2019-01-02ipsec: fix support check when using AES-GCMMatthew Smith1-10/+15
When adding an IPsec SA, ipsec_check_support_cb() is called. This invokes a callback for AH and a callback for ESP to check if the algorithms are supported. When using AES-GCM on an ESP SA with the DPDK IPsec backend selected, the AH callback fails. The DPDK IPsec backend has no AH support, so the callback for the default OpenSSL backend is invoked. This checks whether the crypto algorithm is AES-GCM and returns failure. Only invoke the callback to check support for the IPsec protocol of the SA - either AH or ESP rather than doing both.

2018-12-12Change ipsec feature node namesPierre Pfister4-24/+24
ipsec4-output and ipsec6-output were conflicting with ipsec interface names ("ipsec<id>") and vnet/interface.c autogenerated output node ("<ifname>-output"). Changing feature names seems to be the less invasive option. This patch also changes "input" feature names for consistency.

2018-12-11Add IPSec interface FIB index for TX packetPierre Pfister6-6/+36
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.

2018-05-10Change the way IP header pointer is calculated in esp_decrypt nodesSzymon Sliwa2-3/+11
The pointer to IP header was derived from l3_hdr_offset, which would be ok, if l3_hdr_offset was valid. But it does not have to be, so it was a bad solution. Now the previous nodes mark whether it is a IPv6 or IPv4 packet tyle, and in esp_decrypt we count get ip header pointer by substracting the size of the ip header from the pointer to esp header (which lies in front of the ip header).

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.
