Details

In the Linux kernel, the following vulnerability has been resolved:

net: netdevsim: don't try to destroy PHC on VFs

PHC gets initialized in nsiminitnetdevsim(), which is only called if (nsimdevportispf()).

Create a counterpart of nsiminitnetdevsim() and move the mockphcdestroy() there.

This fixes a crash trying to destroy netdevsim with VFs instantiated, as caught by running the devlink.sh test:

BUG: kernel NULL pointer dereference, address: 00000000000000b8
