[tor/master] Don't accept posted votes after :52:30
by nickm＠torproject.org 20 Feb '20

20 Feb '20

commit acb5b0d535dae67b6a85780b4ae54bcf415e79fc Author: Roger Dingledine <arma(a)torproject.org> Date: Wed Jan 29 07:31:19 2020 -0500 Don't accept posted votes after :52:30 If we receive via 'post' a vote from a dir auth after the fetch_missing_votes cutoff, that means we didn't get it by the time we begin the "fetching missing votes from everybody else" phase, which means it is very likely to cause a consensus split if we count it. Instead, we reject it. But we still allow votes that we fetch ourselves after that cutoff. This is a demo branch for making progress on #4631. I've been running it on moria1 and it catches and handles real buggy behavior from directory authorities, e.g. Jan 28 15:59:50.804 [warn] Rejecting vote from 199.58.81.140 received at 2020-01-28 20:59:50; our cutoff for received votes is 2020-01-28 20:52:30 Jan 28 15:59:50.805 [warn] Rejected vote from 199.58.81.140 ("Vote received too late, would be dangerous to count it").
