Pull tracing updates from Steven Rostedt: "The biggest change here is the updates to kprobes Back in January I posted patches to create function based events. These were the events that you suggested I make to allow developers to easily create events in code where no trace event exists. After posting those changes for review, it was suggested that we implement this instead with kprobes. The problem with kprobes is that the interface is too complex and needs to be simplified. Masami Hiramatsu posted patches in March and I've been playing with them a bit. There's been a bit of clean up in the kprobe code that was inspired by the function based event patches, and a couple of enhancements to the kprobe event interface. - If the arch supports it (we added support for x86), you can place a kprobe event at the start of a function and use $arg1, $arg2, etc to reference the arguments of a function. (Before you needed to know what register or where on the stack the argument was). - The second is a way to see array of events. For example, if you reference a mac address, you can add: echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events And this will produce: mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec} Other changes include - Exporting trace_dump_stack to modules - Have the stack tracer trace the entire stack (stop trying to remove tracing itself, as we keep removing too much). - Added support for SDT in uprobes" [ SDT - "Statically Defined Tracing" are userspace markers for tracing. Let's not use random TLA's in explanations unless they are fairly well-established as generic (at least for kernel people) - Linus ] * tag 'trace-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (24 commits) tracing: Have stack tracer trace full stack tracing: Export trace_dump_stack to modules tracing: probeevent: Fix uninitialized used of offset in parse args tracing/kprobes: Allow kprobe-events to record module symbol tracing/kprobes: Check the probe on unloaded module correctly tracing/uprobes: Fix to return -EFAULT if copy_from_user failed tracing: probeevent: Add $argN for accessing function args x86: ptrace: Add function argument access API tracing: probeevent: Add array type support tracing: probeevent: Add symbol type tracing: probeevent: Unify fetch_insn processing common part tracing: probeevent: Append traceprobe_ for exported function tracing: probeevent: Return consumed bytes of dynamic area tracing: probeevent: Unify fetch type tables tracing: probeevent: Introduce new argument fetching code tracing: probeevent: Remove NOKPROBE_SYMBOL from print functions tracing: probeevent: Cleanup argument field definition tracing: probeevent: Cleanup print argument functions trace_uprobe: support reference counter in fd-based uprobe perf probe: Support SDT markers having reference counter (semaphore) ...

Pull ARM SoC platform updates from Arnd Bergmann: "A couple of platforms change hands in the MAINTAINERS file: - Linus Walleij lists himself for the ARM Reference platforms: versatile, vexpress, integrator and realview. He has been the main contributor for these for a while, and makes it official now. - Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood - Manivannan Sadhasivam becomes a secondary maintainer for the Actions Semi machines - Nicolas Ferre lists updates the MAINTAINER listing for the AT91 platform: Ludovic Desroches is now a co-maintainer for the platform, and several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev, Codrin Ciubotariu) take over individual device drivers. Thanks everyone for working on this, and welcome to the new maintainers! The "virt" platform on qemy or kvm can now be used in big-endian mode without additional tricks, thanks to Jason Donenfeld. Once again, we gain support for another NXP i.MX6 variant, this time it's the i.MX 6ULZ 32-bit single-core version. On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0) and RZ/G2M (r8a774a1). These are described as microcontrollers on the manufacturer website, but appear to be rather powerful.

Pull ARM SoC driver updates from Arnd Bergmann: "The most noteworthy SoC driver changes this time include: - The TEE subsystem gains an in-kernel interface to access the TEE from device drivers. - The reset controller subsystem gains a driver for the Qualcomm Snapdragon 845 Power Domain Controller. - The Xilinx Zynq platform now has a firmware interface for its platform management unit. This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller. Additional cleanups and bugfixes in SoC specific drivers include the Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (129 commits) firmware: tegra: bpmp: Implement suspend/resume support drivers: clk: Add ZynqMP clock driver dt-bindings: clock: Add bindings for ZynqMP clock driver firmware: xilinx: Add zynqmp IOCTL API for device control Documentation: xilinx: Add documentation for eemi APIs MAINTAINERS: imx: include drivers/firmware/imx path firmware: imx: add misc svc support firmware: imx: add SCU firmware driver support reset: Fix potential use-after-free in __of_reset_control_get() dt-bindings: arm: fsl: add scu binding doc soc: fsl: qbman: add interrupt coalesce changing APIs soc: fsl: bman_portals: defer probe after bman's probe soc: fsl: qbman: Use last response to determine valid bit soc: fsl: qbman: Add 64 bit DMA addressing requirement to QBMan soc: fsl: qbman: replace CPU 0 with any online CPU in hotplug handlers soc: fsl: qbman: Check if CPU is offline when initializing portals reset: qcom: PDC Global (Power Domain Controller) reset controller dt-bindings: reset: Add PDC Global binding for SDM845 SoCs reset: Grammar s/more then once/more than once/ bus: ti-sysc: Just use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS ...

Pull ARM SoC device tree updates from Arnd Bergmann: "There are close to 800 indivudal changesets in this branch again, which feels like a lot. There are particularly many changes for the NVIDIA Tegra platform this time, in fact more than it has seen in the two years since the v4.9 merge window. Aside from this, it's been fairly normal, with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP. Most of the changes are for adding new features into existing boards, for brevity I'm only mentioning completely new machines and SoCs here. For the first time I think we have (slightly) more new 64-bit hardware than 32-bit: Two boards get added for TI OMAP: Moxa UC-2101 is an industrial computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a minor variation of the motherboards of the GTA04 phone, see https://shop.goldelico.com/wiki.php?page=GTA04A5 Clearfog is a nice little board for quad-core Marvell Armada 8040 network processor, see https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/ Two additional server boards come with the Aspeed baseboard management controllers: Stardragon4800 is an arm64 reference platform made by HXT (based on Qualcomm's server chips), and TiogaPass is an Open Compute mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the BMC. NXP i.MX usually sees a lot of new boards each release. This time there we only add one minor variant: ConnectCore 6UL SBC Pro uses the same SoM design as the ConnectCore 6UL SBC Express added later. However, there is a new chip, the i.MX6ULZ, which is an even smaller variant of the i.MX6ULL, with features removed. There is also support for the reference board design, the i.MX6ULZ 14x14 EVK. A new Raspberry Pi variant gets added, this one is the CM3 compute module based on bcm2837, it was launched in early 2017 but only now added to the kernel, both as 32-bit and as 64-bit files, as we tend to do for Raspberry Pi. On the Allwinner side, everything is again about cheap development boards, usually of the "Fruit Pi" variety. The new ones this time are: - Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/ - Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/ - Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts - Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html The last one of these is now a 64-bit version of the earlier Banana Pi M2+ H3, with the same board layout. Similarly, for Rockchips, get get another variant of the 32-bit Asus Tinker board, the model 'S' based on rk3288, and three now boards based on the popular RK3399 chip: - ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/ - Rock960: https://www.96boards.org/product/rock960/ - RockPro64: https://www.pine64.org/?page_id=61454 These are all quite powerful boards with lots of RAM and I/O, and the RK3399 is the same chip used in several Chromebooks. Finally, we get support for the PX30 (aka rk3326) chip, which is based on the low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board is supported. One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based on the MT7622 WiFi router platform, and the first product I've seen with a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370 development board, which are similar to the Hi3660 and Hikey 360 respectively, but add support for an NPU. Amlogic gets initial support for the Meson-G12A chip (S905D2), another quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit side, we gain support for an actual end-user product, the Endless Computers Endless Mini based on Meson8b (S805), see https://endlessos.com/computers/ Qualcomm adds support for their MSM8998 SoC and evaluation platform. This chip is commonly known as the Snapdragon 835, and is used in high-end phones as well as low-end laptops. For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added, but no boards for this one. However, we do add boards for the previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB Starter Kit Pro. While we have lots of DT changes for NVIDIA to update the existing files, the only board that gets added is the Toradex Colibri T20 on Colibri Evaluation Board for the old Tegra2. Synaptics add support for their AS370 SoC, which is part of the (formerly Marvell) Berlin line of set-top-box chips used e.g. in the various Google Chromecast.

This has changed since following commits: 05aa55dd ("PM / Runtime: Lenient generic runtime pm callbacks") 543f2503 ("PM / platform_bus: Allow runtime PM by default") 8b313a38 ("PM / Platform: Use generic runtime PM callbacks directly") Signed-off-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Reviewed-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

The current IRQ handler clears all the IRQ status bits when it bails out. This is dangerous because it might clear away the status bits that have just been set while processing the current handler. If this happens, the IRQ event for the latest transfer is lost forever. The IRQ status bits must be cleared *before* the next transfer is kicked.

Currently, a timeout error could happen at a repeated START condition. For a (non-repeated) START condition, the controller starts sending data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated START condition, the hardware starts running when the slave address is written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is actually unneeded. Because the hardware is already running before the IRQ is enabled for a repeated START, the driver may miss the IRQ event. In most cases, this problem does not show up since modern CPUs are much faster than the I2C transfer. However, it is still possible that a context switch happens after the controller starts, but before the IRQ register is set up. To fix this, - Do not write UNIPHIER_FI2C_CR for repeated START conditions. - Enable IRQ *before* writing the slave address to the TX FIFO. - Disable IRQ for the current CPU while queuing up the TX FIFO; If the CPU is interrupted by some task, the interrupt handler might be invoked due to the empty TX FIFO before completing the setup.

This is unlikely to happen, but it is possible for a CPU to enter the interrupt handler just after wait_for_completion_timeout() has expired. If this happens, the hardware is accessed from multiple contexts concurrently. Disable the IRQ after wait_for_completion_timeout(), and do nothing from the handler when the IRQ is disabled.

Commit 1ff2e1a4 ("HID: input: Create a utility class for counting scroll events") created the helper function hid_scroll_counter_handle_scroll() to handle high-res scroll events and also expose them as regular wheel events. But the resulting algorithm was unstable, and causes scrolling to be very unreliable. When you hit the half-way mark of the highres multiplier, small highres movements will incorrectly translate into big traditional wheel movements, causing odd jitters. Simplify the code and make the output stable. NOTE! I'm pretty sure this will need further tweaking. But this at least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into a usable one.

"LTP, Lmbench ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines We'll continouslly improve csky subsystem in future" Arnd acks, and adds the following notes: "I did a thorough review of the ABI, which as usual mainly consists of spotting any files that don't use the asm-generic ABI itself, and having it changed to it matches exactly what we do on other new architectures. I also looked at every other patch and commented on maybe half of them where I saw something that did not quite seem right. Others have reviewed specific patches in greater depth. I'm sure that one could fine more of the minor details, but as long as they are not ABI relevant, they can be fixed later. The only patch that is part of the ABI and that nobody reviewed is the signal handling. This is one of the areas I never worked on in much detail. I did not see anything wrong with it, but I also don't know what the problems with the other architectures are here, and we seem to be hitting issues occasionally, and we never managed to generalize this enough for new architectures to have a trivial implementation. I was originally hoping that we could have the 64-bit time_t interfaces ready in time to completely drop the 32-bit ones, but that did not happen. We might still remove them in the next merge window depending on whether the libc upstream people prefer to keep them or not. One more general comment: I think this may well be the last new CPU architecture we ever add to the kernel. Both nds32 and c-sky are made by companies that also work on risc-v, and generally speaking risc-v seems to be killing off any of the minor licensable instruction set projects, just like ARM has mostly killed off the custom vendor-specific instruction sets already. If we add another architecture in the future, it may instead be something like the LLVM bitcode or WebAssembly, who knows?"

Since its inception, udp_dump_one has had a bug where userspace needs to swap src and dst addresses and ports in order to find the socket it wants. This is because it passes the socket source address to __udp[46]_lib_lookup's saddr argument, but those functions are intended to find local sockets matching received packets, so saddr is the remote address, not the local address. This can no longer be fixed for backwards compatibility reasons, so add a brief comment explaining that this is the case. This will avoid confusion and help ensure SOCK_DIAG implementations of new protocols don't have the same problem.

Radu Rendec proposed another version of the first patch [0] but I'd rather not follow the behavior of vlan devices, going with macvlan does instead. Patrick Talbert also reported the same issue to me. The second patch is a follow-up. The restriction on setting the device up is a bit unreasonable, and operstate provides the information we need in this case.

Currently, the kernel doesn't let the administrator set a macsec device up unless its lower device is currently up. This is inconsistent, as a macsec device that is up won't automatically go down when its lower device goes down. Now that linkstate propagation works, there's really no reason for this limitation, so let's remove it.

Like all other virtual devices (macvlan, vlan), the operstate of a macsec device should match the state of its lower device. This is done by calling netif_stacked_transfer_operstate from its netdevice notifier. We also need to call netif_stacked_transfer_operstate when a new macsec device is created, so that its operstate is set properly. This is only relevant when we try to bring the device up directly when we create it. Radu Rendec proposed a similar patch, inspired from the 802.1q driver, that included changing the administrative state of the macsec device, instead of just the operstate. This version is similar to what the macvlan driver does, and updates only the operstate.
