While reviewing the code of umount_tree I realized that when we append
to a preexisting unmounted list we do not change pprev of the former
first item in the list.

Which means later in namespace_unlock hlist_del_init(&mnt->mnt_hash) on
the former first item of the list will stomp unmounted.first leaving
it set to some random mount point which we are likely to free soon.

This isn't likely to hit, but if it does I don't know how anyone could
track it down.

[ This happened because we don't have all the same operations for
  hlist's as we do for normal doubly-linked lists. In particular,
  list_splice() is easy on our standard doubly-linked lists, while
  hlist_splice() doesn't exist and needs both start/end entries of the
  hlist.  And commit 38129a13 incorrectly open-coded that missing
  hlist_splice().

  We should think about making these kinds of "mindless" conversions
  easier to get right by adding the missing hlist helpers   - Linus ]

Commit bc96f648 (xen-netback: make
feature-rx-notify mandatory) incorrectly assumed that there were no
frontends in use that did not support this feature.  But the frontend
driver in MiniOS does not and since this is used by (qemu) stubdoms,
these stopped working.

Netback sort of works as-is in this mode except:

- If there are no Rx requests and the internal Rx queue fills, only
  the drain timeout will wake the thread.  The default drain timeout
  of 10 s would give unacceptable pauses.

- If an Rx stall was detected and the internal Rx queue is drained,
  then the Rx thread would never wake.

Handle these two cases (when feature-rx-notify is disabled) by:

- Reducing the drain timeout to 30 ms.

- Disabling Rx stall detection.

Currently, searching for a socket to add a reference to is not
synchronized with deletion of sockets. This can result in use
after free if there is another operation that is removing a
socket at the same time. Solving this requires both holding the
appropriate lock and checking the refcount to ensure that it
has not already hit zero.

Each mmap Netlink frame contains a status field which indicates
whether the frame is unused, reserved, contains data or needs to
be skipped. Both loads and stores may not be reordeded and must
complete before the status field is changed and another CPU might
pick up the frame for use. Use an smp_mb() to cover needs of both
types of callers to netlink_set_status(), callers which have been
reading data frame from the frame, and callers which have been
filling or releasing and thus writing to the frame.

- Example code path requiring a smp_rmb():
  memcpy(skb->data, (void *)hdr + NL_MMAP_HDRLEN, hdr->nm_len);
  netlink_set_status(hdr, NL_MMAP_STATUS_UNUSED);

Pull user namespace related fixes from Eric Biederman:
 "As these are bug fixes almost all of thes changes are marked for
  backporting to stable.

  The first change (implicitly adding MNT_NODEV on remount) addresses a
  regression that was created when security issues with unprivileged
  remount were closed.  I go on to update the remount test to make it
  easy to detect if this issue reoccurs.

  Then there are a handful of mount and umount related fixes.

  Then half of the changes deal with the a recently discovered design
  bug in the permission checks of gid_map.  Unix since the beginning has
  allowed setting group permissions on files to less than the user and
  other permissions (aka ---rwx---rwx).  As the unix permission checks
  stop as soon as a group matches, and setgroups allows setting groups
  that can not later be dropped, results in a situtation where it is
  possible to legitimately use a group to assign fewer privileges to a
  process.  Which means dropping a group can increase a processes
  privileges.

  The fix I have adopted is that gid_map is now no longer writable
  without privilege unless the new file /proc/self/setgroups has been
  set to permanently disable setgroups.

  The bulk of user namespace using applications even the applications
  using applications using user namespaces without privilege remain
  unaffected by this change.  Unfortunately this ix breaks a couple user
  space applications, that were relying on the problematic behavior (one
  of which was tools/selftests/mount/unprivileged-remount-test.c).

  To hopefully prevent needing a regression fix on top of my security
  fix I rounded folks who work with the container implementations mostly
  like to be affected and encouraged them to test the changes.

The optimization for filtering out extended inquiry results, advertising
reports or scan response data based on provided UUID list has a logic
bug. In case no match is found in the advertising data, the scan
response is ignored and not checked against the filter. This will lead
to events being filtered wrongly.

Change the code to actually only drop the events when the scan response
data is not present. If it is present, it needs to be checked against
the provided filter.

The patch is a bit more complex than it needs to be. That is because
it also fixes this compiler warning that some gcc versions produce.

  CC      net/bluetooth/mgmt.o
net/bluetooth/mgmt.c: In function ‘mgmt_device_found’:
net/bluetooth/mgmt.c:7028:7: warning: ‘match’ may be used uninitialized in this function [-Wmaybe-uninitialized]
  bool match;
       ^

It seems that gcc can not clearly figure out the context of the match
variable. So just change the branches for the extended inquiry response
and advertising data around so that it is clear.

Dave Hansen reports that commit fb7332a9 ("mmu_gather: move minimal

  "tlb_finish_mmu() goes up about 9x in the profiles (~0.4%->3.6%) and
   tlb_flush_mmu_free() takes about 3.1% of CPU time with the patch
   applied, but does not show up at all on the commit before"

and the reason is that Will moved the test for whether we need to flush
from tlb_flush_mmu() into tlb_flush_mmu_tlbonly().  But that meant that
tlb_flush_mmu_free() basically lost that check.

Move it back into tlb_flush_mmu() where it belongs, so that it covers
both tlb_flush_mmu_tlbonly() _and_ tlb_flush_mmu_free().

Pull input subsystem updates from Dmitry Torokhov:
 "Two new drivers for Elan hardware (for I2C touchpad and touchscreen
  found in several Chromebooks and other devices), a driver for Goodix
  touch panel, and small fixes to Cypress I2C trackpad and other input
  drivers.

  Also we switched to use __maybe_unused instead of gating suspend/
  resume code with #ifdef guards to get better compile coverage"

Pull MTD updates from Brian Norris:
 "Summary:
   - Add device tree support for DoC3

   - SPI NOR:
        Refactoring, for better layering between spi-nor.c and its
        driver users (e.g., m25p80.c)

        New flash device support

        Support 6-byte ID strings

   - NAND:
        New NAND driver for Allwinner SoC's (sunxi)

        GPMI NAND: add support for raw (no ECC) access, for testing
        purposes

        Add ATO manufacturer ID

        A few odd driver fixes
