Comment (by mikeperry): Better idea: since malicious endpoints can withhold the ACK, we might as well just introduce a half-closed state for edge connections. With a simple struct, we can keep track of the outstanding END, SENDME windows, and data windows, and decrement those, and treat packets within the window as valid, until we get an END from the other side. This also has the advantage that we don't have to wait for anyone to upgrade. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25573#comment:4> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
