Modules

  • validation 🔒
    This module contains functions that help us validate the inputs to system calls that try to make sure userspace can’t crash or exploit the kernel in any way. For example, if we take an address from userspace, we should make sure it’s mapped (so we don’t page-fault) and an address that userspace could ordinarily access itself (otherwise, we could leak information to a userspace task that it shouldn’t be able to access).
