Subject[PATCH 4.2.y-ckt 002/218] crypto: algif_skcipher - Add key check exception for cipher_null
Date
4.2.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Herbert Xu <herbert@gondor.apana.org.au>

commit 6e8d8ecf438792ecf7a3207488fb4eebc4edb040 upstream.

This patch adds an exception to the key check so that cipher_null
users may continue to use algif_skcipher without setting a key.
