Commit 63a613fdb16c ("memory: tegra: Add gr2d and gr3d to DRM IOMMU
|
||||
group") added the GPU to the DRM IOMMU group, which doesn't make any
|
||||
sense. This causes problems when Nouveau tries to attach to the SMMU
|
||||
and causes it to fall back to using the DMA API.
|
||||
|
||||
Remove the GPU from the DRM groups to restore the old behaviour. The
|
||||
GPU should always have its own IOMMU domain to make sure it can map
|
||||
buffers into contiguous chunks (for big page support) without getting
|
||||
in the way of mappings from the DRM group.
|
||||

||||

Subject: net/packet: fix overflow in tpacket_rcv
|
||||
|
||||
From: Or Cohen <orcohen@paloaltonetworks.com>
|
||||
|
||||
[ Upstream commit acf69c946233259ab4d64f8869d4037a198c7f06 ]
|
||||
|
||||
Using tp_reserve to calculate netoff can overflow as
|
||||
tp_reserve is unsigned int and netoff is unsigned short.
|
||||
|
||||
This may lead to macoff receving a smaller value then
|
||||
sizeof(struct virtio_net_hdr), and if po->has_vnet_hdr
|
||||
is set, an out-of-bounds write will occur when
|
||||
calling virtio_net_hdr_from_skb.
|
||||
|
||||
The bug is fixed by converting netoff to unsigned int
|
||||
and checking if it exceeds USHRT_MAX.
|
||||
|
||||
This addresses CVE-2020-14386
