      ipc/sem.c: Fix missing wakeups in do_smart_update_queue() · ab465df9
      Manfred Spraul 提交于
      do_smart_update_queue() is called when an operation (semop,
      semctl(SETVAL), semctl(SETALL), ...) modified the array.  It must check
      which of the sleeping tasks can proceed.
      
      do_smart_update_queue() missed a few wakeups:
       - if a sleeping complex op was completed, then all per-semaphore queues
         must be scanned - not only those that were modified by *sops
       - if a sleeping simple op proceeded, then the global queue must be
         scanned again
      
      And:
       - the test for "|sops == NULL) before scanning the global queue is not
         required: If the global queue is empty, then it doesn't need to be
         scanned - regardless of the reason for calling do_smart_update_queue()
      
      The patch is not optimized, i.e.  even completing a wait-for-zero
      operation causes a rescan.  This is done to keep the patch as simple as
      possible.

      ARC: lazy dcache flush broke gdb in non-aliasing configs · 7bb66f6e
      Vineet Gupta 提交于
      gdbserver inserting a breakpoint ends up calling copy_user_page() for a
      code page. The generic version of which (non-aliasing config) didn't set
      the PG_arch_1 bit hence update_mmu_cache() didn't sync dcache/icache for
      corresponding dynamic loader code page - causing garbade to be executed.
      
      So now aliasing versions of copy_user_highpage()/clear_page() are made
      default. There is no significant overhead since all of special alias
      handling code is compiled out for non-aliasing build

      aio: fix kioctx not being freed after cancellation at exit time · 03e04f04
      Benjamin LaHaise 提交于
      The recent changes overhauling fs/aio.c introduced a bug that results in
      the kioctx not being freed when outstanding kiocbs are cancelled at
      exit_aio() time.  Specifically, a kiocb that is cancelled has its
      completion events discarded by batch_complete_aio(), which then fails to
      wake up the process stuck in free_ioctx().  Fix this by modifying the
      wait_event() condition in free_ioctx() appropriately.
      
      This patch was tested with the cancel operation in the thread based code
      posted yesterday.

      mm/pagewalk.c: walk_page_range should avoid VM_PFNMAP areas · a9ff785e
      Cliff Wickman 提交于
      A panic can be caused by simply cat'ing /proc/<pid>/smaps while an
      application has a VM_PFNMAP range.  It happened in-house when a
      benchmarker was trying to decipher the memory layout of his program.
      
      /proc/<pid>/smaps and similar walks through a user page table should not
      be looking at VM_PFNMAP areas.
      
      Certain tests in walk_page_range() (specifically split_huge_page_pmd())
      assume that all the mapped PFN's are backed with page structures.  And
      this is not usually true for VM_PFNMAP areas.  This can result in panics
      on kernel page faults when attempting to address those page structures.
      
      There are a half dozen callers of walk_page_range() that walk through a
      task's entire page table (as N.  Horiguchi pointed out).  So rather than
      change all of them, this patch changes just walk_page_range() to ignore
      VM_PFNMAP areas.
      
      The logic of hugetlb_vma() is moved back into walk_page_range(), as we
      want to test any vma in the range.
      
      VM_PFNMAP areas are used by:
      - graphics memory manager   gpu/drm/drm_gem.c
      - global reference unit     sgi-gru/grufile.c
      - sgi special memory        char/mspec.c
      - and probably several out-of-tree modules
