2022-10-25media: vivid: set num_in/outputs to 0 if not supportedHans Verkuil1-4/+12

2022-10-25media: vivid: fix control handler mutex deadlockHans Verkuil1-0/+8
vivid_update_format_cap() can be called from an s_ctrl callback. In that case (keep_controls == true) no control framework functions can be called that take the control handler mutex. The new call to v4l2_ctrl_modify_dimensions() did exactly that.

Add sanity checks to v4l2_valid_dv_timings() to ensure that the provided blanking values are reasonable. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Fixes: b18787ed1ce3 ([media] v4l2-dv-timings: add new helper module) Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2022-10-25media: vivid: dev->bitmap_cap wasn't freed in all casesHans Verkuil1-5/+13
Whenever the compose width/height values change, the dev->bitmap_cap vmalloc'ed array must be freed and dev->bitmap_cap set to NULL. This was done in some places, but not all. This is only an issue if overlay support is enabled and the bitmap clipping is used.

VIDIOC_S_FBUF is by definition a scary ioctl, which is why only root can use it. But at least check if the framebuffer parameters match that of one of the framebuffer created by vivid, and reject anything else.

Pull missed media updates from Mauro Carvalho Chehab: "It seems I screwed-up my previous pull request: it ends up that only half of the media patches that were in linux-next got merged in -rc1. The script which creates the signed tags silently failed due to 5.19->6.0 so it ended generating a tag with incomplete stuff. So here are the missing parts: - a DVB core security fix - lots of fixes and cleanups for atomisp staging driver - old drivers that are VB1 are being moved to staging to be deprecated - several driver updates - mostly for embedded systems, but there are also some things addressing issues with some PC webcams, in the UVC video driver" * tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (163 commits) media: sun6i-csi: Move csi buffer definition to main header file media: sun6i-csi: Introduce and use video helper functions media: sun6i-csi: Add media ops with link notify callback media: sun6i-csi: Remove controls handler from the driver media: sun6i-csi: Register the media device after creation media: sun6i-csi: Pass and store csi device directly in video code media: sun6i-csi: Tidy up video code media: sun6i-csi: Tidy up v4l2 code media: sun6i-csi: Tidy up Kconfig media: sun6i-csi: Use runtime pm for clocks and reset media: sun6i-csi: Define and use variant to get module clock rate media: sun6i-csi: Always set exclusive module clock rate media: sun6i-csi: Tidy up platform code media: sun6i-csi: Refactor main driver data structures media: sun6i-csi: Define and use driver name and (reworked) description media: cedrus: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-rotate: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-di: Add a Kconfig dependency on RESET_CONTROLLER media: sun4i-csi: Add a Kconfig dependency on RESET_CONTROLLER media: sun6i-csi: Add a Kconfig dependency on RESET_CONTROLLER ...
2022-10-11treewide: use get_random_u32() when possibleJason A. Donenfeld1-2/+2
The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

2022-09-27media: mediatek: vcodec: Drop platform_get_resource(IORESOURCE_IRQ)Nícolas F. R. A. Prado1-6/+3
Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") removed support for calling platform_get_resource(..., IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of mtk-vcodec's encoder was still making use of it. This caused the encoder driver to fail probe. Since the platform_get_resource() call was only being used to check for the presence of the interrupt (its returned resource wasn't even used) and platform_get_irq() was already being used to get the IRQ, simply drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the failure of platform_get_irq(), to get the driver probing again.

2022-09-27media: v4l2-ioctl.c: fix incorrect error pathHans Verkuil1-14/+12
If allocating array_buf fails, or copying data from userspace into that buffer fails, then just free memory and return the error. Don't attempt to call video_put_user() since there is no point, and it would copy back data on error even if INFO_FL_ALWAYS_COPY wasn't set. So if writing the array back to userspace fails, then don't go to out_array_args, instead just continue with the regular code that just returns the error unless 'always_copy' is set. Update the VIDIOC_G/S/TRY_EXT_CTRLS ioctls to set the ALWAYS_COPY flag since they now need it. Before this worked due to this buggy code, but now that that is fixed these ioctls need to set this flag explicitly.
