Description Kaushal 2016-03-01 08:14:38 UTC
When encryption is enabled on an rpc client, it can sometimes fail to reconnect.

This happens because, on the first reconnect attempt the underlying transport is freed if connect fails. Further reconnect attempts will not happen as the transport doesn't exist anymore.

This can lead to clusters showing inconsistent peer status information, and not performing correctly when management encryption is enabled.

    socket: Launch socket_poller only if connect succeeded
    
    For an encrypted connection, sockect_connect() used to launch
    socket_poller() in it's own thread (ON by default), even if the connect
    failed. This would cause two unrefs to be done on the transport, once in
    socket_poller() and once in socket_connect(), causing the transport to
    be freed and cleaned up. This would cause further reconnect attempts
    from failing as the transport wouldn't be available.
    
    By starting socket_poller() only if connect succeeded, this is avoided.
