Hmm...the restorecon fix has been in policy for a while now, so if you
have the latest policy, you shouldn't still be seeing those denials; I
don't see them with current rawhide.  There was a change made to the
restorecon code that creates a child process and communicates with it
via a pipe, which is why it suddenly started needing that permission.
But that was added to the policy as I noted.

There were other policy fixes associated with the other items you
mentioned as well.

rpm -q selinux-policy-targeted
rpm -V selinux-policy-targeted
