[dpdk-dev] [PATCH] qat: fix checks for 3gpp algorithms vs bit mode

[Dmitry Eremin-Solenikov]

QAT driver checks byte alignment for KASUMI/SNOW 3G/ZUC algorithms using
cipher/auth_param, which are not initialized at this moment yet. Use
operation params instead.

[dpdk-dev] [PATCH v2] crypto/qat: fix checks for 3gpp algo bit params

[Fiona Trahe]

QAT driver checks byte alignment for KASUMI/SNOW 3G/ZUC algorithms using
cipher/auth_param, which are not initialized at this moment yet. Use
operation params instead.

Signed-off-by: Fiona Trahe <fiona.trahe@intel.com>

Change in v2 :
- fixed implementation to avoid data truncation

This fix should be backported to stable.
In 18.08 the code location has changed.
In earlier releases it was 
in qat_write_hw_desc_entry() in qat/qat_crypto.c

[Trahe, Fiona]

Hi Dmitri,

Thanks for debugging this. 
However the below fix can truncate the data - I'll send an alternative fix shortly.
