crypto: algif_aead - Only wake up when ctx->more is zero
[ Upstream commit f3c802a1f30013f8f723b62d7fa49eb9e991da23 ]
AEAD does not support partial requests so we must not wake up
while ctx->more is set. In order to distinguish between the
case of no data sent yet and a zero-length request, a new init
flag has been added to ctx.
SKCIPHER has also been modified to ensure that at least a block
of data is available if there is more data to come.
Fixes: 2d97591ef43d ("crypto: af_alg - consolidation of...")
