commit 17e7f1b515803e1a79b246688aacbddd2e34165d upstream.
This solves this bug:
https://bugzilla.kernel.org/show_bug.cgi?id=73361
The problem is that when you quit tvtime it calls STREAMOFF, but then it queues a
bunch of buffers for no good reason before closing the file descriptor.
In the past closing the fd would free the vb queue since that was part of the file
handle struct. Since that was moved to the global struct that no longer happened.
This wouldn't be a problem, but the extra QBUF calls that tvtime does meant that
the buffer list in videobuf (q->stream) contained buffers, so REQBUFS would fail
with -EBUSY.
The solution is to init the list head explicitly when releasing the file
descriptor and to not free the video resource when calling streamoff.
The real fix will hopefully go into kernel 3.16 when the vb2 conversion is
merged. Basically the saa7134 driver with the old videobuf is so full of holes it
ain't funny anymore, so consider this a band-aid for kernels 3.14 and 15.

commit 3b35fc81e7ec552147a4fd843d0da0bbbe4ef253 upstream.
timestamps in v4l2 buffers returned to userspace are updated in
uvc_video_clock_update() which uses timestamps fetched from
uvc_video_clock_decode() by calling unconditionally ktime_get_ts().
Hence setting the module clock param to realtime has no effect before
this patch.
This has been tested with ffmpeg:
ffmpeg -y -f v4l2 -input_format yuyv422 -video_size 640x480 -framerate 30 -i /dev/video0 \
-f alsa -acodec pcm_s16le -ar 16000 -ac 1 -i default \
-c:v libx264 -preset ultrafast \
-c:a libfdk_aac \
out.mkv
and inspecting the v4l2 input starting timestamp.

commit 85ac1a1772bb41da895bad83a81f6a62c8f293f6 upstream.
Currently stk1160_read_reg() uses a stack-allocated char to get the
read control value. This is wrong because usb_control_msg() requires
a kmalloc-ed buffer.
This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive
the read value.
While here, let's remove the urb_buf array which was meant for a similar
purpose, but never really used.

commit 97d9d23dda6f37d90aefeec4ed619d52df525382 upstream.
If a struct contains 64-bit fields, it is aligned on 64-bit boundaries
within containing structs in 64-bit compilations. This is the case with
struct v4l2_window, which contains pointers and is embedded into struct
v4l2_format, and that one is embedded into struct v4l2_create_buffers.
Unlike some other structs, used as a part of the kernel ABI as ioctl()
arguments, that are packed, these structs aren't packed. This isn't a
problem per se, but the ioctl-compat code for VIDIOC_CREATE_BUFS contains
a bug, that triggers in such 64-bit builds. That code wrongly assumes,
that in struct v4l2_create_buffers, struct v4l2_format immediately follows
the __u32 memory field, which in fact isn't the case. This bug wasn't
visible until now, because until recently hardly any applications used
this ioctl() and mostly embedded 32-bit only drivers implemented it. This
is changing now with addition of this ioctl() to some USB drivers, e.g.
UVC. This patch fixes the bug by copying parts of struct
v4l2_create_buffers separately.

commit cfece5857ca51d1dcdb157017aba226f594e9dcf upstream.
Commit 75e2bdad8901a0b599e01a96229be922eef1e488 "ov7670: allow
configuration of image size, clock speed, and I/O method" uses a wrong

unchecked value from user-space, which can cause access to unmapped
memory in the kernel, triggered by a normal desktop user with rights to

commit 8272d0a0c0d374a01721e579df6e8add5577132b upstream.
Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.
Adding min delay prevents crashing the frontend on continuous
transponder scans. Other dvb_frontend_tune_settings remain as default.
This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.

commit b1e43f232698274871e1358c276d7b0242a7d607 upstream.
The UVC specification uses alternate setting selection to notify devices
of stream start/stop. This breaks when using bulk-based devices, as the
video streaming interface has a single alternate setting in that case,
making video stream start and video stream stop events to appear
identical to the device. Bulk-based devices are thus not well supported
by UVC.
The webcam built in the Asus Zenbook UX302LA ignores the set interface
request and will keep the video stream enabled when the driver tries to
stop it. If USB autosuspend is enabled the device will then be suspended
and will crash, requiring a cold reboot.
USB trace capture showed that Windows sends a CLEAR_FEATURE(HALT)
request to the bulk endpoint when stopping the stream instead of
selecting alternate setting 0. The camera then behaves correctly, and
thus seems to require that behaviour.
Replace selection of alternate setting 0 with clearing of the endpoint
halt feature at video stream stop for bulk-based devices. Let's refrain
from blaming Microsoft this time, as it's not clear whether this
Windows-specific but USB-compliant behaviour was specifically developed
to handle bulkd-based UVC devices, or if the camera just took advantage
of it.

This patch adds a test preventing streamon() if there is no buffer
ready.
Without this patch, a user could call streamon() before
preparing any buffer. This leads to a situation where if he calls
close() before calling streamoff() the device is kept streaming.

This reverts commit a242f426108c284049a69710f871cc9f11b13e61.
That commit actually caused deadlocks, rather then fixing them.
If ext_lock is set to NULL (otherwise videobuf_queue_lock doesn't do
anything), then you get this deadlock:
The driver's mmap function calls videobuf_mmap_mapper which calls
videobuf_queue_lock on q. videobuf_mmap_mapper calls __videobuf_mmap_mapper,
__videobuf_mmap_mapper calls videobuf_vm_open and videobuf_vm_open
calls videobuf_queue_lock on q (introduced by above patch): deadlocked.
This affects drivers using dma-contig and dma-vmalloc. Only dma-sg is
not affected since it doesn't call videobuf_vm_open from __videobuf_mmap_mapper.
Most drivers these days have a non-NULL ext_lock. Those that still use
NULL there are all fairly obscure drivers, which is why this hasn't been
seen earlier.
Since everything worked perfectly fine for many years I prefer to just
revert this patch rather than trying to fix it. videobuf is quite fragile
and I rather not touch it too much. Work is (slowly) progressing to move
everything over to vb2 or at the very least use non-NULL ext_lock in
videobuf.

Using variable length array in s5k5baf_write_arr_seq caused
an implicit assumption that i2c sequences should be short.
The patch rewrites the function so it can handle sequences
of any length and does not use variable length array.

Pull media updates from Mauro Carvalho Chehab:
- a new jpeg codec driver for Samsung Exynos (jpeg-hw-exynos4)
- a new dvb frontend for ds2103 chipset (m88ds2103)
- a new sensor driver for Samsung S5K5BAF UXGA (s5k5baf)
- new drivers for R-Car VSP1
- a new radio driver: radio-raremono
- a new tuner driver for ts2022 chipset (m88ts2022)
- the analog part of em28xx is now a separate module that only
load/runs if the device is not a pure digital TV device
- added a staging driver for bcm2048 radio devices
- the omap 2 video driver (omap24xx) was moved to staging. This driver
is for an old hardware and uses a deprecated Kernel internal API. If
nobody cares enough to fix it, it would be removed on a couple Kernel
releases
- the sn9c102 driver was moved to staging. This driver was replaced by
gspca, and disabled on some distros, as almost all devices are known
to work properly with gspca. It should be removed from kernel on a
couple Kernel releases
- lots of driver fixes, improvements and cleanups

The side effect of commit 1056e4388b045 ("v4l2-dev: Fix race condition on
__video_register_device") is the increased number of index value assigned
on video_device registration. Before that commit video_devices were
numbered from 0, after it, the indexes starts from 1, because get_index()
always count the device, which is being registered. Some device drivers
rely on video_device index number for internal purposes, i.e. s5p-mfc
driver stopped working after that patch. This patch restores the old method
of numbering the video_device indexes.

Pull networking updates from David Miller:
1) BPF debugger and asm tool by Daniel Borkmann.
2) Speed up create/bind in AF_PACKET, also from Daniel Borkmann.
3) Correct reciprocal_divide and update users, from Hannes Frederic
Sowa and Daniel Borkmann.
4) Currently we only have a "set" operation for the hw timestamp socket
ioctl, add a "get" operation to match. From Ben Hutchings.
5) Add better trace events for debugging driver datapath problems, also
from Ben Hutchings.
6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we
have a small send and a previous packet is already in the qdisc or
device queue, defer until TX completion or we get more data.
7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko.
8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel
Borkmann.
9) Share IP header compression code between Bluetooth and IEEE802154
layers, from Jukka Rissanen.
10) Fix ipv6 router reachability probing, from Jiri Benc.
11) Allow packets to be captured on macvtap devices, from Vlad Yasevich.
12) Support tunneling in GRO layer, from Jerry Chu.
13) Allow bonding to be configured fully using netlink, from Scott
Feldman.
14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can
already get the TCI. From Atzm Watanabe.
15) New "Heavy Hitter" qdisc, from Terry Lam.
16) Significantly improve the IPSEC support in pktgen, from Fan Du.
17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom
Herbert.
18) Add Proportional Integral Enhanced packet scheduler, from Vijay
Subramanian.
19) Allow openvswitch to mmap'd netlink, from Thomas Graf.
20) Key TCP metrics blobs also by source address, not just destination
address. From Christoph Paasch.
21) Support 10G in generic phylib. From Andy Fleming.
22) Try to short-circuit GRO flow compares using device provided RX
hash, if provided. From Tom Herbert.
The wireless and netfilter folks have been busy little bees too.

Pull clk framework changes from Mike Turquette:
"The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions
of existing drivers to the common-clock Device Tree binding, and a few
non-critical fixes to the framework.
Due to an entirely unnecessary cyclical dependency with the arm-soc
tree this pull request is broken into two pieces. The second piece
will be sent out after arm-soc sends you the pull request that merged
in core support for the HiSilicon 3620 platform. That same pull
request from arm-soc depends on this pull request to merge in those
HiSilicon bits without causing build failures"

Before changeset d8b4b5822f51e, the remote controller device numbers
were released when the device were unregistered. That helped to maintain
some sanity, as, when USB devices are replugged, the remote controller
would get the same number.
Restore the same behaviour.

Some of the SOCs hold the IRB IP in softreset state by default.
For this IP to work driver needs to bring it out of softreset.
This patch adds support to reset the IP via reset framework.
Without this patch the driver can not work with SoCs which holds the IP
in softreset.
