  • d883f52e1   usb: devio: Add ioctl to disallow detaching kernel USB drivers. ... Browse Code »

    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
    ...
    Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd

    $ usb-devices
    ...
    C: #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
    I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=02 Driver=usbhid

    $ sudo ./usbdevfs-drop-permissions /dev/bus/usb/001/002
    OK: privileges dropped!
    Available options:
    [0] Exit now
    [1] Reset device. Should fail if device is in use
    [2] Claim 4 interfaces. Should succeed where not in use
    [3] Narrow interface permission mask
    Which option shall I run?: 1
    ERROR: USBDEVFS_RESET failed! (1 - Operation not permitted)
    Which test shall I run next?: 2
    ERROR claiming if 0 (1 - Operation not permitted)
    ERROR claiming if 1 (1 - Operation not permitted)
    ERROR claiming if 2 (1 - Operation not permitted)
    ERROR claiming if 3 (1 - Operation not permitted)
    Which test shall I run next?: 0

    After unbinding usbhid:

    $ usb-devices
    ...
    I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=02 Driver=(none)

    $ sudo ./usbdevfs-drop-permissions /dev/bus/usb/001/002
    ...
    Which option shall I run?: 2
    OK: claimed if 0
    ERROR claiming if 1 (1 - Operation not permitted)
    ERROR claiming if 2 (1 - Operation not permitted)
    ERROR claiming if 3 (1 - Operation not permitted)
    Which test shall I run next?: 1
    OK: USBDEVFS_RESET succeeded
    Which test shall I run next?: 0

    After unbinding usbhid and restricting the mask:

    $ sudo ./usbdevfs-drop-permissions /dev/bus/usb/001/002
    ...
    Which option shall I run?: 3
    Insert new mask: 0
    OK: privileges dropped!
    Which test shall I run next?: 2
    ERROR claiming if 0 (1 - Operation not permitted)
    ERROR claiming if 1 (1 - Operation not permitted)
    ERROR claiming if 2 (1 - Operation not permitted)
    ERROR claiming if 3 (1 - Operation not permitted)

  • a6d6fc2b6   usbip: move usbip_protocol.txt to Documentation ... Browse Code »

    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].

  • bf5ce5bf3   usb: core: lpm: fix usb3_hardware_lpm sysfs node ... Browse Code »

    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").

    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.

  • d6d22922d   usb: gadget: rndis: remove the limit of available rndis connections ... Browse Code »

    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.

  • e3aa205aa   Documentation usb serial: fixed how to provide vendor and product id ... Browse Code »

    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.
    Please note that the old one still works (if compiled as module).

    usb: patches for v3.20 merge window

    Here's the big pull request for Gadgets and PHYs. It's
    a total of 217 non-merge commits with pretty much everything
    being touched.

    The most important bits are a ton of new documentation for
    almost all usb gadget functions, a new isp1760 UDC driver,
    several improvements to the old net2280 UDC driver, and
    some minor tracepoint improvements to dwc3.

    Other than that, a big list of minor cleanups, smaller bugfixes
    and new features all over the place.
