--- Comment #12 from Mark Johnston <ma...@freebsd.org> ---
I think I agree with the proposed patch to use VMIO_SIOCSIFFLAGS. Even if IP
is disabled on the jail, tap is an L2 device. The fact that we have to use an
IP socket to configure the interface is bizarre; this overloading of sockets is
also problematic for capsicum.
OTOH, I think we can configure IFF_UP with any kind of socket, no? We could
use a PF_ROUTE or PF_NETLINK socket instead. I don't think netlink itself buys
us anything here, ifconfig still uses socket ioctls to set interface flags.
One other reason to avoid VMIO_SIOCSIFFLAGS is that it's really just there for
vmnet(4) compatibility, I believe.
