Re: [lwip-users] TCP state machine problem? LWIP 1.4.1

[Fabian Koch]

Update: 

Even when copying the current LWIP master state of the top of tcp_process() to 
my 1.4.1 working copy, the behavior still results in this RST/ACK pingpong.

I fear that something in tcp_receive() has changed as well or even deeper?

At least in the referenced bug report, the current state of master seems to 
have helped. My only idea right now is to blame it on the IP stack of the peer 
but that is a bit counterproductive right now.

Any further ideas or help in this?

Kind regards
Fabian

I guess this is what I remember... not exactly your problem nor a helping hand 
but perhaps you can start digging here:
