2019-07-18Merge branch 'floppy'Linus Torvalds
Merge floppy ioctl verification fixes from Denis Efremov. This also marks the floppy driver as orphaned - it turns out that Jiri no longer has working hardware. Actual working physical floppy hardware is getting hard to find, and while Willy was able to test this, I think the driver can be considered pretty much dead from an actual hardware standpoint. The hardware that is still sold seems to be mainly USB-based, which doesn't use this legacy driver at all. The old floppy disk controller is still emulated in various VM environments, so the driver isn't going away, but let's see if anybody is interested to step up to maintain it. The lack of hardware also likely means that the ioctl range verification fixes are probably mostly relevant to anybody using floppies in a virtual environment. Which is probably also going away in favor of USB storage emulation, but who knows. Will Decon reviewed the patches but I'm not rebasing them just for that, so I'll add a Reviewed-by: Will Deacon <will@kernel.org> here instead. * floppy: MAINTAINERS: mark floppy.c orphaned floppy: fix out-of-bounds read in copy_buffer floppy: fix invalid pointer dereference in drive_name floppy: fix out-of-bounds read in next_valid_format floppy: fix div-by-zero in setup_format_params

I volunteered myself to maintain it quite some time ago back when I fixed the concurrency issues which exhibited itself only with VM-emulated devices, and at the same time I still had the physical 3.5" reader to test all the changes. The reader doesn't work any more though, so I guess it's time to step down from this super-prestigious role :p and mark floppy.c as Orphaned.

2019-07-18riscv: fix build break after macro-to-function conversion in generic ↵Paul Walmsley
cacheflush.h Commit c296d4dc13ae ("asm-generic: fix a compilation warning") converted the various flush_*cache_* macros in asm-generic/cacheflush.h to static inline functions. This breaks RISC-V builds, since RISC-V's cacheflush.h includes the generic cacheflush.h and then undefines the macros to be overridden. Fix by copying the subset of the no-op functions that are reused from the generic cacheflush.h into the RISC-V cacheflush.h, and dropping the include of the generic cacheflush.h.

2019-07-17floppy: fix out-of-bounds read in copy_bufferDenis Efremov
This fixes a global out-of-bounds read access in the copy_buffer function of the floppy driver. The FDDEFPRM ioctl allows one to set the geometry of a disk. The sect and head fields (unsigned int) of the floppy_drive structure are used to compute the max_sector (int) in the make_raw_rw_request function. It is possible to overflow the max_sector. Next, max_sector is passed to the copy_buffer function and used in one of the memcpy calls. An unprivileged user could trigger the bug if the device is accessible, but requires a floppy disk to be inserted. The patch adds the check for the .sect * .head multiplication for not overflowing in the set_geometry function. The bug was found by syzkaller.

2019-07-17floppy: fix invalid pointer dereference in drive_nameDenis Efremov
This fixes the invalid pointer dereference in the drive_name function of the floppy driver. The native_format field of the struct floppy_drive_params is used as floppy_type array index in the drive_name function. Thus, the field should be checked the same way as the autodetect field. To trigger the bug, one could use a value out of range and set the drive parameters with the FDSETDRVPRM ioctl. Next, FDGETDRVTYP ioctl should be used to call the drive_name. A floppy disk is not required to be inserted. CAP_SYS_ADMIN is required to call FDSETDRVPRM. The patch adds the check for a value of the native_format field to be in the '0 <= x < ARRAY_SIZE(floppy_type)' range of the floppy_type array indices. The bug was found by syzkaller.

This fixes a global out-of-bounds read access in the next_valid_format function of the floppy driver. The values from autodetect field of the struct floppy_drive_params are used as indices for the floppy_type array in the next_valid_format function 'floppy_type[DP->autodetect[probed_format]].sect'.

2019-07-17floppy: fix div-by-zero in setup_format_paramsDenis Efremov
This fixes a divide by zero error in the setup_format_params function of the floppy driver. Two consecutive ioctls can trigger the bug: The first one should set the drive geometry with such .sect and .rate values for the F_SECT_PER_TRACK to become zero. Next, the floppy format operation should be called. A floppy disk is not required to be inserted. An unprivileged user could trigger the bug if the device is accessible. The patch checks F_SECT_PER_TRACK for a non-zero value in the set_geometry function. The proper check should involve a reasonable upper limit for the .sect and .rate fields, but it could change the UAPI. The patch also checks F_SECT_PER_TRACK in the setup_format_params, and cancels the formatting operation in case of zero. The bug was found by syzkaller.

2019-07-17parisc: Ensure userspace privilege for ptraced processes in regset functionsHelge Deller
On parisc the privilege level of a process is stored in the lowest two bits of the instruction pointers (IAOQ0 and IAOQ1). On Linux we use privilege level 0 for the kernel and privilege level 3 for user-space. So userspace should not be allowed to modify IAOQ0 or IAOQ1 of a ptraced process to change it's privilege level to e.g. 0 to try to gain kernel privileges. This patch prevents such modifications in the regset support functions by always setting the two lowest bits to one (which relates to privilege level 3 for user-space) if IAOQ0 or IAOQ1 are modified via ptrace regset calls.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features. Core: - Add a 'clk_parent' file in clk debugfs - Add a clk_bulk_get_optional() API (with devm too) New Drivers: - Support gated clk controller on MIPS based BCM63XX SoCs - Support SiLabs Si5341 and Si5340 chips - Support for CPU clks on Raspberry Pi devices - Audsys clock driver for MediaTek MT8516 SoCs Updates: - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme - Small frequency support for SiLabs Si544 chips - Slow clk support for AT91 SAM9X60 SoCs - Remove dead code in various clk drivers (-Wunused) - Support for Marvell 98DX1135 SoCs - Get duty cycle of generic pwm clks - Improvement in mmc phase calculation and cleanup of some rate defintions - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs - Add GPIO, SNVS and GIC clocks for i.MX8 drivers - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting - Add clks for new Exynos5422 Dynamic Memory Controller driver - Clock definition for Exynos4412 Mali - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3 - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs - TI clock probing done from DT by default instead of firmware - Fix Amlogic Meson mpll fractional part and spread sprectrum issues - Add Amlogic meson8 audio clocks - Add Amlogic g12a temperature sensors clocks - Add Amlogic g12a and g12b cpu clocks - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W - Add Clock Domain support on Renesas RZ/N1" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (190 commits) clk: consoldiate the __clk_get_hw() declarations clk: sprd: Add check for return value of sprd_clk_regmap_init() clk: lochnagar: Update DT binding doc to include the primary SPDIF MCLK clk: Add Si5341/Si5340 driver dt-bindings: clock: Add silabs,si5341 clk: clk-si544: Implement small frequency change support clk: add BCM63XX gated clock controller driver devicetree: document the BCM63XX gated clock bindings clk: at91: sckc: use dedicated functions to unregister clock clk: at91: sckc: improve error path for sama5d4 sck registration clk: at91: sckc: remove unnecessary line clk: at91: sckc: improve error path for sam9x5 sck register clk: at91: sckc: add support to free slow clock osclillator clk: at91: sckc: add support to free slow rc oscillator clk: at91: sckc: add support to free slow oscillator clk: rockchip: export HDMIPHY clock on rk3228 clk: rockchip: add watchdog pclk on rk3328 clk: rockchip: add clock id for hdmi_phy special clock on rk3228 clk: rockchip: add clock id for watchdog pclk on rk3328 clk: at91: sckc: add support for SAM9X60 ...
