[tor/master] hs: Fix possible integer underflow with IP nodes
by nickm＠torproject.org 03 Feb '17

commit cc0342a2ae4264c5b8796e2731a51272342bb8f4 Author: David Goulet <dgoulet(a)torproject.org> Date: Wed Feb 1 11:07:09 2017 -0500 hs: Fix possible integer underflow with IP nodes In rend_consider_services_intro_points(), we had a possible interger underflow which could lead to creating a very large number of intro points. We had a safe guard against that *except* if the expiring_nodes list was not empty which is realistic thing. This commit removes the check on the expiring nodes length being zero. It's not because we have an empty list of expiring nodes that we don't want to open new IPs. Prior to this check, we remove invalid IP nodes from the main list of a service so it should be the only thing to look at when deciding if we need to create new IP(s) or not. Partially fixes #21302.

[tor/master] hs: Fix an underflow in rend_service_intro_has_opened()

commit 8573d994706c16628bb60e0aabdb9a5190beff13 Author: David Goulet <dgoulet(a)torproject.org> Date: Wed Feb 1 11:22:17 2017 -0500 hs: Fix an underflow in rend_service_intro_has_opened() In rend_service_intro_has_opened(), this is subject to a possible underflow because of how the if() casts the results. In the case where the expiring nodes list length is bigger than the number of IP circuits, we end up in the following situation where the result will be cast to an unsigned int.
