Fixed In Version: Doc Type: Bug Fix
Doc Text:
Previously, the SELinux policy prevented the GlusterFS volumes configured for the Remote Direct Memory Access (RDMA) transport from the File System in User Space (FUSE) mounting. 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 12:46:24 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;
  class capability { ipc_lock };
}

allow glusterd_t glusterd_t : capability { ipc_lock };

# 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 10) to tmp/glusterfs-rdma.mod
Creating targeted glusterfs-rdma.pp policy package
rm tmp/glusterfs-rdma.mod tmp/glusterfs-rdma.mod.fc
# semodule -i glusterfs-rdma.pp 
#

The Makefile comes from selinux-policy package.

Hi Milos,

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.
