    Description

      +++ This bug was initially created as a clone of Bug #1491039 +++
      SELinux is denying tomcat from binding to port 9999 for JMX, with the following AVC denial in /var/log/audit.log:

      type=AVC msg=audit(1505248782.641:3017): avc:  denied  { name_bind } for  pid=10189 comm="java" src=9999 scontext=system_u:system_r:tomcat_t:s0 tcontext=system_u:object_r:jboss_management_port_t:s0 tclass=tcp_socket
      

      This worked without issue in previous versions of the targeted policy.

      Version-Release number of selected component (if applicable):

      • selinux-policy-targeted-3.13.1-166.el7.noarch
      • RHEL 7.4

      How reproducible:
      Always

      Steps to Reproduce:
      1. Create a new RHEL 7.4 machine
      2. yum install tomcat
      3. Add the following to /etc/sysconfig/tomcat
      JAVA_OPTS="-Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.rmi.port=9999 -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false "
      4. systemctl start tomcat.service

      Actual results:
      AVC denial

      Expected results:
      A successful bind, like previous versions of the policy.
