Description Leszek Matok 2013-06-26 23:40:34 UTC

This is Fedora 19 beta + all updates, mostly from "fedora" repo (so I assume it's basically F19 proper by now).

The system has i5-3317U CPU with HD 4000 graphics.

Quake Live (http://www.quakelive.com/) loads but works with like 5 fps on this system, gfxinfo shows Gallium/llvmpipe rendering.

I couldn't figure out what's the problem, as games like Neverball and Xonotic worked ok, not to mention glxinfo and glxgears. So I've tried setenforce 0 and voila - everything works! So it must be SELinux-related.

Maybe it's because libGL loads /usr/lib64/dri/i965_dri.so to which Firefox probably isn't allowed access? I really don't know.

I don't know where to get correct info about SELinux denials for this. Can you tell me where to look?

Comment 1 Daniel Walsh 2013-06-27 14:44:53 UTC

ausearch -m avc -ts recent

Comment 2 Leszek Matok 2013-06-27 16:04:09 UTC

[root@ponton ~]# ausearch -m avc -ts recent
<no matches>

That explains no setroubleshoot whinge, I guess.

It's not a coincidence though, I can always fix this with setenforce 0 and break again by setting 1...

Comment 3 Daniel Walsh 2013-06-27 19:26:05 UTC

getsebool selinuxuser_direct_dri_enabled

Comment 4 Leszek Matok 2013-06-27 22:46:42 UTC

selinuxuser_direct_dri_enabled --> on

As I wrote in the original submission, everything OpenGL-related (including games like Xonotic) works. It's only Quake Live having a problem, presumably because it works from plugin-container, from Firefoxes context.

Comment 5 Miroslav Grepl 2013-06-28 08:42:53 UTC

# semodule -DB

re-test

# ausearch -m avc,user_avc -ts recent

# grep context /var/log/messages

Comment 6 Daniel Walsh 2013-06-28 11:02:16 UTC

Currently we dont allow mozilla_plugin_t to use the /dev/dri type devices.

If you install and compile this policy, I bet it will work better

# cat > myfirefox.te << _EOF
policy_module(myfirefox, 1.0)
gen_require(`
type mozilla_plugin_t;
')

dev_rw_dri(mozilla_plugin_t)
_EOF
# make -f /usr/share/selinux/devel/Makefile
# semodule -i myfirefox.pp

Comment 7 Leszek Matok 2013-06-28 16:40:14 UTC

↑ That set of commands worked (with \` ;)). I can play in Enforcing mode now.

I guess that answers Miroslav's needinfo as well...

Can this be made into permanent policy update?

Comment 8 Daniel Walsh 2013-06-28 18:19:33 UTC

186dc6c7a2f5a69107224e097a1c446ca369c6d7 and
186dc6c7a2f5a69107224e097a1c446ca369c6d7

Will cause the plugins to use the selinuxuser_direct_dri_enabled boolean, which should be on by default.
