c7c88e998a First round of IIO new device support, features and cleanups for the 4.10 cycle.
Fair number of outreachy related patches in here. Some of these may well
 have already been picked up by Greg but git will sort that out for us.
 
 Also some good staging cleanup work from other sources. Thanks Brian and Lars
 in particular for this.
 
 New device support
 * ACCES 104-quad-8
   - New driver for this 8 channel encoder input board. Lots of new ABI with
     this one.
 * AD7766
   - New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and
     AD7767-2 24 bit ADCs.
 * dmard 10
   - New driver for this 3 axis accelerometer.
 * Honeywell ABP pressure sensors.
   - New driver covering 56 parts in this series (too many to list here!)
 * HTS221
   - New driver to support this relative humidiy and temperature device.
 * LMP91000
   - New driver for this potentiostat (form of chemical sensor). Nice example
     of use of the buffered consumer interfaces and the use of a consumer
     provided trigger.
 * MiraMEMS DA311
   - New driver for this 3 axis accelerometer.
 * MiraMEMS DA280
   - New driver for this 3 axis accelerometer. Follow up caught up with
   vendor prefixes for these.
 
 Staging graduations
 * isl29018 light sensor
   - Fixes and cleanups listed below (thanks for your hard work on this Brian!)
 * sca3000
   - Fixes and cleanups listed below.  This was one of the small set of drivers
   that went into staging when IIO was first added.  Turns out it had a few
   bugs and needed to be brought into the modern era!  Not clear if I am
   the only person who actually has one of these still wired to a board.
 
 New features (Core)
  - Add an iio_trigger_validate_own_device helper which relies on the device
    and trigger having the same parent.  Convenient to have this for some
    of the more complex trigger / device interactions. Was hand rolled in
    a few drivers already so good to bring it into the core.
  - Add an iio_read_channel_offset in kernel access helper (similar to
    the existing one for scale).
  - IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros.  These
    lead some rather contrived function naming, but there is no denying they
    do reduced boilerplate.  I'm going to resist their introduction in
    drivers 'unless' they form part of a larger set of cleanups.
  - Counter channel type and index type.
 
 New features (Drivers)
 * hdc100x
   - Triggered buffer support.
 * mcp4725
   - Device tree bindings and support.
   - Voltage reference selection.
 * ti-adc0832
   - Triggered buffer support.
 * ti-adc161s626
   - Add regulator support allowing _scale and _offset values to be established
   and exported.
 
 New features (Tools)
 * iio_generic_buffer
   - -A option to force enable all channels rather than faulting if some are
   already enabled (like -a does).  Followup patches tidied this support up.
 
 Cleanups (Core)
  - Use kmalloc_array in iio_scan_mask_set.
  - Take event_attrs field of iio_info structure constant
  - Staging todo list updates. Most of it was long done.
  - MAINTAINERS had a wrong directory listing.
 
 Cleanups (Drivers)
 * Missing i2c trivial devices entries.
 * ad5592r
   - Fix an endian type related sparse warnings.
 * ad7150
   - Constify the event attribute_group structures.
 * ad7152
   - Add some blank lines to improve readability.
   - Sampling frequency control via chan-info element rather than hand rolled
   attributes.
   - add a new lock to avoid use of mlock for non state change related locking.
 * ad7280
   - Constify atrribute_group structure (second patch covers the event ones)
 * ad7606 (Lars is driving most of the cleanup on this with some additions from
   Eva)
   - Fix improper setting of oversampling pins.  This has been broken a very
   long time in this staging driver, so not going to push this back to stable.
   - Implement oversampling configuration via the chan_info mask element.
   - Remove an unused int_vref_mv field.
   - Remove a reundant name field from ad7606_chip_info.
   - Remove default device configuration from platform_data in favour of
   whatever the power on defaults are.
   - Remove out of band error reporting in the kernel log as not providing
   much information.
   - Fix oversampling ratio by having 1 be the value for no oversampling.
   - Avoid allocating buffer for each data capture.
   - Factor out common code between periodic and one-shot capture.
   - Move set_drvdat into common code.
   - Let the common probe function return int rather than jumping through
   an ERR_PTR.
   - Pass struct device * into common remove to simplify code.
   - Always run trigger handler only once per event (no one can remember why
   it was being possibly done twice).
   - Move over to the GPIO descriptor API to shorten and clarify code.
   - Move the buffer code into the main file as it's not optional and is
   now rather short in this driver.
   - Fix the naming of the supply regulator.
   - Rework regulator handling to handle errors including deferred probing.
   - Tidy up a ptr_err or 0 return.
 * ad7746
   - Sampling frequency control via info_mask element rather than hand rolled
 * ad7758
   - Sampling frequency control via info_mask element rather than hand rolled
   attributes.
 * ad7816
   - Constify the event attribute_group structure.
 * adt7316
   - Constify the event attribute group structures.
 * ak8974
   - Cleanup some sparse warnings about endian types.
 * ak8975
   - Cleanup some sparse warnings about endian types.
 * bmi160
   - Spare endian warning cleanups.
 * isl29018 (towards staging graduation)
   - Remove unusedvariables and defines.
   - Improve consistency of error handling.
   - Signed / unsigned comparison fixes.
   - Use the IIO_DEVICE_ATTR_{RO, RW} macros
   - Fix a race in in_illuminance_scale_available_show.
   - Cleanup exit points of _read_raw
   - Sanity check if in suspended state during a write_raw call as was already
     done for read_raw.
   - Document device tree bidnings.
   - Document infrared supression controls.
   - Add some newlines to improve readability and drop one that shouldn't be
     there.
   - Fix a poorly named functions name.
   - Fix multiline coment syntax.
   - Tidy up a pair or return statements by unifying them.
   - Rename description in Kconfig for consistency with similar drivers.
 * lidar
   - cleanup power management by dropping unnecessary call.
 * ltr501
   - Use the claim_direct_mode helpers. Fix a race condition along the way.
 * max1027
   - Fix a dubious x | !y sparse warning.
   - Use the new iio_trigger_validate_own_device helper.
 * max440000
   - Clean up some sparse warnings about endian types.
 * mcp4725
   - Use the regulator framework to establish the reference voltage rather than
     getting it from platform data.
   - Tidy up a comment typo.
   - Fix a wrong PTR_ERR query (wrong regulator).
 * mma7660
   - Take a mma7660_nscale static.
 * mma8452
   - Use the new iio_trigger_validate_own_device helper.
   - Use claim_direct_mode helpers - fix a race condition along the way.
 * mpl3115
   - Use claim_direct_mode helpers - fix a race condition along the way.
 * ms65611
   - Tidy up regulator error handling and clean out a static warning in the mix.
 * sca3000
   - Avoid a potential unitialized variable if a hardware read returns a value
   that isn't actually supported (mostly warning supression).
   - Fix a use before setting of the indio_dev->buffer pointer. Broken for
   a very long time so not going to rush this into stable.
   - Merge buffer file with core file.  We used to always split these.
   Sometimes it's just not worth the hassle. In this case the device's main
   feature is it's hardware fifos so unlikely anyone would want to run it
   without.
   - Drop the sca3000_register_ring_funcs function as it's a pointless wrapper
   once we have only one file.
   - Fix cleaning of flag + setting of size of scan. Without this you can't
   start the buffer twice and expect sensible (or any) results.  Again,
   broken for a long time so not heading for stable.
   - Drop the custom watershed setting ABI - for now we'll just support one
   value.
   - Move to a hybrid hard / soft buffer design (how we've been doing it
   for similar devices for a while now!)
   - Cleanup some unusued variables.
   - Use a fake channel to support core handling of freefall event registration.
   - Cleanup the register defines.
   - Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value.
   Been broken since first admission of IIO to the staging tree.
   - Add readback of the 3db low pass filter frequency and later writing
     allowing droppign of custom measurement mode attributes as they can
     be represented by the filter choices that is their main characteristic.
   - Drop non standard revision attr and replace with dev_info on probe.
   - Avoid a race in probe.
   - Various formatting fixes.
   - Kernel-docify docs that were very nearly in the write format.
 * tsl2583
   - Constify attribute_group structure.
 * zpa2326
   - Drop a redundant DEBUG ifdef.
 
 Cleanups (Tools)
 * iio_generic_buffer
   - Fix the ? arguement. Previously it sort of worked as you got the help
     message as a result of it not recognising the arguement.

2778556474 Some RDMA work and some good bugfixes, and two new features that could
benefit from user testing:
 
 Anna Schumacker contributed a simple NFSv4.2 COPY implementation.  COPY
 is already supported on the client side, so a call to copy_file_range()
 on a recent client should now result in a server-side copy that doesn't
 require all the data to make a round trip to the client and back.
 
 Jeff Layton implemented callbacks to notify clients when contended locks
 become available, which should reduce latency on workloads with
 contended locks.

Pull XFS support for shared data extents from Dave Chinner:
 "This is the second part of the XFS updates for this merge cycle.  This
  pullreq contains the new shared data extents feature for XFS.

  Given the complexity and size of this change I am expecting - like the
  addition of reverse mapping last cycle - that there will be some
  follow-up bug fixes and cleanups around the -rc3 stage for issues that
  I'm sure will show up once the code hits a wider userbase.

  What it is:

  At the most basic level we are simply adding shared data extents to
  XFS - i.e. a single extent on disk can now have multiple owners. To do
  this we have to add new on-disk features to both track the shared
  extents and the number of times they've been shared. This is done by
  the new "refcount" btree that sits in every allocation group. When we
  share or unshare an extent, this tree gets updated.

  Along with this new tree, the reverse mapping tree needs to be updated
  to track each owner or a shared extent. This also needs to be updated
  ever share/unshare operation. These interactions at extent allocation
  and freeing time have complex ordering and recovery constraints, so
  there's a significant amount of new intent-based transaction code to
  ensure that operations are performed atomically from both the runtime
  and integrity/crash recovery perspectives.

  We also need to break sharing when writes hit a shared extent - this
  is where the new copy-on-write implementation comes in. We allocate
  new storage and copy the original data along with the overwrite data
  into the new location. We only do this for data as we don't share
  metadata at all - each inode has it's own metadata that tracks the
  shared data extents, the extents undergoing CoW and it's own private
  extents.

  Of course, being XFS, nothing is simple - we use delayed allocation
  for CoW similar to how we use it for normal writes. ENOSPC is a
  significant issue here - we build on the reservation code added in
  4.8-rc1 with the reverse mapping feature to ensure we don't get
  spurious ENOSPC issues part way through a CoW operation. These
  mechanisms also help minimise fragmentation due to repeated CoW
  operations. To further reduce fragmentation overhead, we've also
  introduced a CoW extent size hint, which indicates how large a region
  we should allocate when we execute a CoW operation.

  With all this functionality in place, we can hook up .copy_file_range,
  .clone_file_range and .dedupe_file_range and we gain all the
  capabilities of reflink and other vfs provided functionality that
  enable manipulation to shared extents. We also added a fallocate mode
  that explicitly unshares a range of a file, which we implemented as an
  explicit CoW of all the shared extents in a file.

  As such, it's a huge chunk of new functionality with new on-disk
  format features and internal infrastructure. It warns at mount time as
  an experimental feature and that it may eat data (as we do with all
  new on-disk features until they stabilise). We have not released
  userspace suport for it yet - userspace support currently requires
  download from Darrick's xfsprogs repo and build from source, so the
  access to this feature is really developer/tester only at this point.
  Initial userspace support will be released at the same time the kernel
  with this code in it is released.

  The new code causes 5-6 new failures with xfstests - these aren't
  serious functional failures but things the output of tests changing
  slightly due to perturbations in layouts, space usage, etc. OTOH,
  we've added 150+ new tests to xfstests that specifically exercise this
  new functionality so it's got far better test coverage than any
  functionality we've previously added to XFS.

  Darrick has done a pretty amazing job getting us to this stage, and
  special mention also needs to go to Christoph (review, testing,
  improvements and bug fixes) and Brian (caught several intricate bugs
  during review) for the effort they've also put in.

  Summary:

   - unshare range (FALLOC_FL_UNSHARE) support for fallocate

   - copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr
     interface

   - shared extent support for XFS

d09ba13110 libnvdimm for 4.9
* PMEM sub-division support: Allow a single PMEM region to be divided
   into multiple namespaces. Originally, ~2 years ago, it was thought that
   partitions of a /dev/pmemX block device could handle sub-allocations of
   persistent memory for different use cases. With the decision to not
   support DAX mappings of raw block-devices, and the genesis of
   device-dax, the need for having multiple pmem-namespace per region has
   grown.
 
 * Device-DAX unified inode: In support of dynamic-resizing of a
   device-dax instance the kernel arranges for all mappings of a
   device-dax node to share the same inode. This allows unmap / truncate /
   invalidation events to affect all instances of the device similar to the
   behavior of mmap on block devices.
 
 * Hardware error scrubbing reworks: The original address-range-scrub +
   badblocks tracking solution allowed clearing entries at the individual
   namespace level, but it failed to clear the internal list of media
   errors maintained at the bus level. The result was that the next scrub
   or namespace disable/re-enable event would restore the cleared
   badblocks, but now that is fixed. The v4.8 kernel introduced an
   auto-scrub-on-machine-check behavior to repopulate the badblocks list.
   Now, in v4.9, the auto-scrub behavior can be disabled and simply arrange
   for the error reported in the machine-check to be added to the list.
 
 * DIMM health-event notification support: ACPI 6.1 defines a
   notification event code that can be send to ACPI NVDIMM devices. A
   poll(2) capable file descriptor for these events can be obtained from
   the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory device.
 
 * Miscellaneous fixes: NVDIMM-N probe error, device-dax build error, and
   a change to dedup the flush hint list to not flush the memory controller
   more than necessary.

Pull HID updates from Jiri Kosina:

 - Integrated Sensor Hub support (Cherrytrail+) from Srinivas Pandruvada

 - Big cleanup of Wacom driver; namely it's now using devres, and the
   standardized LED API so that libinput doesn't need to have root
   access any more, with substantial amount of other cleanups
   piggy-backing on top. All this from Benjamin Tissoires

 - Report descriptor parsing would now ignore and out-of-range System
   controls in case of the application actually being System Control.
   This fixes quite some issues with several devices, and allows us to
   remove a few ->report_fixup callbacks. From Benjamin Tissoires

 - ... a lot of other assorted small fixes and device ID additions

14986a34e1 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
 "This set of changes is a number of smaller things that have been
  overlooked in other development cycles focused on more fundamental
  change. The devpts changes are small things that were a distraction
  until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an
  trivial regression fix to autofs for the unprivileged mount changes
  that went in last cycle. A pair of ioctls has been added by Andrey
  Vagin making it is possible to discover the relationships between
  namespaces when referring to them through file descriptors.

  The big user visible change is starting to add simple resource limits
  to catch programs that misbehave. With namespaces in general and user
  namespaces in particular allowing users to use more kinds of
  resources, it has become important to have something to limit errant
  programs. Because the purpose of these limits is to catch errant
  programs the code needs to be inexpensive to use as it always on, and
  the default limits need to be high enough that well behaved programs
  on well behaved systems don't encounter them.

  To this end, after some review I have implemented per user per user
  namespace limits, and use them to limit the number of namespaces. The
  limits being per user mean that one user can not exhause the limits of
  another user. The limits being per user namespace allow contexts where
  the limit is 0 and security conscious folks can remove from their
  threat anlysis the code used to manage namespaces (as they have
  historically done as it root only). At the same time the limits being
  per user namespace allow other parts of the system to use namespaces.

  Namespaces are increasingly being used in application sand boxing
  scenarios so an all or nothing disable for the entire system for the
  security conscious folks makes increasing use of these sandboxes
  impossible.

  There is also added a limit on the maximum number of mounts present in
  a single mount namespace. It is nontrivial to guess what a reasonable
  system wide limit on the number of mount structure in the kernel would
  be, especially as it various based on how a system is using
  containers. A limit on the number of mounts in a mount namespace
  however is much easier to understand and set. In most cases in
  practice only about 1000 mounts are used. Given that some autofs
  scenarious have the potential to be 30,000 to 50,000 mounts I have set
  the default limit for the number of mounts at 100,000 which is well
  above every known set of users but low enough that the mount hash
  tables don't degrade unreaonsably.

  These limits are a start. I expect this estabilishes a pattern that
  other limits for resources that namespaces use will follow. There has
  been interest in making inotify event limits per user per user
  namespace as well as interest expressed in making details about what
  is going on in the kernel more visible"

6675df311d Btrfs: catch invalid free space trees
There are two separate issues that can lead to corrupted free space
trees.

1. The free space tree bitmaps had an endianness issue on big-endian
   systems which is fixed by an earlier patch in this series.
2. btrfs-progs before v4.7.3 modified filesystems without updating the
   free space tree.

To catch both of these issues at once, we need to force the free space
tree to be rebuilt. To do so, add a FREE_SPACE_TREE_VALID compat_ro bit.
If the bit isn't set, we know that it was either produced by a broken
big-endian kernel or may have been corrupted by btrfs-progs.

This also provides us with a way to add rudimentary read-write support
for the free space tree to btrfs-progs: it can just clear this bit and
have the kernel rebuild the free space tree.

8e5470c983 serial: 8250: Set Altera 16550 TX FIFO Threshold
The Altera 16550 soft IP UART requires 2 additional registers for
TX FIFO threshold support. These 2 registers enable the TX FIFO
Low Watermark and set the TX FIFO Low Watermark.
Set the TX FIFO threshold to the FIFO size - tx_loadsz.

8564e38206 cfg80211: add checks for beacon rate, extend to mesh
The previous commit added support for specifying the beacon rate
for AP mode. Add features checks to this, and extend it to also
support the rate configuration for mesh networks. For IBSS it's
not as simple due to joining etc., so that's not yet supported.

ff107d2776 netfilter: nft_log: complete NFTA_LOG_FLAGS attr support
NFTA_LOG_FLAGS attribute is already supported, but the related
NF_LOG_XXX flags are not exposed to the userspace. So we cannot
explicitly enable log flags to log uid, tcp sequence, ip options
and so on, i.e. such rule "nft add rule filter output log uid"
is not supported yet.

So move NF_LOG_XXX macro definitions to the uapi/../nf_log.h. In
order to keep consistent with other modules, change NF_LOG_MASK to
refer to all supported log flags. On the other hand, add a new
NF_LOG_DEFAULT_MASK to refer to the original default log flags.

Finally, if user specify the unsupported log flags or NFTA_LOG_GROUP
and NFTA_LOG_FLAGS are set at the same time, report EINVAL to the
userspace.

0f3cd9b369 netfilter: nf_tables: add range expression
Inverse ranges != [a,b] are not currently possible because rules are
composites of && operations, and we need to express this:

	data < a || data > b

This patch adds a new range expression. Positive ranges can be already
through two cmp expressions:

	cmp(sreg, data, >=)
	cmp(sreg, data, <=)

This new range expression provides an alternative way to express this.

11d5f15723 netfilter: xt_hashlimit: Create revision 2 to support higher pps rates
Create a new revision for the hashlimit iptables extension module. Rev 2
will support higher pps of upto 1 million, Version 1 supports only 10k.

To support this we have to increase the size of the variables avg and
burst in hashlimit_cfg to 64-bit. Create two new structs hashlimit_cfg2
and xt_hashlimit_mtinfo2 and also create newer versions of all the
functions for match, checkentry and destroy.

Some of the functions like hashlimit_mt, hashlimit_mt_check etc are very
similar in both rev1 and rev2 with only minor changes, so I have split
those functions and moved all the common code to a *_common function.

79aab093a0 net: Update API for VF vlan protocol 802.1ad support
Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.

For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.

Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
  Set vf vlan protocol 802.1ad:
    ip link set eth0 vf 1 vlan 100 proto 802.1ad
  Set vf to VST (802.1Q) mode:
    ip link set eth0 vf 1 vlan 100 proto 802.1Q
  Or by omitting the new parameter
    ip link set eth0 vf 1 vlan 100
