Tue 05 Jul 2016 03:30:54 PM UTC, comment #5: I reviewed RFC 793 and I think the only check we aren't doing is if the ACK is acceptable and no SYN is contained, then the packet is silently ignored.

Mon 04 Jul 2016 08:39:41 AM UTC, comment #3: I don't think that any check is needed. An alternative would be to substantially reduce the retransmission timeout (which seems excessively high at three seconds). This patch is intended to be a less intrusive change. |

Mon 04 Jul 2016 08:31:44 AM UTC, comment #2: Looks good, but do we need a check on ackno of the incoming ACK segment to prevent sending too much SYN segments? I think we don't, but I'm not absolutely sure... |

Definitively worth mentioning. Event worth fixing if it's a tiny fix... OTOH, it doesn't seem to be a real-world-problem ;-)
