There is no need to walk the pbuf chain, pbuf_free() does that for
you. Calling tcp_recved() many times doesn't look right: that will
cause many redundant receive window update packets from lwip. Just
call it once with buf->tot_len.
err_t newdata(void *arg, struct tcp_pcb *pcb, struct pbuf *buf, err_t err)
{
tcp_recved(pcb, buf->tot_len);
pbuf_free(buf);
return ERR_OK;
}
