      HID: wacom: Queue events with missing type/serial data for later processing · 83417206
      Jason Gerecke authored
      Userspace expects to receive tool type and serial number information
      for the active pen in the very first kernel report, if such data is
      supported by the hardware. While this expectation is not an issue for
      EMR devices, AES sensors will often send several packets worth of in-
      range data before relaying type/serial data to the kernel. Sending this
      data "late" can result in proximity-tracking issues by xf86-input-wacom,
      or an inability to distinguish different pens by input-wacom.
      
      Options for dealing with this situation include ignoring reports from
      the tablet until we get the necessary data, or using the information
      from the last-seen pen instead of the (eventual) real data. Neither
      option is particularly attractive: the former results in truncated
      strokes and the latter causes issues with switching between pens.
      
      This commit instead opts to queue up events with missing information
      until we receive a report which contains it. At that point, we can
      update the driver's state variables (id[0] and serial[0]) and replay
      the queued events.

      HID: wacom: Properly handle AES serial number and tool type · 99acedad
      Jason Gerecke authored
      Current AES sensors relay tool type and serial number information with
      a different set of usages than those prescribed by the modern (i.e.
      MobileStudio Pro and newer) EMR tablet standard. To ensure the driver
      properly understands these usages, we modify them to be compatible.
      The identifying information is split across three consecutive fields:
      a 16-bit WACOM_HID_WT_SERIALNUMBER (which is more accurately described
      as WACOM_HID_WD_TOOLTYPE), a 32-bit HID_DG_TOOLSERIALNUMBER, and an
      8-bit 0xFF000000 (which should be WACOM_HID_WD_SERIALHI). While we're
      at it, we also define proper min/max values since may may be undefined
      on some devices.

       "There are no big surprising changes in this cycle, yet not too boring,
        either. The biggest change from diffstat POV is the removal of the
        legacy OSS driver codes that have been already disabled for a long
        time. This will bring a few trivial merge conflicts.
      
        As new features in ASoC side, there are two things: a new AC97 bus
        implementation and AMD Stony platform support. Both include the
        relevant changes shared with other subsystems, e.g. AC97 MFD changes
        and DRM AMD changes.
      
        Some other highlighted topics are:
      
         - A bunch of USB-audio drivers got the hardening against the
           malicious device accesses with a new helper code for endpoint
           sanity check
      
         - Lots of cleanups for ASoC Intel platform code, including support
           for their open source audio firmware
      
         - Continued ASoC core componentization works
      
         - Support for scaling MCLK with sample rate in ASoC simple-card

        they have been for a while. They are namely:
      
         - to-gpiod conversion of the i2c-gpio driver and its users (touching
           arch/* and drivers/mfd/*)
      
         - adding a sbs-manager based on I2C core updates to SMBus alerts
           (touching drivers/power/*)
      
        Other notable changes:
      
         - i2c_boardinfo can now carry a dev_name to be used when the device
           is created. This is because some devices in ACPI world need fixed
           names to find the regulators.
      
         - the designware driver got a long discussed overhaul of its PM
           handling. img-scb and davinci got PM support, too.
      
         - at24 driver has way better OF support. And it has a new maintainer.

           hammer.
      
         - Rewrote the __inner_function() notation calls to names that make
           more sense. I just find this kind of code disturbing.
      
         - Drop the .irq_base() field from the gpiochip since now all IRQs are
           mapped dynamically. This is nice.
      
         - Support for .get_multiple() in the core driver API. This allows us
           to read several GPIO lines with a single register read. This has
           high value for some usecases: it can be used to create
           oscilloscopes and signal analyzers and other things that rely on
           reading several lines at exactly the same instant. Also a generally
           nice optimization. This uses the new assign_bit() macro from the
           bitops lib that was ACKed by Andrew Morton and is implemented for
           two drivers, one of them being the generic MMIO driver so everyone
           using that will be able to benefit from this.
      
         - Do not allow requests of Open Drain and Open Source setting of a
           GPIO line simultaneously. If the hardware actually supports
           enabling both at the same time the electrical result would be
           disastrous.
      
         - A new interrupt chip core helper. This will be helpful to deal with
           "banked" GPIOs, which means GPIO controllers with several logical
           blocks of GPIO inside them. This is several gpiochips per device in
           the device model, in contrast to the case when there is a 1-to-1
           relationship between a device and a gpiochip.
      
        New drivers:
      
         - Maxim MAX3191x industrial serializer, a very interesting piece of
           professional I/O hardware.
      
         - Uniphier GPIO driver. This is the GPIO block from the recent
           Socionext (ex Fujitsu and Panasonic) platform.
      
         - Tegra 186 driver. This is based on the new banked GPIO
           infrastructure.
      
        Other improvements:
      
         - Some documentation improvements.
      
         - Wakeup support for the DesignWare DWAPB GPIO controller.
      
         - Reset line support on the DesignWare DWAPB GPIO controller.
      
         - Several non-critical bug fixes and improvements for the Broadcom
           BRCMSTB driver.
      
         - Misc non-critical bug fixes like exotic errorpaths, removal of dead
           code etc.
      
         - Explicit comments on fall-through switch() statements"

       "This is the main pull request for block storage for 4.15-rc1.
      
        Nothing out of the ordinary in here, and no API changes or anything
        like that. Just various new features for drivers, core changes, etc.
        In particular, this pull request contains:
      
         - A patch series from Bart, closing the whole on blk/scsi-mq queue
           quescing.
      
         - A series from Christoph, building towards hidden gendisks (for
           multipath) and ability to move bio chains around.
      
         - NVMe
              - Support for native multipath for NVMe (Christoph).
              - Userspace notifications for AENs (Keith).
              - Command side-effects support (Keith).
              - SGL support (Chaitanya Kulkarni)
              - FC fixes and improvements (James Smart)
              - Lots of fixes and tweaks (Various)
      
         - bcache
              - New maintainer (Michael Lyle)
              - Writeback control improvements (Michael)
              - Various fixes (Coly, Elena, Eric, Liang, et al)
      
         - lightnvm updates, mostly centered around the pblk interface
           (Javier, Hans, and Rakesh).
      
         - Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)
      
         - Writeback series that fix the much discussed hundreds of millions
           of sync-all units. This goes all the way, as discussed previously
           (me).
      
         - Fix for missing wakeup on writeback timer adjustments (Yafang
           Shao).
      
         - Fix laptop mode on blk-mq (me).
      
         - {mq,name} tupple lookup for IO schedulers, allowing us to have
           alias names. This means you can use 'deadline' on both !mq and on
           mq (where it's called mq-deadline). (me).

      Linus Torvalds authored
      Pull gfs2 updates from Bob Peterson:
       "We've got a total of 17 GFS2 patches for this merge window. The
        patches are basically in three categories: (1) patches related to
        broken xfstest cases, (2) patches related to improving iomap and start
        using it in GFS2, and (3) general typos and clarifications.
      
        Please note that one of the iomap patches extends beyond GFS2 and
        affects other file systems, but it was publically reviewed by a
        variety of file system people in the community.
      
        From Andreas Gruenbacher:
      
         - rename variable 'bsize' to 'factor' to clarify the logic related to
           gfs2_block_map.
      
         - correctly set ctime in the setflags ioctl, which fixes broken
           xfstests test 277.
      
         - fix broken xfstest 258, due to an atime initialization problem.
      
         - fix broken xfstest 307, in which GFS2 was not setting ctime when
           setting acls.
      
         - switch general iomap code from blkno to disk offset for a variety
           of file systems.
      
         - add a new IOMAP_F_DATA_INLINE flag for iomap to indicate blocks
           that have data mixed with metadata.
      
         - implement SEEK_HOLE and SEEK_DATA via iomap in GFS2.
      
         - fix failing xfstest case 066, which was due to not properly syncing
           dirty inodes when changing extended attributes.
      
         - fix a minor typo in a comment.
      
         - partially fix xfstest 424, which involved GET_FLAGS and SET_FLAGS
           ioctl. This is also a cleanup and simplification of the translation
           of flags from fs flags to gfs2 flags.
      
         - add support for STATX_ATTR_ in statx, which fixed broken xfstest
           424.
      
         - fix for failing xfstest 093 which fixes a recursive glock problem
           with gfs2_xattr_get and _set
      
        From me:
      
         - make inode height info part of the 'metapath' data structure to
           facilitate using iomap in GFS2.
      
         - start using iomap inside GFS2 and switch GFS2's block_map functions
           to use iomap under the covers.
      
         - switch GFS2's fiemap implementation from using block_map to using
           iomap under the covers.
      
         - fix journaled data pages not being properly synced to media when
           writing inodes. This was caught with xfstests.
      
         - fix another failing xfstest case in which switching a file from
           ordered_write to journaled data via set_flags caused a deadlock"

           postprocessing in userspace, aiding defragmentation or
           deduplication tools
      
         - populate compression heuristics logic, do data sampling and try to
           guess compressibility by: looking for repeated patterns, counting
           unique byte values and distribution, calculating Shannon entropy;
           this will need more benchmarking and possibly fine tuning, but the
           base should be good enough
      
         - enable indexing for btrfs as lower filesystem in overlayfs
      
         - speedup page cache readahead during send on large files
      
        Internal enhancements:
      
         - more sanity checks of b-tree items when reading them from disk
      
         - more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other

         - remove some homegrown IO-related logic, that's been obsoleted by
           core block layer changes (batching, plug/unplug, own counters)

      Linus Torvalds authored
      Pull xfs updates from Darrick Wong:
       "xfs: great scads of new stuff for 4.15.
      
        This merge cycle, we're making some substantive changes to XFS. The
        in-core extent mappings have been refactored to use proper iterators
        and a btree to handle heavily fragmented files without needing
        high-order memory allocations; some important log recovery bug fixes;
        and the first part of the online fsck functionality.
      
        (The online fsck feature is disabled by default and more pieces of it
        will be coming in future release cycles.)
      
        This giant pile of patches has been run through a full xfstests run
        over the weekend and through a quick xfstests run against this
        morning's master, with no major failures reported.
      
        New in this version:
      
         - Refactor the incore extent map manipulations to use a cursor
           instead of directly modifying extent data.
      
         - Refactor the incore extent map cursor to use an in-memory btree
           instead of a single high-order allocation. This eliminates a major
           source of complaints about insufficient memory when opening a
           heavily fragmented file into a system whose memory is also heavily
           fragmented.
      
         - Fix a longstanding bug where deleting a file with a complex
           extended attribute btree incorrectly handled memory pointers, which
           could lead to memory corruption.
      
         - Improve metadata validation to eliminate crashing problems found
           while fuzzing xfs.
      
         - Move the error injection tag definitions into libxfs to be shared
           with userspace components.
      
         - Fix some log recovery bugs where we'd underflow log block position
           vector and incorrectly fail log recovery.
      
         - Drain the buffer lru after log recovery to force recovered buffers
           back through the verifiers after mount. On a v4 filesystem the log
           never attaches verifiers during log replay (v5 does), so we could
           end up with buffers marked verified but without having ever been
           verified.
      
         - Fix various other bugs.
      
         - Introduce the first part of a new online fsck tool. The new fsck
           tool will be able to iterate every piece of metadata in the
           filesystem to look for obvious errors and corruptions. In the next
           release cycle the checking will be extended to cross-reference with
           the other fs metadata, so this feature should only be used by the
           developers in the mean time"

      Pull USB/PHY updates from Greg KH:
       "Here is the big set of USB and PHY driver updates for 4.15-rc1.
      
        There is the usual amount of gadget and xhci driver updates, along
        with phy and chipidea enhancements. There's also a lot of SPDX tags
        and license boilerplate cleanups as well, which provide some churn in
        the diffstat.
      
        Other major thing is the typec code that moved out of staging and into
        the "real" part of the drivers/usb/ tree, which was nice to see
        happen.
      
        All of these have been in linux-next with no reported issues for a
        while"
