Hi there, Due to a problem I've had in a program, I pose the question described below. I have an application that uses the proc filesystem to gather information about the local network interfaces. Those functions check proc/net for _not_ being a symlink; this could possibly mean a rerouted directory (with malicious intentions). Allthough, as of Linux-2.6.25, the proc/net directory has been assigned being a pointer to proc/self/net and my program fails. I now either have to remove the link-check or alternatively implement my function (by means of IOCTL's for example). I was wondering; isn't it dangerous to do this? I'm not sure whether it is actually doable to reroute proc/* directories/files...What's your thought?
