Follow-up Comment #6, bug #50476 (project lwip): Attached patch initializes ssthresh in tcp_alloc() and then removes all other initialize calls. This seemed simplest rather than having an assignment in both active open and passive open logic Also, I re-read RFC 5681 section 3.1 and my understanding is that the guidance is to set ssthresh arbitrarily high. The RFC provides an example of using the largest advertised receive window, but that's not required. Thus, using TCP_SND_BUF (LwIP's largest effect cwnd) is well within that guidance :) (file #39932) _______________________________________________________ Additional Item Attachment: File name: 0001-bug-50476-initialize-ssthresh-to-TCP_SND_BUF.patch Size:3 KB _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?50476> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
