Controller code verification

All controller code is signed by Hewlett Packard Enterprise. Validating the certificate via jarsigner should return an Hewlett Packard Enterprise X.509 certificate similar to the following:

X.509, CN=Hewlett-Packard, OU=HPGlobal, OU=Digital ID Class 3 - Java Object Signing, O=Hewlett-Packard, L=Andover, ST=Massachusetts, C=US

[certificate is valid from 11/14/12 4:00 PM to 11/15/14 3:59 PM]

X.509, CN=VeriSign Class 3 Code Signing 2010 CA, OU=Terms of use at https://www.verisign.com/rpa (c)10, OU=VeriSign Trust Network, O="VeriSign, Inc.", C=US

[certificate is valid from 2/7/10 4:00 PM to 2/7/20 3:59 PM]

[CertPath not validated: null]

If a controller jar or war file is tampered with, the jar verification fails, and the container does not start up.

If an application is not signed by Hewlett Packard Enterprise, or has its certificate trusted by the controller (see section below), the application is not allowed to run on the controller.

Adding certificates to the jar-signing truststore

To deploy other signed applications onto the controller, use the Java keytool to import the public certificate that was used to sign the application jars and/or zips into the controller jar-signing truststore (/opt/sdn/admin/sdnjar_trust.jks):

/opt/sdn/openjdk8-jre/bin/keytool -importcert -keystore /opt/sdn/admin/sdnjar_trust.jks -file signed_app.cer -alias mysignedcert

The controller needs to be restarted for the new truststore to take effect.

Running the SDN Controller Without Jar-Signing Validation

The SDN Controller enforces jar/zip-signing validation by default. For an experimental/development environment where unsigned applications need to be deployed, jar/zip-signing validation can be turned off altogether:

Use the following command to stop the SDN Controller:

sudo service sdnc stop

Modify the /opt/sdn/virgo/bin/dmk.sh script to add the following option to the list of JMX_OPTS:

-Dsdn.signedJar=none

For example:

cd $KERNEL_HOME; exec $JAVA_EXECUTABLE \
$JAVA_OPTS \
$DEBUG_OPTS \
$JMX_OPTS \
-XX:+HeapDumpOnOutOfMemoryError \
-XX:ErrorFile=$KERNEL_HOME/serviceability/error.log \ 
-XX:HeapDumpPath=$KERNEL_HOME/serviceability/heap_dump.hprof \
-Dsdn.signedJar=none \
-Djava.security.auth.login.config=$AUTH_LOGIN \
-Dorg.eclipse.virgo.kernel.authentication.file=$AUTH_FILE \

Start the SDN Controller:

sudo service sdnc start

To enable jar/zip-signing validation, remove the line containing the -Dsdn.signedJar=none option from the /opt/sdn/virgo/bin/dmk.sh script and restart the controller.
