Environment variable TMPDIR may be already set for the user building
and this could be equal to $XDG_RUNTIME_DIR or /tmp which are existing
directories. Then when running 'make clean', there are unintended side

Policy developers can set a default_range default to glblub and
computed contexts will be the intersection of the ranges of the
source and target contexts. This can be used by MLS userspace
object managers to find the range of clearances that two contexts
have in common. An example usage is computing a transition between
the network context and the context of a user logging into an MLS
application.
For example, one can add a default with
this cil:
(defaultrange db_table glblub)
or in te (base module only):
default_range db_table glblub;
and then test using the compute_create utility:
$ ./compute_create system_u:system_r:kernel_t:s0:c1,c2,c5-s0:c1.c20 system_u:system_r:kernel_t:s0:c0.c20-s0:c0.c36 db_table
system_u:object_r:kernel_t:s0:c1,c2,c5-s0:c1.c20
Some example range transitions are:
User Permitted Range | Network Device Label | Computed Label
---------------------|----------------------|----------------
s0-s1:c0.c12 | s0 | s0
s0-s1:c0.c12 | s0-s1:c0.c1023 | s0-s1:c0.c12
s0-s4:c0.c512 | s1-s1:c0.c1023 | s1-s1:c0.c512

Since Darwin systems do not have GNU sed installed, the Darwin sed is
missing the "regexp-extended" flag needed to modify the secilc markdown
files before processing with pandoc.
A quick fix for Mac users is to `brew install gnu-sed` and to use gsed.

"roleattribute" was referencing "typeattributeset", but I believe it should be referencing "roleattributeset" instead.

Converting to github markdown allows for easier integration with the
SELinux project wiki and viewing of documentation directly on github without
creating PDFs or reading through DocBook XML.
The conversion of DocBook to github markdown would not format tables or
keyword links properly. By maintaining the documentation in github
markdown in the repository, the content is well formatted with a table of
contents when viewing in the github wiki or in the repository.
The migration from DocBook to github markdown was done using Pandoc and
manual fixups. Mappings of CIL keywords to headings that were lost in the DocBook
conversion were added back. An introduction and design philosphy was
also pulled from the SELinux project wiki to provide more cohesion
to the current documentation.
Running make will now convert the github markdown into PDF and HTML.

Resolves https://github.com/SELinuxProject/cil/issues/3
An 'unordered' keyword provides the ability to append classes to the current
list of ordered classes. This allows users to not need knowledge of existing
classes when creating a class and fixes dependencies on classes when removing a
module. This enables userspace object managers with custom objects to be
modularized.
If a class is declared in both an unordered and ordered statement, then the
ordered statement will supercede the unordered declaration.
Example usage:
; Appends new_class to the existing list of classes
(class new_class ())
(classorder (unordered new_class))

This adds a userattribute statement that may be used in userroles and
constraints. The syntax is the same as typeattributset.
Also, disallow roleattributes where roles are accepted in contexts.
Specify a userattribute
(userattribute foo)
Add users to the set foo
(userattributeset foo (u1 u2))

Since the secilc compiler is independent of libsepol, move secilc out of
libsepol. Linke secilc dynamically rather than statically with libsepol.
- Move secilc source, test policies, docs, and secilc manpage to secilc
directory.
- Remove unneeded Makefile from libsepol/cil. To build secilc, run make
in the secilc directory.
- Add target to install the secilc binary to /usr/bin/.
- Create an Android makefile for secilc and move secilc out of libsepol
Android makefile.
- Add cil_set_mls to libsepol public API as it is needed by secilc.
- Remove policy.conf from testing since it is no longer used.
