>context: 1 2 3 4 5 6 7 8 9 10 15 20 25 30 35 40 space: include ignore mode: unified ssdiff stat only crypto: arm64/aes-blk - honour iv_out requirement in CBC and CTR modes
Update the ARMv8 Crypto Extensions and the plain NEON AES implementations
in CBC and CTR modes to return the next IV back to the skcipher API client.
This is necessary for chaining to work correctly.
Note that for CTR, this is only done if the request is a round multiple of
the block size, since otherwise, chaining is impossible anyway.
