Daniel Cashman <dcashman@android.com> discovered the following: When using cil_db multiple_decls, the different cil_attribute nodes all point to the same underlying cil_attribute struct. This leads to problems, though, when modifying the used value in the struct. __cil_post_db_attr() changes the value of the field to based on the output of cil_typeattribute_used(), for use later in cil_typeattribute_to_policydb and cil_typeattribute_to_bitmap, but due to the multiple declarations, cil_typeattribute_used() could be called again by a second node. In this second call, the value used is the modifed value of CIL_TRUE or CIL_FALSE, not the flags actually needed. This could result in the field being reset again, to an incorrect CIL_FALSE value. Add the field "keep" to struct cil_typeattributeset, set its value using cil_typeattribute_used(), and use it when determining whether the attribute is to be kept or if it should be expanded.

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 python-devel setools-devel 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 DESTDIR=/usr/local PREFIX=/usr/local install This requires GNU coreutils (brew install coreutils).
