From a14efdf54cc09165093f2938cafe32a331574a4d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20K=C4=99pie=C5=84?= Date: Fri, 16 Jul 2021 07:20:15 +0200 Subject: [PATCH] Extend tests for signed, CNAME-sourced delegations Extend the "chain" system test with AUTHORITY section checks for signed, secure delegations. This complements the checks for signed, insecure delegations added by commit 26ec4b9a89720e6d5630ad8cf5da6fe357dee32a. Extend the existing AUTHORITY section checks for signed, insecure delegations to ensure nonexistence of DS RRsets in such responses. Adjust comments accordingly. Ensure dig failures cause the "chain" system test to fail. --- bin/tests/system/chain/ns2/named.conf.in | 5 + bin/tests/system/chain/ns2/sign.sh | 8 ++ bin/tests/system/chain/ns2/wildcard-secure.db | 27 +++++ bin/tests/system/chain/tests.sh | 101 +++++++++++++----- 4 files changed, 114 insertions(+), 27 deletions(-) create mode 100644 bin/tests/system/chain/ns2/wildcard-secure.db diff --git a/bin/tests/system/chain/ns2/named.conf.in b/bin/tests/system/chain/ns2/named.conf.in index e8882dc666..dea26feb4d 100644 --- a/bin/tests/system/chain/ns2/named.conf.in +++ b/bin/tests/system/chain/ns2/named.conf.in @@ -40,6 +40,11 @@ zone "signed-sub2.example" { file "sub.db"; }; +zone "wildcard-secure.example" { + type primary; + file "wildcard-secure.example.db.signed"; +}; + zone "wildcard-nsec.example" { type primary; file "wildcard-nsec.example.db.signed"; diff --git a/bin/tests/system/chain/ns2/sign.sh b/bin/tests/system/chain/ns2/sign.sh index d0aa9bb673..db8dc1e2d0 100644 --- a/bin/tests/system/chain/ns2/sign.sh +++ b/bin/tests/system/chain/ns2/sign.sh @@ -19,6 +19,14 @@ ksk=`$KEYGEN -q -a RSASHA256 -b 2048 -fk $zone` zsk=`$KEYGEN -q -a RSASHA256 -b 1024 $zone` $SIGNER -S -o $zone -f $signedfile $zonefile > /dev/null +zone=wildcard-secure.example. +zonefile=wildcard-secure.db +signedfile=wildcard-secure.example.db.signed + +ksk=`$KEYGEN -q -a RSASHA256 -b 2048 -fk $zone` +zsk=`$KEYGEN -q -a RSASHA256 -b 1024 $zone` +$SIGNER -S -o $zone -f $signedfile $zonefile > /dev/null + zone=wildcard-nsec.example. zonefile=wildcard.db signedfile=wildcard-nsec.example.db.signed diff --git a/bin/tests/system/chain/ns2/wildcard-secure.db b/bin/tests/system/chain/ns2/wildcard-secure.db new file mode 100644 index 0000000000..7aa59671cf --- /dev/null +++ b/bin/tests/system/chain/ns2/wildcard-secure.db @@ -0,0 +1,27 @@ +; Copyright (C) Internet Systems Consortium, Inc.
