2019-02-07IPSEC: no second lookup after tunnel encapNeale Ranns1-76/+71
in the same maaner as with other tunnel tyeps we use the FIB to cache and track the destination used to reach the tunnel endpoint. Post encap we can then ship the packet straight to this adjacency and thus elide the costly second lookup. - SA add and del function so they can be used both directly from the API and for tunnels. - API change for the SA dump to use the SA type - ipsec_key_t type for convenience (copying, [un]formating) - no matching tunnel counters in ipsec-if-input Change-Id: I9d144a59667f7bf96442f4ca66bef5c1d3c7f1ea Signed-off-by: Neale Ranns <nranns@cisco.com>

2018-12-11Add IPSec interface FIB index for TX packetPierre Pfister1-0/+8
This patch adds a configuration parameter to IPSec tunnels, enabling custom FIB selection for encapsulated packets. Although this option could also be used for policy-based IPSec, this change only enables it for virtual-tunnel-interface mode. Note that this patch does change the API default behavior regarding TX fib selection for encapsulated packets. Previous behavior was to use the same FIB after and before encap. The new default behavior consists in using the FIB 0 as default. Change-Id: I5c212af909940a8cf6c7e3971bdc7623a2296452 Signed-off-by: Pierre Pfister <ppfister@cisco.com>

2018-07-08Fix IPsec intf tx node setup at intf creationMatthew Smith1-2/+2
When using a DPDK cryptodev with IPsec, sending outbound packets results in a crash on division by zero if using an algorithm not supported by the OpenSSL ESP nodes. This includes AES-GCM and MD5. At IPsec intf creation time, the next node at slot IPSEC_OUTPUT_NEXT_ESP_ENCRYPT for ipsec_if_tx_node_fn is set to the node named esp-encrypt. This is the OpenSSL ESP encrypt function. If DPDK cryptodevs are configured, dpdk-esp-encrypt is the correct next node. Change to setting the next node according to the value in ipsec_main.esp_encrypt_node_index. That value is set to esp-encrypt by default. If DPDK cryptodevs are configured it gets set to dpdk-esp-encrypt.

2018-04-19Allow an IPsec tunnel interface to be renumberedMatthew Smith1-28/+29
When creating an IPsec tunnel interface, allow a numeric identifier to be set for use in the interface's name in place of the dev instance. Default to using the dev instance if no value is explicitly set. When an IPsec tunnel is deleted, the interface is deleted now instead of being kept in a pool of available hw interfaces. Otherwise there was the possibility of conflicting tx node names between deleted tunnels and newly created ones.

2018-04-10Make IPsec tunnel intf work with IPv4 output featuresMatthew Smith1-0/+7
With no IPv4 output features on an IPsec tunnel inferface, when packets are forwarded to that interface, they reach the ipsec-if-output node via the output_node_index on the hw interface and they are handled correctly. When an IPv4 output feature (e.g. output ACL, outbound NAT) is enabled on an IPsec tunnel interface, outbound IPsec stops working for that interface. The last node in the ip4-output feature arc is interface-output. From there a packet is sent to ipsec<N>-output, and then ipsec<N>-tx. The tx function for an IPsec tunnel interface that is called by ipsec<N>-tx is a dummy that doesn't do anything except write a warning message. Enable a feature on the interface-output feature arc for an IPsec tunnel interface so the ipsec-if-output node is reached from the interface-output node.

2017-10-26Allow IPsec interface to have SAs resetMatthew Smith1-0/+79
Make it easier to integrate with external IKE daemon. IPsec interfaces can have one or both SAs replaced after creation. This allows for the possibility of setting a new child SA on an interface when rekeying occurs. It also allows for the possibility of creating an interface ahead of time and updating the SA when parameters that are negotiated during IKE exchange become known.

2017-10-05dpdk/ipsec: rework plus improved cli commandsSergio Gonzalez Monroy1-35/+43
This patch reworks the DPDK ipsec implementation including the cryptodev management as well as replacing new cli commands for better usability. For the data path: - The dpdk-esp-encrypt-post node is not necessary anymore. - IPv4 packets in the decrypt path are sent to ip4-input-no-checksum instead of ip4-input. The DPDK cryptodev cli commands are replaced by the following new commands: - show dpdk crypto devices - show dpdk crypto placement [verbose] - set dpdk crypto placement (<device> <thread> | auto) - clear dpdk crypto placement <device> [<thread>] - show dpdk crypto pools Change-Id: I47324517ede82d3e6e0e9f9c71c1a3433714b27b Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>

2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
