2021-11-17staging: most: dim2: do not double-register the same deviceNikita Yushchenko
[ Upstream commit 2ab189164056b05474275bb40caa038a37713061 ] Commit 723de0f9171e ("staging: most: remove device from interface structure") moved registration of driver-provided struct device to the most subsystem. Dim2 used to register the same struct device to provide a custom device attribute. This causes double-registration of the same struct device. Fix that by moving the custom attribute to driver's dev_groups. This moves attribute to the platform_device object, which is a better location for platform-specific attributes anyway.

2021-11-17media: rkvdec: Support dynamic resolution changesChen-Yu Tsai
commit 0887e9e152efbd3601d6c907e90033d25067277d upstream. The mem-to-mem stateless decoder API specifies support for dynamic resolution changes. In particular, the decoder should accept format changes on the OUTPUT queue even when buffers have been allocated, as long as it is not streaming. Relax restrictions for S_FMT as described in the previous paragraph, and as long as the codec format remains the same. This aligns it with the Hantro and Cedrus decoders. This change was mostly based on commit ae02d49493b5 ("media: hantro: Fix s_fmt for dynamic resolution changes"). Since rkvdec_s_fmt() is now just a wrapper around the output/capture variants without any additional shared functionality, drop the wrapper and call the respective functions directly.

2021-11-17media: rkvdec: Do not override sizeimage for output formatChen-Yu Tsai
commit 298d8e8f7bcf023aceb60232d59b983255fec0df upstream. The rkvdec H.264 decoder currently overrides sizeimage for the output format. This causes issues when userspace requires and requests a larger buffer, but ends up with one of insufficient size. Instead, only provide a default size if none was requested. This fixes the video_decode_accelerator_tests from Chromium failing on the first frame due to insufficient buffer space. It also aligns the behavior of the rkvdec driver with the Hantro and Cedrus drivers.

2021-11-12media: staging/intel-ipu3: css: Fix wrong size comparison imgu_css_fw_initGustavo A. R. Silva
commit a44f9d6f9dc1fb314a3f1ed2dcd4fbbcc3d9f892 upstream. There is a wrong comparison of the total size of the loaded firmware css->fw->size with the size of a pointer to struct imgu_fw_header. Turn binary_header into a flexible-array member[1][2], use the struct_size() helper and fix the wrong size comparison. Notice that the loaded firmware needs to contain at least one 'struct imgu_fw_info' item in the binary_header[] array. It's also worth mentioning that "css->fw->size < struct_size(css->fwp, binary_header, 1)" with binary_header declared as a flexible-array member is equivalent to "css->fw->size < sizeof(struct imgu_fw_header)" with binary_header declared as a one-element array (as in the original code). The replacement of the one-element array with a flexible-array member also helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

commit c052cc1a069c3e575619cf64ec427eb41176ca70 upstream. Syzbot reported use-after-free in rtl8712_dl_fw(). The problem was in race condition between r871xu_dev_remove() ->ndo_open() callback.

2021-08-23Revert "media: dvb header files: move some headers to staging"Linus Torvalds
This reverts commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177. It turns out that some user-space applications use these uapi header files, so even though the only user of the interface is an old driver that was moved to staging, moving the header files causes unnecessary pain. Generally, we really don't want user space to use kernel headers directly (exactly because it causes pain when we re-organize), and instead copy them as needed. But these things happen, and the headers were in the uapi directory, so I guess it's not entirely unreasonable.

2021-07-27staging: rtl8712: error handling refactoringPavel Skripkin
There was strange error handling logic in case of fw load failure. For some reason fw loader callback was doing clean up stuff when fw is not available. I don't see any reason behind doing this. Since this driver doesn't have EEPROM firmware let's just disconnect it in case of fw load failure. Doing clean up stuff in 2 different place which can run concurently is not good idea and syzbot found 2 bugs related to this strange approach. So, in this pacth I deleted all clean up code from fw callback and made a call to device_release_driver() under device_lock(parent) in case of fw load failure. This approach is more generic and it defend driver from UAF bugs, since all clean up code is moved to one place.

This patch is preparation for following patch for error handling refactoring. flush_scheduled_work() takes (wq_completion)events lock and it can lead to deadlock when r871xu_dev_remove() is called from workqueue. To avoid deadlock sutiation we can change flush_scheduled_work() call to flush_work() call for all possibly scheduled works in this driver, since next patch adds device_release_driver() in case of fw load failure.

Honestly though that's just a bunch of data so the diffstat reflects that. Looking beyond that there's just a bunch of updates all around in various clk drivers.

Overall the driver changes look to be mostly enabling more clks and non-critical fixes that we could hold until the next merge window. I'm especially excited about the series from Arnd that graduates clkdev to be the only implementation of clk_get() and clk_put(). That's a good step in the right direction to migreate eveerything over to the common clk framework. Now we don't have to worry about clkdev specific details, they're just part of the clk API now. Core: - clkdev is now the only option, i.e. clk_get()/clk_put() is implemented in only one place in the kernel instead of in drivers/clk/clkdev.c and in architectures that want their own implementation New Drivers: - Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant Clock Jitter Cleaner With Dual Loop PLLs - Qualcomm MDM9607 GCC - Qualcomm SC8180X display clks - Qualcomm SM6125 GCC - Qualcomm SM8250 CAMCC (camera) - Renesas RZ/G2L SoC - Hisilicon hi3559A SoC Updates: - Stop using clock-output-names in ST clk drivers (yay!) - Support secure mode of STM32MP1 SoCs - Improve clock support for Actions S500 SoC - duty cycle setting support on qcom clks - Add TI am33xx spread spectrum clock support - Use determine_rate() for the Amlogic pll ops instead of round_rate() - Restrict Amlogic gp0/1 and audio plls range on g12a/sm1 - Improve Amlogic axg-audio controller error on deferral - Add NNA clocks on Amlogic g12a - Reduce memory footprint of Rockchip PLL rate tables - A fix for the newly added Rockchip rk3568 clk driver - Exported clock for the newly added Rockchip video decoder - Remove audio ipg clock from i.MX8MP - Remove deprecated legacy clock binding for i.MX SCU clock driver - Use common clk-imx8qxp for both i.MX8QXP and i.MX8QM - Add multiple clocks to clk-imx8qxp driver (enet, hdmi, lcdif, audio, parallel interface) - Add dedicated clock ops for i.MX paralel interface - Different fixes for clocks controlled by ATF on i.MX SoCs - Add A53/A72 frequency scaling support i.MX clk-scu driver - Add special case for DCSS clock on suspend for i.MX clk-scu driver - Add parent save/restore on suspend/resume to i.MX clk-scu driver - Skip runtime PM enablement for CPU clocks in i.MX clk-scu driver - Remove the sys1_pll/sys2_pll clock gates for i.MX8MQ and their bindings - Tegra clk driver no longer deasserts resets on clk_enable as it gets in the way of certain power-up sequences - Fix compile testing for Tegra clk driver - One patch to fix a divider on the Allwinner v3s Audio PLL - Add support for CPU core clock boost modes on Renesas R-Car Gen3 - Add ISPCS (Image Signal Processor) clocks on Renesas R-Car V3U - Switch SH/R-Mobile and R-Car "DIV6" clocks to .determine_rate() and improve support for multiple parents - Switch Renesas RZ/N1 divider clocks to .determine_rate() - Add ZA2 (Audio Clock Generator) clock on Renesas R-Car D3 - Convert ar7 to common clk framework - Convert ralink to common clk framework" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (161 commits) clk: zynqmp: Handle divider specific read only flag clk: zynqmp: Use firmware specific mux clock flags clk: zynqmp: Use firmware specific divider clock flags clk: zynqmp: Use firmware specific common clock flags clk: lmk04832: Use of match table clk: lmk04832: Depend on SPI clk: stm32mp1: new compatible for secure RCC support dt-bindings: clock: stm32mp1 new compatible for secure rcc dt-bindings: reset: add MCU HOLD BOOT ID for SCMI reset domains on stm32mp15 dt-bindings: reset: add IDs for SCMI reset domains on stm32mp15 dt-bindings: clock: add IDs for SCMI clocks on stm32mp15 reset: stm32mp1: remove stm32mp1 reset clk: hisilicon: Add clock driver for hi3559A SoC dt-bindings: Document the hi3559a clock bindings clk: si5341: Add sysfs properties to allow checking/resetting device faults clk: si5341: Add silabs,iovdd-33 property clk: si5341: Add silabs,xaxb-ext-clk property clk: si5341: Allow different output VDD_SEL values clk: si5341: Update initialization magic clk: si5341: Check for input clock presence and PLL lock on startup ...
2021-07-01kernel.h: split out panic and oops helpersAndy Shevchenko
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.
