2007-08-30USB: fix DoS in pwc USB video driverOliver Neukum
the pwc driver has a disconnect method that waits for user space to close the device. This opens up an opportunity for a DoS attack, blocking the USB subsystem and making khubd's task busy wait in kernel space. This patch shifts freeing resources to close if an opened device is disconnected. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-08-09V4L: ivtv: Add locking to ensure stream setup is atomicHans Verkuil
Starting an MPEG and VBI capture simultaneously caused errors in the VBI setup: this setup was done twice when it should be done only for the first stream that is opened. Added a mutex to prevent this from happening.

2007-08-09V4L: ivtv: fix DMA timeout when capturing VBI + another streamHans Verkuil
The VBI DMA is handled in a special way and is marked with a bit. However, that bit was set at the wrong time and could be cleared by mistake if a PCM (or other) DMA request would arrive before the VBI DMA was completed. So on completion of the VBI DMA the driver no longer knew that that DMA transfer was for VBI data. And this in turn caused havoc with the card's DMA engine.

2007-08-09V4L: ivtv: fix broken VBI output supportHans Verkuil
The old service_set_out setting was still tested, even though it no longer was ever set and was in fact obsolete. This meant that everything that was written to /dev/vbi16 was ignored. Removed the service_set_out variable altogether and now it works again.

2007-07-03V4L/DVB (5818): CinergyT2: fix flush_workqueue() vs work->func() deadlockOleg Nesterov
Spotted and tested by Thomas Sattler <tsattler@gmx.de>. cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while holding cinergyt2->sem. This leads to deadlock because work->func() needs the same mutex to complete. Another bug is that this code in fact can't reliably stop the re-arming delayed_work. Convert this code to use cancel_rearming_delayed_work() and move it out of ->sem. Another mutex, ->wq_sem, was added to protect against the concurrent open/resume. This patch is a horrible hack to fix the lockup which happens in practice. As Dmitry Torokhov pointed out this driver has other problems and needs further changes.

2007-07-03V4L/DVB (5816): Cx88-blackbird: fix vidioc_g_tuner never ending list of tunersJelle Foks
v4l-info and other programs would loop indefinitely while querying the tuners for cx88-blackbird cards. The cause was that vidioc_g_tuner didn't return an error value for qctrl->id != 0, making the application think there is a never ending list of tuners...

2007-07-03V4L/DVB (5808): Bttv: fix v4l1 breaking the driverTrent Piepho
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as the first user after the driver is loaded, the driver wedges itself and will never capture properly. Even if one uses a V4L2 application later, it still won't work. If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2 driver, then the driver will be ok. One can then run a V4L1 application, and it will work. It turns out the problem is with norm changing and the crop support that was added in 2.6.21. The driver defaults to PAL, and keeps the last norm it was set too across opens. If one changes the norm via V4L1, the cropping parameters are not reset like they should be, and they'll remain broken across device opens. This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl VIDIOCSCHAN handler. The norm is set via the existing call to set_input(), which calls set_tvnorm(), which will reset the cropping values now that it is able to detect the norm change.

2007-06-28saa7134: fix thread shutdown handlingJeff Mahoney
This patch changes the test for the thread pid from >= 0 to > 0. When the saa8134 driver initialization fails after a certain point, it goes through the complete shutdown process for the driver. Part of shutting it down includes tearing down the thread for tv audio. The test for tearing down the thread tests for >= 0. Since the dev structure is kzalloc'd, the test will always be true if we haven't tried to start the thread yet. We end up waiting on pid 0 to complete, which will never happen, so we lock up. This bug was observed in Novell Bugzilla 284718, when request_irq() failed.

2007-06-28Fix Kconfig dependency problems wrt boolean menuconfigsTrent Piepho
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on (tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool promotes the tristate from m to y. This ends up causing a problem with several menuconfigs that look like: menuconfig BAR bool depends on BAZ [tristate] if BAR config FOO tristate endif The solution used here is to add the dependencies of BAR to the if statement, so that items in the if block will gain a direct non-bool-promoted dependency on BAZ. This is how it would work if a menu was used instead of an if block. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Mauro Carvalho Chehab <mchehab@infradead.org> Cc: "David S.

2007-06-08V4L/DVB (5700): Saa7111: fix picture settings cache bugRussell King
If the SAA7111 device is powered down, and requires re-initialisation when the V4L device is opened (as on the NetWinder), the SAA7111 driver gets completely confused about the current settings. The problem is centred around the way the driver keeps _two_ cached copies of the current settings - one of the struct video_picture settings, and one of the registers. When the decoder is re-initailised, the cached register settings are overwritten, as are the values in the hardware registers. However, the cached video_picture settings are not. Resolve this by removing the useless and buggy second level of caching for video_picture. Instead, provide a function which updates register values if and only if the value we are going to write to the register has changed.

Among other things, VIDIOCSPICT sets the pixel format. Some drivers don't support all formats, e.g. cx88 doesn't support the planar formats. The compat code that translates VIDIOCSPICT into V4L2 ioctls doesn't pass on any errors, so a userspace program doesn't know if it has selected an unsupported pixel format. VIDIOCSPICT sets both the memory capture and overlay formats, and it's possible that one will be set while the other will fail, e.g. cx88 doesn't even support overlay.

2007-05-09V4L/DVB (5607): M920x: Initial support for devices likely manufactured by DposhAapo Tahkola
These devices are sold by various companies and chains not involved in hardware manufacturing business. This particular device owned by winisch (from irc) had a sticker with text "TCM 234292" on it. This device was never opened so it is possible that Dposh did not manufacture this stick. However, the bundled software and their product line points into that direction. Also thanks to Michael Krufky for spotting this hw filtering problem and thus avoiding hair loss. Hardware pid filters and the bundled remote controller are not currently supported on this device.
