Re: Bug in SLP template formation.

Biswapratap,

From DSP0206 :

FunctionalProfilesSupported=string L M
# ProfilesSupported defines the CIM Operation profiles supported by the
# CIM Object Manager. This attribute MUST be the
# CIM_ObjectManagerCommunicationMechansim.FunctionalProfilesSupported 
# property value.
"Unknown", "Other", "Basic Read", "Basic Write",
"Schema Manipulation", "Instance Manipulation",
"Association Traversal", "Query Execution",
"Qualifier Declaration", "Indications"

From the above description, although 
CIM_ObjectManagerCommunicationMechansim.FunctionalProfilesSupported is 
uint16 array, it seems SLP Template requires them in string form.


FunctionalProfileDescriptions=string L O M
# Other profile description if the "other" value is set in the 
ProfilesSupported
# attribute.  This attribute is optional because it is returned only if 
the "other"
# value is set in the ProfilesSupported attribute. If provided it MUST
# be equal to the 
CIM_ObjectManagerCommunicationMechanism.FunctionalProfileDescriptions
# property value.


From the above description FunctionalProfileDescriptions is only required 
if  1 (other) is specified in 
CIM_ObjectManagerCommunicationMechansim.FunctionalProfilesSupported array. 
However it seems confusing specifying that FunctionalProfileDescriptions 
of SLP template is equal to 
CIM_ObjectManagerCommunicationMechanism.FunctionalProfileDescriptions in 
DSP0206.

Bug in SLP template formation.






Hi all,
 
While debugging open-pegasus's inbuilt SLP Provider implementation, I 
found out the following issue - 
 
File Name : $PEGASUS_HOME/src/Providers/slp/SLPProvider.cpp
Method Name : Boolean SLPProvider::populateRegistrationData( ... )
Code Fragment :
 
else if (propertyName.equal("FunctionalProfileDescriptions"))
        {
            Array<String> descriptions;
            v1.get(descriptions);
 
            String desList = _arrayToString(descriptions);
            populateTemplateField(
                templateInstance,
                functionalProfilesSupportedAttribute,
                desList);
 
            if (String::equalNoCase(v1.toString(),"Other"))
            {
                Uint32 pos = instance_ObjMgrComm.findProperty(
 CIMName(otherProfileDescriptionAttribute));
                CIMConstProperty temppr = 
instance_ObjMgrComm.getProperty(pos);
                String tmp = _getPropertyValueString(
                                  instance_ObjMgrComm, 
 CIMName(otherProfileDescriptionAttribute),
                                  String::EMPTY);
                populateTemplateField(
                    templateInstance,
                    otherProfileDescriptionAttribute,
                    tmp);
            }
        }
 
Bug : 
functionalProfilesSupportedAttribute - AttributeFieldName, used to 
populate the template field of the slp registration maps to 
"FunctionalProfilesSupported" property of the 
CIM_ObjectManagerCommunicationMechanism class as found in the following 
initial code framgment of SLPProvider.cpp.
 
const char functionalProfilesSupportedAttribute[] =
               "FunctionalProfilesSupported";
 
But as seen from the first code fragment the propertyName equals "
FunctionalProfileDescriptions" i.e. an optional (non-mandatory) property 
of the CIM_ObjectManagerCommunicationMechanism class. Hence, the 
propertyName fetched and the SLP template attribute propertyname are not 
in sync. There is an appropriate mandatory property - uint16 
FunctionalProfilesSupported[] in CIM_ObjectManagerCommunicationMechanism 
class which should be used, I think.
 
Effect :
Since this property in the template attribute list is filled as "nothing" 
hence, CTP test for SMIS complaint providers is failing for recipes in 
Profile Registration Profile and Server Profile, while parsing the 
attribute list.
