2019-11-07dpdk: ipsec gcm fixesChristian Hopps1-1/+4
- Fix AAD initialization. With use-esn the aad data consists of the SPI and the 64-bit sequence number in big-endian order. Fix the u32 swapped code. - Remove salt-reinitialization. The GCM code seems inspired by the GCM RFCs recommendations on IKE keydata and how to produce a salt value (create an extra 4 octets of keying material). This is not IKE code though and the SA already holds the configured salt value which this code is blowing away. Use the configured value instead.

2019-08-15dpdk: ipsec tunnel support for ip6-in-ip4Matthew G Smith1-2/+1
Type: feature If an attempt was made to send an IPv6 packet over an IPv4 tunnel, the DPDK esp_encrypt did not complete setting up the crypto operation for a buffer, but still queued the crypto operations that were allocated. This results in a SEGV when attempting to dequeue them in dpdk-crypto-input. Allow IPv6 packets to be sent over a v4 tunnel when using the DPDK plugin esp crypto nodes.

2019-07-24ipsec: GCM, Anti-replay and ESN fixessNeale Ranns1-2/+4
Type: fix Several Fixes: 1 - Anti-replay did not work with GCM becuase it overwrote the sequence number in the ESP header. To fix i added the seq num to the per-packet data so it is preserved 2 - The high sequence number was not byte swapped during ESP encrypt. 3 - openssl engine was the only one to return FAIL_DECRYPT for bad GCM the others return BAD_HMAC. removed the former 4 - improved tracing to show the low and high seq numbers 5 - documented the anti-replay window checks 6 - fixed scapy patch for ESN support for GCM 7 - tests for anti-reply (w/ and w/o ESN) for each crypto algo Change-Id: Id65d96b6d1d4dd821b2ab557e87468fff6d70e5b Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-05-17dpdk-ipsec: fix encrypt/decrypt single queueSergio Gonzalez Monroy1-2/+3
When the same worker thread processes packet for encrypt and decrypt, ie. single worker with bi-directional traffic, given that the queue is shared results in packets to be decrypted being dropped as the encrypt always happens first for each main loop. With this change, each crypto device queue is logically split into two queues, each half the real size, avoiding the described problem.

2018-10-23dpdk: add esp6 decrypt nodes, func declarationsMatthew Smith1-0/+30
The function dpdk_ipsec_process() attempts to initialize some globals that store node indexes after looking up the node dpdk-esp6-decrypt. No such node was declared, so a segv occurs after dereferencing the result of the lookup. Add a node function that invokes dpdk_esp_decrypt_inline() with is_ip6 set to 1. Add a declaration of node dpdk-esp6-decrypt that uses the node function. Change-Id: I31ce23a458c2d4181bf40cbc2118c4ef3b9baf97 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2018-05-10Change the way IP header pointer is calculated in esp_decrypt nodesSzymon Sliwa1-1/+7
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).

2017-10-05dpdk/ipsec: rework plus improved cli commandsSergio Gonzalez Monroy1-179/+232
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 Marion1-2/+2
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.
