Bug Description

The cluster controller's ip information looks like this:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:16:d3:ca:e8:1e brd ff:ff:ff:ff:ff:ff
    inet 10.1.1.131/24 brd 10.1.1.255 scope global eth0
    inet 169.254.169.254/32 scope global eth0
    inet6 fe80::216:d3ff:feca:e81e/64 scope link
       valid_lft forever preferred_lft forever

When avahi is asked for this system's ip address by its avahi hostname, sometimes it returns 10.1.1.131, and sometimes it returns 169.254.169.254.

Unfortunately, 169.254.169.254 isn't very useful to other nodes.

We already have some special case logic in euca_find_cluster that prefers an ipv4 address over an ipv6 address.

We need some additional logic to avoid the 169.254.169.254, and use the suggested ip address of the CC.

By "suggested IP address", a secondary change is necessary in the avahi-publish to use the $CC_IP_ADDR of the system as the "name" of the service. Previously, this was $(hostname).

Shouldn't that be using "scope link"? I don't know if that would matter for this bug, but it seems a bit odd for it to be a global scope address. Might be harmless though.

  * Merge upstream revision 916
  * This snapshot is expected to fix the following bugs:
    - LP: #443314 - fix system address selection
    - LP: #443325 - fix regression in heartbeat, fix NPE in system mode
    - LP: #444838 - fix meta-data service in multi-cluster

    - LP: #445206 - fix remote bootstrap on walrus+sc
  * debian/eucalyptus-cc.eucalyptus-cc-publication.upstart,
    debian/local/euca_find_cluster.c: when doing the avahi-publish, use
    $CC_IP_ADDR rather than $(hostname) for the "name" of the service;
    use this ip address in the case where euca_find_cluster gets the
    link-local 169.254.169.254 address, LP: #445738
