2012-09-11USB: option: replace ZTE K5006-Z entry with vendor class ruleBjørn Mork
Fix the ZTE K5006-Z entry so that it actually matches anything commit f1b5c997 USB: option: add ZTE K5006-Z added a device specific entry assuming that the device would use class/subclass/proto == ff/ff/ff like other ZTE devices.

2012-09-10USB: ftdi_sio: do not claim CDC ACM functionBjørn Mork
The Microchip vid:pid 04d8:000a is used for their CDC ACM demo firmware application. This is a device with a single function conforming to the CDC ACM specification and with the intention of demonstrating CDC ACM class firmware and driver interaction. The demo is used on a number of development boards, and may also be used unmodified by vendors using Microchip hardware. Some vendors have re-used this vid:pid for other types of firmware, emulating FTDI chips. Attempting to continue to support such devices without breaking class based applications that by matching on interface class/subclass/proto being ff/ff/00. I have no information about the actual device or interface descriptors, but this will at least make the proper CDC ACM devices work again. Anyone having details of the offending device's descriptors should update this entry with the details.

Commit b69cc672052540 added support for the E-861. After acquiring a C-867, I realised that every Physik Instrumente's device has a different PID. They are listed in the Windows device driver's .inf file. So here are all PIDs for the current (and probably future) USB devices from Physik Instrumente.

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: resume/suspend can be called after port is goneBjørn Mork
We cannot unconditionally access any usb-serial port specific data from the interface driver. Both supending and resuming may happen after the port has been removed and portdata is freed. Treat ports with no portdata as closed ports to avoid a NULL pointer dereference on resume. No need to kill URBs for removed ports on suspend, avoiding the same NULL pointer reference there.

2012-08-10usb: serial: prevent suspend/resume from racing against probe/removeBjørn Mork
Some usb-serial drivers may access port data in their suspend/ resume functions. Such drivers must always verify the validity of the data as both suspend and resume can be called both before usb_serial_device_probe and after usb_serial_device_remove. But the port data may be invalidated during port_probe and port_remove. This patch prevents the race against suspend and resume by disabling suspend while port_probe or port_remove is running.

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.

2012-06-13USB: serial-generic: use a single set of device IDsAlan Stern
The usb-serial-generic driver uses different device IDs for its USB matching and its serial matching. This can lead to problems: The driver can end up getting bound to a USB interface without being allowed to bind to the corresponding serial port. This patch (as1557) fixes the problem by using the same device ID table (the one that can be altered by the "vendor=" and "product=" module parameters) for both purposes. The unused table is removed. Now the driver will bind only to the intended devices.

2012-06-13USB: serial: Enforce USB driver and USB serial driver matchBjørn Mork
We need to make sure that the USB serial driver we find matches the USB driver whose probe we are currently executing. Otherwise we will end up with USB serial devices bound to the correct serial driver but wrong USB driver. An example of such cross-probing, where the usbserial_generic USB driver has found the sierra serial driver: May 29 18:26:15 nemi kernel: [ 4442.559246] usbserial_generic 4-4:1.0: Sierra USB modem converter detected May 29 18:26:20 nemi kernel: [ 4447.556747] usbserial_generic 4-4:1.2: Sierra USB modem converter detected May 29 18:26:25 nemi kernel: [ 4452.557288] usbserial_generic 4-4:1.3: Sierra USB modem converter detected sysfs view of the same problem: bjorn@nemi:~$ ls -l /sys/bus/usb/drivers/sierra/ total 0 --w------- 1 root root 4096 May 29 18:23 bind lrwxrwxrwx 1 root root 0 May 29 18:23 module -> ../../../../module/usbserial --w------- 1 root root 4096 May 29 18:23 uevent --w------- 1 root root 4096 May 29 18:23 unbind bjorn@nemi:~$ ls -l /sys/bus/usb-serial/drivers/sierra/ total 0 --w------- 1 root root 4096 May 29 18:23 bind lrwxrwxrwx 1 root root 0 May 29 18:23 module -> ../../../../module/sierra -rw-r--r-- 1 root root 4096 May 29 18:23 new_id lrwxrwxrwx 1 root root 0 May 29 18:32 ttyUSB0 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.0/ttyUSB0 lrwxrwxrwx 1 root root 0 May 29 18:32 ttyUSB1 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.2/ttyUSB1 lrwxrwxrwx 1 root root 0 May 29 18:32 ttyUSB2 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.3/ttyUSB2 --w------- 1 root root 4096 May 29 18:23 uevent --w------- 1 root root 4096 May 29 18:23 unbind bjorn@nemi:~$ ls -l /sys/bus/usb/drivers/usbserial_generic/ total 0 lrwxrwxrwx 1 root root 0 May 29 18:33 4-4:1.0 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.0 lrwxrwxrwx 1 root root 0 May 29 18:33 4-4:1.2 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.2 lrwxrwxrwx 1 root root 0 May 29 18:33 4-4:1.3 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.3 --w------- 1 root root 4096 May 29 18:33 bind lrwxrwxrwx 1 root root 0 May 29 18:33 module -> ../../../../module/usbserial --w------- 1 root root 4096 May 29 18:22 uevent --w------- 1 root root 4096 May 29 18:33 unbind bjorn@nemi:~$ ls -l /sys/bus/usb-serial/drivers/generic/ total 0 --w------- 1 root root 4096 May 29 18:33 bind lrwxrwxrwx 1 root root 0 May 29 18:33 module -> ../../../../module/usbserial -rw-r--r-- 1 root root 4096 May 29 18:33 new_id --w------- 1 root root 4096 May 29 18:22 uevent --w------- 1 root root 4096 May 29 18:33 unbind So we end up with a mismatch between the USB driver and the USB serial driver. The reason for the above is simple: The USB driver probe will succeed if *any* registered serial driver matches, and will use that serial driver for all serial driver functions. This makes ref counting go wrong. We count the USB driver as used, but not the USB serial driver.
