With this option set to "yes", we don't become unhealthy
as long as at least one interface is still available.

When two releaseip events run in parallel it's possible that the 2nd script
readds a secondary ip that was removed by the 1st script.

This is needed because the "startup" event runs after the initial recovery,
but we need to do some actions before the initial recovery.

when checking link status for an interface, first
check if this interface is in fact a bond device
(by the precense of a /proc/net/bonding/IFACE file)
and use that file for checking status.
Othervise assume ib* is an infiniband interface which we donnt know how
to check, or otherwise it is an ethernet interface and ethtool should
hopefully work.

The functions file no longer causes a side-effect by doing a shift.
It also doesn't set a convenience variable for $1.
All eventscripts now explicitly use "$1" in their case statement, as
does the initscript. The absence of a shift means that the
takeip/releaseip events now explicitly reference $2-$4 rather than
$1-$3.
New function ctdb_standard_event_handler handles the status and
setstatus events, and exits for either of those events. It is called
via a default case in each eventscript, replacing an explicit status
case where applicable.

this to handle the case where all links do have a physical layer, but where all slaves have been disabled using ifdown
(This used to be ctdb commit bf50709630df000583f2b0ef0edc177c01d60eaf)
On some systems, the ethtool link detection is not successful when a
cable is plugged but the interface has not been brought up previously.
This improves the test by bringing the interface up (without checking
for success here) and trying the ethtool test again afterwards.

Let the event complete successfully. the local recovery daemon will check that we have the address and reissue takip othervise.
There are several reasons why "ip addr add " can fail, one is a misconfiguration
anothe ris that for ipv6 the stack is a lot more picky than for ipv4. for examplke this WILL fail in ipv6 if there is a duplicate ip address on the network.
thus this check could cause rolling-recoveries which is why it has to go

If we use vlan tagging and bonding we must strip the vlan part off the name
so we can check the main bonde device for status.
I.e. check bond0 instead of bond0.<VLANTAG>

into a case and add an arm for ib*) (infiniband interfaces)
Dont try using ethtool on ib devices
(mii_tool doesnt work either)
IB does have a command ibv_devinfo which can tell whether a physical port
is up or not but it seems nontrivial to map this into a interface name such as ib0

- put removed IPs on loopback with scope host

a bool that specifies whether the ip was held by a loopback adaptor or
not
the name of the interface where the ip was held
when we release an ip address from an interface, move the ip address
over to the loopback interface
when we release an ip address after we have move it onto loopback,
use 60.nfs to kill off the server side (the local part) of the tcp
connection so that the tcp connections dont survive a
failover/failback
61.nfstickle, since we kill hte tcp connections when we release an ip
address we no longer need to restart the nfs service in 61.nfstickle
update ctdb_takeover to use the new signature for ctdb_sys_have_ip
when we add a tcp connection to kill in ctdb_killtcp_add_connection()
check if either the srouce or destination address match a known public
address

10.interfaces startsup
this setting makes the system only respond to APR requests from the NIC
where the ip address is tied to and adds to the
"principle of least surprise" when using multihoming servers

multiple public addresses spread across multiple interfaces on each
node.
this is a massive patch since we have previously made the assumtion that
we only have one public address per node.
get rid of the public_interface argument. the public addresses file
now explicitely lists which interface the address belongs to

- added monitoring of the ethernet link state
When monitoring detects an error, the node loses its public IP address
