2010-03-19USB: serial: use port endpoint size to determine if ep is availableJohan Hovold
It is possible to have a multi-port device with a port lacking an in or out bulk endpoint. Only checking for num_bulk_in or num_bulk_out is thus not sufficient to determine whether a specific port has an in or out bulk endpoint. This fixes potential null pointer dereferences in the generic open and write routines, as well as access to uninitialised fifo in write_room and chars_in_buffer. Also let write fail with ENODEV (instead of 0) on missing out endpoint (also on zero-length writes). Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

qcaux: add driver for QCDM-capable ports on various devices Many Qualcomm-based devices provide a CDC-ACM port which accepts normal AT commands and PPP connections. But they only provide one which makes status or signal strength requests impossible while PPP is active. They also provide secondary USB interfaces that talk the Qualcomm Diagnostic Monitor (QCDM) protocol which can be used for status and strength. Make those QCDM ports accessible.

2010-03-02USB: pl2303: initial TIOCGSERIAL supportJohn Tsiombikas
I've got a trivial patch for the pl2303 driver, that's what I needed to make the wacom serial tablet driver work properly. It uses the TIOCGSERIAL ioctl to determine if it's talking to a serial device or not, which I gather is rather common, but the pl2303 driver didn't implement that ioctl. Here's a patch, I'm not sure it's absolutely correct, I mostly looked at other similar usbserial drivers to see what I must do, but it works for me.

2010-03-02USB: remove references to port->port.count from the serial driversAlan Stern
This patch (as1344) removes references to port->port.count from the USB serial drivers. Now that serial ports are properly reference counted, port.count checking is unnecessary and incorrect. Drivers should assume that the port is in use from the time the open method runs until the close method is called.

A crash has been reported with sierra driver on disconnect with Ubuntu/Lucid distribution based on kernel-2.6.32.

This patch modifies sierra_indat_callback() function to check for NULL tty structure pointer. This modification prevents a crash from happening when the device is disconnected.

2010-03-02USB: serial: add support for serial port on the moschip 7715Mike Dunn
Add support for the serial port on devices based on the MosChip 7715, which provides a serial and parallel port on a single usb interface. This is added to the existing driver for the Moschip 7720 dual serial port device. The 7715 is very similiar to the 7720, requiring only the addition of a calc_num_ports() function, a separate interrupt-in endpoint callback, and some manipulation of the port pointers added to the attach() function to correct the fact that the usbserial core erroneously assigns the first bulk in/out endpoint pair to the serial port (the 7715 uses these for its parallel port). There is no support for the 7715's parallel port yet. Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-02USB: io_edgeport: eliminate get_string()Dan Carpenter
Johan Hovold points out that get_string() is basically just a re-implimentation of usb_string(). It is also buggy. It does DMA on the stack and it doesn't handle negative returns from usb_get_descriptor(). Plus unicode_to_ascii() is a rubbish function and moving to usb_string() avoids using it. Let's eliminate get_string() entirely.

The 4G XS Stick W14 seems to not understand RTS/DTR setting in option_send_setup causing long timeouts on any open() which disturbs a lot of well-known userspace applications like minicom or ModemManager.

2010-03-02USB: serial: option.c: Add blacklisting infrastructure for special device ↵Gernot Hillier
handling As suggested by Matthias Urlichs, this patch adds a somehow generic mechanism for special handling of devices which don't support all bits expected by this driver. The blacklisting code is heavily stolen from sierra.c, but extended to support different special cases. For now, one case is implemented (OPTION_BLACKLIST_SENDSETUP), targeted at the 4G W14 device: devices which don't understand the setting of RTS/DTR in option_send_setup() causing a USB timeout of 5 s in any userspace open() which leads to errors in most userspace applications. In addition, I prepared another case for devices with interfaces which shall not be accessed by this driver (targeted at the D-Link DWM 652). However, OPTION_BLACKLIST_RESERVED_IF is not fully implemented yet as I have no device to test this. Anyone volunteering to help here? If not, I'll contact the guys who added D-Link DWM 652 support soon. Signed-off-by: Gernot Hillier <gernot@hillier.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
