New subject: [PATCH 03/15] aead: fix for aead stream mode data length align problem

From: Wenkai Lin linwenkai6@hisilicon.com

The current aead stream mode restricts that all the data length of the update stage must be 16-byte aligned and a 0-byte tail packet is sent at the final stage, which leads to the total data length must be 16-byte aligned. This patch fix it by changing the time when the final packet is sent, if the data of update stage is not 16-byte aligned, a final packet will be sent immediately, and no operation is performed at the final stage, if the data at update stage is 16-byte aligned, keep the final packet to final stage. This change requires users to split data based on 16-byte alignment and then send the last non-16-byte aligned data.

When the length of aad is not 0 and the length of cipher len is 0, the stream does not enter the update stage and the mac is not set, fix it by copying mac before the first or update stage.

From: Wenkai Lin linwenkai6@hisilicon.com

First, use a stream mode to mark if a stream is async to avoid calling ASYNC_get_current_job every time. Then, the async job may not be obtained at the init stage, so make sure that data memory will be allocated.

New subject: [PATCH 07/15] async: avoid use zero to identify task type

From: Wenkai Lin linwenkai6@hisilicon.com

If task type is uninit, it will be zero, which is mistook as a cipher task and cause a recv timeout problem, so use 0x1 as start value of task type is better.
