<h3>IPDK 23.07<a class="headerlink" href="#ipdk-23-07" title="Permalink to this heading"></a></h3>
<ul class="simple">
<li><p>This is the first release of K8s-Infra-Offload recipe that supports ES2K and DPDK targets.</p></li>
</ul>
</section>
<section id="highlights">
<h3>Highlights<a class="headerlink" href="#highlights" title="Permalink to this heading"></a></h3>
<section id="es2k-target">
<h4>ES2K target<a class="headerlink" href="#es2k-target" title="Permalink to this heading"></a></h4>
<ul class="simple">
<li><p>Support for Kubernetes Container Network Interface (CNI) to deploy pods and
enable pod-to-pod connectivity on a P4 target using hardware device interfaces.</p></li>
<li><p>Use of internal gateway with dummy MAC to enable layer-3 connectivity on the same node.</p></li>
<li><p>Support for dynamic Subfunctions on ES2K.
Subfunction is a lightweight function that has a parent PCI function on which it is
deployed. It is created and deployed in a unit of 1. Unlike SRIOV VFs, a subfunction
doesn’t require its own PCI virtual function. A subfunction communicates with the
hardware through the parent PCI function.</p></li>
<li><p>Infra Manager build support on ARM cores.</p></li>
</ul>

<section id="dpdk-target">
<h4>DPDK target<a class="headerlink" href="#dpdk-target" title="Permalink to this heading"></a></h4>
<ul class="simple">
<li><p>Support for internal gateway with dummy MAC to enable layer-3 connectivity on the
same node.</p></li>
<li><p>service of type=ClusterIP support.
Service Load Balancing within the node to allow multiple pods on same node to
act as end points providing any application service.</p></li>
<li><p>Bi-directional Auto Learning and Flow Pinning (a.k.a Connection Tracking),
used with load balancing, to allow consistent end point pod selection, once it
has been selected for the first packet.</p></li>
<li><p>DNS service provided by Core DNS pods to other pods.</p></li>

<li><p>Infra manager restarts on running anamoly test cases on fuzz testing using
defensics</p></li>
<li><p>Persistent /var/log/inframanager.log is not deleted after “make undeploy”</p></li>
<li><p>conf and few other params in “inframanager/config.yaml” are not used,

</section>
<section id="known-issues">
<h3>Known Issues<a class="headerlink" href="#known-issues" title="Permalink to this heading"></a></h3>
<ul class="simple">
<li><p>This release does not support multi-tenant or multi-node deployments. At
present, the underlying IPDK networking recipe needs to be run on bare metal
on host CPU cores. The entire node, used for deployment, is assumed to be a
trusted zone. However, gRPC/gNMI channels for communications are still
secured using TLS.</p></li>
<li><p>ES2K feature set is limited to pod-to-pod connectivity.</p></li>
<li><p>Incomplete integration for Network Policies.</p></li>
<li><p>Infra agent fails to come up if interface name is not correct</p></li>
<li><p>Less than expected number of PODs are in Running state</p></li>
<li><p>Infrap4d is not started by create_interfaces.sh script due to incorrect
BDF in es2k_skip_p4.conf</p></li>
<li><p>Inframanger crashes with error on sending invalid grpc messages from
Defensics for fuzz testing</p></li>
<li><p>Script create_interfaces.sh should report the status of the actions performed</p></li>
<li><p>Inframanager log level setting and some cleanup</p></li>
<li><p>Need support to set log level for all modules under Inframanager
from the config setting</p></li>
