usb: core: kcov: collect coverage from usb complete callback

2020-06-05T02:06:20Z

This patch adds kcov_remote_start/stop() callbacks around the urb complete() callback that is executed in softirq context when dummy_hcd is in use. As the result, kcov can be used to collect coverage from those callbacks, which is used to facilitate coverage-guided fuzzing with syzkaller.

usb: hci: add hc_driver as argument for usb_hcd_pci_probe

2020-05-15T13:44:34Z

usb_hcd_pci_probe expects users to call this with driver_data set as hc_driver, that limits the possibility of using the driver_data for driver data. Add hc_driver as argument to usb_hcd_pci_probe and modify the callers ehci/ohci/xhci/uhci to pass hc_driver as argument and freeup the driver_data used Tested xhci driver on Dragon-board RB3, compile tested ehci, ohci and uhci.

usb: core: hub: limit HUB_QUIRK_DISABLE_AUTOSUSPEND to USB5534B

The problem described in v5.6 commit 1208f9e1d758c9 ("USB: hub: Fix the broken detection of USB3 device in SMSC hub") applies solely to the USB5534B hub [2] present on the Kingfisher Infotainment Carrier Board, manufactured by Shimafuji Electric Inc [3]. Despite that, the aforementioned commit applied the quirk to _all_ hubs carrying vendor ID 0x424 (i.e. SMSC), of which there are more [4] than initially expected. Consequently, the quirk is now enabled on platforms carrying SMSC/Microchip hub models which potentially don't exhibit the original issue. To avoid reports like [1], further limit the quirk's scope to USB5534B [2], by employing both Vendor and Product ID checks. Tested on H3ULCB + Kingfisher rev. M05.

USB: usbfs: fix mmap dma mismatch

2020-05-14T16:39:57Z

In commit 2bef9aed6f0e ("usb: usbfs: correct kernel->user page attribute mismatch") we switched from always calling remap_pfn_range() to call dma_mmap_coherent() to handle issues with systems with non-coherent USB host controller drivers. Unfortunatly, as syzbot quickly told us, not all the world is host controllers with DMA support, so we need to check what host controller we are attempting to talk to before doing this type of allocation. Thanks to Christoph for the quick idea of how to fix this.
