Deprecate mmap_file_perms and mmap_files_pattern since they are not fully
informative about their access. Replace with a full set of permission
set macros for mmap.
Requested for selinux-testsuite usage.
Setup attribute user_runtime_content_type in userdomain for files in /run/user/%{USERID}/* interfaces to associate this attribute with types and interfaces to delete types with this attribute.

This is probably RHEL only - seeing directories in /run/user/$(UID) created as
tmpfs_t rather than user_runtime_t. This appears fixed in newer systemd-logind.
It appears to have been fixed in systemd git repo by Nicolas Iooss 02-Feb-2016

I don't see this merged into RHEL 7.x as of now but as some point it hopefully
will be merged in and this can go away.

Label some shell scripts from bridge-utils correctly. Maybe have ifdef
distro_debian around this, not sure what upstream is doing.
systemd_nspawn_t needs to manage the /etc/localtime symlink if you have a
labeled chroot.
Another dontaudit for mon_local_test_t to stop it spamming the logs.
Support a .d directory for dnsmasq config files.
Remove complement (~) and wildcard (*) in allow rules so that there are no
unintentional additions when new permissions are declared.
This patch does not add or remove permissions from any rules.
Not auditing this turns out to be the wrong choice for
several reasons.
For normal application functioning the user domain
should be able to create netlink_kobject_uvent_socket
sockets.

This patch is slightly more involved than just running sed. It also adds
typealias rules and doesn't change the FC entries.
The /dev/apm_bios device doesn't exist on modern systems. I have left that
policy in for the moment on the principle of making one change per patch. But
I might send another patch to remove that as it won't exist with modern
kernels.
Added mono_run for unconfined and also xserver_role and allow it to dbus
chat with xdm.
Allow sysadm_t to read kmsg.
Allow user domains to dbus chat with kerneloops for the kerneloops desktop
gui. Also allow them to chat with devicekit disk and power daemons.
Allow gconfd_t to read /var/lib/gconf/defaults and /proc/filesystems
I believe that I have addressed all the issues Chris raised, so here's a newer
version of the patch which applies to today's git version.

Since the window managers are not limited by gnome-shell, the
userdomain module is modified by this patch in order to use
separate optional conditionals for the gnome and wm role templates.

- add systemd service macro sets
- add some documentation
- add some recursion to some macro sets (ipv perm, object class sets)
- deprecate domain_trans and domain_auto_trans
- remove unpriv_socket_class_set
Let unprivileged users list filesystems mounted on mount points such
as /mnt (cdrom, FAT, NTFS and so on).
This makes a great difference to the usability and effectiveness of
graphical filesystem browsers such as Gnome Nautilus and currently
comes at no security penalty because mounted filesystems can be
listed with programs such as the "df" program from GNU coreutils or
by simply reading /proc/mounts.

Let unprivileged and administrative users read symbolic links on
filesystems that do not support extended attributes (xattr) such
as cdroms, FAT, NTFS and so on.

Introduce a new file context for user certificates (user_cert_t)
located in home directories.
Introduce new auxiliary interfaces to read and manage such files
files and directories.
Thanks to Christopher PeBenito for the useful suggestions that
led to this improved version of the patch.
Compared to the previous version, this patch adds the ability to
search the user home directories in the new interfaces.

Improve the existing user domain template policy:
- better support for the "user_rw_noexattrfile" boolean (enable
write operations on filesystems that do not support extended
attributes, such as FAT or cdrom filesystem);
- add support for a new "user_exec_noexattrfile" boolean to
control the execution of files from filesystems that do not
support extended attributes (potentially dangerous);
- add support for a new "user_write_removable" boolean which
enables write operations on removable devices (such as
external removable USB memory, USB mobile phones, etc).
Note that devices might be removable but support extended
attributes (Linux xattr filesystems on external USB mass storage
devices), so two separate booleans are needed for optimal
configuration flexibility.
Writing to removable mass storage devices is a major cause of
leakage of confidential information, so the new boolean defaults
to false.
Disable raw access for MLS policies (thanks to Christoper
PeBenito for suggesting this).
This new version of the patch correctly includes the definitions
of the new booleans (by including the .te file differences).

The Portable Hardware Locality (hwloc) software package provides a
portable abstraction (across OS, versions, architectures, ...) of the
hierarchical topology of modern architectures, including NUMA memory
nodes, sockets, shared caches, cores and simultaneous multithreading. It
also gathers various system attributes such as cache and memory
information as well as the locality of I/O devices such as network
interfaces, InfiniBand HCAs or GPUs.
Following changes enable:
- add interface to change dirs in /var/run
- add optional policies for hwloc-dump-hwdata
V3:
Remove files_rw_pid_dirs()
Call hwloc_admin(sysadm_t) instead of hwloc_manage_runtime(sysadm_t)
Adjust calls to renamed hwloc dhwd run and exec interfaces

-This patch is needed since CIL does not allow duplicate
role declarations. The roles for system_r, staff_r, sysadm_r, and
user_r were already declared in kernel.te. Since the roles are
pulled in from require statements in the appropriate interfaces,
the duplicate role declarations could be deleted in modules for
auditadm, staff, sysadm, and userdomain.
-Move a role declaration that used an argument passed into the
userdom_base_user_template into a gen_require statement.
Since commit 2d0c9cec mls_file_read_up and mls_file_write_down
interfaces are deprecated even though they are still present.
Replace mls_file_read_up with mls_file_read_all_levels and
mls_file_write_down with mls_file_write_all_levels.
Unprivileged users don't need to read kallsyms and /boot/System.map.
This allow rule was introduced in the initial revision of userdomain.if in
2005, with commit b16c6b8c32a631a2e66265f6f60b664222760972:
