      Freezer: avoid freezing kernel threads prematurely · 0c1eecfb
      Rafael J. Wysocki authored
      Kernel threads should not have TIF_FREEZE set when user space processes are
      being frozen, since otherwise some of them might be frozen prematurely.
      To prevent this from happening we can (1) make exit_mm() unset TIF_FREEZE
      unconditionally just after clearing tsk->mm and (2) make try_to_freeze_tasks()
      check if p->mm is different from zero and PF_BORROWED_MM is unset in p->flags
      when user space processes are to be frozen.
      
      Namely, when user space processes are being frozen, we only should set
      TIF_FREEZE for tasks that have p->mm different from NULL and don't have
      PF_BORROWED_MM set in p->flags.  For this reason task_lock() must be used to
      prevent try_to_freeze_tasks() from racing with use_mm()/unuse_mm(), in which
      p->mm and p->flags.PF_BORROWED_MM are changed under task_lock(p).  Also, we
      need to prevent the following scenario from happening:
      
      * daemonize() is called by a task spawned from a user space code path
      * freezer checks if the task has p->mm set and the result is positive
      * task enters exit_mm() and clears its TIF_FREEZE
      * freezer sets TIF_FREEZE for the task
      * task calls try_to_freeze() and goes to the refrigerator, which is wrong at
        that point
      
      This requires us to acquire task_lock(p) before p->flags.PF_BORROWED_MM and
      p->mm are examined and release it after TIF_FREEZE is set for p (or it turns
      out that TIF_FREEZE should not be set).

      Hibernation: prepare to enter the low power state · b1457bcc
      Rafael J. Wysocki authored
      During hibernation we call hibernation_ops->prepare() before creating the image,
      but then, before saving it, we cancel the power transition by calling
      hibernation_ops->finish().  Thus prior to calling hibernation_ops->enter() we
      should let the platform firmware know that we're going to enter the low power
      state after all.

      swsusp: fix hibernation code ordering · 10a1803d
      Rafael J. Wysocki authored
      Change the code ordering so that hibernation_ops->prepare() is called after
      device_suspend().  This is needed so that we don't violate the ACPI
      specification, which states that the _PTS and _GTS system-control methods,
      executed from acpi_sleep_prepare(), ought to be called after devices have been
      put in low power states.
      
      The "Finish" label in hibernation_restore() is moved, because device_suspend()
      resumes devices if the suspending of them fails and the restore code ordering
      should reflect the hibernation code ordering.

      swsusp: introduce restore platform operations · a634cc10
      Rafael J. Wysocki authored
      At least on some machines it is necessary to prepare the ACPI firmware for the
      restoration of the system memory state from the hibernation image if the
      "platform" mode of hibernation has been used.  Namely, in that cases we need
      to disable the GPEs before replacing the "boot" kernel with the "frozen"
      kernel (cf.  http://bugzilla.kernel.org/show_bug.cgi?id=7887).  After the
      restore they will be re-enabled by hibernation_ops->finish(), but if the
      restore fails, they have to be re-enabled by the restore code explicitly.
      
      For this purpose we can introduce two additional hibernation operations,
      called pre_restore() and restore_cleanup() and call them from the restore code
      path.  Still, they should be called if the "platform" mode of hibernation has
      been used, so we need to pass the information about the hibernation mode from
      the "frozen" kernel to the "boot" kernel in the image header.
      
      Apparently, we can't drop the disabling of GPEs before the restore because of
      Bug #7887 .   We also can't do it unconditionally, because the GPEs wouldn't
      have been enabled after a successful restore if the suspend had been done in
      the 'shutdown' or 'reboot' mode.
      
      In principle we could (and probably should) unconditionally disable the GPEs
      before each snapshot creation *and* before the restore, but then we'd have to
      unconditionally enable them after the snapshot creation as well as after the
      restore (or restore failure)   Still, for this purpose we'd need to modify
      acpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we'd have to
      introduce some mechanism synchronizing the disablind/enabling of the GPEs with
      the device drivers' .suspend()/.resume() routines and with
      disable_/enable_nonboot_cpus().   However, this would have affected the
      suspend (ie.  s2ram) code as well as the hibernation, which I'd like to avoid
      in this patch series.

      swsusp: remove incorrect code from user.c · 127067a9
      Rafael J. Wysocki authored
      In the face of the recent change of suspend code ordering (cf.
      http://marc.info/?l=linux-acpi&m=117938245931603&w=2) we should also modify
      the code ordering in swsusp so that hibernation_ops->prepare() is executed
      after device_suspend().
      
      However, for this purpose it seems reasonable to eliminate the code
      duplication between kernel/power/disk.c and kernel/power/user.c first.  By
      eliminating it we can reduce the size of user.c quite substantially and remove
      the maintenance difficulty with making essentially the same changes in two
      different places.
      
      Moreover, we should also remove the calls to "platform" functions from the
      restore code path, since it doesn't carry out any power transition of the
      system, but we generally need to disable the GPEs before the restore if the
      'platform' hibernation mode has been used.  To do this, we can introduce two
      new hibernation_ops to be used in the restore code.
      
      This patch:
      
      Make the code hibernation code in kernel/power/user.c be functionally
      equivalent to the corresponding code in kernel/power/disk.c , as it should be.
      
      The calls to the platform functions removed by this patch are incorrect.  They
      should be replaced with some other "platform" invocations that will be
      introduced in one of the subsequent patches.

      only allow nonlinear vmas for ram backed filesystems · 3ee6dafc
      Miklos Szeredi authored
      page_mkclean() doesn't re-protect ptes for non-linear mappings, so a later
      re-dirty through such a mapping will not generate a fault, PG_dirty will
      not reflect the dirty state and the dirty count will be skewed.  This
      implies that msync() is also currently broken for nonlinear mappings.
      
      The easiest solution is to emulate remap_file_pages on non-linear mappings
      with simple mmap() for non ram-backed filesystems.  Applications continue
      to work (albeit slower), as long as the number of remappings remain below
      the maximum vma count.
      
      However all currently known real uses of non-linear mappings are for ram
      backed filesystems, which this patch doesn't affect.

      Nick Piggin authored
      Change ->fault prototype.  We now return an int, which contains
      VM_FAULT_xxx code in the low byte, and FAULT_RET_xxx code in the next byte.
       FAULT_RET_ code tells the VM whether a page was found, whether it has been
      locked, and potentially other things.  This is not quite the way he wanted
      it yet, but that's changed in the next patch (which requires changes to
      arch code).
      
      This means we no longer set VM_CAN_INVALIDATE in the vma in order to say
      that a page is locked which requires filemap_nopage to go away (because we
      can no longer remain backward compatible without that flag), but we were
      going to do that anyway.
      
      struct fault_data is renamed to struct vm_fault as Linus asked. address
      is now a void __user * that we should firmly encourage drivers not to use
      without really good reason.
      
      The page is now returned via a page pointer in the vm_fault struct.

      mm: merge populate and nopage into fault (fixes nonlinear) · 54cb8821
      Nick Piggin authored
      Nonlinear mappings are (AFAIKS) simply a virtual memory concept that encodes
      the virtual address -> file offset differently from linear mappings.
      
      ->populate is a layering violation because the filesystem/pagecache code
      should need to know anything about the virtual memory mapping.  The hitch here
      is that the ->nopage handler didn't pass down enough information (ie.  pgoff).
       But it is more logical to pass pgoff rather than have the ->nopage function
      calculate it itself anyway (because that's a similar layering violation).
      
      Having the populate handler install the pte itself is likewise a nasty thing
      to be doing.
      
      This patch introduces a new fault handler that replaces ->nopage and
      ->populate and (later) ->nopfn.  Most of the old mechanism is still in place
      so there is a lot of duplication and nice cleanups that can be removed if
      everyone switches over.
      
      The rationale for doing this in the first place is that nonlinear mappings are
      subject to the pagefault vs invalidate/truncate race too, and it seemed stupid
      to duplicate the synchronisation logic rather than just consolidate the two.
      
      After this patch, MAP_NONBLOCK no longer sets up ptes for pages present in
      pagecache.  Seems like a fringe functionality anyway.
      
      NOPAGE_REFAULT is removed.  This should be implemented with ->fault, and no
      users have hit mainline yet.

      mm: fix fault vs invalidate race for linear mappings · d00806b1
      Nick Piggin authored
      Fix the race between invalidate_inode_pages and do_no_page.
      
      Andrea Arcangeli identified a subtle race between invalidation of pages from
      pagecache with userspace mappings, and do_no_page.
      
      The issue is that invalidation has to shoot down all mappings to the page,
      before it can be discarded from the pagecache.  Between shooting down ptes to
      a particular page, and actually dropping the struct page from the pagecache,
      do_no_page from any process might fault on that page and establish a new
      mapping to the page just before it gets discarded from the pagecache.
      
      The most common case where such invalidation is used is in file truncation.
      This case was catered for by doing a sort of open-coded seqlock between the
      file's i_size, and its truncate_count.
      
      Truncation will decrease i_size, then increment truncate_count before
      unmapping userspace pages; do_no_page will read truncate_count, then find the
      page if it is within i_size, and then check truncate_count under the page
      table lock and back out and retry if it had subsequently been changed (ptl
      will serialise against unmapping, and ensure a potentially updated
      truncate_count is actually visible).
      
      Complexity and documentation issues aside, the locking protocol fails in the
      case where we would like to invalidate pagecache inside i_size.  do_no_page
      can come in anytime and filemap_nopage is not aware of the invalidation in
      progress (as it is when it is outside i_size).  The end result is that
      dangling (->mapping == NULL) pages that appear to be from a particular file
      may be mapped into userspace with nonsense data.  Valid mappings to the same
      place will see a different page.
      
      Andrea implemented two working fixes, one using a real seqlock, another using
      a page->flags bit.  He also proposed using the page lock in do_no_page, but
      that was initially considered too heavyweight.  However, it is not a global or
      per-file lock, and the page cacheline is modified in do_no_page to increment
      _count and _mapcount anyway, so a further modification should not be a large
      performance hit.  Scalability is not an issue.
      
      This patch implements this latter approach.  ->nopage implementations return
      with the page locked if it is possible for their underlying file to be
      invalidated (in that case, they must set a special vm_flags bit to indicate
      so).  do_no_page only unlocks the page after setting up the mapping
      completely.  invalidation is excluded because it holds the page lock during
      invalidation of each page (and ensures that the page is not mapped while
      holding the lock).
      
      This also allows significant simplifications in do_no_page, because we have
      the page locked in the right place in the pagecache from the start.
