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.
120 Running the Application
121 -----------------------
123 The application has a number of command line options::
126 ./<build_dir>/examples/dpdk-ipsec-secgw [EAL options] --
127 -p PORTMASK -P -u PORTMASK -j FRAMESIZE
128 -l -w REPLAY_WINDOW_SIZE -e -a
130 -s NUMBER_OF_MBUFS_IN_PACKET_POOL
132 --config (port,queue,lcore)[,(port,queue,lcore)]
134 --cryptodev_mask MASK
136 --event-schedule-type TYPE
141 --frag-ttl FRAG_TTL_NS
145 * ``-p PORTMASK``: Hexadecimal bitmask of ports to configure.
147 * ``-P``: *optional*. Sets all ports to promiscuous mode so that packets are
148 accepted regardless of the packet's Ethernet MAC destination address.
149 Without this option, only packets with the Ethernet MAC destination address
150 set to the Ethernet address of the port are accepted (default is enabled).
152 * ``-u PORTMASK``: hexadecimal bitmask of unprotected ports
154 * ``-j FRAMESIZE``: *optional*. data buffer size (in bytes),
155 in other words maximum data size for one segment.
156 Packets with length bigger then FRAMESIZE still can be received,
157 but will be segmented.
158 Default value: RTE_MBUF_DEFAULT_BUF_SIZE (2176)
159 Minimum value: RTE_MBUF_DEFAULT_BUF_SIZE (2176)
160 Maximum value: UINT16_MAX (65535).
162 * ``-l``: enables code-path that uses librte_ipsec.
164 * ``-w REPLAY_WINDOW_SIZE``: specifies the IPsec sequence number replay window
165 size for each Security Association (available only with librte_ipsec
168 * ``-e``: enables Security Association extended sequence number processing
169 (available only with librte_ipsec code path).
171 * ``-a``: enables Security Association sequence number atomic behavior
172 (available only with librte_ipsec code path).
174 * ``-c``: specifies the SAD cache size. Stores the most recent SA in a per
175 lcore cache. Cache represents flat array containing SA's indexed by SPI.
176 Zero value disables cache.
179 * ``-s``: sets number of mbufs in packet pool, if not provided number of mbufs
180 will be calculated based on number of cores, eth ports and crypto queues.
182 * ``-f CONFIG_FILE_PATH``: the full path of text-based file containing all
183 configuration items for running the application (See Configuration file
184 syntax section below). ``-f CONFIG_FILE_PATH`` **must** be specified.
185 **ONLY** the UNIX format configuration file is accepted.
187 * ``--config (port,queue,lcore)[,(port,queue,lcore)]``: in poll mode determines
188 which queues from which ports are mapped to which cores. In event mode this
189 option is not used as packets are dynamically scheduled to cores by HW.
191 * ``--single-sa SAIDX``: in poll mode use a single SA for outbound traffic,
192 bypassing the SP on both Inbound and Outbound. This option is meant for
193 debugging/performance purposes. In event mode selects driver submode, SA index
196 * ``--cryptodev_mask MASK``: hexadecimal bitmask of the crypto devices
199 * ``--transfer-mode MODE``: sets operating mode of the application
200 "poll" : packet transfer via polling (default)
201 "event" : Packet transfer via event device
203 * ``--event-schedule-type TYPE``: queue schedule type, applies only when
204 --transfer-mode is set to event.
205 "ordered" : Ordered (default)
207 "parallel" : Parallel
208 When --event-schedule-type is set as RTE_SCHED_TYPE_ORDERED/ATOMIC, event
209 device will ensure the ordering. Ordering will be lost when tried in PARALLEL.
211 * ``--rxoffload MASK``: RX HW offload capabilities to enable/use on this port
212 (bitmask of DEV_RX_OFFLOAD_* values). It is an optional parameter and
213 allows user to disable some of the RX HW offload capabilities.
214 By default all HW RX offloads are enabled.
216 * ``--txoffload MASK``: TX HW offload capabilities to enable/use on this port
217 (bitmask of DEV_TX_OFFLOAD_* values). It is an optional parameter and
218 allows user to disable some of the TX HW offload capabilities.
219 By default all HW TX offloads are enabled.
221 * ``--reassemble NUM``: max number of entries in reassemble fragment table.
222 Zero value disables reassembly functionality.
225 * ``--mtu MTU``: MTU value (in bytes) on all attached ethernet ports.
226 Outgoing packets with length bigger then MTU will be fragmented.
227 Incoming packets with length bigger then MTU will be discarded.
230 * ``--frag-ttl FRAG_TTL_NS``: fragment lifetime (in nanoseconds).
231 If packet is not reassembled within this time, received fragments
232 will be discarded. Fragment lifetime should be decreased when
233 there is a high fragmented traffic loss in high bandwidth networks.
234 Should be lower for low number of reassembly buckets.
235 Valid values: from 1 ns to 10 s. Default value: 10000000 (10 s).
238 The mapping of lcores to port/queues is similar to other l3fwd applications.
240 For example, given the following command line to run application in poll mode::
242 ./<build_dir>/examples/dpdk-ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 \
243 --vdev "crypto_null" -- -p 0xf -P -u 0x3 \
244 --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" \
245 -f /path/to/config_file --transfer-mode poll \
247 where each option means:
249 * The ``-l`` option enables cores 20 and 21.
251 * The ``-n`` option sets memory 4 channels.
253 * The ``--socket-mem`` to use 2GB on socket 1.
255 * The ``--vdev "crypto_null"`` option creates virtual NULL cryptodev PMD.
257 * The ``-p`` option enables ports (detected) 0, 1, 2 and 3.
259 * The ``-P`` option enables promiscuous mode.
261 * The ``-u`` option sets ports 0 and 1 as unprotected, leaving 2 and 3 as protected.
263 * The ``--config`` option enables one queue per port with the following mapping:
265 +----------+-----------+-----------+---------------------------------------+
266 | **Port** | **Queue** | **lcore** | **Description** |
268 +----------+-----------+-----------+---------------------------------------+
269 | 0 | 0 | 20 | Map queue 0 from port 0 to lcore 20. |
271 +----------+-----------+-----------+---------------------------------------+
272 | 1 | 0 | 20 | Map queue 0 from port 1 to lcore 20. |
274 +----------+-----------+-----------+---------------------------------------+
275 | 2 | 0 | 21 | Map queue 0 from port 2 to lcore 21. |
277 +----------+-----------+-----------+---------------------------------------+
278 | 3 | 0 | 21 | Map queue 0 from port 3 to lcore 21. |
280 +----------+-----------+-----------+---------------------------------------+
282 * The ``-f /path/to/config_file`` option enables the application read and
283 parse the configuration file specified, and configures the application
284 with a given set of SP, SA and Routing entries accordingly. The syntax of
285 the configuration file will be explained below in more detail. Please
286 **note** the parser only accepts UNIX format text file. Other formats
287 such as DOS/MAC format will cause a parse error.
289 * The ``--transfer-mode`` option selects poll mode for processing packets.
291 Similarly for example, given the following command line to run application in
294 ./<build_dir>/examples/dpdk-ipsec-secgw -c 0x3 -- -P -p 0x3 -u 0x1 \
295 -f /path/to/config_file --transfer-mode event \
296 --event-schedule-type parallel \
298 where each option means:
300 * The ``-c`` option selects cores 0 and 1 to run on.
302 * The ``-P`` option enables promiscuous mode.
304 * The ``-p`` option enables ports (detected) 0 and 1.
306 * The ``-u`` option sets ports 0 as unprotected, leaving 1 as protected.
308 * The ``-f /path/to/config_file`` option has the same behavior as in poll
311 * The ``--transfer-mode`` option selects event mode for processing packets.
313 * The ``--event-schedule-type`` option selects parallel ordering of event queues.
316 Refer to the *DPDK Getting Started Guide* for general information on running
317 applications and the Environment Abstraction Layer (EAL) options.
319 The application would do a best effort to "map" crypto devices to cores, with
320 hardware devices having priority. Basically, hardware devices if present would
321 be assigned to a core before software ones.
322 This means that if the application is using a single core and both hardware
323 and software crypto devices are detected, hardware devices will be used.
325 A way to achieve the case where you want to force the use of virtual crypto
326 devices is to only use the Ethernet devices needed (via the allow flag)
327 and therefore implicitly blocking all hardware crypto devices.
329 For example, something like the following command line:
331 .. code-block:: console
333 ./<build_dir>/examples/dpdk-ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 \
334 -a 81:00.0 -a 81:00.1 -a 81:00.2 -a 81:00.3 \
335 --vdev "crypto_aesni_mb" --vdev "crypto_null" \
337 -p 0xf -P -u 0x3 --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" \
344 The following sections provide the syntax of configurations to initialize
345 your SP, SA, Routing, Flow and Neighbour tables.
346 Configurations shall be specified in the configuration file to be passed to
347 the application. The file is then parsed by the application. The successful
348 parsing will result in the appropriate rules being applied to the tables
352 Configuration File Syntax
353 ~~~~~~~~~~~~~~~~~~~~~~~~~
355 As mention in the overview, the Security Policies are ACL rules.
356 The application parsers the rules specified in the configuration file and
357 passes them to the ACL table, and replicates them per socket in use.
359 Following are the configuration file syntax.
364 The parse treats one line in the configuration file as one configuration
365 item (unless the line concatenation symbol exists). Every configuration
366 item shall follow the syntax of either SP, SA, Routing, Flow or Neighbour
367 rules specified below.
369 The configuration parser supports the following special symbols:
371 * Comment symbol **#**. Any character from this symbol to the end of
372 line is treated as comment and will not be parsed.
374 * Line concatenation symbol **\\**. This symbol shall be placed in the end
375 of the line to be concatenated to the line below. Multiple lines'
376 concatenation is supported.
382 The SP rule syntax is shown as follows:
384 .. code-block:: console

758 The Routing rule syntax is shown as follows:
760 .. code-block:: console
762 rt <ip_ver> <src_ip> <dst_ip> <port>
765 where each options means:
769 * IP protocol version
775 * *ipv4*: IP protocol version 4
776 * *ipv6*: IP protocol version 6
780 * The source IP address and mask
782 * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
786 * *src X.X.X.X/Y* for IPv4
787 * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
791 * The destination IP address and mask
793 * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
797 * *dst X.X.X.X/Y* for IPv4
798 * *dst XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
802 * The traffic output port id
804 * Optional: yes, default output port 0 will be used
810 .. code-block:: console
812 rt ipv4 dst 172.16.1.5/32 port 0
814 rt ipv6 dst 1111:1111:1111:1111:1111:1111:1111:5555/116 port 0
819 Flow rule enables the usage of hardware classification capabilities to match specific
820 ingress traffic and redirect the packets to the specified queue. This feature is
821 optional and relies on hardware ``rte_flow`` support.
823 The flow rule syntax is shown as follows:
825 .. code-block:: console
827 flow <ip_ver> <src_ip> <dst_ip> <port> <queue>
830 where each options means:
834 * IP protocol version
840 * *ipv4*: IP protocol version 4
841 * *ipv6*: IP protocol version 6
845 * The source IP address and mask
847 * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
851 * *src X.X.X.X/Y* for IPv4
852 * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
856 * The destination IP address and mask
858 * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
862 * *dst X.X.X.X/Y* for IPv4
863 * *dst XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
867 * The traffic input port id
869 * Optional: yes, default input port 0 will be used
875 * The traffic input queue id
877 * Optional: yes, default input queue 0 will be used
883 .. code-block:: console
885 flow ipv4 dst 172.16.1.5/32 port 0 queue 0
887 flow ipv6 dst 1111:1111:1111:1111:1111:1111:1111:5555/116 port 1 queue 0
890 Neighbour rule syntax
891 ^^^^^^^^^^^^^^^^^^^^^
893 The Neighbour rule syntax is shown as follows:
895 .. code-block:: console
897 neigh <port> <dst_mac>
900 where each options means:
912 * The destination ethernet address to use for that port
920 Example Neighbour rules:
922 .. code-block:: console
924 neigh port 0 DE:AD:BE:EF:01:02
929 The test directory contains scripts for testing the various encryption
932 The purpose of the scripts is to automate ipsec-secgw testing
933 using another system running linux as a DUT.
935 The user must setup the following environment variables:
937 * ``SGW_PATH``: path to the ipsec-secgw binary to test.
939 * ``REMOTE_HOST``: IP address/hostname of the DUT.
941 * ``REMOTE_IFACE``: interface name for the test-port on the DUT.
943 * ``ETH_DEV``: ethernet device to be used on the SUT by DPDK ('-a <pci-id>')
945 Also the user can optionally setup:
947 * ``SGW_LCORE``: lcore to run ipsec-secgw on (default value is 0)
949 * ``CRYPTO_DEV``: crypto device to be used ('-a <pci-id>'). If none specified
950 appropriate vdevs will be created by the script
952 Scripts can be used for multiple test scenarios. To check all available
955 .. code-block:: console
957 /bin/bash run_test.sh -h
959 Note that most of the tests require the appropriate crypto PMD/device to be
965 Two servers are required for the tests, SUT and DUT.
967 Make sure the user from the SUT can ssh to the DUT without entering the password.
968 To enable this feature keys must be setup on the DUT.
970 ``ssh-keygen`` will make a private & public key pair on the SUT.
972 ``ssh-copy-id`` <user name>@<target host name> on the SUT will copy the public
973 key to the DUT. It will ask for credentials so that it can upload the public key.
975 The SUT and DUT are connected through at least 2 NIC ports.
977 One NIC port is expected to be managed by linux on both machines and will be
978 used as a control path.
980 The second NIC port (test-port) should be bound to DPDK on the SUT, and should
981 be managed by linux on the DUT.
983 The script starts ``ipsec-secgw`` with 2 NIC devices: ``test-port`` and
986 It then configures the local tap interface and the remote interface and IPsec
987 policies in the following way:
989 Traffic going over the test-port in both directions has to be protected by IPsec.
991 Traffic going over the TAP port in both directions does not have to be protected.
995 DUT OS(NIC1)--(IPsec)-->(NIC1)ipsec-secgw(TAP)--(plain)-->(TAP)SUT OS
997 SUT OS(TAP)--(plain)-->(TAP)psec-secgw(NIC1)--(IPsec)-->(NIC1)DUT OS
999 It then tries to perform some data transfer using the scheme described above.
1004 In the ipsec-secgw/test directory run
1006 /bin/bash run_test.sh <options> <ipsec_mode>
1010 * ``-4`` Perform tests with use of IPv4. One or both [-46] options needs to be
1013 * ``-6`` Perform tests with use of IPv6. One or both [-46] options needs to be
1016 * ``-m`` Add IPSec tunnel mixed IP version tests - outer IP version different
1017 than inner. Inner IP version will match selected option [-46].
1019 * ``-i`` Run tests in inline mode. Regular tests will not be invoked.
1021 * ``-f`` Run tests for fallback mechanism. Regular tests will not be invoked.
1023 * ``-l`` Run tests in legacy mode only. It cannot be used with options [-fsc].
1024 On default library mode is used.
1026 * ``-s`` Run all tests with reassembly support. On default only tests for
1027 fallback mechanism use reassembly support.
1029 * ``-c`` Run tests with use of cpu-crypto. For inline tests it will not be
1030 applied. On default lookaside-none is used.
1032 * ``-p`` Perform packet validation tests. Option [-46] is not required.
1034 * ``-h`` Show usage.
1036 If <ipsec_mode> is specified, only tests for that mode will be invoked. For the
1037 list of available modes please refer to run_test.sh.
