Patch to move the bind() so that ipV6 works
I've also tested that this patch does not break IPv4.

Description of problem: Multicast does not work over IPv6 corosync 2.3.5 but I suspect this goes back some way How reproducible: Every time Steps to Reproduce: 1. Set up a cluster to use IPv6 multicast 2. Start nodes Actual results: The nodes do not see each other. corosync-quorumtool shows that all the nodes are isolated Expected results: Cluster should form correctly. Additional info: This is specific to IPv6, IPv4 clusters are not affected. Also IPv6 clusters using updu are also fine. Here is my corosync.conf for testing. The other node has IP address ending in :2 of course. totem { version: 2 secauth: off cluster_name: small transport: udp interface { ringnumber: 0 mcastaddr: ff08::2 bindnetaddr: 2001:db8:1:0:200:11ff:fecc:1 ttl: 8 } ip_version: ipv6 nodeid: 1 } quorum { provider: corosync_votequorum expected_votes: 2 }
