From: Michał Kępień Date: Mon, 29 Jul 2019 19:44:31 +0000 (+0200) Subject: Make root hints consistent with authoritative data X-Git-Tag: v9.15.3~27^2 X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=c19ebde14bb64739d01670170f76d2cc3d2e2a29;p=thirdparty%2Fbind9.git Make root hints consistent with authoritative data Resolvers in the "filter-aaaa" system test are configured with a single root hint: "ns.rootservers.net", pointing to 10.53.0.1. However, querying ns1 for "ns.rootservers.net" results in NXDOMAIN answers. Since the TTL for the root hint is set to 0, it may happen that a resolver's ADB will be asked to return any known addresses for "ns.rootservers.net", but it will only have access to a cached NXDOMAIN answer for that name and an expired root hint, which will result in a resolution failure, triggering a false positive for the "filter-aaaa" system test. Prevent this from happening by making all the root hints consistent with authoritative data served by ns1. --- diff --git a/bin/tests/system/filter-aaaa/ns2/hints b/bin/tests/system/filter-aaaa/ns2/hints index 381e86b1522..fbf01a93698 100644 --- a/bin/tests/system/filter-aaaa/ns2/hints +++ b/bin/tests/system/filter-aaaa/ns2/hints @@ -7,5 +7,8 @@ ; See the COPYRIGHT file distributed with this work for additional ; information regarding copyright ownership. -. 0 NS ns.rootservers.utld. -ns.rootservers.utld. 0 A 10.53.0.1 +$TTL 120 + +.
