As long as a certain process p is running, there’s no possibility of altering its
FDT externally. Our project tries to solve this issue using GNU/Linux Kernel
aids, developing a Linux Kernel Module (LKM) which can alter any process FDT
at runtime, with no need of killing the process nor modifying its source code. This
way, our LKM can insert a new File Descriptor, say fd’, inside the process FDT,
exchanging <FDT[fd],FDT[fd’]> whenever a non-root user decides.
