Follow-up Comment #5, bug #26301 (project lwip):

Agree with you,
replace with
pcb->rcv_nxt = seqno + tcplen;

and may be we can move string
where recalculated length of trimmed segment

tcplen = TCP_TCPLEN(&inseg);

to the place where it was trimmed

/* We have to trim the second edge of the incoming
segment. */
inseg.len = (u16_t)(pcb->ooseq->tcphdr->seqno - seqno);
pbuf_realloc(inseg.p, inseg.len);
+tcplen = TCP_TCPLEN(&inseg);
