pacemaker.shar

lib/services/services_linux.c and lib/common/utils.c patches have been
committed upstream. extra/resources/ping and crmd/throttle.c are trivial, but I
haven't submitted them yet.  The crmd/pengine.c patch is just to lower the
default message size for FreeBSD specifically due to the default
kern.ipc.maxsockbuf sysctl.  This patch is purely to have pacemaker work
without having to tweak it.  In my simple testing I was only able to max out
the message size when creating hundreds of ping resource agents.  If someone
runs into a problem they could always increase the sysctl and set the
pacemaker_ipc_buffer rc variable to something larger.

The only resource agent I've tested and patched was ping, I doubt the others
will work.  I just haven't got around to looking at them.  pacemaker itself
though appears to run fine in a simple 2 node zabbix setup.  I also had a 3
node setup between debian8/freebsd9/freebsd10 working too.
