Problem was that it was filed in bugzilla a while back but, initially, under iptables and then redirected to the kernel guys who threw their hands up saying, "well, it's experimental and not enabled". Bug is still open, AFAIK. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=209945 I guess the finger pointing stopped at that point and everyone dropped the ball. It wasn't clear (to me at least) that should have been against s-c-securitylevel, or that I needed to file another bugzilla filing, and there's been discussion on the lists and in bugzilla about it. Caught me by surprise when the fix was announced and the package the fix was announced in. From the last message in Bugzilla on that bug: > Noted, and thank you for the amplifying information.
