Fixed In Version: selinux-policy-3.13.1-105.el7
Doc Type: Bug Fix
Doc Text:
Previously, the SELinux policy prevented the GlusterFS volumes configurated for the Remote Direct Memory Access (RDMA) transport from starting. With this update, a patch has been applied that fixes this bug, and the SELinux denial no longer occurs in the described situation.

Comment 1 Milos Malik 2016-10-13 12:43:41 UTC
Here is a workaround until an official fix becomes available:

# cat glusterfs-rdma.te 
policy_module(glusterfs-rdma, 1.0)

require {
  type glusterd_t;
  type infiniband_device_t;
  class capability { ipc_lock };
  class chr_file { getattr open read write };
}

allow glusterd_t glusterd_t : capability { ipc_lock };
allow glusterd_t infiniband_device_t : chr_file { getattr open read write };

# make -f /usr/share/selinux/devel/Makefile 
Compiling targeted glusterfs-rdma module
/usr/bin/checkmodule:  loading policy configuration from tmp/glusterfs-rdma.tmp
/usr/bin/checkmodule:  policy configuration loaded
/usr/bin/checkmodule:  writing binary representation (version 17) to tmp/glusterfs-rdma.mod
Creating targeted glusterfs-rdma.pp policy package
rm tmp/glusterfs-rdma.mod.fc tmp/glusterfs-rdma.mod
# semodule -i glusterfs-rdma.pp 
#

The Makefile comes from selinux-policy-devel package.

Hi Miroslav,

With the local policy provided in Comment #1, I could create, start and fuse mount RDMA transport type GlusterFS volumes and AVCs from bug description are no longer seen.
