In USB20 specification, describes in chapter 9.4.5: The Remote Wakeup field can be modified by the SetFeature() and ClearFeature() requests using the DEVICE_REMOTE_WAKEUP feature selector. In USB30 specification, also describes in chapter 9.4.5: The Function Remote Wakeup field can be modified by the SetFeature() requests using the FUNCTION_SUSPEND feature selector. In chapter 9.4.9 Set Feature reference, it describes Function Remote Wake Enabled/Disabled at suspend options by SET_FEATURE. In USB30 specification only mentioned SetFeature(), so we need use SET_FEATURE replace CLEAR_FEATURE to disable USB30 function remote wakeup in suspend options. Signed-off-by:

This commit adds a new trigger responsible for turning on LED when USB device gets connected to the selected USB port. This can can useful for various home routers that have USB port(s) and a proper LED telling user a device is connected. The trigger gets its documentation file but basically it just requires enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1). There was a long discussion on design of this driver. Its current state is a result of picking them most adjustable solution as others couldn't handle all cases. 1) It wasn't possible for the driver to register separated trigger for each USB port. Some physical USB ports are handled by more than one controller and so by more than one USB port. E.g. USB 2.0 physical port may be handled by OHCI's port and EHCI's port. It's also not possible to assign more than 1 trigger to a single LED and implementing such feature would be tricky due to syncing triggers and sysfs conflicts with old triggers. 2) Another idea was to register trigger per USB hub. This wouldn't allow handling devices with multiple USB LEDs and controllers (hubs) controlling more than 1 physical port. It's common for hubs to have few ports and each may have its own LED. This final trigger is highly flexible. It allows selecting any USB ports for any LED. It was also modified (comparing to the initial version) to allow choosing ports rather than having user /guess/ proper names. It was successfully tested on SmartRG SR400ac which has 3 USB LEDs, 2 physical ports and 3 controllers. It was noted USB subsystem already has usb-gadget and usb-host triggers but they are pretty trivial ones. They indicate activity only and can't have ports specified. In future it may be good idea to consider adding activity support to usbport as well. This should allow switching to this more generic driver and maybe marking old ones as obsolete. This can be implemented with another sysfs file for setting mode. The default mode wouldn't change so there won't be ABI breakage and so such feature can be safely implemented later. There was also an idea of supporting other devices (PCI, SDIO, etc.) but as this driver already contains some USB specific code (and will get more) these should be probably separated drivers (triggers).

With the session bit based PM runtime working on musb, we've implemented few quirks to attempt to detect the current state of the hardware. One of the quirks is for invalid VBUS as peripheral, but it is not working in all cases. If we start musb on dm3730 as a peripheral with no cable connected, we will get the devctl 91 state once and will never idle as there are not further interrupts from musb. So we need to ignore the first devctl 91 state as there will be more interrupts if we're connected. The invalid VBUS state also can happen always when connected to certain USB hubs. Looks like musb on dm3730 can claim invalid VBUS with some hubs while 3717-evm and BeagleBone don't. This causes session as peripheral to fail for dm3730 with some hubs. This too is fixed by ignoring only the first invalid VBUS. When connected, we can just look at the session bit as that will clear automatically when the session ends.

If we unconfigure musb as a USB peripheral with cable connected, and then remove the cable, no interrupts will happen. And musb thinks we're still connected keeping the device active. Now with the session bit based PM runtime working for musb, we can fix this issue by calling musb irq_work. That rechecks the devctl register and reconfigures PM runtime based on the devctl.

This patch fixes a NULL pointer dereference caused by a race codition in the probe function of the legousbtower driver. It re-structures the probe function to only register the interface after successfully reading the board's firmware ID. The probe function does not deregister the usb interface after an error receiving the devices firmware ID. The device file registered (/dev/usb/legousbtower%d) may be read/written globally before the probe function returns. When tower_delete is called in the probe function (after an r/w has been initiated), core dev structures are deleted while the file operation functions are still running. If the 0 address is mappable on the machine, this vulnerability can be used to create a Local Priviege Escalation exploit via a write-what-where condition by remapping dev->interrupt_out_buffer in tower_write. A forged USB device and local program execution would be required for LPE. The USB device would have to delay the control message in tower_probe and accept the control urb in tower_open whilst guest code initiated a write to the device file as tower_delete is called from the error in tower_probe. This bug has existed since 2003. Patch tested by emulated device. Reported-by:

Pull ARM fixes from Russell King: "Most of this update are fixes primarily discovered from testing on the older StrongARM 1110 and PXA systems, as a result of recent interest from several people in these platforms: - Locomo interrupt handling incorrectly stores the handler data in the chip's private data slot: when Locomo is combined with an interrupt controller who's chip uses the chip private data, this leads to an oops. - SA1111 was missing a call to clk_disable() to clean up after a failed probe. - SA1111 and PCMCIA suspend/resume was broken: The PCMCIA "ds" layer was using the legacy bus suspend/resume methods, which the core PM code is no longer calling as a result of device_pm_check_callbacks() introduced in commit aa8e54b5 ("PM / sleep: Go direct_complete if driver has no callbacks"). SA1111 was broken due to changes to PCMCIA which makes PCMCIA suspend itself later than the SA1111 code expects, and resume before the SA1111 code has initialised access to the pcmcia sub-device. - the default SA1111 interrupt mask polarity got messed up when it was converted to use a dynamic interrupt base number for its interrupts. - fix platform_get_irq() error code propagation, which was causing problems on platforms where the interrupt may not be available at probe time in DT setups. - fix the lack of clock to PCMCIA code on PXA platforms, which was omitted in conversions of PXA to CCF. - fix an oops in the PXA PCMCIA code caused by a previous commit not realising that Lubbock is different from the rest of the PXA PCMCIA drivers. - ensure that SA1111 low-level PCMCIA drivers propagate their error codes to the main probe function, rather than the driver silently accepting a failure. - fix the sa11xx debugfs reporting of timing information, which always indicated zero due to the clock being a factor of 1000 out. - fix the polarity of the status change signal reported from the sockets.

When handling ack for atomic opcodes like "fetch&add" or "cmp&swp", the method send_atomic_ack() saves the ack before sending it, in case it gets lost and never reach the requester. In which case the method duplicate_request() will need to find it using the duplicated request.psn. But send_atomic_ack() used a wrong psn value and thus the above ack was never found. This fix uses the ack.psn to locate the ack in case its needed. This fix also copies the ack packet to the skb's control buffer since duplicate_request() will need it when calling rxe_xmit_packet() Fixes: 8700e3e7 ("Soft RoCE driver") Signed-off-by:
