hello According to http://lwn.net/Articles/104415/, Fedora Core started to use a patch to secure /dev/mem. I would like to know where to get that patch? Here is the excerpt from the mentioned paper: "Arjan van de Ven's patch which keeps processes from being able to overwrite kernel memory via /dev/mem. This patch has been shipped with Red Hat/Fedora kernels for a while, but is not yet in the mainline". Thank you a lot, AQ -- Kernelnewbies: Help each other learn about the Linux kernel.
