From 094e416fff2c2c2d0f0d83d4201860e52e65d0ac Mon Sep 17 00:00:00 2001 From: Aram Sargsyan <aram@isc.org> Date: Wed, 29 Dec 2021 09:07:03 +0000 Subject: [PATCH] Add a system test for view reverting after a failed reconfiguration Test the view reverting code by introducing a faulty dlz configuration in named.conf and using `rndc reconfig` to check if named handles the situation correctly. We use "dlz" because the dlz processing code is located in an ideal place in the view configuration function for the test to cover the view reverting code. This test is specifically added to the catz system test to additionally cover the catz reconfiguration during the mentioned failed reconfiguration attempt. (cherry picked from commit 62337d433f233506d340acdedb7d46bdc0dd662f) Conflict: NA Reference: https://gitlab.isc.org/isc-projects/bind9/-/commit/094e416fff2c2c2d0f0d83d4201860e52e65d0ac --- bin/tests/system/catz/ns2/named1.conf.in | 8 ++++++++ bin/tests/system/catz/tests.sh | 24 ++++++++++++++++++++++++ 2 files changed, 32 insertions(+) diff --git a/bin/tests/system/catz/ns2/named1.conf.in b/bin/tests/system/catz/ns2/named1.conf.in index 7c5f8c2835..8519802bb0 100644 --- a/bin/tests/system/catz/ns2/named1.conf.in +++ b/bin/tests/system/catz/ns2/named1.conf.in @@ -46,6 +46,14 @@ options { }; }; +# A faulty dlz configuration to check if named and catz survive a certain class +# of failed configuration attempts (see GL#3060). +# We use "dlz" because the dlz processing code is located in an ideal place in +# the view configuration function for the test to cover the view reverting code. +#T3dlz "bad-dlz" { +#T3 database "dlopen bad-dlz.so example.org"; +#T3}; + zone "catalog1.example" { type secondary; file "catalog1.example.db"; diff --git a/bin/tests/system/catz/tests.sh b/bin/tests/system/catz/tests.sh index f217103d8f..2f50740374 100644 --- a/bin/tests/system/catz/tests.sh +++ b/bin/tests/system/catz/tests.sh @@ -370,6 +370,30 @@ wait_for_soa @10.53.0.2 dom3.example. dig.out.test$n || ret=1 if [ $ret -ne 0 ]; then echo_i "failed"; fi status=$((status+ret)) +n=$((n+1)) +echo_i "reconfiguring secondary - checking if catz survives a certain class of failed reconfiguration attempts ($n)" +ret=0 +sed -e "s/^#T3//" < ns2/named1.conf.in > ns2/named.conf.tmp +copy_setports ns2/named.conf.tmp ns2/named.conf +$RNDC -c ../common/rndc.conf -s 10.53.0.2 -p "${CONTROLPORT}" reconfig > /dev/null 2>&1 && ret=1 +if [ $ret -ne 0 ]; then echo_i "failed"; fi +status=$((status+ret)) + +n=$((n+1)) +echo_i "checking again that dom3.example. is served by secondary ($n)" +ret=0 +wait_for_soa @10.53.0.2 dom3.example. dig.out.test$n || ret=1 +if [ $ret -ne 0 ]; then echo_i "failed"; fi +status=$((status+ret)) + +n=$((n+1)) +echo_i "reconfiguring secondary - reverting the bad configuration ($n)" +ret=0 +copy_setports ns2/named1.conf.in ns2/named.conf +rndccmd 10.53.0.2 reconfig || ret=1 +if [ $ret -ne 0 ]; then echo_i "failed"; fi +status=$((status+ret)) + n=$((n+1)) echo_i "removing all records from catalog1 zone ($n)" ret=0 -- 2.23.0
