Dimitry Andric <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Dimitry Andric <[email protected]> --- Bisection shows this was introduced by r271396 [1]. Specifically, this part that was added: 2572 if (ifp != NULL && ( 2573 ND_IFINFO(ifp)->flags & ND6_IFF_IFDISABLED)) 2574 return (ENETDOWN); The problem is that ND_IFINFO(ifp) dereferences ifp->if_afdata[AF_INET6] unconditionally, so if that is NULL, a page fault occurs. Maybe a good fix is just the following?
