| + | In-flight connections can happen on sockets which do not yet have a full [https://en.wikipedia.org/wiki/Transmission_Control_Protocol#CONNECTION-ESTABLISHMENT established connection]. |
| + | For instance, when establishing a TCP connection using a three-way [https://en.wikipedia.org/wiki/Handshaking handshake], '''SYN''' and '''SYN-ACK''' have been exchanged but the final '''ACK''' is not send back to the server. |
| + | |
| + | CRIU can handle the checkpoint of sockets in this state with the <code>--skip-in-flight</code> option, which will ignore not yet completely established TCP connections. On restore the client is expected to handle the re-connection. |
