Created attachment 586655 [details] Backported patch from needle Description of problem (test case): It's impossible to bind to concrete IP if there is previous network which is same as first one. Version-Release number of selected component (if applicable): Corosync in RHEL 6.3 (same in flatiron git) How reproducible: 100% TEST CASE: Steps to Reproduce: 1. multiple IPs with same net ip addrs ... inet 10.34.38.161/24 brd 10.34.38.255 scope global eth0 inet 10.34.38.215/24 scope global secondary eth0 ... 2. set bindnetaddr to second IP (10.34.38.215) 3. corosync Actual results: In log ... The network interface [10.34.38.161] is now up. ... And corosync is really bound to 161 Expected results: ... The network interface [10.34.38.215] is now up. ... And corosync should be really bound to 215

New Contents: Cause User has two IPs on same network and try to use second one. Consequence Corosync binds to first IP.
