2025-07-03media: qcom: camss: Power pipeline only when streamingRichard Acayan
The libcamera plugin for Pipewire may keep an open file descriptor to the video device, even while streaming. This simplifies its operation, as it only needs to keep track of a number instead of a file path. When the video device is open but not streaming, the pipeline can be powered off. Move the pipeline power management to the prepare_streaming and unprepare_streaming functions.

2025-07-03media: iris: Add codec specific check for VP9 decoder drain handlingDikshita Agarwal
Add a codec specific for the VP9 decoder to ensure that a non-null buffer is sent to the firmware during drain. The firmware enforces a check for VP9 decoder that the number of buffers queued and dequeued on the output plane should match. When a null buffer is sent, the firmware does not return a response for it, leading to a count mismatch and an assertion failure from the firmware.

2025-07-03media: iris: Remove redundant buffer count check in stream offDikshita Agarwal
Currently, the stream off process checks the count of buffers in v4l2_m2m_queues using v4l2_m2m_for_each_src_buf_safe and v4l2_m2m_for_each_dst_buf_safe APIs. If the count is non-zero, it returns an error. This check is redundant as the V4L2 framework already handles buffer management internally. Remove the unnecessary buffer count check in stream off, simplifying the process and relying on V4L2's internal mechanisms for buffer management.

2025-07-03media: iris: Track flush responses to prevent premature completionDikshita Agarwal
Currently, two types of flush commands are queued to the firmware, the first flush queued as part of sequence change, does not wait for a response, while the second flush queued as part of stop, expects a completion response before proceeding further. Due to timing issue, the flush response corresponding to the first command could arrive after the second flush is issued. This casuses the driver to incorrectly assume that the second flush has completed, leading to the premature signaling of flush_completion. To address this, introduce a counter to track the number of pending flush responses and signal flush completion only when all expected responses are received.

During reconfig, the firmware sends the resolution aligned to 8 bytes. If the driver sends the same resolution back to the firmware the resolution will be aligned to 16 bytes not 8. The alignment mismatch would then subsequently cause the firmware to send another redundant sequence change event. Fix this by not setting the resolution property during reconfig.

2025-07-03media: venus: Fix OOB read due to missing payload bound checkVedang Nagar
Currently, The event_seq_changed() handler processes a variable number of properties sent by the firmware. The number of properties is indicated by the firmware and used to iterate over the payload. However, the payload size is not being validated against the actual message length. This can lead to out-of-bounds memory access if the firmware provides a property count that exceeds the data available in the payload. Such a condition can result in kernel crashes or potential information leaks if memory beyond the buffer is accessed. Fix this by properly validating the remaining size of the payload before each property access and updating bounds accordingly as properties are parsed. This ensures that property parsing is safely bounded within the received message buffer and protects against malformed or malicious firmware behavior.
