2020-12-04crypto: fixed vnet_crypto_async_reset_frame assertPiotrX Kleski1-1/+2
Type: fix Changed vnet_crypto_async_reset_frame assert to expect also ERROR state frames. Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Change-Id: I3abc29f3f9642027aee38a59a932e54c90da859d
2020-12-04crypto: fixed async frame enqueue race conditionPiotrX Kleski1-2/+8
Type: fix To avoid race condition happening in async crypto engines, async frame state and thread index set should happen before enqueue. In addition as the enqueue handler already returns the enqueue status, when an enqueue is failed, the async crypto engine shall not worry about setting the async frame state but let the submit_open_frame function to do just that.

2020-09-03crypto: SW scheduler async crypto enginePiotrX Kleski1-10/+34
Type: feature This patch adds new sw_scheduler async crypto engine. The engine transforms async frames info sync crypto ops and delegates them to active sync engines. With the patch it is possible to increase the single worker crypto throughput by offloading the crypto workload to multiple workers. By default all workers in the system will attend the crypto workload processing. However a worker's available cycles are limited. To avail more cycles to one worker to process other workload (e.g. the worker core that handles the RX/TX and IPSec stack processing), a useful cli command is added to remove itself (or add it back later) from the heavy crypto workload but only let other workers to process the crypto. The command is: - set sw_scheduler worker <idx> crypto <on|off> It also adds new interrupt mode to async crypto dispatch node. This mode signals the node when new frames are enqueued as opposed to polling mode that continuously calls dispatch node. New cli commands: - set crypto async dispatch [polling|interrupt] - show crypto async status (displays mode and nodes' states) Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Signed-off-by: DariuszX Kazimierski <dariuszx.kazimierski@intel.com> Reviewed-by: Fan Zhang <roy.fan.zhang@intel.com> Change-Id: I332655f347bb9e3bc9c64166e86e393e911bdb39

2019-07-24ipsec: GCM, Anti-replay and ESN fixessNeale Ranns1-2/+1
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>

2019-04-30crypto: enforce per-alg crypto key lengthBenoît Ganne1-14/+16
Crypto algorithms have different requirements on key length. As we do not support key stretching (eg. PBKDF2), user must provide the exact key length used by the algorithm. Failing that means low-level crypto functions might read garbage (eg. aes128_key_expand() will read 16-bytes, regardless of the key provided by the user).
