SELinux Policy

[george1421]

No luck compiling for me on Centos 6.7

[root@centtest SELinux]# make -f /usr/share/selinux/devel/Makefile fog.pp
Compiling targeted fog module
/usr/bin/checkmodule:  loading policy configuration from tmp/fog.tmp

@george1421 Centos 6 appears to be missing some of the modules I require. I’ve been trying to hunt down the exact dependencies I’d need, or if need be, a new policy with different rules / modules.

That’s why we are going through this. No worries on my part. We’ll get them worked out.

This installed fine on Fedora 23.

the SELinux stuff works fine on Fedora 23 Server so far.

I’ve tried this setup on a virtualized Fedora 23 FOG server. I’ve imaged 2 computers so far with this setup. One of them, I tried out WOL just to confirm that still works - it does.

Holding off on adding this to the WiKi - It is my hopes that enough people will try this out that it can be added to Trunk by the @Developers and implimented in FOG 1.3.0.

@Jbob As far as I can tell, in Fedora 23 Server Minimal, The SELinux module breaks the FOG_FTP_IMAGE_SIZE feature.

There’s also this issue. I’m just going to tag the link and description here.

Another problem that needs addressed with the SELinux setup:

@Jbob I really want to see SELinux incorporated into fog. I know it’s finals time, and many a aspiring young adult is quite busy making a future for themselves. That’s fine. I just don’t want this swept under the rug.

I’ve noticed that no changes have been made to the SELinux stuff.

[root@fog-server trunk]# cd SELinux
[root@fog-server SELinux]# ls
fog.fc  fog.if  fog.pp  fog.te  tmp
[root@fog-server SELinux]# make -f /usr/share/selinux/devel/Makefile fog.pp
make: 'fog.pp' is up to date.

That’s fine - but if anyone wants me to run some tests, I’m up for it.

@Developers Apologies for spamming this thread to death… but I’d like to see a fully functional SELinux policy for FOG 1.3.0 for at least the CentOS 7 platform. Has any progress been made with the below problems by anyone?

[Wayne Workman]

I’m learning about these:

yum install setroubleshoot setroubleshoot-server -y

Apparently those two packages will help you analyze and tune a SELinux policy for anything.

Another amazing resource (just watched the whole thing):

I feel a lot better about Security Enhanced Linux now (SELinux), and I’ll definitely be creating my own modules for it. Luckily for me I’ve run a production fog server in Permissive mode for a HOT minute now, so all the information I would need to create a module is already there.

[Joe Schmitt]

@Wayne-Workman I’ll update the policy hopefully within the week.

Bumping this - it would be so nice to have SELinux enabled as a standard configuration.
