2012-10-25USB: qcserial: fix interface-data memory leak in error pathJohan Hovold
Move interface data allocation to attach so that it is deallocated should usb-serial probe fail. Signed-off-by: Johan Hovold <jhovold@gmail.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-10-25USB: usb-wwan: fix multiple memory leaks in error pathsJohan Hovold
Fix port-data memory leak in usb-serial probe error path by moving port data allocation to port_probe. Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect with a port_remove hook") port data is deallocated in port_remove. This leaves a possibility for memory leaks if usb-serial probe fails after attach but before the port in question has been successfully registered. Note that this patch also fixes two additional memory leaks in the error path of attach should port initialisation fail for any port as the urbs were never freed and neither was the data of any of the successfully initialised ports. Compile-only tested. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Now that the dbg() macro is no longer being used in the driver, the debug module parameter doesn't do anything at all. So remove it so as to not confuse people.

2012-08-16USB: qcserial: fix port handling on Gobi 1K and 2K+Dan Williams
Bjorn's latest patchset does break Gobi 1K and 2K because on both devices as it claims usb interface 0. That's because usbif 0 is not handled in the switch statement, and thus the if0 gets claimed when it should not. So let's just make things even simpler yet, and handle both the 1K and 2K+ cases separately. This patch should not affect the new Sierra device support, because those devices are matched via interface-specific matching and thus should never hit the composite code.

2012-08-10usb: usb_wwan: replace release and disconnect with a port_remove hookBjørn Mork
Doing port specific cleanup in the .port_remove hook is a lot simpler and safer than doing it in the USB driver .release or .disconnect methods. The removal of the port from the usb-serial bus will happen before the USB driver cleanup, so we must be careful about accessing port specific driver data from any USB driver functions. This problem surfaced after the commit 0998d0631 device-core: Ensure drvdata = NULL when no driver is bound which turned the previous unsafe access into a reliable NULL pointer dereference.

2012-07-16USB: qcserial: adding Sierra Wireless devicesBjørn Mork
The QMI mode of the Sierra Wireless MC7710 is close to a Gobi device, and also identified as one by the Windows drivers provided by Sony. The serial interfaces are the same as for any other Gobi module, but the USB interface layout is different: 0: DM/DIAG (also present in bootloader mode) 2: NMEA 3: AT-capable modem port 8: QMI/net 19: QMI/net (not always present) 20: QMI/net (not always present) Note in particular that the NMEA and AT ports are reversed compared to a Gobi 2k+ device, and that the DM port appears as a QDL port in bootloader mode using the same device ID. The Sony driver also document two new devices with standard Gobi 2k+ layout (1199:68a5, 1199:68a9) having a QDL mode (1199:68a4, 1199:68a8). Adding these as well. Lenovo Windows drivers document the USB interface layout for a few additional Sierra Wireless devices. Adding these while at it: - MC7770 (1199:901b) with standard Gobi 2k+ layout - MC7700 (0f3d:68a2) with the same layout as MC7710 - MC7750 (114f:68a2) with the same layout as MC7710 - EM7700 (1199:901c) with the same layout as MC7710 Cc: Anton Samokhvalov <pg83@yandex.ru> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.

2012-05-07usb-serial: clean up unneeded PM-related fieldsAlan Stern
This patch (as1551) cleans up the PM-related entries in the usb_driver structures of the various USB serial driver modules. Those entries are now filled in by the usb-serial core during driver registration, so they don't need to be initialized explicitly in the source code. The same is true of the one remaining no_dynamic_id entry. reset_resume remains a small problem, because the serial core doesn't support it. The patch ignores these entries.

Gobi 1000 devices have a different port layout, which wasn't respected by the current driver, and thus it grabbed the QMI/net port. In the near future we'll be attaching another driver to the QMI/net port for these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver doesn't claim them. This patch also prevents qcserial from binding to interfaces 0 and 1 on 1K devices because those interfaces do not respond.

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-10-31usb: Add module.h to drivers/usb consumers who really use it.Paul Gortmaker
The situation up to this point meant that module.h was pretty much everywhere, regardless of whether you asked for it or not. We are fixing that, so give the USB folks who want it an actual include of it. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2010-10-22USB: qcserial: Enable Diagnostics Monitor and GPS ports on Gobi 2000Matthias G. Eckermann
this patch to qcserial.c enables the Diagnostics Monitor and NMEA GPS ports on Qualcomm Gobi 2000 devices. A Gobi 2000 device will provide 3 serial ports: # /dev/ttyUSB0 -> Diagnostics # /dev/ttyUSB1 -> 3G Modem # /dev/ttyUSB2 -> NMEA GPS port * The Diagnostics Monitor uses Qualcomm's DM protocol; I used libqcdm (ModemManager) to talk to it, found it working, but at least DM commands 12 and 64 are not implemented on my device (Gobi 2000 built into Thinkpad x100e). * Functionality of the 3G Modem port remains unchanged. * The GPS port and how to enable it has been confirmed now in the Gobi 3000 source code at: https://www.codeaurora.org/patches/quic/gobi/ Enable/disable GPS via: echo "\$GPS_START" > /dev/ttyUSB2 # use GPS echo "\$GPS_STOP" > /dev/ttyUSB2 Signed-off-by: Matthias G.

Add ids for Qualcomm Gobi 2000 QDL and Modem modes. Gobi 2000 has a single altsetting in QDL mode, so adapt code to handle that. Firmware upload protocol is also slightly different, with an additional firmware file. However, qcserial doesn't handle firmware uploading. Tested on Lenovo Thinkpad T510.

The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make the initialization data also constant.
