Use the port wait queue and make sure to check the serial disconnected flag before accessing private port data after waking up. This is is needed as the private port data (including the wait queue itself) can be gone when waking up after a disconnect. When switching to tty ports, some lifetime assumptions were changed. Specifically, close can now be called before the final tty reference is dropped as part of hangup at device disconnect. Even with the ftdi private-data refcounting this means that the port private data can be freed while a process is sleeping on modem-status changes and thus cannot be relied on to detect disconnects when woken up.

Unregister tty device in disconnect as is required by the USB stack. By deferring unregistration to when the last tty reference is dropped, the parent interface device can get unregistered before the child resulting in broken hotplug events being generated when the tty is finally closed: KERNEL[2290.798128] remove /devices/pci0000:00/0000:00:1d.7/usb2/2-1/2-1:3.1 (usb) KERNEL[2290.804589] remove /devices/pci0000:00/0000:00:1d.7/usb2/2-1 (usb) KERNEL[2294.554799] remove /2-1:3.1/tty/ttyACM0 (tty) The driver must deal with tty callbacks after disconnect by checking the disconnected flag.

2013-03-20USB: EHCI: fix regression in QH unlinkingAlan Stern1-1/+1
This patch (as1670) fixes a regression caused by commit 6402c796d3b4205d3d7296157956c5100a05d7d6 (USB: EHCI: work around silicon bug in Intel's EHCI controllers). The workaround goes through two IAA cycles for each QH being unlinked. During the first cycle, the QH is not added to the async_iaa list (because it isn't fully gone from the hardware yet), which means that list will be empty. Unfortunately, I forgot to update the IAA watchdog timer routine. It thinks that an empty async_iaa list means the timer expiration was an error, which isn't true any more. This problem didn't show up during initial testing because the controllers being tested all had working IAA interrupts. But not all controllers do, and when the watchdog timer expires, the empty-list check prevents the second IAA cycle from starting. As a result, URB unlinks never complete. The check needs to be removed. Among the symptoms of the regression are processes stuck in D wait states and hangs during system shutdown.

2013-03-20usb: gadget: f_rndis: Avoid to use ERROR macro if cdev can be nullTruls Bengtsson1-2/+1
The udc_irq service runs the isr_tr_complete_handler which in turn "nukes" the endpoints, including a call to rndis_response_complete, if appropriate. If the rndis_msg_parser fails here, an error will be printed using a dev_err call (through the ERROR() macro). However, if the usb cable was just disconnected the device (cdev) might not be available and will be null. Since the dev_err macro will dereference the cdev pointer we get a null pointer exception.

2013-03-20usb: gadget: udc-core: fix a regression during gadget driver unbindingAlan Stern1-1/+1
This patch (as1666) fixes a regression in the UDC core. The core takes care of unbinding gadget drivers, and it does the unbinding before telling the UDC driver to turn off the controller hardware. When the call to the udc_stop callback is made, the gadget no longer has a driver. The callback routine should not be invoked with a pointer to the old driver; doing so can cause problems (such as use-after-free accesses in net2280). This patch should be applied, with appropriate context changes, to all the stable kernels going back to 3.1.

2013-03-18USB: xhci - fix bit definitions for IMAN registerDmitry Torokhov1-2/+2
According to XHCI specification (5.5.2.1) the IP is bit 0 and IE is bit 1 of IMAN register. Previously their definitions were reversed. Even though there are no ill effects being observed from the swapped definitions (because IMAN_IP is RW1C and in legacy PCI case we come in with it already set to 1 so it was clearing itself even though we were setting IMAN_IE instead of IMAN_IP), we should still correct the values. This patch should be backported to kernels as old as 2.6.36, that contain the commit 4e833c0b87a30798e67f06120cecebef6ee9644c "xhci: don't re-enable IE constantly".

2013-03-18usb: musb: gadget: do *unmap_dma_buffer* only for valid DMA addrKishon Vijay Abraham I1-2/+7
musb does not use DMA buffer for ep0 but it uses the same giveback function *musb_g_giveback* for all endpoints (*musb_g_ep0_giveback* calls *musb_g_giveback*). So for ep0 case request.dma will be '0' and will result in kernel OOPS if tried to *unmap_dma_buffer* for requests in ep0. Fixed it by doing *unmap_dma_buffer* only for valid DMA addr and checking that musb_ep->dma is valid when unmapping.

2013-03-15USB: EHCI: fix regression during bus resumeAlan Stern3-1/+15
This patch (as1663) fixes a regression caused by commit 6e0c3339a6f19d748f16091d0a05adeb1e1f822b (USB: EHCI: unlink one async QH at a time). In order to avoid keeping multiple QHs in an unusable intermediate state, that commit changed unlink_empty_async() so that it unlinks only one empty QH at a time. However, when the EHCI root hub is suspended, _all_ async QHs need to be unlinked. ehci_bus_suspend() used to do this by calling unlink_empty_async(), but now this only unlinks one of the QHs, not all of them. The symptom is that when the root hub is resumed, USB communications don't work for some period of time. This is because ehci-hcd doesn't realize it needs to restart the async schedule; it assumes that because some QHs are already on the schedule, the schedule must be running. The easiest way to fix the problem is add a new function that unlinks all the async QHs when the root hub is suspended. This patch should be applied to all kernels that have the 6e0c3339a6f1 commit.

The commit 2e124b4a390ca85325fae75764bef92f0547fa25 removed the checks that prevented qt2_process_read_urb() from trying to put chars into ttys that weren't actually opened. This resulted in 'tty is NULL' warnings from flush_to_ldisc() when the device was used. The devices use just one read urb for all ports. As a result qt2_process_read_urb() may be called with the current port set to a port number that has not been opened. Add a check if the port is open before calling tty_flip_buffer_push().

This patch adds support for the Lake Shore Cryotronics devices to the CP210x driver.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v3.9-rc3 Most fixes are on 'musb' driver. There's a sparse warning fix which marks omap2430_glue as static, a build warning fix which was found with randconfig, a fix for omap_musb_mailbox check and removal of 'select' from musb's Kconfig to prevent Kconfig warnings. Other than that, pxa25x got a fix which was introduced by the latest conversion to udc_start/udc_stop patchset, kernel-doc warnings for composite layer and dwc3 got a build fix on sparc64.

2013-03-11usb: gadget: pxa25x: fix disconnect reportingFelipe Balbi1-0/+4
when commit 6166c24 (usb: gadget: pxa25x_udc: convert to udc_start/udc_stop) converted this driver to udc_start/udc_stop, it failed to consider the fact that stop_activity() is called from disconnect interrupt. Fix the problem so that gadget drivers know about proper disconnect sequences. Signed-off-by: Felipe Balbi <balbi@ti.com>

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull namespace bugfixes from Eric Biederman: "This is three simple fixes against 3.9-rc1. I have tested each of these fixes and verified they work correctly. The userns oops in key_change_session_keyring and the BUG_ON triggered by proc_ns_follow_link were found by Dave Jones. I am including the enhancement for mount to only trigger requests of filesystem modules here instead of delaying this for the 3.10 merge window because it is both trivial and the kind of change that tends to bit-rot if left untouched for two months." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: proc: Use nd_jump_link in proc_ns_follow_link fs: Limit sys_mount to only request filesystem modules (Part 2). fs: Limit sys_mount to only request filesystem modules. userns: Stop oopsing in key_change_session_keyring
