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
15a344f1d3
Don't respond with RST to ACKs in TCP 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.
2017-01-14 11:07:06 +00:00
