2016-03-05usb: devio: Add ioctl to disallow detaching kernel USB drivers.Reilly Grant1-0/+120
The new USBDEVFS_DROP_PRIVILEGES ioctl allows a process to voluntarily relinquish the ability to issue other ioctls that may interfere with other processes and drivers that have claimed an interface on the device. This commit also includes a simple utility to be able to test the ioctl, located at Documentation/usb/usbdevfs-drop-permissions.c Example (with qemu-kvm's input device): $ lsusb ...

Many changes to the host side implementation of dwc2 have been done by Douglas Anderson. We also have USB 3.1 support added to the Gadget Framework and, because of that work, dwc3 got support to Synopsys new DWC_usb31 IP core. Other than these 2 important series, we also have the usual collection of non-critical fixes, Documentation updates, and minor changes all over the place.

2016-03-03usbip: move usbip_protocol.txt to DocumentationChristian Lamparter1-0/+358
The usbip_protocol.txt, a document which describes usbip's inner workings is currently located in the projects source directory (drivers/usb/usbip/...). This patch moves it to Documentation/usb. This discussion was brought up by Guy Harris [0] during the review of the USBIP dissector I wrote. For anyone interested: support is available with the latest wireshark master/dev tree. Simply select a packet from the usbip's tcp-stream you are intrested on and select the USBIP as the protocol in the "Decode As" dialog box [1].

Yoshihiro Shimoda gives us support for a new USB3 peripheral controller from Renesas. Other than these, the usual misc fixes all over the place.

2015-12-01usb: core: lpm: fix usb3_hardware_lpm sysfs nodeLu Baolu1-5/+6
Commit 655fe4effe0f ("usbcore: add sysfs support to xHCI usb3 hardware LPM") introduced usb3_hardware_lpm sysfs node. This doesn't show the correct status of USB3 U1 and U2 LPM status. This patch fixes this by replacing usb3_hardware_lpm with two nodes, usb3_hardware_lpm_u1 (for U1) and usb3_hardware_lpm_u2 (for U2), and recording the U1/U2 LPM status in right places. This patch should be back-ported to kernels as old as 4.3, that contains Commit 655fe4effe0f ("usbcore: add sysfs support to xHCI usb3 hardware LPM").

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v4.3 merge window New support for Allwinne SoC on the MUSB driver has been added to the list of glue layers. MUSB also got support for building all DMA engines in one binary; this will be great for distros. DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on tracing to debug DWC3. There was also a fix for memory corruption with EP0 when maxpacket size transfers are > 512 bytes. Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are now required to set these flags up when adding endpoints to the framework. Other than these, we have the usual set of miscelaneous cleanups and minor fixes.

2015-05-07usb: gadget: rndis: remove the limit of available rndis connectionsAndrzej Pietrasiewicz1-2/+0
RNDIS function has a limitation on the number of allowed instances. So far it has been RNDIS_MAX_CONFIGS, which happens to be one. In order to eliminate this kind of arbitrary limitation we should not preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params instances but instead allow allocating them on demand. This patch allocates struct rndis_params on demand in rndis_register(). Coversly, the structure is free()'d in rndis_deregister(). If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which is the same behaviour as before, but the moment of creation is delayed until struct rndis_params is actually allocated. rnids_init() and rndis_exit() have nothing to do, so they are eliminated.

2015-05-07Documentation usb serial: fixed how to provide vendor and product idH. Nikolaus Schaller1-5/+7
While trying to test a Cinterion GSM/GPS/3G module I had reconfigured the USB interface by mistake and therefore needed to run a different USB driver than CDC-ACM. It turned out that I need the "usbserial" driver. This file is an official description how to use it: Documentation/usb/usb-serial.txt But it is outdated. The parameters vendor= and product= have been superseded by a /sys interface. Here was the solution: https://bbs.archlinux.org/viewtopic.php?id=175499 insmod usbserial vendor=0x#### product=0x#### becomes (first #### is vendor, second is product) modprobe usbserial echo #### #### >/sys/bus/usb-serial/drivers/generic/new_id This patch changes the documentation file to describe the modern variant.
