Here is the big USB patchset for the .34 merge window.
There are a few tty patches in here, as they made more sense to go
through here due to the usb-serial drivers they were changing.
Please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/gregkh/usb-2.6.git/
All of these patches have been in the linux-next and mm trees.
The full patches will be sent to the linux-usb mailing list, if anyone
wants to see them.
thanks,
greg k-h

To: Linus Torvalds, Andrew Morton; +Cc: linux-kernel, linux-usb
Here is the big USB merge for the 2.6.33-git tree.
Lots of different things here, mostly all just driver updates and a few
new additions. There was some prep work for future power api changes
done as well. All of the details are in the shortlog below.
Please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/gregkh/usb-2.6.git/
All of these patches have been in the linux-next and mm trees for a
while.
The full patches will be sent to the linux-usb mailing list, if anyone
wants to see them.
thanks,
greg k-h

This associates the usb_interface device with that minor number and creates the character device and announces it to the world. However, the driver's probe function is called before the new usb_interface is added to the driver's klist_devices. ... and what's even scarier is that that commit is marked for stable too.

Confirmed. With that commit reverted, everything works fine again. So it's definitely a2582bd478c13c574d4c16ef1209d333f2a25935, although I have no idea _why_ it causes problems. One thing I note is that it literally changed semantics, as per the comment in there. It used to be: This walks the driver device list and returns a pointer to the interface with the matching minor. and after that it is This walks the bus device list and returns a pointer to the interface with the matching minor. Notice the "driver device list" -> "bus device list" change. Also notice that the minor number of my 'lp0' device is zero, so I could easily imagine that some device without a driver at all or whatever will have a zero there, and then it would return the wrong device entirely. So I really think that commit is very suspect. Not matching against the driver that we passed in looks like some total screwup. But I don't know the code or the use. I do know that reverting it fixes it. Linus ^ permalink raw reply [flat|nested] 18+ messages in thread

Sorry for breaking your printer. There is both USB_MAJOR and USB_DEVICE_MAJOR. I haven't investigated it in great detail yet, but that seems likely to be the issue. I'll clean up the patch. And yes, it should definitely not be going into stable yet. Revert for now and I'll resubmit.

And yes, it should definitely not be going into stable yet. Revert for now and I'll resubmit. Here is a cleaned up patch that matches against minor and driver, not just minor.

From 4441c99c80d8298a99b6f2fbd4ece9d3cfe7fd4d Mon Sep 17 00:00:00 2001 From: Russ Dill <Russ.Dill@gmail.com> Date: Wed, 18 Nov 2009 10:31:27 -0700 Subject: [PATCH] Close usb_find_interface race v2 USB drivers that create character devices call usb_register_dev in their probe function. This associates the usb_interface device with that minor number and creates the character device and announces it to the world. However, the driver's probe function is called before the new usb_interface is added to the driver's klist_devices. This is a problem because userspace will respond to the character device creation announcement by opening the character device. The driver's open function will the call usb_find_interface to find the usb_interface associated with that minor number. usb_find_interface will walk the driver's list of devices and find the usb_interface with the matching minor number. Because the announcement happens before the usb_interface is added to the driver's klist_devices, a race condition exists. A straightforward fix is to walk the list of devices on usb_bus_type instead since the device is added to that list before the announcement occurs. bus_find_device calls get_device to bump the reference count on the found device. It is arguable that the reference count should be dropped by the caller of usb_find_interface instead of usb_find_interface, however, the current users of usb_find_interface do not expect this. The original version of this patch only matched against minor number instead of driver and minor number. This version matches against both.
