Description of problem:
When running API kickstart.snippet.listDefault, it produces AVC on server side and produces "xmlrpc.client.Fault: <Fault -1: 'redstone.xmlrpc.XmlRpcFault: unhandled internal exception: null'>" on client side.

Version-Release number of selected component (if applicable):
# rpm -qa | grep selinux
libselinux-python-2.5-12.el7.x86_64
libselinux-utils-2.5-12.el7.x86_64
libselinux-2.5-12.el7.x86_64
osa-dispatcher-selinux-5.11.98-1.el7.centos.noarch
selinux-policy-3.13.1-183.el7.noarch
spacewalk-selinux-2.8.2-1.el7.centos.noarch
selinux-policy-targeted-3.13.1-183.el7.noarch

# rpm -q spacewalk-java
spacewalk-java-2.8.49-1.el7.centos.noarch

How reproducible:
always

Steps to Reproduce:
1. call API kickstart.snippet.listDefault

Actual results:
It results in AVC and causes an exception.

Expected results:
No AVC and no exception. Tomcat? probably should have access to /var/lib/cobbler/snippets.

SELinux is preventing /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-5.b13.el7.x86_64/jre/bin/java from read access on the directory /var/lib/cobbler/snippets.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that java should be allowed read access on the snippets directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'java' --raw | audit2allow -M my-java
# semodule -i my-java.pp
