      Merge tag 'trace-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace · 95f1fa9e
      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
       "New tracing features:
      
         - New PERMANENT flag to ftrace_ops when attaching a callback to a
           function.
      
           As /proc/sys/kernel/ftrace_enabled when set to zero will disable
           all attached callbacks in ftrace, this has a detrimental impact on
           live kernel tracing, as it disables all that it patched. If a
           ftrace_ops is registered to ftrace with the PERMANENT flag set, it
           will prevent ftrace_enabled from being disabled, and if
           ftrace_enabled is already disabled, it will prevent a ftrace_ops
           with PREMANENT flag set from being registered.
      
         - New register_ftrace_direct().
      
           As eBPF would like to register its own trampolines to be called by
           the ftrace nop locations directly, without going through the ftrace
           trampoline, this function has been added. This allows for eBPF
           trampolines to live along side of ftrace, perf, kprobe and live
           patching. It also utilizes the ftrace enabled_functions file that
           keeps track of functions that have been modified in the kernel, to
           allow for security auditing.
      
         - Allow for kernel internal use of ftrace instances.
      
           Subsystems in the kernel can now create and destroy their own
           tracing instances which allows them to have their own tracing
           buffer, and be able to record events without worrying about other
           users from writing over their data.
      
         - New seq_buf_hex_dump() that lets users use the hex_dump() in their
           seq_buf usage.
      
         - Notifications now added to tracing_max_latency to allow user space
           to know when a new max latency is hit by one of the latency
           tracers.
      
         - Wider spread use of generic compare operations for use of bsearch
           and friends.
      
         - More synthetic event fields may be defined (32 up from 16)
      
         - Use of xarray for architectures with sparse system calls, for the
           system call trace events.
      
        This along with small clean ups and fixes"

      Pull powerpc Spectre-RSB fixes from Michael Ellerman:
       "We failed to activate the mitigation for Spectre-RSB (Return Stack
        Buffer, aka. ret2spec) on context switch, on CPUs prior to Power9
        DD2.3.
      
        That allows a process to poison the RSB (called Link Stack on Power
        CPUs) and possibly misdirect speculative execution of another process.
        If the victim process can be induced to execute a leak gadget then it
        may be possible to extract information from the victim via a side
        channel.
      
        The fix is to correctly activate the link stack flush mitigation on
        all CPUs that have any mitigation of Spectre v2 in userspace enabled.
      
        There's a second commit which adds a link stack flush in the KVM guest
        exit path. A leak via that path has not been demonstrated, but we
        believe it's at least theoretically possible.

      net: wireless: intel: iwlwifi: fix GRO_NORMAL packet stalling · b167191e
      Alexander Lobakin authored
      Commit 6570bc79 ("net: core: use listified Rx for GRO_NORMAL in
      napi_gro_receive()") has applied batched GRO_NORMAL packets processing
      to all napi_gro_receive() users, including mac80211-based drivers.
      
      However, this change has led to a regression in iwlwifi driver [1][2] as
      it is required for NAPI users to call napi_complete_done() or
      napi_complete() and the end of every polling iteration, whilst iwlwifi
      doesn't use NAPI scheduling at all and just calls napi_gro_flush().
      In that particular case, packets which have not been already flushed
      from napi->rx_list stall in it until at least next Rx cycle.
      
      Fix this by adding a manual flushing of the list to iwlwifi driver right
      before napi_gro_flush() call to mimic napi_complete() logics.
      
      I prefer to open-code gro_normal_list() rather than exporting it for 2
      reasons:
      * to prevent from using it and napi_gro_flush() in any new drivers,
        as it is the *really* bad way to use NAPI that should be avoided;
      * to keep gro_normal_list() static and don't lose any CC optimizations.
      
      I also don't add the "Fixes:" tag as the mentioned commit was only a
      trigger that only exposed an improper usage of NAPI in this particular
      driver.

       "Here is the "big" set of driver core patches for 5.5-rc1
      
        There's a few minor cleanups and fixes in here, but the majority of
        the patches in here fall into two buckets:
      
         - debugfs api cleanups and fixes
      
         - driver core device link support for boot dependancy issues
      
        The debugfs api cleanups are working to slowly refactor the debugfs
        apis so that it is even harder to use incorrectly. That work has been
        happening for the past few kernel releases and will continue over
        time, it's a long-term project/goal
      
        The driver core device link support missed 5.4 by just a bit, so it's
        been sitting and baking for many months now. It's from Saravana Kannan
        to help resolve the problems that DT-based systems have at boot time
        with dependancy graphs and kernel modules. Turns out that no one has
        actually tried to build a generic arm64 kernel with loads of modules
        and have it "just work" for a variety of platforms (like a distro
        kernel). The big problem turned out to be a lack of dependency
        information between different areas of DT entries, and the work here
        resolves that problem and now allows devices to boot properly, and
        quicker than a monolith kernel.
      
        All of these patches have been in linux-next for a long time with no
        reported issues"

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for v5.5.
      
        It is pretty much business as usual, the most interesting thing I
        think is the pin controller for a new Intel chip called Lightning
        Mountain, which is according to news reports some kind of embedded
        network processor and what is surprising about it is that Intel have
        decided to use device tree to describe the system rather than ACPI
        that they have traditionally favored.
      
        Core changes:
      
         - Avoid taking direct references to device tree-supplied device
           names: these may changed at runtime under certain circumstances to
           kstrdup them.
      
        GPIO related:
      
         - Work is ongoing to move to passing the irqchip along as a templated
           struct gpio_irq_chip when adding a standard gpiolib-based irqchip
           to a GPIO controller, a few patches in this cycle switches a few
           pin control drivers over to using this method.
      
        New hardware support:
      
         - Intel Lightning Mountain SoC pin controller and GPIO support, a
           first Intel platform to use device tree rather than ACPI to
           configure the system. News reports says that this SoC is a network
           processor.
      
         - Qualcomm MSM8976 and MSM8956
      
         - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
      
         - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
      
         - Rockchip RK3308
      
         - Renesas R8A77961
      
         - Allwinner Meson-A1
      
        Driver improvements:
      
         - get_multiple and set_multiple support for the AT91-PIO4 driver.
      
         - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in
           the GPIOlib irqchip"

       "There have been some significant changes in the core side, both for
        ALSA and ASoC, while lots of development have been seen in SOF, as
        well as many small fixes/improvements for ASoC codecs and platforms.
        Below is a highlight in this cycle:
      
        Core:
         - The unification of PCM vmalloc buffer allocation helpers into the
           standard API
         - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
         - Fix potential races at ALSA timer open
         - A few new PCM API extensions; just preliminary core changes, the
           actual changes in drivers will be merged in 5.6
         - Continued ASoC componentization works; now almost everything is a
           common ASoC component object. A lot of refactoring and
           simplification have been done along with it.
      
        ASoC:
         - Many fixes to the Sound Open Firmware (SOF) code
         - Wake on voice support for Chromebooks
         - SPI support and trigger word detection for RT5677
         - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
           with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
      
        HD-audio:
         - Improved Intel DSP configuration / probe code for SOF
         - Plumbing the legacy HD-audio driver with Intel SOF HDMI
         - DP-MST support for Nvidia HDMI codecs
         - Realtek quirks cleanups and new additions as usual
      
        Others:
         - Lots of refactoring and cleanups for FireWire; period-size sharing,
           h/w IRQ interval configuration, clock recovery improvements, etc
         - USB-audio: Scarlett mixer quirks
         - Cleanups of PCM calls in various drivers (including media and USB)

        idle states in the idle loop, some cpuidle fixes and governor updates,
        assorted cpufreq updates (driver updates mostly and a few core fixes
        and cleanups), devfreq updates (dominated by the tegra30 driver
        changes), new CPU IDs for the RAPL power capping driver, relatively
        minor updates of the generic power domains (genpd) and operation
        performance points (OPP) frameworks, and assorted fixes and cleanups.
      
        There are also two maintainer information updates: Chanwoo Choi will
        be maintaining the devfreq subsystem going forward and Todd Brandt is
        going to maintain the pm-graph utility (created by him).
      
        Specifics:
      
         - Use nanoseconds (instead of microseconds) as the unit of time in

           limit for idle states to be specified (Daniel Lezcano)
      
         - Fix cpufreq driver registration and clarify a comment in the
           cpufreq core (Viresh Kumar)
      
         - Add NULL checks to the show() and store() methods of sysfs
           attributes exposed by cpufreq (Kai Shen)

         - Appoint Chanwoo Choi as the new devfreq maintainer.
      
         - Update the devfreq core:
            * Check NULL governor in available_governors_show sysfs to prevent
              showing wrong governor information and fix a race condition
              between devfreq_update_status() and trans_stat_show() (Leonard
              Crestez)
            * Add new 'interrupt-driven' flag for devfreq governors to allow
              interrupt-driven governors to prevent the devfreq core from
              polling devices for status (Dmitry Osipenko)
            * Improve an error message in devfreq_add_device() (Matthias
              Kaehlcke)

           framework (Stephen Boyd)
      
         - Avoid freeing memory that has never been allocated in the
           hibernation core (Andy Whitcroft)
      
         - Clean up function headers in a header file and coding style in the

        The load-balancing rework is the most intrusive change: it replaces
        the old heuristics that have become less meaningful after the
        introduction of the PELT metrics, with a grounds-up load-balancing
        algorithm.
      
        As such it's not really an iterative series, but replaces the old
        load-balancing logic with the new one. We hope there are no
        performance regressions left - but statistically it's highly probable
        that there *is* going to be some workload that is hurting from these

      openvswitch: fix flow command message size · 4e81c0b3
      Paolo Abeni authored
      When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant
      flow has no UFID, we can exceed the computed size, as
      ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY
      attribute.
      Take the above in account when computing the flow command message
      size.

      net: psample: fix skb_over_panic · 7eb9d767
      Nikolay Aleksandrov authored
      We need to calculate the skb size correctly otherwise we risk triggering
      skb_over_panic[1]. The issue is that data_len is added to the skb in a
      nl attribute, but we don't account for its header size (nlattr 4 bytes)
      and alignment. We account for it when calculating the total size in
      the > PSAMPLE_MAX_PACKET_SIZE comparison correctly, but not when
      allocating after that. The fix is simple - use nla_total_size() for
      data_len when allocating.
      
      To reproduce:
       $ tc qdisc add dev eth1 clsact
       $ tc filter add dev eth1 egress matchall action sample rate 1 group 1 trunc 129
       $ mausezahn eth1 -b bcast -a rand -c 1 -p 129
