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.

10ee240200 V4L/DVB: gspca_main: some input error handling fixes
2 small changes to input device error handling:
1) Make it fatal when we fail to create an input device (it is either this
   or add checks for gspca_dev->input_dev being NULL in a lot of places)
2) Since we allow gspca_input_create_urb() to fail everywhere we call it,
   and thus never check its return value, make it void.

5fb2dde281 V4L/DVB: gspca_pac7302: much improved exposure control
My experience with fixing up the controls for the PAS sensors in
sonixb, has lead me to re-investigate the exposure control for the
pac7302. I've now found a regular exposure register in register bank 3
(which seems to be the sensor registers bank), and with this added a proper
fine grained exposure control. This patch also updates the do_autogain
function to work properly with this new finer grained control.

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.

7c12167bae V4L/DVB: ivtv: Add initial entry for Sony VAIO Giga Pocket (Kikyou) cards
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.

e54532e591 V4L/DVB: uvcvideo: Clamp control values to the minimum and maximum values
When setting a control, the V4L2 specification requires drivers to
either clamp the control value to the [minimum, maximum] range or return
the -ERANGE error.

Fix the driver to clamp control values to the valid range in
uvc_ctrl_set() and make sure the value differs from the minimum by an
integer multiple of step.

8a4e76c14c V4L/DVB: uvcvideo: Return -ERANGE when setting a control to an out-of-range menu index
The V4L2 specification states that out of bounds control values must
either be clamped to the valid range or result in a -ERANGE error code.

Fix the driver to return -ERANGE instead of -EINVAL when setting a menu
control to an invalid value.

56d15cd313 V4L/DVB: uvcvideo: Increase the streaming control timeout to 5 seconds
This fixes timeout issues with some Logitech webcams. The timeout value
seems to match the one used in the Logitech Windows driver, so no
further increase should be necessary.
