Subject: [PATCH 011/116] crypto: starfive - Pad adata with zeroes
|
|
|
|
Aad requires padding with zeroes up to 15 bytes in some cases. This
|
|
patch increases the allocated buffer size for aad and prevents the
|
|
driver accessing uninitialized memory region.
|
|
|
|
v1->v2: Specify reason for alloc size change in descriptions.
