variable *nplanes is provided by user via system call argument. The possible value of q_data->fmt->num_planes is 1-3, while the value of *nplanes can be 1-8. The array access by index i can cause array out-of-bounds. Fix this bug by checking *nplanes against the array size.

v4l_bound_align_image() aligns to a multiple of 2 to the power of walign, not to walign. Depending on the pixel format, this causes the image width to be aligned to 16 or 256 pixels instead of 4 or 8 as required by the hardware. Fix it by rounding and clamping the width and height manually.

2023-07-28media: uvcvideo: Fix menu count handling for userspace XU mappingsLaurent Pinchart1-1/+1
When commit 716c330433e3 ("media: uvcvideo: Use standard names for menus") reworked the handling of menu controls, it inadvertently replaced a GENMASK(n - 1, 0) with a BIT_MASK(n). The latter isn't equivalent to the former, which broke adding XU mappings from userspace. Fix it.

2023-07-28media: mtk-jpeg: Set platform driver data earlierChen-Yu Tsai1-2/+2
In the multi-core JPEG encoder/decoder setup, the driver for the individual cores references the parent device's platform driver data. However, in the parent driver, this is only set at the end of the probe function, way later than devm_of_platform_populate(), which triggers the probe of the cores. This causes a kernel splat in the sub-device probe function. Move platform_set_drvdata() to before devm_of_platform_populate() to fix this.

2023-07-14media: verisilicon: change confusingly named relaxed register accessArnd Bergmann2-11/+11
The register abstraction has wrappers around both the normal writel() and its writel_relaxed() counterpart, but this has led to a lot of users ending up with the relaxed version. There is sometimes a need to intentionally pick the relaxed accessor for performance critical functions, but I noticed that each hantro_reg_write() call also contains a non-relaxed readl(), which is typically much more expensive than a writel, so there is little benefit here but an added risk of missing a serialization against DMA. To make this behave like other interfaces, use the normal accessor by default and only provide the relaxed version as an alternative for performance critical code. hantro_postproc.c is the only place that used both the relaxed and normal writel, but this does not seem cricital either, so change it all to the normal ones.

2023-07-14media: verisilicon: fix excessive stack usageArnd Bergmann1-21/+21
In some configurations, gcc decides not to inline the register accessor functions, which in turn leads to lots of temporary hantro_reg structures on the stack that cannot be eliminated because they escape into an uninlined function: drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:1022:1: warning: the frame size of 1112 bytes is larger than 1024 bytes [-Wframe-larger-than=] Mark all of these as __always_inline so the compiler is able to completely eliminate the temporary structures instead, which brings the stack usage back down to just the normal local variables.

The mtk8195_jpegenc_drvdata object was added outside of an #ifdef causing a harmless build warning. drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable] 1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = { | ^~~~~~~~~~~~~~~~~~~~~~~ A follow-up patch moved it inside of an #ifdef, which caused more warnings, and a third patch ended up adding even more #ifdefs. These were all bogus, since the actual problem here is the incorrect use of of_ptr(). Since the driver (like any other modern platform driver) only works in combination with CONFIG_OF, there is no point in hiding the reference, so just remove that along with all the pointless #ifdef checks in the driver. This improves build coverage and avoids running into the same problem again when another part of the driver gets changed that relies on the #ifdef blocks to be completely matched.

Clang-16 produces this warning, which is fatal with CONFIG_WERROR: ../drivers/media/radio/wl128x/fmdrv_common.c:1237:19: error: variable 'cmd_cnt' set but not used [-Werror,-Wunused-but-set-variable] int ret, fw_len, cmd_cnt; ^ 1 error generated. What happens is that cmd_cnt tracks the amount of firmware data packets were transfered, which is printed only when debug is used. Switch to use the firmware count, as the message is all about reporting a partial firmware transfer.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior" * tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues net: qrtr: Use alloc_ordered_workqueue() to create ordered workqueues net: wwan: t7xx: Use alloc_ordered_workqueue() to create ordered workqueues dm integrity: Use alloc_ordered_workqueue() to create ordered workqueues media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues scsi: NCR5380: Use default @max_active for hostdata->work_q media: coda: Use alloc_ordered_workqueue() to create ordered workqueues crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueues wifi: mwifiex: Use default @max_active for workqueues wifi: iwlwifi: Use default @max_active for trans_pcie->rba.alloc_wq xen/pvcalls: Use alloc_ordered_workqueue() to create ordered workqueues virt: acrn: Use alloc_ordered_workqueue() to create ordered workqueues net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues net: thunderx: Use alloc_ordered_workqueue() to create ordered workqueues greybus: Use alloc_ordered_workqueue() to create ordered workqueues powerpc, workqueue: Use alloc_ordered_workqueue() to create ordered workqueues

2023-06-09media: verisilicon: Conditionally ignore native formatsBenjamin Gaignard5-25/+63
AV1 film grain feature requires to use the postprocessor to produce valid frames. In such case the driver shouldn't propose native pixels format but only post-processed pixels format. Additionally if when setting a control a value could change capture queue pixels formats it is needed to call hantro_reset_raw_fmt().
