The s390 BFP compiler currently uses relative branch instructions that only support jumps up to 64 KB. Examples are "j", "jnz", "cgrj", etc. Currently the maximum size of s390 BPF programs is set to 0x7ffff. If branches over 64 KB are generated the, kernel can crash due to incorrect code. So fix this an reduce the maximum size to 64 KB. Programs larger than that will be interpreted. Fixes: ce2b6ad9 ("s390/bpf: increase BPF_SIZE_MAX") Cc: stable@vger.kernel.org # 4.3+ Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Pull tracing updates from Steven Rostedt: "This includes two new updates for the ftrace infrastructure. - With the changing of the code for filtering events by pid, from a list of pids to a bitmask, we can now easily implement following forks. With a new tracing option "event-fork" which, when set, will have tasks with pids in set_event_pid, when they fork, to have their child pids added to set_event_pid and the child will be traced as well. Note, if "event-fork" is set and a task with its pid in set_event_pid exits, its pid will be removed from set_event_pid - The addition of Tom Zanussi's hist triggers. This includes a very thorough documentatino on how to use the hist triggers with events. This introduces a quick and easy way to get histogram data from events and their fields. Some other cleanups and updates were added as well. Like Masami Hiramatsu added test cases for the event trigger and hist triggers. Also I added a speed up of filtering by using a temp buffer when filters are set" * tag 'trace-v4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (45 commits) tracing: Use temp buffer when filtering events tracing: Remove TRACE_EVENT_FL_USE_CALL_FILTER logic tracing: Remove unused function trace_current_buffer_lock_reserve() tracing: Remove one use of trace_current_buffer_lock_reserve() tracing: Have trace_buffer_unlock_commit() call the _regs version with NULL tracing: Remove unused function trace_current_buffer_discard_commit() tracing: Move trace_buffer_unlock_commit{_regs}() to local header tracing: Fold filter_check_discard() into its only user tracing: Make filter_check_discard() local tracing: Move event_trigger_unlock_commit{_regs}() to local header tracing: Don't use the address of the buffer array name in copy_from_user tracing: Handle tracing_map_alloc_elts() error path correctly tracing: Add check for NULL event field when creating hist field tracing: checking for NULL instead of IS_ERR() tracing: Do not inherit event-fork option for instances tracing: Fix unsigned comparison to zero in hist trigger code kselftests/ftrace: Add a test for log2 modifier of hist trigger tracing: Add hist trigger 'log2' modifier kselftests/ftrace: Add hist trigger testcases kselftests/ftrace : Add event trigger testcases ...

Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, these contain various things that touch the drivers/ directory but got merged through arm-soc for practical reasons. For the most part, this is now related to power management controllers, which have not yet been abstracted into a separate subsystem, and typically require some code in drivers/soc or arch/arm to control the power domains. Another large chunk here is a rework of the NVIDIA Tegra USB3.0 support, which was surprisingly tricky and took a long time to get done.

Pull ARM 64-bit DT updates from Arnd Bergmann: "We continue ramping up platform support for 64-bit ARM machines, with 111 individual non-merge changesets touching 21 platforms. The LG1312 platform is completely new and is the first ARM platform by LG that we support in the mainline kernel. Two other SoCs got added that are updated versions of existing SoC families, so the port mainly consists of new dts files: - The Hisilicon Hip06/D03 is the latest server platform from Huawei/Hisilicon, and follows the Hip05/D02 platform. - Rockchip RK3399 follows the 32-bit RK3288 that is popular in low-end Chromebooks and the 64-bit RK3368 that is mainly found in chinese Android TV boxes. The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a long-awaited overhaul with a lot of devices enabled in the DT, so it should be much more usable with a mainline kernel now. See also https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd A lot of work went into enabling new device drivers on existing machines, but we also have a couple of new commercially available machines: - Google Pixel C laptop based on Tegra210 - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905) - Geekbuying GeekBox based on Rockchip RK3368 And finally, a couple of reference or development platforms that are not end-user platforms but are used for trying out the respective SoC platforms: - Amlogic Meson GXBB P200 and P201 development systems - NXP Layerscape 1043A QDS development board - Hisilicon Hip06 D03 server board, as mentioned above - LG1312 Reference Design - RK3399 Evaluation Board" * tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (104 commits) arm64: dts: marvell: add XOR node for Armada 3700 SoC dt-bindings: document rockchip rk3399-evb board arm64: dts: rockchip: add dts file for RK3399 evaluation board arm64: dts: rockchip: add core dtsi file for RK3399 SoCs dt-bindings: rockchip-dw-mshc: add description for rk3399 arm64: dts: marvell: Use a SoC-specific compatible for xHCI on Armada37xx arm64: dts: marvell: Rename armada-37xx USB node arm64: dts: marvell: Clean up armada-3720-db Documentation: arm64: Add Hisilicon Hip06 D03 dts binding arm64: dts: Add initial dts for Hisilicon Hip06 D03 board arm64: dts: hip05: Add nor flash support arm64: dts: hip05: fix its node without msi-cells arm64: dts: r8a7795: Don't disable referenced optional clocks arm64: dts: salvator-x: populate EXTALR arm64: dts: r8a7795: enable PCIe on Salvator-X arm64: dts: r8a7795: Add PCIe nodes arm64: tegra: Add IOMMU node to GM20B on Tegra210 arm64: tegra: Add reference clock to GM20B on Tegra210 dt-bindings: Add documentation for GM20B GPU dt-bindings: gk20a: Document iommus property ...

Pull ARM DT updates from Arnd Bergmann: "These are all the updates to device tree files for 32-bit platforms, which as usual makes up the bulk of the ARM SoC changes: 462 non-merge changesets, 450 files changed, 23340 insertions, 5216 deletions. The three platforms that are added with the "soc" branch are here as well, and we add some related machine files: - For Aspeed AST2400/AST2500, we get the evaluation platform and the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC - For Oxnas 810SE, the Western Digital "My Book World Edition" is added as the only platform at the moment. - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7) are supported On the ARM Realview development platform, we now support all machines with device tree, previously only the board files were supported, which in turn will likely be removed soon.

Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (42 commits) MAINTAINERS: ARM/Amlogic: add co-maintainer, misc. updates MAINTAINERS: add ARM/NXP LPC32XX SoC specific drivers to the section MAINTAINERS: add new maintainers of NXP LPC32xx SoC MAINTAINERS: move ARM/NXP LPC32xx record to ARM section arm: Add Aspeed machine ARM: lpc32xx: remove duplicate const on lpc32xx_auxdata_lookup ARM: lpc32xx: remove leftovers of legacy clock source and provider drivers ARM: lpc32xx: remove reboot header file ARM: dove: Remove CLK_IS_ROOT ARM: orion5x: Remove CLK_IS_ROOT ARM: mv78xx0: Remove CLK_IS_ROOT ARM: davinci: da850: use clk->set_parent for async3 ARM: davinci: Move clock init after ioremap.

My laptop that uses the intel 7680 iwlwifi module would no longer connects to the network. It would fail with a "Microcode SW error detected." and spew out register state over and over again without ever connecting to the network. The cause is mis-merge in commit 909b27f7, where David seems to have lost some of the changes to iwl_mvm_set_tx_cmd() from commit 5c08b0f5 ("iwlwifi: mvm: don't override the rate with the AMSDU len"). The reason seems to be a conflict with commit d8fe4844 ("iwlwifi: mvm: add support for new TX CMD API"), which touched a line adjacent to the changes in 909b27f7. David missed the fact that "info->driver_data[0]" had become "skb_info->driver_data[0]". Then he removed the skb_info because it was unused. This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

There's a three-process deadlock involving shared/exclusive barriers and inverted lock orders in the directory readdir implementation. It's a pre-existing problem with lock ordering, exposed by the VFS parallelisation code. process 1 process 2 process 3 --------- --------- --------- readdir iolock(shared) get_leaf_dents iterate entries ilock(shared) map, lock and read buffer iunlock(shared) process entries in buffer ..... readdir iolock(shared) get_leaf_dents iterate entries ilock(shared) map, lock buffer <blocks> finish ->iterate_shared file_accessed() ->update_time start transaction ilock(excl) <blocks> ..... finishes processing buffer get next buffer ilock(shared) <blocks> And that's the deadlock. Fix this by dropping the current buffer lock in process 1 before trying to map the next buffer. This means we keep the lock order of ilock -> buffer lock intact and hence will allow process 3 to make progress and drop it's ilock(shared) once it is done.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for kernel cycle v4.7: Core infrastructural changes: - Support for natively single-ended GPIO driver stages. This means that if the hardware has registers to configure open drain or open source configuration, we use that rather than (as we did before) try to emulate it by switching the line to an input to get high impedance. This is also documented throughly in Documentation/gpio/driver.txt for those of you who did not understand one word of what I just wrote. - Start to do away with the unnecessarily complex and unitelligible ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from the time when the GPIO subsystem was unmaintained. Archs can now just select GPIOLIB and be done with it, cleanups to arches will trickle in for the next kernel. Some minor archs ACKed the changes immediately so these are included in this pull request. - Advancing the use of the data pointer inside the GPIO device for storing driver data by switching the PowerPC, Super-H Unicore and a few other subarches or subsystem drivers in ALSA SoC, Input, serial, SSB, staging etc to use it. - The initialization now reads the input/output state of the GPIO lines, so that each GPIO descriptor knows - if this callback is implemented - whether the line is input or output. This also reflects nicely in userspace "lsgpio". - It is now possible to name GPIO producer names, line names, from the device tree. (Platform data has been supported for a while). I bet we will get a similar mechanism for ACPI one of those days. This makes is possible to get sensible producer names for e.g. GPIO rails in "lsgpio" in userspace. New drivers: - New driver for the Loongson1. - The XLP driver now supports Broadcom Vulcan ARM64. - The IT87 driver now supports IT8620 and IT8628. - The PCA953X driver now supports Galileo Gen2. Driver improvements: - MCP23S08 was switched to use the gpiolib irqchip helpers and now also suppors level-triggered interrupts. - 74x164 and RCAR now supports the .set_multiple() callback - AMDPT was converted to use generic GPIO. - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994 support the new single ended callback for open drain and in some cases open source. - Implement the .get_direction() callback for a few more drivers like PL061, Xgene. Cleanups: - Paul Gortmaker combed through the drivers and de-modularized those who are not really modules. - Move the GPIO poweroff DT bindings to the power subdir where they belong. - Rename gpio-generic.c to gpio-mmio.c, which is much more to the point.

The btrfs_{set,remove}xattr inode operations check for a read-only root (btrfs_root_readonly) before calling into generic_{set,remove}xattr. If this check is moved into __btrfs_setxattr, we can get rid of btrfs_{set,remove}xattr.

Ubifs internally uses special inodes for storing xattrs. Those inodes had NULL {get,set,remove}xattr inode operations before this change, so xattr operations on them would fail. The super block's s_xattr field would also apply to those special inodes. However, the inodes are not visible outside of ubifs, and so no xattr operations will ever be carried out on them anyway.
