1) both IPv4 and IPv6 mcast should default to ttl=1
2) the range should be 0..255
0 is valid meaning localhost only (cluster of one)

This option (-l or --less-secure) causes corosync-keygen to read from
/dev/urandom instead of /dev/random to ensure that no input is required
from the user. It may be useful when this command is used from a
script.

This is to send dbus events on major cluster events:
- membership changes
- application connect/dissconnet from corosync
- quorum changes
dbus events can then be converted into snmp traps by foghorn or
corosync-notifyd can be run to directly send snmp traps.

Some switches delay multicast packets vs the unicast token. This patch works
around that problem by providing a new tuneable called miss_count_const. This
tuneable works by counting the number of times a message is found missing
and once reaching the const value, marks it as missing in the retransmit list.
This improves performance and doesn't display warning messages about missed
multicast messages when operating in these switching environments.

The UDPU transport is useful for those deployments which can't use multicast.
UDPU works by using UDP unicast, which is fully supported by every switch
manufacturer by default and doesn't rely on a functional IGMP implementation.
An example of the UDPU transport is contained in the corosync.conf.example.udpu
file which shows a 16 node cluster. This file should be copied to each node
in the cluster and IP addresses changed as appropriate.
Amended to remove dead udpu REUSEADDR socket option.

Patch add support for Confdb integration with SAM. It's now possible to
use SAM_RECOVERY_POLICY_CONFDB as flag to previous policies.
Also new function sam_mark_failed is added for ability to use RECOVERY
policy together with confdb and get expected results (specially with
integration with corosync watchdog)
Patch also makes SAM thread safe.

in corosync.conf to explicitly state that you need to use
the network address, as opposed to "should always end in
zero", which is only correct for class C networks.

Patch adds integration of SAM and quorum, so it's now possible to use
SAM_RECOVERY_POLICY_QUORUM_QUIT or SAM_RECOVERY_POLICY_QUORUM_RESTART
recovery policy. With these policies, sam_start will block until
corosync is quorate. If quorum is lost during health checking, recovery
action is taken.
