A quick guess: Maybe something like this in openvswitch.te: interface(`ovsvsctl_domtrans',` gen_require(` type openvswitch_t, openvswitch_exec_t; ') corecmd_search_bin($1) domtrans_pattern($1, openvswitch_exec_t, openvswitch_t) ') And in quantum.te: optional_policy(` ovsvsctl_domtrans(quantum_t) ') ? Whoops first part would be in openvswitch.if Added. commit fe27028c37e0eee41db98a82977ea5c86d7687cb Author: Miroslav Grepl <mgrepl> Date: Mon Apr 15 08:00:34 2013 +0200 Allow quantum to transition to openvswitch_t selinux-policy-3.11.1-90.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/selinux-policy-3.11.1-90.fc18 Package selinux-policy-3.11.1-90.fc18: * should fix your issue, * was pushed to the Fedora 18 testing repository, * should be available at your local mirror within two days.

Created attachment 734977 [details] Partial audit.log containing relevant AVCs. On Fedora 18 with selinux set to enforcing, ovs-vsctl is getting AVC denials: $ rpm -q selinux-policy selinux-policy-3.11.1-86.fc18.noarch $ getenforce Enforcing With the quantum-openvswitch-agent enable, ovs-vsctl is being called repeatedly, each time generating the following AVC: type=AVC msg=audit(1365797926.454:102983): avc: denied { execute } for pid=22881 comm="python" name="ovs-vsctl" dev="vda3" ino=163045 scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:object_r:openvswitch_exec_t:s0 tclass=file If I set selinux to permissive, I get a few other AVCs: $ setenforce 0 $ getenforce Permissive type=AVC msg=audit(1365797928.458:102996): avc: denied { execute } for pid=22908 comm="python" name="ovs-vsctl" dev="vda3" ino=163045 scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:object_r:openvswitch_exec_t:s0 tclass=file type=AVC msg=audit(1365797928.476:102997): avc: denied { read open } for pid=22910 comm="python" path="/usr/bin/ovs-vsctl" dev="vda3" ino=163045 scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:object_r:openvswitch_exec_t:s0 tclass=file type=AVC msg=audit(1365797928.476:102997): avc: denied { execute_no_trans } for pid=22910 comm="python" path="/usr/bin/ovs-vsctl" dev="vda3" ino=163045 scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:object_r:openvswitch_exec_t:s0 tclass=file type=AVC msg=audit(1365797928.486:102998): avc: denied { search } for pid=22910 comm="ovs-vsctl" name="openvswitch" dev="tmpfs" ino=109622 scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:object_r:openvswitch_var_run_t:s0 tclass=dir type=AVC msg=audit(1365797928.486:102998): avc: denied { write } for pid=22910 comm="ovs-vsctl" name="db.sock" dev="tmpfs" ino=109630 scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:object_r:openvswitch_var_run_t:s0 tclass=sock_file type=AVC msg=audit(1365797928.486:102998): avc: denied { connectto } for pid=22910 comm="ovs-vsctl" path="/run/openvswitch/db.sock" scontext=system_u:system_r:quantum_t:s0 tcontext=system_u:system_r:openvswitch_t:s0 tclass=unix_stream_socket And the original 'execute' AVC stops.
