Nightly LiveCD 20091009

LiveCD intermittently gets stuck during shutdown.  This might be happening after liveinst, or maybe without having run it.  Not sure.

Cc'ing dwalsh (SELinux) and rstrode (plymouth).  TTy1 shows several AVC messages when trying to shut down the live image.

See attachment#364763 [details]
Comment 2 James Laska 2009-10-14 11:10:47 EDT
Okay, Cc'ing dwalsh (SELinux) and rstrode (plymouth) for real this time.  See AVC messages on tty1 in the screenshot in attachment#364763 [details]
Comment 3 Daniel Walsh 2009-10-14 11:26:59 EDT
I can add the rules in Fixed in selinux-policy-3.6.32-26.fc12.noarch
But plymouthd_t is supposed to be a permissive domain. Access should have been allowed to the framebuffer and to request the kernel to load a module.

But I see success=no.  Which I think could be a bug in the kernel or the loading of the module failed for some other non SELinux error.
Comment 4 Daniel Walsh 2009-10-14 11:27:40 EDT
Should have said.

Fixed in selinux-policy-3.6.32-27.fc12.noarch
Comment 5 Eric Paris 2009-10-14 11:39:42 EDT
errno = -19 == -ENODEV.

I'm not certain that the -EPERM would be passed back up this path, but it might well not be an SELinux problem in this case...
Comment 6 Warren Togami 2009-10-14 16:07:00 EDT
Confirmed, -26 and -27 both allow LiveCD to shutdown after liveinst.

Bug #509632 in anaconda-12.38-1.fc12 (not yet in rawhide) fixed an issue where liveinst was screwing up stuff in /dev.  Could this possibly be related?
Comment 7 Bill Nottingham 2009-10-21 17:20:46 EDT
Given comment #4, should this be closed?
Comment 8 Jesse Keating 2009-10-21 18:09:39 EDT
Closing.
