RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: selinux-policy-3.7.19-205.el6
Doc Type: Bug Fix
Doc Text:
Previously, SELinux returned AVC denial messages during attempts to attach an LVM volume to a Red Hat OpenStack 3 instance. The relevant SELinux policy rules have been modified to add an additional MCS attribute for hald_t SELinux domain, and AVC denial messages are no longer returned when attaching LVM volume to a Red Hat OpenStack 3 instance.

Description Eric Harney 2013-06-06 21:24:21 UTC 
+++ This bug was initially created as a clone of Bug #965311 +++

Description of problem:
SSIA

[root@localhost ~]# grep AVC /var/log/audit/audit.log 
type=AVC msg=audit(1369085100.398:307633): avc:  denied  { read } for  pid=9144 comm="hald-probe-stor" path="/dev/sda" dev=devtmpfs ino=147635 scontext=system_u:system_r:hald_t:s0 tcontext=system_u:object_r:svirt_image_t:s0:c388,c537 tclass=blk_file

Version-Release number of selected component (if applicable): 
openstack-selinux-0.1.2-10.el6ost.noarch

How reproducible: Unknown; was not able to reproduce

Steps to Reproduce:
1. Fresh install
2. Create instance
3. Create volume
4. Attach instance to volume

Actual results: AVC denial

I will have to reproduce this and have specific steps.

--- Additional comment from Kashyap Chamarthy on 2013-06-06 16:06:58 EDT ---

Possible test reproducer for attaching a volume to an instance:

------------------------------------------------
	# Create a cinder volume, and list it
	$ cinder create --display_name=bootable_volume 1
	$ cinder list

	# Add the cinder volume to env. This is the output of "cinder list"
	$ VOLUME_ID=2c370395-7f59-4c89-b312-ba35dbb986c0
	$ echo $VOLUME_ID

	# boot an instance
	$ nova boot --image e1b71961-d66d-4315-8e83-32aa1bd44f3f --flavor 1 --key_name oskey
f17-builder

	# Ensure the above booted instance is ACTIVE
	$ nova list | grep f17-builder
	$ cinder list
	
	# Attach a volume
	$ nova volume-attach f17-builder 2c370395-7f59-4c89-b312-ba35dbb986c0 /dev/vdb
	$ cinder list
	$ ssh -i oskey.priv 192.168.32.4
------------------------------------------------

I reproduced this (the logged AVCs) by following the same steps as above: install, boot vm, attach an LVM iSCSI Cinder volume.

But, it doesn't seem to break anything, and the attach works.

Unclear what is accessing /dev/sda, maybe something triggered by iscsiadm.

Same openstack-selinux ver, openstack-nova-* 2013.1.1-3.

--- Additional comment from Eric Harney on 2013-06-06 16:17:21 EDT ---

Note: /dev/sda is the device node for the disk created when the iSCSI initiator logs in during volume attach.

This would be a general bug in policy and would happen with or without openstack, it should be fixed.

Could we get qa_ack+?
Comment 4 Miroslav Grepl 2013-06-12 10:53:03 UTC 
Actually we need to add a mcs attribute.
Comment 5 Miroslav Grepl 2013-06-12 10:54:30 UTC 
Fixed in selinux-policy-3.7.19-205.el6
