<h2><span style="color: black;">Functionality of This Release</span></h2>
Pegasus overall status by release is defined by a
<a href="http://www.openpegasus.org/page.tpl?ggid=799">Feature Status WEB Page</a>
that is available on the OpenPegasus web site . That
web page shows the Pegasus users and developers
the status of the various features found in Pegasus using a simple color coded
key (white, red, yellow, green). Pegasus 2.5.1 is a minor release, extending Pegasus 2.5.0 in selected
areas primarily for bug fixes. However, there were some signification
changes in the feature status for selected functions in 2.5.1 (moving selected
functions closer to production-capable status).<p>The following paragraphs list the functionality in this release. In many cases these features and interfaces
are conditionally compiled with special environment variables. <span style="color: rgb(51, 102, 255);"><span style="text-decoration: underline;">

today does not support the ExecuteQuery operation defined as the Query
operation for CQL.<br>
</li>
</ol>

<blockquote>
<h4><b>Indication Processing</b></h4>
<ol>
<li>Process indications - Process indications are operational in
the
Server. This includes support
for subscriptions, filters, and indication handlers, the provider API
for
indications and the CIMXML indication handler.</li>
<li>Lifecycle indications - With the support for embedded objects,
lifecycle indications (ie. those
classes of indications derived from CIM_ClassIndication and
CIM_InstIndication) can now be created. Pegasus 2.5 provides some
enablement for the generation of lifecycle indications. For more
details, refer to
<src/Unsupported/LifecycleIndicationProvider/readme.LifecycleIndications.htm>.</li>
</ol>
<h4><b>Query Language</b></h4>
<p>Pegasus includes the WQL query language which is implemented and
used for filters and in version 2.4 for execQuery. <br>
</p>
<p>CQL Stage 1 has been added for Pegasus 2.5. PEPs 138, 193, 205
combine to describe the CQL functionality supported.</p>
<h4>Object Normalization</h4>
The Object Normalizer is an entity introduced in Pegasus 2.4 that
ensures
objects delivered from providers are complete and accurate. Two major
issues were identified with the initial implementation: 1) the Object
Normalizer droped instances it considered bad, and 2) the Object
Normalizer code slowed performance. These issues are now addressed by
moving the Object Normalizer from the Dispatcher to the Response
Handler (or equivalent) and optimizing the existing implementation. The
move allows errors to be reported to the provider at the point of
delivery and ensures that only a single copy is made to preserve the
CIMOM/provider boundary.<br>
<h4>Embedded Object Support</h4>
Pegasus 2.5 provides embedded object support. The proposed solution
is restricted to the following:<ul>
<li>The only representation for embedded objects supported by this
PEP is CIM-XML (i.e. id does not support MOF encoded objects). </li>
<li>CIMObject is implemented as a new CIMValue type. This type will be used
internally to represent embedded objects. When externalized (via
CIM-XML) these objects will be converted to strings representing valid
INSTANCE or CLASS elements, in accordance with the CIM Infrastructure
Specification. Embedded instances will also carry the
EmbeddedObject attribute with
the value "object", as specified by CR Interop-00217.001.
</li>
</ul>

<div class="Section1">
<blockquote>
<h4><b>Schema Repository</b></h4>
<p style="margin-top: 0pt; margin-bottom: 0pt;">By default, Pegasus uses an XML-based
schema repository. A binary encoding option is also available for the repository.<span style="font-family: "times new roman";"><br>

<h4><b><b>Compressed Repository Feature</b></b></h4>
<span class="norm"></span><font style="color: rgb(0, 0, 0);" color="RED">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

repository is in the readme.compressedrepository file in the Pegasus source
root directory<span style="color: rgb(51, 102, 255);">.</span></p>
<h4><b>Pegasus MOF Compilers</b></h4>
<p>Pegasus implements a MOF compiler that can operate either at the
client
interface to the Pegasus CIM Server (<span class="SpellE">cimmof</span>)
or directly interfacing with a CIM
repository (<span class="SpellE">cimmofl</span>).</p>
<p>The direct interface compiler is used primarily to provide an
initial
class/instance repository. <font color="#ff0000"><b>WARNING:</b></font>
The use of <span class="SpellE">cimmofl</span>
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 <span class="SpellE">cimmofl in general is
discouraged and particularly </span> to manipulate
instances served by a registered providers (ex. Provider registration).

<h3><b><b>Security Considerations</b></b></h3>
<font style="color: rgb(0, 0, 0);" color="RED">OpenPegasus 2.5 (and
prior versions) contains several mechanisms to perform authorization, but none
of these authorization checks are performed by default.
By registering any provider which fails to do appropriate authorization
checks, the consequences may include information leakage, data
corruption, or unintended elevation of privilege. Please ensure that
one of the following mechanisms is used to ensure appropriate access to
your systems and data:</font><p style="margin-bottom: 0pt;">
<font style="color: rgb(0, 0, 0);" color="RED">1. Only install/register providers which perform authorization
appropriate for your environment.</font></p>
<div style="margin-left: 40px;"><font style="color: rgb(0, 0, 0);" color="RED">a. For providers, this may include registering to
'Run-as-requestor' (not available prior to Pegasus 2.5) and/or
performing authorization checks within the provider.<br>
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. <br>
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.</font><br>
</div>
<font style="color: rgb(0, 0, 0);" color="RED">2. Restrict users with
access to Pegasus to a specific authorized user group of trusted
individuals.<br>
3. Namespace authorization is also available.<br>

<h4><b>SLP Discovery</b></h4>
<p>SLP support is included but is conditionally compiled in or out on
a platform basis. <a href="http://www.openpegasus.org/pp/uploads/40/8502/PEP200_RecommendedReleaseOptions.htm">
PEP 237</a> describes the environment variable (PEGASUS_ENABLE_SLP) to
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).<br>
Note: Pegasus on Windows is built with SLP support on by default.</p>
<h4><b>Indication Handlers</b></h4>
<blockquote>
<h5>System Log Indication Handler<br>
</h5>
<p>The SysLog Indication Handler is a new
for 2.5
type of Indication Handler which allows CIM Indications to be delivered
to the system syslog file. It has following features:<br>
</p>
<p>Each syslog file entry has a tag 'CIM Indication' to distinguish
an entry made by Syslog Indication Handler.</p>
<p>If a subscriber includes PerceivedSeverity property in the SELECT
list of the filter condition for the indication, the PerceivedSeverity
will be mapped to syslog error severity. Otherwise, syslog error
severity 'LOG_INFO' is used.</p>

</blockquote>
<h4>Pegasus Provider Interfaces</h4>
<p>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.</p>
<blockquote>
<h5>C++ Provider Interface</h5>
<p class="norm"><font face="Times New Roman" size="3">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).</font><br>
</p>
<h5><b style="">CMPI C interface Provider Manager<o:p></o:p></b></h5>
<span style="font-family: "times new roman";">Pegasus 2.5 includes
a provider manager for the CMPI C interfaces. This C interface is the
result of a project by the IBM SBLIM team (see
http://sblim.sourceforge.net) and is written to the Common
Manageability Programming Interface, which is an OpenGroup standard.
The CMPI
specification is available at:
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. </span><span style="font-family: "times new roman";"><span class="norm"></span></span>The
ability for CMPI providers to do user authorization is now available in
Pegasus 2.5.1.<br>
<span style="font-family: "times new roman";"> <br>
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.</span><p>
<span style="font-family: times new roman;">NOTE: See the Feature status page
for exact status of the CMPI provider manager for different Pegasus
platforms.</span><br>
</p>
<h5>JMPI Java Interface Provider Manager</h5>
<p>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.</p>
</blockquote>
</blockquote>
<h3><b> Providers</b></h3>
<div style="margin-left: 40px;">New for 2.5 is the ability of Providers
to run out of process at
request user- level and running CMPI providers remotely or out of
process space.<br>
<br>
<span class="norm"></span>Administrators should check the providers to
ensure that the provider vendor
has made use of available authorization capability.<br>
</div>
<p style="margin-left: 40px;">There are a number of providers available
in the Pegasus release.
This includes providers in the following categories:</p>
<blockquote style="margin-top: 5pt; margin-bottom: 5pt;">
<h4>Pegasus Internal Providers</h4>
<p>Pegasus provides a set of "internal" providers that have direct
access to the CIMOM for information and provide information and
services to support the CIMOM and its administration. The
providers in this category are mostly defined in the directory
src/pegasus/controlproviders and include support for the following
classes:</p>
<ul>
<li>DMTF Interop classes including __Namespace, <span class="SpellE">CIM_Namespace</span>, <span class="SpellE">CIM_ObjectManager</span>,
<span class="SpellE">CIM_CommunicationMechanism, and
CIMOMStatistics.</span></li>
</ul>
<h4><span class="SpellE">CMPI Remote Providers</span></h4>
<span class="SpellE">Pegasus includes an support for
running CMPI providers to be run on remote systems without the need for
an extra CIMOM. It uses a special proxying provider to relay requests
to a remote location using so-called communication layers. The remote
side has to start a CMPIRDaemon process, which accepts remote requests
and passes them on to CMPI style providers.</span><h3>
<b>Generic Providers</b></h3>
<p>These are providers that support multiple pegauss platforms and include the Generic <span class="SpellE">OperatingSystem</span> provider. See
the
directory <span class="SpellE">src</span>/Providers/generic.</p>
<h4><b>Test/Sample Providers</b></h4>
<p>See the directories <span class="SpellE">src/Providers/TestProviders</span>
and <span class="SpellE">src</span>/Providers/sample for more
information about test and
sample providers.</p>
<h4><b>Managed System Providers</b></h4>
<p><span class="SpellE">ComputerSystem</span>, <span class="SpellE">DNSAdmin</span>,
<span class="SpellE">DNSService</span>, Operating System, Process,
Processor. For
more information on these providers see the documentation for each
provider in
the directory <span class="SpellE">src/Providers/ManagedSystem</span></p>
<h4><span class="SpellE">Server Statistics Provider<br>
</span></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><span class="SpellE">SLP Provider</span></h4>
<p><span class="SpellE">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)</span></p>

<h2><b>Pegasus Indication Listeners</b></h2>
<blockquote style="margin-top: 5pt; margin-bottom: 5pt;">
<p class="MsoNormal">The generic components for a CIM Listener and a
listener API are operational. This includes the functions for

</p>
<p class="MsoNormal">Pegasus includes 3 separate Indication Listeners.</p>
<h3>Embedded CIMListener</h3>
<p class="MsoNormal">This listener is embedded in the CIMServer and allows the
server to accept indications and route them.</p>

<h3><span class="SpellE"><b>CIM_Schema</b></span></h3>
<blockquote>
<p>The default <span class="SpellE">CIM_Schema</span> loaded with this

That document is the <span class="SpellE">authorative</span> 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</p>
<ol style="margin-top: 0in;" start="1" type="1">
<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>
<p>In addition, there are other client interfaces which are not today
in the public SDK including:</p>
<ol style="margin-top: 0in;" start="1" type="1">
<li class="MsoNormal" style="color: rgb(0, 0, 0);"><span style="" lang="DA">CIM Listener APIs</span></li>
<ul style="color: rgb(0, 0, 0);">
<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. <font style="color: rgb(0, 0, 0);">Enhancements were deemed significant

<p>The WBEM to WMI <span class="SpellE">Mapper</span> 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
to
XML/CIM and returns the results to the client. WMI <span class="SpellE">Mapper</span>
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 <span class="SpellE">Mapper</span>
authenticates these credentials, verifying if the provided credentials
have
access to the desired WMI data. This is done because the WMI <span class="SpellE">Mapper</span> runs as a service, logged on using an
account with
administrative rights (which has all access to WMI data). Because of
this, the
WMI <span class="SpellE">Mapper</span> 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 <span class="SpellE">Mapper</span>
MUST
contain user credentials.<br>

<p>Each Pegasus release lists as 'active' platforms those
hardware/software platforms that have recognized ports for the Pegasus
code
base including a maintainer for the platform that will be willing to
regularly document issues and/or fix defects as the Pegasus
code base is changed.
Pegasus may be operable on other platforms (ex. Windows 98) but without
a group
to provide the role of test and maintenance, correct operation of
Pegasus cannot be
assured. In all cases, including the active platforms, it is the
responsibility of the entity that packages and/or compiles OpenPegasus
for shipment or deployment, to read, and actively monitor the Pegasus
bugzilla database for a list of relevant defects that affect their
platform. The platforms that are considered 'active' for this

<h2><a name="Conformance with DMTF Specifications">Conformance with
DMTF Specifications</a></h2>
<p>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:</p>
<ol>
<li><b>Provider Registration</b> - 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> <b>Indications </b>-Today Pegasus supports process
indications but does not
include any specific support for lifecycle indications.</li>
<li>
<p class="MsoNormal"><span style="color: black;"> </span><font style="color: rgb(0, 0, 0); font-weight: bold;">IncludeQualifiers
option on Instance Operations</font><span style="color: black;"><b> </b>
-
The DMTF specifications are unclear regarding the inclusion of
qualifiers on
CIM instances. 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). </span> 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.</p>
</li>
<li><b>LocalOnly option on instance
Operations </b>- With the 1.1 version of Specification for CIM
Operations over HTTP, the definition of the LocalOnly parameter for the
GetInstance and EnumerateInstances 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.</li>
<li>
<p class="MsoNormal"> <b>CIM MOF compiler function for
instance aliasing</b> - The Pegasus MOF compiler does not today support
this function. This function is planned for a future version.</p>
</li>
<li>
<p class="MsoNormal"><b> MultiRequest Oprations</b> - Pegasus
does not support the DMTF defined MultiRequest Operation option.</p>
</li>
<li>
<p class="MsoNormal"><b>MOFCompiler namespace pragma</b> - The
Pegasus compiler does not support the namespace pragma.</p>
</li>
</ol>
<h2><a name="Changes in This Release">Changes in This Release</a></h2>
<p>The development and release of each version of Pegasus is defined
and
controlled through Pegasus PEP documents. PEP 180 is the
controlling document for Pegasus 2.5.0 and PEP 239 is the controlling
document for this release. These PEPs list the original set of changes proposed and the
status of
each of those changes. Note that not all of the originally defined
functionality was completed for this release.</p>

</ol>
<p>For release 2.5.1, a number of additional changes were made( See PEP 239 for
more details):.</p>
<ol style="margin-top: 0in;" start="1" type="1">
<li>Significant performance improvements ( better than 10 to 1 for operations
and 3 to 1 for indications). (bug 4225)</li>
<li>Improved support for the several platforms (Solaris, MacOS, HardHat Linux)</li>
<li>Modified Makefile targets for easier usage.</li>
<li>Extended and reorganized unit and end-end tests.</li>
<li>Completed implementation of statistics gathering for operations.</li>
<li>Further integrated CMPI and added additional tests.</li>
<li>Consolidate some of the compile-time variables. Largely this meant moving
from separate variables for DISABLE and ENABLE to a single variable where the
value representes the state.</li>
<li>Corrected error where Pegasus could not maintain general whitespace in
strings (bug 4624).</li>
<li>SLP extended to allow optional use of OpenSLP as the Service Agent (SA) in place of
the Pegasus internal SA.</li>
<li>Changes to align OpenPegasus and Red Hat RPM packaging and configuration
options.</li>
<li>Additonal testing and integration of the JMPI provider manager.</li>
</ol>
<p>Specifically the status of several components of Pegasus functionality were
moved in status on the Feature Status Page as follows:</p>
<ol>
<li>Binary Repository move to green (production capable). (see bug 4388)</li>
<li>Out of Process providers</li>
<li>Pegasus Provider Interfaces, User Context for Linux and Unix</li>
