treewide: Use array_size in f2fs_kvzalloc()
The f2fs_kvzalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: f2fs_kvzalloc(handle, a * b, gfp) with: f2fs_kvzalloc(handle, array_size(a, b), gfp) as well as handling cases of: f2fs_kvzalloc(handle, a * b * c, gfp) with: f2fs_kvzalloc(handle, array3_size(a, b, c), gfp) This does, however, attempt to ignore constant size factors like: f2fs_kvzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.

treewide: Use array_size() in sock_kmalloc()
The sock_kmalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: sock_kmalloc(handle, a * b, gfp) with: sock_kmalloc(handle, array_size(a, b), gfp) as well as handling cases of: sock_kmalloc(handle, a * b * c, gfp) with: sock_kmalloc(handle, array3_size(a, b, c), gfp) This does, however, attempt to ignore constant size factors like: sock_kmalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion.

treewide: kmalloc() -> kmalloc_array()
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

UBIFS: Fix potential integer overflow in allocation
There is potential for the size and len fields in ubifs_data_node to be
too large causing either a negative value for the length fields or an
integer overflow leading to an incorrect memory allocation. Likewise,
when the len field is small, an integer underflow may occur.

kvm: x86: use correct privilege level for sgdt/sidt/fxsave/fxrstor access
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.

KVM: x86: pass kvm_vcpu to kvm_read_guest_virt and kvm_write_guest_virt_system
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.

skip LAYOUTRETURN if layout is invalid
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.

ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window.

ARM: Device-tree updates
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 -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfBtUPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3wfYQAI1hlPhRx7H1zbc59zdlW6daY7y1+dXuqoCs K5Hxsurlsbnx9fjeGcBp/razL5YtdZmBYII8IBhKzhLKp/A0gqmX7W9pTNQj9/Sp SOIl8dci/yr0HUpgwc4IdVhJBdpplv48GK3q8opSocI/J9dnD873NHLlvTpCB+Jy GCD9tB56JnOfTO+n0Yg+tyuig1jIQCc52Iwnmxv2vYPbsHUaEmqz1Z+wBe0BaDk+ eVsohNQI/2xxRzv8PE13H/ojcZ532rF45aw6ypRwCvg1MzCYXSdKLJlIWx8Ci581 YmRPlCOWai+AxSATgJhIR9n9dxn6hqxEgVyu7AOxPVa0O4DKB3oy8PPo5wlOCKcU J1n5zJwnULWw4eVa1ag/cEMbz95QMC1F9MmyiLUfz3esHwyD/Gl3ks9v1gwn9XYp xsI+oGnMy/Uz4oZ1/XM5CO5UUDXyixVD3pYEF8wLaYX2JY8zETI5qfvNL0bwZX3P lLFCI7Xdwsk3+HCp7aHs4KkWHLVGq65SxrXKTIpU+vEq+0RYiV/cWP9Swa/RNrMH gB00oZ2TBRuIr/KxsCKyCkKApocW4J4WtZ2sMY7QDXzW68lq8oIbefY+6Abgk4/7 6J7D5n0gmTB38wrzZCY5UF0eQrLjPwnxuLywEll5oLFbNTr/7Aruk2kFYEMGjM9E QmXGoHXU =jLvk -----END PGP SIGNATURE----- Merge tag 'armsoc-dt' of 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.

ARM: SoC platform updates
Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms. The branch also contains defconfig updates to turn on drivers and options as needed on the various platforms. The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D). Linus Walleij is also removing support for ux500 (Sony Ericsson) U8540/9540 SoCs that never made it to significant mass production and products. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCGIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3Ks8P/3j87Za+6OTCzo+lW2byUy1CI4muGwxNSIxX 65A1Wt2qvRDxjCX4MI5Cx8P1YdYJv+5ZF2p4vdlgQXoz3/XDbG+lxJ+/lyWl/+MK 9kGsQWwEVicbGkaJCYR4ZKvfAwZ9jf7+cndY0Vgii44xQLsQZHEIfIO+mdlK43GZ xqaSckLQQzsDqjMUIckiyVy97RsDk1eLK+H2I+l7qs9v0z5UnhoD2CTxX5LzT8eH NlFmfUPN7Znshmt0aMznZyBRr2oM5Dsg49SfG0WhbOzyiZjSpw8MQ0N+RzyROhhB h5PjyuZN9fx2dO8Jjkqt3B8KmGFNDarGOmrasIJeCJDFRa9NStqFn0y4qJXS2wU7 4La3GoBYRV8x0gq339pQ+70qKuD06e62GL7kV656yi+93CitWxy6IjrIACjSX6zH PD1hQpewfXAcHAHdBqNevRcz/sjG+36GJSCgI4umSP48NMlCuZafFAT4U/PVlt4E 6VRQDeoi5ZFYIuPL1+bZvHax4fFxJGnaf02uQ/OPYP1o48AueSSvdo6bUPFbhwOD u0/uo3r+HxtQsw9I3tP3kj3/775BJclkO6zbG/dGZ8obuzuDwhuFtr3rzCrP/IzN n3rcBuFNZE6SQeKU+Tvmnh8ZLhJc5L8EYvqmihZj+BSfprBc8POFR2la4MRnHSn+ tPEC/n9E =S5wc -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Olof Johansson: "Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms.
