As a non-root user:
a. I can't do readlink() on /proc/1/exe ("ls -l /proc/1/exe") b. I can do "cat /proc/1/maps" to see what files are mapped
That's backwards. If a user can read /proc/1/cmdline, then they might as well be permitted to readlink() on /proc/1/exe as well. Reading /proc/1/maps is quite another matter, exposing more info than the (prohibited) /proc/1/fd/* does. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
