There is a wrong comparison of the total size of the loaded firmware css->fw->size with the size of a pointer to struct imgu_fw_header. Turn binary_header into a flexible-array member[1][2], use the struct_size() helper and fix the wrong size comparison. Notice that the loaded firmware needs to contain at least one 'struct imgu_fw_info' item in the binary_header[] array. It's also worth mentioning that "css->fw->size < struct_size(css->fwp, binary_header, 1)" with binary_header declared as a flexible-array member is equivalent to "css->fw->size < sizeof(struct imgu_fw_header)" with binary_header declared as a one-element array (as in the original code). The replacement of the one-element array with a flexible-array member also helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

At the moment of enabling irq handling: 1922 ret = devm_request_threaded_irq(&pdev->dev, irq, dcmi_irq_callback, 1923 dcmi_irq_thread, IRQF_ONESHOT, 1924 dev_name(&pdev->dev), dcmi); there is still uninitialized field sd_format of struct stm32_dcmi *dcmi. If an interrupt occurs in the interval between the installation of the interrupt handler and the initialization of this field, NULL pointer dereference happens. This field is dereferenced in the handler function without any check: 457 if (dcmi->sd_format->fourcc == V4L2_PIX_FMT_JPEG && 458 dcmi->misr & IT_FRAME) { The patch moves interrupt handler installation after initialization of the sd_format field that happens in dcmi_graph_notify_complete() via dcmi_set_default_fmt().

There were several issues with handling errors in lm3554_probe(): - Probe did not set the error code when v4l2_ctrl_handler_init() failed. - It intermixed gotos for handling errors of v4l2_ctrl_handler_init() and media_entity_pads_init(). - It did not set the error code for failures of v4l2_ctrl_new_custom(). - Probe did not free resources in case of failures of atomisp_register_i2c_module(). The patch fixes all these issues. Found by Linux Driver Verification project (linuxtesting.org). Link: https://lore.kernel.org/linux-media/20210810162943.19852-1-novikov@ispras.ruSigned-off-by:

The interrupt handling should be related to the firmware version. If the driver matches an old firmware, then the driver should not handle interrupt such as i2c or dma, otherwise it will cause some errors.

Add Mediatek's non-compressed 8 bit block video mode. This format is produced by the MT8183 codec and can be converted to a non-proprietary format by the MDP3 component. Signed-off-by:

Add support for decoder firmware version 2, which makes the kernel responsible for managing the VSI context and is used for stateless codecs. Signed-off-by:

Firmwares for decoders newer than MT8173 will include an ABI version number in their initialization ack message. Add the capacity to manage it and make initialization fail if the firmware ABI is of a version that we don't support. For MT8173, this ABI version field does not exist ; thus ignore it on this chip. There should only be one firmware version available for it anyway. Signed-off-by:

We are planning to add support for stateless decoders to this driver. Part of the driver will be shared between stateful and stateless codecs, but a few ops need to be specialized for both. Extract the stateful part of the driver and move it into its own file, accessible through ops that the common driver parts can call. This patch only moves code around and introduces a set of abstractions ; the behavior of the driver should not be changed in any way. Changes to code styling has been done to accommodate 'checkpatch.pl --strict'. [acourbot: refactor, cleanup and split] [tzungbi: fix errors from 'checkpatch.pl --strict'] Signed-off-by:

The V4L2 encoder specification requires encoders to support the V4L2_ENC_CMD_START and V4L2_ENC_CMD_STOP commands. Add support for these to the mtk-vcodec encoder by reusing the same flush buffer as used by the decoder driver.

The flush buffer is a special buffer that tells the decoder driver to send an empty CAPTURE frame to the client with V4L2_BUF_FLAG_LAST set. We need similar functionality for the encoder ; however currently the flush buffer depends on decoder-specific structures and thus cannot be reused with the encoder. Fix this by testing for this buffer by its VB2 address, and not through a dedicated flag stored in a higher-level decoder structure. This also allows us to remove said flag and simplify the code a bit. Since the flush buffer should never be used in the stateless decoder, also add safeguards to check against it. Signed-off-by:

Calling S_FMT or TRY_FMT on the OUTPUT queue should adjust the resolution to the limits supported by the hardware. Until now this was only done on the CAPTURE queue, which could make clients believe that unsupported resolutions can be used when they set the coded size on the OUTPUT queue. In the case of the stateless decoder, the problem was even bigger since subsequently calling G_FMT on the CAPTURE queue would result in the unclamped resolution being returned, further inducing the client into error.

ttusb_dec_send_command() invokes mutex_lock_interruptible() that can fail but then it releases the non-acquired mutex. The patch fixes that. Found by Linux Driver Verification project (linuxtesting.org). Fixes: dba328ba ("media: ttusb-dec: cleanup an error handling logic") Signed-off-by:

Currently the null pointer check on dvb_spi->vcc_supply is inverted and this leads to only null values of the dvb_spi->vcc_supply being passed to the call of regulator_disable causing null pointer dereferences. Fix this by only calling regulator_disable if dvb_spi->vcc_supply is not null.
