Pavel Emelyanov	f9a8673d52	tcp: Dump and restore support ... What it does is uses the tcp repair engine from the kernel. On dump the connection is locked with netfilter, socket is put in the repair state and then its internals are dumped. On restore we create a socket, put it into repair, dress it up and then unlock all the connections at the very end. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>	2012-04-28 17:59:21 +04:00
Pavel Emelyanov	675b4698ce	tcp: Put connection locking management over the code ... When dump finished with error we should unlock all locked previously connections. When restoring we should collect connctions and unlock them all at the end. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>	2012-04-28 17:59:21 +04:00
