First of all -- to make crtools dump/restore established tcp sockets you have to specify the --tcp-established options. By doing so you inform crtools that a) you know, that after dump there will be a netfilter rules blocking the dumped connections b) you guarantee, that before restore this netfilter block is still there What else this patch does is simple -- collects establised sockets and calls the dump/restore tcp function (now empty) where appropriate.
