79b54a624e change the takoverip/releaseip controls to pass a structure containing 
both the nodenumber and the id of the node that has taken over that 
address in addition to the public address itself    so that all nodes 
can learn which node is currently hosting each of the public addresses

9cc3ce8554 automatic cleanup of tcp tickle records 
(This used to be ctdb commit ede79b571bf89b89f1b8394f262ca0689f8c65f3)
 2007-05-28 00:34:40 +10:00
Andrew Tridgell
d41290fbae added code to ctdb to send a tcp 'tickle' ack when we takeover an 
IP. A raw tcp ack is sent for each tcp connection held by clients
before the IP takeover.

These acks have a deliberately incorrect sequence number, and should
cause the windows client to send its own ack which will in turn cause
a tcp reset and thus cause windows clients to much more quickly
reconnect to the new node.
