Subject: [PATCH RFC 0/2] tcp: allow to repair a tcp connections in closing states
Newsgroups: gmane.linux.kernel
Date: Thursday 10th April 2014 20:25:37 UTC (over 2 years ago)
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)
