Hi,
In geode-aes, there is not any IV generation mechanism. In fact IV is
delivered to geode-aes's
registered algorithms, from upper layers.For example in case of
"cbc-aes-geode" algorithm,
from cbc wrapper ("cbc.c") via walk->iv:
blkcipher_walk_init(&walk, dst, src, nbytes);
err = blkcipher_walk_virt(desc, &walk);
op->iv = walk.iv;
...
Regards.
