8bde543d2a media: dvb-net: fix OOB access in ULE extension header tables
commit 24d8771272 upstream.

The ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables
in handle_one_ule_extension() are declared with 255 elements (valid
indices 0-254), but the index htype is derived from network-controlled
data as (ule_sndu_type & 0x00FF), giving a range of 0-255. When
htype equals 255, an out-of-bounds read occurs on the function pointer
table, and the OOB value may be called as a function pointer.

Add a bounds check on htype against the array size before either table
is accessed. Out-of-range values now cause the SNDU to be discarded.

cfd9464202 media: dvb-core: fix wrong reinitialization of ringbuffer on reopen
commit bfbc0b5b32 upstream.

dvb_dvr_open() calls dvb_ringbuffer_init() when a new reader opens the
DVR device.  dvb_ringbuffer_init() calls init_waitqueue_head(), which
reinitializes the waitqueue list head to empty.

Since dmxdev->dvr_buffer.queue is a shared waitqueue (all opens of the
same DVR device share it), this orphans any existing waitqueue entries
from io_uring poll or epoll, leaving them with stale prev/next pointers
while the list head is reset to {self, self}.

The waitqueue and spinlock in dvr_buffer are already properly
initialized once in dvb_dmxdev_init().  The open path only needs to
reset the buffer data pointer, size, and read/write positions.

Replace the dvb_ringbuffer_init() call in dvb_dvr_open() with direct
assignment of data/size and a call to dvb_ringbuffer_reset(), which
properly resets pread, pwrite, and error with correct memory ordering
without touching the waitqueue or spinlock.

[ Upstream commit bbef55f414 ]

Two platform-data fields for SM8750 were missed:

  - get_vpu_buffer_size = iris_vpu33_buf_size
    Without this, the driver fails to allocate the required internal
    buffers, leading to basic decode/encode failures during session
    bring-up.

  - max_core_mbps = ((7680 * 4320) / 256) * 60

    v4l2-compliance for encoder fails.

448a7662ae media: iris: remove v4l2_m2m_ioctl_{de,en}coder_cmd API usage during STOP handling
[ Upstream commit 8fc707d13d ]

Currently v4l2_m2m_ioctl_{de,enc}coder_cmd is being invoked during STOP
command handling. However, this is not required as the iris driver has
its own drain and stop handling mechanism in place.

Using the m2m command API in this context leads to incorrect behavior,
where the LAST flag is prematurely attached to a capture buffer,
when there are no buffers in m2m source queue. But, in this scenario
even though the source buffers are returned to client, hardware might
still need to process the pending capture buffers.

Attaching LAST flag prematurely can result in the capture buffer being
removed from the destination queue before the hardware has finished
processing it, causing issues when the buffer is eventually returned by
the hardware.

To prevent this, remove the m2m API usage in stop handling.

77f69aa4de media: iris: Prevent output buffer queuing before stream-on completes
[ Upstream commit 2c73cfd0cf ]

During normal playback, stream-on for input is followed by output, and
only after input stream-on does actual streaming begin. However, when
gst-play performs a seek, both input and output streams are stopped,
and on restart, output stream-on occurs first. At this point, firmware
has not yet started streaming. Queuing output buffers before the firmware
begins streaming causes it to process buffers in an invalid state, leading
to an error response. These buffers are returned to the driver as errors,
forcing the driver into an error state and stopping playback.

Fix this by deferring output buffer queuing until stream-on completes.
Input buffers can still be queued before stream-on as required.

45b30f65fe media: iris: Add buffer to list only after successful allocation
[ Upstream commit 2d0bbd982d ]

Move `list_add_tail()` to after `dma_alloc_attrs()` succeeds when creating
internal buffers. Previously, the buffer was enqueued in `buffers->list`
before the DMA allocation. If the allocation failed, the function returned
`-ENOMEM` while leaving a partially initialized buffer in the list, which
could lead to inconsistent state and potential leaks.

By adding the buffer to the list only after `dma_alloc_attrs()` succeeds,
we ensure the list contains only valid, fully initialized buffers.

[ Upstream commit 4980721cb9 ]

According to 4.5.1.5 of the M2M stateful decoder UAPI documentation,
providing the width and the height to S_FMT is "required only if it
cannot be parsed from the stream", otherwise they can be left as 0
and the S_FMT implementation is expected to return a valid placeholder
resolution that would let REQBUFS succeed.

iris was missing the fallback, so clients like rpi-ffmpeg wouldn't work.
Fix by adding an explicit fallback to defaults.

0cd7ca8e96 media: iris: Fix ffmpeg corrupted frame error
[ Upstream commit 89f7cf3590 ]

When the ffmpeg decoder is running, the driver receives the
V4L2_BUF_FLAG_KEYFRAME flag in the input buffer. The driver then forwards
this flag information to the firmware. The firmware, in turn, copies the
input buffer flags directly into the output buffer flags. Upon receiving
the output buffer from the firmware, the driver observes that the buffer
contains the HFI_BUFFERFLAG_DATACORRUPT flag. The root cause is that both
V4L2_BUF_FLAG_KEYFRAME and HFI_BUFFERFLAG_DATACORRUPT are the same value.
As a result, the driver incorrectly interprets the output frame as
corrupted, even though the frame is actually valid. This misinterpretation
causes the driver to report an error and skip good frames, leading to
missing frames in the final video output and triggering ffmpeg's "corrupt
decoded frame" error.

To resolve this issue, the input buffer flags should not be sent to the
firmware during decoding, since the firmware does not require this
information.

[ Upstream commit 370e19042f ]

This reverts commit ad699fa78b.

Revert the check that skipped stop_streaming when the instance was in
IRIS_INST_ERROR, as it caused multiple regressions:

1. Buffers were not returned to vb2 when the instance was already in
   error state, triggering warnings in the vb2 core because buffer
   completion was skipped.

2. If a session failed early (e.g. unsupported configuration), the
   instance transitioned to IRIS_INST_ERROR. When userspace attempted
   to stop streaming for cleanup, stop_streaming was skipped due to the
   added check, preventing proper teardown and leaving the firmware
   in an inconsistent state.

f3bf86dec1 media: venus: vdec: restrict EOS addr quirk to IRIS2 only
[ Upstream commit 63c072e293 ]

On SM8250 (IRIS2) with firmware older than 1.0.087, the firmware could
not handle a dummy device address for EOS buffers, so a NULL device
address is sent instead. The existing check used IS_V6() alongside a
firmware version gate:

    if (IS_V6(core) && is_fw_rev_or_older(core, 1, 0, 87))
        fdata.device_addr = 0;
    else
	fdata.device_addr = 0xdeadb000;

However, SC7280 which is also V6, uses a firmware string of the form
"1.0.<commit-hash>", which the version parser translates to 1.0.0. This
unintentionally satisfies the `is_fw_rev_or_older(..., 1, 0, 87)`
condition on SC7280. Combined with IS_V6() matching there as well, the
quirk is incorrectly applied to SC7280, causing VP9 decode failures.

Constrain the check to IRIS2 (SM8250) only, which is the only platform
that needed this quirk, by replacing IS_V6() with IS_IRIS2(). This
restores correct behavior on SC7280 (no forced NULL EOS buffer address).

vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop
bound and passes the index to vfe_isr_reg_update(). However,
vfe->line[] array is defined with VFE_LINE_NUM_MAX(4):

    struct vfe_line line[VFE_LINE_NUM_MAX];

When index is 4, 5, 6, the access to vfe->line[line_id] exceeds
the array bounds and resulting in out-of-bounds memory access.

Fix this by using separate loops for output lines and write masters.

A analogue maximum gain of 0xffff / 65525 seems unlikely and testing
indeed shows that the gain control wraps-around at 16383, so set the
maximum gain to 0x3fff / 16383.

The minimum gain of 0x100 is correct. Setting bits 8-11 to 0x0 results
in the same gain values as setting these bits to 0x1, with bits 0-7
still increasing the gain when going from 0x000 - 0x0ff in the exact
same range as when going from 0x100 - 0x1ff.

8df26a7649 media: i2c: ov01a10: Fix the horizontal flip control
[ Upstream commit ada20c3db0 ]

During sensor calibration I noticed that with the hflip control set
to false/disabled the image was mirrored.

So it seems that the horizontal flip control is inverted and needs to
be set to 1 to not flip (just like the similar problem recently fixed
on the ov08x40 sensor).

Invert the hflip control to fix the sensor mirroring by default.

As the comment above the newly added OV01A10_MEDIA_BUS_FMT define explains
the control being inverted also means that the native Bayer-order of
the sensor actually is GBRG not BGGR, but so as to not break userspace
the Bayer-order is kept at BGGR.

Add proper ERR_PTR checking and return the error to prevent
dereferencing an invalid pointer.

fe1c50fadc media: amphion: Drop min_queued_buffers assignment
[ Upstream commit 5633ec763a ]

The min_queued_buffers field controls when start_streaming() is called
by the vb2 core (it delays the callback until at least N buffers are
queued). Setting it to 1 affects the timing of start_streaming(), which
breaks the seek flow in decoder scenarios and causes test failures.

The current driver implementation does not rely on this minimum buffer
requirement and handles streaming start correctly with the default
value of 0, so remove these assignments.

adae1932f0 media: verisilicon: AV1: Fix tx mode bit setting
[ Upstream commit cb3f945c01 ]

AV1 specification describes 3 possibles tx modes: 4x4 only, largest and
select. The hardware allows 5 possibles tx modes: 4x4 only, 8x8, 16x16,
32x32 and select. Since the both aren't exactly matching we need to add
a mapping function to set the correct mode on hardware.

[ Upstream commit e0f99b810e ]

If all the fields of the CDEF parameters are zero (which is the default),
then av1_enable_cdef register needs to be unset
(despite the V4L2_AV1_SEQUENCE_FLAG_ENABLE_CDEF possibly being set).
