commit 4ccf09b1c21a858540453287e58a478a80a598ae Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Jan 14 14:02:13 2013 -0500 Reject create/begin/etc cells with {circ,stream}ID 0. Otherwise, it's possible to create streams or circuits with these bogus IDs, leading to orphaned circuits or streams, or to ones that can cause bandwidth DOS problems.
