Linus Torvalds bafb0762cb Char/Misc drivers for 4.14-rc1
Here is the big char/misc driver update for 4.14-rc1.
 
 Lots of different stuff in here, it's been an active development cycle
 for some reason.  Highlights are:
   - updated binder driver, this brings binder up to date with what
     shipped in the Android O release, plus some more changes that
     happened since then that are in the Android development trees.
   - coresight updates and fixes
   - mux driver file renames to be a bit "nicer"
   - intel_th driver updates
   - normal set of hyper-v updates and changes
   - small fpga subsystem and driver updates
   - lots of const code changes all over the driver trees
   - extcon driver updates
   - fmc driver subsystem upadates
   - w1 subsystem minor reworks and new features and drivers added
   - spmi driver updates
 
 Plus a smattering of other minor driver updates and fixes.
 
 All of these have been in linux-next with no reported issues for a
 while.

Linus Torvalds bf1d6b2c76 Staging/IIO driver updates for 4.14-rc1
Here is the big staging and IIO driver update for 4.14-rc1.
 
 Lots of staging driver fixes and cleanups, including some reorginizing
 of the lustre header files to try to impose some sanity on what is, and
 what is not, the uapi for that filesystem.
 
 There are some tty core changes in here as well, as the speakup drivers
 need them, and that's ok with me, they are sane and the speakup code is
 getting nicer because of it.
 
 There is also the addition of the obiligatory new wifi driver, just
 because it has been a release or two since we added our last one...
 
 Other than that, lots and lots of small coding style fixes, as usual.
 
 All of these have been in linux-next for a while with no reported
 issues.

Bernat, Yehezkel e545f0d8a5 thunderbolt: Allow clearing the key
If secure authentication of a devices fails, either because the device
already has another key uploaded, or there is some other error sending
challenge to the device, and the user only wants to approve the device
just once (without a new key being uploaded to the device) the current
implementation does not allow this because the key cannot be cleared
once set even if we allow it to be changed.

Make this scenario possible and allow clearing the key by writing
empty string to the key sysfs file.

Jack Pham f624ec70b4 usb: misc: lvstest: add entry to place port in compliance mode
Add support for the SuperSpeed Link Layer test case TD.7.34
which requires the operator to place the port into compliance
mode, and to subsequently bring it out via reset. Historically
according to the (now deprecated) USB 3.0 specification a
SuperSpeed host downstream port would automatically transition
to Compliance mode from the Polling state if LFPS polling times
out. However the language in USB 3.1 as well as xHCI 1.1 states
it may be required to explicitly enable this transition. For
such hosts this is done by sending a SET_FEATURE(PORT_LINK_STATE)
with the state set to Compliance to the root hub port.

Similar to the other supported commands, to do this via sysfs:

     echo  > /sys/bus/usb/devices/2-0\:1.0/enable_compliance

According to xHCI 1.1 section 4.19.1.2.4.1, this enables the
transition to compliance mode upon LFPS timeout. Note that this
can only be issued when the port is in disconnected state. And
in order to disable this behavior on subsequent transitions, a
warm reset should be issued. So add another entry to do that:

     echo  > /sys/bus/usb/devices/2-0\:1.0/warm_reset

In general these attributes can also be useful for other USB
SuperSpeed compliance tests such as electrical and eye diagram
testing which require CPn patterns to be transmitted.

David Lechner 73517cf49b usb: gadget: add RNDIS configfs options for class/subclass/protocol
This adds 3 new options to the RNDIS gadget function configs. It allows
overriding the default USB interface class/subclass/protocol.

The motivation for this is that if you set the values to "ef" (Misc),
"04" (RNDIS), "01" (Ethernet) respectively, then the device will be
recognized by the rndiscmp.inf file in Windows Vista and newer and will
cause Windows to load the correct RNDIS driver without the need for a
custom (signed) .inf file.

Greg Kroah-Hartman 98c2f10d23 First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
 
 One ABI change due to a silly mistake a long time back. Hopefully no
 one will notice.  It effects the numerical order of consumer device
 channels which was the reverse of the obvious.  It's going the slow
 way to allow us some margin to spot if we have broken userspace or
 not (seems unlikely)
 
 New Device Support
 * ccs811
   - new driver for the Volatile Organic Compounds (VOC) sensor.
 * dln2 adc
   - new driver for the ADC on this flexible usb board.
 * EP93xx
   - new driver for this Cirrus logic SoC ADC.
 * ltc2471
   - new ADC driver support the ltc2471 and ltc2473
 * st_accel
   - add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
 * st_gyro
   - add L3GD20H support (again) having fixed the various things that were
     broken in the first try.  Includes devicetree binding.
 * stm32 dac
   - add support for the DACs in the STM32F4 series
 
 Features
 * Documentation
   - add missing power attribute documentation to the ABI docs.
 * at91-sama5d2
   - add hardware trigger and buffered capture support with bindings.
   - suspend and resume functionality.
 * bmc150
   - support for the BOSC0200 ACPI device id seen on some tablets.
 * hdc100x
   - devicetree bindings
   - document supported devices
   - match table and device ids.
 * hts221
   - support active low interrupts (with bindings)
   - open drain mode with bindings.
 * htu21
   - OF match table and bindings.
 * lsm6dsx
   - open drain mode with bindings
 * ltc2497
   - add support for board file based consumer mapping.
 * ms5367
   - OF match table and bindings.
 * mt7622
   - binding document and OF match table.
   - suspend and resume support.
 * rpr0521
   - triggered buffer support.
 * tsys01
   - OF match table and bindings.
 
 Cleanups and minor fixes
 * core
   - fix ordering of IIO channels to entry numbers when using
     iio_map_array_register rather than reversing them.
   - use the new %pOF format specifier rather than full name for the
     device tree nodes.
 * ad7280a
   - fix potential issue with macro argument reuse.
 * ad7766
   - drop a pointless NULL value check as it's done in the gpiod code.
 * adis16400
   - unsigned -> unsigned int.
 * at91 adc
   - make some init data static to reduce code size.
 * at91-sama5d2 ADC
   - make some init data static to reduce code size.
 * da311
   - make some init data static to reduce code size.
 * hid-sensor-rotation
   - drop an unnecessary static.
 * hts221
   - refactor the write_with_mask code.
   - move the BDU configuration to probe time as there is no reason for it
     to change.
   - avoid overwriting reserved data during power-down.  This is a fix, but
     the infrastructure need was too invasive to send it to mainline except
     in a merge window.  It's not a regression as it was always wrong.
   - avoid reconfigure the sampling frequency multiple times by just
     doing it in the write_raw function directly.
   - refactor the power_on/off calls into a set_enable.
   - move the dry-enable logic into trig_set_state as that is the only
     place it was used.

   - add a check of of_match_device return value.
 * mpu3050
   - allow open drain for any interrupt type.
 * rockchip adc
   - add check on of_match_device return value.

 * st_gyro
   - explicit OF table (spi).
 * st_magn
   - explicit OF table (spi).
   - enable multiread for lis3mdl.
 * st_pressure
   - explicit OF table (spi).
 * st_sensors common.
   - move st_sensors_of_i2c_probe and rename to make it available for spi
   drivers.
 * tsc3472
   - don't write an extra byte when writing the ATIME register.
   - add a link to the datasheet.
 * tsl2x7x - continued staging cleanups
   - add of_match_table.
   - drop redundant power_state sysfs attribute.
   - drop wrapper tsl2x7x_i2c_read.

 NAND updates, from Boris Brezillon:
 
  * addition of on-die ECC support to Micron driver
  * addition of helpers to help drivers choose most appropriate ECC
    settings
  * deletion of dead-code (cached programming and ->errstat() hook)
  * make sure drivers that do not support the SET/GET FEATURES command
    return ENOTSUPP use a dummy ->set/get_features implementation

Rafał Miłecki 7d84120b5b Documentation: ABI: mtd: describe "offset" more precisely
So far Linux supported only two levels of MTD devices so we didn't need
a very precise description for this sysfs file. With commit
97519dc52b ("mtd: partitions: add support for subpartitions") there
is support for a tree structure so we should have more precise
description. Using "parent" and "flash device" makes it more accurate.

Chao Yu daeb433e42 f2fs: introduce reserved_blocks in sysfs
In this patch, we add a new sysfs interface, with it, we can control
number of reserved blocks in system which could not be used by user,
it enable f2fs to let user to configure for adjusting over-provision
ratio dynamically instead of changing it by mkfs.

So we can expect it will help to reserve more free space for relieving
GC in both filesystem and flash device.

Linus Torvalds e24dd9ee53 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security layer updates from James Morris:

 - a major update for AppArmor. From JJ:

     * several bug fixes and cleanups

     * the patch to add symlink support to securityfs that was floated
       on the list earlier and the apparmorfs changes that make use of
       securityfs symlinks

     * it introduces the domain labeling base code that Ubuntu has been
       carrying for several years, with several cleanups applied. And it
       converts the current mediation over to using the domain labeling
       base, which brings domain stacking support with it. This finally
       will bring the base upstream code in line with Ubuntu and provide
       a base to upstream the new feature work that Ubuntu carries.

     * This does _not_ contain any of the newer apparmor mediation
       features/controls (mount, signals, network, keys, ...) that
       Ubuntu is currently carrying, all of which will be RFC'd on top
       of this.

 - Notable also is the Infiniband work in SELinux, and the new file:map
   permission. From Paul:

      "While we're down to 21 patches for v4.13 (it was 31 for v4.12),
       the diffstat jumps up tremendously with over 2k of line changes.

       Almost all of these changes are the SELinux/IB work done by
       Daniel Jurgens; some other noteworthy changes include a NFS v4.2
       labeling fix, a new file:map permission, and reporting of policy
       capabilities on policy load"

   There's also now genfscon labeling support for tracefs, which was
   lost in v4.1 with the separation from debugfs.

 - Smack incorporates a safer socket check in file_receive, and adds a
   cap_capable call in privilege check.

 - TPM as usual has a bunch of fixes and enhancements.

 - Multiple calls to security_add_hooks() can now be made for the same
   LSM, to allow LSMs to have hook declarations across multiple files.

 - IMA now supports different "ima_appraise=" modes (eg. log, fix) from
   the boot command line.

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (126 commits)

Pull staging/IIO updates from Greg KH:
 "Here's the large set of staging and iio driver patches for 4.13-rc1.

  After over 500 patches, we removed about 200 more lines of code than
  we added, not great, but we added some new IIO drivers for unsupported
  hardware, so it's an overall win.

  Also here are lots of small fixes, and some tty core api additions
  (with the tty maintainer's ack) for the speakup drivers, those are
  finally getting some much needed cleanups and are looking much better
  now than before. Full details in the shortlog.

  All of these have been in linux-next for a while with no reported

Ruslan Bilovol 0591bc2360 usb: gadget: add f_uac1 variant based on a new u_audio api
This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.

Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card

f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.

f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.

f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.

Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.

Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.

g_audio can be built using one of existing
UAC functions (f_uac1, f_uac1_legacy or f_uac2)

Mika Westerberg e6b245ccd5 thunderbolt: Add support for host and device NVM firmware upgrade
Starting from Intel Falcon Ridge the NVM firmware can be upgraded by
using DMA configuration based mailbox commands. If we detect that the
host or device (device support starts from Intel Alpine Ridge) has the
DMA configuration based mailbox we expose NVM information to the
userspace as two separate Linux NVMem devices: nvm_active and
nvm_non_active. The former is read-only portion of the active NVM which
firmware upgrade tools can be use to find out suitable NVM image if the
device identification strings are not enough.

The latter is write-only portion where the new NVM image is to be
written by the userspace. It is up to the userspace to find out right
NVM image (the kernel does very minimal validation). The ICM firmware
itself authenticates the new NVM firmware and fails the operation if it
is not what is expected.

We also expose two new sysfs files per each switch: nvm_version and
nvm_authenticate which can be used to read the active NVM version and
start the upgrade process.

We also introduce safe mode which is the mode a switch goes when it does
not have properly authenticated firmware. In this mode the switch only
accepts a couple of commands including flashing a new NVM firmware image
and triggering power cycle.

This code is based on the work done by Amir Levy and Michael Jamet.

Mika Westerberg f67cf49117 thunderbolt: Add support for Internal Connection Manager (ICM)
Starting from Intel Falcon Ridge the internal connection manager running
on the Thunderbolt host controller has been supporting 4 security
levels. One reason for this is to prevent DMA attacks and only allow
connecting devices the user trusts.

The internal connection manager (ICM) is the preferred way of connecting
Thunderbolt devices over software only implementation typically used on
Macs. The driver communicates with ICM using special Thunderbolt ring 0
(control channel) messages. In order to handle these messages we add
support for the ICM messages to the control channel.

The security levels are as follows:

  none - No security, all tunnels are created automatically
  user - User needs to approve the device before tunnels are created
  secure - User need to approve the device before tunnels are created.
	   The device is sent a challenge on future connects to be able
	   to verify it is actually the approved device.
  dponly - Only Display Port and USB tunnels can be created and those
           are created automatically.

The security levels are typically configurable from the system BIOS and
by default it is set to "user" on many systems.

In this patch each Thunderbolt device will have either one or two new
sysfs attributes: authorized and key. The latter appears for devices
that support secure connect.

In order to identify the device the user can read identication
information, including UUID and name of the device from sysfs and based
on that make a decision to authorize the device. The device is
authorized by simply writing 1 to the "authorized" sysfs attribute. This
is following the USB bus device authorization mechanism. The secure
connect requires an additional challenge step (writing 2 to the
"authorized" attribute) in future connects when the key has already been
stored to the NVM of the device.

Non-ICM systems (before Alpine Ridge) continue to use the existing
functionality and the security level is set to none. For systems with
Alpine Ridge, even on Apple hardware, we will use ICM.

This code is based on the work done by Amir Levy and Michael Jamet.

Mika Westerberg bfe778ac49 thunderbolt: Convert switch to a device
Thunderbolt domain consists of switches that are connected to each
other, forming a bus. This will convert each switch into a real Linux
device structure and adds them to the domain. The advantage here is
that we get all the goodies from the driver core, like reference
counting and sysfs hierarchy for free.

Also expose device identification information to the userspace via new
sysfs attributes.

In order to support internal connection manager (ICM) we separate switch
configuration into its own function (tb_switch_configure()) which is
only called by the existing native connection manager implementation
used on Macs.

10GBASE-KR is a single lane Serdes backplane ethernet connection method
with autonegotiation on the link.  Some PHYs use this to connect to the
ethernet interface at 10G speeds, switching to other connection types
when utilising slower speeds.

10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber

Peter Rosin a3b02a9c65 mux: minimal mux subsystem
Add a new minimalistic subsystem that handles multiplexer controllers.
When multiplexers are used in various places in the kernel, and the
same multiplexer controller can be used for several independent things,
there should be one place to implement support for said multiplexer
controller.

A single multiplexer controller can also be used to control several
parallel multiplexers, that are in turn used by different subsystems
in the kernel, leading to a need to coordinate multiplexer accesses.
The multiplexer subsystem handles this coordination.

  - trivial support for bma250e (new id)
* hid-sensor-rotation
  - add relative orientation and geometric orientation support.
* isl29028
  - add isl29030 support (its effectively the same part from a driver point of
  view)

  value doesn't appear to be raw (error path).
  - fixup accidental sizeof pointer in iio_device_add_mask_type.
* docs
  - fix an accidental duplicated line in sysfs-bus-iio-meas-spec.

  - use local include/uapi headers to ensure always up to date.
  - increase length of allowed trigger names.
* ad9834
  - symbolic to octal permissions.
* ade7753
  - symbolic to octal permissions.
  - fix indentation
* ade7754
  - symbolic to octal permissions.
* ade7758
  - symbolic to octal permissions.
- ade7854
  - symbolic to octal permissions.
* as3935
  - move out of storm check to given consistent results for raw and processed
  values.
* bmp280
  - fix bme280 naming in Kconfig help.
* hi8435
  - avoid garbage on event after enable.
  - add missing in_voltage_sensing_mode_available to list possible enum options.
  - handle the reset gpio with the obvious polarity rather than relying on
  DT to provide it correctly.
* hid-sensors
  - fix a wrong error path scrubbing of return values.
* hid-sensors-accel
  - drop static on a local variable
* hid-sensors-rotation
  - Add missing scale and offset property parsing support.
* ina2xx
  - Fix a bad use of GENMASK and some typos and whitespace issues.
* isl29018
  - only declare the ACPI table when ACPI is enabled.
* isl29028
  - fix proximity sleep times.
* lsm6dsx
  - replace ifdef CONFIG_PM with __maybe_unused to avoid the complexity of
  dealing with the various PM config variables.
* meson-saradc
  - mark meson_sar_adc_data static and const.
* rcar-gyroadc
  - derive the interface clock speed from the fck clock on the basis they are
  the same actual clock.
  - drop the now unused if clock from the bindings.
* rpr0521
  - disable sensor when marked as such rather than always enabling it.
  - poweroff if probe fails and we can talk to device.
  - make sure device powered off when it doesn't need to be on.
  - use sizeof rather than hardcoded size on value read.
  - whitespace fixup.
  - reorder channel numbers ready for buffered support which didn't quite
  make this pull request.
* st-accel
  - fix platform data initialization to allow remove and reprobe.
* st-pressure
  - fix platform data initialization to allow remove and reprobe.
* tsl2x7x
  - S_IRUGO, S_IWUSR to octal values
  - rename driver for consistency with more recent drivers
  - drop FSF mailing address
  - replace DEVICE_ATTR macros with the shorter DEVICE_ATTR_RW form and
  relevant function renames.
* zpa2326
  - report an error for consistency with other error paths.

Peter Rajnoha f36776fafb kobject: support passing in variables for synthetic uevents
This patch makes it possible to pass additional arguments in addition
to uevent action name when writing /sys/.../uevent attribute. These
additional arguments are then inserted into generated synthetic uevent
as additional environment variables.

Before, we were not able to pass any additional uevent environment
variables for synthetic uevents. This made it hard to identify such uevents
properly in userspace to make proper distinction between genuine uevents
originating from kernel and synthetic uevents triggered from userspace.
Also, it was not possible to pass any additional information which would
make it possible to optimize and change the way the synthetic uevents are
processed back in userspace based on the originating environment of the
triggering action in userspace. With the extra additional variables, we are
able to pass through this extra information needed and also it makes it
possible to synchronize with such synthetic uevents as they can be clearly
identified back in userspace.

The format for writing the uevent attribute is following:

    ACTION [UUID [KEY=VALUE ...]

There's no change in how "ACTION" is recognized - it stays the same
("add", "change", "remove"). The "ACTION" is the only argument required
to generate synthetic uevent, the rest of arguments, that this patch
adds support for, are optional.

The "UUID" is considered as transaction identifier so it's possible to
use the same UUID value for one or more synthetic uevents in which case
we logically group these uevents together for any userspace listeners.
The "UUID" is expected to be in "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
format where "x" is a hex digit. The value appears in uevent as
"SYNTH_UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" environment variable.

The "KEY=VALUE" pairs can contain alphanumeric characters only. It's
possible to define zero or more more pairs - each pair is then delimited
by a space character " ". Each pair appears in synthetic uevents as
"SYNTH_ARG_KEY=VALUE" environment variable. That means the KEY name gains
"SYNTH_ARG_" prefix to avoid possible collisions with existing variables.
To pass the "KEY=VALUE" pairs, it's also required to pass in the "UUID"
part for the synthetic uevent first.

If "UUID" is not passed in, the generated synthetic uevent gains
"SYNTH_UUID=0" environment variable automatically so it's possible to
identify this situation in userspace when reading generated uevent and so
we can still make a difference between genuine and synthetic uevents.
