Comment (by teor): This might be related to commit a21381a in 0.2.0.3-alpha, where we disabled the desc_by_eid_map check in routerlist_assert_ok(). If we fix this bug, we should re-enable it with a non-fatal assert. {{{ /* XXXX * * Hoo boy. We need to fix this one, and the fix is a bit tricky, so * commenting this out is just a band-aid. * * The problem is that, although well-behaved router descriptors * should never have the same value for their extra_info_digest, it's * possible for ill-behaved routers to claim whatever they like there. * * The real answer is to trash desc_by_eid_map and instead have * something that indicates for a given extra-info digest we want, * what its download status is. We'll do that as a part of routerlist * refactoring once consensus directories are in. For now, * this rep violation is probably harmless: an adversary can make us * reset our retry count for an extrainfo, but that's not the end * of the world. Changing the representation in 0.2.0.x would just * destabilize the codebase. if (!tor_digest_is_zero(r->cache_info.extra_info_digest)) { signed_descriptor_t *sd3 = sdmap_get(rl->desc_by_eid_map, r->cache_info.extra_info_digest); tor_assert(sd3 == &(r->cache_info)); } */ }}} -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/16016#comment:21> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
