2021-04-20crypto: support async handlers for 3des and md5Alexander Chernavin1-3/+3
With this change, add support for 3DES and MD5 in IPsec async mode. After changes in foreach_crypto_link_async_alg, the last combination in the list (aes-256-cbc-hmac-sha-512) started to fail during decription. That was also fixed by proper vector size validation.

2021-04-09dpdk: selection of cryptodev engine data-pathFan Zhang1-2/+3
Type: improvement This patch combined cryptodev op and cryptodev raw API data paths into one and makes the engine run-timely select which data path is used: if all cryptodev devices support RTE_CRYPTODEV_FF_SYM_RAW_DP feature flag, the raw data path API is used, otherwise the traditional data path is used.

Type: fix vnet_crypto_is_set_handler() was checking if op handler is set by using alg instead of op id. This fix changes the check to use op ids from crypto_main's alg_data for provided alg. Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Change-Id: I5f0f00a889ddada44d9912af175ebad66677037a

2020-09-03crypto: SW scheduler async crypto enginePiotrX Kleski1-17/+65
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

2019-04-30crypto: enforce per-alg crypto key lengthBenoît Ganne1-2/+34
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).
