- Add support for cmap node list configuration change - Add client side algorithms - Check if currently received ring id in membership message equals to last sent ring id - Send config node list only if config node list really changes and not after every reload - Add tlv_ring_id_eq (replacing qnetd_algo_rings_eq) so it's usable in client - Move debug logs from algo-test into qnetd-log-debug.c and call them in proper places (= logs are now algorithm independent) - Fix memory leak in msg Signed-off-by: Jan Friesse <jfriesse@redhat.com>
