From 1e1229940045a537c61fb69f86010a8774e576d0 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Thu, 29 Mar 2012 09:03:47 +0200 Subject: crypto: user - Fix lookup of algorithms with IV generator We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg().
