From e9a034456a8cd766795610aa5065263147e35228 Mon Sep 17 00:00:00 2001 From: Jon Maloy Date: Fri, 12 Jan 2018 20:56:50 +0100 Subject: tipc: fix bug during lookup of multicast destination nodes In commit 232d07b74a33 ("tipc: improve groupcast scope handling") we inadvertently broke non-group multicast transmission when changing the parameter 'domain' to 'scope' in the function tipc_nametbl_lookup_dst_nodes(). We missed to make the corresponding change in the calling function, with the result that the lookup always fails. A closer anaysis reveals that this parameter is not needed at all. Non-group multicast is hard coded to use CLUSTER_SCOPE, and in the current implementation this will be delivered to all matching destinations except those which are published with NODE_SCOPE on other nodes. Since such publications never will be visible on the sending node anyway, it makes no sense to discriminate by scope at all. We now remove this parameter altogether.
