From c61769bd4777a922952aed0d042a2572e5bd9b74 Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Thu, 7 May 2020 19:06:57 +0200 Subject: usb: raw-gadget: support stalling/halting/wedging endpoints Raw Gadget is currently unable to stall/halt/wedge gadget endpoints, which is required for proper emulation of certain USB classes. This patch adds a few more ioctls: - USB_RAW_IOCTL_EP0_STALL allows to stall control endpoint #0 when there's a pending setup request for it. - USB_RAW_IOCTL_SET/CLEAR_HALT/WEDGE allow to set/clear halt/wedge status on non-control non-isochronous endpoints.
