Hans Verkuil 81b3fd0cb4 media: dvb-usb/dvb-usb-urb.c: initialize actlen to 0
commit 569bc8d6a6 upstream.

This fixes a syzbot failure since actlen could be uninitialized,
but it was still used.

Hans Verkuil f416aac94c media: gspca: zero usb_buf
commit de89d0864f upstream.

Allocate gspca_dev->usb_buf with kzalloc instead of kmalloc to
ensure it is property zeroed. This fixes various syzbot errors
about uninitialized data.

Philipp Zabel 03915a22e8 media: coda: fix deadlock between decoder picture run and start command
commit a3fd80198d upstream.

The BIT decoder picture run temporarily locks the bitstream mutex while
the coda device mutex is locked, to refill the bitstream ring buffer.
Consequently, the decoder start command, which locks both mutexes when
flushing the bitstream ring buffer, must lock the coda device mutex
first as well, to avoid an ABBA deadlock.

Janusz Krzysztofik 7ad319dd4d media: ov6650: Fix .get_fmt() V4L2_SUBDEV_FORMAT_TRY support
commit 39034bb0c2 upstream.

Commit da298c6d98 ("[media] v4l2: replace video op g_mbus_fmt by pad
op get_fmt") converted a former ov6650_g_fmt() video operation callback
to an ov6650_get_fmt() pad operation callback.  However, the converted
function disregards a format->which flag that pad operations should
obey and always returns active frame format settings.

That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with
-EINVAL, or providing the response from a pad config argument, likely
updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt().
Since implementation of the latter is trivial, go for it.

Janusz Krzysztofik 86c03858bf media: ov6650: Fix some format attributes not under control
commit 1c6a2b6309 upstream.

User arguments passed to .get/set_fmt() pad operation callbacks may
contain unsupported values.  The driver takes control over frame size
and pixel code as well as colorspace and field attributes but has never
cared for remainig format attributes, i.e., ycbcr_enc, quantization
and xfer_func, introduced by commit 11ff030c73 ("[media]
v4l2-mediabus: improve colorspace support").  Fix it.

Set up a static v4l2_mbus_framefmt structure with attributes
initialized to reasonable defaults and use it for updating content of
user provided arguments.  In case of V4L2_SUBDEV_FORMAT_ACTIVE,
postpone frame size update, now performed from inside ov6650_s_fmt()
helper, util the user argument is first updated in ov6650_set_fmt() with
default frame format content.  For V4L2_SUBDEV_FORMAT_TRY, don't copy
all attributes to pad config, only those handled by the driver, then
fill the response with the default frame format updated with resulting
pad config format code and frame size.

Hans Verkuil 80d9e63714 media: cec: check 'transmit_in_progress', not 'transmitting'
commit ac479b51f3 upstream.

Currently wait_event_interruptible_timeout is called in cec_thread_func()
when adap->transmitting is set. But if the adapter is unconfigured
while transmitting, then adap->transmitting is set to NULL. But the
hardware is still actually transmitting the message, and that's
indicated by adap->transmit_in_progress and we should wait until that
is finished or times out before transmitting new messages.

As the original commit says: adap->transmitting is the userspace view,
adap->transmit_in_progress reflects the hardware state.

However, if adap->transmitting is NULL and adap->transmit_in_progress
is true, then wait_event_interruptible is called (no timeout), which
can get stuck indefinitely if the CEC driver is flaky and never marks
the transmit-in-progress as 'done'.

So test against transmit_in_progress when deciding whether to use
the timeout variant or not, instead of testing against adap->transmitting.

This is caused by media_device_cleanup() which destroys
v4l2_dev->mdev->req_queue_mutex. But v4l2_release() tries to lock
that mutex after media_device_cleanup() is called.

By moving media_device_cleanup() to the video_device's release function it is
guaranteed that the mutex is valid whenever v4l2_release is called.

Pi-Hsun Shih aa32eb1a10 media: v4l2-ctrl: Lock main_hdl on operations of requests_queued.
[ Upstream commit df4a3e7f88 ]

There's a race condition between the list_del_init in the
v4l2_ctrl_request_complete, and the list_add_tail in the
v4l2_ctrl_request_queue, since they can be called in different thread
and the requests_queued list is not protected by a lock. This can lead
to that the v4l2_ctrl_handler is still in the requests_queued list while
the request_is_queued is already set to false, which would cause
use-after-free if the v4l2_ctrl_handler is later released.

Fix this by locking the ->lock of main_hdl (which is the owner of the
requests_queued list) when doing list operations on the
->requests_queued list.

Mike Isely 570cacc74e media: pvrusb2: Fix oops on tear-down when radio support is not present
[ Upstream commit 7f404ae9cf ]

In some device configurations there's no radio or radio support in the
driver.  That's OK, as the driver sets itself up accordingly.  However
on tear-down in these caes it's still trying to tear down radio
related context when there isn't anything there, leading to
dereferences through a null pointer and chaos follows.

How this bug survived unfixed for 11 years in the pvrusb2 driver is a
mystery to me.

When driver is built as module and probe during insmod is deferred
because of sensor subdevs, there is NULL pointer deference because
mdev is cleaned up and then access it from v4l2_device_unregister().
Fix the wrong mdev and v4l2 dev order in error path of probe.

This fixes below null pointer deference:

This is caused by media_device_cleanup() which destroys
v4l2_dev->mdev->req_queue_mutex. But v4l2_release() tries to lock
that mutex after media_device_cleanup() is called.

By moving media_device_cleanup() to the v4l2_device's release function it is
guaranteed that the mutex is valid whenever v4l2_release is called.

Janusz Krzysztofik 08ba731d67 media: ov6650: Fix stored frame interval not in sync with hardware
[ Upstream commit 57822068dd ]

The driver stores a frame interval value supposed to be in line with
hardware state in a device private structure.  Since the driver initial
submission, the respective field of the structure has never been
initialised on device probe.  Moreover, if updated from
.s_frame_interval(), a new value is stored before it is applied on
hardware.  If an error occurs during device update, the stored value
may no longer reflect hardware state and consecutive calls to
.g_frame_interval() may return incorrect information.

Assuming a failed update of the device means its actual state hasn't
changed, update the frame interval field of the device private
structure with a new value only after it is successfully applied on
hardware so it always reflects actual hardware state to the extent
possible.  Also, initialise the field with hardware default frame
interval on device probe.

The default pixel format was setup as pointing to a specific offset in

above commid-id)

So instead of hard-coding an offset which might change over time we need
to use a lookup helper instead so we know the default will always be what
we intended.

Benoit Parrot e2898767d6 media: ti-vpe: vpe: fix a v4l2-compliance warning about invalid pixel format
[ Upstream commit 06bec72b25 ]

v4l2-compliance warns with this message:

   warn: v4l2-test-formats.cpp(717): \
 	TRY_FMT cannot handle an invalid pixelformat.
   warn: v4l2-test-formats.cpp(718): \
 	This may or may not be a problem. For more information see:
   warn: v4l2-test-formats.cpp(719): \
 	http://www.mail-archive.com/linux-media@vger.kernel.org/msg56550.html
	...
   test VIDIOC_TRY_FMT: FAIL

We need to make sure that the returns a valid pixel format in all
instance. Based on the v4l2 framework convention drivers must return a
valid pixel format when the requested pixel format is either invalid or
not supported.

Benoit Parrot 33ec87948e media: ti-vpe: vpe: Fix Motion Vector vpdma stride
[ Upstream commit 102af9b992 ]

commit 3dc2046ca7 ("[media] media: ti-vpe: vpe: allow use of user
specified stride") and commit da4414eaed ("[media] media: ti-vpe: vpdma:
add support for user specified stride") resulted in the Motion Vector
stride to be the same as the image stride.

This caused memory corruption in the output image as mentioned in
commit 00db969964 ("[media] media: ti-vpe: vpe: Fix line stride
for output motion vector").

Christophe JAILLET 8120c9b469 media: cx88: Fix some error handling path in 'cx8800_initdev()'
[ Upstream commit e1444e9b04 ]

A call to 'pci_disable_device()' is missing in the error handling path.
In some cases, a call to 'free_irq()' may also be missing.

Reorder the error handling path, add some new labels and fix the 2 issues
mentionned above.

This way, the error handling path in more in line with 'cx8800_finidev()'
(i.e. the remove function)

Neil Armstrong d3cac7d030 media: meson/ao-cec: move cec_notifier_cec_adap_register after hw setup
[ Upstream commit 3e84a18a25 ]

When probed after the HDMI notifier, calling cec_notifier_cec_adap_register()
calls the enable() adapter callback, but the HW is not yet set up.

Moving cec_notifier_cec_adap_register() right before cec_register_adapter()
fixes the following crash:

If usb_set_interface() failed, iface->cur_altsetting will
not be assigned and it will be used in flexcop_usb_transfer_init()
It may lead a NULL pointer dereference.

Check usb_set_interface() return value in flexcop_usb_init()
and return failed to avoid using this NULL pointer.

Shuah Khan f780e4ace1 media: vimc: Fix gpf in rmmod path when stream is active
[ Upstream commit d7fb5c361c ]

If vimc module is removed while streaming is in progress, sensor subdev
unregister runs into general protection fault when it tries to unregister
media entities. This is a common subdev problem related to releasing
pads from v4l2_device_unregister_subdev() before calling unregister.
Unregister references pads during unregistering subdev.

The sd release handler is the right place for releasing all sd resources
including pads. The release handlers currently release all resources
except the pads.

Fix v4l2_device_unregister_subdev() not release pads and release pads
from the sd_int_op release handlers.
