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 David Haines 2016-11-16 16:07:47 UTC 
+++ This bug was initially created as a clone of Bug #1381112 +++

Description of problem:
'yum provides /etc/selinux/targeted/contexts/files/file_contexts.local' erroneously indicates that selinux-policy-targeted-3.13.1-102.el7_3.4.noarch contains the file_contexts.local referred to.

The following shows how this was stumbled upon:
# audit2allow -a
[Errno 2] No such file or directory: '/etc/selinux/targeted/contexts/files/file_contexts.local'


Version-Release number of selected component (if applicable):

3.13.1-102.el7_3.4

How reproducible:
- Install selinux-policy-targeted-3.13.1-102.el7_3.4.noarch
- Run audit2allow -a
Comment 2 Simon Sekidde 2016-11-17 13:44:20 UTC 
David, 

I am unable to reproduce this error

[root@localhost ~]# lsb_release -d; getenforce; rpm -q selinux-policy-targeted; rpm -q policycoreutils-python; audit2allow -a
Description:	Red Hat Enterprise Linux Server release 7.3 (Maipo)

Comment 8 Simon Sekidde 2016-12-08 21:39:11 UTC 
David, 

Are you still seeing this problem with the latest selinux-policy packages?
Comment 9 Steven Haigh 2016-12-15 13:16:03 UTC 
I just did a clean new install of 7.3 from the DVD ISO media - then a yum -y update.

Packaged installed is:
selinux-policy-targeted-3.13.1-102.el7_3.7.noarch

I see:
# audit2allow -a /var/log/audit/audit.log 
[Errno 2] No such file or directory: '/etc/selinux/targeted/contexts/files/file_contexts.local'

A reinstall via 'yum reinstall selinux-policy-targeted' didn't fix the issue.

Fixed via:
# touch /etc/selinux/targeted/contexts/files/file_contexts.local

audit2allow now works as expected - however this should probably be fixed in the package installation.
Comment 10 Matthias Saou 2016-12-22 11:34:50 UTC 
I can confirm the same issue, affecting only clean installs of RHEL 7.3 (not systems updated from prior releases).

The problem, as described, is that the /etc/selinux/targeted/contexts/files/file_contexts.local file does not exist anymore on a new system, and the audit2allow command fails because of that. "touch"ing the file does indeed fix it.

This is with :
selinux-policy-3.13.1-102.el7_3.7.noarch
selinux-policy-targeted-3.13.1-102.el7_3.7.noarch

I have dug a bit into the rpm changes, comparing 3.13.1-60.el7 (RHEL 7.2) with selinux-policy-3.13.1-102.el7_3.7 (RHEL 7.3), and the problem is that this file used to be included empty, but is now referenced as %ghost and no longer included. This change broke audit2allow, since apparently it needs the file and doesn't automatically create it if missing.

selinux-policy-3.13.1-60.el7 spec :

[...]
%ghost %{_sysconfdir}/selinux/%1/contexts/files/*.bin \
%config(noreplace) %{_sysconfdir}/selinux/%1/contexts/files/file_contexts.local \
[...]

selinux-policy-3.13.1-102.el7_3.7 spec :

[...]
%ghost %{_sysconfdir}/selinux/%1/contexts/files/*.local \
%ghost %{_sysconfdir}/selinux/%1/contexts/files/*.local.bin \
[...]

The file needs to be set back to %config(noreplace), or audit2allow modified to create the file when it's missing.

Comment 20 billtang 2017-04-19 21:29:15 UTC 
I am experiencing the same issue with redhat 7.3 (kernel-3.10.0-514.16.1.el7.x86_64):

policycoreutils-python-2.5-11.el7_3.x86_64
policycoreutils-2.5-11.el7_3.x86_64
selinux-policy-targeted-3.13.1-102.el7_3.16.noarch
selinux-policy-3.13.1-102.el7_3.16.noarch

Is there a work around?

[root@host-1 ~]# audit2allow -a
[Errno 2] No such file or directory: '/etc/selinux/targeted/contexts/files/file_contexts.local'

[Errno 2] No such file or directory: '/etc/selinux/targeted/contexts/files/file_contexts.local'



workaround appears to be creating a zero length file
[root@host-1 ~]# touch /etc/selinux/targeted/contexts/files/file_contexts.local
Comment 22 Strahil Nikolov 2017-05-11 13:50:59 UTC 
Hello,

I can confirm that a fresh install of RHEL 7.3 is missing the file.
Also the "sepolicy manpage" command fails until a zero lenght file is created.
Comment 23 Tom Seewald 2017-05-13 04:02:10 UTC 
I can confirm the workaround in comment 21 has resolved the problem on my machines.
