[ Upstream commit 9f5039ba440e499d85c29b1ddbc3cbc9dc90e44b ] Since commit e8f4818895b3 ("[media] lirc: advertise LIRC_CAN_GET_REC_RESOLUTION and improve") lircd uses the ioctl LIRC_GET_REC_RESOLUTION to determine the shortest pulse or space that the hardware can detect. This breaks decoding in lirc because lircd expects the answer in microseconds, but nanoseconds is returned.

2017-09-10media: platform: davinci: return -EINVAL for VPFE_CMD_S_CCDC_RAW_PARAMS ioctlPrabhakar Lad
[ Upstream commit da05d52d2f0f6bd61094a0cd045fed94bf7d673a ] this patch makes sure VPFE_CMD_S_CCDC_RAW_PARAMS ioctl no longer works for vpfe_capture driver with a minimal patch suitable for backporting. - This ioctl was never in public api and was only defined in kernel header. - The function set_params constantly mixes up pointers and phys_addr_t numbers. - This is part of a 'VPFE_CMD_S_CCDC_RAW_PARAMS' ioctl command that is described as an 'experimental ioctl that will change in future kernels'. - The code to allocate the table never gets called after we copy_from_user the user input over the kernel settings, and then compare them for inequality. - We then go on to use an address provided by user space as both the __user pointer for input and pass it through phys_to_virt to come up with a kernel pointer to copy the data to. This looks like a trivially exploitable root hole. Due to these reasons we make sure this ioctl now returns -EINVAL and backport this patch as far as possible.

2017-09-10[media] cx88: Fix regression in initial video standard settingDevin Heitmueller
[ Upstream commit 4e0973a918b9a42e217093f078e04a61e5dd95a5 ] Setting initial standard at the top of cx8800_initdev would cause the first call to cx88_set_tvnorm() to return without programming any registers (leaving the driver saying it's set to NTSC but the hardware isn't programmed). Even worse, any subsequent attempt to explicitly set it to NTSC-M will return success but actually fail to program the underlying registers unless first changing the standard to something other than NTSC-M. Set the initial standard later in the process, and make sure the field is zero at the beginning to ensure that the call always goes through. This regression was introduced in the following commit: commit ccd6f1d488e7 ("[media] cx88: move width, height and field to core struct") Author: Hans Verkuil <hans.verkuil@cisco.com> [media] cx88: move width, height and field to core struct Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Cc: <stable@vger.kernel.org> # for v3.19 and up Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Sasha Levin <alexander.levin@verizon.com>

2017-06-25[media] pvrusb2: reduce stack usage pvr2_eeprom_analyze()Arnd Bergmann
[ Upstream commit 6830733d53a4517588e56227b9c8538633f0c496 ] The driver uses a relatively large data structure on the stack, which showed up on my radar as we get a warning with the "latent entropy" GCC plugin: drivers/media/usb/pvrusb2/pvrusb2-eeprom.c:153:1: error: the frame size of 1376 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] The warning is usually hidden as we raise the warning limit to 2048 when the plugin is enabled, but I'd like to lower that again in the future, and making this function smaller helps to do that without build regressions. Further analysis shows that putting an 'i2c_client' structure on the stack is not really supported, as the embedded 'struct device' is not initialized here, and we are only saved by the fact that the function that is called here does not use the pointer at all.

2017-06-13xc2028: Fix use-after-free bug properlyTakashi Iwai
[ Upstream commit 22a1e7783e173ab3d86018eb590107d68df46c11 ] The commit 8dfbcc4351a0 ("[media] xc2028: avoid use after free") tried to address the reported use-after-free by clearing the reference. However, it's clearing the wrong pointer; it sets NULL to priv->ctrl.fname, but it's anyway overwritten by the next line memcpy(&priv->ctrl, p, sizeof(priv->ctrl)). OTOH, the actual code accessing the freed string is the strcmp() call with priv->fname: if (!firmware_name[0] && p->fname && priv->fname && strcmp(p->fname, priv->fname)) free_firmware(priv); where priv->fname points to the previous file name, and this was already freed by kfree(). For fixing the bug properly, this patch does the following: - Keep the copy of firmware file name in only priv->fname, priv->ctrl.fname isn't changed; - The allocation is done only when the firmware gets loaded; - The kfree() is called in free_firmware() commonly Fixes: commit 8dfbcc4351a0 ('[media] xc2028: avoid use after free') Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Sasha Levin <alexander.levin@verizon.com>

2017-06-13[media] dvb-usb-v2: avoid use-after-freeArnd Bergmann
[ Upstream commit 005145378c9ad7575a01b6ce1ba118fb427f583a ] I ran into a stack frame size warning because of the on-stack copy of the USB device structure: drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_disconnect': drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:1029:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Copying a device structure like this is wrong for a number of other reasons too aside from the possible stack overflow. One of them is that the dev_info() call will print the name of the device later, but AFAICT we have only copied a pointer to the name earlier and the actual name has been freed by the time it gets printed. This removes the on-stack copy of the device and instead copies the device name using kstrdup(). I'm ignoring the possible failure here as both printk() and kfree() are able to deal with NULL pointers.

2017-05-17[media] am437x-vpfe: always assign bpp variableNicolas Iooss
[ Upstream commit 6ebf75774f823ddbdbd10921006989d4df222f4a ] In vpfe_s_fmt(), when the sensor format and the requested format were the same, bpp was assigned to vpfe->bpp without being initialized first. Grab the bpp value that is currently used by using __vpfe_get_format() instead of its wrapper, vpfe_try_fmt(). This use of uninitialized variable has been found by compiling the kernel with clang.

2017-03-06[media] siano: make it work again with CONFIG_VMAP_STACKMauro Carvalho Chehab
[ Upstream commit f9c85ee67164b37f9296eab3b754e543e4e96a1c ] Reported as a Kaffeine bug: https://bugs.kde.org/show_bug.cgi?id=375811 The USB control messages require DMA to work. We cannot pass a stack-allocated buffer, as it is not warranted that the stack would be into a DMA enabled area. On Kernel 4.9, the default is to not accept DMA on stack anymore on x86 architecture. On other architectures, this has been a requirement since Kernel 2.2. So, after this patch, this driver should likely work fine on all archs.

2017-01-10mxc_v4l2_capture: Change error message to print on debugSanchayan Maity
Change the "unsupported ioctrl" message to print only on debug. This otherwise results in an error message ERROR: v4l2 capture: unsupported ioctrl! which does not seem to effect the gstreamer pipeline or rendering of video. >From debugging, root@apalis-imx6:~# gst-launch-1.0 imxv4l2videosrc ! imxeglvivsink Setting pipeline to PAUSED ...

"The V4L2_CID_3A_LOCK bitmask control allows applications to pause or resume the automatic exposure, focus and wite balance adjustments. It can be used, for example, to lock the 3A adjustments right before a still image is captured, for pre-focus, etc. The applications can control each of the algorithms independently, through a corresponding control bit, if driver allows that." https://patchwork.linuxtv.org/patch/10719/ Since we have no such feature available we can safely disable the error message.

2017-01-10mxc_v4l2_capture: Allow clock setting for de-interlaced video inputSanchayan Maity
Make provision for a decoder driver to specify clock mode for progressive in case the decoder provides deinterlaced output. This is required for ADV7280 decoder where we can use the hardware deinterlace capabity of ADV7280. Without setting the clock mode to progressive but having hardware deinterlace on for ADV7280 results in a non working setup.
