A commit token should be rejected when a token is lost in the recovery
state. This occurs naturally because the ring id increases by 4 for
every new ring. Prior to this patch, if the token was lost, the old
ring id information was restored, causing a commit token to be accepted
when it should be rejected. This erronously accepted commit token would
lead to an assertion which is fixed by this patch.

The included doxygen configuration file was a bit stale. It included
some options that were obsolete and caused doxygen to generate some
warnings when running it. Most of the changes here were simply done by
running "doxygen -u" to automatically update the file. It added its
documentation for the options and removed the obsolete options.
This also includes one configuration change, which is to set EXTRACT_ALL
to yes. This instructs doxygen to generate documentation pages for all
files, public functions, and public data structures even if they are not
currently documented using doxygen syntax. Doxygen is capable of
generating some useful documentation on its own, such as dependency
graphs.

From the strcpy(3) man page, the following warning is given:
The strncpy() function is similar, except that at most n bytes of src
are copied. Warning: If there is no null byte among the first n bytes
of src, the string placed in dest will not be null-terminated.
The current corosync code base does not take this warning into account
when using strncpy, potentially resulting in non-null terminated strings.

If the ring id file for the processor is less then 8 bytes, totemsrp would

When building corosync against older libraries already installed on the system,
the corosync-notifyd application uses the wrong Makefile.am commands. This
results in the SNMPLIBS (which includes -L/usr/lib64) coming before the proper
LDADD flags. The result is an inability to compile on an already existing
installation.

This patch adds a couple of missing calls to pthread_attr_destroy().
There were a couple of instances where pthread_attr_init() was being

localizes the pthread_attr_t to the function where it is needed instead
of having it persist (the man page specifically states that destroying

Right I know - not so good to comment out tests.
BUT they are passing but there is some weirdness
in ssh reconnecting to these nodes that causes CTS false
negatives.
So the nodes are watchdogged (as expected) but when they come
back up cts gets stuck in a loop re-trying to ssh into
them. It odd as a manual ssh works fine.
Basically I think it's more important the we get reliable
testing than have these test in there.

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.
