Hideshi, I think your modifications are correct.  Can you please email me the.seq files once they have been updated?

I will fix these problem as soon as possible.	 	But I think that following correction is enough for the testpurpose.

The function options_exist() that is defined inDHCP_common.pm has two possible return values: 0 and 1.		It will return 0 if all of the options exist.		It will return 1 if any of the options do not exist.		 		Taking C_RFC3646_5_InvDecDnsSvrOpt.seq as an example, itcalls options_exist() with ($CMP_CID|$CMP_DNS_SVR).		This will return with a 0 (and therefore cause the testto fail) only if both of these options exist, if only one of the optionsis present then this will return with a 1 (and the test will stillpass).  I believe this to be incorrect.  If either of these options ispresent the test should fail.		 		Also, with C_RFC3646_5_InvDecDnsSvrOpt.seq, checking forthe presence of a Client Identifier option is incorrect.  From RFC3315,a Decline message MUST be discarded by a server if it does not include aClient Identifier option.		 		Finally, with C_RFC3646_5_InvDecDnsSchLstOpt.seq, Ibelieve that it should check not only for $CMP_DNS_LST but also for$CMP_DNS_SVR as well.		 		Because testing for this is based on logic that requiresa failure if any of the options do exist (which is different from thereturn values of options_exist() when called with multiple options) itis required that you call the options_exist() function one time for eachoption you are checking for.		 		Here is how I believe it should look:		 		C_RFC3646_5_InvDecDnsSchLstOpt.seq:		$ret = options_exist(\%dec, ($CMP_DNS_LST));		if ($ret != 0) {		    $ret = options_exist(\%dec, ($CMP_DNS_SVR));		}		if($ret == 0){		        vLogHTML('<FONT COLOR="#FF0000">DHCPv6 Clientshould not send Decline with Domain Search List option and/or DNSRecursive Name Server option!</FONT><BR>');		        dhcpExitFail;		}		 		 		C_RFC3646_5_InvDecDnsSvrOpt.seq: (note the removal of$CMP_CID)		$ret = options_exist(\%dec, ($CMP_DNS_LST));		if ($ret != 0) {		    $ret = options_exist(\%dec, ($CMP_DNS_SVR));		}		if($ret == 0){		        vLogHTML('<FONT COLOR="#FF0000">DHCPv6 Clientshould not send Decline with Domain Search List option and/or DNSRecursive Name Server option!</FONT><BR>');		        dhcpExitFail;		}		 		 		Please let me know your thoughts.

The problem is that our client device does includeoptions 23 and 24 in its Decline packets - and yet the Tahi Testsreports that they "PASS" these tests.  I would expect our product tofail these tests.

But, these tests that you mentioned are correct, Ithink.				These tests focus on following statements in RFC 3646.				----------------------------		5.  Appearance of these options				   The DNS Recursive Name Server option MUST NOT appearin any other		   than the following messages: Solicit, Advertise,Request, Renew,		   Rebind, Information-Request, and Reply.				   The Domain Search List option MUST NOT appear in anyother than the		   following messages: Solicit, Advertise, Request,Renew, Rebind,		   Information-Request, and Reply.		----------------------------				So, these tests really expect that the message does notinclude DNS		Recursive Name Server option/Domain Search List option.				regards,		...Hideshi		________________________________				        From: Scott Langley[mailto:slangley@tadboise.com]		        Sent: Wednesday, June 06, 2007 2:17 AM		        To: Enokihara, Hideshi(Hideshi.Enokihara@jp.yokogawa.com)		        Cc: dhcptest@tahi.org		        Subject: RE: FW: [dhcptest:00173] Re: Tests thatcheck for DNS		and Domain Search Options		       		       				        Hi Hideshi,		       		        The revised files you sent do appear to workproperly.		       		        However, I think there are a few more tests thathave problems.		       		        These two test pass, even though our DECLINEmessages include		both options 23 and 24:		       		         C_RFC3646_5_InvDecDnsSchLstOpt.seq		         C_RFC3646_5_InvDecDnsSvrOpt.seq		       		        I suspect that the options_exist() method ofDHCPv6_common.pm		may be flawed.		       		        These four other tests, below, are similarlywritten, but I		can't say if there is anything wrong with them becauseour product		doesn't yet send CONFIRM and RELEASE messages when itshould:		       		         C_RFC3646_5_InvCnfDnsSchLstOpt.seq		         C_RFC3646_5_InvCnfDnsSvrOpt.seq		         C_RFC3646_5_InvRelDnsSchLstOpt.seq		         C_RFC3646_5_InvRelDnsSvrOpt.seq		       		        Thanks.		       		        --		        Scott Langley		        Adecco Technical		        slangley@tadboise.com		       		       		        -----Original Message-----		        From: Hideshi Enokihara		[mailto:Hideshi.Enokihara@jp.yokogawa.com]		        Sent: Mon 6/4/2007 7:15 PM		        To: Scott Langley		        Cc: dhcptest@tahi.org		        Subject: Re: FW: [dhcptest:00173] Re: Tests thatcheck for DNS		and Domain Search Options		       		        Hello Scott,		       		        Thank you for your report.
