* USB: remove err() macro from usb core codeGreg Kroah-Hartman2008-10-171-2/+3
| | | | | | | | | USB should not be having it's own printk macros, so remove err() and use the system-wide standard of dev_err() wherever possible. In the few places that will not work out, use a basic printk(). Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* device create: usb: convert device_create_drvdata to device_createGreg Kroah-Hartman2008-10-161-3/+3
| | | | | | | | Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* device create: usb: convert device_create to device_create_drvdataGreg Kroah-Hartman2008-07-211-2/+3
| | | | | | | | device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: usb dev_name() instead of dev->bus_idKay Sievers2008-07-211-5/+5
| | | | | | | | The bus_id field is going away, use the dev_name() function instead. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* usbcore: cdev lock_kernel() pushdownJonathan Corbet2008-06-201-0/+3
| | | | | | | usb_open() is protected by a down_read(&minor_rwsem), but I'm not sure I trust it to protect everything including subsidiary open() functions. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
* USB: mark USB drivers as being GPL onlyGreg Kroah-Hartman2008-02-011-2/+2
| | | | | | | | | | | | Over two years ago, the Linux USB developers stated that they believed there was no way to create a USB kernel driver that was not under the GPL. This patch moves the USB apis to enforce that decision. There are no known closed source USB drivers in the wild, so this patch should cause no problems.

* USB: prevent char device open/deregister raceAlan Stern2007-07-121-16/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as908) adds central protection in usbcore for the prototypical race between opening and unregistering a char device. The spinlock used to protect the minor-numbers array is replaced with an rwsem, which can remain locked across a call to a driver's open() method. This guarantees that open() and deregister() will be mutually exclusive. The private locks currently used in several individual drivers for this purpose are no longer necessary, and the patch removes them. The following USB drivers are affected: usblcd, idmouse, auerswald, legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and usb-skeleton. As a side effect of this change, usb_deregister_dev() must not be called while holding a lock that is acquired by open(). Unfortunately a number of drivers do this, but luckily the solution is simple: call usb_deregister_dev() before acquiring the lock. In addition to these changes (and their consequent code simplifications), the patch fixes a use-after-free bug in adutux and a race between open() and release() in iowarrior.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
