From 555d3d5d2be13675490a80df0d7961551822ef1f Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Thu, 29 Nov 2007 08:56:16 -0500 Subject: [PATCH] SCTP: Fix chunk acceptance when no authenticated chunks were listed. In the case where no autheticated chunks were specified, we were still trying to verify that a given chunk needs authentication and doing so incorrectly. Add a check for parameter length to make sure we don't try to use an empty auth_chunks parameter to verify against.
