2008-12-17USB: skip Set-Interface(0) if already in altsetting 0Alan Stern
When a driver unbinds from an interface, usbcore always sends a Set-Interface request to reinstall altsetting 0. Unforunately, quite a few devices have buggy firmware that crashes when it receives this request. To avoid such problems, this patch (as1180) arranges to send the Set-Interface request only when the interface is not already in altsetting 0.

There's a bug in the usbmon binary reader: When using read() to fetch the packets and a packet's data is partially read, the next read call will once again return up to len_cap bytes of data. The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid USB subsystem hang symptom. The USB subsystem hang symptom is observed when the system has multiple USB devices connected to it. In some cases a USB hub may be required to observe this symptom. This patch works around the problem by correcting the internal register setting that will help by changing the behavior of the internal logic to avoid the USB subsystem hang issue. The change in the behavior of the logic does not impact the normal operation of the USB subsystem.

2008-11-14CRED: Wrap task credential accesses in the USB driverDavid Howells
Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

2008-11-13USB: gadget: cdc-acm deadlock fixDavid Brownell
This fixes a deadlock appearing with some USB peripheral drivers when running CDC ACM gadget code. The newish (2.6.27) CDC ACM event notification mechanism sends messages (IN to the host) which are short enough to fit in most FIFOs. That means that with some peripheral controller drivers (evidently not the ones used to verify the notification code!!) the completion callback can be issued before queue() returns. The deadlock would come because the completion callback and the event-issuing code shared a spinlock. Fix is trivial: drop that lock while queueing the message.

2008-11-13USB: EHCI: fix divide-by-zero bugAlan Stern
This patch (as1164) fixes a bug in the EHCI scheduler. The interval value it uses is already in linear format, not logarithmically coded. The existing code can sometimes crash the system by trying to divide by zero.

2008-11-13USB: EHCI: fix handling of dead controllersAlan Stern
This patch (as1165) makes a few small changes in the logic used by ehci-hcd when it encounters a controller error: Instead of printing out the masked status, it prints the original status as read directly from the hardware. It doesn't check for the STS_HALT status bit before taking action. The mere fact that the STS_FATAL bit is set means that something bad has happened and the controller needs to be reset. With the old code this test could never succeed because the STS_HALT bit was masked out from the status. I anticipate that this will prevent the occasional "irq X: nobody cared" problem people encounter when their EHCI controllers die.
