34d32f67a2
Gate the really verbose log messages behind a feature.

Otherwise, trying to use the socket buffers instead of BufReader/
BufWriter is doomed to overwhelm the application logic.
2017-01-19 12:23:32 +00:00

Don't respond with RST to ACKs in TCP LISTEN state.
...
These packets may have been destined for a different socket.

591993014e
Reject, not accept, TCP RST packets in LISTEN state.

578d7bce5f
Calculate IP payload length from the total length field.
...
Before this commit, IP payload length was calculated by subtracting
the IP header length from the total underlying buffer length, which
fails if the underlying buffer has padding, e.g. like Ethernet
does.

This may interact badly with other tooling.
