           Summary: Selinux enhanced file rights not handled correctly
    Classification: Platform
           Product: GStreamer
           Version: 2.x
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: kasberger at heidenhain.de
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


Following steps to reproduce
1. Installing Fluendo Code package
2. Enable Selinux
3. run gst-inspect-1.0
4. now all newy added codecs are blacklisted because we have not relabled the
new installation
5. Disable Selinux
6. run gst-inspect will not change anything because files are unchanged and
already on blacklist

Only deleting the registry would help.

Correct handling would be in
gst/gstregistry.c in function gst_registry_scan_path_level

and add in the checks for regular file

if (access(filename,X_OK)!=0) {
      GST_TRACE_OBJECT (context->registry, "%s file status SeLinux executable
file, ignoring",
          filename);
      g_free (filename);
      continue;
    }

So we check if the file is executable ( normal file rights and SeLinux). If not
executable we just ignore it. 
Tested on Linux it is working.
