crypto: algif_hash - Require setkey before accept(2)
[ Upstream commit 6de62f15b581f920ade22d758f4c338311c2f0d4 ]
Hash implementations that require a key may crash if you use
them without setting a key. This patch adds the necessary checks
so that if you do attempt to use them without a key that we return
-ENOKEY instead of proceeding.
This patch also adds a compatibility path to support old applications
that do acept(2) before setkey.
