Since in the software implementation of XTS-AES there is no notion of sector every input length is processed the same way. CAAM implementation has the notion of sector which causes different results between the software implementation and the one in CAAM for input lengths bigger than 512 bytes. Increase sector size to maximum value on 16 bits.
Fixes: c6415a6016bf ("crypto: caam - add support for acipher xts(aes)") Cc: stable@vger.kernel.org # v4.12+ Signed-off-by: Andrei Botila andrei.botila@nxp.com
This patch needs to be applied from v4.12+ because dm-crypt has added support for 4K sector size at that version. The commit was 8f0009a225171 ("dm-crypt: optionally support larger encryption sector size").
