invalid Payload Pointer
commit 29e1fa3565a7951cc415c634eb2b78dbdbee151d upstream.
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.

cxusb uses the atbm8830 and lgs8gxx (not lgs8gl5) frontends and the
max2165 tuner, so it needs to select them.

commit c1db53b36633e6a7511dbec7c372f01a31528f0c upstream.
I'm trying to fix it on the GCC side (PR43007), but the module is
quite stupid in using ULL constants to operate on u32 values:
static int apply_frontend_param (struct dvb_frontend* fe, struct
dvb_frontend_parameters *param)
{
...
static const u32 ppm = 8000;
u32 spi_bias;
...
spi_bias *= 1000ULL;
spi_bias /= 1000ULL + ppm/1000;
which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again.
This patch fixes this issue.

commit 691c9ae099b9bcb5c27125af00a4a90120977458 upstream.
A DVB demultiplexer device can be used to set up either a PES filter or
a section filter. In the former case, the ts field of the feed union of
struct dmxdev_filter is used, in the latter case the sec field of the
same union is used.
The ts field is a struct list_head, and is currently initialized in the
open() method of the demux device. When for a given demuxer a section
filter is set up, the sec field is played with, thus if a PES filter
needs to be set up after that the ts field will be corrupted, causing a
kernel oops.
This fix moves the list head initialization to
dvb_dmxdev_pes_filter_set(), so that the ts field is properly
initialized every time a PES filter is set up.

This solves a problem in firedtv that has become major for Swedish DVB-T
users the last month or so. It will most likely solve issues seen by
other users as well.
If the length of an AVC message is greater than 127, the length field
should be encoded in LV mode instead of V mode. V mode can only be used
if the length is 127 or less. This patch ensures that the CA_PMT
message is always encoded in LV mode so PMT message of greater lengths
can be supported.

Fixing kernel oops when driver attemps to load xc2028 firmware.
Note by djh: the patch contribute by Martin is a port of a fix I made during
the PCTV 340e development. It's a temporary workaround that fixes a regression
(an OOPS condition) and the real fix should be in the code that manages the
i2c master on the dib7000p. But this fix does address the immmediate
regression and should be merged upstream until we do a cleaner fix.

Here's another new build breakage that triggers in -tip testing:
drivers/built-in.o:(.data+0xb1f40): undefined reference to `dib0070_ctrl_agc_filter'
drivers/built-in.o:(.data+0xb1f80): undefined reference to `dib0070_ctrl_agc_filter'
triggers due to:
CONFIG_DVB_USB_DIB0700=y
CONFIG_DVB_TUNER_DIB0070 is not set
While working on a better approach, for now, let's just select tuner
dib0070 anytime we compile dib0700.

As pointed by Marcin Slusarz <marcin.slusarz@gmail.com>, the warns happens
because CONFIG_DVB_MAX_ADAPTERS depends on CONFIG_DVB_CORE, and there are
valid configs where DVB_CORE is not selected.
This causes such warnings, for every V4L and common drivers that may or
may not be compiled with DVB support:
drivers/media/dvb/dvb-core/dvbdev.h:36:2: warning: #warning invalid CONFIG_DVB_MAX_ADAPTERS value
We can safely remove the warning.

This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.
This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

This patch adds driver for 774 Friio White, ISDB-T USB receiver
Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/)
The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module.
This driver ignores all the frontend_parameters except frequency,
as ISDB-T shares the same parameter configuration across the country
and thus the device can work like an intelligent one.
As this device does not include a CAM nor hardware descrambling feature,
the driver passes through scrambled TS streams.
There is Friio Black, a variant for ISDB-S, which shares the same USB
Vendor/Product ID with White, but it is not supported in this driver.
They should be identified in the initialization sequence,
but this feature is not tested.

Add a driver for Earthsoft PT1
Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S
and ISDB-T demodulators.
This card has neither MPEG decoder nor conditional access module
onboard. It transmits only compressed and possibly encrypted MPEG data
over the PCI bus, so you need an external software decoder and a
decrypter to watch TV on your computer.
This driver is originally developed by Tomoaki Ishikawa
<tomy@users.sourceforge.jp> by reverse engineering.

In ISDB-S, time-devision duplex is used to multiplexing several waves
in the same frequency. Each wave is identified by its own transport
stream ID, or TS ID. We need to provide some way to specify this ID
from user applications to handle ISDB-S frontends.
This code has been tested with the Earthsoft PT1 driver.
