If CTDB_USE_IPV6 is set then use IPv6 addresses for nodes and public
IPs. This can be useful for some simple tests. However, the node
address actually needs to be on lo so that ctdbd can bind to the port
on that address, so they actually need to be added as root before
running tests, like this:
for i in $(seq 1 10) ; do ip addr add "fc00:10::${i}/64" dev lo ; done
IPv4 127.0.0.0/8 addresses are somehow magic and only one needs to be
on lo so that many can be bound to.
Also change the IPv4 node addresses to be (slightly) more exotic.
For both IPv4 and IPv6, choose addresses that are compatible with
socket wrapper.

There are a few potential failure modes when adding an IPv6 address.
It takes a little while of duplicate address detection to complete, so
wait for a while. After a timeout, also need to check to see if
duplicate address detection failed - if it did then actually drop the
IP address.
This really needs some careful thinking. If CTDB disappears on a node
but the node's IP addresses are still on interfaces then the above
failure mode could cause the takeover nodes to become banned.

ctdb_sys_find_ifname() doesn't work for IPv6 addresses so don't use
it.
Trust the eventscript to do sanity checking on the interface. Current
warnings are replaced with equivalents generated by the eventscript.
The unlikely message:
Public IP %s is hosted on interface %s but we have no VNN
will be replaced by:
WARNING: Public IP %s hosted on interface %s but VNN says __none__
which is clear enough.

Add checking to "releaseip" and "updateip" to ensure that the given IP
address is really on the given interface with the given netmask. If
reality doesn't match the given arguments then believe reality.
Use new function iptables_wrapper() instead of calling iptables()
directly.
Use new function flush_route_cache() instead of doing IPv4-specific
/proc magic.
Remove setting of otherwise unused variable "failed".

When watching two subdirectories with inotify and a file is moved between both,
we get a IN_MOVED_FROM for the source watch and a IN_MOVED_TO for the
destination watch. Without this patch we create a NOTIFY_ACTION_OLD_NAME for
the old directory. We hold this back in notify_fsp, expecting the NEW_NAME
immediately after it. In the cross-directory rename case this does not work,
we'll not get the NEW_NAME, there is no NEW_NAME in that directory.
This patch changes us to create NOTIFY_ACTION_REMOVED and NOTIFY_ACTION_ADDED
in this case. Not sure this is right, but at least it is better than before: We
get something at all.
This is more likely to happen with the notifyd approach, as there we
inotify-watch many subdirectories from one process. Without nootifyd you had to
have two explorer windows open and do a nfs or local mv between those two
directories to find this.
