      powerpc: get_hugepte() don't put_page() the wrong page · 405e44f2
      Andrea Arcangeli authored
      
      
      "page" may have changed to point to the next hugepage after the loop
      completed, The references have been taken on the head page, so the
      put_page must happen there too.
      
      This is a longstanding issue pre-thp inclusion.
      
      It's totally unclear how these page_cache_add_speculative and
      pte_val(pte) != pte_val(*ptep) checks are necessary across all the
      powerpc gup_fast code, when x86 doesn't need any of that: there's no way
      the page can be freed with irq disabled so we're guaranteed the
      atomic_inc will happen on a page with page_count > 0 (so not needing the
      speculative check).
      
      The pte check is also meaningless on x86: no need to rollback on x86 if
      the pte changed, because the pte can still change a CPU tick after the
      check succeeded and it won't be rolled back in that case.  The important
      thing is we got a reference on a valid page that was mapped there a CPU
      tick ago.  So not knowing the soft tlb refill code of ppc64 in great
      detail I'm not removing the "speculative" page_count increase and the
      pte checks across all the code, but unless there's a strong reason for
      it they should be later cleaned up too.
      
      If a pte can change from huge to non-huge (like it could happen with
      THP) passing a pte_t *ptep to gup_hugepte() would also require to repeat
      the is_hugepd in gup_hugepte(), but that shouldn't happen with hugetlbfs
      only so I'm not altering that.

      powerpc: remove superfluous PageTail checks on the pte gup_fast · 2839bdc1
      Andrea Arcangeli authored
      
      
      This part of gup_fast doesn't seem capable of handling hugetlbfs ptes,
      those should be handled by gup_hugepd only, so these checks are
      superfluous.
      
      Plus if this wasn't a noop, it would have oopsed because, the insistence
      of using the speculative refcounting would trigger a VM_BUG_ON if a tail
      page was encountered in the page_cache_get_speculative().

      mm: thp: tail page refcounting fix · 70b50f94
      Andrea Arcangeli authored
      
      
      Michel while working on the working set estimation code, noticed that
      calling get_page_unless_zero() on a random pfn_to_page(random_pfn)
      wasn't safe, if the pfn ended up being a tail page of a transparent
      hugepage under splitting by __split_huge_page_refcount().
      
      He then found the problem could also theoretically materialize with
      page_cache_get_speculative() during the speculative radix tree lookups
      that uses get_page_unless_zero() in SMP if the radix tree page is freed
      and reallocated and get_user_pages is called on it before
      page_cache_get_speculative has a chance to call get_page_unless_zero().
      
      So the best way to fix the problem is to keep page_tail->_count zero at
      all times.  This will guarantee that get_page_unless_zero() can never
      succeed on any tail page.  page_tail->_mapcount is guaranteed zero and
      is unused for all tail pages of a compound page, so we can simply
      account the tail page references there and transfer them to
      tail_page->_count in __split_huge_page_refcount() (in addition to the
      head_page->_mapcount).
      
      While debugging this s/_count/_mapcount/ change I also noticed get_page is
      called by direct-io.c on pages returned by get_user_pages.  That wasn't
      entirely safe because the two atomic_inc in get_page weren't atomic.  As
      opposed to other get_user_page users like secondary-MMU page fault to
      establish the shadow pagetables would never call any superflous get_page
      after get_user_page returns.  It's safer to make get_page universally safe
      for tail pages and to use get_page_foll() within follow_page (inside
      get_user_pages()).  get_page_foll() is safe to do the refcounting for tail
      pages without taking any locks because it is run within PT lock protected
      critical sections (PT lock for pte and page_table_lock for
      pmd_trans_huge).
      
      The standard get_page() as invoked by direct-io instead will now take
      the compound_lock but still only for tail pages.  The direct-io paths
      are usually I/O bound and the compound_lock is per THP so very
      finegrined, so there's no risk of scalability issues with it.  A simple
      direct-io benchmarks with all lockdep prove locking and spinlock
      debugging infrastructure enabled shows identical performance and no
      overhead.  So it's worth it.  Ideally direct-io should stop calling
      get_page() on pages returned by get_user_pages().  The spinlock in
      get_page() is already optimized away for no-THP builds but doing
      get_page() on tail pages returned by GUP is generally a rare operation
      and usually only run in I/O paths.
      
      This new refcounting on page_tail->_mapcount in addition to avoiding new
      RCU critical sections will also allow the working set estimation code to
      work without any further complexity associated to the tail page
      refcounting with THP.
