      ACPICA: Tables: Fix regression introduced by a too early mechanism enabling · 2ea65321
      Lv Zheng authored
      In the Linux kernel, acpi_get_table() "clones" haven't been fully
      balanced by acpi_put_table() invocations.  In upstream ACPICA, due to
      the design change, there are also unbalanced acpi_get_table_by_index()
      invocations requiring special care.
      
      acpi_get_table() reference counting mismatches may occor due to that
      and printing error messages related to them is not useful at this
      point.  The strict balanced validation count check should only be
      enabled after confirming that all invocations are safe and aligned
      with their designed purposes.
      
      Thus this patch removes the error value returned by acpi_tb_get_table()
      in that case along with the accompanying error message to fix the
      issue.
      
      Fixes: 174cc718 (ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel)

      ACPICA: Add non-linux host build support · 6895baa6
      Lv Zheng authored
      _LINUX: used to detect a target build is a linux kernel/application.
      __linux__: used to detect a build is on a linux hosts.
      
      Thus we can see: if a linux kernel build is performed on environments other
      than linux hosts, __linux__ may not be defined by the compiler and _LINUX
      cannot cover linux kernel resident ACPICA files, as it's only defined in
      <linux/acpi.h> and hence only allows non ACPICA kernel files to correctly
      include aclinux.h.
      As a conclusion, we don't actually support such build.
      
      This patch adds -D_LINUX for ACPICA files so that kernel builds on any
      hosts can use unified _LINUX as a linux kernel target indication to
      correctly include aclinux.h.

       "Here's a pull request for 4.11-rc, fixing a set of issues mostly
        centered around the new scheduling framework. These have been brewing
        for a while, but split up into what we absolutely need in 4.11, and
        what we can defer until 4.12. These are well tested, on both single
        queue and multiqueue setups, and with and without shared tags. They
        fix several hangs that have happened in testing.
      
        This is obviously larger than I would have preferred at this point in
        time, but I don't think we can shave much off this and still get the
        desired results.
      
        In detail, this pull request contains:
      
         - a set of five fixes for NVMe, mostly from Christoph and one from
           Roland.
      
         - a series from Bart, fixing issues with dm-mq and SCSI shared tags
           and scheduling. Note that one of those patches commit messages may
           read like an optimization, but it is in fact an important fix for
           queue restarts in particular.
      
         - a series from Omar, most importantly fixing a hang with multiple
           hardware queues when we fail to get a driver tag. Another important
           fix in there is for resizing hardware queues, which nbd does when
           handling multiple sockets for one connection.

      sysfs: be careful of error returns from ops->show() · c8a139d0
      NeilBrown authored
      ops->show() can return a negative error code.
      Commit 65da3484 ("sysfs: correctly handle short reads on PREALLOC attrs.")
      (in v4.4) caused this to be stored in an unsigned 'size_t' variable, so errors
      would look like large numbers.
      As a result, if an error is returned, sysfs_kf_read() will return the
      value of 'count', typically 4096.
      
      Commit 17d0774f ("sysfs: correctly handle read offset on PREALLOC attrs")
      (in v4.8) extended this error to use the unsigned large 'len' as a size for
      memmove().
      Consequently, if ->show returns an error, then the first read() on the
      sysfs file will return 4096 and could return uninitialized memory to
      user-space.
      If the application performs a subsequent read, this will trigger a memmove()
      with extremely large count, and is likely to crash the machine is bizarre ways.
      
      This bug can currently only be triggered by reading from an md
      sysfs attribute declared with __ATTR_PREALLOC() during the
      brief period between when mddev_put() deletes an mddev from
      the ->all_mddevs list, and when mddev_delayed_delete() - which is
      scheduled on a workqueue - completes.
      Before this, an error won't be returned by the ->show()
      After this, the ->show() won't be called.
      
      I can reproduce it reliably only by putting delay like
      	usleep_range(500000,700000);
      early in mddev_delayed_delete(). Then after creating an
      md device md0 run
        echo clear > /sys/block/md0/md/array_state; cat /sys/block/md0/md/array_state
      
      The bug can be triggered without the usleep.

      vfs_llseek will check whether the file mode has
      FMODE_LSEEK, no return failure. But ashmem can be
      lseek, so add FMODE_LSEEK to ashmem file.
      
      Comment From Greg Hackmann:
      	ashmem_llseek() passes the llseek() call through to the backing
      	shmem file.  91360b02 ("ashmem: use vfs_llseek()") changed
      	this from directly calling the file's llseek() op into a VFS
      	layer call.  This also adds a check for the FMODE_LSEEK bit, so
      	without that bit ashmem_llseek() now always fails with -ESPIPE.

      Pull audit cleanup from Paul Moore:
       "A week later than I had hoped, but as promised, here is the audit
        uninline-fix we talked about during the last audit pull request.
      
        The patch is slightly different than what we originally discussed as
        it made more sense to keep the audit_signal_info() function in
        auditsc.c rather than move it and bunch of other related
        variables/definitions into audit.c/audit.h.
      
        At some point in the future I need to look at how the audit code is
        organized across kernel/audit*, I suspect we could do things a bit
        better, but it doesn't seem like a -rc release is a good place for
        that ;)
      
        Regardless, this patch passes our tests without problem and looks good
        for v4.11"

      mm: move pcp and lru-pcp draining into single wq · ce612879
      Michal Hocko authored
      We currently have 2 specific WQ_RECLAIM workqueues in the mm code.
      vmstat_wq for updating pcp stats and lru_add_drain_wq dedicated to drain
      per cpu lru caches.  This seems more than necessary because both can run
      on a single WQ.  Both do not block on locks requiring a memory
      allocation nor perform any allocations themselves.  We will save one
      rescuer thread this way.
      
      On the other hand drain_all_pages() queues work on the system wq which
      doesn't have rescuer and so this depend on memory allocation (when all
      workers are stuck allocating and new ones cannot be created).
      
      Initially we thought this would be more of a theoretical problem but
      Hugh Dickins has reported:
      
      : 4.11-rc has been giving me hangs after hours of swapping load.  At
      : first they looked like memory leaks ("fork: Cannot allocate memory");
      : but for no good reason I happened to do "cat /proc/sys/vm/stat_refresh"
      : before looking at /proc/meminfo one time, and the stat_refresh stuck
      : in D state, waiting for completion of flush_work like many kworkers.
      : kthreadd waiting for completion of flush_work in drain_all_pages().
      
      This worker should be using WQ_RECLAIM as well in order to guarantee a
      forward progress.  We can reuse the same one as for lru draining and
      vmstat.
