Finally, a significant number of internal changes and corrections were made

under the control of the Pegasus bugzilla bug system. See the bug section below

for more information.

<h3>Information on  IPv6 Support (PEP 291)</h3>

IPv6 is short for "Internet

Protocol

Version 6". IPv6 is the "next generation" protocol designed by the IETF

to replace the current version Internet Protocol, IP Version 4

("IPv4"). IPv6 Support for OpenPegasus is documented in <a

href="http://www.openpegasus.org/pp/uploads/40/14222/PEP_291_IPv6.html">

PEP

291</a>.

The IPv6 support in OpenPegasus is

controlled by the PEGASUS_ENABLE_IPV6 build variable. The default for this

variable is "true"; setting this to

'false' before building OpenPegasus will disable the IPv6 support.

CQL Stage 1 has been added for Pegasus 2.5.  PEPs 138, 193, 205

The following subsections provide

some information on IPv6 support for the Linux and Windows platforms.

Specification.  Embedded instances will also carry the

EmbeddedObject attribute with

the value "object", as specified by CR Interop-00217.001.

</li>

</ul>

<h3>Pegasus Repositories

</h3>

</blockquote>

<h4>Schema Repository</h4>

By default, Pegasus uses an XML-based

schema repository. A binary encoding option is also available for the repository.

Note: Users may experience an incompatibility moving a binary repository from

Pegasus 2.4 to 2.5. In Pegasus 2.5, measures have been taken to improve

the ability to maintain compatibility with subsequent releases. (See bugzilla 3642 for details.)</div>

Further information on the use of the binary repository is in the

readme.binaryrepository file in the Pegasus source root directory.

<h4>Instance Repository</h4>

The

Pegasus schema repository may also be configured to hold instance

data.  Although instances may be place in the

repository

it was not designed as a

high volume data store.

<h4>Compressed Repository Feature</h4>

A compressed repository

feature has been added for

pegasus 2.5 that compresses the repository written to disk. This allows

the

repository to be as much as 50% smaller on disk. It uses an external

compression library (zlib) and has been tested with zlib 1.2.2. This

feature is

documented in PEP 214 and also in a Readme

(readme.compressed_repository). Note

that the tests for this feature are in the test suite but not

activated for

automatic tests.Further information on the use of the compressed

repository is in the readme.compressedrepository file in the Pegasus source

root directory.

<h4>Pegasus MOF Compilers</h4>

Pegasus implements a MOF compiler that can operate either at the

client

interface to the Pegasus CIM Server (cimmof)

or directly interfacing with a CIM

repository (cimmofl).

The direct interface compiler is used primarily to provide an

initial

class/instance repository. WARNING:

The use of cimmofl

to manipulate instances in the repository bypasses any provider that is

registered to serve these  instances and simply installs the

instances in the

instance repository; this may result in 1) bad data in the repository

if there are registered providers, 2) corruption of the repository if

the CIM Server is running or, 3) MOF data that is loaded but not

available until the server is stopped and restarted in some

cases.  Use of cimmofl in general is

discouraged and particularly  to manipulate

instances served by a registered providers (ex. Provider registration).

'Run-as-requestor' (not available prior to Pegasus 2.5) and/or

performing authorization checks within the provider.

b. For administrators, ensure that the providers you have registered in

your environment have performed sufficient authorization checks. Also,

monitor announcements of security defects in those providers and follow

the recommendations in those announcements as soon as possible.

c. For distributors of Pegasus or providers, ensure that the providers

you are shipping have performed appropriate authorization checks, and

relay announcements of discovered security defects to your users.

</div>

2. Restrict users with

access to Pegasus to a specific authorized user group of trusted

individuals.

3. Namespace authorization is also available.

and are the responsibility of the client to implement on their

own.  See the SSL guide found in the /pegasus/doc directory for

more details on client security.

Note: WBEM clients are responsible for SSL

certificate verification using Pegasus and/or SSL libraries as

appropriate. Consequences of not doing so include leakage of

authentication credentials to unauthorized parties.

enable or disable this code.  Effective with Pegasus 2.5.1, support has

been added for the use of OpenSLP as the Service Agent (SA) in addition to the

internal to the Service Agent.  This is controlled through an additional

environment variable (PEGASUS_HAS_OPENSLP)  Once compiled, SLP

support is enabled with the slp configuration parameter (slp=true). SLP

support includes an SLP service agent in the Pegasus CIM sever (either the

internal agent or OpenSLP)  and

generates SLP advertisements compatible with the DMTF slp template

specification. The SLP support also includes  extensions to the

CIM Client libraries to execute SLP User Agent requests and analyze the

results (note that these interfaces are not yet part of the Pegasus

public SDK).

Note: Pegasus on Windows is built with SLP support on by default.

<h4>Pegasus Provider Interfaces</h4>

Pegasus is designed to support multiple Provider Managers to allow

multiple provider interfaces to the CIMOM.  The two default

provider managers are the Pegasus C++ Interface and Common

Manageability Programming Interface (CMPI) Interface.

<h5>C++ Provider Interface</h5>

This is the original

interface defined for OpenPegasus Providers.  It provides an interface

for both operations and indications. Many of the sample and test providers are

written to this interface.  This interface includes a callback into the

CIMOM (CIMOMHandle).

<h5>CMPI C interface Provider Manager<o:p></o:p></h5>

http://www.opengroup.org/bookstore/catalog/c051.htm. This provides a

standardized C level interface for creating providers that can be

registered with the Pegasus CIM Server in the same manner as the

current C++ providers.  The

ability for CMPI providers to do user authorization is now available in

Pegasus 2.5.1.

Information on writing providers with the CMPI interface is available

in the specification today (see above) and in the following documents

(http://sblim.sourceforge.net/whitepaper.html and

http://sblim.sourceforge.net/presentations.html) and readme.cmpi in the

Pegasus source root directory.

NOTE: See the Feature status page

for exact status of the CMPI provider manager for different Pegasus

platforms.

<h5>JMPI Java Interface Provider Manager</h5>

Pegasus

includes a provider manager for Java

provider interfaces based on the SNIA provider interface

definitions.  This provider manager is  considered alpha

quality and is not compiled in the default build.   See

readme.jmpi in the Pegasus source root directory for more information.

<h4>Server Statistics Provider

</h4>

CIM Server statistics, based on the DMTF 'CIM_StatisticalData' class,

are implemented in this release. The statistics gathering is compiled

by default but it is disabled through a property in the singleton

CIM_ObjectManager class. It may be enabled or disabled by performing a

ModifyInstance operation on the 'CIM_ObjectManager instance

in the 'PG_InterOp' namespace to set the GatherStatisticalData property

to 'true' or 'false'. This property setting is persistent across CIM

Server restarts. A statistics display test tool, cimperf, is available

from the Pegasus CVS repository. <h4>SLP Provider</h4>

This provider acts as the definer of

SLP information for SLP registration and also controls the Pegasus SLP

Service Agent. It is treated as a normal provider rather than a control

provider because it does not use internal functions of the CIMOM to

generate any of its information today. (conditionally compiled today)

</blockquote>

<h2>Pegasus Indication Listeners</h2>

The generic components for a CIM Listener and a

listener API are operational.  This includes the functions for

HTTP, XML indication input and response, and consumers of indications.

This code can be used to define a separate listener package and is used

as an indication listener in the Pegasus server.

Pegasus includes 3 separate Indication Listeners.

<h3>Embedded CIMListener</h3>

This listener is embedded in the CIMServer and allows the

server to accept indications and route them.

<h3>Standalone Static CIMListener</h3>

This is a standalone listener that combines the functions

of listener and consumer into a single element.

<h3>Standalone Dynamic Listener</h3>

Pegasus 2.5

includes a new standalone dynamic listener that is separate

from the current standalone CIMListener and the ExportServer listener

in the CIM server.

The use model that this listener fits is the following:

<ul>

<li> The listener may be packaged as

part of the CIMOM or it may be packaged independently as part of

another application. </li>

<li> Consumers

are developed independently of the listener and may be shipped with the

listener or added to an installed listener at a future time. </li>

</ul>

This

dynamic listener provides a solution for the above use model. It

is essentially a lightweight, pluggable listener that

provides a small set of management features. The DynamicListener can be

run inside a daemon or a service. It is easily configurable and

bypasses traditional registration procedures.  See

<a href="http://www.openpegasus.org/pp/protected/upreviews/20/1303/PEP195_CIMListenerEnhancementsv1_6.htm" style="color: blue; text-decoration: underline;">PEP 195</a>  for

details.

</blockquote>

<h3>CIM_Schema</h3>

The default CIM_Schema loaded with this

release is

the DMTF CIM 2.9, final release.  In addition, Pegasus includes

a number of

local classes defined for Pegasus.  These are defined in the pegasus/Schemas

directory.   There are also a

number of older schema available in the CVS.  Further, the CIM 2.10 and CIM

2.11 schemas are available in the CVS repository and the Pegasus is compatible

with these Schemas.

The mechanism to install other schemas than the default is defined

in the mak/config.mak

NOTE: The CIM 2.5 schema is

maintained in the

CVS repository because it remains the basis for parts of the Pegasus

test

environment.

<h3>Pegasus Interface APIs</h3>

Details of the Pegasus public interfaces for this release are listed

in PEP 209

available from the web site(<a href="http://www.openpegasus.org/pp/uploads/40/Administrator/My%20Documents/processes/www.openpegasus.org">www.openpegasus.org</a>).

That document is the authorative source for the list

of publicly supported Pegasus APIs.   The Client and Provider API were

originally frozen at the Pegasus version 2.1 release. The interfaces in the

release of Pegasus 2.1 are forward compatible to this release. Well-behaved

clients and providers compiled to the Pegasus 2.1 or 2.2 interfaces should be

compatible with this release without compilation.  There have been

extensions and new interfaces added for this release.

  The Pegasus public

interfaces includes the following major functions

<li class="MsoNormal" style="color: black;">Client APIs<o:p></o:p></li>

<li class="MsoNormal" style="color: black;">Provider APIs<o:p></o:p></li>

<li class="MsoNormal" style="color: black;">CIM Object and System

function APIs</li>

</ol>

In addition, there are other client interfaces which are not today

in the public SDK including:

<li class="MsoNormal" style="color: rgb(0, 0, 0);">CIM Listener APIs</li>

<li class="MsoNormal">CIM Listener

is a component that can be used to consume indications without a

dependency on the Pegasus CIMOM. In environments where no CIMOM is

running or a physical separation between the indication listener and

the CIMOM is desired, CIM Listener fits the bill. Still, there are

several enhancements that are necessary to make CIM Listener scalable. Enhancements were deemed significant

enough to propose a new listener that builds off CIMListener's

basic capabilities, yet allows the existing CIMListener to remain the

same.</li>

WMI Mapper

The WBEM to WMI Mapper provides a way

to access

WMI data from Windows platform systems. It converts incoming XML/CIM

requests

to Microsoft WMI requests, executes the requests, converts the results

XML/CIM and returns the results to the client. WMI Mapper

receives an HTTP message containing the XML/CIM request. It decodes the

XML

message and extracts from the HTTP message header the user credentials

provided

on the connection (username and password). The WMI Mapper

authenticates these credentials, verifying if the provided credentials

have

access to the desired WMI data. This is done because the WMI Mapper runs as a service, logged on using an

account with

administrative rights (which has all access to WMI data). Because of

this, the

WMI Mapper impersonates the user

credentials provided

on the HTTP message to ensure that the calling user has rights to

browse WMI

data. Hence, ALL requests made to the WMI Mapper

MUST

contain user credentials.

<h2><a name="Compatibility_Considerations_">Compatibility Considerations</a></h2>

Support for forward-compatibility is a fundamental design principle for the

OpenPegasus project. As a Community, our goal is for well-behaved OpenPegasus

Providers or Clients, using only the externally defined OpenPegasus interface,

to continue to work with a minor version upgrade of OpenPegasus. However, there

are certain classes of errors (e.g., non-compliance with a standard that

significantly affects interoperability) that may require the Community to make

potentially incompatible changes. The following table contains a list of defect

fixes that MAY impact, even well-behaved, OpenPegasus Providers or Clients when

Exceptions to

DMTF Specifications</a></h2>

It is a major goal

of the OpenPegasus project to both drive and utilize the DMTF CIM/WBEM

specifications.  However, today there are a number of known

differences. 

As of this release, some of the differences include the following:

<ol>

<li>Provider Registration - Pegasus supports registration

through a set of Pegasus Provider registration classes rather than

support the DMTF defined Provider Qualifier. Pegasus will not support

this qualifier in the future. See the readme for more information on

provider registration.  This is not a deviation from the

specifications but is a different method of registration than many CIM

Servers and means that the the provider qualifier is unused in Pegasus.</li>

<li>Indications -Today Pegasus supports process

indications and lifecycle indications when defined specifically by

providers. Pegasus does not support lifecycle indications if they are

not defined by the provider or for changes to CIM Classes.<font

color="#ff0000">  For

more information see the Pegasus CVS file:<a name="comtag_137">

face="Courier New" size="2"> pegasus/src/Unsupported/LifecycleIndicationProvider/README.LifecycleIndications.htm</a>.</li>

<li>

<font

style="color: rgb(0, 0, 0); font-weight: bold;">IncludeQualifiers

option on Instance Operations

The DMTF specifications have deprecated the use of qualifiers on

instance operations with the 1.2 CIM Operations Specification. 

Some CIM Client implementations expect instances

returned

from the CIM Server to include the qualifiers defined in the class

definition (such as KEY qualifiers on properties).   Pegasus

today expects the provider to complete the qualifiers on instances in

accordance with the specification and generally the interpretation is

that Pegasus applies class level qualifiers when the includeInstance

parameter is supplied on instance operations.  However, Pegasus

today is inconsistent in the return of qualifiers so that the user

should NOT depend on Pegasus accurately honoring the includeQualifier

parameter for instance operations.  In the future it is expected

that Pegasus will deprecate the use of qualifiers on instance

operations completely.

</li>

<li>LocalOnly option on instance

Operations - With the 1.1 version of Specification for CIM

Operations over HTTP, the definition of the LocalOnly parameter for the

GetInstance and Enumerate Instances operations was modified. This change

was incorrect, resulted in reduced functionality and introduced a

number of backward compatibility issues. As a result of issues

introduced by this change, we strongly recommend that CIM Clients set

LocalOnly = false and do not rely on the use of this parameter to

filter the set of set of properties returned. See Appendix C of this

specification for more information.</li>

<li>

MultiRequest Operations - Pegasus

does not support the DMTF defined MultiRequest Operation option.

</li>

<li>

MOF Compiler namespace pragma - The

Pegasus compiler does not support the namespace pragma.

<h2><a name="Conformance with DMTF Specifications">Conformance with

DMTF Specifications</a></h2>

It is a major goal

of the OpenPegasus project to both drive and utilize the DMTF CIM/WBEM

specifications.  However, today there are a number of known

differences. 

As of this release, some of the differences include the following:

<ol>

<li>Provider Registration - Pegasus supports registration

through a set of Pegasus Provider registration classes rather than

support the DMTF defined Provider Qualifier. Pegasus will not support

this qualifier in the future. See the readme for more information on

provider registration.</li>

<li> Indications -Today Pegasus supports process

indications but does not

include any specific support for lifecycle indications.</li>
