libsepol/cil: Create functions to write the CIL AST The function cil_print_tree() has existed in cil_tree.c since the beginning of the development of CIL and secilc. Unfortunately, it used cil_log() at log level CIL_INFO to print out the AST and has suffered greatly from bit rot. Move the functions to write the CIL AST to cil_write_ast.c, update the functions, and write the AST to the FILE pointer passed in as an argument. The function cil_write_ast() supports writing the CIL AST at three different phases of the compiling a CIL policy. After parsing has been done and the parse tree has been created, after the CIL AST has been built, and after the CIL AST has been resolved. Signed-off-by: James Carter <jwcart2@gmail.com>

SELinux libraries and tools are packaged in several Linux distributions:
Build dependencies on Fedora:
# For C libraries and programs dnf install \ audit-libs-devel \ bison \ bzip2-devel \ CUnit-devel \ diffutils \ flex \ gcc \ gettext \ glib2-devel \ make \ libcap-devel \ libcap-ng-devel \ pam-devel \ pcre-devel \ xmlto # For Python and Ruby bindings dnf install \ python3-devel \ ruby-devel \ swig
Build dependencies on Debian:
# For C libraries and programs apt-get install --no-install-recommends --no-install-suggests \ bison \ flex \ gawk \ gcc \ gettext \ make \ libaudit-dev \ libbz2-dev \ libcap-dev \ libcap-ng-dev \ libcunit1-dev \ libglib2.0-dev \ libpcre3-dev \ pkgconf \ python3 \ python3-distutils \ systemd \ xmlto # For Python and Ruby bindings apt-get install --no-install-recommends --no-install-suggests \ python3-dev \ ruby-dev \ swig
To build and install everything under a private directory, run:
make clean distclean make DESTDIR=~/obj install install-rubywrap install-pywrap
On Debian PYTHON_SETUP_ARGS=--install-layout=deb needs to be set when installing the python wrappers in order to create the correct python directory structure.
To run tests with the built libraries and programs, several paths (relative to $DESTDIR) need to be added to variables $LD_LIBRARY_PATH, $PATH and $PYTHONPATH. This can be done using ./scripts/env_use_destdir:
DESTDIR=~/obj ./scripts/env_use_destdir make test
Some tests require the reference policy to be installed (for example in python/sepolgen). In order to run these ones, instructions similar to the ones in section install of ./.travis.yml can be executed.
To install as the default system libraries and binaries (overwriting any previously installed ones - dangerous!), on x86_64, run:
make LIBDIR=/usr/lib64 SHLIBDIR=/lib64 install install-pywrap relabel
or on x86 (32-bit), run:
make install install-pywrap relabel
This may render your system unusable if the upstream SELinux userspace lacks library functions or other dependencies relied upon by your distribution. If it breaks, you get to keep both pieces.
Setting CFLAGS during the make process will cause the omission of many defaults. While the project strives to provide a reasonable set of default flags, custom CFLAGS could break the build, or have other undesired changes on the build output. Thus, be very careful when setting CFLAGS. CFLAGS that are encouraged to be set when overriding are:
To install libsepol on macOS (mainly for policy analysis):
cd libsepol; make PREFIX=/usr/local install
This requires GNU coreutils:
brew install coreutils
