In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with

In mtk_jpeg_dec_device_run, if error happens in
mtk_jpeg_set_dec_dst, it will finally start the worker while
mark the job as finished by invoking v4l2_m2m_job_finish.
There are two methods to trigger the bug. If we remove the
module, it which will call mtk_jpeg_remove to make cleanup.
The possible sequence is as follows, which will cause a
use-after-free bug.
CPU0 CPU1
mtk_jpeg_dec_... |
start worker |
|mtk_jpeg_job_timeout_work
mtk_jpeg_remove |
v4l2_m2m_release |
kfree(m2m_dev); |
|
| v4l2_m2m_get_curr_priv
| m2m_dev->curr_ctx //use
If we close the file descriptor, which will call mtk_jpeg_release,
it will have a similar sequence.
Fix this bug by starting timeout worker only if started jpegdec worker
successfully. Then v4l2_m2m_job_finish will only be called in
either mtk_jpeg_job_timeout_work or mtk_jpeg_dec_device_run.

In the multi-core JPEG encoder/decoder setup, the driver for the
individual cores references the parent device's platform driver data.
However, in the parent driver, this is only set at the end of the probe
function, way later than devm_of_platform_populate(), which triggers
the probe of the cores. This causes a kernel splat in the sub-device
probe function.
Move platform_set_drvdata() to before devm_of_platform_populate() to
fix this.

Commit fe8a339783 ("media: mediatek: vcodec: Read HW active status
from syscon") allowed the driver to read the VDEC_SYS io space from a
syscon instead of from the reg property when reg-names are supplied.
However as part of that change, a smatch warning was introduced:
drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c:142 mtk_vcodec_get_reg_bases() error: buffer overflow 'mtk_dec_reg_names' 11 <= 11
With a correct Devicetree, that is, one that follows the dt-binding, it
wouldn't be possible to trigger such a buffer overflow. Even so, update
the range validation of the reg property, so that the smatch warning is
fixed and if an incorrect Devicetree is ever supplied the code errors
out instead of causing memory corruption.

If we encounter any error in the vdec_msg_queue_init() then we need
to set "msg_queue->wdma_addr.size = 0;". Normally, this is done
inside the vdec_msg_queue_deinit() function. However, if the
first call to allocate &msg_queue->wdma_addr fails, then the
vdec_msg_queue_deinit() function is a no-op. For that situation, just
set the size to zero explicitly and return.
There were two other error paths which did not clean up before returning.
Change those error paths to goto mem_alloc_err.

The "lat_buf->private_data" needs to be set to NULL to prevent a
double free. How this would happen is if vdec_msg_queue_init() failed
twice in a row and on the second time it failed earlier than on the
first time.
The vdec_msg_queue_init() function has a loop which does:
for (i = 0; i < NUM_BUFFER_COUNT; i++) {
Each iteration initializes one element in the msg_queue->lat_buf[] array
and then the clean up function vdec_msg_queue_deinit() frees each
element of the msg_queue->lat_buf[] array. This clean up code relies
on the assumption that every element is either initialized or zeroed.
Leaving a freed pointer which is non-zero breaks the assumption.

Remove the requirement of a VDEC_SYS reg iospace for both MT8173 and
MT8183. To achieve that, rely on a vdecsys syscon to be passed through
the DT, and use it to directly read the VDEC_HW_ACTIVE bit during IRQ
handling to check whether the HW is active. Also update the VP8 stateful
decoder to use the syscon, if present, for writes to VDEC_SYS.
The old behavior is still present when reg-names aren't supplied, as
to keep backward compatibility.

As part of that merge prepping Arm DT support 13 years ago, they

A follow-up patch moved it inside of an #ifdef, which caused more
warnings, and a third patch ended up adding even more #ifdefs. These
were all bogus, since the actual problem here is the incorrect use
of of_ptr(). Since the driver (like any other modern platform driver)
only works in combination with CONFIG_OF, there is no point in hiding
the reference, so just remove that along with all the pointless #ifdef
checks in the driver.
This improves build coverage and avoids running into the same problem
again when another part of the driver gets changed that relies on
the #ifdef blocks to be completely matched.

Since the LAT decoder works faster than its CORE, getting the trans
buffer may be done only after CORE finishes processing: avoid printing
an error if the decode function returns -EAGAIN, as this means that
the buffer from CORE is not yet available, but will be at a later time.
Also change the log level for calls to vdec_msg_queue_dqbuf() in H264
and VP9 LAT decoder drivers to avoid excessive logging.

This reverts commit cd61f3c679. That
commit's purpose was to prevent the padding from being decoded when
userspace didn't set a selection, relying on the default one.
However, as described in the Step 6 of the Initialization procedure for
the Memory-to-Memory Stateful Video Encoder Interface [1]:
"Set the visible resolution for the stream metadata via
VIDIOC_S_SELECTION() on the OUTPUT queue if it is desired to be
different than the full OUTPUT resolution."
And from the Note:
"To avoid encoding the padding, the client needs to explicitly configure
this selection target"
Hence the behavior in the original commit doesn't follow the interface
and needs to be reverted.
This fixes the following v4l2-compliance failure observed on
mt8192-asurada-spherion:
fail: v4l2-test-formats.cpp(924): sel.r.width != fmt.g_width()
test VIDIOC_S_FMT: FAIL
