    [$] Keeping secrets in memfd areas
    Back in November 2019, Mike Rapoport made
    the case
    that there is too much address-space sharing in Linux
    systems. This sharing can be convenient and good for performance, but in
    an era of advanced attacks and hardware vulnerabilities it also facilitates
    security problems. At that time, he proposed a number of possible changes
    in general terms; he has now come back with a patch
    implementing a couple of address-space isolation options for the memfd mechanism. This work demonstrates the
    sort of features we may be seeing, but some of the hard work has been left
    for the future.
