Description of problem: GlusterFS volumes of RDMA transport fails to fuse mount with following AVCs seen from audit logs: type=AVC msg=audit(1475736079.350:10478): avc: denied { ipc_lock } for pid=2686 comm="glusterfs" capability=14 scontext=unconfined_u:system_r:glusterd_t:s0 tcontext=unconfined_u:system_r:glusterd_t:s0 tclass=capability type=AVC msg=audit(1475736154.614:10485): avc: denied { ipc_lock } for pid=2309 comm="glusterd" capability=14 scontext=unconfined_u:system_r:glusterd_t:s0 tcontext=unconfined_u:system_r:glusterd_t:s0 tclass=capability Version-Release number of selected component (if applicable): Red Hat Gluster Storage Server 3.1 Update 3 Red Hat Enterprise Linux Server release 6.8 (Santiago) How reproducible: Always Steps to Reproduce: 1. Set up RDMA stack based on IPoIB. 2. Make sure that SELinux mode is set to 'Enforcing'. 3. Create a simple 1 brick volume with transport type RDMA 4. Start the volume 5. Try fuse mounting the volume Actual results: Mount failed. Please check the log file for more details. Expected results: Mount should be successful.
