2021-06-02media: v4l2-core: Avoid the dangling pointer in v4l2_fh_releaseLv Yunlong1-0/+1
A use after free bug caused by the dangling pointer filp->privitate_data in v4l2_fh_release. See https://lore.kernel.org/patchwork/patch/1419058/. My patch sets the dangling pointer to NULL to provide robust.

2021-06-02media: exynos4-is: Fix a use after free in isp_video_releaseLv Yunlong1-2/+5
In isp_video_release, file->private_data is freed via _vb2_fop_release()->v4l2_fh_release(). But the freed file->private_data is still used in v4l2_fh_is_singular_file() ->v4l2_fh_is_singular(file->private_data), which is a use after free bug. My patch uses a variable 'is_singular_file' to avoid the uaf. v3: https://lore.kernel.org/patchwork/patch/1419058/ Fixes: 34947b8aebe3f ("[media] exynos4-is: Add the FIMC-IS ISP capture DMA driver") Signed-off-by: Lv Yunlong <lyl2019@mail.ustc.edu.cn> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'ace_allocate_descriptors()' and 'ace_init()' GFP_KERNEL can be used because both functions are called from the probe function and no lock is acquired. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-06-02media: adv7842: support EDIDs up to 4 blocksHans Verkuil1-10/+27
The adv7842 driver didn't support EDIDs of 3 or 4 blocks, even though the hardware supports this. It is a bit more complicated due to the fact that the adv7842 can expose two EDIDs: one digital, one analog, for DVI-I connectors. In that case the VGA_EDID_ENABLE bit is set and blocks 0 and 1 of the EDID eeprom are used for the DVI-D part and block 2 is used for the DVI-A part of the DVI-I connector.

2021-06-02media: venus: hfi_cmds.h: Replace one-element array with flexible-array memberGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Use flexible-array member in struct hfi_sys_set_property_pkt instead of one-element array. Also, this helps with the ongoing efforts to enable -Warray-bounds and fix the following warnings: drivers/media/platform/qcom/venus/hfi_cmds.c: In function ‘pkt_sys_coverage_config’: drivers/media/platform/qcom/venus/hfi_cmds.c:57:11: warning: array subscript 1 is above array bounds of ‘u32[1]’ {aka ‘unsigned int[1]’} [-Warray-bounds] 57 | pkt->data[1] = mode; | ~~~~~~~~~^~~ [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109 Build-tested-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/lkml/602416da.iZqae7Dbk7nyl6OY%25lkp@intel.com/ Signed-off-by: Gustavo A.

At the same time there is a vast number of systems that need videodev module, but have no use for v4l2-async that's now part of videodev. In order to improve, split the v4l2-async into its own module. Selecting V4L2_FWNODE also selects V4L2_ASYNC.

2021-06-02media: move ttpci-eeprom to commonMauro Carvalho Chehab7-7/+7
The ttpci-eeprom is actually an independent driver that doesn't depend on the stuff under drivers/media/pci/ttpci/. Also, it is used by an USB driver (pctv452e). So, move it to the common directory. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Pull xfs fixes from Darrick Wong: "This week's pile mitigates some decades-old problems in how extent size hints interact with realtime volumes, fixes some failures in online shrink, and fixes a problem where directory and symlink shrinking on extremely fragmented filesystems could fail. The most user-notable change here is to point users at our (new) IRC channel on OFTC. Freedom isn't free, it costs folks like you and me; and if you don't kowtow, they'll expel everyone and take over your channel. (Ok, ok, that didn't fit the song lyrics...) Summary: - Fix a bug where unmapping operations end earlier than expected, which can cause chaos on multi-block directory and symlink shrink operations. - Fix an erroneous assert that can trigger if we try to transition a bmap structure from btree format to extents format with zero extents. This was exposed by xfs/538" * tag 'xfs-5.13-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: bunmapi has unnecessary AG lock ordering issues xfs: btree format inode forks can have zero extents xfs: add new IRC channel to MAINTAINERS xfs: validate extsz hints against rt extent size when rtinherit is set xfs: standardize extent size hint validation xfs: check free AG space when making per-AG reservations
2021-05-29seccomp: Refactor notification handler to prepare for new semanticsSargun Dhillon1-14/+16
This refactors the user notification code to have a do / while loop around the completion condition. This has a small change in semantic, in that previously we ignored addfd calls upon wakeup if the notification had been responded to, but instead with the new change we check for an outstanding addfd calls prior to returning to userspace. Rodrigo Campos also identified a bug that can result in addfd causing an early return, when the supervisor didn't actually handle the syscall [1].
