2011-02-17xhci: Use GFP_NOIO during device reset.Sarah Sharp
commit a6d940dd759bf240d28624198660ed34582a327b upstream. When xhci_discover_or_reset_device() is called after a host controller power loss, the virtual device may need to be reallocated. Make sure xhci_alloc_dev() uses GFP_NOIO. This avoid causing a deadlock by allowing the kernel to flush pending I/O while reallocating memory for a virtual device for a USB mass storage device that's holding the backing store for dirty memory buffers. This patch should be queued for the 2.6.37 stable tree. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-02-17usb: Realloc xHCI structures after a hub is verified.Sarah Sharp
commit 653a39d1f61bdc9f277766736d21d2e9be0391cb upstream. When there's an xHCI host power loss after a suspend from memory, the USB core attempts to reset and verify the USB devices that are attached to the system. The xHCI driver has to reallocate those devices, since the hardware lost all knowledge of them during the power loss. When a hub is plugged in, and the host loses power, the xHCI hardware structures are not updated to say the device is a hub. This is usually done in hub_configure() when the USB hub is detected. That function is skipped during a reset and verify by the USB core, since the core restores the old configuration and alternate settings, and the hub driver has no idea this happened. This bug makes the xHCI host controller reject the enumeration of low speed devices under the resumed hub. Therefore, make the USB core re-setup the internal xHCI hub device information by calling update_hub_device() when hub_activate() is called for a hub reset resume. After a host power loss, all devices under the roothub get a reset-resume or a disconnect. This patch should be queued for the 2.6.37 stable tree.

commit 96a3e79edff6f41b0f115a82f1a39d66218077a7 upstream. Added 0x0307 device id to support Motorola cables to the pl2303 usb serial driver. This cable has a modified chip that is a pl2303, but declares itself as 0307.

2011-02-17USB: fix race between root-hub resume and wakeup requestsAlan Stern
commit bf3d7d40e42a85ca73a34e1385ff34f092a384eb upstream. The USB core keeps track of pending resume requests for root hubs, in order to resolve races between wakeup requests and suspends. However the code that does this is subject to another race (between wakeup requests and resumes) because the WAKEUP_PENDING flag is cleared before the resume occurs, leaving a window in which another wakeup request might arrive. This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING flag after the resume instead of before it. This fixes Bugzilla #24952.

commit d199c96d41d80a567493e12b8e96ea056a1350c1 upstream. If anyone comes across a high-speed hub that (by mistake or by design) claims to have no Transaction Translators, plugging a full- or low-speed device into it will cause the USB stack to crash. This patch (as1446) prevents the problem by ignoring such devices, since the kernel has no way to communicate with them.

This patch (as1442) fixes a bug in g_printer: Module parameters should not be marked "__initdata" if they are accessible in sysfs (i.e., if the mode value in the module_param() macro is nonzero). Otherwise attempts to access the parameters will cause addressing violations. Character-string module parameters must not be marked "__initdata" if the module can be unloaded, because the kernel needs to access the parameter variable at unload time in order to free the dynamically-allocated string.

2011-02-17USB: EHCI: fix DMA deallocation bugAlan Stern
commit f75593ceaa08e6d27aec1a5de31cded19e850dd1 upstream. This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is used to compute the size in a dma_alloc_coherent() call, but then it gets changed later on. As a result, the corresponding call to dma_free_coherent() passes a different size from the original allocation. Fix the problem by adjusting ehci->periodic_size before carrying out any of the memory allocations.

2011-02-17USB serial: add missing .usb_driver field in serial driversAlan Stern
commit 5620b5f7f19e9ee3fcf6ecf493fed7821b7b495b upstream. This patch (as1443) fixes a bug found in many of the USB serial drivers: They don't set the .usb_driver field in their usb_serial_driver structure. This field is needed for assigning dynamic IDs for device matching. In addition, starting with the 2.6.37 kernel, the .usb_driver field is needed for proper autosuspend operation. Without it, attempts to open the device file will fail.

commit d14fc1a74e846d7851f24fc9519fe87dc12a1231 upstream. Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

2011-02-17USB: EHCI: ASPM quirk of ISOC on AMD SB800Alex He
commit 05570297ecbe834b1756b522412b68eaffb9ab11 upstream. When ASPM PM Feature is enabled on UMI link, devices that use ISOC stream of data transfer may be exposed to longer latency causing less than optimal per- formance of the device. The longer latencies are normal and are due to link wake time coming out of low power state which happens frequently to save power when the link is not active. The following code will make exception for certain features of ASPM to be by passed and keep the logic normal state only when the ISOC device is connected and active. This change will allow the device to run at optimal performance yet minimize the impact on overall power savings.

2011-01-07xhci: Fix issue with port array setup and buggy hosts.Sarah Sharp
commit f8bbeabc34aa945ab4275abc9a4dfde0aea798ca upstream. Fix two bugs with the port array setup. The first bug will only show up with broken xHCI hosts with Extended Capabilities registers that have duplicate port speed entries for the same port. The idea with the original code was to set the port_array entry to -1 if the duplicate port speed entry said the port was a different speed than the original port speed entry. That would mean that later, the port would not be exposed to the USB core. Unfortunately, I forgot a continue statement, and the port_array entry would just be overwritten in the next line. The second bug would happen if there are conflicting port speed registers (so that some entry in port_array is -1), or one of the hardware port registers was not described in the port speed registers (so that some entry in port_array is 0). The code that sets up the usb2_ports array would accidentally claim those ports. That wouldn't really cause any user-visible issues, but it is a bug. This patch should go into the stable trees that have the port array and USB 3.0 port disabling prevention patches.

commit 02e2c51ba3e80acde600721ea784c3ef84da5ea1 upstream. This patch (as1435) fixes an obscure and unlikely race in ehci-hcd. When an async URB is unlinked, the corresponding QH is removed from the async list. If the QH's endpoint is then disabled while the URB is being given back, ehci_endpoint_disable() won't find the QH on the async list, causing it to believe that the QH has been lost. This will lead to a memory leak at best and quite possibly to an oops. The solution is to trust usbcore not to lose track of endpoints. If the QH isn't on the async list then it doesn't need to be taken off the list, but the driver should still wait for the QH to become IDLE before disabling it. In theory this fixes Bugzilla #20182. In fact the race is so rare that it's not possible to tell whether the bug is still present. However, adding delays and making other changes to force the race seems to show that the patch works.
