2008-07-06Revert "USB: don't explicitly reenable root-hub status interrupts"Linus Torvalds
This reverts commit e872154921a6b5256a3c412dd69158ac0b135176. Andrey Borzenkov reports that it resulted in a totally hung machine for him when loading the OHCI driver. Extensive netconsole capture with SysRq output shows that modprobe gets stuck in ohci_hub_status_data() when probing and enabling the OHCI controller, see for example http://lkml.org/lkml/2008/7/5/236 for an analysis. The problem appears to be an interrupt flood triggered by the commit that gets reverted, and Andrey confirmed that the revert makes things work for him again.

2008-07-03USB: don't lose disconnections during suspendAlan Stern
This patch (as1111) fixes a bug in the hub driver. When a hub resumes, disconnections that occurred while the hub was suspended are lost. A completely different fix for this problem has already been accepted for 2.6.27; however the problem still needs to be handled in 2.6.26.

2008-07-03USB: fix interrupt disabling for HCDs with shared interrupt handlersStefan Becker
USB: fix interrupt disabling for HCDs with shared interrupt handlers As has been discussed several times on LKML, IRQF_SHARED | IRQF_DISABLED doesn't work reliably, i.e. a shared interrupt handler CAN'T be certain to be called with interrupts disabled. Most USB HCD handlers use IRQF_DISABLED and therefore havoc can break out if they share their interrupt with a handler that doesn't use it. On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED) was registered before ehci_hcd and one uhci_hcd instance. Therefore all usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance happened with interrupts enabled. That led to random lockups as USB core HCD functions that acquire the same spinlock could be called twice from interrupt handlers. This patch updates usb_hcd_irq() to always disable/restore interrupts. usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.

2008-07-03USB: ohci - record data toggle after unlinkDavid Brownell
This patch fixes a problem with OHCI where canceling bulk or interrupt URBs may lose track of the right data toggle. This seems to be a longstanding bug, possibly dating back to the Linux 2.4 kernel, which stayed hidden because (a) about half the time the data toggle bit was correct; (b) canceling such URBs is unusual; and (c) the few drivers which cancel these URBs either [1] do it only as part of shutting down, or [2] have fault recovery logic, which recovers. For those transfer types, the toggle is normally written back into the ED when each TD is retired. But canceling bypasses the mechanism used to retire TDs ... so on average, half the time the toggle bit will be invalid after cancelation. The fix is simple: the toggle state of any canceled TDs are propagated back to the ED in the finish_unlinks function. (Issue found by leonidv11@gmail.com ...)

2008-07-03USB: ehci - fix timer regressionDavid Brownell
This patch fixes a regression in the EHCI driver's TIMER_IO_WATCHDOG behavior. The patch "USB: EHCI: add separate IAA watchdog timer" changed how that timer is handled, so that short timeouts on the remaining timer (unfortunately, overloaded) would never be used. This takes a more direct approach, reorganizing the code slightly to be explicit about only the I/O watchdog role now being overridable. It also replaces a now-obsolete comment describing older timer behavior.

2008-05-29USB: EHCI: fix performance regressionAlan Stern
This patch (as1099) fixes a performance regression in ehci-hcd. The fundamental problem is that queue headers get removed from the schedule too quickly, since the code checks for a counter advancing rather than making an actual time-based check. The latency involved in removing the queue header and then relinking it can severely degrade certain kinds of workloads. The patch replaces a simple counter with a timestamp derived from the controller's uframe value. In addition, the delay for unlinking an idle queue header is increased from 5 ms to 10 ms; since some controllers (nVidia) have a latency of up to 1 ms for unlinking, this reduces the relative impact from 20% to 10%. Finally, a logical error left over from the IAA watchdog-timer conversion is corrected. Now the driver will always either unlink an idle queue header or set up a timer to unlink it later. The old code would sometimes fail to do either.

2008-05-29USB: EHCI: fix bug in Iso schedulingAlan Stern
This patch (as1098) changes the way ehci-hcd schedules its periodic Iso transfers. That the current scheduling code is wrong is clear on the face of it: Sometimes it returns -EL2NSYNC (meaning that an URB couldn't be scheduled because it was submitted too late), but it does this even when the URB_ISO_ASAP flag is set (meaning the URB should be scheduled as soon as possible). The new code properly implements as-soon-as-possible scheduling, assigning the next unexpired slot as the URB's starting point. It also is more careful about checking for Iso URB completion: It doesn't bother to check for activity during frames that are already over, and it allows for the possibility that some of the URB's packets may have raced the hardware when they were submitted and so never got used (the packet status is set to -EXDEV). This fixes problems several people have experienced with USB video applications.

This patch (as1095) cleans up the HCD glue and several of the EHCI bus-glue files. The ehci->is_tdi_rh_tt flag is redundant, since it means the same thing as the hcd->has_tt flag, so it is removed and the other flag used in its place. Some of the bus-glue files didn't get the relinquish_port method added to their hc_driver structures. Although that routine currently doesn't do anything for controllers with an integrated TT, in the future it might. So the patch adds it where it is missing. Lastly, some of the bus-glue files have erroneous entries for their hc_driver's suspend and resume methods. These method pointers are specific to PCI and shouldn't be used otherwise.

This patch (as1094) changes the output of the "descriptors" binary attribute. Now it will contain the device descriptor followed by all the configuration descriptors, not just the descriptor for the current config. Userspace libraries want to have access to the kernel's cached descriptor information, so they can learn about device characteristics without having to wake up suspended devices. So far the only user of this attribute is the new libusb-1.0 library; thus changing its contents shouldn't cause any problems. This should be considered for 2.6.26, if for no other reason than to minimize the range of releases in which the attribute contains only the current config descriptor. Also, it doesn't hurt that the patch removes the device locking -- which was formerly needed in order to know for certain which config was indeed current.

2008-05-29USB: fix possible deadlock involving sysfs attributesAlan Stern
There is a potential deadlock when the usb_generic driver is unbound from a device. The problem is that generic_disconnect() is called with the device lock held, and it removes a bunch of device attributes from sysfs. If a user task happens to be running an attribute method at the time, the removal will block until the method returns. But at least one of the attribute methods (the store routine for power/level) needs to acquire the device lock! This patch (as1093) eliminates the deadlock by moving the calls to create and remove the sysfs attributes from the usb_generic driver into usb_new_device() and usb_disconnect(), where they can be invoked without holding the device lock. Besides, the other sysfs attributes are created when the device is registered and removed when the device is unregistered. So it seems only fitting for the extra attributes to be created and removed at the same time. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-05-29USB: Firmware loader driver for USB Apple iSight cameraMatthew Garrett
Uninitialised Apple iSight drivers present with a distinctive USB ID. Once firmware has been uploaded, they disconnect and reconnect with a new ID. At this point they can be driven by the uvcvideo driver. As this is unique to the Apple cameras and not functionality shared by any other UVC devices, it makes sense to provide the firmware loading functionality in a separate driver. This driver will read an isight.fw file extracted from the Apple driver using the tools at http://bersace03.free.fr/ift/ and upload it to the camera. It will also handle the case where the device loses its firmware during hibernation and must have it reloaded.

2008-05-20USB: ehci-orion: the Orion EHCI root hub does have a Transaction TranslatorLennert Buytenhek
Commit 7329e211b987a493cbcfca0e98c60eb108ab42df ("USB: root hubs don't lie about their number of TTs") requires the various platform EHCI glue modules to set ->has_tt if the root hub has a Transaction Translator. The Orion EHCI root hub does have a Transaction Translator, so set ->has_tt in ehci_orion_setup(). This fixes oopsing on plugging in a low speed device.

2008-05-20USB: serial: ch341: New VID/PID for CH341 USB-serialMichael F. Robbins
Recent USB-serial devices using the WinChipHead CH340/CH341 chipset are being shipped with a new vendor/product ID code pair, but an otherwise identical device. (This is confirmed by looking at INF for the included Windows driver.) Patch is tested and working, both with new and old devices. Signed-off-by: Michael F.

2008-05-20USB: add TELIT HDSPA UC864-E modem to option driverGreg Kroah-Hartman
This adds the Telit UC864-E HDSPA modem support to the option driver. This lets their customers comply with the GPL instead of having to use a binary driver from the manufacturer.

2008-05-20USB: Core: fix race in device_createGreg Kroah-Hartman
There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata(). Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
