Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Description of problem:
vdsm (system_u:system_r:virtd_t:s0-s0:c0.c1023) creates files under /etc/sysconfig/network-scripts via sudo, to configure host networking. They are created system_u:object_r:net_conf_t:s0 instead of system_u:object_r:bin_t:s0.

vdsm also calls /sbin/ifup via sudo.

This leads to errors like

avc:  denied  { getattr } for  pid=3273 comm="dhclient-script" path="/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt" dev=dm-0 ino=1044497 scontext=unconfined_u:system_r:dhcpc_t:s0 tcontext=unconfined_u:object_r:virt_var_lib_t:s0 tclass=file

I suspect this would lead to failures to acquire ip address via dhclient.

Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-155.el6_3.noarch

How reproducible:
100%

Steps to Reproduce:
1. edit host networking via vdsm
  
Actual results:
# ls -lZ /etc/sysconfig/network-scripts/ifcfg-eth0 
-rw-rw-r--. vdsm root unconfined_u:object_r:virt_var_lib_t:s0 /etc/sysconfig/network-scripts/ifcfg-eth0


Expected results:
-rw-r--r--. root root system_u:object_r:net_conf_t:s0  /etc/sysconfig/network-scripts/ifcfg-lo

How does this script create the files?  It looks like it creates them in /var/lib/libvirt and then mv's them into place.  It is probably best if the tool would just execute restorecon after it moves the files into place.

restorecon /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-lo /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt

Ok, we'll take it to vdsm. Thanks.

Patch of comment #2 has been abandoned due to a complete overhaul of relevant function. The following patch is what I suggest instead:

Verified on vdsm-4.9.6-32.0.el6_3.x86_64

-rw-rw-r--. root root system_u:object_r:net_conf_t:s0  ifcfg-eth0
