* media: qcom: Clean up Kconfig dependenciesRobin Murphy2025-03-061-1/+1
| | | | | | | | | | | | Depending on IOMMU_DMA is suspicious, since the low-level DMA ops internals and MSI helpers is provides are not of interest to general drivers. In practice it mostly seems to be serving as a dependency on ARM64 here, so do that properly. The venus driver looks like it won't actually be useful at runtime without the IOMMU API, so add that too.

* media: venus: hfi: add check to handle incorrect queue sizeVikash Garodia2025-03-031-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | qsize represents size of shared queued between driver and video firmware. Firmware can modify this value to an invalid large value. In such situation, empty_space will be bigger than the space actually available. Since new_wr_idx is not checked, so the following code will result in an OOB write. ... qsize = qhdr->q_size if (wr_idx >= rd_idx) empty_space = qsize - (wr_idx - rd_idx) .... if (new_wr_idx < qsize) { memcpy(wr_ptr, packet, dwords << 2) --> OOB write Add check to ensure qsize is within the allocated size while reading and writing packets into the queue.

* media: venus: hfi_parser: refactor hfi packet parsing logicVikash Garodia2025-03-031-26/+72
| | | | | | | | | | | | | | | | words_count denotes the number of words in total payload, while data points to payload of various property within it. When words_count reaches last word, data can access memory beyond the total payload. This can lead to OOB access. With this patch, the utility api for handling individual properties now returns the size of data consumed. Accordingly remaining bytes are calculated before parsing the payload, thereby eliminates the OOB access possibilities.

In such case, if codecs_count can get incremented to value more than MAX_CODEC_NUM, there can be OOB access. Reset the count so that it always starts from beginning.

| | | | | | | | | | | | | | | | The Host firmware interface (HFI) is a well defined set of interfaces for the communication between the host driver and the firmware. The commands and responses are exchanged in form of packets. One or multiple packets are grouped under the packet header. Each packet has a packet type which describes the specific HFI and the payload, which holds the corresponding value for that HFI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a core state management for iris driver with the necessary queues needed for the host firmware communication. There are 3 types of queues: Command queue - driver to write any command to firmware. Message queue - firmware to send any response to the driver. Debug queue - for the firmware to write debug messages. Initialize and configure the shared queues during probe. Different states for core: IRIS_CORE_DEINIT - default state. IRIS_CORE_INIT - core state with core initialized. FW loaded and HW brought out of reset, shared queues established between host driver and firmware. IRIS_CORE_ERROR - error state. ----------- | V ----------- | DEINIT | ----------- ^ / \ / \ / \ / \ v v ----------- ----------. | INIT |-->| ERROR | ----------- ----------.
