commit eae68fa2d2bde931bf8b9115f7a9cb7a0f0c9073 Author: Philipp Winter <phw@nymity.ch> Date: Wed Jul 27 12:01:03 2016 -0400 Initialise DNS TTL for A and AAAA records. So far, the TTLs for both A and AAAA records were not initialised, resulting in exit relays sending back the value 60 to Tor clients. This also impacts exit relays' DNS cache -- the expiry time for all domains is set to 60. This fixes <https://bugs.torproject.org/19025>. --- src/or/dns.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/or/dns.c b/src/or/dns.c index 41a6dfd0a..e007a402f 100644 --- a/src/or/dns.c +++ b/src/or/dns.c @@ -326,7 +326,7 @@ cached_resolve_add_answer(cached_resolve_t *resolve, resolve->result_ipv4.err_ipv4 = dns_result; resolve->res_status_ipv4 = RES_STATUS_DONE_ERR; } - + resolve->ttl_ipv4 = ttl; } else if (query_type == DNS_IPv6_AAAA) { if (resolve->res_status_ipv6 != RES_STATUS_INFLIGHT) return; @@ -341,6 +341,7 @@ cached_resolve_add_answer(cached_resolve_t *resolve, resolve->result_ipv6.err_ipv6 = dns_result; resolve->res_status_ipv6 = RES_STATUS_DONE_ERR; } + resolve->ttl_ipv6 = ttl; } }
