commit 47bb117911b051bbc90764a8bff96543cbd2005f upstream.
When initially testing the Camera Terminal Descriptor wTerminalType
field (buffer[4]), no mask is used. Later in the function, the MSB is
overloaded to store the descriptor subtype, and so a mask of 0x7fff
is used to check the type.
If a descriptor is specially crafted to set this overloaded bit in the
original wTerminalType field, the initial type check will fail (falling
through, without adjusting the buffer size), but the later type checks
will pass, assuming the buffer has been made suitably large, causing an
overflow.
Avoid this problem by checking for the MSB in the wTerminalType field.
If the bit is set, assume the descriptor is bad, and abort parsing it.

[ Upstream commit 75fa6e4f83a0923fe753827d354998d448b4fd6a ]
Add support for the third loop filter mode
V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY,
and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and
V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls.
The filter offset controls are signed values in the -6 to 6 range and
are stored into the slice header fields slice_alpha_c0_offset_div2 and
slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are
double their value, in range of -12 to 12.
Rename variables to more closely match the nomenclature in the H.264
specification.

[ Upstream commit 2912289a518077ddb8214e05336700148e97e235 ]
The v4l2_dv_timings_cap struct is used to do sanity checks when setting and
enumerating DV timings, ensuring that only valid timings as per the HW
capabilities are allowed.
However, many drivers just filled in 0 for the minimum width, height or
pixelclock frequency. This can cause timings with e.g. 0 as width and height
to be accepted, which will in turn lead to a potential division by zero.
Fill in proper values are minimum boundaries. 640x350 was chosen since it is
the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest
pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the
v4l2-dv-timings.h header).

[ Upstream commit c764da98a600a4b068d25c77164f092f159cecec ]
The video device release() callback for video-i2c driver frees the whole
struct video_i2c_data. If there is no user left for the video device
when video_unregister_device() is called, the release callback is executed.
However, in video_i2c_remove() some fields (v4l2_dev, lock, and queue_lock)
in struct video_i2c_data are still accessed after video_unregister_device()
is called.
This fixes the use after free by moving the code from video_i2c_remove()
to the release() callback.

[ Upstream commit 10e1fdb95809ed21406f53b5b4f064673a1b9ceb ]
Currently, disconnecting a USB webcam while it is in use prints out a
number of warnings, such as:
WARNING: CPU: 2 PID: 3118 at /build/linux-ezBi1T/linux-4.8.0/fs/sysfs/group.c:237 sysfs_remove_group+0x8b/0x90
sysfs group ffffffffa7cd0780 not found for kobject 'event13'
This has been noticed before. [0]
This is because of the order in which things are torn down.
If there are no streams active during a USB disconnect:
- uvc_disconnect() is invoked via device_del() through the bus
notifier mechanism.
- this calls uvc_unregister_video().
- uvc_unregister_video() unregisters the video device for each
stream,
- because there are no streams open, it calls uvc_delete()
- uvc_delete() calls uvc_status_cleanup(), which cleans up the status
input device.
- uvc_delete() calls media_device_unregister(), which cleans up the
media device
- uvc_delete(), uvc_unregister_video() and uvc_disconnect() all
return, and we end up back in device_del().
- device_del() then cleans up the sysfs folder for the camera with
dpm_sysfs_remove(). Because uvc_status_cleanup() and
media_device_unregister() have already been called, this all works
nicely.
If, on the other hand, there *are* streams active during a USB disconnect:
- uvc_disconnect() is invoked
- this calls uvc_unregister_video()
- uvc_unregister_video() unregisters the video device for each
stream,
- uvc_unregister_video() and uvc_disconnect() return, and we end up
back in device_del().
- device_del() then cleans up the sysfs folder for the camera with
dpm_sysfs_remove(). Because the status input device and the media
device are children of the USB device, this also deletes their
sysfs folders.
- Sometime later, the final stream is closed, invoking uvc_release().
- uvc_release() calls uvc_delete()
- uvc_delete() calls uvc_status_cleanup(), which cleans up the status
input device. Because the sysfs directory has already been removed,
this causes a WARNing.
- uvc_delete() calls media_device_unregister(), which cleans up the
media device. Because the sysfs directory has already been removed,
this causes another WARNing.
To fix this, we need to make sure the devices are always unregistered
before the end of uvc_disconnect(). To this, move the unregistration
into the disconnect path:
- split uvc_status_cleanup() into two parts, one on disconnect that
unregisters and one on delete that frees.
- move v4l2_device_unregister() and media_device_unregister() into
the disconnect path.

commit cd26d1c4d1bc947b56ae404998ae2276df7b39b7 upstream.
If a filehandle is dup()ped, then it is possible to close it from one fd
and call mmap from the other. This creates a race condition in vb2_mmap
where it is using queue data that __vb2_queue_free (called from close())
is in the process of releasing.
By moving up the mutex_lock(mmap_lock) in vb2_mmap this race is avoided
since __vb2_queue_free is called with the same mutex locked. So vb2_mmap
now reads consistent buffer data.

kthread_run returns an error pointer, but elsewhere in the code
dev->kthread_vid_cap/out is checked against NULL.
If kthread_run returns an error, then set the pointer to NULL.
I chose this method over changing all kthread_vid_cap/out tests

imx274_read_reg() takes a u8 pointer ("reg") and casts it to pass it
to regmap_read(), which takes an unsigned int pointer. This results in

commit ac791f19a273a7fe254a7596f193af6534582a9f upstream.
If the tx_ignore_nack_until_eom error injection was activated,
then tx_nacked was never set instead of setting it when the last
byte of the message was transmitted.
As a result the transmit was marked as OK, when it should have
been NACKed.
Modify the condition so that it always sets tx_nacked when the
last byte of the message was transmitted.

commit 32804fcb612bf867034a093f459415e485cf044b upstream.
I noticed that repeatedly running 'cec-ctl --playback' would occasionally
select 'Playback Device 2' instead of 'Playback Device 1', even though there
were no other Playback devices in the HDMI topology. This happened both with
'real' hardware and with the vivid CEC emulation, suggesting that this was an
issue in the core code that claims a logical address.
What 'cec-ctl --playback' does is to first clear all existing logical addresses,
and immediately after that configure the new desired device type.
The core code will poll the logical addresses trying to find a free address.
When found it will issue a few standard messages as per the CEC spec and return.
Those messages are queued up and will be transmitted asynchronously.
What happens is that if you run two 'cec-ctl --playback' commands in quick
succession, there is still a message of the first cec-ctl command being transmitted
when you reconfigure the adapter again in the second cec-ctl command.
When the logical addresses are cleared, then all information about outstanding
transmits inside the CEC core is also cleared, and the core is no longer aware
that there is still a transmit in flight.
When the hardware finishes the transmit it calls transmit_done and the CEC core
thinks it is actually in response of a POLL messages that is trying to find a
free logical address. The result of all this is that the core thinks that the
logical address for Playback Device 1 is in use, when it is really an earlier
transmit that ended.
The main transmit thread looks at adap->transmitting to check if a transmit
is in progress, but that is set to NULL when the adapter is unconfigured.
adap->transmitting represents the view of userspace, not that of the hardware.
So when unconfiguring the adapter the message is marked aborted from the point
of view of userspace, but seen from the PoV of the hardware it is still ongoing.
So introduce a new bool transmit_in_progress that represents the hardware state
and use that instead of adap->transmitting. Now the CEC core waits until the
hardware finishes the transmit before starting a new transmit.

to suit connected devices. In doing a call to usb_free_urb is made and
invertedly frees the buffers.

commit 04990215dec43c424daff00d1f622167b8aafd1f upstream.
vb2_start_streaming() already rolls back the buffers, so there is no
need to call __vb2_queue_cancel(). Especially since __vb2_queue_cancel()
does too much, such as zeroing the q->queued_count value, causing vb2
to think that no buffers have been queued.
It appears that this call to __vb2_queue_cancel() is a left-over from
before commit b3379c6201bb3.

commit 3d8e450f517cdb33da77827ec75929354753e9c0 upstream.
Tuners should report frequencies in Hz. That works fine on most
drivers, but, in the case of dvb-pll, some settings are for
satellite tuners, while others are for terrestrial/cable ones.
The code was trying to solve it at probing time, but that doesn't
work, as, when _attach is called, the delivery system may be wrong.
Fix it by ensuring that all frequencies are in Hz at the per-tuner
max/min values.
While here, add a debug message, as this would help to debug any
issues there.

However, the code doesn't check if there were errors other than OK or NACK,

Instead check for such errors and retry the poll. And if the problem persists

commit bad1774ed41e98a43074e50e7d5ac9e1e848d99a upstream.
As of: commit 476dec012f4c ("media: ov5640: Add horizontal and vertical
totals") the timings parameters gets programmed separately from the
static register values array.
When changing capture mode, the vertical and horizontal totals gets
inspected by the set_mode_exposure_calc() functions, and only later
programmed with the new values. This means exposure, light banding
filter and shutter gain are calculated using the previous timings, and
are thus not correct.
Fix this by programming timings right after the static register value
table has been sent to the sensor in the ov5640_load_regs() function.

commit aa4bb8b8838ffcc776a79f49a4d7476b82405349 upstream.
Rework the MIPI interface startup sequence with the following changes:
- Remove MIPI bus initialization from the initial settings blob
- At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in
LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode.
- At s_stream time enable/disable the MIPI interface output.
- Restore default settings at set_power(0) time.
Before this commit the sensor MIPI interface was initialized with settings
that require a start/stop sequence at power-up time in order to force lanes
into LP11 state, as they were initialized in LP00 when in 'sleep mode',
which is assumed to be the sensor manual definition for the D-PHY defined
stop mode.
The stream start/stop was performed by enabling disabling clock gating,
and had the side effect to change the lanes sleep mode configuration when
stream was stopped.
Clock gating/ungating:
- ret = ov5640_mod_reg(sensor, OV5640_REG_MIPI_CTRL00, BIT(5),
- on ? 0 : BIT(5));
- if (ret)
Set lanes in LP11 when in 'sleep mode':
- ret = ov5640_write_reg(sensor, OV5640_REG_PAD_OUTPUT00,
- on ? 0x00 : 0x70);
This commit fixes an issue reported by Jagan Teki on i.MX6 platforms that
prevents the host interface from powering up correctly:
https://lkml.org/lkml/2018/6/1/38
It also improves MIPI capture operations stability on my testing platform
where MIPI capture often failed and returned all-purple frames.

commit 92539d3eda2c090b382699bbb896d4b54e9bdece upstream.
Patch ad608fbcf166 changed how events were subscribed to address an issue
elsewhere. As a side effect of that change, the "add" callback was called
before the event subscription was added to the list of subscribed events,
causing the first event queued by the add callback (and possibly other
events arriving soon afterwards) to be lost.
Fix this by adding the subscription to the list before calling the "add"
callback, and clean up afterwards if that fails.
Fixes: ad608fbcf166 ("media: v4l: event: Prevent freeing event subscriptions while accessed")

[ Upstream commit 985cdcb08a0488558d1005139596b64d73bee267 ]
Mode setting depends on last mode set, in particular
because of exposure calculation when downscale mode
change between subsampling and scaling.
At stream on the last mode was wrongly set to current mode,
so no change was detected and exposure calculation
was not made, fix this.

fixes: 6949d864776e ("media: ov5640: do not change mode if format or frame interval is unchanged").
Symptom was fuzzy image because of JPEG default format
not being changed according to new format selected, fix this.
Init sequence initialises format to YUV422 UYVY but
sensor->fmt initial value was set to JPEG, fix this.

[ Upstream commit bd24db04101f45a9c1d874fe21b0c7eab7bcadec ]
The driver ignored the width alignment which exists due to the UYVY
colorspace format. Fix the width alignment and make use of the the
provided v4l2 helper function to set the width, height and all
alignments in one.

[ Upstream commit 1f32061e843205f6fe8404d5100d5adcec334e75 ]
On a decoder instance, after the profile has been parsed from the stream
__v4l2_ctrl_s_ctrl() is called to notify userspace about changes in the
read-only profile control. This ends up calling back into the CODA driver
where a missing check on the s_ctrl caused the profile information that has
just been parsed from the stream to be overwritten with the default
baseline profile.
Later on the driver fails to enable frame reordering, based on the wrong
profile information.

altera_hw_filt_init() which calls append_internal() assumes
that the node was successfully linked in while in fact it can
silently fail. So the call-site needs to set return to -ENOMEM

commit db0340182444612bcadb98bdec22f651aa42266c upstream.
The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.
The two old defines referring to ADOBERGB in the public API are
put under #ifndef __KERNEL__ and a comment mentions that they are
deprecated.
