USB: cdc-acm: Do not log urb submission errors on disconnect

2018-02-07T19:07:56+00:00

commit f0386c083c2ce85284dc0b419d7b89c8e567c09f upstream. When disconnected sometimes the cdc-acm driver logs errors like these: [20278.039417] cdc_acm 2-2:2.1: urb 9 failed submission with -19 [20278.042924] cdc_acm 2-2:2.1: urb 10 failed submission with -19 [20278.046449] cdc_acm 2-2:2.1: urb 11 failed submission with -19 [20278.049920] cdc_acm 2-2:2.1: urb 12 failed submission with -19 [20278.053442] cdc_acm 2-2:2.1: urb 13 failed submission with -19 [20278.056915] cdc_acm 2-2:2.1: urb 14 failed submission with -19 [20278.060418] cdc_acm 2-2:2.1: urb 15 failed submission with -19 Silence these by not logging errors when the result is -ENODEV.

USB: fix buffer overflows with parsing CDC headers

2017-11-30T08:35:54+00:00

Parsing CDC headers a buffer overflow cannot just be prevented by checking that the remainder of the buffer is longer than minimum length. The size of the fields to be parsed must be figured in, too. In newer kernels this issue has been fixed at a central location with commit 2e1c42391ff2556387b3cb6308b24f6f65619feb Author: Greg Kroah-Hartman Date: Thu Sep 21 16:58:48 2017 +0200 USB: core: harden cdc_parse_cdc_header on anything older the parsing had not been centralised, so a separate fix for each driver is necessary.

usb: cdc_acm: Add quirk for Elatec TWN3

2017-10-27T08:17:23+00:00

commit 765fb2f181cad669f2beb87842a05d8071f2be85 upstream. Elatec TWN3 has the union descriptor on data interface. This results in failure to bind the device to the driver with the following log: usb 1-1.2: new full speed USB device using streamplug-ehci and address 4 usb 1-1.2: New USB device found, idVendor=09d8, idProduct=0320 usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.2: Product: RFID Device (COM) usb 1-1.2: Manufacturer: OEM cdc_acm 1-1.2:1.0: Zero length descriptor references cdc_acm: probe of 1-1.2:1.0 failed with error -22 Adding the NO_UNION_NORMAL quirk for the device fixes the issue. `lsusb -v` of the device: Bus 001 Device 003: ID 09d8:0320 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 2 Communications bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 32 idVendor 0x09d8 idProduct 0x0320 bcdDevice 3.00 iManufacturer 1 OEM iProduct 2 RFID Device (COM) iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 67 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 250mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 2 Communications bInterfaceSubClass 2 Abstract (modem) bInterfaceProtocol 1 AT-commands (v.25ter) iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x83 EP 3 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 2 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 10 CDC Data bInterfaceSubClass 0 Unused bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 CDC Header: bcdCDC 1.10 CDC Call Management: bmCapabilities 0x03 call management use DataInterface bDataInterface 1 CDC ACM: bmCapabilities 0x06 sends break line coding and serial state CDC Union: bMasterInterface 0 bSlaveInterface 1 Device Status: 0x0000 (Bus Powered) Signed-off-by: Maksim Salau Acked-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: usbtmc: add missing endpoint sanity check

2017-04-22T05:15:05+00:00

commit 687e0687f71ec00e0132a21fef802dee88c2f1ad upstream. USBTMC devices are required to have a bulk-in and a bulk-out endpoint, but the driver failed to verify this, something which could lead to the endpoint addresses being taken from uninitialised memory. Make sure to zero all private data as part of allocation, and add the missing endpoint sanity check. Note that this also addresses a more recently introduced issue, where the interrupt-in-presence flag would also be uninitialised whenever the optional interrupt-in endpoint is not present. This in turn could lead to an interrupt urb being allocated, initialised and submitted based on uninitialised values.

USB: cdc-acm: fix TIOCMIWAIT

commit 18266403f3fe507f0246faa1d5432333a2f139ca upstream. The TIOCMIWAIT implementation would return -EINVAL if any of the three supported signals were included in the mask. Instead of returning an error in case TIOCM_CTS is included, simply drop the mask check completely, which is in accordance with how other drivers implement this ioctl.
