2021-02-09crypto: fix bad-hmac in sw scheduler if async modeAlexander Chernavin1-0/+1
When IPsec async mode is enabled, packets don't pass through the tunnel if ciphers other than AES GCM are used for child SAs. An error that arises is "bad-hmac" in the "crypto-dispatch" node. On the encryption stage, the VNET_CRYPTO_OP_FLAG_HMAC_CHECK flag is set for the integrity crypto operation when it's not supposed to. It seems that the flag remains from the previous operation. With this change, zero flags of crypto operations in the SW scheduler during operation filling.

2020-12-04crypto: fixed async frame enqueue race conditionPiotrX Kleski1-2/+0
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 Kleski3-0/+791
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
