2019-07-12ipsec: drop outbound ESP when no crypto alg setMatthew Smith1-1/+1
Type: fix If a tunnel interface has the crypto alg set on the outbound SA to IPSEC_CRYPTO_ALG_NONE and packets are sent out that interface, the attempt to write an ESP trailer on the packet occurs at the wrong offset and the vnet buffer opaque data is corrupted, which can result in a SEGV when a subsequent node attempts to use that data. When an outbound SA is set on a tunnel interface which has no crypto alg set, add a node to the ip{4,6}-output feature arcs which drops all packets leaving that interface instead of adding the node which would try to encrypt the packets.

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.

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.

2017-10-26Allow IPsec interface to have SAs resetMatthew Smith1-1/+1
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.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-0/+2
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

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>

Build Cryptodev IPsec support by default when DPDK is enabled but only build hardware Cryptodev PMDs. To enable Cryptodev support, a new startup.conf option for dpdk has been introduced 'enable-cryptodev'. During VPP init, if Cryptodev support is not enabled or not enough cryptodev resources are available then default to OpenSSL ipsec implementation.
