This is a weird one.

It seems I am unable to create and install policy modules, as I see the same error every time.

Code:
Error opening /etc/selinux/strict/contexts/files/file_contexts.local: No such file or directory


Which is absolutely correct. It does not exist. Why?

I thought I might try to re-install selinux-base-policy, but each time it fails with..
Code:
>>> Failed to emerge sec-policy/selinux-base-policy-2.20130424-r1, Log file:

 * ERROR: sec-policy/selinux-base-policy-2.20130424-r1 failed (compile phase):

 *

Why am I seeing.......?
Makefile:8: /usr/share/selinux/targeted/include/Makefile: No such file or directory
when my system is set to strict and not targeted?

Any ideas what the hell is going on with my SELinux box.
I create policies to hopefully clear the mess in the avc log, but the policies don't resolve the problems.

SELinux is not for thickos like myself.

I will never be able to run in enforce mode.

Damn. :evil:

** UPDATE **

It seems after a few....
Code:
rlpkg

and a few reboots portage is now able to download the security policies for switching to a targeted policy.

I've tried this way and it doesn't work for me. My SELinux config is 'strict', is this the problem?
Code:

sam ~ # sestatus
SELinux status:                 disabled
sam ~ # ls /etc/selinux/strict/contexts/files -l
total 368
-rw-r--r--. 1 root root  69196 Jul  9 10:47 file_contexts

-rw-r--r--. 1 root root   1909 Jul  9 10:47 file_contexts.homedirs
-rw-r--r--. 1 root root    229 Jul  9 10:15 file_contexts.subs_dist
-rw-r--r--. 1 root root    130 Jul  9 10:15 media

Please help me!

My SELinux type is permissive and strict, should I have to change it to target?

If you have it set to strict then that is fine.
It seems if you wish to switch to targeted then you may have a problem.

I was chatting with one of the developers / maintainers of SELinux for Gentoo last night.
He is intrigued by my problem and would like to help further.

If I switch to targeted portage fails, I have to switch back to strict to fix this.

My main issue now is, when I switch to targeted, I can't get SELinux to switch the policies.
It's kind of like the dependency hell you get with portage sometimes.

I will be chatting with Sven later today, to see if there is a resolution to this, otherwise I may have to file a bug.

Hey, you never know, it may be that I have done something terribly wrong. :lol:

This was resolved by touching the file. Big thanks to Swift for the tip.

Same issue here, solving by touch the /etc/selinux/${POLICY}/contexts/files/file_contexts.local file.

Update:

seems change policy type can result in this problem, see https://bugs.gentoo.org/show_bug.cgi?id=473502

re-emerging the sys-libs/libselinux-2.1.13-r4 solves the problem too.
