Python import selinux

I am getting this, on a RHEL 6.8 machine:

[fast@pandora]$ python
Python 2.6.6 (r266:84292, Aug  9 2016, 06:11:56)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import selinux
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.6/site-packages/selinux/__init__.py", line 25, in <module>
    _selinux = swig_import_helper()
  File "/usr/lib64/python2.6/site-packages/selinux/__init__.py", line 21, in swig_import_helper
    _mod = imp.load_module('_selinux', fp, pathname, description)
ImportError: /usr/lib64/python2.6/site-packages/selinux/_selinux.so: undefined symbol: selinux_set_policy_root
>>>

Can anyone shed some light? The following is the output of the installed selinux packages:

[fast@pandora]$ yum list installed | grep selinux

Bugs in the RHEL packages should be filed at bugzilla.redhat.com, not here - this issue tracker is for issues with the upstream selinux code. I can't reproduce your issue with the upstream selinux code. libselinux 2.0.94 was from the 20100525 release of selinux. selinux_set_policy_root() was not introduced until 2013. I assume Red Hat back-ported a patch incorrectly, introducing a caller of the function without the function's definition, but I don't really know. This assumes of course that you are using the pristine RHEL packages and not some locally customized one.

Works for me.

libselinux.x86_64          2.0.94-5.3.el6_4.1   installed
libselinux.x86_64          2.0.94-7.el6         @rhel-x86_64-server-6.8-20160802

I guess it's a conflict among those 2 packages as selinux_set_policy_root was added to libselinux-2.0.94-6.el6. Please remove the older one and try it again.

@bachradsusi that is the fix. Thanks!
