I did what can to bullet proof the code so that it does not stomp on the wrong device driver. Written and tested under 4.1.3u1 -Pete shipley () dis orgAntiHijacking tool? It disables sun4's kernel ability to modload modules on fly, thus also disables things like ppp, slip, et al. I won't call it a solution.
Also note that there's nothing to stop someone opening /dev/kmem and putting the correct cdevsw[] entries back in place. If you dont need loadable modules, they're safer out of your kernel. If you do need them, better stop people fucking about with /dev/kmem after you've disabled them via this method. -- ------------------------------------------+----------------------------------- Mailed using ELM on FreeBSD | Karl Strickland PGP 2.3a Public Key Available. | Internet: karl () bagpuss demon co uk |
