usb: gadget: f_fs: Assorted buffer overflow checks.

2017-02-09T07:08:30Z

commit 83e526f2a2fa4b2e82b6bd3ddbb26b70acfa8947 upstream. OS descriptor head, when flagged as provided, is accessed without checking if it fits in provided buffer. Verify length before access. Also, there are other places where buffer length it checked after accessing offsets which are potentially past the end. Check buffer length before as well to fail cleanly.

usb: musb: Fix host mode error -71 regression

2017-02-09T07:08:30Z

commit 407788b51db6f6aab499d02420082f436abf3238 upstream. Commit 467d5c980709 ("usb: musb: Implement session bit based runtime PM for musb-core") started implementing musb generic runtime PM support by introducing devctl register session bit based state control. This caused a regression where if a USB mass storage device is connected to a USB hub, we can get: usb 1-1: reset high-speed USB device number 2 using musb-hdrc usb 1-1: device descriptor read/64, error -71 usb 1-1.1: new high-speed USB device number 4 using musb-hdrc This is because before the USB storage device is connected, musb is in OTG_STATE_A_SUSPEND. And we currently only set need_finish_resume in musb_stage0_irq() and the related code calling finish_resume_work in musb_resume() and musb_runtime_resume() never gets called. To fix the issue, we can call schedule_delayed_work() directly in musb_stage0_irq() to have finish_resume_work run. And we should no longer never get interrupts when when suspended. We have changed musb to no longer need pm_runtime_irqsafe(). The need_finish_resume flag was added in commit 9298b4aad37e ("usb: musb: fix device hotplug behind hub") and no longer applies as far as I can tell. So let's just remove the earlier code that no longer is needed.

USB: Add quirk for WORLDE easykey.25 MIDI keyboard

2017-02-09T07:08:30Z

commit d9b2997e4a0a874e452df7cdd7de5a54502bd0aa upstream. Add a quirk for WORLDE easykey.25 MIDI keyboard (idVendor=0218, idProduct=0401). The device reports that it has config string descriptor at index 3, but when the system selects the configuration and tries to get the description, it returns a -EPROTO error, the communication restarts and this keeps repeating over and over again. Not requesting the string descriptor makes the device work correctly. Relevant info from Wireshark: [...] CONFIGURATION DESCRIPTOR bLength: 9 bDescriptorType: 0x02 (CONFIGURATION) wTotalLength: 101 bNumInterfaces: 2 bConfigurationValue: 1 iConfiguration: 3 Configuration bmAttributes: 0xc0 SELF-POWERED NO REMOTE-WAKEUP 1... .... = Must be 1: Must be 1 for USB 1.1 and higher .1.. .... = Self-Powered: This device is SELF-POWERED ..0. .... = Remote Wakeup: This device does NOT support remote wakeup bMaxPower: 50 (100mA) [...] 45 0.369104 host 2.38.0 USB 64 GET DESCRIPTOR Request STRING [...] URB setup bmRequestType: 0x80 1... .... = Direction: Device-to-host .00. .... = Type: Standard (0x00) ...0 0000 = Recipient: Device (0x00) bRequest: GET DESCRIPTOR (6) Descriptor Index: 0x03 bDescriptorType: 0x03 Language Id: English (United States) (0x0409) wLength: 255 46 0.369255 2.38.0 host USB 64 GET DESCRIPTOR Response STRING[Malformed Packet] [...] Frame 46: 64 bytes on wire (512 bits), 64 bytes captured (512 bits) on interface 0 USB URB [Source: 2.38.0] [Destination: host] URB id: 0xffff88021f62d480 URB type: URB_COMPLETE ('C') URB transfer type: URB_CONTROL (0x02) Endpoint: 0x80, Direction: IN Device: 38 URB bus id: 2 Device setup request: not relevant ('-') Data: present (0) URB sec: 1484896277 URB usec: 455031 URB status: Protocol error (-EPROTO) (-71) URB length [bytes]: 0 Data length [bytes]: 0 [Request in: 45] [Time from request: 0.000151000 seconds] Unused Setup Header Interval: 0 Start frame: 0 Copy of Transfer Flags: 0x00000200 Number of ISO descriptors: 0 [Malformed Packet: USB] [Expert Info (Error/Malformed): Malformed Packet (Exception occurred)] [Malformed Packet (Exception occurred)] [Severity level: Error] [Group: Malformed] Signed-off-by: Lukáš Lalinský Signed-off-by: Greg Kroah-Hartman

USB: serial: pl2303: add ATEN device ID

2017-02-09T07:08:29Z

commit d07830db1bdb254e4b50d366010b219286b8c937 upstream. Seems that ATEN serial-to-usb devices using pl2303 exist with different device ids. This patch adds a missing device ID so it is recognised by the driver. Signed-off-by: Marcel J.E. Mol Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: qcserial: add Dell DW5570 QDL

2017-02-09T07:08:29Z

commit 24d615a694d649aa2e167c3f97f62bdad07e3f84 upstream. The Dell DW5570 is a re-branded Sierra Wireless MC8805 which will by default boot with vid 0x413c and pid 0x81a3. When triggered QDL download mode, the device switches to pid 0x81a6 and provides the standard TTY used for firmware upgrade.

USB: serial: ch341: fix modem-control and B0 handling

2017-01-19T19:18:04Z

commit 030ee7ae52a46a2be52ccc8242c4a330aba8d38e upstream. The modem-control signals are managed by the tty-layer during open and should not be asserted prematurely when set_termios is called from driver open. Also make sure that the signals are asserted only when changing speed from B0.

xhci: fix deadlock at host remove by running watchdog correctly

2017-01-19T19:18:02Z

commit d6169d04097fd9ddf811e63eae4e5cd71e6666e2 upstream. If a URB is killed while the host is removed we can end up in a situation where the hub thread takes the roothub device lock, and waits for the URB to be given back by xhci-hcd, blocking the host remove code. xhci-hcd tries to stop the endpoint and give back the urb, but can't as the host is removed from PCI bus at the same time, preventing the normal way of giving back urb. Instead we need to rely on the stop command timeout function to give back the urb. This xhci_stop_endpoint_command_watchdog() timeout function used a XHCI_STATE_DYING flag to indicate if the timeout function is already running, but later this flag has been taking into use in other places to mark that xhci is dying. Remove checks for XHCI_STATE_DYING in xhci_urb_dequeue. We are still checking that reading from pci state does not return 0xffffffff or that host is not halted before trying to stop the endpoint. This whole area of stopping endpoints, giving back URBs, and the wathdog timeout need rework, this fix focuses on solving a specific deadlock issue that we can then send to stable before any major rework.

USB: serial: ch341: fix open and resume after B0

2017-01-19T19:18:02Z

commit a20047f36e2f6a1eea4f1fd261aaa55882369868 upstream. The private baud_rate variable is used to configure the port at open and reset-resume and must never be set to (and left at) zero or reset-resume and all further open attempts will fail.

USB: serial: ch341: fix control-message error handling

2017-01-19T19:18:01Z

commit 2d5a9c72d0c4ac73cf97f4b7814ed6c44b1e49ae upstream. A short control transfer would currently fail to be detected, something which could lead to stale buffer data being used as valid input. Check for short transfers, and make sure to log any transfer errors. Note that this also avoids leaking heap data to user space (TIOCMGET) and the remote device (break control).
