+Subject: [PATCH] libselinux: Use Python distutils to install SELinux python
+ bindings
+
+Follow officially documented way how to build C extension modules using
+distutils - https://docs.python.org/3.8/extending/building.html#building
+
+Fixes:
+
+- selinux python module fails to load when it's built using SWIG-4.0:
+
+>>> import selinux
+Traceback (most recent call last):
+ File "<stdin>", line 1, in <module>
+ File "/usr/lib64/python3.7/site-packages/selinux/__init__.py", line 13, in <module>
+ from . import _selinux
+ImportError: cannot import name '_selinux' from 'selinux' (/usr/lib64/python3.7/site-packages/selinux/__init__.py)
+
+SWIG-4.0 changed (again?) its behavior so that it uses: from . import _selinux
+which looks for _selinux module in the same directory as where __init__.py is -
+$(PYLIBDIR)/site-packages/selinux. But _selinux module is installed into
+$(PYLIBDIR)/site-packages/ since a9604c30a5e2f ("libselinux: Change the location
+of _selinux.so").
+
+- audit2why python module fails to build with Python 3.8
+
+cc -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -DOVERRIDE_GETTID=0 -I../include -D_GNU_SOURCE -DDISABLE_RPM -DNO_ANDROID_BACKEND -DUSE_PCRE2 -DPCRE2_CODE_UNIT_WIDTH=8 -Wl,-z,relro -Wl,--as-needed -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -L. -shared -o python-3.8audit2why.so python-3.8audit2why.lo -lselinux -l:libsepol.a -Wl,-soname,audit2why.so,--version-script=audit2why.map,-z,defs
+/usr/bin/ld: python-3.8audit2why.lo: in function `finish':
+/builddir/build/BUILD/libselinux-2.9/src/audit2why.c:166: undefined reference to `PyArg_ParseTuple'
+/usr/bin/ld: python-3.8audit2why.lo: in function `_Py_INCREF':
+/usr/include/python3.8/object.h:449: undefined reference to `_Py_NoneStruct'
+/usr/bin/ld: /usr/include/python3.8/object.h:449: undefined reference to `_Py_NoneStruct'
+/usr/bin/ld: python-3.8audit2why.lo: in function `check_booleans':
+/builddir/build/BUILD/libselinux-2.9/src/audit2why.c:84: undefined reference to `PyExc_RuntimeError'
+...
+
+It's related to the following Python change
+https://docs.python.org/dev/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build
+
+Python distutils adds correct link options automatically.
+
+- selinux python module doesn't provide any Python metadata
+
+When selinux python module was built manually, it didn't provide any metadata.
+distutils takes care about that so that selinux Python module is visible for
+pip:
+
+$ pip3 list | grep selinux
+selinux 2.9
