2010-02-26dvb-core: Fix DoS bug in ULE decapsulation code that can be triggered by an ↵Ang Way Chuang
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.

2010-02-26V4L/DVB: gspca_main: some input error handling fixesHans de Goede
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.

2010-02-26V4L/DVB: gspca_pac7302: much improved exposure controlHans de Goede
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.

2010-02-26V4L/DVB: gscpa_sonixb: Differentiate between sensors with a coarse and fine ↵Hans de Goede
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.

2010-02-26V4L/DVB: ivtv: Add initial entry for Sony VAIO Giga Pocket (Kikyou) cardsEric Anderson
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.

Now it only reads at most 7 of the 16 mailbox data words over the PCI bus, and in some instances only 2 or 3 data words as needed.

v4l2_device_register needs to be called before the i2c subdevs are loaded. However, it was called afterwards in the saa7146 driver. This caused an oops when loading the mxb and hexium drivers. The vv_init function is now split into two: one registers the v4l2_device, the other does the rest of the initialization.
