From bf433416e67597ba105ece55b3136557874945db Mon Sep 17 00:00:00 2001 From: Lars Persson Date: Tue, 25 Aug 2015 11:59:15 +0200 Subject: [PATCH] crypto: algif_aead - fix for multiple operations on AF_ALG sockets The tsgl scatterlist must be re-initialized after each operation. Otherwise the sticky bits in the page_link will corrupt the list with pre-mature termination or false chaining.
