Installing a cil module with invalid mlsconstrain syntax currently results in a segfault. In the following module, the right-hand side of the second operand of the OR is a list (mlstrustedobject): $ cat test.cil (class test (foo) ) (classorder (unordered test)) (mlsconstrain (test (foo)) (or (dom h1 h2) (eq t2 (mlstrustedobject)) ) ) $ sudo semodule -i test.cil zsh: segmentation fault sudo semodule -i test.cil This syntax is invalid and should error accordingly, rather than segfaulting. This patch provides this syntax error for the same module: $ sudo semodule -i test.cil t1, t2, r1, r2, u1, u2 cannot be used on the left side with a list on the right side Bad expression tree for constraint Bad constrain declaration at /var/lib/selinux/mls/tmp/modules/400/test/cil:4 semodule: Failed!

Build dependencies on Fedora: yum install audit-libs-devel bison bzip2-devel dbus-devel dbus-glib-devel flex flex-devel flex-static glib2-devel libcap-devel libcap-ng-devel pam-devel pcre-devel python3-devel python3-setools swig xmlto redhat-rpm-config To build and install everything under a private directory, run: make DESTDIR=~/obj install install-pywrap 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. To install libsepol on macOS (mainly for policy analysis): cd libsepol; make PREFIX=/usr/local install This requires GNU coreutils (brew install coreutils).
