Description of problem: OpenvSwitch is an openflow switch, which may be configured to connect to openflow controller over a TCP connection. selinux blocks /usr/sbin/ovs-vswitchd to establish a TCP session to the controller. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. yum install openvswitch 2. systemctl start openvswitch 3. ovs-vsctl add-br br0 4. ovs-vsctl set-controller br0 tcp:127.0.0.1:6653 Actual results: selinux blocks tcp connection Expected results: allow tcp connection if some policy was provided. Additional info: The port number used in openflow is 6653 by IANA assignment, and 6633 is also commonly used.
Could you attach the AVC messages?
SELinux is preventing /usr/sbin/ovs-vswitchd from name_connect access on the tcp_socket . ***** Plugin connect_ports (99.5 confidence) suggests ********************* If you want to allow /usr/sbin/ovs-vswitchd to connect to network port 6653 Then you need to modify the port type. Do # semanage port -a -t dns_port_t -p tcp 6653 ***** Plugin catchall (1.49 confidence) suggests ************************** If you believe that ovs-vswitchd should be allowed name_connect access on the tcp_socket 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: # grep ovs-vswitchd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:openvswitch_t:s0 Target Context system_u:object_r:unreserved_port_t:s0 Target Objects [ tcp_socket ] Source ovs-vswitchd Source Path /usr/sbin/ovs-vswitchd Port 6653 Host localhost.localdomain Source RPM Packages openvswitch-2.0.0-1.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-106.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name localhost.localdomain Platform Linux localhost.localdomain 3.12.6-300.fc20.x86_64 #1 SMP Mon Dec 23 16:44:31 UTC 2013 x86_64 x86_64 Alert Count 1511 First Seen 2013-12-20 16:31:26 JST Last Seen 2014-01-10 11:12:33 JST Local ID 2cfe66ca-f72a-4dc0-ba1d-5402e90884f9 Raw Audit Messages type=AVC msg=audit(1389319953.771:533): avc: denied { name_connect } for pid=2674 comm="ovs-vswitchd" dest=6653 scontext=system_u:system_r:openvswitch_t:s0 tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket type=SYSCALL msg=audit(1389319953.771:533): arch=x86_64 syscall=connect success=no exit=EINPROGRESS a0=1f a1=7fff0de16350 a2=10 a3=0 items=0 ppid=2673 pid=2674 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=ovs-vswitchd exe=/usr/sbin/ovs-vswitchd subj=system_u:system_r:openvswitch_t:s0 key=(null) Hash: ovs-vswitchd,openvswitch_t,unreserved_port_t,tcp_socket,name_connect
