From 7462b9e9f69aa6c5e2fded65d3b03df4ed08ff45 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Mon, 18 Apr 2011 10:08:22 -0400 Subject: [PATCH] tipc: Fix problem with bundled multicast message Set the destination node and destination port fields of an outgoing multicast message header to zero; this is necessary to ensure that the receiving node can route the message properly if it was packed into a bundle due to link congestion. (Previously, there was a chance that the receiving node would send the unbundled message to a random node & port, rather than processing the message itself.)
