2018-06-12IB/uverbs: Fix ordering of ucontext check in ib_uverbs_writeJason Gunthorpe
During disassociation the ucontext will become NULL, however due to how the SRCU locking works the ucontext must only be examined after looking at the ib_dev, which governs the RCU control flow. With the wrong ordering userspace will see EINVAL instead of EIO for a disassociated uverbs FD, which breaks rdma-core. Cc: stable@vger.kernel.org Fixes: 491d5c6a3023 ("RDMA/uverbs: Move uncontext check before SRCU read lock") Reported-by: Mark Bloch <markb@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Reviewed-by: Leon Romanovsky <leonro@mellanox.com>

2018-06-12netfilter: nf_tables: fix module unload raceFlorian Westphal
We must first remove the nfnetlink protocol handler when nf_tables module is unloaded -- we don't want userspace to submit new change requests once we've started to tear down nft state. Furthermore, nfnetlink must not call any subsystem function after call_batch returned -EAGAIN. EAGAIN means the subsys mutex was dropped, so its unlikely but possible that nf_tables subsystem was removed due to 'rmmod nf_tables' on another cpu. Therefore, we must abort batch completely and not move on to next part of the batch. Last, we can't invoke ->abort unless we've checked that the subsystem is still registered. Change netns exit path of nf_tables to make sure any incompleted transaction gets removed on exit.

2018-06-12kvm: x86: use correct privilege level for sgdt/sidt/fxsave/fxrstor accessPaolo Bonzini
The functions that were used in the emulation of fxrstor, fxsave, sgdt and sidt were originally meant for task switching, and as such they did not check privilege levels. This is very bad when the same functions are used in the emulation of unprivileged instructions. This is CVE-2018-10853. The obvious fix is to add a new argument to ops->read_std and ops->write_std, which decides whether the access is a "system" access or should use the processor's CPL.

Int the next patch the emulator's .read_std and .write_std callbacks will grow another argument, which is not needed in kvm_read_guest_virt and kvm_write_guest_virt_system's callers. Since we have to make separate functions, let's give the currently existing names a nicer interface, too.

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.

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.

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 ...

Updated to use CONFIG_XFRM_OFFLOAD instead of CONFIG_XFRM, since the code requires CONFIG_XFRM_OFFLOAD to be enabled. Moved the IPsec initialization function to be more consistent with the placement of similar initialization functions and before the call to reset the hardware, which will clean up any link issues that may have been introduced. Fixed the boolean logic that was testing for transmit OR receive ready bits, when it should have been testing for transmit AND receive ready bits. Fixed the bit definitions for SECTXSTAT and SECRXSTAT registers and ensure that if IPsec is disabled on the part, do not enable it. ==================== Signed-off-by: David S.
