      HID: i2c-hid: goodix: Fix a lockdep splat · 2787710f
      Daniel Thompson authored
      
      
      I'm was on the receiving end of a lockdep splat from this driver and after
      scratching my head I couldn't be entirely sure it was a false positive
      given we would also have to think about whether the regulator locking is
      safe (since the notifier is called whilst holding regulator locks which
      are also needed for regulator_is_enabled() ).
      
      Regardless of whether it is a real bug or not, the mutex isn't needed.
      We can use reference counting tricks instead to avoid races with the
      notifier calls.
      
      The observed splat follows:
      
      ------------------------------------------------------
      kworker/u16:3/127 is trying to acquire lock:
      ffff00008021fb20 (&ihid_goodix->regulator_mutex){+.+.}-{4:4}, at: ihid_goodix_vdd_notify+0x30/0x94
      
      but task is already holding lock:
      ffff0000835c60c0 (&(&rdev->notifier)->rwsem){++++}-{4:4}, at: blocking_notifier_call_chain+0x30/0x70

      HID: apple: Set the tilde quirk flag on the Wellspring 5 and later · e26a7805
      Alex Henrie authored
      
      
      Markus reports that his 2011 MacBook with a German ISO keyboard (USB
      product code 05ac:0246, HID country code 13) has the tilde key quirk.
      Seeing as all of the standalone Apple ISO keyboards since about 2008
      have the quirk, it seems reasonable to assume that once the integrated
      laptop keyboards started having the quirk, they likewise never stopped
      having it.

      HID: wacom: Avoid using stale array indicies to read contact count · 20f3cf5f
      Jason Gerecke authored
      If we ever see a touch report with contact count data we initialize
      several variables used to read the contact count in the pre-report
      phase. These variables are never reset if we process a report which
      doesn't contain a contact count, however. This can cause the pre-
      report function to trigger a read of arbitrary memory (e.g. NULL
      if we're lucky) and potentially crash the driver.
      
      This commit restores resetting of the variables back to default
      "none" values that were used prior to the commit mentioned
      below.

      HID: wacom: Ignore the confidence flag when a touch is removed · df03e9bd
      Jason Gerecke authored
      AES hardware may internally re-classify a contact that it thought was
      intentional as a palm. Intentional contacts are reported as "down" with
      the confidence bit set. When this re-classification occurs, however, the
      state transitions to "up" with the confidence bit cleared. This kind of
      transition appears to be legal according to Microsoft docs, but we do
      not handle it correctly. Because the confidence bit is clear, we don't
      call `wacom_wac_finger_slot` and update userspace. This causes hung
      touches that confuse userspace and interfere with pen arbitration.
      
      This commit adds a special case to ignore the confidence flag if a contact
      is reported as removed. This ensures we do not leave a hung touch if one
      of these re-classification events occured. Ideally we'd have some way to
      also let userspace know that the touch has been re-classified as a palm
      and needs to be canceled, but that's not possible right now :)

      HID: wacom: Reset expected and received contact counts at the same time · 546e41ac
      Jason Gerecke authored
      These two values go hand-in-hand and must be valid for the driver to
      behave correctly. We are currently lazy about updating the values and
      rely on the "expected" code flow to take care of making sure they're
      valid at the point they're needed. The "expected" flow changed somewhat
      with commit f8b6a747 ("HID: wacom: generic: Support multiple tools
      per report"), however. This led to problems with the DTH-2452 due (in
      part) to *all* contacts being fully processed -- even those past the
      expected contact count. Specifically, the received count gets reset to
      0 once all expected fingers are processed, but not the expected count.
      The rest of the contacts in the report are then *also* processed since
      now the driver thinks we've only processed 0 of N expected contacts.
      
      Later commits such as 7fb0413b (HID: wacom: Use "Confidence" flag to
      prevent reporting invalid contacts) worked around the DTH-2452 issue by
      skipping the invalid contacts at the end of the report, but this is not
      a complete fix. The confidence flag cannot be relied on when a contact
      is removed (see the following patch), and dealing with that condition
      re-introduces the DTH-2452 issue unless we also address this contact
      count laziness. By resetting expected and received counts at the same
      time we ensure the driver understands that there are 0 more contacts
      expected in the report. Similarly, we also make sure to reset the
      received count if for some reason we're out of sync in the pre-report
      phase.

      HID: uhid: Fix worker destroying device without any protection · 4ea5763f
      Jann Horn authored
      uhid has to run hid_add_device() from workqueue context while allowing
      parallel use of the userspace API (which is protected with ->devlock).
      But hid_add_device() can fail. Currently, that is handled by immediately
      destroying the associated HID device, without using ->devlock - but if
      there are concurrent requests from userspace, that's wrong and leads to
      NULL dereferences and/or memory corruption (via use-after-free).
      
      Fix it by leaving the HID device as-is in the worker. We can clean it up
      later, either in the UHID_DESTROY command handler or in the ->release()
      handler.

      Unfortunately details of USB HID transport bled into HID core and

      Battery status on Elan tablet driver is reported for the HP ENVY x360

      Pull workqueue updates from Tejun Heo:
      
       - The code around workqueue scheduler hooks got reorganized early 2019
         which unfortuately introdued a couple subtle and rare race conditions
         where preemption can mangle internal workqueue state triggering a
         WARN and possibly causing a stall or at least delay in execution.
      
         Frederic fixed both early December and the fixes were sitting in
         for-5.16-fixes which I forgot to push. They are here now. I'll
         forward them to stable after they land.
      
       - The scheduler hook reorganization has more implicatoins for workqueue
         code in that the hooks are now more strictly synchronized and thus
         the interacting operations can become more straight-forward.
      
         Lai is in the process of simplifying workqueue code and this pull

      select: Fix indefinitely sleeping task in poll_schedule_timeout() · 68514dac
      Jan Kara authored
      
      
      A task can end up indefinitely sleeping in do_select() ->
      poll_schedule_timeout() when the following race happens:
      
        TASK1 (thread1)             TASK2                   TASK1 (thread2)
        do_select()
          setup poll_wqueues table
          with 'fd'
                                    write data to 'fd'
                                      pollwake()
                                        table->triggered = 1
                                                            closes 'fd' thread1 is
                                                              waiting for
          poll_schedule_timeout()
            - sees table->triggered
            table->triggered = 0
            return -EINTR
          loop back in do_select()
      
      But at this point when TASK1 loops back, the fdget() in the setup of
      poll_wqueues fails.  So now so we never find 'fd' is ready for reading
      and sleep in poll_schedule_timeout() indefinitely.
      
      Treat an fd that got closed as a fd on which some event happened.  This
      makes sure cannot block indefinitely in do_select().
      
      Another option would be to return -EBADF in this case but that has a
      potential of subtly breaking applications that excercise this behavior
      and it happens to work for them.  So returning fd as active seems like a
      safer choice.

      Pull power management updates from Rafael Wysocki:
       "The most signigicant change here is the addition of a new cpufreq
        'P-state' driver for AMD processors as a better replacement for the
        venerable acpi-cpufreq driver.
      
        There are also other cpufreq updates (in the core, intel_pstate, ARM
        drivers), PM core updates (mostly related to adding new macros for
        declaring PM operations which should make the lives of driver
        developers somewhat easier), and a bunch of assorted fixes and
        cleanups.
      
        Summary:
      
         - Add new P-state driver for AMD processors (Huang Rui).
      
         - Fix initialization of min and max frequency QoS requests in the
           cpufreq core (Rafael Wysocki).
      
         - Fix EPP handling on Alder Lake in intel_pstate (Srinivas
           Pandruvada).
      
         - Make intel_pstate update cpuinfo.max_freq when notified of HWP
           capabilities changes and drop a redundant function call from that
           driver (Rafael Wysocki).
      
         - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
           Stephen Boyd, Vladimir Zapolskiy).
      
         - Fix double devm_remap() in the Mediatek cpufreq driver (Hector
           Yuan).
      
         - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz
           Luba).
      
         - Make cpufreq use default_groups in kobj_type (Greg Kroah-Hartman).
      
         - Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).
      
         - Fix two comments in cpuidle code (Jason Wang, Yang Li).
      
         - Allow model-specific normal EPB value to be used in the intel_epb
           sysfs attribute handling code (Srinivas Pandruvada).
      
         - Simplify locking in pm_runtime_put_suppliers() (Rafael Wysocki).
      
         - Add safety net to supplier device release in the runtime PM core
           code (Rafael Wysocki).
      
         - Capture device status before disabling runtime PM for it (Rafael
           Wysocki).
      
         - Add new macros for declaring PM operations to allow drivers to
           avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
           update some drivers to use these macros (Paul Cercueil).
      
         - Allow ACPI hardware signature to be honoured during restore from
           hibernation (David Woodhouse).
      
         - Update outdated operating performance points (OPP) documentation
           (Tang Yizhou).
      
         - Reduce log severity for informative message regarding frequency
           transition failures in devfreq (Tzung-Bi Shih).
      
         - Add DRAM frequency controller devfreq driver for Allwinner sunXi
           SoCs (Samuel Holland).
      
         - Add missing COMMON_CLK dependency to sun8i devfreq driver (Arnd
           Bergmann).
      
         - Add support for new layout of Psys PowerLimit Register on SPR to
           the Intel RAPL power capping driver (Zhang Rui).
      
         - Fix typo in a comment in idle_inject.c (Jason Wang).
      
         - Remove unused function definition from the DTPM (Dynamit Thermal
           Power Management) power capping framework (Daniel Lezcano).
      
         - Reduce DTPM trace verbosity (Daniel Lezcano)"

      netfilter: nf_tables: don't use 'data_size' uninitialized · 63045bfd
      Linus Torvalds authored
      Commit 2c865a8a ("netfilter: nf_tables: add rule blob layout") never
      initialized the new 'data_size' variable.
      
      I'm not sure how it ever worked, but it might have worked almost by
      accident - gcc seems to occasionally miss these kinds of 'variable used
      uninitialized' situations, but I've seen it do so because it ended up
      zero-initializing them due to some other simplification.
      
      But clang is very unhappy about it all, and correctly reports
      
          net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized]
                                  data_size += sizeof(*prule) + rule->dlen;
                                  ^~~~~~~~~
          net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning
                  unsigned int size, data_size;
                                              ^
                                               = 0
          1 error generated.
      
      and this fix just initializes 'data_size' to zero before the loop.

       "Core
        ----
      
         - Defer freeing TCP skbs to the BH handler, whenever possible, or at
           least perform the freeing outside of the socket lock section to
           decrease cross-CPU allocator work and improve latency.
      
         - Add netdevice refcount tracking to locate sources of netdevice and
           net namespace refcount leaks.
      
         - Make Tx watchdog less intrusive - avoid pausing Tx and restarting
           all queues from a single CPU removing latency spikes.
      
         - Various small optimizations throughout the stack from Eric Dumazet.
      
         - Make netdev->dev_addr[] constant, force modifications to go via
           appropriate helpers to allow us to keep addresses in ordered data
           structures.
      
         - Replace unix_table_lock with per-hash locks, improving performance
           of bind() calls.
      
         - Extend skb drop tracepoint with a drop reason.
      
         - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
      
        BPF
        ---
      
         - New helpers:
            - bpf_find_vma(), find and inspect VMAs for profiling use cases
            - bpf_loop(), runtime-bounded loop helper trading some execution
              time for much faster (if at all converging) verification
            - bpf_strncmp(), improve performance, avoid compiler flakiness
            - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
              for tracing programs, all inlined by the verifier
      
         - Support BPF relocations (CO-RE) in the kernel loader.
      
         - Further the support for BTF_TYPE_TAG annotations.
      
         - Allow access to local storage in sleepable helpers.
      
         - Convert verifier argument types to a composable form with different
           attributes which can be shared across types (ro, maybe-null).
      
         - Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
           creating new, extensible ones where missing and deprecating those
           to be removed.
      
        Protocols
        ---------
      
         - WiFi (mac80211/cfg80211):
            - notify user space about long "come back in N" AP responses,

            - allow non-standard VHT MCS 10/11 rates
            - use coarse time in airtime fairness code to save CPU cycles
      
         - Bluetooth:
            - rework of HCI command execution serialization to use a common
              queue and work struct, and improve handling errors reported in
              the middle of a batch of commands
            - rework HCI event handling to use skb_pull_data, avoiding packet
              parsing pitfalls
            - support AOSP Bluetooth Quality Report
      
         - SMC:
            - support net namespaces, following the RDMA model
            - improve connection establishment latency by pre-clearing buffers

            - support cmsgs: TCP_INQ
            - improvements in the data scheduler (assigning data to subflows)
            - support fastclose option (quick shutdown of the full MPTCP
              connection, similar to TCP RST in regular TCP)
      
         - MCTP (Management Component Transport) over serial, as defined by
           DMTF spec DSP0253 - "MCTP Serial Transport Binding".
      
        Driver API
        ----------
      
         - Support timestamping on bond interfaces in active/passive mode.
      
         - Introduce generic phylink link mode validation for drivers which
           don't have any quirks and where MAC capability bits fully express
           what's supported. Allow PCS layer to participate in the validation.
           Convert a number of drivers.
      
         - Add support to set/get size of buffers on the Rx rings and size of
           the tx copybreak buffer via ethtool.
      
         - Support offloading TC actions as first-class citizens rather than
           only as attributes of filters, improve sharing and device resource
           utilization.
      
         - WiFi (mac80211/cfg80211):
            - support forwarding offload (ndo_fill_forward_path)

         - tsnep - FPGA based TSN endpoint Ethernet MAC used in PLCs with
           real-time requirements for isochronous communication with protocols
           like OPC UA Pub/Sub.
      
         - Qualcomm BAM-DMUX WWAN - driver for data channels of modems
           integrated into many older Qualcomm SoCs, e.g. MSM8916 or MSM8974

      Pull slab updates from Vlastimil Babka:
      
       - Separate struct slab from struct page - an offshot of the page folio
         work.
      
         Struct page fields used by slab allocators are moved from struct page
         to a new struct slab, that uses the same physical storage. Similar to
         struct folio, it always is a head page. This brings better type
         safety, separation of large kmalloc allocations from true slabs, and
         cleanup of related objcg code.
      
       - A SLAB_MERGE_DEFAULT config optimization.

      Pull random number generator updates from Jason Donenfeld:
       "These a bit more numerous than usual for the RNG, due to folks
        resubmitting patches that had been pending prior and generally renewed
        interest.
      
        There are a few categories of patches in here:
      
         1) Dominik Brodowski and I traded a series back and forth for a some
            weeks that fixed numerous issues related to seeds being provided
            at extremely early boot by the firmware, before other parts of the
            kernel or of the RNG have been initialized, both fixing some
            crashes and addressing correctness around early boot randomness.
            One of these is marked for stable.
      
         2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
            extractor, and made the construction a bit safer and more
            standard. This was sort of a long overdue low hanging fruit, as we
            were supposed to have phased out SHA-1 usage quite some time ago
            (even if all we needed here was non-invertibility). Along the way
            it also made extraction 131% faster. This required a bit of
            Kconfig and symbol plumbing to make things work well with the
            crypto libraries, which is one of the reasons why I'm sending you
            this pull early in the cycle.
      
         3) I got rid of a truly superfluous call to RDRAND in the hot path,
            which resulted in a whopping 370% increase in performance.
      
         4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
            the full series of which wasn't ready yet, but the first two
            preparatory cleanups were good on their own. One of them touches
            files in kernel/irq/, which is the other reason why I'm sending
            you this pull early in the cycle.
      
         5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
            Mark Brown, Dominik Brodowski, and myself"
