crypto: atmel-aes - Detecting in-place operations two sg lists

Browse source

Avoiding detecting finely in-place operations with different
scatter lists. Copying the source data for decryption into rctx->lastc
regardless if the operation is in-place or not. This allows in-place
operations with different scatter lists.

This approach takes less resources than parsing both scatter lists to
check if they are equal.
