[PATCH v3 00/17] media: apple: add avd driver

[Sofus Forstreuter]

Hi,

This series enables hardware video decoding on Apple Silicon M1, M2 and
M3 SoCs. It adds support for all the codecs AVD (Apple Video Decoder)
supports, which is H264, H265, VP9 and AV1 (only on M3+).

The AVD is a bit unique both as a video decoder and an IP block on Apple
Silicon SoCs. Instead of following the normal "a register for each
parameter", AVD is programmed through one single register. This means
the order of the writes are important, but its also important to ensure
we dont write faster than the hardware can process. To solve this, we
use the included Cortex-M3 co-processor. The CM3 accepts unsigned code,
which we take advantage off [1].
The driver prepares the instructions and writes them into segments,
which are submitted to the CM3. The CM3 then programs the hardware and
notifies the AP when the job is done or if an error occurred.

The driver implements the V4L2 M2M stateless decoder API. The driver's
framework is based very heavy on rkvdecs driver. It therefore comes as
no suprise that `v4l2-compliance` reports no errors:
Total for avd device /dev/video0: 49, Succeeded: 49, Failed: 0, Warnings: 0

The fluster scores are:
JVT-AVC_V1: 77/135
JVT-FR-EXT: 42/69
VP9-TEST-VECTORS: 216/305
VP9-TEST-VECTORS-HIGH: 1/6
JCT-VC-HEVC_V1: 145/147
AV1-TEST-VECTORS: 238/242

Since not all unsupported H264 streams are rejected, the scores
depend on the reset working, this only works with a patch to the
apple-dart driver so that the IOMMU attach/detach trick works.

All codecs support 4:2:2, 4:2:0, in 10 and 8 bit. By default, AVD
outputs in NV12, NV16, P010 and P210. Support for 4:4:4 and 12 bit
formats has not been added yet.

Internally the AVD uses an Apple specific compressed and tiled format
called Interchange to store reference image data. This is stored after
image data across all codecs. Apple Interchange is used for sharing
buffers with other hardware blocks (GPU, display controller).
The V4L2 pixel formats have been added to help with calculating sizes.

This driver has been tested on most Apple Silicon SoCs in our downstream
tree [2]. Its expected this driver will work on M4, M5, M6 and the Neo,
with firmware already being written for all except the M6 SoCs [3].

The groundwork for this was laid many years ago by Jamie, R and Eileen,
who through a combined effort managed to reverse engineer many core
parts of the AVD block.
This driver would not have been possible without the work done by
Eileen, who wrote initial support for H264, H265, VP9 and excellent
tooling [4], allowing me to reverse engineer AV1 and make the driver
conformant.

+
+description: |
+  AVD is a stateless video decode IP block present on Apple devices.
+  Notably it includes an ARM Cortex-M3 and associated DMA controller.
+  AVD is capable of decoding H264, H265, VP9 and AV1 on newer SoCs.
+
+  The IP does not change much, with changes being mostly the CM3 having more
+  memory and interrupts.

[PATCH v3 03/17] media: v4l2: Add Apple interchange pixel formats

[Sofus Forstreuter]

Apple Interchange is a compressed and tiled format modifier.

Its intended use is for sharing buffers between hardware blocks (GPU,
display controller, video codecs) on Apple platforms.

Add it to the v4l2_format_info table to help with calculating sizes.

[PATCH v3 07/17] media: apple: avd: add h264 support

[Sofus Forstreuter]

The fluster score is 77/135 for JVT-AVC_V1 and 42/69 for JVT-FR-EXT.

While there are no unexpected test cases. FM1_FT_E, SP1_BT_A and
sp2_bt_b still have some unsupported features that are not rejected,
which causes the hardware to fault.

[PATCH v3 09/17] media: apple: avd: add hevc support

[Sofus Forstreuter]

The fluster score is 145/147 for JCT-VC-HEVC_V1.

RPS_E_qualcomm_5 is failing, but should be supported.

[PATCH v3 10/17] media: apple: avd: add av1 support

[Sofus Forstreuter]

AVD only supports decoding AV1 on newer SoCs, it does not support film
grain.

The entropymode files are adapted from
commit c0d0e579db4e ("media: verisilicon: Add AV1 entropy helpers")
with some extra tables being added and some tables being changed a bit.

The fluster score is 238/242 for AV1-TEST-VECTORS.

[Severity: High]
Does adding this check without updating std_init_compound() make the
default value of V4L2_CID_STATELESS_AV1_FRAME invalid?

Because ti->context_update_tile_id is an unsigned __u8, validate_av1_tile_info()
returns -EINVAL whenever tile_cols == 0 or tile_rows == 0.

However, std_init_compound() in drivers/media/v4l2-core/v4l2-ctrls-core.c
does not have a case for V4L2_CTRL_TYPE_AV1_FRAME, so it zero-initializes
the control with tile_cols = 0 and tile_rows = 0:

drivers/media/v4l2-core/v4l2-ctrls-core.c:std_init_compound() {
	if (ctrl->p_def.p_const)
		memcpy(p, ctrl->p_def.p_const, ctrl->elem_size);
	else
		memset(p, 0, ctrl->elem_size);

	switch ((u32)ctrl->type) {
	...
	case V4L2_CTRL_TYPE_AV1_SEQUENCE:
		p_av1_sequence = p;
		p_av1_sequence->bit_depth = 8;
		p_av1_sequence->flags |= V4L2_AV1_SEQUENCE_FLAG_SUBSAMPLING_X |
					 V4L2_AV1_SEQUENCE_FLAG_SUBSAMPLING_Y;
		break;
	...
	}
}

As a result, querying the default or initial value of
V4L2_CID_STATELESS_AV1_FRAME via VIDIOC_G_EXT_CTRLS and passing it to
VIDIOC_TRY_EXT_CTRLS or VIDIOC_S_EXT_CTRLS fails with -EINVAL in
std_validate_compound() -> validate_av1_frame() -> validate_av1_tile_info().

Furthermore, if userspace queues a request and starts streaming on a
driver such as Hantro VPU981 AV1 without setting V4L2_CID_STATELESS_AV1_FRAME
in the request, ctrl->p_cur remains at its zero-initialized state from
std_init_compound() and triggers a divide-by-zero in
rockchip_vpu981_av1_dec_set_tile_info():

drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:rockchip_vpu981_av1_dec_set_tile_info() {
	int context_update_y =
	    tile_info->context_update_tile_id / tile_info->tile_cols;
	int context_update_x =
	    tile_info->context_update_tile_id % tile_info->tile_cols;
}

Should std_init_compound() also handle V4L2_CTRL_TYPE_AV1_FRAME and
initialize tile_info.tile_cols = 1 and tile_info.tile_rows = 1?

No! I cannot edit already emitted tokens, wait—did I just emit that in the response? Let me check if I can avoid that. Too late for what was emitted, stop immediately.

[Severity: High]
Are info->vdiv and info->hdiv swapped in fill_comp()?

In struct v4l2_format_info, hdiv is the horizontal subsampling factor and
vdiv is the vertical subsampling factor. For 4:2:2 formats such as
V4L2_PIX_FMT_APPLE_AX16 and V4L2_PIX_FMT_APPLE_AX23, info->hdiv is 2 and
info->vdiv is 1. Passing width / info->vdiv and height / info->hdiv to
calc_tile_meta() computes tile and power-of-two metadata dimensions for
(width, height / 2) instead of (width / 2, height), which can under-size uv,
uv_meta, comp->offsets[2], and comp->size for asymmetric 4:2:2 resolutions
and lead to capture DMA buffer under-allocation.

Also, since avd_enum_framesizes() allows min_width = 1 and min_height = 1,
can integer division truncate width or height to 0 before calc_tile_meta()
calls roundup_pow_of_two(0), or should DIV_ROUND_UP() be used here?

[Severity: Medium]
Should the comparison in avd_buf_alloc() be size <= buf->size instead of
size < buf->size?

When avd_init_job() calls avd_buf_alloc() on consecutive frames with the
same segment count, size equals buf->size, causing avd_buf_alloc() to free
and reallocate the coherent DMA buffer on every frame.

[Severity: Medium]
Can avd_boot() write past the end of the mapped code region or read past the
end of version[]?

memcpy_toio(avd->code, avd->fw->data, avd->fw->size) does not verify that
avd->fw->size fits within the mapped code resource. In addition,
memcpy_fromio(version, avd->sram, sizeof(version)) copies 64 bytes from SRAM
and passes version to dev_info_once() with %s without ensuring NUL
termination.

[Severity: High]
Can avd_irq_handler() and avd_watchdog_func() race when an interrupt arrives
near the watchdog timeout?

Because avd_irq_handler() is a threaded IRQ handler without synchronization
against avd_watchdog_func():

1. avd_irq_handler() fetches ctx = v4l2_m2m_get_curr_priv(avd->m2m_dev) and
   reads status = 0x1000.
2. Before avd_irq_handler() reaches cancel_delayed_work(&ctx->watchdog_work),
   avd_watchdog_func() can run to completion on another CPU, reset the
   hardware via avd_reset(), and call avd_job_finish(ctx, VB2_BUF_STATE_ERROR).

If another job is queued on ctx, avd_job_finish() schedules the next job and
avd_submit_job() re-arms ctx->watchdog_work; when avd_irq_handler() resumes,
cancel_delayed_work(&ctx->watchdog_work) cancels the new job's watchdog and
prematurely completes the second job while hardware DMA is still active.
Alternatively, if the file descriptor is closing in avd_release(), ctx can be
freed after avd_watchdog_func() finishes, causing avd_irq_handler() to
dereference freed ctx at cancel_delayed_work(&ctx->watchdog_work).

[Severity: Medium]
Should avd_queue_init() also set src_vq->requires_requests = true before
calling vb2_queue_init(src_vq)?

Without requires_requests = true, userspace can queue OUTPUT buffers via
VIDIOC_QBUF without V4L2_BUF_FLAG_REQUEST_FD, locking the queue into
non-request mode and causing avd_run_preamble() to run with src_req == NULL
and unconfigured per-frame stateless controls.

[Severity: Low]
If v4l2_m2m_ctx_init() or avd_init_ctrls() fails in avd_open(), should the
error path call v4l2_fh_exit(&ctx->fh) to pair with v4l2_fh_init(&ctx->fh,
...)?

[Severity: High]
Can avd_watchdog_func() access freed ctx->fh.m2m_ctx during avd_release()?

When a job times out while avd_release() is running:

1. avd_release() calls v4l2_m2m_ctx_release(ctx->fh.m2m_ctx) ->
   v4l2_m2m_cancel_job(), which waits for TRANS_RUNNING to be cleared on
   m2m_ctx->finished.
2. avd_watchdog_func() calls avd_job_finish() -> avd_job_finish_no_pm() ->
   v4l2_m2m_buf_done_and_job_finish(ctx->dev->m2m_dev, ctx->fh.m2m_ctx,
   result).
3. Inside v4l2_m2m_buf_done_and_job_finish(), _v4l2_m2m_job_finish() clears
   TRANS_RUNNING and wakes m2m_ctx->finished before calling
   v4l2_m2m_schedule_next_job(m2m_dev, m2m_ctx).
4. v4l2_m2m_ctx_release() can then return from v4l2_m2m_cancel_job() and
   kfree(m2m_ctx) before avd_release() reaches
   cancel_delayed_work_sync(&ctx->watchdog_work), while avd_watchdog_func()
   is still dereferencing m2m_ctx in v4l2_m2m_schedule_next_job().

[Severity: Medium]
Can an interrupt fire before avd->m2m_dev is initialized in avd_v4l2_init()?

In avd_probe(), devm_request_threaded_irq() registers avd_irq_handler()
before request_firmware(), pm_runtime_enable(), and avd_v4l2_init() (which
initializes avd->m2m_dev via v4l2_m2m_init()). Because avd_irq_handler()
unconditionally calls v4l2_m2m_get_curr_priv(avd->m2m_dev), which
immediately dereferences &m2m_dev->job_spinlock, a pending or spurious
interrupt during probe (or after v4l2_m2m_release() on teardown) will
dereference a NULL or freed avd->m2m_dev pointer.

[Severity: High]
Does the teardown ordering in avd_remove() allow use-after-free of avd->fw or
leave the hardware running on unbind?

In avd_remove():

1. release_firmware(avd->fw) is called before pm_runtime_disable(avd->dev),
   so a runtime resume occurring before runtime PM is disabled can invoke
   avd_runtime_resume() -> avd_boot() and dereference freed avd->fw.
2. Calling pm_runtime_disable(avd->dev) before
   pm_runtime_dont_use_autosuspend(avd->dev) increments disable_depth before
   update_autosuspend() runs, causing rpm_idle() to fail with -EACCES if the
   device is still in its autosuspend window and skipping
   avd_runtime_suspend() -> avd_shutdown().
3. avd_v4l2_cleanup(avd) frees avd->m2m_dev while the devm-managed IRQ and
   CM3 processor may still be active.

[Severity: High]
Does calling VIDIOC_TRY_FMT on the capture queue via avd_try_capture_fmt()
corrupt the active ctx->comp state?

avd_try_capture_fmt() calls avd_fill_decoded_pixfmt(ctx, pix_mp), which
unconditionally overwrites ctx->comp.start_offset, ctx->comp.offsets, and
ctx->comp.size. If userspace invokes VIDIOC_TRY_FMT with a different
pixelformat (such as an interchange format where start_offset is 0) or
different dimensions after setting the format or while streaming,
avd_run_preamble() will use the overwritten ctx->comp to compute
run->comp_out and dst->comp, corrupting the capture buffer or writing past
its end.

[Severity: Medium]
In avd_h264_run(), run.num_valid comes from reflist_builder.num_valid, which
counts DPB entries with V4L2_H264_DPB_ENTRY_FLAG_ACTIVE set (and also builds
h264_ctx->reflists.{p,b0,b1}, which are never read).

Here in stream_refs(), the loop iterates over entries with
V4L2_H264_DPB_ENTRY_FLAG_VALID set while encoding AVD_REF_NUM(run->num_valid -
1). If the DPB holds valid but inactive frames (for example, decoded frames
held for display reordering or during a non-IDR I-frame where num_valid is 0),
won't the number of pushed reference headers mismatch AVD_REF_NUM and
underflow run->num_valid - 1 when run->num_valid is 0?

[Severity: Medium]
Can sl->header_bit_size + 7 overflow a 32-bit unsigned integer when
V4L2_H264_PPS_FLAG_ENTROPY_CODING_MODE is set and sl->header_bit_size >=
0xfffffff9, wrapping min_off to 0?

Also, if stream_slice() returns early here when off > payload_len or
payload_len < min_off, avd_h264_run() still calls avd_end_segment(ctx, false)
and avd_submit_job(ctx). Should stream_slice() return an error code so
avd_h264_run() can abort instead of submitting an empty slice segment to the
hardware?

[Severity: Critical]
Can sl->ref_pic_list1[0].index read past the end of decode->dpb[] here?

sl->ref_pic_list1[0].index is an unvalidated u8 from
V4L2_CID_STATELESS_H264_SLICE_PARAMS, while decode->dpb only has
V4L2_H264_NUM_DPB_ENTRIES (16) elements. Neither std_validate_compound() nor
avd_h264_try_ctrl() checks that ref_pic_list1[0].index <
ARRAY_SIZE(decode->dpb), so a slice with slice_type == V4L2_H264_SLICE_TYPE_B
and index >= 16 (such as 0xff) will read out-of-bounds from decode->dpb.

[Severity: High]
Should avd_h264_validate_sps() also validate that the SPS macroblock
dimensions fit within ctx->coded_fmt and that sps->bit_depth_luma_minus8 is 0
or 2?

avd_h264_alloc_bufs() sizes the internal scratch DMA buffers (above_info,
ip_above, lf_above, lf_above_info, mv_above_info) using fmt_width(ctx) and
ctx->image_fmt, and capture buffers are sized from ctx->decoded_fmt. However,
stream_hdr() programs the hardware with:

	u32 width = (sps->pic_width_in_mbs_minus1 + 1) * 16;
	u32 height = (sps->pic_height_in_map_units_minus1 + 1) * 16;

and sps->bit_depth_luma_minus8 directly from the SPS control. If userspace
supplies an SPS with dimensions or bit depth larger than the configured
format, won't the hardware DMA-write past the end of the scratch and capture
buffers?

[Severity: High]
When avd_stop_streaming() calls avd_h264_stop(), ctx->priv and
ctx->job.segments are not cleared to NULL.

If userspace queues a slice with V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF set, stops
streaming via VIDIOC_STREAMOFF, and restarts streaming via VIDIOC_STREAMON:

1. If avd_h264_start() fails early before reassigning ctx->priv, ctx->priv
   remains a dangling pointer to the freed h264_ctx.
2. If avd_h264_start() succeeds and userspace queues a slice with
   first_mb_in_slice != 0, avd_h264_run() sees ctx->job.segments != NULL from
   before streamoff and submits stale segments containing the DMA addresses of
   the freed scratch and slice buffers.

Should avd_h264_stop() clear ctx->priv = NULL and ctx->job.segments = NULL?

[Severity: High]
If kzalloc_objs() fails when allocating h264_ctx->slices, ret is still 0 from
avd_h264_validate_sps(). Doesn't jumping to err_free_ctx free h264_ctx, set
ctx->priv = NULL, and return 0 to avd_start_streaming(), leading to a NULL
pointer dereference in avd_h264_run()?

Also, since avd_h264_start() runs from avd_start_streaming() outside any
v4l2_ctrl_ops callback, should it inspect ctrl->p_cur.p_h264_sps instead of
ctrl->p_new.p_h264_sps?

[Severity: Critical]
Does the memcpy() into job->segments read past the end of job->buf.cpu here?

On the first slice of a frame, avd_init_job() allocates job->buf with
old_alloc_slice_num + 1 segments. stream_hdr() consumes 1 segment and each of
the first old_alloc_slice_num slices calls avd_end_segment(), which increments
job->num to old_alloc_slice_num + 1. When the next slice triggers
avd_h264_realloc_slices(), job->num already equals the total number of
segments allocated in job->buf.cpu, so copying job->num + 1 segments reads one
struct avd_segment past the end of job->buf.cpu.

In addition, if avd_buf_alloc() fails and returns -ENOMEM (or if the early
return path is taken without updating job->num_alloc), h264_ctx->alloc_slice_num
has already been updated to the larger alloc_slice_num while job->segments
still points to the smaller buffer. Won't subsequent slices then bypass
avd_h264_realloc_slices() and write past the end of job->segments?

[Severity: Critical]
Can h264_ctx->slices[] be written out-of-bounds when
V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF is used?

In avd_h264_run(), the reallocation check:

	if (ctx->job.segments &&
	    h264_ctx->slice_num >= h264_ctx->alloc_slice_num)

is gated on ctx->job.segments being non-NULL, and active_slice is allocated
and h264_ctx->slice_num is incremented before checking is_new_frame() or
!ctx->job.segments.

If ctx->job.segments is NULL and userspace queues buffers with
first_mb_in_slice != 0 and V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF set,
avd_h264_run() increments h264_ctx->slice_num and returns -EINVAL at if
(!ctx->job.segments). Because avd_h264_done() only frees slices and resets
h264_ctx->slice_num when !(src_buf->flags & V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF)
even on VB2_BUF_STATE_ERROR, h264_ctx->slice_num keeps growing while
ctx->job.segments remains NULL, bypassing avd_h264_realloc_slices() and
writing past the end of h264_ctx->slices[].

Similarly, if a new frame (first_mb_in_slice == 0) arrives after prior slices
were held with V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF, avd_init_job() resets
ctx->job.num to 0 without freeing the previous h264_ctx->slices[] or resetting
h264_ctx->slice_num.

[Severity: Medium]
Can ref_buf[i]->vp9.height and ref_buf[i]->vp9.width be 0 here if an earlier
decode run failed?

In avd_vp9_run(), avd_vp9_run_preamble() calls avd_run_preamble() first, which
copies the timestamp to dst and sets copied_timestamp = 1 via
v4l2_m2m_buf_copy_metadata(). However, update_dec_buf_info() is only called
later in avd_vp9_run() after both validate_dec_params() and avd_init_job()
succeed.

If validate_dec_params() or avd_init_job() fails on a newly allocated capture
buffer, the buffer is returned with VB2_BUF_STATE_ERROR while retaining its
copied timestamp and leaving vp9.width and vp9.height as 0. If a subsequent
inter-frame references that timestamp, avd_get_ref_buf() matches that capture
buffer via vb2_find_buffer(), causing ref_buf[i]->vp9.height - 1 and
ref_buf[i]->vp9.width - 1 to underflow to 0xffff.

[Severity: Medium]
Is the ternary condition for VP9_REF_SEL_ALT in make_flags1() inverted when
comparing against golden and last?

Because alt != golden is evaluated first and immediately returns
VP9_ALTREF_FRAME when true, the fallback check alt != last is only reached
when alt == golden. When alt == last and golden != last, alt != golden is
true, so this selects VP9_ALTREF_FRAME instead of deduplicating to
VP9_LAST_FRAME.

Should this check alt == last and alt == golden first, such as:

	flags |= VP9_REF_SEL_ALT(alt == last   ? VP9_LAST_FRAME :
				 alt == golden ? VP9_GOLDEN_FRAME :
						 VP9_ALTREF_FRAME);

[Severity: High]
What happens in set_tiles() if vb2_plane_vaddr() returns NULL?

The output queue supports VB2_DMABUF, and vb2_plane_vaddr() can return NULL if
a user-imported DMABUF fails dma_buf_vmap_unlocked() or does not support vmap.
When a frame has more than one tile (num_tile_rows > 1 or num_tile_cols > 1),
get_unaligned_be32(&data[offset]) dereferences NULL + offset.

For comparison, avd_h264_run() in drivers/media/platform/apple/avd/avd-h264.c
explicitly checks the return value of vb2_plane_vaddr() for NULL and returns
-EINVAL.

[Severity: High]
Can the tile end coordinates underflow in set_tiles() when num_tile_rows >
sb_64_rows or num_tile_cols > sb_64_cols?

validate_vp9_frame() in drivers/media/v4l2-core/v4l2-ctrls-core.c only bounds
tile_cols_log2 <= 6 (num_tile_cols <= 64) and tile_rows_log2 <= 2
(num_tile_rows <= 4), while validate_dec_params() allows resolutions down to
64x64 (sb_64_cols = 1, sb_64_rows = 1). If userspace passes a frame with
num_tile_rows > sb_64_rows or num_tile_cols > sb_64_cols, then for row = 0 or
col = 0 the integer division ((row + 1) * sb_64_rows) / num_tile_rows or
((col + 1) * sb_64_cols) / num_tile_cols evaluates to 0, and subtracting 1
underflows to 0xffffffff (masked to 0xfff in AVD_SL_DIM_END_Y /
AVD_SL_DIM_END_X).

Also, in drivers/media/platform/apple/avd/avd-inst.h:

#define AVD_SL_DIM_END_COL(v)		FIELD_PREP(GENMASK(27, 24), v)

AVD_SL_DIM_END_COL() is a 4-bit field (max 15), whereas tile_cols_log2 can be
up to 6 (col up to 63). Does col get truncated when tile_cols_log2 >= 5?

[Severity: High]
Can the hardware overflow the internal DMA scratch buffers allocated in
avd_vp9_alloc_bufs() if the decoded format or frame bit_depth exceeds the
values present when OUTPUT streaming started?

avd_vp9_alloc_bufs() is only called once from avd_vp9_start() during
VIDIOC_STREAMON on the OUTPUT queue. It sizes the internal DMA buffers
(color, ip_above, lf_above, seg, lf_left, lf_left_info, az_left, above_info)
using fmt_width(ctx) and fmt_height(ctx) (which read ctx->coded_fmt) and
ctx->image_fmt.

However:
1. avd_try_capture_fmt() allows ctx->decoded_fmt to be configured larger than
ctx->coded_fmt, and mid-stream resolution changes update ctx->decoded_fmt
while the OUTPUT queue remains streaming.
2. If VIDIOC_STREAMON(OUTPUT) is called before V4L2_CID_STATELESS_VP9_FRAME is
set, ctx->image_fmt is still AVD_IMG_FMT_ANY, so avd_vp9_alloc_bufs() sizes
the scratch buffers for bit_depth = 8 even if 10-bit frames are subsequently
submitted.
3. validate_dec_params() only checks aligned_width and aligned_height against
ctx->decoded_fmt (not ctx->coded_fmt), and only checks dec_params->bit_depth
<= 10 without verifying that it matches the allocated scratch buffer bit_depth
or capture pixel format.

When set_header() programs the hardware with frame->frame_width_minus_1,
frame->frame_height_minus_1, and frame->bit_depth, won't the decoder DMA past
the end of these scratch buffers?

This patch adds stateless V4L2 HEVC decoding support to the Apple Video
Decoder (AVD) driver.

[Severity: High]
Should stream_slice_mv() use ref->base.vb.vb2_buf.planes[0].length instead
of ref->base.vb.planes[0].length here?

In avd_hevc_run_preamble(), the destination buffer's mv_color address is
computed from vb2_buf.planes[0].length:

	dst_len = run->base.bufs.dst->vb2_buf.planes[0].length;
	mv_color_len = mv_color_size(fmt_width(ctx), fmt_height(ctx));
	run->addresses.mv_color = run->base.y_out + (dst_len - mv_color_len);

When capture buffers are queued using VB2_MEMORY_DMABUF with
v4l2_plane.length set to 0, __prepare_dmabuf() in videobuf2-core.c sets
vb2_buf.planes[0].length = dbuf->size, while leaving
vb2_v4l2_buffer.planes[0].length as 0.

When decoding a P or B slice with
V4L2_HEVC_SLICE_PARAMS_FLAG_SLICE_TEMPORAL_MVP_ENABLED and a non-intra
collocated reference frame, subtracting mv_color_size() from
ref->base.vb.planes[0].length (0) underflows the 32-bit unsigned value and
programs the hardware with an out-of-bounds DMA address.

Also, in set_slice(), coded_in and size are computed from sl->bit_size,
sl->data_byte_offset, and entry_point_offsets without bounds checking
against the source buffer plane size.

[Severity: High]
Can submit_slice_segment() read past the end of row_bd[] on the stack?

In stream_slices(), pos is incremented for every segment where
(slice_flag & NEW_TILE_ID) is set, and row is computed as:

	row = pos / num_cols;
	col = pos % num_cols;

Across up to 1800 slices and 1760 entry point offsets, pos can reach up to
3560 while num_cols (pps->num_tile_columns_minus1 + 1) can be 1. Because
row is not checked against pps->num_tile_rows_minus1 or HEVC_MAX_TILE_ROWS,
submit_slice_segment() can index row_bd[row] and row_bd[row + 1] past the
end of run.tile_info.row_bd[HEVC_MAX_TILE_ROWS + 1].

Note also that submit_slice_segment() declares u32 col_bd[23] and
u32 row_bd[23], which do not match HEVC_MAX_TILE_COLS + 1 and
HEVC_MAX_TILE_ROWS + 1.

[Severity: Critical]
Can compute_tiles_non_uniform() read out of bounds from
pps->column_width_minus1[] and pps->row_height_minus1[]?

In include/uapi/linux/v4l2-controls.h, struct v4l2_ctrl_hevc_pps defines:

	__u8 column_width_minus1[20];
	__u8 row_height_minus1[22];

However, HEVC_MAX_TILE_COLS is 40 and HEVC_MAX_TILE_ROWS is 44, so
avd_hevc_validate_pps() allows pps->num_tile_columns_minus1 up to 39 and
pps->num_tile_rows_minus1 up to 43. When V4L2_HEVC_PPS_FLAG_TILES_ENABLED
is set without V4L2_HEVC_PPS_FLAG_UNIFORM_SPACING, these loops read
pps->column_width_minus1[i] up to index 38 and pps->row_height_minus1[i]
up to index 42, reading past both arrays and the end of struct
v4l2_ctrl_hevc_pps.

[Severity: Critical]
In addition, what happens in compute_tiles_non_uniform() if the cumulative
sum of column widths or row heights exceeds pic_in_cts_width or
pic_in_cts_height?

Clamping each individual column or row with MIN() does not prevent sum from
exceeding pic_in_cts_width or pic_in_cts_height across multiple columns or
rows. When sum > pic_in_cts_width (or sum > pic_in_cts_height), the final
assignment:

	column_width[i] = pic_in_cts_width - sum;
	...
	row_height[i] = pic_in_cts_height - sum;

underflows in u16 to a large value (up to 65535). compute_bd() then
computes col_bd and row_bd boundaries exceeding pic_in_ctbs_width and
pic_in_ctbs_height, causing compute_tile_ids() to read
ctb_addr_rs_to_ts[y * pic_in_ctbs_width + x] and write tile_ids[...] out of
bounds on the heap:

[Severity: High]
Does avd_hevc_validate_sps() also need to validate that picture dimensions
are non-zero and bound log2_min_luma_coding_block_size_minus3 and
log2_diff_max_min_luma_coding_block_size?

In avd_hevc_run(), avd_hevc_compute_tiles() runs before
avd_hevc_alloc_scratch() (where the !max_cu_width check is located) and
executes:

	log2_min_cb_size = sps->log2_min_luma_coding_block_size_minus3 + 3;

	max_cu_width = 1 << (sps->log2_diff_max_min_luma_coding_block_size +
			     log2_min_cb_size);
	pic_in_ctbs_width = (width + max_cu_width - 1) / max_cu_width;
	pic_in_ctbs_height = (height + max_cu_width - 1) / max_cu_width;
	pic_in_ctbs_size = pic_in_ctbs_height * pic_in_ctbs_width;

If the shift exponent is >= 31, 1 << ... triggers signed 32-bit shift
undefined behavior; if it is >= 32 (or wraps to 0), dividing by max_cu_width
divides by zero, and if it is 31, max_cu_width is 0x80000000, making
pic_in_ctbs_width = 0 and causing division by zero in compute_rs_to_ts() or
submit_slice_segment(), as well as 32-bit overflow in
((max_col * max_cu_width) / 4) * bit_depth in avd_hevc_alloc_scratch().

Similarly, if width or height is 0 (for example, if streaming starts before
setting V4L2_CID_STATELESS_HEVC_SPS), pic_in_ctbs_size is 0 and
kzalloc_objs() returns ZERO_SIZE_PTR, which is then dereferenced. Also,
because avd_hevc_validate_sps() is only called from avd_hevc_try_ctrl(),
decreasing the coded format dimensions via VIDIOC_S_FMT after setting the
SPS control leaves stale SPS dimensions larger than the format.

[Severity: Critical]
Can sum overflow when accumulating (*run->sl)[i].num_entry_point_offsets in
avd_hevc_run_preamble()?

(*run->sl)[i].num_entry_point_offsets is an unvalidated __u32 accumulated
into a 32-bit signed int sum. If two or more slices have
num_entry_point_offsets values whose 32-bit sum wraps to 0 or to
run->num_entry_point_offsets, this check passes while avd_init_job() only
allocates run.num_slices + run.num_entry_point_offsets + 1 segments.

In stream_slices():

	to = tiles_enabled ? sl->num_entry_point_offsets + 1 : 1;

	for (i = 0; i < to; i++) {
		...
		if (tiles_enabled && to > 1) {
			if (i < sl->num_entry_point_offsets) {
				size = (*run->entry_point_offsets)
					       [entry_point_idx++];

When tiles_enabled is true, this loop can then read
(*run->entry_point_offsets)[entry_point_idx++] out of bounds on the heap
and write past the end of ctx->job.segments via push() and
avd_end_segment(). Moreover, if sl->num_entry_point_offsets >= 0x7fffffff,
int to = sl->num_entry_point_offsets + 1 overflows to <= 0, skipping the
inner loop and its sl->slice_segment_addr >= pic_in_ctbs_size check for
slice s, so slice s + 1 indexes
tile_info->ctb_addr_rs_to_ts[(*run->sl)[s].slice_segment_addr] out of
bounds.

[Severity: High]
In avd_av1_get_ref_buf(), frame->ref_frame_idx is declared as
__s8 ref_frame_idx[V4L2_AV1_REFS_PER_FRAME] (7 signed elements), whereas
V4L2_AV1_TOTAL_REFS_PER_FRAME is 8.

If idx == 7, or if frame->ref_frame_idx[idx] is negative (since __s8 is
signed and not cast to unsigned before comparing with ARRAY_SIZE()), will
this read out of bounds on frame->ref_frame_idx[] or
frame->reference_frame_ts[]?

[Severity: Medium]
In set_refs(), alpha, beta, gamma, and delta are initialized to 0 once
outside the reference frame loop, and avd_av1_dec_get_shear_params()
returns early without modifying them when mat[2] <= 0.

If an earlier reference frame has gm->params[ref_idx][2] > 0 and a
subsequent reference frame has gm->params[ref_idx][2] <= 0, won't the
subsequent iteration push stale alpha, beta, gamma, and delta values from
the earlier reference frame?

[Severity: Medium]
In avd_av1_get_dist(), seq->order_hint_bits is an unvalidated __u8 from
V4L2_CID_STATELESS_AV1_SEQUENCE (neither validate_av1_sequence() in
v4l2-ctrls-core.c nor avd_av1_validate_sequence() bounds it).

If userspace sets seq->order_hint_bits > 8 (for instance >= 32), can
1 << bits trigger a shift-out-of-bounds on the 32-bit signed int and
overflow AV1_HDR_ORDER_HINT_BITS() in set_header()?

[Severity: High]
In set_ref_hdr() (called unconditionally from avd_av1_run() ->
set_header()), frame->ref_frame_idx[i] and frame->ref_frame_idx[j] are
signed __s8 values from userspace (-128..127) that are not validated by
validate_av1_frame() or the driver, and may also be -1 on intra frames.

Does indexing frame->reference_frame_ts[] (8 elements) directly with
frame->ref_frame_idx[i] and frame->ref_frame_idx[j] without bounds
checking read out of bounds?

[Severity: High]
set_header() calls calc_upscale() unconditionally with
frame->upscaled_width, which is not validated by v4l2-ctrls-core.c or
this driver.

If userspace leaves frame->upscaled_width as 0 (or passes 0xffffffff
when sub_x == 1), upscaled_plane_w evaluates to 0. Similarly, in
set_refs(), if frame->frame_width_minus_1 or frame->frame_height_minus_1
is 0xffffffff, width or height wraps to 0. Can this trigger a division
by zero in calc_upscale() and set_refs()?

[Severity: High]
In set_tiles(), tile_group->tile_row and tile_group->tile_col are __u32
fields assigned to signed int variables tile_row and tile_col, which are
only checked for >= V4L2_AV1_MAX_TILE_COLS / V4L2_AV1_MAX_TILE_ROWS.

If userspace passes a value >= 0x80000000U for tile_row or tile_col, won't
tile_row or tile_col become negative, bypass the upper-bound check, and
index tile_info->mi_row_starts[], mi_col_starts[], height_in_sbs_minus_1[],
and width_in_sbs_minus_1[] at negative offsets? Should tile_offset and
tile_size also be validated against the source buffer size?

[Severity: High]
In avd_av1_set_prob(), vb2_plane_vaddr() is called on ref->base.vb.vb2_buf
and dst->base.vb.vb2_buf without checking for NULL before adding
AVD_AV1_CDFS_OFFSET() and passing the pointer to memcpy().

Since the capture queue supports VB2_DMABUF, vb2_dc_vaddr() can return
NULL if dma_buf_vmap_unlocked() fails or is unsupported by the exporter.
Additionally, should run->frame->primary_ref_frame == 7 check
>= V4L2_AV1_REFS_PER_FRAME instead?

[Severity: High]
In avd_av1_run_preamble(), run->tile_group is read from ctrl->p_cur.p,
whose element count is stored in ctrl->elems rather than ctrl->new_elems.

If userspace updates ctrl->new_elems via VIDIOC_TRY_EXT_CTRLS or on
another request while ctrl->p_cur.p has fewer elements in ctrl->elems,
can set_tiles() read past the end of run->tile_group?

[Severity: Critical]
In avd_av1_adjust_decoded_fmt(), the capture buffer size is computed from
ctx->decoded_fmt.fmt.pix_mp.width and height, but unlike avd-vp9.c and
avd-hevc.c, avd-av1.c never checks that frame->frame_width_minus_1 + 1 and
frame->frame_height_minus_1 + 1 fit within the negotiated capture format
dimensions (and avd_color_size() uses signed 32-bit int arithmetic).

If userspace submits a frame control with dimensions larger than the
negotiated capture format, AVD_AV1_CDFS_OFFSET(dst_len, dst->av1.color_size)
underflows when dst->av1.color_size exceeds planes[0].length. Won't
avd_av1_set_prob() then memcpy() sizeof(struct avd_av1_cdfs) out of bounds
before the start of the capture buffer, and program out-of-bounds DMA
addresses for color and probs_out?

[Severity: High]
In avd_av1_alloc_work_bufs(), tile_info->width_in_sbs_minus_1[i] and
tile_info->height_in_sbs_minus_1[i] are unvalidated __u32 values from
userspace, and the buffer size calculations are performed in 32-bit u32
arithmetic.

Can large values in width_in_sbs_minus_1[], height_in_sbs_minus_1[], w, or
h overflow these 32-bit calculations and allocate undersized DMA scratch
buffers for the hardware?

[Severity: High]
In avd_av1_alloc_work_bufs(), av1_ctx->bufs.seg is only allocated when
V4L2_AV1_SEGMENTATION_FLAG_UPDATE_MAP is set, while set_header() sets
AV1_FLAGS_SEG_ENABLED() when V4L2_AV1_SEGMENTATION_FLAG_ENABLED is set and
unconditionally pushes av1_ctx->bufs.seg.addr (as well as hardcoded poison
IOVAs 0xb0b0b0b0 and 0xa0a0a0a0).

What happens if a frame has V4L2_AV1_SEGMENTATION_FLAG_ENABLED set without
V4L2_AV1_SEGMENTATION_FLAG_UPDATE_MAP before av1_ctx->bufs.seg has been
allocated (leaving seg.addr == 0), or when resolution increases? Also,
since avd_buf_alloc() frees and reallocates whenever size == buf->size,
won't calling avd_buf_alloc() on same-sized UPDATE_MAP frames zero out the
previous segmentation map?

[Severity: Critical]
Enabling the video-codec@269070000 node exposes the AVD V4L2 M2M stateless
decoder to userspace. Can crafted HEVC controls trigger out-of-bounds memory
accesses and division by zero in drivers/media/platform/apple/avd/avd-hevc.c
through avd_device_run() -> avd_hevc_run()?

First, struct v4l2_ctrl_hevc_pps defines column_width_minus1[20] and
row_height_minus1[22], and std_validate_compound() in
drivers/media/v4l2-core/v4l2-ctrls-core.c does not bound
num_tile_columns_minus1 or num_tile_rows_minus1 when
V4L2_HEVC_PPS_FLAG_TILES_ENABLED is set. However, avd_hevc_validate_pps()
allows up to HEVC_MAX_TILE_COLS (40) and HEVC_MAX_TILE_ROWS (44):

drivers/media/platform/apple/avd/avd-hevc.c:avd_hevc_validate_pps() {
	if (pps->num_tile_columns_minus1 + 1 > HEVC_MAX_TILE_COLS ||
	    pps->num_tile_rows_minus1 + 1 > HEVC_MAX_TILE_ROWS)
		return -EINVAL;
}

When compute_tiles_non_uniform() iterates up to pps->num_tile_columns_minus1
and pps->num_tile_rows_minus1:

drivers/media/platform/apple/avd/avd-hevc.c:compute_tiles_non_uniform() {
	for (i = 0; i < pps->num_tile_columns_minus1; i++) {
		column_width[i] = MIN(pps->column_width_minus1[i] + 1,
				      pic_in_cts_width);
		sum += column_width[i];
	}
	column_width[i] = pic_in_cts_width - sum;

	sum = 0;
	for (i = 0; i < pps->num_tile_rows_minus1; i++) {
		row_height[i] = MIN(pps->row_height_minus1[i] + 1,
				    pic_in_cts_height);
		sum += row_height[i];
	}
	row_height[i] = pic_in_cts_height - sum;
}

Doesn't this read past pps->column_width_minus1[20] and
pps->row_height_minus1[22] (and past the end of struct v4l2_ctrl_hevc_pps)?

Second, in compute_tiles_non_uniform() above, each entry is only clamped
individually to pic_in_cts_width or pic_in_cts_height. If sum exceeds
pic_in_cts_width or pic_in_cts_height, won't the u16 assignment to
column_width[i] or row_height[i] underflow to a large positive value, causing
compute_bd() to produce col_bd and row_bd entries larger than
pic_in_ctbs_width and pic_in_ctbs_height, which then overflows the heap-
allocated ctb_addr_rs_to_ts and tile_ids arrays in compute_rs_to_ts() and
compute_tile_ids()?

drivers/media/platform/apple/avd/avd-hevc.c:compute_tile_ids() {
	for (j = 0, tile_idx = 0; j <= pps->num_tile_rows_minus1; j++)
		for (i = 0; i <= pps->num_tile_columns_minus1; i++, tile_idx++)
			for (y = row_bd[j]; y < row_bd[j + 1]; y++)
				for (x = col_bd[i]; x < col_bd[i + 1]; x++)
					tile_ids[ctb_addr_rs_to_ts
							 [y * pic_in_ctbs_width +
							  x]] = tile_idx;
}

Third, avd_hevc_validate_sps() does not reject zero
pic_width_in_luma_samples / pic_height_in_luma_samples or out-of-range
log2_min_luma_coding_block_size_minus3 /
log2_diff_max_min_luma_coding_block_size. In avd_hevc_compute_tiles():

drivers/media/platform/apple/avd/avd-hevc.c:avd_hevc_compute_tiles() {
	max_cu_width = 1 << (sps->log2_diff_max_min_luma_coding_block_size +
			     log2_min_cb_size);
	pic_in_ctbs_width = (width + max_cu_width - 1) / max_cu_width;
	pic_in_ctbs_height = (height + max_cu_width - 1) / max_cu_width;
	pic_in_ctbs_size = pic_in_ctbs_height * pic_in_ctbs_width;
}

Can this shift out of bounds and divide by zero before avd_hevc_alloc_scratch()
checks if (!max_cu_width), or result in ZERO_SIZE_PTR dereferences when width
or height is zero?

[Severity: Critical]
In drivers/media/platform/apple/avd/avd-hevc.c, can avd_hevc_run_preamble()
and stream_slices() also overflow when validating and iterating HEVC slice
segments?

In avd_hevc_run_preamble(), sum is a 32-bit signed int accumulating __u32
num_entry_point_offsets across up to 1800 slices:

drivers/media/platform/apple/avd/avd-hevc.c:avd_hevc_run_preamble() {
	for (i = 0; i < run->num_slices; i++)
		sum += (*run->sl)[i].num_entry_point_offsets;

	if (sum && sum != run->num_entry_point_offsets)
		return -EINVAL;
}

Since std_validate_compound() does not bound num_entry_point_offsets, can
crafted values (for example, sl[0].num_entry_point_offsets = 2 and
sl[1].num_entry_point_offsets = 0xfffffffe) overflow sum to 0 or a small
value matching run->num_entry_point_offsets? That causes avd_init_job() to
allocate only run.num_slices + run.num_entry_point_offsets + 1 segments in
ctx->job.segments while stream_slices() loops sl->num_entry_point_offsets + 1
times, reading past (*run->entry_point_offsets) and writing past
ctx->job.segments via push() and avd_end_segment().

Additionally, in stream_slices(), pos is incremented for every segment with
NEW_TILE_ID:

drivers/media/platform/apple/avd/avd-hevc.c:stream_slices() {
			row = pos / num_cols;
			col = pos % num_cols;
}

and passed to submit_slice_segment():

drivers/media/platform/apple/avd/avd-hevc.c:submit_slice_segment() {
		if (pps->flags & V4L2_HEVC_PPS_FLAG_TILES_ENABLED)
			push(AVD_SL_DIM_END_ROW((hflip ? 4 : 0) |
						(vflip ? 8 : 0)) |
				     AVD_SL_DIM_END_COL(col) |
				     AVD_SL_DIM_END_Y(row_bd[row + 1] - 1) |
				     AVD_SL_DIM_END_X(col_bd[col + 1] - 1),
			     "cm3_set_ctb_xy");
}

Without checking that row <= pps->num_tile_rows_minus1, won't pos / num_cols
exceed HEVC_MAX_TILE_ROWS and read row_bd[row] and row_bd[row + 1] out of
bounds on the stack?

[Severity: Critical]
In drivers/media/platform/apple/avd/avd-h264.c (enabled on T8103 via
AVD_CAPABILITY_H264), are there also out-of-bounds accesses and an uninitialized
error return reachable from userspace?

1. In stream_slice(), sl->ref_pic_list1[0].index is an unvalidated u8 from
V4L2_CID_STATELESS_H264_SLICE_PARAMS (not checked by std_validate_compound()
in drivers/media/v4l2-core/v4l2-ctrls-core.c):

drivers/media/platform/apple/avd/avd-h264.c:stream_slice() {
		/* sl->ref_pic_list1[0].index < ARRAY_SIZE(decode->dpb) */
		/* bidirectional reference of previous mv */
		ref = avd_get_ref_buf(
			ctx, &dst->base.vb,
			decode->dpb[sl->ref_pic_list1[0].index].reference_ts);
}

Doesn't this read past the 16-entry decode->dpb array when index >= 16?

2. In avd_h264_realloc_slices(), when h264_ctx->slice_num reaches
h264_ctx->alloc_slice_num, job->num is already alloc_slice_num + 1 (1 header
segment from stream_hdr() plus alloc_slice_num slice segments from
stream_slice()), matching the allocated capacity of job->buf.cpu:

drivers/media/platform/apple/avd/avd-h264.c:avd_h264_realloc_slices() {
	memcpy(job->segments, job->buf.cpu,
	       sizeof(*job->segments) * (job->num + 1));
}

Won't copying job->num + 1 entries read one struct avd_segment past the end of
job->buf.cpu (and if job->buf.size is already large enough earlier in
avd_h264_realloc_slices(), return 0 without updating job->num_alloc)?

3. In avd_h264_run(), avd_h264_realloc_slices() is only called when
ctx->job.segments is non-NULL:

drivers/media/platform/apple/avd/avd-h264.c:avd_h264_run() {
	if (ctx->job.segments &&
	    h264_ctx->slice_num >= h264_ctx->alloc_slice_num) {
		ret = avd_h264_realloc_slices(ctx);
		if (ret)
			goto postamble;
	}

	h264_ctx->active_slice = &h264_ctx->slices[h264_ctx->slice_num];
}

Since avd_h264_done() only resets h264_ctx->slice_num when
V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF is not set, what happens if userspace
submits slices with first_mb_in_slice != 0 and
V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF set? With ctx->job.segments still NULL,
won't h264_ctx->slice_num increment past h264_ctx->alloc_slice_num and write
past the end of h264_ctx->slices?

4. In avd_h264_start(), ret is 0 after avd_h264_validate_sps() succeeds:

drivers/media/platform/apple/avd/avd-h264.c:avd_h264_start() {
	h264_ctx->slices = kzalloc_objs(*h264_ctx->slices,
					h264_ctx->alloc_slice_num, GFP_KERNEL);
	if (!h264_ctx->slices)
		goto err_free_ctx;
}

If kzalloc_objs() fails here, doesn't avd_h264_start() free h264_ctx, set
ctx->priv = NULL, and return 0 to avd_start_streaming(), causing a NULL
pointer dereference in avd_h264_run()?

[Severity: Critical]
In drivers/media/platform/apple/avd/avd-vp9.c and
drivers/media/platform/apple/avd/avd-av1.c, could several missing bounds and
NULL checks cause crashes or out-of-bounds memory accesses?

1. In avd-vp9.c (enabled on T8103 via AVD_CAPABILITY_VP9), set_tiles() calls
vb2_plane_vaddr() on a VB2_DMABUF-capable queue:

drivers/media/platform/apple/avd/avd-vp9.c:set_tiles() {
	const u8 *data = vb2_plane_vaddr(&src->vb2_buf, 0);
...
				tile_size = get_unaligned_be32(&data[offset]);
}

and in avd-av1.c, avd_av1_set_prob() also calls vb2_plane_vaddr() without
checking for NULL:

drivers/media/platform/apple/avd/avd-av1.c:avd_av1_set_prob() {
	memcpy(vb2_plane_vaddr(&dst->base.vb.vb2_buf, 0) +
		       AVD_AV1_CDFS_OFFSET(dst->base.vb.vb2_buf.planes[0].length,
					   dst->av1.color_size),
	       av1_ctx->bufs.probs.cpu, sizeof(struct avd_av1_cdfs));
}

Since vb2_dc_vaddr() returns NULL if dma_buf_vmap_unlocked() fails or is not
supported by the exporter, can these dereference NULL?

2. In avd_av1_set_prob() above, neither validate_av1_frame() nor avd-av1.c
validates frame->frame_width_minus_1 + 1 and frame->frame_height_minus_1 + 1
against the CAPTURE buffer dimensions. If update_dec_buf_info() computes
dst->av1.color_size larger than dst->base.vb.vb2_buf.planes[0].length, won't
AVD_AV1_CDFS_OFFSET() underflow and cause memcpy() to write out of bounds
before the buffer?

3. In drivers/media/platform/apple/avd/avd-av1.c:set_tiles(), __u32
tile_group->tile_row and tile_group->tile_col are assigned to signed int
before the bounds check:

drivers/media/platform/apple/avd/avd-av1.c:set_tiles() {
			tile_row = tile_group->tile_row;
			tile_col = tile_group->tile_col;

			if (tile_col >= V4L2_AV1_MAX_TILE_COLS ||
			    tile_row >= V4L2_AV1_MAX_TILE_ROWS)
				return -EINVAL;
}

Can values >= 0x80000000 become negative, bypass this check, and index
tile_info arrays out of bounds?

4. In drivers/media/platform/apple/avd/avd-av1.c:set_ref_hdr(),
frame->ref_frame_idx[i] (__s8) is not validated by validate_av1_frame():

drivers/media/platform/apple/avd/avd-av1.c:set_ref_hdr() {
			if (frame->reference_frame_ts[frame->ref_frame_idx[i]] ==
			    frame->reference_frame_ts[frame->ref_frame_idx[j]]) {
}

Can negative or out-of-range ref_frame_idx values index out of bounds of
frame->reference_frame_ts[8]? Similarly, avd_av1_get_ref_buf() checks idx
against V4L2_AV1_TOTAL_REFS_PER_FRAME (8) instead of V4L2_AV1_REFS_PER_FRAME
(7) before indexing frame->ref_frame_idx[7], and avd_av1_set_prob() only
checks primary_ref_frame == 7 rather than >= V4L2_AV1_REFS_PER_FRAME.

5. In drivers/media/platform/apple/avd/avd-av1.c:avd_av1_run_preamble():

drivers/media/platform/apple/avd/avd-av1.c:avd_av1_run_preamble() {
	if (run->frame->tile_info.tile_cols * run->frame->tile_info.tile_rows >
		ctrl->new_elems)
		return -EINVAL;
}

Should this check ctrl->elems instead of ctrl->new_elems when reading from
ctrl->p_cur.p?

6. In drivers/media/platform/apple/avd/avd-av1.c:calc_upscale():

drivers/media/platform/apple/avd/avd-av1.c:calc_upscale() {
	*step_x = ((downscaled_plane_w << SUPERRES_SCALE_BITS) +
		   (upscaled_plane_w / 2)) /
		  upscaled_plane_w;
}

If frame->upscaled_width is 0, won't upscaled_plane_w be 0 and trigger a
division by zero?

7. In drivers/media/platform/apple/avd/avd-av1.c:set_refs(), alpha, beta,
gamma, and delta are declared outside the reference loop:

drivers/media/platform/apple/avd/avd-av1.c:set_refs() {
	s64 alpha = 0, beta = 0, gamma = 0, delta = 0;
}

Since avd_av1_dec_get_shear_params() returns early without clearing its output
parameters when mat[2] <= 0, won't a subsequent reference frame reuse stale
shear parameters from an earlier iteration?

[Severity: High]
In drivers/media/platform/apple/avd/avd-drv.c, are info->vdiv and info->hdiv
swapped when fill_comp() calculates the UV plane size and metadata?

drivers/media/platform/apple/avd/avd-drv.c:fill_comp() {
	/* uv has 16x16 tiles and 8 bytes of metadata per tile */
	calc_tile_meta(width / info->vdiv, height / info->hdiv,
		       v4l2_format_info_bpp(info, 1), 16, 8, &uv,
		       &uv_meta);
}

In drivers/media/v4l2-core/v4l2-common.c:v4l2_format_info(), the 4:2:2 formats
V4L2_PIX_FMT_APPLE_AX16 and V4L2_PIX_FMT_APPLE_AX23 define .hdiv = 2 and
.vdiv = 1. Passing width / info->vdiv and height / info->hdiv to
calc_tile_meta(u32 w, u32 h, ...) divides width by 1 and height by 2 instead
of width / info->hdiv and height / info->vdiv, which miscalculates the UV tile
count, UV metadata offset (comp->offsets[2]), and total buffer size
(comp->size) whenever width or height is an odd multiple of 16.

[Severity: Low]
Does Documentation/devicetree/bindings/iommu/apple,dart.yaml need to be
updated to include "apple,t8122-dart"?

Currently the schema only documents:

  compatible:
    oneOf:
      - enum:
          - apple,t8103-dart
          - apple,t8103-usb4-dart
          - apple,t8110-dart
          - apple,t6000-dart
      - items:
          - const: apple,t6020-dart
          - const: apple,t8110-dart

Because "apple,t8110-dart" selects apple,dart.yaml and "apple,t8122-dart"
is not listed there, running make dtbs_check will fail schema validation
on t8122 device trees.

[Severity: Critical]
Enabling video-codec@289070000 with "apple,t8122-avd" exposes the AVD
driver (avd_t8122_variant) to userspace. Looking at the HEVC support in
drivers/media/platform/apple/avd/avd-hevc.c added earlier in the series,
can avd_hevc_validate_pps() and compute_tiles_non_uniform() read and write
out of bounds when userspace submits V4L2_CID_STATELESS_HEVC_PPS and
V4L2_CID_STATELESS_HEVC_SPS controls?

In struct v4l2_ctrl_hevc_pps, column_width_minus1 has 20 elements and
row_height_minus1 has 22 elements, but avd_hevc_validate_pps() checks
against HEVC_MAX_TILE_COLS (40) and HEVC_MAX_TILE_ROWS (44):

	if (pps->num_tile_columns_minus1 + 1 > HEVC_MAX_TILE_COLS ||
	    pps->num_tile_rows_minus1 + 1 > HEVC_MAX_TILE_ROWS)
		return -EINVAL;

When V4L2_HEVC_PPS_FLAG_UNIFORM_SPACING is not set,
avd_hevc_run() -> avd_hevc_compute_tiles() -> compute_tiles_non_uniform()
loops i up to pps->num_tile_columns_minus1 - 1 and
pps->num_tile_rows_minus1 - 1:

	for (i = 0; i < pps->num_tile_columns_minus1; i++) {
		column_width[i] = MIN(pps->column_width_minus1[i] + 1,
				      pic_in_cts_width);
		sum += column_width[i];
	}
	column_width[i] = pic_in_cts_width - sum;

	sum = 0;
	for (i = 0; i < pps->num_tile_rows_minus1; i++) {
		row_height[i] = MIN(pps->row_height_minus1[i] + 1,
				    pic_in_cts_height);
		sum += row_height[i];
	}
	row_height[i] = pic_in_cts_height - sum;

Can this read pps->column_width_minus1[i] and pps->row_height_minus1[i]
out of bounds? Also, because each entry is only clamped individually to
pic_in_cts_width or pic_in_cts_height, if sum exceeds pic_in_cts_width or
pic_in_cts_height, column_width[i] and row_height[i] underflow u16, which
then causes compute_bd() and compute_tile_ids() to index
ctb_addr_rs_to_ts[] and tile_ids[] out of bounds:

	for (j = 0, tile_idx = 0; j <= pps->num_tile_rows_minus1; j++)
		for (i = 0; i <= pps->num_tile_columns_minus1; i++, tile_idx++)
			for (y = row_bd[j]; y < row_bd[j + 1]; y++)
				for (x = col_bd[i]; x < col_bd[i + 1]; x++)
					tile_ids[ctb_addr_rs_to_ts
							 [y * pic_in_ctbs_width +
							  x]] = tile_idx;

Furthermore, in avd_hevc_compute_tiles() (which runs in avd_hevc_run()
before avd_hevc_alloc_scratch()):

	max_cu_width = 1 << (sps->log2_diff_max_min_luma_coding_block_size +
			     log2_min_cb_size);
	pic_in_ctbs_width = (width + max_cu_width - 1) / max_cu_width;
	pic_in_ctbs_height = (height + max_cu_width - 1) / max_cu_width;

If the unvalidated SPS coding block size fields shift out to 0, or if
sps->pic_width_in_luma_samples / pic_height_in_luma_samples is 0, can this
divide by zero in avd_hevc_compute_tiles() or compute_rs_to_ts()?

[Severity: Critical]
Also in the AV1, VP9, and H.264 paths enabled by "apple,t8122-avd", are
there several missing validations on userspace control and buffer parameters?

1. In drivers/media/platform/apple/avd/avd-av1.c, frame->frame_width_minus_1
and frame->frame_height_minus_1 are not checked against
ctx->decoded_fmt.fmt.pix_mp.width and height. In avd_av1_set_prob():

	memcpy(vb2_plane_vaddr(&dst->base.vb.vb2_buf, 0) +
		       AVD_AV1_CDFS_OFFSET(dst->base.vb.vb2_buf.planes[0].length,
					   dst->av1.color_size),
	       av1_ctx->bufs.probs.cpu, sizeof(struct avd_av1_cdfs));

If dst->av1.color_size (derived from frame_width_minus_1 + 1 and
frame_height_minus_1 + 1) exceeds planes[0].length, can
AVD_AV1_CDFS_OFFSET and AVD_AV1_COLOR_OFFSET underflow, causing memcpy()
and hardware DMA to write out of bounds? Similarly, in avd-h264.c,
avd_h264_validate_sps() does not check SPS dimensions against
ctx->coded_fmt or ctx->decoded_fmt, while avd_h264_alloc_bufs() allocates
scratch buffers using fmt_width(ctx) and stream_hdr() programs hardware
with the SPS dimensions.

2. In avd_av1_set_prob() (drivers/media/platform/apple/avd/avd-av1.c) and
set_tiles() (drivers/media/platform/apple/avd/avd-vp9.c):

	struct vb2_v4l2_buffer *src = v4l2_m2m_next_src_buf(ctx->fh.m2m_ctx);
	const u8 *data = vb2_plane_vaddr(&src->vb2_buf, 0);

Since avd_queue_init() enables VB2_DMABUF, can vb2_plane_vaddr() return
NULL and trigger a NULL pointer dereference when accessed without a check?

3. In avd_av1_run_preamble() (drivers/media/platform/apple/avd/avd-av1.c):

	if (run->frame->tile_info.tile_cols * run->frame->tile_info.tile_rows >
		ctrl->new_elems)
		return -EINVAL;

Since this validates ctrl->p_cur.p during a run, should this check
ctrl->elems instead of ctrl->new_elems?

4. In set_tiles() (drivers/media/platform/apple/avd/avd-av1.c):

			tile_row = tile_group->tile_row;
			tile_col = tile_group->tile_col;

			if (tile_col >= V4L2_AV1_MAX_TILE_COLS ||
			    tile_row >= V4L2_AV1_MAX_TILE_ROWS)
				return -EINVAL;

Because tile_row and tile_col are signed int while tile_group->tile_row
and tile_group->tile_col are __u32, can values >= 0x80000000 become
negative, bypass the upper-bound check, and index tile_info arrays out of
bounds?

5. In calc_upscale() (drivers/media/platform/apple/avd/avd-av1.c):

	upscaled_plane_w = AV1_DIV_ROUND_UP_POW2(upscaled_width, sub_x);
	*step_x = ((downscaled_plane_w << SUPERRES_SCALE_BITS) +
		   (upscaled_plane_w / 2)) /
		  upscaled_plane_w;

And in set_refs() in the same file, can frame->upscaled_width == 0 or
frame_width_minus_1 / frame_height_minus_1 == U32_MAX cause a division by
zero?

[Severity: High]
In drivers/media/platform/apple/avd/avd-h264.c, what happens if the slice
array allocation fails in avd_h264_start()?

	ret = avd_h264_validate_sps(ctx, ctrl->p_new.p_h264_sps);
	if (ret)
		return ret;

	h264_ctx = kzalloc_obj(*h264_ctx, GFP_KERNEL);
	if (!h264_ctx)
		return -ENOMEM;

	ctx->priv = h264_ctx;

	/* assume one slice per row */
	h264_ctx->alloc_slice_num =
		ctrl->p_new.p_h264_sps->pic_height_in_map_units_minus1 + 1;
	h264_ctx->slices = kzalloc_objs(*h264_ctx->slices,
					h264_ctx->alloc_slice_num, GFP_KERNEL);
	if (!h264_ctx->slices)
		goto err_free_ctx;
...
err_free_ctx:
	avd_h264_stop(ctx);
	ctx->priv = NULL;
	return ret;

When kzalloc_objs() returns NULL, ret is still 0 from
avd_h264_validate_sps(). Jumping to err_free_ctx frees h264_ctx, sets
ctx->priv = NULL, and returns 0 to avd_start_streaming(), which then
allows avd_h264_run() and avd_h264_done() to dereference a NULL h264_ctx.
Should ret be set to -ENOMEM before goto err_free_ctx?

[Severity: High]
In drivers/media/platform/apple/avd/avd-av1.c and avd-h264.c, can
userspace trigger out-of-bounds reads via unchecked reference indices?

In set_ref_hdr() (drivers/media/platform/apple/avd/avd-av1.c):

	for (i = 0; i < 6; i++) {
		for (j = i + 1; j < 7; j++) {
			if (frame->reference_frame_ts[frame->ref_frame_idx[i]] ==
			    frame->reference_frame_ts[frame->ref_frame_idx[j]]) {

Here frame->ref_frame_idx[] is an array of signed __s8 values from
userspace used directly to index the 8-element frame->reference_frame_ts[]
array without bounds checking. Also, in avd_av1_get_ref_buf():

	if (idx < 0 || idx >= V4L2_AV1_TOTAL_REFS_PER_FRAME ||
	    frame->ref_frame_idx[idx] >= ARRAY_SIZE(frame->reference_frame_ts))

Should idx be checked against V4L2_AV1_REFS_PER_FRAME (7, the size of
frame->ref_frame_idx[]) instead of V4L2_AV1_TOTAL_REFS_PER_FRAME (8), and
should frame->ref_frame_idx[idx] also be checked for < 0?

Similarly, in stream_slice() (drivers/media/platform/apple/avd/avd-h264.c):

		/* sl->ref_pic_list1[0].index < ARRAY_SIZE(decode->dpb) */
		/* bidirectional reference of previous mv */
		ref = avd_get_ref_buf(
			ctx, &dst->base.vb,
			decode->dpb[sl->ref_pic_list1[0].index].reference_ts);

Can sl->ref_pic_list1[0].index (an unvalidated __u8 from userspace) index
past the 16-element decode->dpb[] array when sl->slice_type is
V4L2_H264_SLICE_TYPE_B?

[Severity: High]
In drivers/media/platform/apple/avd/avd-v4l2.c, does calling VIDIOC_TRY_FMT
on the capture queue corrupt the active ctx->comp state?

avd_try_capture_fmt() calls avd_fill_decoded_pixfmt(ctx, pix_mp):

	if (is_interchange(pix_mp->pixelformat))
		pix_mp->plane_fmt[0].sizeimage = 0;
	ctx->comp.start_offset = pix_mp->plane_fmt[0].sizeimage;

	fill_comp(&ctx->comp, ctx->image_fmt, pix_mp->width, pix_mp->height);

Because avd_fill_decoded_pixfmt() writes directly to ctx->comp, a
VIDIOC_TRY_FMT ioctl will overwrite ctx->comp.start_offset,
ctx->comp.offsets, and ctx->comp.size, which avd_run_preamble() then uses
to compute DMA addresses for active capture buffers:

	run->comp_out = run->y_out + ctx->comp.start_offset;
	ctx->decomp = !is_interchange(ctx->decoded_fmt.fmt.pix_mp.pixelformat);

	dst = vb2_to_avd_decoded_buf(&run->bufs.dst->vb2_buf);
	memcpy(&dst->comp, &ctx->comp, sizeof(ctx->comp));

[Severity: Medium]
In stream_slice_mv() (drivers/media/platform/apple/avd/avd-hevc.c):

	if (ref_valid) {
		dma_addr_t mv_color_addr =
			vb2_dma_contig_plane_dma_addr(&ref->base.vb.vb2_buf,
						      0) +
			(ref->base.vb.planes[0].length -
			 mv_color_size(fmt_width(ctx), fmt_height(ctx)));
		pusha(mv_color_addr, "mv_colo", 0);
	}

When userspace queues a VB2_MEMORY_DMABUF capture buffer with plane length
0, ref->base.vb.planes[0].length remains 0 while the actual buffer size is
stored in ref->base.vb.vb2_buf.planes[0].length (which is what
avd_hevc_run_preamble() uses when computing run->addresses.mv_color).
Doesn't using ref->base.vb.planes[0].length here underflow the 32-bit
subtraction and produce an invalid DMA address?

[Severity: High]
With resets = <&ps_avd_sys> and the mbox0 interrupt wired up here, can
avd_watchdog_func() race with the threaded handler avd_irq_handler() in
drivers/media/platform/apple/avd/avd-drv.c?

In avd_watchdog_func():

	writel(0, avd->mbox + AVD_REG_MBOX_IRQ_ENABLE);
	ret = avd_reset(avd);
	if (ret)
		dev_err(avd->dev, "failed to reset: %d", ret);

	avd_job_finish(ctx, VB2_BUF_STATE_ERROR);

And in avd_irq_handler():

	status = readl(avd->mbox + AVD_REG_MBOX0_RETRIEVE);
	writel(AVD_MBOX0_NOT_EMPTY, avd->mbox + AVD_REG_MBOX_IRQ_CLR);
...
	/* if the watchdog_work has run the work has already been submitted */
	if (cancel_delayed_work(&ctx->watchdog_work))
		avd_job_finish(ctx, state);

If the mbox0 IRQ fires just as ctx->watchdog_work expires,
avd_watchdog_func() only clears AVD_REG_MBOX_IRQ_ENABLE in MMIO without
calling disable_irq() or synchronize_irq(). Can avd_irq_handler() execute
concurrently on another CPU and read/write avd->mbox while avd_reset() ->
reset_control_reset(avd->rstc) -> apple_pmgr_reset_assert() asserts
APPLE_PMGR_DEV_DISABLE and APPLE_PMGR_RESET on ps_avd_sys? Also, if
avd_watchdog_func() finishes the job and starts the next M2M job before
avd_irq_handler() reaches cancel_delayed_work(&ctx->watchdog_work), can
avd_irq_handler() cancel the new job's watchdog timer and call
avd_job_finish() a second time?

[Severity: Low]
Should "apple,t6030-dart" be documented in
Documentation/devicetree/bindings/iommu/apple,dart.yaml before adding it
here?

Currently, properties:compatible in apple,dart.yaml only permits:

  compatible:
    oneOf:

[Severity: Critical]
Enabling video-codec@30b070000 with compatible "apple,t8122-avd" exposes
the AV1 decoder path in drivers/media/platform/apple/avd/avd-av1.c via
avd_device_run() -> avd_av1_run(). Since neither validate_av1_frame() in
drivers/media/v4l2-core/v4l2-ctrls-core.c nor avd_av1_try_ctrl() validates
ref_frame_idx, primary_ref_frame, upscaled_width, frame_width_minus_1, or
frame_height_minus_1 from V4L2_CID_STATELESS_AV1_FRAME, can userspace
trigger out-of-bounds memory accesses and divide-by-zero errors here?

Specifically:

1. In set_ref_hdr() in drivers/media/platform/apple/avd/avd-av1.c:

	for (i = 0; i < 6; i++) {
		for (j = i + 1; j < 7; j++) {
			if (frame->reference_frame_ts[frame->ref_frame_idx[i]] ==
			    frame->reference_frame_ts[frame->ref_frame_idx[j]]) {
				ref_slots[j] = ref_slots[i];
				break;
			}
		}
	}

Since frame->ref_frame_idx[i] is an unvalidated __s8, can a negative value
or a value >= 8 read out of bounds of the 8-element
frame->reference_frame_ts[] array?

2. In avd_av1_get_ref_buf() in drivers/media/platform/apple/avd/avd-av1.c:

	if (idx < 0 || idx >= V4L2_AV1_TOTAL_REFS_PER_FRAME ||
	    frame->ref_frame_idx[idx] >= ARRAY_SIZE(frame->reference_frame_ts))
		ts = -1;
	else
		ts = frame->reference_frame_ts[frame->ref_frame_idx[idx]];

frame->ref_frame_idx has V4L2_AV1_REFS_PER_FRAME (7) elements, whereas
V4L2_AV1_TOTAL_REFS_PER_FRAME is 8. If avd_av1_set_prob() passes
run->frame->primary_ref_frame (which is only checked for == 7 rather than
>= V4L2_AV1_REFS_PER_FRAME), or if idx is 7, doesn't this read
frame->ref_frame_idx[7] out of bounds, or allow a negative
frame->ref_frame_idx[idx] to underflow frame->reference_frame_ts[]?

3. In set_header() -> calc_upscale() in
drivers/media/platform/apple/avd/avd-av1.c:

	downscaled_plane_w = AV1_DIV_ROUND_UP_POW2(frame_width, sub_x);
	upscaled_plane_w = AV1_DIV_ROUND_UP_POW2(upscaled_width, sub_x);
	*step_x = ((downscaled_plane_w << SUPERRES_SCALE_BITS) +
		   (upscaled_plane_w / 2)) /
		  upscaled_plane_w;

Can an unvalidated frame->upscaled_width == 0 cause upscaled_plane_w to be
0 and trigger a divide-by-zero? Similarly, in set_refs(), can
frame->frame_width_minus_1 == 0xffffffff or
frame->frame_height_minus_1 == 0xffffffff wrap width or height to 0 when
adding 1 and divide by zero?

4. In update_dec_buf_info() and avd_av1_set_prob() in
drivers/media/platform/apple/avd/avd-av1.c:

	memcpy(vb2_plane_vaddr(&dst->base.vb.vb2_buf, 0) +
		       AVD_AV1_CDFS_OFFSET(dst->base.vb.vb2_buf.planes[0].length,
					   dst->av1.color_size),
	       av1_ctx->bufs.probs.cpu, sizeof(struct avd_av1_cdfs));

dst->av1.color_size is calculated from frame_width_minus_1 + 1 and
frame_height_minus_1 + 1 without checking that they fit within the capture
format dimensions in ctx->decoded_fmt.fmt.pix_mp or
dst->base.vb.vb2_buf.planes[0].length. If dst->av1.color_size exceeds the
plane length, doesn't AVD_AV1_CDFS_OFFSET() underflow and cause memcpy() to
write before the start of the buffer?

[Severity: High]
Also in the H.264 decoder path enabled by this node (via
v4l2_m2m_request_queue() -> avd_device_run() -> avd_h264_run() in
drivers/media/platform/apple/avd/avd-h264.c), can slice reallocation and
error handling access memory out of bounds?

In avd_h264_realloc_slices():

	h264_ctx->alloc_slice_num = alloc_slice_num;
	memcpy(h264_ctx->slices, tmp,
	       sizeof(*h264_ctx->slices) * h264_ctx->slice_num);
	kfree(tmp);

	/* we could already have the correct size */
	if ((alloc_slice_num + 1) * sizeof(*job->segments) < job->buf.size)
		return 0;

	ret = avd_buf_alloc(ctx->dev, &tmp_buf,
			   (alloc_slice_num + 1) * sizeof(*job->segments));
	if (ret)
		return -ENOMEM;

	job->segments = tmp_buf.cpu;
	job->num_alloc = (alloc_slice_num + 1);
	memset(tmp_buf.cpu, 0, tmp_buf.size);
	memcpy(job->segments, job->buf.cpu,
	       sizeof(*job->segments) * (job->num + 1));

1. On the first slice of a frame, avd_init_job() allocates
job->num_alloc = h264_ctx->alloc_slice_num + 1 segments, and
avd_end_segment() increments job->num for the stream header and for each
slice. When h264_ctx->slice_num reaches h264_ctx->alloc_slice_num, job->num
is already equal to the old job->num_alloc (alloc_slice_num + 1). Doesn't
copying sizeof(*job->segments) * (job->num + 1) bytes read one
struct avd_segment past the end of job->buf.cpu?

2. Since h264_ctx->alloc_slice_num is updated before the early return and
before avd_buf_alloc(), if the early return is taken (without updating
job->num_alloc) or if avd_buf_alloc() fails with -ENOMEM, won't
h264_ctx->alloc_slice_num remain enlarged while job->segments and
job->num_alloc stay at their old capacity, causing subsequent slices to
skip reallocation and write out of bounds on job->segments?

3. In avd_h264_run(), avd_h264_realloc_slices() is only called when
ctx->job.segments is non-NULL, yet h264_ctx->slices[h264_ctx->slice_num] is
written and h264_ctx->slice_num is incremented before checking
is_new_frame(run.slice_params) and !ctx->job.segments:

	if (ctx->job.segments &&
	    h264_ctx->slice_num >= h264_ctx->alloc_slice_num) {
		ret = avd_h264_realloc_slices(ctx);
		if (ret)
			goto postamble;
	}

	h264_ctx->active_slice = &h264_ctx->slices[h264_ctx->slice_num];
	ret = avd_buf_alloc(ctx->dev, h264_ctx->active_slice,
			    vb2_get_plane_payload(&src->vb2_buf, 0));
	if (ret)
		goto postamble;

	memcpy(h264_ctx->active_slice->cpu, slice,
	       h264_ctx->active_slice->size);
	h264_ctx->slice_num++;

If userspace queues slices with first_mb_in_slice != 0 and
V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF set while ctx->job.segments is NULL,
avd_h264_run() returns -EINVAL and avd_h264_done() skips resetting
h264_ctx->slice_num because V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF is set. Can
repeatedly queueing such buffers increment h264_ctx->slice_num past
h264_ctx->alloc_slice_num without reallocating h264_ctx->slices[]? Also,
should avd_h264_stop() clear ctx->job.segments = NULL on streamoff?

[Severity: High]
In avd_queue_init() in drivers/media/platform/apple/avd/avd-drv.c, both
src_vq and dst_vq enable VB2_DMABUF with vb2_dma_contig_memops. Unlike
avd_h264_run(), which checks the return value of vb2_plane_vaddr() for
NULL, the VP9 and AV1 paths enabled by "apple,t8122-avd" do not check
vb2_plane_vaddr() before dereferencing it:

In avd_vp9_run() -> set_tiles() in
drivers/media/platform/apple/avd/avd-vp9.c:

	const u8 *data = vb2_plane_vaddr(&src->vb2_buf, 0);
	...
				tile_size = get_unaligned_be32(&data[offset]);

And in avd_av1_run() -> avd_av1_set_prob() in
drivers/media/platform/apple/avd/avd-av1.c:

		memcpy(av1_ctx->bufs.probs.cpu,
		       vb2_plane_vaddr(&ref->base.vb.vb2_buf, 0) +
			       AVD_AV1_CDFS_OFFSET(
				       ref->base.vb.vb2_buf.planes[0].length,
				       ref->av1.color_size),
		       sizeof(struct avd_av1_cdfs));
	}

	/*
	 * AVD writes nothing when DISABLE_FRAME_END_UPDATE_CDF is
	 * enabled
	 */
	memcpy(vb2_plane_vaddr(&dst->base.vb.vb2_buf, 0) +
		       AVD_AV1_CDFS_OFFSET(dst->base.vb.vb2_buf.planes[0].length,
					   dst->av1.color_size),
	       av1_ctx->bufs.probs.cpu, sizeof(struct avd_av1_cdfs));

If an imported DMABUF fails dma_buf_vmap_unlocked() in vb2_plane_vaddr()
and returns NULL, won't these dereference a NULL pointer + offset?

[Severity: High]
Finally, in drivers/media/platform/apple/avd/avd-drv.c (bound via this
video-codec@30b070000 node), there appear to be a few concurrency and
lifecycle issues:

1. In avd_watchdog_func():

	writel(0, avd->mbox + AVD_REG_MBOX_IRQ_ENABLE);
	ret = avd_reset(avd);
	if (ret)
		dev_err(avd->dev, "failed to reset: %d", ret);

	avd_job_finish(ctx, VB2_BUF_STATE_ERROR);

And in avd_irq_handler():

	static irqreturn_t avd_irq_handler(int irq, void *data)
	{
		struct avd_dev *avd = data;
		struct avd_ctx *ctx = v4l2_m2m_get_curr_priv(avd->m2m_dev);

Can avd_watchdog_func() race with a concurrently running or pending
threaded avd_irq_handler()? Without synchronizing the IRQ before calling
avd_reset() and avd_job_finish(), if avd_job_finish() starts the next
queued M2M job and re-arms watchdog_work, couldn't the in-flight
avd_irq_handler() look up the newly started job via
v4l2_m2m_get_curr_priv(avd->m2m_dev), cancel its watchdog, and prematurely
finish it?

2. In avd_probe(), devm_request_threaded_irq() registers avd_irq_handler()
before avd_v4l2_init() allocates avd->m2m_dev, and in avd_remove(),
avd_v4l2_cleanup() frees avd->m2m_dev via v4l2_m2m_release() before the
IRQ is freed. If an interrupt fires during probe or remove, won't
v4l2_m2m_get_curr_priv(avd->m2m_dev) in avd_irq_handler() dereference a
NULL or freed avd->m2m_dev?

3. In avd_boot():

	memcpy_toio(avd->code, avd->fw->data, avd->fw->size);

	writel_relaxed(AVD_MBOX_ENABLE, avd->mbox + AVD_REG_MBOX1_STATUS);
	writel_relaxed(AVD_MBOX_ENABLE, avd->mbox + AVD_REG_MBOX0_STATUS);
	writel_relaxed(AVD_MBOX0_NOT_EMPTY,
		       avd->mbox + AVD_REG_MBOX_IRQ_ENABLE);
	writel_relaxed(AVD_RUN_CTRL_UNK_RUN, avd->mbox + AVD_REG_RUN_CTRL);

	/* wait for cm3 to boot */
	ret = readl_poll_timeout(avd->mbox + AVD_REG_FLAG0_SET, val, val == 1,
				 10, 10000);
	if (ret)
		return ret;

	memcpy_fromio(version, avd->sram, sizeof(version));
	dev_info_once(avd->dev, "fw version: %s\n", version);

Should avd_boot() verify that avd->fw->size does not exceed the "code"
region size (0x10000 in this DT node) before memcpy_toio(), use writel()
instead of writel_relaxed() when writing AVD_RUN_CTRL_UNK_RUN so the
firmware copy is ordered before starting the coprocessor, and ensure
version is NUL-terminated before printing it with %s?

4. In avd_open():

	v4l2_fh_init(&ctx->fh, video_devdata(filp));

	ctx->fh.m2m_ctx = v4l2_m2m_ctx_init(avd->m2m_dev, ctx, avd_queue_init);
	if (IS_ERR(ctx->fh.m2m_ctx)) {
		ret = PTR_ERR(ctx->fh.m2m_ctx);
		goto err_free_ctx;
	}

	ret = avd_init_ctrls(ctx);
	if (ret)
		goto err_cleanup_m2m_ctx;

Should the err_cleanup_m2m_ctx and err_free_ctx error paths call
v4l2_fh_exit(&ctx->fh) before freeing ctx?

[Severity: Low]
Does the compatible string "apple,t6031-dart" need to be documented in
Documentation/devicetree/bindings/iommu/apple,dart.yaml?

Currently, the schema only permits:

  compatible:
    oneOf:
      - enum:
          - apple,t8103-dart
          - apple,t8103-usb4-dart
          - apple,t8110-dart
          - apple,t6000-dart
      - items:
          - const: apple,t6020-dart
          - const: apple,t8110-dart

Without an entry for "apple,t6031-dart", running dtbs_check on device trees
including t6031-dieX.dtsi will report a schema validation failure on
iommu@2cd010000.

[Severity: Medium]
Instantiating video-codec@2cd070000 binds the AVD driver introduced earlier
in this series (drivers/media/platform/apple/avd/). Looking at the driver
implementation that this node enables on t6031, are horizontal and vertical
subsampling divisors swapped in fill_comp()?

In drivers/media/platform/apple/avd/avd-drv.c:fill_comp():

	/* uv has 16x16 tiles and 8 bytes of metadata per tile */
	calc_tile_meta(width / info->vdiv, height / info->hdiv,
		       v4l2_format_info_bpp(info, 1), 16, 8, &uv,
		       &uv_meta);

When avd_open() or format/control ioctls (avd_s_output_fmt(),
avd_try_capture_fmt(), avd_s_capture_fmt(), avd_s_ctrl()) call
avd_fill_decoded_pixfmt() -> fill_comp() with a 4:2:2 format
(AVD_IMG_FMT_ANY, AVD_IMG_FMT_422_8BIT, or AVD_IMG_FMT_422_10BIT),
v4l2_format_info() returns hdiv = 2 and vdiv = 1.

Passing width / info->vdiv and height / info->hdiv divides the width by 1 and
the height by 2 instead of width / info->hdiv and height / info->vdiv. For
resolutions where DIV_ROUND_UP(width / 2, 16) * DIV_ROUND_UP(height, 16)
differs from DIV_ROUND_UP(width, 16) * DIV_ROUND_UP(height / 2, 16) (such as
720x1280), could this under-allocate uv, comp->size, and
pix_mp->plane_fmt[0].sizeimage, causing the hardware to DMA past the end of
the capture buffer when push_comp() programs comp->offsets?

[Severity: High]
Also in the H.264 decoder path enabled by this node, can
avd_h264_realloc_slices() read out of bounds from job->buf.cpu or leave
alloc_slice_num out of sync with job->segments?

In drivers/media/platform/apple/avd/avd-h264.c:avd_h264_run():

	if (ctx->job.segments &&
	    h264_ctx->slice_num >= h264_ctx->alloc_slice_num) {
		ret = avd_h264_realloc_slices(ctx);
		if (ret)
			goto postamble;
	}

On the first slice of a frame, avd_h264_run() calls avd_init_job() with
num_segments = h264_ctx->alloc_slice_num + 1, and calls avd_end_segment()
twice (for stream_hdr() and stream_slice()). Each subsequent slice increments
h264_ctx->slice_num and calls avd_end_segment() once, incrementing job->num.

When h264_ctx->slice_num reaches h264_ctx->alloc_slice_num, job->num is
already equal to the old alloc_slice_num + 1 (which equals job->num_alloc, the
full size of job->buf). In avd_h264_realloc_slices():

	h264_ctx->alloc_slice_num = alloc_slice_num;
	memcpy(h264_ctx->slices, tmp,
	       sizeof(*h264_ctx->slices) * h264_ctx->slice_num);
	kfree(tmp);

	/* we could already have the correct size */
	if ((alloc_slice_num + 1) * sizeof(*job->segments) < job->buf.size)
		return 0;

	ret = avd_buf_alloc(ctx->dev, &tmp_buf,
			   (alloc_slice_num + 1) * sizeof(*job->segments));
	if (ret)
		return -ENOMEM;

	job->segments = tmp_buf.cpu;
	job->num_alloc = (alloc_slice_num + 1);
	memset(tmp_buf.cpu, 0, tmp_buf.size);
	memcpy(job->segments, job->buf.cpu,
	       sizeof(*job->segments) * (job->num + 1));

Since job->buf only holds job->num elements at this point, doesn't copying
(job->num + 1) elements read one struct avd_segment past the end of
job->buf.cpu?

Furthermore, because h264_ctx->alloc_slice_num is updated before checking
job->buf.size and before avd_buf_alloc(), if the early return is taken
(without updating job->num_alloc) or if avd_buf_alloc() fails with -ENOMEM,
won't subsequent slices in the same frame see slice_num < alloc_slice_num,
skip reallocation, and write out of bounds into job->segments?

[Severity: Critical]
In drivers/media/platform/apple/avd/avd-hevc.c, can crafted V4L2 HEVC
stateless controls trigger out-of-bounds accesses and integer overflows during
avd_hevc_run()?

1. In avd_hevc_validate_pps() and compute_tiles_non_uniform():

static int avd_hevc_validate_pps(struct avd_ctx *ctx,
				 const struct v4l2_ctrl_hevc_pps *pps)
{
	if (pps->num_tile_columns_minus1 + 1 > HEVC_MAX_TILE_COLS ||
	    pps->num_tile_rows_minus1 + 1 > HEVC_MAX_TILE_ROWS)
		return -EINVAL;

	for (i = 0; i < pps->num_tile_columns_minus1; i++) {
		column_width[i] = MIN(pps->column_width_minus1[i] + 1,
				      pic_in_cts_width);
		sum += column_width[i];
	}
	column_width[i] = pic_in_cts_width - sum;

HEVC_MAX_TILE_COLS is 40 and HEVC_MAX_TILE_ROWS is 44, whereas struct
v4l2_ctrl_hevc_pps defines column_width_minus1[20] and row_height_minus1[22].
Won't compute_tiles_non_uniform() read past the end of column_width_minus1[]
and row_height_minus1[] when num_tile_columns_minus1 > 20 or
num_tile_rows_minus1 > 22?

In addition, if sum exceeds pic_in_cts_width (or pic_in_cts_height for rows),
pic_in_cts_width - sum underflows u16 column_width[i], causing compute_bd() to
produce col_bd[] / row_bd[] values larger than the picture CTB dimensions and
causing compute_tile_ids() to read ctb_addr_rs_to_ts[] and write tile_ids[]
out of bounds:

	for (j = 0, tile_idx = 0; j <= pps->num_tile_rows_minus1; j++)
		for (i = 0; i <= pps->num_tile_columns_minus1; i++, tile_idx++)
			for (y = row_bd[j]; y < row_bd[j + 1]; y++)
				for (x = col_bd[i]; x < col_bd[i + 1]; x++)
					tile_ids[ctb_addr_rs_to_ts
							 [y * pic_in_ctbs_width +
							  x]] = tile_idx;

2. In stream_slices() -> submit_slice_segment():

		if (pps->flags & V4L2_HEVC_PPS_FLAG_TILES_ENABLED)
			push(AVD_SL_DIM_END_ROW((hflip ? 4 : 0) |
						(vflip ? 8 : 0)) |
				     AVD_SL_DIM_END_COL(col) |
				     AVD_SL_DIM_END_Y(row_bd[row + 1] - 1) |
				     AVD_SL_DIM_END_X(col_bd[col + 1] - 1),
			     "cm3_set_ctb_xy");

stream_slices() increments pos for each segment with NEW_TILE_ID and computes
row = pos / num_cols without checking that row <= pps->num_tile_rows_minus1.
Can this read row_bd[row + 1] (and row_bd[row]) out of bounds?

3. In avd_hevc_validate_sps() and avd_hevc_compute_tiles(), are zero
pic_width_in_luma_samples / pic_height_in_luma_samples or large coding block
shift exponents (>= 31) rejected before computing max_cu_width = 1 << (...)
and dividing by max_cu_width?

4. In avd_hevc_run_preamble():

	for (i = 0; i < run->num_slices; i++)
		sum += (*run->sl)[i].num_entry_point_offsets;

	if (sum && sum != run->num_entry_point_offsets)
		return -EINVAL;

Since sum is a signed int and num_entry_point_offsets is u32, can sum overflow
and wrap to 0 (or a small value matching run->num_entry_point_offsets),
causing avd_init_job() to under-allocate ctx->job.segments and leading to
out-of-bounds accesses on run->entry_point_offsets in stream_slices() and
job->segments in avd_end_segment()?

[Severity: High]
In drivers/media/platform/apple/avd/avd-av1.c and avd-h264.c, could missing
validation on stateless AV1 and H.264 controls lead to out-of-bounds accesses
or divide-by-zero errors?

1. In drivers/media/platform/apple/avd/avd-av1.c:avd_av1_set_prob():

	memcpy(vb2_plane_vaddr(&dst->base.vb.vb2_buf, 0) +
		       AVD_AV1_CDFS_OFFSET(dst->base.vb.vb2_buf.planes[0].length,
					   dst->av1.color_size),
	       av1_ctx->bufs.probs.cpu, sizeof(struct avd_av1_cdfs));

Neither avd_av1_try_ctrl() nor avd_av1_run_preamble() checks that
frame->frame_width_minus_1 + 1 and frame->frame_height_minus_1 + 1 fit within
ctx->decoded_fmt.fmt.pix_mp.width and height. If userspace passes larger frame
dimensions, dst->av1.color_size can exceed planes[0].length, underflowing
AVD_AV1_CDFS_OFFSET() and writing sizeof(struct avd_av1_cdfs) bytes before
vb2_plane_vaddr(). Also, if frame_width_minus_1 or frame_height_minus_1 is
U32_MAX, width or height wraps to 0 in set_refs(), causing a division by zero.

2. In drivers/media/platform/apple/avd/avd-av1.c:set_ref_hdr():

	for (i = 0; i < 6; i++) {
		for (j = i + 1; j < 7; j++) {
			if (frame->reference_frame_ts[frame->ref_frame_idx[i]] ==
			    frame->reference_frame_ts[frame->ref_frame_idx[j]]) {

frame->ref_frame_idx[] contains __s8 values from userspace. Unlike
avd_av1_get_ref_buf(), set_ref_hdr() indexes the 8-element
frame->reference_frame_ts[] array without checking that ref_frame_idx[i] and
ref_frame_idx[j] are within 0..7.

3. In drivers/media/platform/apple/avd/avd-av1.c:calc_upscale():

	downscaled_plane_w = AV1_DIV_ROUND_UP_POW2(frame_width, sub_x);
	upscaled_plane_w = AV1_DIV_ROUND_UP_POW2(upscaled_width, sub_x);
	*step_x = ((downscaled_plane_w << SUPERRES_SCALE_BITS) +
		   (upscaled_plane_w / 2)) /
		  upscaled_plane_w;

calc_upscale() is called from set_header() without checking that
frame->upscaled_width is non-zero, which can divide by zero when
upscaled_plane_w is 0.

4. In drivers/media/platform/apple/avd/avd-av1.c:avd_av1_run_preamble():

	run->tile_group = ctrl->p_cur.p;

	if (run->frame->tile_info.tile_cols * run->frame->tile_info.tile_rows >
		ctrl->new_elems)
		return -EINVAL;

Since run->tile_group reads from ctrl->p_cur.p, should this check ctrl->elems
rather than ctrl->new_elems?

5. In drivers/media/platform/apple/avd/avd-h264.c:stream_slice():

		/* sl->ref_pic_list1[0].index < ARRAY_SIZE(decode->dpb) */
		/* bidirectional reference of previous mv */
		ref = avd_get_ref_buf(
			ctx, &dst->base.vb,
			decode->dpb[sl->ref_pic_list1[0].index].reference_ts);

sl->ref_pic_list1[0].index is an unvalidated u8 from userspace (v4l2-ctrls
only validates num_ref_idx_l1_active_minus1, not the index fields in
ref_pic_list1[]), so can this read past the 16-element decode->dpb[] array?
Similarly, should avd_h264_validate_sps() validate the SPS macroblock
dimensions against ctx->coded_fmt or ctx->decoded_fmt?

[Severity: Medium]
Finally, in drivers/media/platform/apple/avd/avd-drv.c, are there two small
issues in avd_boot() and avd_open()?

In avd_boot():

	memcpy_fromio(version, avd->sram, sizeof(version));
	dev_info_once(avd->dev, "fw version: %s\n", version);

version is a 64-byte stack array filled from avd->sram without ensuring NUL
termination; if SRAM does not contain a NUL byte in the first 64 bytes,
formatting with %s will read past the stack buffer. Should version be
explicitly NUL-terminated or printed with %.*s?

And in avd_open():

	v4l2_fh_init(&ctx->fh, video_devdata(filp));

	ctx->fh.m2m_ctx = v4l2_m2m_ctx_init(avd->m2m_dev, ctx, avd_queue_init);
	if (IS_ERR(ctx->fh.m2m_ctx)) {
		ret = PTR_ERR(ctx->fh.m2m_ctx);
		goto err_free_ctx;
	}

	ret = avd_init_ctrls(ctx);
	if (ret)
		goto err_cleanup_m2m_ctx;

	v4l2_fh_add(&ctx->fh, filp);

	return 0;

err_cleanup_m2m_ctx:
	v4l2_m2m_ctx_release(ctx->fh.m2m_ctx);

err_free_ctx:
	avd_buf_free(avd, &ctx->pipe_state);
	avd_buf_free(avd, &ctx->inst);
	kfree(ctx);

If v4l2_m2m_ctx_init() or avd_init_ctrls() fails after v4l2_fh_init(), should
err_free_ctx call v4l2_fh_exit(&ctx->fh) before freeing ctx?
