Ang Way Chuang 29e1fa3565 dvb-core: Fix DoS bug in ULE decapsulation code that can be triggered by an invalid Payload Pointer
ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
has a bug that causes endless loop when Payload Pointer of MPEG2-TS
frame is 182 or 183.  Anyone who sends malicious MPEG2-TS frame will
cause the receiver of ULE SNDU to go into endless loop.

This patch was generated and tested against linux-2.6.32.9 and should
apply cleanly to linux-2.6.33 as well because there was only one typo
fix to dvb_net.c since v2.6.32.

This bug was brought to you by modern day Santa Claus who decided to
shower the satellite dish at Keio University with heavy snow causing
huge burst of errors.  We, receiver end, received Santa Claus's gift in
the form of kernel bug.

Care has been taken not to introduce more bug by fixing this bug, but
please scrutinize the code for I always produces buggy code.

Linus Torvalds 9e3bd91908 b43: fall back gracefully to PIO mode after fatal DMA errors
This makes the b43 driver just automatically fall back to PIO mode when
DMA doesn't work.

The driver already told the user to do it, so rather than have the user
reload the module with a new flag, just make the driver do it
automatically. We keep the message as an indication that something is
wrong, but now just automatically fall back to the hopefully working PIO
case.

Sebastian Ott b4563e891a [S390] cio: wait for channel report
To fetch a pending channel report word (crw) we use a kernel
thread which triggers stcrw and sleeps on a semaphore. The s390
machine check handler uses crw_handle_channel_report to handle
one crw if needed.

This patch replaces the semaphore with a waitqueue (to block the
kernel thread) and an atomic_t (to count the number of pending
requests).

By this we achieve the ability to force this thread to check for
a pending crw (independent on when it is triggered by the machine
check handler) and wait for this action to finish.

Alan Stern 6d19c009cc USB: implement non-tree resume ordering constraints for PCI host controllers
This patch (as1331) adds non-tree ordering constraints needed for
proper resume of PCI USB host controllers from hibernation.  The main
issue is that non-high-speed devices must not be resumed before the
high-speed root hub, because it is the ehci_bus_resume() routine which
takes care of handing the device connection over to the companion
controller.  If the device resume is attempted before the handover
then the device won't be found and it will be treated as though it had
disconnected.

The patch adds a new field to the usb_bus structure; for each
full/low-speed bus this field will contain a pointer to the companion
high-speed bus (if one exists).  It is used during normal device
resume; if the hs_companion pointer isn't NULL then we wait for the
root-hub device on the hs_companion bus.

A secondary issue is that an EHCI controlller shouldn't be resumed
before any of its companions.  On some machines I have observed
handovers failing if the companion controller is reinitialized after
the handover.  Thus, the EHCI resume routine must wait for the
companion controllers to be resumed.

The patch also fixes a small bug in usb_hcd_pci_probe(); an error path
jumps to the wrong label, causing a memory leak.

Rafael J. Wysocki f8824cee40 PM: Allow device drivers to use dpm_wait()
There are some dependencies between devices (in particular, between
EHCI USB controllers and their OHCI/UHCI siblings) which are not
reflected by the structure of the device tree.  With synchronous
suspend and resume these dependencies are taken into accout
automatically, because the devices in question are always registered
in the right order, but to meet these constraints with asynchronous
suspend and resume the drivers of these devices will need to use
dpm_wait() in their suspend/resume routines, so introduce a helper
function allowing them to do that.

Rafael J. Wysocki 97df8c1299 PM: Start asynchronous resume threads upfront
It has been shown by testing that total device resume time can be
reduced significantly (by as much as 50% or more) if the async
threads executing some devices' resume routines are all started
before the main resume thread starts to handle the "synchronous"
devices.

This is a consequence of the fact that the slowest devices tend to be
located at the end of dpm_list, so their resume routines are started
very late.  Consequently, they have to wait for all the preceding
"synchronous" devices before their resume routines can be started
by the main resume thread, even if they are "asynchronous".  By
starting their async threads upfront we effectively move those
devices towards the beginning of dpm_list, without breaking their
ordering with respect to their parents and children.  As a result,
their resume routines are started much earlier and we are able to
save much more device resume time this way.

Rafael J. Wysocki 5af84b8270 PM: Asynchronous suspend and resume of devices
Theoretically, the total time of system sleep transitions (suspend
to RAM, hibernation) can be reduced by running suspend and resume
callbacks of device drivers in parallel with each other.  However,
there are dependencies between devices such that we're not allowed
to suspend the parent of a device before suspending the device
itself.  Analogously, we're not allowed to resume a device before
resuming its parent.

The most straightforward way to take these dependencies into accout
is to start the async threads used for suspending and resuming
devices at the core level, so that async_schedule() is called for
each suspend and resume callback supposed to be executed
asynchronously.

For this purpose, introduce a new device flag, power.async_suspend,
used to mark the devices whose suspend and resume callbacks are to be
executed asynchronously (ie. in parallel with the main suspend/resume
thread and possibly in parallel with each other) and helper function
device_enable_async_suspend() allowing one to set power.async_suspend
for given device (power.async_suspend is unset by default for all
devices).  For each device with the power.async_suspend flag set the
PM core will use async_schedule() to execute its suspend and resume
callbacks.

The async threads started for different devices as a result of
calling async_schedule() are synchronized with each other and with
the main suspend/resume thread with the help of completions, in the
following way:
(1) There is a completion, power.completion, for each device object.
(2) Each device's completion is reset before calling async_schedule()
    for the device or, in the case of devices with the
    power.async_suspend flags unset, before executing the device's
    suspend and resume callbacks.
(3) During suspend, right before running the bus type, device type
    and device class suspend callbacks for the device, the PM core
    waits for the completions of all the device's children to be
    completed.
(4) During resume, right before running the bus type, device type and
    device class resume callbacks for the device, the PM core waits
    for the completion of the device's parent to be completed.
(5) The PM core completes power.completion for each device right

Hans de Goede 26984b0995 V4L/DVB: gscpa_sonixb: Differentiate between sensors with a coarse and fine expo ctrl
Some sensors only allow controlling the exposure by changing the clockdiv,
which means that exposure takes pretty large jumps (for example when going
from a div of 1 to 2, the exposure doubles). Use 2 different entries in
the controls array for these 2 different types of exposure (always
disabling one), and;

Add a new autogain algorithm for the coarse exposure case, which normally
changes the gain setting, only touching the exposure setting if the desired
luminance cannot be reached with gain, and after an exposure change once more
first tries gain, etc. Thus avoiding exposure changes, and the resulting
oscilation because of the huge steps these exposure controls take.

This is a slightly modified version of Eric Anderson's original patch
for the Sony Giga Pocket board.  It has been updated to apply to the
latest ivtv driver version by Hans Verkuil <hverkuil@xs4all.nl> and
Andy Walls <awalls@radix.net>.  Also Andy Walls modified the patch to
use a new Sony BTF-Pnx01Z tuner entry based on Eric Anderson's experimental
findings for the bandswitch.

>From Eric Anderson's original email:

1. The tuner on the card doesn't seem to match any standard
ones. I modified an existing tuner entry. Ideally a new tuner
entry should be created. (The only difference from the one I
modified is that the low-to-mid range frequency cut-off is
slightly different, as are the bit config settings.)

2. It wasn't obvious how to choose a second audio input other
than using "radio" as an option. Basically there's two GPIO
audio inputs. Using radio allowed me to avoid major restructuring
to the code. (perhaps other cards don't have this often...)

3. It's not clear that there's a mute setting that works. Not
sure why.

4. I haven't had a chance to test the two Svideo inputs. I set
them to COMPOSITE1 and SVIDEO2, but I'm not sure those are the
correct settings. The standard composite video inputs seem to work.

Hmm, that code is a remnant from older revisions of this driver. Unfortunately,
when I compiled this driver before creating my pull request I forgot to turn on
the CONFIG_VIDEO_ADV_DEBUG option and so I never saw it.

Also fixed the g_register function: it never returned a register
value in the original code.

Antonio Ospite 6b727c68ea pxa_camera: remove init() callback
pxa_camera init() callback is sometimes abused to setup MFP for PXA CIF, or
even to request GPIOs to be used by the camera *sensor*. These initializations
can be performed statically in machine init functions.

The current semantics for this init() callback is ambiguous anyways, it is
invoked in pxa_camera_activate(), hence at device node open, but its users use
it like a generic initialization to be done at module init time (configure
MFP, request GPIOs for *sensor* control).

source and shutdown button probably could be mapped to something
better.

Adds digital and analogue tv support for Dikom DK300 hybrid usb card.

Not working: remote controller

To be done: it seems that with the proposed patch the digital demodulator
remains activated if the tuner is switched from digital to analogue mode.

Workaround is to unplug and replug the device when switching from digital to
analogue. If someone can explain how to verify the gpio settings using the
usbsnoop, the above issue perhaps can be resolved.

Klaas de Waal f0289efa19 V4L/DVB: dst: fixes for DVB-C Twinhan VP2031
Remove check  "state->dst_type == DST_DTYPE_IS_CABLE"  in function
dst_get_tuna (around line 1352) to select the correct checksum
computation

Fill in the .caps field in struct dst_dvbc_ops (around line 1824) with
all the supported QAM modulation methods to match the capabilities of
the card as implemented in function dst_set_modulation (around line
502). Note that beginning with linux kernel version 2.6.32 the
modulation method is checked (by function
dvb_frontend_check_parameters in file
drivers/media/dvb/dvb-core/dvb_frontend.c) and thus tuning fails if
you use a modulation method that is not present in the .caps field.

This patch has been tested on a Twinhan VP2031A DVB-C card with the
2.6.32.2 kernel.

When capturing NTSC, the saa7134 can capture 720x480.

While doing Laserdisc captures using this card, I noticed that right side

even though in Windows XP it is 720x480. This results in no cropping
and the same results as in Windows.

Arnaud Patard 22c859faf5 V4L/DVB: Fix VIDIOC_QBUF compat ioctl32
When using VIDIOC_QBUF with memory type set to V4L2_MEMORY_MMAP, the
v4l2_buffer buffer gets unmodified on drivers like uvc (well, only
bytesused field is modified). Then some apps like gstreamer are reusing
the same buffer later to call munmap (eg passing the buffer "length"
field as 2nd parameter of munmap).

It's working fine on full 32bits but on 32bits systems with 64bit
kernel, the get_v4l2_buffer32() doesn't copy length/m.offset values and
then copy garbage to userspace in put_v4l2_buffer32().

This has for consequence things like that in the libv4l2 logs:

libv4l2: v4l2 unknown munmap 0x2e2b0000, -2145144908
libv4l2: v4l2 unknown munmap 0x2e530000, -2145144908

The buffer are not unmap'ed and then if the application close and open
again the device, it won't work and logs will show something like:

libv4l2: error setting pixformat: Device or resource busy

The easy solution is to read length and m.offset in get_v4l2_buffer32().

Stefan Richter 6385c5bf98 V4L/DVB: firedtv: remove check for interrupting signal
FCP transactions as well as CMP transactions were serialized with
mutex_lock_interruptible.  It is extremely unlikly though that a signal
will arrive while a concurrent process holds the mutex.  And even if one
does, the duration of a transaction is reasonably short (1.2 seconds if
all retries time out, usually much shorter).

Hence simplify the code to plain mutex_lock.

Stefan Richter 3fb80ef3bc V4L/DVB: firedtv: do not DMA-map stack addresses
This is a portability fix and reduces stack usage.

The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt.  Convert the two cases of on-stack packet
payload buffers in firedtv (payload of write requests in avc_write and
of lock requests in cmp_lock) to slab-allocated memory.

We use the 512 bytes sized FCP frame buffer in struct firedtv for this
purpose.  Previously it held only incoming FCP responses, now it holds
pending FCP requests and is then overwriten by an FCP response from the
tuner subunit.  Ditto for CMP lock requests and responses.  Accesses to
the payload buffer are serialized by fdtv->avc_mutex.

As a welcome side effect, stack usage of the AV/C transaction functions
is reduced by 512 bytes.

Alas, avc_register_remote_control() is a special case:  It previously
did not wait for a response.  To fit better in with the other FCP
transactions, let it wait for an interim response.

Muralidharan Karicheri 8d1b5946bf V4L/DVB: vpfe-capture: converting dm644x ccdc driver to a platform driver
1) clocks are configured using generic clock names
2) converting the driver to a platform driver
3) cleanup - consolidate all static variables inside a structure, ccdc_cfg

The ccdc driver now uses generic names for clocks - master and slave. On individual platforms
these clocks will inherit from the platform specific clock. This will allow re-use of
the driver for the same IP across different SoCs.

Martin Dauskardt <martin.dauskardt@gmx.de> has done extensive testing on what
values can be used and and concluded that only 300 ms total is required to
avoid bad video effects such as occasional black screen and short sync
disturbances.  Furthermore he determined how this 300 ms was split between
the two msleep()s did matter very much, so he suggested 150ms/150ms as one
acceptable alternative that is implemented here.

Andy Walls 3ccc646b56 V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny audio
This change attempts to fix the ivtv tinny audio problem by keeping digitizer
to encoder audio clocks running, while disabling the video clocks as needed to
avoid unpredictable PCI bus hangs.

To accomplish this, for the cx25840 module enabling of audio streaming had
to be separated from enabling video streaming, requiring an additional
v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers.

The cx231xx and cx23885 driver use the cx25840 module for affecting only
video on s_stream calls, so those drivers needed no change.

The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI
bus hang, so the cx18 driver did not need corresponding changes.

CX2341[56] based cards that are not using the CX2584x family of chips
do not seem to be affected by the tinny audio problem, and this change should
not affect how they are configured. It will delay their first capture by
starting by another 300 msec though.

Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and
Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and
investigation of this problem will hopefully fix this problem once and for all
for many ivtv users.

Ian Armstrong b6e436b263 V4L/DVB: ivtv: Fix race condition for queued udma transfers
There are several DMA related interrupts which wake up the dma_waitq. The udma
routines use this queue while they wait for their transfer to complete. When
woken, the udma routine will check the IVTV_F_I_UDMA_PENDING & IVTV_F_I_UDMA
flags to see if the transfer is still queued or has finished. However, a small
window exists between the IVTV_F_I_UDMA_PENDING flag being cleared and the
IVTV_F_I_UDMA flag being set. Given that the completion of an unrelated DMA
transfer may wake up the udma routine, it's possible for this check to fail
and the udma routine will start unmapping pages when the transfer has only
just started. The result of this is unpredictable.

This fix simply delays the clearing of the IVTV_F_I_UDMA_PENDING flag until
after IVTV_F_I_UDMA has been set.

Abylay Ospan 0726681a70 V4L/DVB: 22-kHz set_tone fix for NetUP Dual DVB-S2-CI card. 22kHz logic controlled by demod
22-kHz tone can be driven in two ways:
1. LNBH24 can produce 22kHz continuous tone when TEN=1 ( 22 KHz tone output is
always activated ).
2. LNBH24 can reproduce 22kHz tone timings from DSQIN or EXTM pin's when TEN=0.
From LNBH24 datasheet:
"In order to improve design flexibility an external tone input pin is
available (EXTM). The EXTM is a Logic input pin which activates the 22 kHz
tone output, on the VoTX pin, by using the LNBH24 integrated tone generator
(similar to the DSQIN pin function). In fact, the output tone waveform
characteristics will always be internally controlled by the LNBH24 tone
generator and the EXTM signal will be used as a timing control for DiSEqC tone
data encoding on the VoTX output."

In NetUP Dual DVB-S2-CI card 22kHz tone timings on EXTM pin produced by
STV0900 demod:
.set_tone  = stv0900_set_tone

redefine to "set_tone = lnbp21_set_tone" is not correct for "NetUP Dual
DVB-S2-CI card".

The non gspca versions of these drivers not only show a lot of code
duplicty (amongsth each other), as they all copy the same generic usb
webcam code instead of using some sort of framework. They also have not
seen any updates for more then 2 years, where as the gspca drivers are

So it is time for the non gspca versions of these drivers to go away,

Michael Deegan <michael@ucc.gu.uwa.edu.au>, has reported issues with
using 640x480 mode on his ov518+ webcam. The fix for this breaks things
on my ov518+ cam (Trust 320 Sp@cecam), this patch thus adds differentiation
in the driver between the OV7620 sensor his cam has and the OV7620AE sensor
my cam has, and then only changes the init sequence for the ov518+ +
OV7620 combo which was not working for Michael.

If you read the mail to Oliver Neukum on the linux-usb list, then you know
that I found a cure for the mysterious problem that the MR97310a CIF "type
1" cameras have been freezing up and refusing to stream if hooked up to a
machine with a UHCI controller.

Namely, the cure is that if the camera is an mr97310a CIF type 1 camera, you
have to send it 0xa0, 0x00. Somehow, this is a timing reset command, or
such. It un-blocks whatever was previously stopping the CIF type 1 cameras
from working on the UHCI-based machines.

Abylay Ospan ceb59cf068 V4L/DVB (13936): 22-kHz set_tone fix for NetUP Dual DVB-S2-CI card
22-kHz tone can be driven in two ways:
1. LNBH24 can produce 22kHz continuous tone when TEN=1 ( 22 KHz tone output is
always activated ).
2. LNBH24 can reproduce 22kHz tone timings from DSQIN or EXTM pin's when TEN=0.
From LNBH24 datasheet:
"In order to improve design flexibility an external tone input pin is
available (EXTM). The EXTM is a Logic input pin which activates the 22 kHz
tone output, on the VoTX pin, by using the LNBH24 integrated tone generator
(similar to the DSQIN pin function). In fact, the output tone waveform
characteristics will always be internally controlled by the LNBH24 tone
generator and the EXTM signal will be used as a timing control for DiSEqC tone
data encoding on the VoTX output."

In NetUP Dual DVB-S2-CI card 22kHz tone timings on EXTM pin produced by
STV0900 demod:
.set_tone  = stv0900_set_tone

redefine to "set_tone = lnbp21_set_tone" is not correct for "NetUP Dual

Jiri Slaby e34d375aa6 V4L/DVB (13968): cx18, fix potential null dereference
Stanse found a potential null dereference in cx18_dvb_start_feed
and cx18_dvb_stop_feed. There is a check for stream being NULL,
but it is dereferenced earlier. Move the dereference after the
check.
