[lwip-devel] SYN-SENT state does not accept SYN only segment

[narke]

Hi,

I found in lwIP,  when an active open pcb in its SYN-SENT state and
received an segment sent from peer which has SYN flag but w/o ACK
flag,  the pcb just ignore the segment.  However, in RFC 793, it is
required to accept the SYN only segment in SYN-SENT state and switch
to SYN-RCVD state.

Can anyone please confirm this?  It's a bug or a dedicated design?

Thanks in advance.
