[PATCH next] dma-buf/sync-file: do not allow zero size allocations

by Pavel Skripkin

syzbot reported GPF in dma_fence_array_first(), which is caused by dereferencing ZERO_PTR in dma-buf internals. ZERO_PTR was generated in sync_file_merge(). This functuion tries to reduce allocation size, but does not check if it reducing to 0. Fix reported bug by validating `index` value before passing it to krealloc_array(). Fail log: general protection fault, probably for non-canonical address 0xdffffc0000000002: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017] CPU: 1 PID: 3595 Comm: syz-executor814 Not tainted 5.17.0-next-20220328-syzkaller #0 ...

[PATCH AUTOSEL 4.19 03/29] drm/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj

by Sasha Levin

From: Xin Xiong <xiongx18(a)fudan.edu.cn> [ Upstream commit dfced44f122c500004a48ecc8db516bb6a295a1b ] This issue takes place in an error path in amdgpu_cs_fence_to_handle_ioctl(). When `info->in.what` falls into default case, the function simply returns -EINVAL, forgetting to decrement the reference count of a dma_fence obj, which is bumped earlier by amdgpu_cs_get_fence(). This may result in reference count leaks. Fix it by decreasing the refcount of specific object before returning the error code.

[PATCH v2 00/12] iio: buffer-dma: write() and new DMABUF based API

by Paul Cercueil

Hi Jonathan, This is the V2 of my patchset that introduces a new userspace interface based on DMABUF objects to complement the fileio API, and adds write() support to the existing fileio API. Changes since v1: - the patches that were merged in v1 have been (obviously) dropped from this patchset; - the patch that was setting the write-combine cache setting has been dropped as well, as it was simply not useful. - [01/12]: * Only remove the outgoing queue, and keep the incoming queue, as we want the buffer to start streaming data as soon as it is enabled. * Remove IIO_BLOCK_STATE_DEQUEUED, since it is now functionally the same as IIO_BLOCK_STATE_DONE. - [02/12]: * Fix block->state not being reset in iio_dma_buffer_request_update() for output buffers. * Only update block->bytes_used once and add a comment about why we update it. * Add a comment about why we're setting a different state for output buffers in iio_dma_buffer_request_update() * Remove useless cast to bool (!!) in iio_dma_buffer_io() - [05/12]: Only allow the new IOCTLs on the buffer FD created with IIO_BUFFER_GET_FD_IOCTL(). - [12/12]: * Explicitly state that the new interface is optional and is not implemented by all drivers. * The IOCTLs can now only be called on the buffer FD returned by IIO_BUFFER_GET_FD_IOCTL. * Move the page up a bit in the index since it is core stuff and not driver-specific. The patches not listed here have not been modified since v1. Cheers, -Paul Alexandru Ardelean (1): iio: buffer-dma: split iio_dma_buffer_fileio_free() function Paul Cercueil (11): iio: buffer-dma: Get rid of outgoing queue iio: buffer-dma: Enable buffer write support iio: buffer-dmaengine: Support specifying buffer direction iio: buffer-dmaengine: Enable write support iio: core: Add new DMABUF interface infrastructure iio: buffer-dma: Use DMABUFs instead of custom solution iio: buffer-dma: Implement new DMABUF based userspace API iio: buffer-dmaengine: Support new DMABUF based userspace API iio: core: Add support for cyclic buffers iio: buffer-dmaengine: Add support for cyclic buffers Documentation: iio: Document high-speed DMABUF based API Documentation/driver-api/dma-buf.rst | 2 + Documentation/iio/dmabuf_api.rst | 94 +++ Documentation/iio/index.rst | 2 + drivers/iio/adc/adi-axi-adc.c | 3 +- drivers/iio/buffer/industrialio-buffer-dma.c | 610 ++++++++++++++---- .../buffer/industrialio-buffer-dmaengine.c | 42 +- drivers/iio/industrialio-buffer.c | 60 ++ include/linux/iio/buffer-dma.h | 38 +- include/linux/iio/buffer-dmaengine.h | 5 +- include/linux/iio/buffer_impl.h | 8 + include/uapi/linux/iio/buffer.h | 30 + 11 files changed, 749 insertions(+), 145 deletions(-) create mode 100644 Documentation/iio/dmabuf_api.rst -- 2.34.1
