[PATCH CK 4.19 1/4] fuse: fix page dereference after free

by Peng Tao

From: Miklos Szeredi <mszeredi(a)redhat.com> commit d78092e4937de9ce55edcb4ee4c5e3c707be0190 upstream. fix #32833505 After unlock_request() pages from the ap->pages[] array may be put (e.g. by aborting the connection) and the pages can be freed. Prevent use after free by grabbing a reference to the page before calling unlock_request(). The original patch was created by Pradeep P V K.

[PATCH v5] drm: Use USB controller's DMA mask when importing dmabufs

by Thomas Zimmermann

USB devices cannot perform DMA and hence have no dma_mask set in their device structure. Therefore importing dmabuf into a USB-based driver fails, which breaks joining and mirroring of display in X11. For USB devices, pick the associated USB controller as attachment device. This allows the DRM import helpers to perform the DMA setup. If the DMA controller does not support DMA transfers, we're out of luck and cannot import. Our current USB-based DRM drivers don't use DMA, so the actual DMA device is not important. Drivers should use DRM_GEM_SHMEM_DROVER_OPS_USB to initialize their instance of struct drm_driver. Tested by joining/mirroring displays of udl and radeon un der Gnome/X11. v5: * provide a helper for USB interfaces (Alan) * add FIXME item to documentation and TODO list (Daniel) v4: * implement workaround with USB helper functions (Greg) * use struct usb_device->bus->sysdev as DMA device (Takashi) v3: * drop gem_create_object * use DMA mask of USB controller, if any (Daniel, Christian, Noralf) v2: * move fix to importer side (Christian, Daniel) * update SHMEM and CMA helpers for new PRIME callbacks Signed-off-by: Thomas Zimmermann <tzimmermann(a)suse.de> Fixes: 6eb0233ec2d0 ("usb: don't inherity DMA properties for USB devices") Tested-by: Pavel Machek <pavel(a)ucw.cz> Acked-by: Christian König <christian.koenig(a)amd.com> Acked-by: Daniel Vetter <daniel.vetter(a)ffwll.ch> Cc: Christoph Hellwig <hch(a)lst.de> Cc: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Cc: <stable(a)vger.kernel.org> # v5.10+ --- Documentation/gpu/todo.rst | 15 ++++++++++ drivers/gpu/drm/drm_prime.c | 45 ++++++++++++++++++++++++++++++ drivers/gpu/drm/tiny/gm12u320.c | 2 +- drivers/gpu/drm/udl/udl_drv.c | 2 +- drivers/usb/core/usb.c | 31 ++++++++++++++++++++ include/drm/drm_gem_shmem_helper.h | 16 +++++++++++ include/drm/drm_prime.h | 5 ++++ include/linux/usb.h | 24 ++++++++++++++++ 8 files changed, 138 insertions(+), 2 deletions(-) diff --git a/Documentation/gpu/todo.rst b/Documentation/gpu/todo.rst index f872d3d33218..c185e0a2951e 100644 --- a/Documentation/gpu/todo.rst +++ b/Documentation/gpu/todo.rst @@ -617,6 +617,21 @@ Contact: Daniel Vetter Level: Intermediate +Remove automatic page mapping from dma-buf importing +---------------------------------------------------- + +When importing dma-bufs, the dma-buf and PRIME frameworks automatically map +imported pages into the importer's DMA area.
