Queueing to receive an ISO packet with a payload length of zero silently does nothing in dualbuffer mode, and crashes the kernel in packet-per-buffer mode. Return an error in dualbuffer mode, because the DMA controller won't let us do what we want, and work correctly in packet-per-buffer mode.

Make the USB core check the bandwidth when switching from one interface alternate setting to another. Also check the bandwidth when resetting a configuration (so that alt setting 0 is used). If this check fails, the device's state is unchanged. If the device refuses the new alt setting, re-instate the old alt setting in the host controller hardware. If a USB device doesn't have an alternate interface setting 0, install the first alt setting in its descriptors when a new configuration is requested, or the device is reset. Add a mutex per root hub to protect bandwidth operations: adding/reseting/changing configurations, and changing alternate interface settings. We want to ensure that the xHCI host controller and the USB device are set up for the same configurations and alternate settings. There are two (possibly three) steps to do this: 1. The host controller needs to check that bandwidth is available for a different setting, by issuing and waiting for a configure endpoint command. 2. Once that returns successfully, a control message is sent to the device. 3. If that fails, the host controller must be notified through another configure endpoint command. The mutex is used to make these three operations seem atomic, to prevent another driver from using more bandwidth for a different device while we're in the middle of these operations. While we're touching the bandwidth code, rename usb_hcd_check_bandwidth() to usb_hcd_alloc_bandwidth(). This function does more than just check that the bandwidth change won't exceed the bus bandwidth; it actually changes the bandwidth configuration in the xHCI host controller.

Refactor out the code to find alternate interface settings into usb_find_alt_setting(). Print a debugging message and return null if the alt setting is not found. While we're at it, correct a bug in the refactored code. The interfaces in the configuration's interface cache are not necessarily in numerical order, so we can't just use the interface number as an array index. Loop through the interface caches, looking for the correct interface. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The xHCI driver issues a Configure Endpoint command for two reasons: - a new configuration or alternate interface setting is selected - a quirky Fresco Logic prototype requires the command after a Reset Endpoint command. The xHCI driver only waits on the command in the first case. When a configure endpoint command completes, the driver needs to know why the command was generated. When the driver only supported selecting an initial configuration, the check was simple. Unfortunately that check doesn't work now that the driver supports alternate interfaces. If an endpoint must be dropped (because it's not in the new alternate setting) and no new endpoints are added, the math involving xhci_last_valid_endpoint() will assign -1 to an unsigned integer and cause an out-of-bounds array access. Move the check for the quirky hardware sooner and avoid the bad array access. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

When a driver wants to switch to a different alternate setting for an interface, the USB core will (soon) check whether there is enough bandwidth. Once the new alternate setting is installed in the xHCI hardware, the USB core will send a USB_REQ_SET_INTERFACE control message. That can fail in various ways, and the USB core needs to be able to reinstate the old alternate setting. With the old code, reinstating the old alt setting could fail if the there's not enough memory to allocate new endpoint rings. Keep around a cache of (at most 31) endpoint rings for this case. When we successfully switch the xHCI hardware to the new alt setting, the old alt setting's rings will be stored in the cache. Therefore we'll always have enough rings to satisfy a conversion back to a previous device setting.

Make the USB Test & Measurement driver use usb_clear_halt() instead of usb_control_msg() to clear a stalled endpoint. This will allow devices to be tested under an xHCI host controller. The endpoint stall will not be cleared in the internal xHCI hardware state unless usb_clear_halt() is used.

This patch (as1312) fixes a minor bug in usb-storage. The fill_inquiry() routine neglects to pre-load the inquiry data buffer with spaces. As a result, if the vendor name is shorter than 8 characters or the product name is shorter than 16, the remainder will be filled with garbage. The patch also removes some unnecessary calls to strlen(). Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch (as1311) fixes a problem in usb-storage: Some devices are pretty broken when it comes to reporting sense data. The information they send back indicates that they have more than 18 bytes of sense data available, but when the system asks for more than 18 they fail or hang. The symptom is that probing fails with multiple resets. The patch adds a new BAD_SENSE flag to indicate that usb-storage should never ask for more than 18 bytes of sense data. The flag can be set in an unusual_devs entry or via the "quirks=" module parameter, and it is set automatically whenever a REQUEST SENSE command for more than 18 bytes fails or times out. An unusual_devs entry is added for the Agfa photo frame, which uses a Prolific chip having this bug.

This patch (as1303) revises the USB Power Management infrastructure to make it compatible with the new driver-model Runtime PM framework: Drivers are no longer allowed to access intf->pm_usage_cnt directly; the PM framework manages its own usage counters. usb_autopm_set_interface() is eliminated, because it directly sets intf->pm_usage_cnt. usb_autopm_enable() and usb_autopm_disable() are eliminated, because they call usb_autopm_set_interface(). usb_autopm_get_interface_no_resume() and usb_autopm_put_interface_no_suspend() are added. They correspond to pm_runtime_get_noresume() and pm_runtime_put_noidle() in the PM framework. The power/level attribute no longer accepts "suspend", only "on" and "auto". The PM framework doesn't allow devices to be forced into a suspended mode. The hub driver contains the only code that violates the new guidelines. It is updated to use the new interface routines instead. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Enable USB charging, only after all regulators are enabled. Its observed that enabling USB charging before regulators are enabled, causes USB charging to fail.
