media: mediatek: vcodec: bound AV1 tile-start copy to the array capacity

2026-09-07T07:01:05+00:00

vdec_av1_slice_setup_tile() copies tile_cols + 1 / tile_rows + 1 entries into mi_col_starts[] / mi_row_starts[] from the bitstream tile_info. Bound the copy to the array capacity.

media: verisilicon: rockchip: reject AV1 frames exceeding the tile capacity

2026-09-07T07:01:05+00:00

rockchip_vpu981_av1_dec_set_tile_info() indexes the tile group entry array by tile1 * tile_cols + tile0, reading up to tile_cols * tile_rows entries, lays out one descriptor per tile in the AV1_MAX_TILES tile_info buffer, and programs the real tile_cols / tile_rows into the hardware. The tile group entry control is a dynamic array sized to the number of entries userspace submitted, independent of tile_cols / tile_rows, so a frame that claims more tiles than entries reads past the array. A frame that claims more than AV1_MAX_TILES tiles also leaves the hardware programmed for more tiles than the descriptor buffer holds. Reject both in prepare_run(): tile_cols * tile_rows must not exceed the submitted entry count or AV1_MAX_TILES. The entry count is read via v4l2_ctrl_find() (ctrl->elems). This mirrors the bound the mediatek AV1 decoder already enforces.

media: verisilicon: rockchip: guard VPU981 AV1 divisor and tile buffer

2026-09-07T07:01:05+00:00

rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by tile_info->tile_cols and writes one descriptor per tile into the tile_info DMA buffer, which holds AV1_MAX_TILES entries; tile_cols and tile_rows come from the bitstream. Guard the division against a zero tile_cols by initialising the context-update values to zero and computing them only when tile_cols is non-zero, and stop the descriptor writes once the tile_info buffer is full. The tile geometry written to the hardware registers is left unmodified; the per-dimension and total tile bounds are enforced by the control validation.

media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity

2026-09-07T07:01:05+00:00

prepare_tile_info_buffer() writes one entry per tile into the tile_sizes DMA buffer, sized for a grid equal to the PPS uAPI array capacity. Use the bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows() helpers so the loops stay inside the buffer.

media: rkvdec: bound HEVC tile loops and PPS id to the array capacity

2026-09-07T07:01:05+00:00

compute_tiles_uniform() and compute_tiles_non_uniform() loop over num_tile_columns_minus1 + 1 / num_tile_rows_minus1 + 1 entries, and assemble_hw_pps() writes one COLUMN_WIDTH / ROW_HEIGHT register per tile and indexes priv_tbl->param_set[] by pic_parameter_set_id, all taken from the untrusted PPS. Use the bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows() helpers for the tile loops, and bail out of assemble_hw_pps() before indexing priv_tbl->param_set[] with an out-of-range pic_parameter_set_id, so the writes stay within the hardware tables.

treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

media: rppx1: bls: read the raw pattern from the PRE2 acquisition module

2026-08-31T06:57:06+00:00

rppx1_bls_swap_regs() gets the Bayer pattern from the acquisition module. The PRE1 path uses pre1.acq, but the PRE2 path mistakenly uses pre2.bls. The BLS module does not store a Bayer pattern, so PRE2 would read zero (RGGB) and map fixed black levels to the wrong colour registers. PRE2 is not started or dispatched yet, so the bug is currently latent. Read the pattern from pre2.acq, as the PRE1 path does, so that enabling PRE2 does not start out with the wrong register mapping.

media: rppx1: describe the MAIN_POST white balance gains block

2026-08-31T06:57:06+00:00

rppx1_ext_params_blocks_info[] is indexed by block type and is built with designated initialisers, so a block type without an entry is left as a zero-sized hole. RPPX1_PARAMS_BLOCK_TYPE_AWBG_POST is the only such hole: a block reporting that type and a size of zero passes v4l2_isp_params_validate_buffer(), which then has nothing to advance the walk with. Describe the block, so the array covers all block types the uAPI defines. The MAIN_POST white balance gains module is probed and started with the rest of the POST pipe, and RPPX1_PARAMS_MAX_SIZE already reserves room for all three white balance gains blocks. The block is not dispatched by rppx1_params(), in line with the other described blocks that have no users yet.
