Hi Hideshi,Talking about this with Peter, we agreed that we were interpreting the =intent of this test differently:I was interpreting the prohibition of the appearance of the DNS =recursive name server option and the Domain Search List options as =applying to the option request section and not to actual returned =options. My interpretation is probably wrong.The purpose of the tests is probably to make sure that the DECLINE =packets don't include actual DNS recursive name server and Domain Search =List options.  Is that correct?Scott-----Original Message-----From: Hideshi.Enokihara@jp.yokogawa.com =[mailto:Hideshi.Enokihara@jp.yokogawa.com]Sent: Sun 6/17/2007 10:30 PMTo: pcarney@treck.comCc: dhcptest@tahi.orgSubject: [dhcptest:00184] Re: FW:  Re: Tests that check for DNS and =Domain Search Options Hello Peter,Actually, I have not added any modification to =C_RFC3646_5_InvDecDnsSchLstOpt.seq.I have modified only for C_RFC3646_5_InvDecDnsSvrOpt.seq.Could you verify these behavoirs, please?Thanks,-----Original Message-----From: Peter Carney [mailto:pcarney@treck.com]Sent: 2007/06/15 (?) 21:17To: Enokihara, Hideshi (Hideshi.Enokihara@jp.yokogawa.com)Cc: dhcptest@tahi.orgSubject: RE: [dhcptest:00180] Re: FW:  Re: Tests that check for DNS and =Domain Search Options Hideshi, I think your modifications are correct.

The function options_exist() that is defined in DHCP_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, it calls =options_exist() with ($CMP_CID|$CMP_DNS_SVR).		This will return with a 0 (and therefore cause the test to fail) only =if both of these options exist, if only one of the options is present =then this will return with a 1 (and the test will still pass).  I =believe this to be incorrect.  If either of these options is present the =test should fail.		 		Also, with C_RFC3646_5_InvDecDnsSvrOpt.seq, checking for the presence =of a Client Identifier option is incorrect.  From RFC3315, a Decline =message MUST be discarded by a server if it does not include a Client =Identifier option.		 		Finally, with C_RFC3646_5_InvDecDnsSchLstOpt.seq, I believe 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 requires a failure if =any of the options do exist (which is different from the return values =of options_exist() when called with multiple options) it is required =that you call the options_exist() function one time for each option 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 Client should not =send Decline with Domain Search List option and/or DNS Recursive 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 Client should not =send Decline with Domain Search List option and/or DNS Recursive Name =Server option!</FONT><BR>');		        dhcpExitFail;		}		 		 		Please let me know your thoughts.

However, I think there are a few more tests that have =problems.
