2008-05-14USB: create attributes before sending ueventAlan Stern
This patch (as1087d) fixes a long-standing problem in usbcore: Device, interface, and endpoint attributes aren't added until _after_ the creation uevent has already been broadcast. Unfortunately there are a few attributes which cannot be created that early. The "descriptors" attribute is binary and so must be created separately. The power-management attributes can't be created until the dev/power/ group exists. And the interface string can vary from one altsetting to another, so it has to be created dynamically.

2008-04-24USB: rework sysfs removal of interface filesAlan Stern
Removing an interface's sysfs files before unregistering the interface doesn't work properly, because usb_unbind_interface() will reinstall altsetting 0 and thereby create new sysfs files. This patch (as1074) removes the files after the unregistration is finished. It's not quite as clean, but at least it works. Also, there's no need to check if an interface has been registered before removing its sysfs files. If it hasn't been registered then the files won't have been created, so usb_remove_sysfs_intf_files() will simply do nothing.

2008-04-24USB: check serial-number string after device resetAlan Stern
This patch (as1048) extends the descriptor checking after a device is reset. Now the SerialNumber string descriptor is compared to its old value, in addition to the device and configuration descriptors. As a consequence, the kmalloc() call in usb_string() is now on the error-handling pathway for usb-storage. Hence its allocation type is changed to GFO_NOIO.

2008-02-01USB: mark USB drivers as being GPL onlyGreg Kroah-Hartman
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.

2007-11-28USB: uevent environment key fixAlan Stern
This patch (as1010) was written by both Kay Sievers and me. It solves the problem of duplicated keys in USB uevent structures by refactoring the uevent subroutines, taking advantage of the way the hotplug core calls uevent handlers for the device's bus and for the device's type. Keys needed for both USB-device and USB-interface events are added in usb_uevent(), which is the bus handler. Keys appropriate only for USB-device or USB-interface events are added in usb_dev_uevent() or usb_if_uevent() respectively, the type handlers. In addition, unnecessary tests for NULL pointers are removed as are duplicated debugging log statements.

2007-11-28USB: keep track of whether interface sysfs files existAlan Stern
This patch (as1009) solves the problem of multiple registrations for USB sysfs files in a more satisfying way than the existing code.

2007-10-25USB: fix interface sysfs file-creation bugAlan Stern
This patch (as1005) fixes a rather subtle problem. When usb_set_configuration() registers the interfaces and their files in sysfs, it doesn't expect those files to exist already. But when an interface is registered, its driver may call usb_set_interface() and thereby cause the sysfs files to be created. The result is an error when usb_set_configuration() goes on to create those same files again. The (not-so-great) solution is to have usb_set_configuration() remove any existing files before creating them.

This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke.

2007-10-12USB: break apart flush_endpoint and disable_endpointAlan Stern
This patch (as988) breaks usb_hcd_endpoint_disable() apart into two routines. The first, usb_hcd_flush_endpoint() does the -ESHUTDOWN unlinking of all URBs in the endpoint's queue and waits for them to complete. The second, usb_hcd_disable_endpoint() -- renamed for better grammatical style -- merely calls the HCD's endpoint_disable method. The changeover is easy because the routine currently has only one caller. This separation of function will be exploited in the following patch: When a device is suspended, the core will be able to cancel all outstanding URBs for that device while leaving the HCD's endpoint-related data structures intact for later. As an added benefit, HCDs no longer need to check for existing URBs in their endpoint_disable methods. It is now guaranteed that there will be none.

2007-10-12USB: don't touch sysfs stuff when altsetting is unchangedAlan Stern
This patch (as955) prevents the interface-related sysfs files and endpoint pseudo-devices from being deleted and recreated when a call to usb_set_interface() specifies the current altsetting. Since the altsetting doesn't get changed, there's no need to do anything. Furthermore, avoiding changes to the endpoint devices will be necessary in the future. This code is called from usb_reset_device(), which gets invoked for reset-resume processing, but upcoming changes to the PM and driver cores will make it impossible to register devices while a suspend/resume transition is in progress. Since we don't need to re-register those endpoint devices anyhow, it's best to skip the whole thing.

2007-10-12USB: avoid using urb->pipe in usbcoreAlan Stern
This patch (as946) eliminates many of the uses of urb->pipe in usbcore. Unfortunately there will have to be a significant API change, affecting all USB drivers, before we can remove it entirely. This patch contents itself with changing only the interface to usb_buffer_map_sg() and friends: The pipe argument is replaced with a direction flag. That can be done easily because those routines get used in only one place. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-12USB: add ep->enableAlan Stern
This patch (as944) adds an explicit "enabled" field to the usb_host_endpoint structure and uses it in place of the current mechanism. This is merely a time-space tradeoff; it makes checking whether URBs may be submitted to an endpoint simpler. The existing mechanism is efficient when converting urb->pipe to an endpoint pointer, but it's not so efficient when urb->ep is used instead. As a side effect, the procedure for enabling an endpoint is now a little more complicated. The ad-hoc inline code in usb.c and hub.c for enabling ep0 is now replaced with calls to usb_enable_endpoint, which is no longer static.

2007-04-27USB: make usbdevices export their device nodes instead of using a separate classKay Sievers
o The "real" usb-devices export now a device node which can populate /dev/bus/usb. o The usb_device class is optional now and can be disabled in the kernel config. Major/minor of the "real" devices and class devices are the same. o The environment of the usb-device event contains DEVNUM and BUSNUM to help udev and get rid of the ugly udev rule we need for the class devices. o The usb-devices and usb-interfaces share the same bus, so I used the new "struct device_type" to let these devices identify themselves. This also removes the current logic of using a magic platform-pointer. The name of the device_type is also added to the environment which makes it easier to distinguish the different kinds of devices on the same subsystem.

2007-04-27USB: remove use of the bus rwsem, as it doesn't really protect anything.Greg Kroah-Hartman
The driver core stopped using the rwsem a long time ago, yet the USB core still grabbed the lock, thinking it protected something. This patch removes that useless use.

2007-03-09USB: set the correct interval for interrupt URBsAlan Stern
This patch (as862) fixes a couple of bugs in the way usbcore handles intervals for interrupt URBs. usb_interrupt_msg (and usb_bulk_msg for backward compatibility) don't set the interval correctly for high-speed devices. proc_do_submiturb() doesn't set it correctly when a bulk URB is submitted to an interrupt endpoint.

2007-02-23USB: add a blacklist for devices that can't handle some things we throw at them.Oliver Neukum
This adds a blacklist to the USB core to handle some autosuspend and string issues that devices have. Originally written by Oliver, but hacked up a lot by Greg. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-02-16USB: unconfigure devices which have config 0Alan Stern
Some USB devices do have a configuration 0, in contravention of the USB spec. Normally 0 is supposed to indicate that a device is unconfigured. While we can't change what the device is doing, we can change usbcore. This patch (as852) allows usb_set_configuration() to accept a config value of -1 as indicating that the device should be unconfigured. The request actually sent to the device will still contain 0 as the value. But even if the device does have a configuration 0, dev->actconfig will be set to NULL and dev->state will be set to USB_STATE_ADDRESS. Without some sort of special-case handling like this, there is no way to unconfigure these non-compliant devices.

2006-12-01usbcore: remove unused argument in autosuspendAlan Stern
Thanks to several earlier patches, usb_autosuspend_device() and usb_autoresume_device() are never called with a second argument other than 1. This patch (as819) removes the now-redundant argument. It also consolidates some common code between those two routines, putting it into a new subroutine called usb_autopm_do_device(). And it includes a sizable kerneldoc update for the affected functions. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
