Hi, folks,

I applied DES's patch to CURRENT and see if my VMWare runs, but it
caused panic.

After investigation of kernel core, I found that DES's patch has
problem when non-socket fd is passed to ioctl(SIOCGIFFLAGS).

SIOCGIFFLAGS (linux_gifflags()) assumes that ifp is not NULL, but if
type is not socket, ifp is left NULL.

How should this be fixed?

Regards,
