``--config (port,queue,lcore)[,(port,queue,lcore)]``: in poll mode determines
194 which queues from which ports are mapped to which cores. In event mode this
195 option is not used as packets are dynamically scheduled to cores by HW.
197 * ``--single-sa SAIDX``: in poll mode use a single SA for outbound traffic,
198 bypassing the SP on both Inbound and Outbound. This option is meant for
199 debugging/performance purposes. In event mode selects driver submode, SA index
202 * ``--cryptodev_mask MASK``: hexadecimal bitmask of the crypto devices
205 * ``--transfer-mode MODE``: sets operating mode of the application
206 "poll" : packet transfer via polling (default)
207 "event" : Packet transfer via event device
209 * ``--event-schedule-type TYPE``: queue schedule type, applies only when
210 --transfer-mode is set to event.
211 "ordered" : Ordered (default)
213 "parallel" : Parallel
214 When --event-schedule-type is set as RTE_SCHED_TYPE_ORDERED/ATOMIC, event
215 device will ensure the ordering. Ordering will be lost when tried in PARALLEL.
217 * ``--rxoffload MASK``: RX HW offload capabilities to enable/use on this port
218 (bitmask of DEV_RX_OFFLOAD_* values). It is an optional parameter and
219 allows user to disable some of the RX HW offload capabilities.
220 By default all HW RX offloads are enabled.
222 * ``--txoffload MASK``: TX HW offload capabilities to enable/use on this port
223 (bitmask of DEV_TX_OFFLOAD_* values). It is an optional parameter and
224 allows user to disable some of the TX HW offload capabilities.
225 By default all HW TX offloads are enabled.
227 * ``--reassemble NUM``: max number of entries in reassemble fragment table.
228 Zero value disables reassembly functionality.
231 * ``--mtu MTU``: MTU value (in bytes) on all attached ethernet ports.
232 Outgoing packets with length bigger then MTU will be fragmented.
233 Incoming packets with length bigger then MTU will be discarded.
236 * ``--frag-ttl FRAG_TTL_NS``: fragment lifetime (in nanoseconds).
237 If packet is not reassembled within this time, received fragments
238 will be discarded. Fragment lifetime should be decreased when
239 there is a high fragmented traffic loss in high bandwidth networks.
240 Should be lower for low number of reassembly buckets.
241 Valid values: from 1 ns to 10 s. Default value: 10000000 (10 s).
244 The mapping of lcores to port/queues is similar to other l3fwd applications.
246 For example, given the following command line to run application in poll mode::
248 ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 \
249 --vdev "crypto_null" -- -p 0xf -P -u 0x3 \
250 --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" \
251 -f /path/to/config_file --transfer-mode poll \
253 where each option means:
255 * The ``-l`` option enables cores 20 and 21.
257 * The ``-n`` option sets memory 4 channels.
259 * The ``--socket-mem`` to use 2GB on socket 1.
261 * The ``--vdev "crypto_null"`` option creates virtual NULL cryptodev PMD.
263 * The ``-p`` option enables ports (detected) 0, 1, 2 and 3.
265 * The ``-P`` option enables promiscuous mode.
267 * The ``-u`` option sets ports 0 and 1 as unprotected, leaving 2 and 3 as protected.
269 * The ``--config`` option enables one queue per port with the following mapping:
271 +----------+-----------+-----------+---------------------------------------+
272 | **Port** | **Queue** | **lcore** | **Description** |
274 +----------+-----------+-----------+---------------------------------------+
275 | 0 | 0 | 20 | Map queue 0 from port 0 to lcore 20. |
277 +----------+-----------+-----------+---------------------------------------+
278 | 1 | 0 | 20 | Map queue 0 from port 1 to lcore 20. |
280 +----------+-----------+-----------+---------------------------------------+
281 | 2 | 0 | 21 | Map queue 0 from port 2 to lcore 21. |
283 +----------+-----------+-----------+---------------------------------------+
284 | 3 | 0 | 21 | Map queue 0 from port 3 to lcore 21. |
286 +----------+-----------+-----------+---------------------------------------+
288 * The ``-f /path/to/config_file`` option enables the application read and
289 parse the configuration file specified, and configures the application
290 with a given set of SP, SA and Routing entries accordingly. The syntax of
291 the configuration file will be explained below in more detail. Please
292 **note** the parser only accepts UNIX format text file. Other formats
293 such as DOS/MAC format will cause a parse error.
295 * The ``--transfer-mode`` option selects poll mode for processing packets.
297 Similarly for example, given the following command line to run application in
300 ./build/ipsec-secgw -c 0x3 -- -P -p 0x3 -u 0x1 \
301 -f /path/to/config_file --transfer-mode event \
302 --event-schedule-type parallel \
304 where each option means:
306 * The ``-c`` option selects cores 0 and 1 to run on.
308 * The ``-P`` option enables promiscuous mode.
310 * The ``-p`` option enables ports (detected) 0 and 1.
312 * The ``-u`` option sets ports 0 as unprotected, leaving 1 as protected.
314 * The ``-f /path/to/config_file`` option has the same behavior as in poll
317 * The ``--transfer-mode`` option selects event mode for processing packets.
319 * The ``--event-schedule-type`` option selects parallel ordering of event queues.
322 Refer to the *DPDK Getting Started Guide* for general information on running
323 applications and the Environment Abstraction Layer (EAL) options.
325 The application would do a best effort to "map" crypto devices to cores, with
326 hardware devices having priority. Basically, hardware devices if present would
327 be assigned to a core before software ones.
328 This means that if the application is using a single core and both hardware
329 and software crypto devices are detected, hardware devices will be used.
331 A way to achieve the case where you want to force the use of virtual crypto
332 devices is to whitelist the Ethernet devices needed and therefore implicitly
333 blacklisting all hardware crypto devices.
335 For example, something like the following command line:
337 .. code-block:: console
339 ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 \
340 -w 81:00.0 -w 81:00.1 -w 81:00.2 -w 81:00.3 \
341 --vdev "crypto_aesni_mb" --vdev "crypto_null" \
343 -p 0xf -P -u 0x3 --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" \
350 The following sections provide the syntax of configurations to initialize
351 your SP, SA, Routing and Neighbour tables.
352 Configurations shall be specified in the configuration file to be passed to
353 the application. The file is then parsed by the application. The successful
354 parsing will result in the appropriate rules being applied to the tables
358 Configuration File Syntax
359 ~~~~~~~~~~~~~~~~~~~~~~~~~
361 As mention in the overview, the Security Policies are ACL rules.
362 The application parsers the rules specified in the configuration file and
363 passes them to the ACL table, and replicates them per socket in use.
365 Following are the configuration file syntax.
370 The parse treats one line in the configuration file as one configuration
371 item (unless the line concatenation symbol exists). Every configuration
372 item shall follow the syntax of either SP, SA, Routing or Neighbour
373 rules specified below.
375 The configuration parser supports the following special symbols:
377 * Comment symbol **#**. Any character from this symbol to the end of
378 line is treated as comment and will not be parsed.
380 * Line concatenation symbol **\\**. This symbol shall be placed in the end
381 of the line to be concatenated to the line below. Multiple lines'
382 concatenation is supported.
388 The SP rule syntax is shown as follows:
390 .. code-block:: console

753 The Routing rule syntax is shown as follows:
755 .. code-block:: console
757 rt <ip_ver> <src_ip> <dst_ip> <port>
760 where each options means:
764 * IP protocol version
770 * *ipv4*: IP protocol version 4
771 * *ipv6*: IP protocol version 6
775 * The source IP address and mask
777 * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
781 * *src X.X.X.X/Y* for IPv4
782 * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
786 * The destination IP address and mask
788 * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
792 * *dst X.X.X.X/Y* for IPv4
793 * *dst XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
797 * The traffic output port id
799 * Optional: yes, default output port 0 will be used
805 .. code-block:: console
807 rt ipv4 dst 172.16.1.5/32 port 0
809 rt ipv6 dst 1111:1111:1111:1111:1111:1111:1111:5555/116 port 0
811 Neighbour rule syntax
812 ^^^^^^^^^^^^^^^^^^^^^
814 The Neighbour rule syntax is shown as follows:
816 .. code-block:: console
818 neigh <port> <dst_mac>
821 where each options means:
833 * The destination ethernet address to use for that port
841 Example Neighbour rules:
843 .. code-block:: console
845 neigh port 0 DE:AD:BE:EF:01:02
850 The test directory contains scripts for testing the various encryption
853 The purpose of the scripts is to automate ipsec-secgw testing
854 using another system running linux as a DUT.
856 The user must setup the following environment variables:
858 * ``SGW_PATH``: path to the ipsec-secgw binary to test.
860 * ``REMOTE_HOST``: IP address/hostname of the DUT.
862 * ``REMOTE_IFACE``: interface name for the test-port on the DUT.
864 * ``ETH_DEV``: ethernet device to be used on the SUT by DPDK ('-w <pci-id>')
866 Also the user can optionally setup:
868 * ``SGW_LCORE``: lcore to run ipsec-secgw on (default value is 0)
870 * ``CRYPTO_DEV``: crypto device to be used ('-w <pci-id>'). If none specified
871 appropriate vdevs will be created by the script
873 Scripts can be used for multiple test scenarios. To check all available
876 .. code-block:: console
878 /bin/bash run_test.sh -h
880 Note that most of the tests require the appropriate crypto PMD/device to be
886 Two servers are required for the tests, SUT and DUT.
888 Make sure the user from the SUT can ssh to the DUT without entering the password.
889 To enable this feature keys must be setup on the DUT.
891 ``ssh-keygen`` will make a private & public key pair on the SUT.
893 ``ssh-copy-id`` <user name>@<target host name> on the SUT will copy the public
894 key to the DUT. It will ask for credentials so that it can upload the public key.
896 The SUT and DUT are connected through at least 2 NIC ports.
898 One NIC port is expected to be managed by linux on both machines and will be
899 used as a control path.
901 The second NIC port (test-port) should be bound to DPDK on the SUT, and should
902 be managed by linux on the DUT.
904 The script starts ``ipsec-secgw`` with 2 NIC devices: ``test-port`` and
907 It then configures the local tap interface and the remote interface and IPsec
908 policies in the following way:
910 Traffic going over the test-port in both directions has to be protected by IPsec.
912 Traffic going over the TAP port in both directions does not have to be protected.
916 DUT OS(NIC1)--(IPsec)-->(NIC1)ipsec-secgw(TAP)--(plain)-->(TAP)SUT OS
918 SUT OS(TAP)--(plain)-->(TAP)psec-secgw(NIC1)--(IPsec)-->(NIC1)DUT OS
920 It then tries to perform some data transfer using the scheme described above.
925 In the ipsec-secgw/test directory run
927 /bin/bash run_test.sh <options> <ipsec_mode>
931 * ``-4`` Perform tests with use of IPv4. One or both [-46] options needs to be
934 * ``-6`` Perform tests with use of IPv6. One or both [-46] options needs to be
937 * ``-m`` Add IPSec tunnel mixed IP version tests - outer IP version different
938 than inner. Inner IP version will match selected option [-46].
940 * ``-i`` Run tests in inline mode. Regular tests will not be invoked.
942 * ``-f`` Run tests for fallback mechanism. Regular tests will not be invoked.
944 * ``-l`` Run tests in legacy mode only. It cannot be used with options [-fsc].
945 On default library mode is used.
947 * ``-s`` Run all tests with reassembly support. On default only tests for
948 fallback mechanism use reassembly support.
950 * ``-c`` Run tests with use of cpu-crypto. For inline tests it will not be
951 applied. On default lookaside-none is used.
953 * ``-p`` Perform packet validation tests. Option [-46] is not required.
957 If <ipsec_mode> is specified, only tests for that mode will be invoked. For the
958 list of available modes please refer to run_test.sh.
