# - There ought to be an ocf_run_cmd function which does all logging,

# - Make this the standard IP address agent on Linux; the other
# platforms simply should ignore the additional parameters OR can use
# the legacy heartbeat resource script...
# - Check LVS <-> clusterip incompatibilities.

<resource-agent name="IPaddr2" version="1.0">
<version>1.0</version>
<longdesc lang="en">
This Linux-specific resource manages IP alias IP addresses.
It can add an IP alias, or remove one.
In addition, it can implement Cluster Alias IP functionality
if invoked as a clone resource.
If used as a clone, "shared address with a trivial, stateless
(autonomous) load-balancing/mutual exclusion on ingress" mode gets
applied (as opposed to "assume resource uniqueness" mode otherwise).
For that, Linux firewall (kernel and userspace) is assumed, and since
recent distributions are ambivalent in plain "iptables" command to
particular back-end resolution, "iptables-legacy" (when present) gets
prioritized so as to avoid incompatibilities (note that respective
ipt_CLUSTERIP firewall extension in use here is, at the same time,
marked deprecated, yet said "legacy" layer can make it workable,
literally, to this day) with "netfilter" one (as in "iptables-nft").
In that case, you should explicitly set clone-node-max >= 2,
and/or clone-max < number of nodes. In case of node failure,
clone instances need to be re-allocated on surviving nodes.
This would not be possible if there is already an instance
on those nodes, and clone-node-max=1 (which is the default).
When the specified IP address gets assigned to a respective interface, the
resource agent sends unsolicited ARP (Address Resolution Protocol, IPv4) or NA
(Neighbor Advertisement, IPv6) packets to inform neighboring machines about the
change. This functionality is controlled for both IPv4 and IPv6 by shared
'arp_*' parameters.
</longdesc>
<shortdesc lang="en">Manages virtual IPv4 and IPv6 addresses (Linux specific version)</shortdesc>
<parameters>
<parameter name="ip" unique="1" required="1">
<longdesc lang="en">
The IPv4 (dotted quad notation) or IPv6 address (colon hexadecimal notation)
example IPv4 "192.168.1.1".
example IPv6 "2001:db8:DC28:0:0:FC57:D4C8:1FFF".

<parameter name="nic" unique="0">
<longdesc lang="en">
The base network interface on which the IP address will be brought
online.
If left empty, the script will try and determine this from the
routing table.
Do NOT specify an alias interface in the form eth0:1 or anything here;
rather, specify the base interface only.
If you want a label, see the iflabel parameter.
Prerequisite:
There must be at least one static IP address, which is not managed by
the cluster, assigned to the network interface.
If you can not assign any static IP address on the interface,
modify this kernel parameter:
sysctl -w net.ipv4.conf.all.promote_secondaries=1 # (or per device)

The netmask for the interface in CIDR format

<parameter name="broadcast">

Broadcast address associated with the IP. It is possible to use the

case, the broadcast address is derived by setting/resetting the host
bits of the interface prefix.

</parameter>
<parameter name="iflabel">
<longdesc lang="en">
You can specify an additional label for your IP address here.
This label is appended to your interface name.
The kernel allows alphanumeric labels up to a maximum length of 15
characters including the interface name and colon (e.g. eth0:foobar1234)
A label can be specified in nic parameter but it is deprecated.
If a label is specified in nic name, this parameter has no effect.

Enable support for LVS Direct Routing configurations. In case a IP
address is stopped, only move it to the loopback device to allow the
local node to continue to service requests, but no longer advertise it

Notes for IPv6:
It is not necessary to enable this option on IPv6.

Enable adding IPv6 address label so IPv6 traffic originating from
the address's interface does not use this address as the source.
This is necessary for LVS-DR health checks to realservers to work. Without it,
the most recently added IPv6 address (probably the address added by IPaddr2)
will be used as the source address for IPv6 traffic from that interface and
since that address exists on loopback on the realservers, the realserver
response to pings/connections will never leave its loopback.
See RFC3484 for the detail of the source address selection.
See also 'lvs_ipv6_addrlabel_value' parameter.

Specify the interval between unsolicited ARP (IPv4) or NA (IPv6) packets in

to use connections for some time even after the
IP address is deconfigured. Set this parameter in

# Description: IPsrcaddr - Preferred source(/dest) address modification
#
# Author: John Sutton <john@scl.co.uk>
# Support: users@clusterlabs.org
# License: GNU General Public License (GPL)
# Copyright: SCL Internet
#
# Based on the IPaddr script.
#
# This script manages the preferred source address associated with
# packets which originate on the localhost and are routed through the
# matching route. By default, i.e. without the use of this script or
# similar, these packets will carry the IP of the primary i.e. the
# non-aliased interface. This can be a nuisance if you need to ensure
# that such packets carry the same IP irrespective of which host in
# a redundant cluster they actually originate from.
#
# It can add a preferred source address, or remove one.
#
# usage: IPsrcaddr {start|stop|status|monitor|validate-all|meta-data}
#
# The "start" arg adds a preferred source address.
#
# Surprisingly, the "stop" arg removes it. :-)
#
# NOTES:
#
# 1) There must be one and not more than 1 matching route! Mainly because
# I can't see why you should have more than one. And if there is more
# than one, we would have to box clever to find out which one is to be
# modified, or we would have to pass its identity as an argument.
#
# 2) The script depends on Alexey Kuznetsov's ip utility from the
# iproute aka iproute2 package.
#
# 3) No checking is done to see if the passed in IP address can
# reasonably be associated with the interface on which the default
# route exists. So unless you want to deliberately spoof your source IP,
# check it! Normally, I would expect that your haresources looks
# something like:
#
# nodename ip1 ip2 ... ipN IPsrcaddr::ipX
#
# where ipX is one of the ip1 to ipN.
#
# OCF parameters are as below:
# OCF_RESKEY_ipaddress
