From ee1c7296ece67b5b35e528620c645a9c3f2a5c16 Mon Sep 17 00:00:00 2001 From: Aaron Conole Date: Mon, 19 Feb 2018 09:55:43 -0500 Subject: [PATCH] selinux: allow dpdkvhostuserclient sockets with newer libvirt Newer libvirt and openstack versions will now label the unix socket as an `svirt_tmpfs_t` object. This means that in order to support deploying with the recommended configuration (using a dpdkvhostuserclient socket), additional permissions need to be installed as part of the selinux policy.
