      Merge tag 'libnvdimm-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm · 9b06860d
      Linus Torvalds authored
      Pull libnvdimm and dax updates from Dan Williams:
       "There were multiple touches outside of drivers/nvdimm/ this round to
        add cross arch compatibility to the devm_memremap_pages() interface,
        enhance numa information for persistent memory ranges, and add a
        zero_page_range() dax operation.
        This cycle I switched from the patchwork api to Konstantin's b4 script
        for collecting tags (from x86, PowerPC, filesystem, and device-mapper
        folks), and everything looks to have gone ok there. This has all
        appeared in -next with no reported issues.
         - Add support for region alignment configuration and enforcement to
           fix compatibility across architectures and PowerPC page size
         - Introduce 'zero_page_range' as a dax operation. This facilitates
           filesystem-dax operation without a block-device.
         - Introduce phys_to_target_node() to facilitate drivers that want to
           know resulting numa node if a given reserved address range was
         - Advertise a persistence-domain for of_pmem and papr_scm. The
           persistence domain indicates where cpu-store cycles need to reach
           in the platform-memory subsystem before the platform will consider
           them power-fail protected.
         - Promote numa_map_to_online_node() to a cross-kernel generic
         - Save x86 numa information to allow for node-id lookups for reserved
           memory ranges, deploy that capability for the e820-pmem driver.
         - Pick up some miscellaneous minor fixes, that missed v5.6-final,
           including a some smatch reports in the ioctl path and some unit
           test compilation fixups.
         - Fixup some flexible-array declarations"

      mm/gup: Let __get_user_pages_locked() return -EINTR for fatal signal · ae46d2aa

      4426e945 ("mm/gup: allow VM_FAULT_RETRY for multiple times") which
      added extra code to allow gup detect fatal signal faster.
      Restore the original -EINTR behavior.

      mm/gup: Mark lock taken only after a successful retake · c7b6a566
      Peter Xu authored
      It's definitely incorrect to mark the lock as taken even if
      down_read_killable() failed.
      This wass overlooked when we switched from down_read() to
      down_read_killable() because down_read() won't fail while
      down_read_killable() could.

      mm/mempolicy: Allow lookup_node() to handle fatal signal · ba841078
      Peter Xu authored
      lookup_node() uses gup to pin the page and get node information.  It
      checks against ret>=0 assuming the page will be filled in.  However it's
      also possible that gup will return zero, for example, when the thread is
      quickly killed with a fatal signal.  Teach lookup_node() to gracefully
      return an error -EFAULT if it happens.
      Meanwhile, initialize "page" to NULL to avoid potential risk of
      exploiting the pointer.

      ubsan: include bug type in report header · ef065653
      Kees Cook authored
      When syzbot tries to figure out how to deduplicate bug reports, it prefers
      seeing a hint about a specific bug type (we can do better than just
      "UBSAN").  This lifts the handler reason into the UBSAN report line that
      includes the file path that tripped a check.  Unfortunately, UBSAN does
      not provide function names.

      As done in the full WARN() handler, panic_on_warn needs to be cleared
      before calling panic() to avoid recursive panics.

      Kees Cook authored
      Syzkaller expects kernel warnings to panic when the panic_on_warn sysctl
      is set.  More work is needed here to have UBSan reuse the WARN
      infrastructure, but for now, just check the flag manually.
