      thp: close race between split and zap huge pages · b5a8cad3
      Kirill A. Shutemov authored
      Sasha Levin has reported two THP BUGs[1][2].  I believe both of them
      have the same root cause.  Let's look to them one by one.
      
      The first bug[1] is "kernel BUG at mm/huge_memory.c:1829!".  It's
      BUG_ON(mapcount != page_mapcount(page)) in __split_huge_page().  From my
      testing I see that page_mapcount() is higher than mapcount here.
      
      I think it happens due to race between zap_huge_pmd() and
      page_check_address_pmd().  page_check_address_pmd() misses PMD which is
      under zap:
      
      	CPU0						CPU1
      						zap_huge_pmd()
      						  pmdp_get_and_clear()
      __split_huge_page()
        anon_vma_interval_tree_foreach()
          __split_huge_page_splitting()
            page_check_address_pmd()
              mm_find_pmd()
      	  /*
      	   * We check if PMD present without taking ptl: no
      	   * serialization against zap_huge_pmd(). We miss this PMD,
      	   * it's not accounted to 'mapcount' in __split_huge_page().
      	   */
      	  pmd_present(pmd) == 0
      
        BUG_ON(mapcount != page_mapcount(page)) // CRASH!!!
      
      						  page_remove_rmap(page)
      						    atomic_add_negative(-1, &page->_mapcount)
      
      The second bug[2] is "kernel BUG at mm/huge_memory.c:1371!".
      It's VM_BUG_ON_PAGE(!PageHead(page), page) in zap_huge_pmd().
      
      This happens in similar way:
      
      	CPU0						CPU1
      						zap_huge_pmd()
      						  pmdp_get_and_clear()
      						  page_remove_rmap(page)
      						    atomic_add_negative(-1, &page->_mapcount)
      __split_huge_page()
        anon_vma_interval_tree_foreach()
          __split_huge_page_splitting()
            page_check_address_pmd()
              mm_find_pmd()
      	  pmd_present(pmd) == 0	/* The same comment as above */
        /*
         * No crash this time since we already decremented page->_mapcount in
         * zap_huge_pmd().
         */
        BUG_ON(mapcount != page_mapcount(page))
      
        /*
         * We split the compound page here into small pages without
         * serialization against zap_huge_pmd()
         */
        __split_huge_page_refcount()
      						VM_BUG_ON_PAGE(!PageHead(page), page); // CRASH!!!
      
      So my understanding the problem is pmd_present() check in mm_find_pmd()
      without taking page table lock.
      
      The bug was introduced by me commit with commit 117b0791. Sorry for
      that. :(
      
      Let's open code mm_find_pmd() in page_check_address_pmd() and do the
      check under page table lock.
      
      Note that __page_check_address() does the same for PTE entires
      if sync != 0.
      
      I've stress tested split and zap code paths for 36+ hours by now and
      don't see crashes with the patch applied. Before it took <20 min to
      trigger the first bug and few hours for second one (if we ignore
      first).

      mm: use paravirt friendly ops for NUMA hinting ptes · 29c77870
      Mel Gorman authored
      David Vrabel identified a regression when using automatic NUMA balancing
      under Xen whereby page table entries were getting corrupted due to the
      use of native PTE operations.  Quoting him
      
      	Xen PV guest page tables require that their entries use machine
      	addresses if the preset bit (_PAGE_PRESENT) is set, and (for
      	successful migration) non-present PTEs must use pseudo-physical
      	addresses.  This is because on migration MFNs in present PTEs are
      	translated to PFNs (canonicalised) so they may be translated back
      	to the new MFN in the destination domain (uncanonicalised).
      
      	pte_mknonnuma(), pmd_mknonnuma(), pte_mknuma() and pmd_mknuma()
      	set and clear the _PAGE_PRESENT bit using pte_set_flags(),
      	pte_clear_flags(), etc.
      
      	In a Xen PV guest, these functions must translate MFNs to PFNs
      	when clearing _PAGE_PRESENT and translate PFNs to MFNs when setting
      	_PAGE_PRESENT.
      
      His suggested fix converted p[te|md]_[set|clear]_flags to using
      paravirt-friendly ops but this is overkill.  He suggested an alternative
      of using p[te|md]_modify in the NUMA page table operations but this is
      does more work than necessary and would require looking up a VMA for
      protections.
      
      This patch modifies the NUMA page table operations to use paravirt
      friendly operations to set/clear the flags of interest.  Unfortunately
      this will take a performance hit when updating the PTEs on
      CONFIG_PARAVIRT but I do not see a way around it that does not break
      Xen.

      mips: export flush_icache_range · 8229f1a0
      Kees Cook authored
      The lkdtm module performs tests against executable memory ranges, so it
      needs to flush the icache for proper behaviors.  Other architectures
      already export this, so do the same for MIPS.

      Documentation/vm/numa_memory_policy.txt: fix wrong document in numa_memory_policy.txt · 8f28ed92
      Tang Chen authored
      In document numa_memory_policy.txt, the following examples for flag
      MPOL_F_RELATIVE_NODES are incorrect.
      
      	For example, consider a task that is attached to a cpuset with
      	mems 2-5 that sets an Interleave policy over the same set with
      	MPOL_F_RELATIVE_NODES.  If the cpuset's mems change to 3-7, the
      	interleave now occurs over nodes 3,5-6.  If the cpuset's mems
      	then change to 0,2-3,5, then the interleave occurs over nodes
      	0,3,5.
      
      According to the comment of the patch adding flag MPOL_F_RELATIVE_NODES,
      the nodemasks the user specifies should be considered relative to the
      current task's mems_allowed.
      
       (https://lkml.org/lkml/2008/2/29/428)
      
      And according to numa_memory_policy.txt, if the user's nodemask includes
      nodes that are outside the range of the new set of allowed nodes, then
      the remap wraps around to the beginning of the nodemask and, if not
      already set, sets the node in the mempolicy nodemask.
      
      So in the example, if the user specifies 2-5, for a task whose
      mems_allowed is 3-7, the nodemasks should be remapped the third, fourth,
      fifth, sixth node in mems_allowed.  like the following:
      
      	mems_allowed:       3  4  5  6  7
      
      	relative index:     0  1  2  3  4
      	                    5
      
      So the nodemasks should be remapped to 3,5-7, but not 3,5-6.
      
      And for a task whose mems_allowed is 0,2-3,5, the nodemasks should be
      remapped to 0,2-3,5, but not 0,3,5.
      
      	mems_allowed:       0  2  3  5
      
              relative index:     0  1  2  3
                                  4  5

      init/Kconfig: move the trusted keyring config option to general setup · 82c04ff8
      Peter Foley authored
      The SYSTEM_TRUSTED_KEYRING config option is not in any menu, causing it
      to show up in the toplevel of the kernel configuration.  Fix this by
      moving it under the General Setup menu.

      vmscan: reclaim_clean_pages_from_list() must use mod_zone_page_state() · 83da7510
      Christoph Lameter authored
      Seems to be called with preemption enabled.  Therefore it must use
      mod_zone_page_state instead.
