From 435578aeaad5859dda8657e3ed2c1a5bc1e524ec Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 25 Jun 2009 14:46:31 +0800 Subject: [PATCH] crypto: skcipher - Fix request for sync algorithms When a sync givcipher algorithm is requested, if an async version of the same algorithm already exists, then we will loop forever without ever constructing the sync version based on a blkcipher. This is because we did not include the requested type/mask when getting a larval for the geniv algorithm that is to be constructed.
