I attempted to restart the gif0 interface of zyxomma after correcting the tunnel endpoint. The kernel panicked. I got a crash dump. It is the 0th in my home directory on leaf. Here is the traceback:

This is a 64-bit box using a gif interface for a he.net tunnel.

Setting the sysctl node net.route.assert_owner_access to 0 should prevent this particular panic.
This is not a real fix, howewer.
