Currently connections only in the TCP_ESTABLISHED state can be dumped and restored. This series allows to restore connections in the FIN_WAIT_1, FIN_WAIT_2, LAST_ACK, CLOSE_WAIT, CLOSING or TIME_WAIT states.
v2: We decide to not use control message for repairing fin packets in queues. Because it looks quite tricky. Alexey suggested to restore each state separately and in this case setsockopt looks more logical.
Andrey Vagin (2): tcp: allow to enable repair mode for sockets in closing states tcp: add ability to restore closing states (v2)
