When starting the X server from the console (using the startx script
that is being shipped with package xinit from X.Org), a few more
permissions are needed from the reference policy.
The label is for a file created by the startx script (from X.Org) and
the module being requested is ipv6 (which can be disabled by other
means).
Allow xserver_restricted_role domains to call/start Xorg (using startx), fixes
15-second lag/timeout (needs siginh permission as provided by
xserver_domtrans).
Apparently, the 15-second lag (or some other behavior) was already detected
in the past, giving rise to the SIGINH permission in the xserver_domtrans()
interface.
However, domains that are given the xserver_(restricted_)role do not call
the xserver_domtrans but rather the "standard" domtrans_pattern.
The new patch suggests to use xserver_domtrans in the
xserver_restricted_role, which automatically includes the siginh permission
then.

This patch adds a new interface to the cpufreqselector module
to allow dbus chat. It then uses such interface to allow dbus chat
with system_dbusd_t and xdm_t. This patch also adds some other
permissions needed to run cpufreqselector.
As one of entrypoint application, crond_t should have had the
files_polyinstantiate_all() interface called so that pam_namespace.so
could work well in crond_t. Otherwise the crond_t lacks the sys_admin
permission to make use of pam_namespace.so
BTW, the allow_polyinstantiation boolean need to be toggled true
accordingly.

Entry point applications such as crond or atd use pam_loginuid.so for
the session phase of their PAM config files to set the process loginuid
attribute. Accordingly logging_set_loginuid interface should have been
called, otherwise we could run into below error message:

BTW, other entrypoint applications such as sshd/login/remote have had
this interface called for their domains.

On my system, I use XFCE and start X from the commandline (using "startx")
rather than through a graphical DM. During the start-up, XFCE4 creates
temporary ICE files in /tmp (like /tmp/.xfsm-ICE-ABCDEF) which are later
read in by iceauth and at some point X.
I'm not that good at the entire ICE stuff, but without this, I was unable to
shut down my session ("log off").

I realized the policy wasn't complete for handling udev_tbl_t dirs, and
updating it wouldn't work because we couldn't make a filetrans on dirs,
since all the dirs in /dev would become udev_tbl_t. i.e. this would have
been required, but would make problems: dev_filetrans(udev_t, udev_tbl_t, dir);

Various changes to the Xen userspace policy, including:
- Add gntdev and gntalloc device node labeling.
- Create separate domains for blktap and qemu-dm rather than leaving them in xend_t.
- No need to allow xen userspace to create its own device nodes anymore;
this is handled automatically by the kernel/udev.
- No need to allow xen userspace access to generic raw storage; even if
using dedicated partitions/LVs for disk images, you can just label them
with xen_image_t.
The blktap and qemu-dm domains are stubs and will likely need to be
further expanded, but they should definitely not be left in xend_t. Not
sure if I should try to use qemu_domain_template() instead for qemu-dm,
but I don't see any current users of that template (qemu_t uses
virt_domain_template instead), and qemu-dm has specific interactions
with Xen.

Since sudo 1.7.4, the timestamp directory has moved from /var/run/sudo to
/var/db/sudo, lib or adm (in that order). See also the sudo changeset
http://www.sudo.ws/repos/sudo/rev/8c9440423d98
Keeping the "old" one (/var/run/sudo) for a while for those systems where
sudo has not been updated yet (change is since 1.7.4, Jul 14 2010).

On an Xorg 1.9 system with evdev driver (for keyboard InputClass), the
xserver_t domain needs to be able to read from the proper device nodes as
well as query the udev_tbl_t directory and udev itself.
