On systems such as Arch Linux, all programs which are usually located in
/bin, /sbin, /usr/bin and /usr/sbin are present in /usr/bin and the
other locations are symbolic links to this directory. With such a
configuration, the file contexts which define types for files in
/bin, /sbin and /usr/sbin need to be duplicated to provide definitions
for /usr/bin/...
As the "/bin vs. /usr/bin" part of the needed definitions has already
been done with the "usr merge" patches, the next step consists in
duplicating file contexts for /usr/sbin. This is what this patch does
for all modules which are not in contrib.
This is the second iteration of an idea I have previously posted on
http://oss.tresys.com/pipermail/refpolicy/2017-March/009176.html
Some applications might want to execute gpg without requiring a
transition. A possible use case is to allow applications to validate
signatures (made by GnuPG). As long as the application doesn't need to
generate signatures itself and its trustdb is not marked as
gpg_secret_t, it suffices to grant it gpg_exec().
Note that it does require the application to have read/write rights in
the directory where the trustdb is stored (as gpg tries to generate lock
files where the trustdb file is located).

When mozilla_role interface is called, 1st argument is the caller's
role and 2nd argument is the caller's domain, such as:
mozilla_role(staff_r, staff_t)
When mozilla_role calls mozilla_run_plugin, the passed 2nd argument
should be the caller's role rather than its domain, so $1 not $2 should
be used.

Not anymore apparently. Been running now for quite some time without these
privileges and I get no problems with it. Retry:
Mozilla/Firefox creates temporary files for its plugin support (for instance
while viewing flc streams), like /tmp/plugtmp/plugin-crossdomain.xml.
Update policy to allow it to create its own tmp type and perform a file
transition when creating a file or directory in a tmp_t location (like
/tmp).

Allow mplayer to behave as a plugin for higher-level (interactive)
applications, such as browser plugins

In order to work with webcams, mplayer domain needs write access to the
v4l_device_t (updates and reconfiguration of the video device)

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.
The login or ssh program will relabel a tty or pty device after users
log in, and the vlock domain would only need to use the relabeled tty
or pty device, rather than the whole ttynode or ptynode attribute.

Both the system administrator and the unprivileged user could use vlock
to lock the current console when logging in either from the serial console
or by ssh.

Retry: forgot to include attribute mmap_low_domain_type attribute to domain_mmap_low() :
Inspired by similar implementation in Fedora.
Wine and vbetool do not always actually need the ability to mmap a low area of the address space.
In some cases this can be silently denied.
Therefore introduce an interface that facilitates "mmap low" conditionally, and the corresponding boolean.
Also implement booleans for wine and vbetool that enables the ability to not audit attempts by wine and vbetool to mmap a low area of the address space.
Rename domain_mmap_low interface to domain_mmap_low_uncond.
Change call to domain_mmap_low to domain_mmap_low_uncond for xserver_t. Also move this call to distro redhat ifndef block because Redhat does not need this ability.
