2018-09-20drm/i915/selftests: Live tests emit requests and so require rpmChris Wilson
As we emit requests or touch HW directly for some of the live tests, the requirement is that we hold the rpm wakeref before doing so. We want a mix of granularity since we will want to test runtime suspend, so try to mark up only the critical sections where we need rpm for the live test.

For some reason I thought GPIOLIB handles translation from GPIO ranges to pinctrl pins but it turns out not to be the case. This means that when GPIOs operations are performed for a pin controller having a custom GPIO base such as Cannon Lake and Ice Lake incorrect pin number gets used internally.

2018-09-20floppy: Do not copy a kernel pointer to user memory in FDGETPRM ioctlAndy Whitcroft
The final field of a floppy_struct is the field "name", which is a pointer to a string in kernel memory. The kernel pointer should not be copied to user memory. The FDGETPRM ioctl copies a floppy_struct to user memory, including this "name" field. This pointer cannot be used by the user and it will leak a kernel address to user-space, which will reveal the location of kernel code and data and undermine KASLR protection. Model this code after the compat ioctl which copies the returned data to a previously cleared temporary structure on the stack (excluding the name pointer) and copy out to userspace from there. As we already have an inparam union with an appropriate member and that memory is already cleared even for read only calls make use of that as a temporary store.

2018-09-20drm/i915/guc: Restore preempt-context across S3/S4Chris Wilson
Stolen memory is lost across S4 (hibernate) or S3-RST as it is a portion of ordinary volatile RAM. As we allocate our rings from stolen, this may include the rings used for our preempt context and their breadcrumb instructions. In order to allow preemption following hibernation and loss of stolen memory, we therefore need to repopulate the instructions inside the lost ring upon resume.

2018-09-20USB: handle NULL config in usb_find_alt_setting()Alan Stern
usb_find_alt_setting() takes a pointer to a struct usb_host_config as an argument; it searches for an interface with specified interface and alternate setting numbers in that config. However, it crashes if the usb_host_config pointer argument is NULL. Since this is a general-purpose routine, available for use in many places, we want to to be more robust. This patch makes it return NULL whenever the config argument is NULL.

2018-09-20USB: fix error handling in usb_driver_claim_interface()Alan Stern
The syzbot fuzzing project found a use-after-free bug in the USB core. The bug was caused by usbfs not unbinding from an interface when the USB device file was closed, which led another process to attempt the unbind later on, after the private data structure had been deallocated. The reason usbfs did not unbind the interface at the appropriate time was because it thought the interface had never been claimed in the first place. This was caused by the fact that usb_driver_claim_interface() does not clean up properly when device_bind_driver() returns an error. Although the error code gets passed back to the caller, the iface->dev.driver pointer remains set and iface->condition remains equal to USB_INTERFACE_BOUND. This patch adds proper error handling to usb_driver_claim_interface().

2018-09-20USB: remove LPM management from usb_driver_claim_interface()Alan Stern
usb_driver_claim_interface() disables and re-enables Link Power Management, but it shouldn't do either one, for the reasons listed below. This patch removes the two LPM-related function calls from the routine. The reason for disabling LPM in the analogous function usb_probe_interface() is so that drivers won't have to deal with unwanted LPM transitions in their probe routine. But usb_driver_claim_interface() doesn't call the driver's probe routine (or any other callbacks), so that reason doesn't apply here. Furthermore, no driver other than usbfs will ever call usb_driver_claim_interface() unless it is already bound to another interface in the same device, which means disabling LPM here would be redundant. usbfs doesn't interact with LPM at all. Lastly, the error return from usb_unlocked_disable_lpm() isn't handled properly; the code doesn't clean up its earlier actions before returning.

2018-09-20drm/vmwgfx: Fix buffer object evictionThomas Hellstrom
Commit 19be55701071 ("drm/ttm: add operation ctx to ttm_bo_validate v2") introduced a regression where the vmwgfx driver refused to evict a buffer that was still busy instead of waiting for it to become idle. Fix this. Cc: <stable@vger.kernel.org> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Christian König <christian.koenig@amd.com>

2018-09-20drm/vmwgfx: limit screen size to stdu_max during check_modesetDeepak Rawat
For STDU individual screen target size is limited by SVGA_REG_SCREENTARGET_MAX_WIDTH/HEIGHT registers so add that limit during atomic check_modeset. An additional limit is placed in the update_layout ioctl to avoid requesting layouts that current user-space typically can't support. Also modified the comments to reflect current limitation on topology.

2018-09-20drm/vmwgfx: don't check for old_crtc_state enable statusDeepak Rawat
During atomic check to prepare the new topology no need to check if old_crtc_state was enabled or not. This will cause atomic_check to fail because due to connector routing a crtc can be in atomic_state even if there was no change to enable status. Detected this issue with igt run.

2018-09-19net: mvneta: fix the Rx desc buffer DMA unmappingAntoine Tenart
With CONFIG_DMA_API_DEBUG enabled we now get a warning when using the mvneta driver: mvneta d0030000.ethernet: DMA-API: device driver frees DMA memory with wrong function [device address=0x000000001165b000] [size=4096 bytes] [mapped as page] [unmapped as single] This is because when using the s/w buffer management, the Rx descriptor buffer is mapped with dma_map_page but unmapped with dma_unmap_single. This patch fixes this by using the right unmapping function.
