      Linus Torvalds authored
      Pull pidfd system call from Christian Brauner:
       "This introduces the ability to use file descriptors from /proc/<pid>/
        as stable handles on struct pid. Even if a pid is recycled the handle
        will not change. For a start these fds can be used to send signals to
        the processes they refer to.
        With the ability to use /proc/<pid> fds as stable handles on struct
        pid we can fix a long-standing issue where after a process has exited
        its pid can be reused by another process. If a caller sends a signal
        to a reused pid it will end up signaling the wrong process.
        With this patchset we enable a variety of use cases. One obvious
        example is that we can now safely delegate an important part of
        process management - sending signals - to processes other than the
        parent of a given process by sending file descriptors around via scm
        rights and not fearing that the given process will have been recycled
        in the meantime. It also allows for easy testing whether a given
        process is still alive or not by sending signal 0 to a pidfd which is
        quite handy.
        There has been some interest in this feature e.g. from systems
        management (systemd, glibc) and container managers. I have requested
        and gotten comments from glibc to make sure that this syscall is
        suitable for their needs as well. In the future I expect it to take on
        most other pid-based signal syscalls. But such features are left for
        the future once they are needed.
        This has been sitting in linux-next for quite a while and has not
        caused any issues. It comes with selftests which verify basic
        functionality and also test that a recycled pid cannot be signaled via
        a pidfd.
        Jon has written about a prior version of this patchset. It should
        cover the basic functionality since not a lot has changed since then:
        The commit message for the syscall itself is extensively documenting
        the syscall, including it's functionality and extensibility"

      Linus Torvalds authored
      Pull device-dax updates from Dan Williams:
       "New device-dax infrastructure to allow persistent memory and other
        "reserved" / performance differentiated memories, to be assigned to
        the core-mm as "System RAM".
        Some users want to use persistent memory as additional volatile
        memory. They are willing to cope with potential performance
        differences, for example between DRAM and 3D Xpoint, and want to use
        typical Linux memory management apis rather than a userspace memory
        allocator layered over an mmap() of a dax file. The administration
        model is to decide how much Persistent Memory (pmem) to use as System
        RAM, create a device-dax-mode namespace of that size, and then assign
        it to the core-mm. The rationale for device-dax is that it is a
        generic memory-mapping driver that can be layered over any "special
        purpose" memory, not just pmem. On subsequent boots udev rules can be
        used to restore the memory assignment.
        One implication of using pmem as RAM is that mlock() no longer keeps
        data off persistent media. For this reason it is recommended to enable
        NVDIMM Security (previously merged for 5.0) to encrypt pmem contents
        at rest. We considered making this recommendation an actively enforced
        requirement, but in the end decided to leave it as a distribution /
        administrator policy to allow for emulation and test environments that
        lack security capable NVDIMMs.
         - Replace the /sys/class/dax device model with /sys/bus/dax, and
           include a compat driver so distributions can opt-in to the new ABI.
         - Allow for an alternative driver for the device-dax address-range
         - Introduce the 'kmem' driver to hotplug / assign a device-dax
           address-range to the core-mm.
         - Arrange for the device-dax target-node to be onlined so that the
           newly added memory range can be uniquely referenced by numa apis"
      NOTE! I'm not entirely happy with the whole "PMEM as RAM" model because
      we currently have special - and very annoying rules in the kernel about
      accessing PMEM only with the "MC safe" accessors, because machine checks
      inside the regular repeat string copy functions can be fatal in some
      (not described) circumstances.
      And apparently the PMEM modules can cause that a lot more than regular
      RAM.  The argument is that this happens because PMEM doesn't necessarily
      get scrubbed at boot like RAM does, but that is planned to be added for
      the user space tooling.
      Quoting Dan from another email:
       "The exposure can be reduced in the volatile-RAM case by scanning for
        and clearing errors before it is onlined as RAM. The userspace tooling
        for that can be in place before v5.1-final. There's also runtime
        notifications of errors via acpi_nfit_uc_error_notify() from
        background scrubbers on the DIMM devices. With that mechanism the
        kernel could proactively clear newly discovered poison in the volatile
        case, but that would be additional development more suitable for v5.2.
        I understand the concern, and the need to highlight this issue by
        tapping the brakes on feature development, but I don't see PMEM as RAM
        making the situation worse when the exposure is also there via DAX in
        the PMEM case. Volatile-RAM is arguably a safer use case since it's
        possible to repair pages where the persistent case needs active
        application coordination"
