Closing this as duplicate since Roy responded on lwip-devel: "Sure, thank you."

Roy: can this now be resolved as a duplicate of bug #25094?  It seems like the patch you submitted there will address this as well.

Could you go into detail on this? Is it the same bug I discovered on bug #25094? If so, the solution for this should be as simple as making sure that tcp_connect only needs ONE pbuf?

Wed 15 Apr 2009 01:51:14 PM UTC, original submission:  

Currently, tcp_connect()->tcp_enqueue() forms an two-pbuf segment, which
breaks the assumption in the SYN_SENT case clause of tcp_process().

Either the above assmuption should be removed, or the code flow of
tcp_connect() needs to be reviewed.
