2018-06-12skip LAYOUTRETURN if layout is invalidOlga Kornievskaia
Currently, when IO to DS fails, client returns the layout and retries against the MDS. However, then on umounting (inode eviction) it returns the layout again. This is because pnfs_return_layout() was changed in commit d78471d32bb6 ("pnfs/blocklayout: set PNFS_LAYOUTRETURN_ON_ERROR") to always set NFS_LAYOUT_RETURN_REQUESTED so even if we returned the layout, it will be returned again. Instead, let's also check if we have already marked the layout invalid. Signed-off-by: Olga Kornievskaia <kolga@netapp.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree updates from Olof Johansson: "As always, a large number of DT updates. Too many to enumerate them all, but at a glance: New SoCs introduced in this release: - Amlogic: + Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some set top boxes and other products. - Mediatek: + MT7623A, which is a flavor of the MT7623 family with other on-chip ethernet options. - Qualcomm: + SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845 (Cortex-A75/A55 derivative) SoC that's one of the current high-end mobile SoCs. It's great to see mainline support for it. So far, you can't do much with it, since a lot of peripherals are not yet in the DTs but driver support for USB, GPU and other pieces are starting to trickle in. This might end up being a well-supported SoC upstream if the momentum keeps up. - Renesas: + R8A77990, a.k.a R-Car E3, a new automotive entertainment-targeted SoC. Currently only one Cortex-A53 CPU is enabled, we are eagerly awaiting more. So far, basic drivers such as serial, gpios, PMU and ethernet are enabled. + R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR GPU. Same here, basic set of drivers such as serial, gpios and ethernet enabled, and SMP support is also forthcoming. - STMicroelectronics: + STM32F469, very similar tih STM32F429 but with display support Enhancements to SoCs/platforms (DTS contents, some driver portions might not be in yet): - Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc - Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets - Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces - Marvell Berlin2CD: SMP support, thermal sensors - Mediatek MT7623: Highspeed DMA, audio support - Qualcomm IPQ8074 PCIe support, MSM8996 UFS support - Renesas: Watchdog and PMU support across many platforms - Rockchip RK3399: USB3 OTG support - Samsung Exynos: Audio-over-HDMI on Odroid X/X2/U3 - STMicro STM32: Lots of peripherals added to STM32MP175C - Uniphier: Ethernet support New boards: - Allwinner A20: Olimex A20-SOM-EVB-eMMC variant - Allwinner H2+: Libre Computer ALL-H3-CC (h2+ version) - Allwinner A33: Nintendo NES/SuperNES Classic Edition - Aspeed: S2600WF, Inventec Lanyang BMC, Portwell Neptune - Berlin2CD: Valve Steam Link - Broadcom BCM5301X: Luxul XAP-1610 and XWR-3150 V1 - Broadcom: Raspberry Pi 3 B+ - Mediatek MT7623N and MT7623A: reference boards - Meson 8M2: Tronsmart MXIII Plus - NXP i.MX: Engicam i.CoreM6, DHCOM iMX6 SOM, BTicino i.MX6DL Mamoj - Qualcomm MSM8974: Sony Xperia Z1 Compact support - Qualcomm SDM845: MTP development board - Renesas: Ebisu R8A77990 board - Renesas RZ/G1C: iwg23s: iWave G235-SDB - TI am335x: Pocketbeagle support" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (448 commits) ARM: dts: aspeed: Fix hwrng register address arm64: dts: sprd: whale2: Add the rtc enable clock for watchdog arm64: dts: sprd: Add GPIO and GPIO keys device nodes arm64: dts: sprd: fix typo in 'remote-endpoint' arm64: dts: apq8096-db820c: Removed bt-en-1-8v regulator arm64: dts: fix regulator property name for wlan pcie endpoint arm64: dts: qcom: msm8996: Use UFS_GDSC for UFS ARM: dts: pxa3xx: fix MMC clocks ARM: pxa: dts: add pin definitions for extended GPIOs ARM: pxa: dts: add gpio-ranges to gpio controller ARM: dts: ipq8074: Enable few peripherals for hk01 board ARM: dts: ipq8074: Add pcie nodes ARM: dts: ipq8074: Add peripheral nodes ARM: dts: ipq4019: Add qcom-ipq4019-ap.dk07.1-c2 board file ARM: dts: ipq4019: Add qcom-ipq4019-ap.dk07.1-c1 board file ARM: dts: ipq4019: Add ipq4019-ap.dk07.1 common data ARM: dts: ipq4019: Add qcom-ipq4019-ap.dk04.1-c3 board file ARM: dts: ipq4019: Add ipq4019-ap.dk04.1-c1 board file ARM: dts: ipq4019: Add ipq4019-ap.dk04.dtsi ARM: dts: ipq4019: Change the max opp frequency ...

dma_direct_{alloc,free}()" This reverts commit b468620f2a1dfdcfddfd6fa54367b8bcc1b51248. It turns out that this broke drm on AMD platforms. Quoting Gabriel C: "I can confirm reverting b468620f2a1dfdcfddfd6fa54367b8bcc1b51248 fixes that issue for me. The GPU is working fine with SME enabled. Now with working GPU :) I can also confirm performance is back to normal without doing any other workarounds" Christan König analyzed it partially: "As far as I analyzed it we now get an -ENOMEM from dma_alloc_attrs() in drivers/gpu/drm/ttm/ttm_page_alloc_dma.c when IOMMU is enabled" and Christoph Hellwig responded: "I think the prime issue is that dma_direct_alloc respects the dma mask. Which we don't need if actually using the iommu. This would be mostly harmless exept for the the SEV bit high in the address that makes the checks fail.

2018-06-11autofs: remove left-over autofs4 stubsLinus Torvalds
There's no need to retain the fs/autofs4 directory for backward compatibility. Adding an AUTOFS4_FS fragment to the autofs Kconfig and a module alias for autofs4 is sufficient for almost all cases. Not keeping fs/autofs4 remnants will prevent "insmod <path>/autofs4/autofs4.ko" from working but this shouldn't be used in automation scripts rather than modprobe(8). There were some comments about things to look out for with the module rename in the fs/autofs4/Kconfig that is removed by this patch, see the commit patch if you are interested. One potential problem with this change is that when the fs/autofs/Kconfig fragment for AUTOFS4_FS is removed any AUTOFS4_FS entries will be removed from the kernel config, resulting in no autofs file system being built if there is no AUTOFS_FS entry also. This would have also happened if the fs/autofs4 remnants had remained and is most likely to be a problem with automated builds. Please check your build configurations before the removal which will occur after the next couple of kernel releases.

2018-06-11backlight: as3711_bl: Fix Device Tree node leaksJohan Hovold
Two framebuffer device-node names were looked up during probe, but were only used as flags to indicate the presence of two framebuffer device. Drop the unused framebuffer name along with a likewise unused device pointer from the driver data, and update the platform data to pass in booleans instead of the framebuffer strings. This allows us do drop the node references acquired during probe, which would otherwise leak. Note that there are no other in-kernel users of the modified platform-data fields.

2018-06-10net: phy: dp83822: use BMCR_ANENABLE instead of BMSR_ANEGCAPABLE for DP83620Alvaro Gamez Machado
DP83620 register set is compatible with the DP83848, but it also supports 100base-FX. When the hardware is configured such as that fiber mode is enabled, autonegotiation is not possible. The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE. Instead, this bit is always set high, even if the particular hardware configuration makes it so that auto negotiation is not possible [1]. Under these circumstances, the phy subsystem keeps trying for autonegotiation to happen, without success. Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on reset is set to 0 when auto negotiation is disabled, and so we use this value instead of BMSR_ANEGCAPABLE.

2018-06-10socket: close race condition between sock_close() and sockfs_setattr()Cong Wang
fchownat() doesn't even hold refcnt of fd until it figures out fd is really needed (otherwise is ignored) and releases it after it resolves the path. This means sock_close() could race with sockfs_setattr(), which leads to a NULL pointer dereference since typically we set sock->sk to NULL in ->release(). As pointed out by Al, this is unique to sockfs. So we can fix this in socket layer by acquiring inode_lock in sock_close() and checking against NULL in sockfs_setattr(). sock_release() is called in many places, only the sock_close() path matters here. And fortunately, this should not affect normal sock_close() as it is only called when the last fd refcnt is gone. It only affects sock_close() with a parallel sockfs_setattr() in progress, which is not common. Fixes: 86741ec25462 ("net: core: Add a UID field to struct sock.")

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 updates and fixes from Thomas Gleixner: - Fix the (late) fallout from the vector management rework causing hlist corruption and irq descriptor reference leaks caused by a missing sanity check. The straight forward fix triggered another long standing issue to surface. The pre rework code hid the issue due to being way slower, but now the chance that user space sees an EBUSY error return when updating irq affinities is way higher, though quite a bunch of userspace tools do not handle it properly despite the fact that EBUSY could be returned for at least 10 years. It turned out that the EBUSY return can be avoided completely by utilizing the existing delayed affinity update mechanism for irq remapped scenarios as well. That's a bit more error handling in the kernel, but avoids fruitless fingerpointing discussions with tool developers. - Decouple PHYSICAL_MASK from AMD SME as its going to be required for the upcoming Intel memory encryption support as well. - Handle legacy device ACPI detection properly for newer platforms - Fix the wrong argument ordering in the vector allocation tracepoint - Simplify the IDT setup code for the APIC=n case - Use the proper string helpers in the MTRR code - Remove a stale unused VDSO source file - Convert the microcode update lock to a raw spinlock as its used in atomic context. * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/intel_rdt: Enable CMT and MBM on new Skylake stepping x86/apic/vector: Print APIC control bits in debugfs genirq/affinity: Defer affinity setting if irq chip is busy x86/platform/uv: Use apic_ack_irq() x86/ioapic: Use apic_ack_irq() irq_remapping: Use apic_ack_irq() x86/apic: Provide apic_ack_irq() genirq/migration: Avoid out of line call if pending is not set genirq/generic_pending: Do not lose pending affinity update x86/apic/vector: Prevent hlist corruption and leaks x86/vector: Fix the args of vector_alloc tracepoint x86/idt: Simplify the idt_setup_apic_and_irq_gates() x86/platform/uv: Remove extra parentheses x86/mm: Decouple dynamic __PHYSICAL_MASK from AMD SME x86: Mark native_set_p4d() as __always_inline x86/microcode: Make the late update update_lock a raw lock for RT x86/mtrr: Convert to use strncpy_from_user() helper x86/mtrr: Convert to use match_string() helper x86/vdso: Remove unused file x86/i8237: Register device based on FADT legacy boot flag

2018-06-10signal: Remove no longer required irqsave/restoreAnna-Maria Gleixner
Commit a841796f11c9 ("signal: align __lock_task_sighand() irq disabling and RCU") introduced a rcu read side critical section with interrupts disabled. The changelog suggested that a better long-term fix would be "to make rt_mutex_unlock() disable irqs when acquiring the rt_mutex structure's ->wait_lock". This long-term fix has been made in commit b4abf91047cf ("rtmutex: Make wait_lock irq safe") for a different reason. Therefore revert commit a841796f11c9 ("signal: align > __lock_task_sighand() irq disabling and RCU") as the interrupt disable dance is not longer required. The change was tested on the base of b4abf91047cf ("rtmutex: Make wait_lock irq safe") with a four hour run of rcutorture scenario TREE03 with lockdep enabled as suggested by Paul McKenney.

2018-06-09Merge branch 'proc-cmdline'Linus Torvalds
Merge proc_cmdline simplifications. This re-writes the get_mm_cmdline() logic to be rather simpler than it used to be, and makes the semantics for "cmdline goes past the end of the original area" more natural. You _can_ use prctl(PR_SET_MM) to just point your command line somewhere else entirely, but the traditional model is to just edit things in place and that still needs to continue to work. At least this way the code makes some sense. * proc-cmdline: fs/proc: simplify and clarify get_mm_cmdline() function fs/proc: re-factor proc_pid_cmdline_read() a bit

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This time we have a good set of changes to the core framework that do some general cleanups, but nothing too major. The majority of the diff goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for Actions Semi so it takes up some lines to add all the different types, and the Qualcomm diff is there because we add support for two SoCs and it's quite a bit of data. Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And then the long tail of driver updates for various fixes and stuff follows after that. Core: - debugfs cleanups removing error checking and an unused provider API - Removal of a clk init typedef that isn't used - Usage of match_string() to simplify parent string name matching - OF clk helpers moved to their own file (linux/of_clk.h) - Make clk warnings more readable across kernel versions New Drivers: - Qualcomm SDM845 GCC and Video clk controllers - Qualcomm MSM8998 GCC - Actions Semi S900 SoC support - Nuvoton npcm750 microcontroller clks - Amlogic axg AO clock controller Removed Drivers: - Deprecated Rockchip clk-gate driver Updates: - debugfs functions stopped checking return values - Support for the MSIOF module clocks on Rensas R-Car M3-N - Support for the new Rensas RZ/G1C and R-Car E3 SoCs - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs - Berlin and Amlogic SPDX tagging - Usage of of_clk_get_parent_count() in more places - Proper implementation of the CDEV1/2 clocks on Tegra20 - Allwinner H6 PRCM clock support and R40 EMAC support - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet - Round closest support for meson's mpll driver - Support for meson8b nand clocks and gxbb video decoder clocks - Mediatek mali clks - STM32MP1 fixes - Uniphier LD11/LD20 stream demux system clock" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) clk: qcom: Export clk_fabia_pll_configure() clk: bcm: Update and add Stingray clock entries dt-bindings: clk: Update Stingray binding doc clk-si544: Properly round requested frequency to nearest match clk: ingenic: jz4770: Add 150us delay after enabling VPU clock clk: ingenic: jz4770: Enable power of AHB1 bus after ungating VPU clock clk: ingenic: jz4770: Modify C1CLK clock to disable CPU clock stop on idle clk: ingenic: jz4770: Change OTG from custom to standard gated clock clk: ingenic: Support specifying "wait for clock stable" delay clk: ingenic: Add support for clocks whose gate bit is inverted clk: use match_string() helper clk: bcm2835: use match_string() helper clk: Return void from debug_init op clk: remove clk_debugfs_add_file() clk: tegra: no need to check return value of debugfs_create functions clk: davinci: no need to check return value of debugfs_create functions clk: bcm2835: no need to check return value of debugfs_create functions clk: no need to check return value of debugfs_create functions clk: imx6: add EPIT clock support clk: mvebu: use correct bit for 98DX3236 NAND ...
