    [$] The state of guest_memfd

    Date:
    Fri, 04 Apr 2025 15:52:32 +0000

    Description:
    A typical cloud-computing host will share some of its memory with each
    guest that it runs. The host retains its access to that memory, though, meaning that it can readily dig through that memory in search of data that
    the guest would prefer to keep private. The guest_memfd subsystem removes (most of) the
    host's access to guest memory, making the guest's data more secure. In the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, David Hildenbrand ran a discussion on
    the state and future of this feature.
