Description of problem:
Need to make significant changes to SElinux policy in order to accommodate glance with solidfire cinder backend

Using newest openstack-selinux from brew:
[root@overcloud-controller-1 ~]# rpm -qa | grep openstack-sel
openstack-selinux-0.8.6-2.el7ost.noarch

Need to run this script to disable all blocking selinux policies:

[stack@director images]$ cat selinux.sh 
#!/bin/bash -x

ssh heat-admin.159.25 "sudo yum install setroubleshoot -y"

while `glance --os-image-api-version 1 image-create --container-format bare --disk-format qcow2 --store cinder --progress --file ubuntu-14.04-server-cloudimg-amd64-disk1.img --name test-sf 2>&1 | grep -iq '500 internal'`;do

ssh heat-admin.159.25 "sudo sealert -a /var/log/audit/audit.log 2>/dev/null" >> /tmp/selinux.log

ssh heat-admin.159.25 "sudo sealert -a /var/log/audit/audit.log 2>/dev/null | grep ausearch | sed 's/^#//' | xargs -I {} bash -c 'sudo {}' 2>/dev/null | grep semodule | xargs -I {} bash -c 'sudo {}'"

done



The following policies need to be installed: see attachment

Also, I get this to work once with the script, but then it fails again when it tries to access different block devices:


SELinux is preventing /usr/bin/python2.7 from write access on the blk_file sdg.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that python2.7 should be allowed write access on the sdg blk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'glance-api' --raw | audit2allow -M my-glanceapi
# semodule -i my-glanceapi.pp
