crypto: arm64-aes - fix encryption of unaligned data
cryptsetup fails on arm64 when using kernel encryption via AF_ALG socket. See https://bugzilla.redhat.com/show_bug.cgi?id=1122937 The bug is caused by incorrect handling of unaligned data in arch/arm64/crypto/aes-glue.c. Cryptsetup creates a buffer that is aligned on 8 bytes, but not on 16 bytes. It opens AF_ALG socket and uses the socket to encrypt data in the buffer. The arm64 crypto accelerator causes data corruption or crashes in the scatterwalk_pagedone. This patch fixes the bug by passing the residue bytes that were not processed as the last parameter to blkcipher_walk_done. Signed-off-by:Mikulas Patocka <mpatocka@redhat.com> Acked-by:
