2007-07-12ehci-hub: improved over-current recoveryChristian Engelmayer
According to the USB Specification Revision 2.0 chapter 11.12.5 a hub experiencing an over-current condition must place all affected ports in the powered-off state. It seems that some root hubs need port power to be cycled by software in order to get back to normal functionality after an over-current condition ... like the EHCI implementation on an MPC8343E.

2007-07-12USB: usb-storage: use kthread_stop() for the control threadAlan Stern
This patch (as923) makes usb-storage's control thread use kthread_should_stop()/kthread_stop(). The scanning thread can't be similarly converted until the core kthread implementation allows threads to call do_exit(). The advantage of this change is that we can now be certain the control thread has terminated before storage_disconnect() returns. This will simplify the locking requirements when autosuspend support is added.

2007-07-12USB: add power/persist device attributeAlan Stern
This patch (as920) adds an extra level of protection to the USB-Persist facility. Now it will apply by default only to hubs; for all other devices the user must enable it explicitly by setting the power/persist device attribute. The disconnect_all_children() routine in hub.c has been removed and its code placed inline. This is the way it was originally as part of hub_pre_reset(); the revised usage in hub_reset_resume() is sufficiently different that the code can no longer be shared. Likewise, mark_children_for_reset() is now inline as part of hub_reset_resume(). The end result looks much cleaner than before. The sysfs interface is updated to add the new attribute file, and there are corresponding documentation updates.

2007-07-12USB: unify reset_resume and normal resumeAlan Stern
This patch (as919) unifies the code paths used for normal resume and for reset-resume. Earlier I had failed to note a section in the USB spec which requires the host to resume a suspended port before resetting it if the attached device is enabled for remote wakeup. Since the port has to be resumed anyway, we might as well reuse the existing code. The main changes are: usb_reset_suspended_device() is eliminated. usb_root_hub_lost_power() is moved down next to the hub_reset_resume() routine, to which it is logically related. finish_port_resume() does a port reset() if the device's reset_resume flag is set. usb_port_resume() doesn't check whether the port is initially enabled if this is a USB-Persist sort of resume. Code to perform the port reset is added to the resume pathway for the non-CONFIG_USB_SUSPEND case.

2007-07-12USB: add reset_resume methodAlan Stern
This patch (as918) introduces a new USB driver method: reset_resume. It is called when a device needs to be reset as part of a resume procedure (whether because of a device quirk or because of the USB-Persist facility), thereby taking over a role formerly assigned to the post_reset method. As a consequence, post_reset no longer needs an argument indicating whether it is being called as part of a reset-resume. This separation of functions makes the code clearer. In addition, the pre_reset and post_reset method return types are changed; they now must return an error code. The return value is unused at present, but at some later time we may unbind drivers and re-probe if they encounter an error during reset handling. The existing pre_reset and post_reset methods in the usbhid, usb-storage, and hub drivers are updated to match the new requirements. For usbhid the post_reset routine is also used for reset_resume (duplicate method pointers); for the other drivers a new reset_resume routine is added. The change to hub.c looks bigger than it really is, because mark_children_for_reset_resume() gets moved down next to the new hub_reset_resume() routine. A minor change to usb-storage makes the usb_stor_report_bus_reset() routine acquire the host lock instead of requiring the caller to hold it already.

2007-07-12USB: remove excess code from hub.cAlan Stern
This patch (as917) removes a now-unnecessary level of subroutine nesting from hub.c. Since usb_port_suspend() does nothing but call hub_port_suspend(), and usb_port_resume() does nothing but call hub_port_resume(), there's no reason to keep the routines separate. Also included in the patch are a few cosmetic changes involving whitespace and use of braces. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-12USB: separate root and non-root suspend/resumeAlan Stern
This patch (as916) completes the separation of code paths for suspend and resume of root hubs as opposed to non-root devices. Root hubs will be power-managed through their bus_suspend and bus_resume methods, whereas normal devices will use usb_port_suspend() and usb_port_resume(). Changes to the hcd_bus_{suspend,resume} routines mostly represent motion of code that was already present elsewhere. They include: Adding debugging log messages, Setting the device state appropriately, and Adding a resume recovery time delay. Changes to the port-suspend and port-resume routines in hub.c include: Removal of checks for root devices (since they will never be triggered), and Removal of checks for NULL or invalid device pointers (these were left over from earlier kernel versions and aren't needed at all).

2007-07-12USB: prevent char device open/deregister raceAlan Stern
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.

This entails three changes: adding code to ehci-hcd to perform the handover, removing code from ohci-hcd to turn off ports during root-hub reinit, and adding code to ohci-hcd to turn on ports during PCI controller resume. (Other bus glue resume methods for platforms supporting high-speed controllers would need a similar change, if any existed.)

2007-07-12USB: make hub driver's release more robustAlan Stern
This revised patch (as893c) improves the method used by the hub driver to release its private data structure. The current code is non-robust, relying on a memory region not getting reused by another driver after it has been freed. The patch adds a reference count to the structure, resolving the question of when to release it.
