Description Maros Zatko 2014-01-10 14:08:22 UTC
Description of problem:
Livecd-creator silently disables selinux, although it's subsequently re-enabled upon finish, the machine stays unprotected for a considerable amount of time

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

How reproducible:

Steps to Reproduce:
1. vim $(which livecd-creator)
2. enter :151 (i.e. navigate to line 151)
3. observe selinux being disabled

Actual results:
The machine is exposed during ISO creation due to disabled selinux.

Expected results:
Protected machine while building ISO images.

Additional info:
There is a possibility that machine will stay exposed because of livecd-creator or python/library crash.

Comment 1 Brian Lane 2014-01-10 15:16:34 UTC
livecd-creator cannot run in enforcing mode.

Comment 2 Daniel Walsh 2014-01-10 16:32:33 UTC
Why not?

Comment 3 Brian Lane 2014-01-10 18:09:51 UTC
I don't remember exactly why, other than it not working.

Should it be able to? I've never had success with any of our image building tools and selinux. We also have other tools that don't work with enforcing turned on -- lorax, anconda image installs, and livemedia-creator when running anaconda on an image or directory install. IIRC the builders are running in permissive mode.

Comment 4 Daniel Walsh 2014-01-10 18:28:46 UTC
I know we have had livecd-tool working with SELinux in enforcing mode in the past.

/usr/bin/livecd-creator	--	system_u:object_r:livecd_exec_t:s0

I think the other tools if labeled livecd_exec_t should work also.

This is basically an unconfined domain that is allowed to put labels on disk that the kernel does not understand.

If you try the other tools with SELinux in enforcing mode, and labeled livecd_exec_t, it should work.  If you get AVC's I would like to look at them.

Comment 5 Brian Lane 2014-01-14 19:07:47 UTC
Looks like things have improved and the switch is no longer needed. I successfully built a couple test images with the host in enforcing for the whole build so I'll revert that patch.
