2023-11-16T12:59:31Z

T200 card variants use the XC7A200T FPGA instead of XC7A100T. The SPI FLASH memory layout is different as the FPGA requires bigger FW images. Signed-off-by: Martin Tůma Signed-off-by: Hans Verkuil

media: vsp1: Remove unbalanced .s_stream(0) calls

2023-11-13T01:40:13Z

The VSP1 driver uses the subdev .s_stream() operation to stop WPF instances, without a corresponding call to start them. The V4L2 subdev core started warning about unbalanced .s_stream() calls in commit 009905ec5043 ("media: v4l2-subdev: Document and enforce .s_stream() requirements"), causing a regression with this driver. Fix the problem by replacing the .s_stream() operation with an explicit function call for WPF instances. This allows sharing an additional data structure between RPF and WPF instances.

Pull media updates from Mauro Carvalho Chehab: - the old V4L2 core videobuf kAPI was finally removed. All media drivers should now be using VB2 kAPI - new automotive driver: mgb4 - new platform video driver: npcm-video - new sensor driver: mt9m114 - new TI driver used in conjunction with Cadence CSI2RX IP to bridge TI-specific parts - ir-rx51 was removed and the N900 DT binding was moved to the pwm-ir-tx generic driver - drop atomisp-specific ov5693, using the upstream driver instead - the camss driver has gained RDI3 support for VFE 17x - the atomisp driver now detects ISP2400 or ISP2401 at run time. No need to set it up at build time anymore - lots of driver fixes, cleanups and improvements * tag 'media/v6.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (377 commits) media: nuvoton: VIDEO_NPCM_VCD_ECE should depend on ARCH_NPCM media: venus: Fix firmware path for resources media: venus: hfi_cmds: Replace one-element array with flex-array member and use __counted_by media: venus: hfi_parser: Add check to keep the number of codecs within range media: venus: hfi: add checks to handle capabilities from firmware media: venus: hfi: fix the check to handle session buffer requirement media: venus: hfi: add checks to perform sanity on queue pointers media: platform: cadence: select MIPI_DPHY dependency media: MAINTAINERS: Fix path for J721E CSI2RX bindings media: cec: meson: always include meson sub-directory in Makefile media: videobuf2: Fix IS_ERR checking in vb2_dc_put_userptr() media: platform: mtk-mdp3: fix uninitialized variable in mdp_path_config() media: mediatek: vcodec: using encoder device to alloc/free encoder memory media: imx-jpeg: notify source chagne event when the first picture parsed media: cx231xx: Use EP5_BUF_SIZE macro media: siano: Drop unnecessary error check for debugfs_create_dir/file() media: mediatek: vcodec: Handle invalid encoder vsi media: aspeed: Drop unnecessary error check for debugfs_create_file() Documentation: media: buffer.rst: fix V4L2_BUF_FLAG_PREPARED Documentation: media: gen-errors.rst: fix confusing ENOTTY description ...

The Nuvoton NPCM Video Capture/Differentiation Engine (VCD) and Encoding Compression Engine (ECE) are only present on Nuvoton NPCM SoCs. Hence add a dependency on ARCH_NPCM, to prevent asking the user about these drivers when configuring a kernel without Nuvoton NPCM Architecture support.

media: venus: hfi_cmds: Replace one-element array with flex-array member and use __counted_by

2023-10-23T10:24:52Z

Array `data` in `struct hfi_sfr` is being used as a fake flexible array at run-time: drivers/media/platform/qcom/venus/hfi_venus.c: 1033 p = memchr(sfr->data, '\0', sfr->buf_size); 1034 /* 1035 * SFR isn't guaranteed to be NULL terminated since SYS_ERROR indicates 1036 * that Venus is in the process of crashing. 1037 */ 1038 if (!p) 1039 sfr->data[sfr->buf_size - 1] = '\0'; 1040 1041 dev_err_ratelimited(dev, "SFR message from FW: %s\n", sfr->data); Fake flexible arrays are deprecated, and should be replaced by flexible-array members. So, replace one-element array with a flexible-array member in `struct hfi_sfr`. While there, also annotate array `data` with __counted_by() to prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). This results in no differences in binary output. This issue was found with the help of Coccinelle, and audited and fixed manually. Signed-off-by: Gustavo A. R.

media: venus: hfi_parser: Add check to keep the number of codecs within range

2023-10-23T10:24:52Z

Supported codec bitmask is populated from the payload from venus firmware. There is a possible case when all the bits in the codec bitmask is set. In such case, core cap for decoder is filled and MAX_CODEC_NUM is utilized. Now while filling the caps for encoder, it can lead to access the caps array beyong 32 index. Hence leading to OOB write. The fix counts the supported encoder and decoder. If the count is more than max, then it skips accessing the caps.
