Even if the minimum blocksize is set to 16 (AES_BLOCK_SIZE), the crypto manager tests pass 499 bytes of data to the aes-ctr encryption, from which only 496 bytes are actually encrypted. Reading the comment regarding the minimum blocksize, it only states that it's the "smallest possible unit which can be transformed with this algorithm". Which doesn't necessarily mean, the data have to be a multiple of the minimal blocksize. All kernel hardware crypto driver enforce a minimum blocksize of 1, which perfect fine works for the lantiq data encryption unit as well. Lower the blocksize limit to 1, to process not padded data as well. In AES for processing the remaining bytes, uninitialized pointers were used. This patch fixes using uninitialized pointers and wrong offsets. Signed-off-by: Mathias Kresin <dev@kresin.me> [fix commit title prefix] Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de> |
