      libnvdimm: prevent nvdimm from requesting key when security is disabled · 674f31a3
      Dave Jiang authored
      Current implementation attempts to request keys from the keyring even when
      security is not enabled. Change behavior so when security is disabled it
      will skip key request.
      
      Error messages seen when no keys are installed and libnvdimm is loaded:
      
          request-key[4598]: Cannot find command to construct key 661489677

      libnvdimm/region: Initialize bad block for volatile namespaces · c42adf87
      Aneesh Kumar K.V authored
      We do check for a bad block during namespace init and that use
      region bad block list. We need to initialize the bad block
      for volatile regions for this to work. We also observe a lockdep
      warning as below because the lock is not initialized correctly
      since we skip bad block init for volatile regions.
      
       INFO: trying to register non-static key.
       the code is fine but needs lockdep annotation.
       turning off the locking correctness validator.

      libnvdimm/altmap: Track namespace boundaries in altmap · cf387d96
      Aneesh Kumar K.V authored
      With PFN_MODE_PMEM namespace, the memmap area is allocated from the device
      area. Some architectures map the memmap area with large page size. On
      architectures like ppc64, 16MB page for memap mapping can map 262144 pfns.
      This maps a namespace size of 16G.
      
      When populating memmap region with 16MB page from the device area,
      make sure the allocated space is not used to map resources outside this
      namespace. Such usage of device area will prevent a namespace destroy.
      
      Add resource end pnf in altmap and use that to check if the memmap area
      allocation can map pfn outside the namespace. On ppc64 in such case we fallback
      to allocation from memory.
      
      This fix kernel crash reported below:

      libnvdimm/dax: Pick the right alignment default when creating dax devices · f5376699
      Aneesh Kumar K.V authored
      Allow arch to provide the supported alignments and use hugepage alignment only
      if we support hugepage. Right now we depend on compile time configs whereas this
      patch switch this to runtime discovery.
      
      Architectures like ppc64 can have THP enabled in code, but then can have
      hugepage size disabled by the hypervisor. This allows us to create dax devices
      with PAGE_SIZE alignment in this case.
      
      Existing dax namespace with alignment larger than PAGE_SIZE will fail to
      initialize in this specific case. We still allow fsdax namespace initialization.
      
      With respect to identifying whether to enable hugepage fault for a dax device,
      if THP is enabled during compile, we default to taking hugepage fault and in dax
      fault handler if we find the fault size > alignment we retry with PAGE_SIZE
      fault size.
      
      This also addresses the below failure scenario on ppc64

      Makefile: Convert -Wimplicit-fallthrough=3 to just -Wimplicit-fallthrough for clang · bfd77145
      Joe Perches authored
      A compilation -Wimplicit-fallthrough warning was enabled by commit
      a035d552 ("Makefile: Globally enable fall-through warning")
      
      Even though clang 10.0.0 does not currently support this warning without
      a patch, clang currently does not support a value for this option.
      
        Link: https://bugs.llvm.org/show_bug.cgi?id=39382
      
      The gcc default for this warning is 3 so removing the =3 has no effect
      for gcc and enables the warning for patched versions of clang.
      
      Also remove the =3 from an existing use in a parisc Makefile:
      arch/parisc/math-emu/Makefile
