bind9/bin/tests/system/qmin/tests.sh
Diego Fronza 55c0fa2bf6 Added test for the proposed fix 
The test works as follows:

1. Client wants to resolve unusual ip6.arpa. name:

   test1.test2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.9.0.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. IN TXT

2. Query is sent to ns7, a qmin enabled resolver.

3. ns7 do the first stage in query minimization for the name and send a new
   query to root (ns1):

  _.1.0.0.2.ip6.arpa.        IN  A

4. ns1 delegates ip6.arpa. to ns2.good.:

    ;; AUTHORITY SECTION:
    ;ip6.arpa.      20  IN  NS  ns2.good.

    ;; ADDITIONAL SECTION:
    ;ns2.good.      20  IN  A   10.53.0.2

5. ns7 do a second round in minimizing the name and send a new query
   to ns2.good. (10.53.0.2):

   _.8.2.6.0.1.0.0.2.ip6.arpa.    IN  A

6. ans2 delegates 8.2.6.0.1.0.0.2.ip6.arpa. to ns3.good.:

    ;; AUTHORITY SECTION:
    ;8.2.6.0.1.0.0.2.ip6.arpa. 60   IN  NS  ns3.good.

    ;; ADDITIONAL SECTION:
    ;ns3.good.      60  IN  A   10.53.0.3

7. ns7 do a third round in minimizing the name and send a new query to
   ns3.good.:

    _.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. IN A

8. ans3 delegates 1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. to ns4.good.:

    ;; AUTHORITY SECTION:
    ;1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. 60 IN    NS  ns4.good.

    ;; ADDITIONAL SECTION:
    ;ns4.good.      60  IN  A   10.53.0.4

9. ns7 do fourth round in minimizing the name and send a new query to
   ns4.good.:

	_.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa.    IN A

10. ns4.good. doesn't know such name, but answers stating it is authoritative for
    the domai:

	;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id:  53815
	...
	;; AUTHORITY SECTION:
	1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. 60 IN    SOA ns4.good.  ...

11. ns7 do another minimization on name:
   _.9.0.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa
   sends to ns4.good. and gets the same SOA response stated in item #10

12. ns7 do another minimization on name:
	_.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.9.0.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa
	sends to ns4.good. and gets the same SOA response stated in item #10.

13. ns7 do the last query minimization name for the ip6.arpa. QNAME.
	After all IPv6 labels are exausted the algorithm falls back to the
	original QNAME:
	test1.test2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.9.0.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa

    ns7 sends a new query with the original QNAME to ans4.

14. Finally ans4 answers with the expected response:
	;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id:  40969
	;; flags: qr aa; QUESTION: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1
	;; OPT PSEUDOSECTION:
	; EDNS: version: 0, flags:; udp: 8192
	;; QUESTION SECTION:
	;test1.test2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.9.0.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. IN TXT

	;; ANSWER SECTION:
	;test1.test2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.9.0.9.4.1.1.1.1.8.2.6.0.1.0.0.2.ip6.arpa. 1    IN TXT "long_ip6_name"
