[ Upstream commit9f0bcf49e9] This is motivated by OOB access in amdgpu_vm_update_range when offset_in_bo+map_size overflows. v2: keep the validations in amdgpu_vm_bo_map v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map rather than to amdgpu_gem_va_ioctl Fixes:9f7eb5367d("drm/amdgpu: actually use the VM map parameters") Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Chia-I Wu <olvaffe@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
