new_route_len() ends with ``` if (num_acceptable_routers < 2) { log_info(LD_CIRC, "Not enough acceptable routers (%d). Discarding this circuit.", num_acceptable_routers); return -1; } if (num_acceptable_routers < routelen) { log_info(LD_CIRC,"Not enough routers: cutting routelen from %d to %d.", routelen, num_acceptable_routers); routelen = num_acceptable_routers; } ``` We should replace this with the simpler ``` if (num_acceptable_routers < 3) { log_info(LD_CIRC, "Not enough acceptable routers (%d). Discarding this circuit.", num_acceptable_routers); return -1; } ``` to simplify things. Note that the "oh hey let's just use two hops" case doesn't trigger in a real Tor network, because we won't be willing to make circuits if we don't have at least x% of the descriptors, so this code only comes into play when the consensus says there are 5 or something relays total.
