2012-01-12USB: isight: fix kernel bug when loading firmwareGreg Kroah-Hartman
commit 59bf5cf94f0fa3b08fb1258b52649077b7d0914d upstream. We were sending data on the stack when uploading firmware, which causes some machines fits, and is not allowed. Fix this by using the buffer we already had around for this very purpose. Reported-by: Wouter M. Koolen <wmkoolen@cwi.nl> Tested-by: Wouter M.

2012-01-12drivers/usb/class/cdc-acm.c: clear dangling pointerJulia Lawall
commit e7c8e8605d0bafc705ff27f9da98a1668427cc0f upstream. On some failures, the country_code field of an acm structure is freed without freeing the acm structure itself. Elsewhere, operations including memcpy and kfree are performed on the country_code field. The patch sets the country_code field to NULL when it is freed, and likewise sets the country_code_size field to 0.

2011-12-21USB: option: Removing one bogus and adding some new Huawei combinationsBjørn Mork
commit 02a551c9755b799579e0a093bcc99b80b4dc1453 upstream. Huawei use the product code HUAWEI_PRODUCT_E353 (0x1506) for a number of different devices, which each can appear with a number of different descriptor sets. Different types of interfaces can be identified by looking at the subclass and protocol fields Subclass 1 protocol 8 is actually the data interface of a CDC ECM set, with subclass 1 protocol 9 as the control interface. Neither support serial data communcation, and cannot therefore be supported by this driver. At the same time, add a few other sets which appear if the device is configured in "Windows mode" using this modeswitch message: 55534243000000000000000000000011060000000100000000000000000000 Signed-off-by: Bjørn Mork <bjorn@mork.no> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-12-09xHCI: fix bug in xhci_clear_command_ring()Andiry Xu
commit 158886cd2cf4599e04f9b7e10cb767f5f39b14f1 upstream. When system enters suspend, xHCI driver clears command ring by writing zero to all the TRBs. However, this also writes zero to the Link TRB, and the ring is mangled. This may cause driver accesses wrong memory address and the result is unpredicted. When clear the command ring, keep the last Link TRB intact, only clear its cycle bit. This should fix the "command ring full" issue reported by Oliver Neukum. This should be backported to stable kernels as old as 2.6.37, since the commit 89821320 "xhci: Fix command ring replay after resume" is merged.

commit 811c926c538f7e8d3c08b630dd5844efd7e000f6 upstream. The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. The IN iso stream can only start on the first uframe (0-2 for a 165 us) because of CSPLIT transactions. For the OUT iso stream there no such restriction. uframe 0-5 are possible. The idea of this patch is that the first uframe are precious (for IN TT iso stream) and we should allocate the last uframes first if possible. For that we reverse the order of uframe allocation (last uframe first).

2011-11-26usb-storage: Accept 8020i-protocol commands longer than 12 bytesAlan Stern
commit 2f640bf4c94324aeaa1b6385c10aab8c5ad1e1cf upstream. The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands; shorter commands must be padded. Simon Detheridge reports that his 3-TB USB disk drive claims to use the 8020i protocol (which is normally meant for ATAPI devices like CD drives), and because of its large size, the disk drive requires the use of 16-byte commands. However the usb_stor_pad12_command() routine in usb-storage always sets the command length to 12, making the drive impossible to use. Since the SFF-8020i specification allows for 16-byte commands in future extensions, we may as well accept them. This patch (as1490) changes usb_stor_pad12_command() to leave commands larger than 12 bytes alone rather than truncating them.

commit b1ffb4c851f185e9051ba837c16d9b84ef688d26 upstream. Fix for ftdi_set_termios() glitching output ftdi_set_termios() is constantly setting the baud rate, data bits and parity unnecessarily on every call, . When called while characters are being transmitted can cause the FTDI chip to corrupt the serial port bit stream output by stalling the output half a bit during the output of a character. Simple fix by skipping this setting if the baud rate/data bits/parity are unchanged. Signed-off-by: Andrew Worsley <amworsley@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-11-26USB: workaround for bug in old version of GCCAlan Stern
commit 97ff22ee3b4cb3a334f7385e269773141aed702f upstream. This patch (as1491) works around a bug in GCC-3.4.6, which is still supposed to be supported. The number of microseconds in the udelay() call in quirk_usb_disable_ehci() is fixed at 100, but the compiler doesn't understand this and generates a link-time error. So we replace the otherwise unused variable "delta" with a simple constant 100. This same pattern is already used in other delay loops in that source file.

commit 5dc2470c602da8851907ec18942cd876c3b4ecc1 upstream. There's a race between the USB disconnect handler and the TTY close handler which may cause the acm object to be freed while it's still being used. This may lead to things like http://article.gmane.org/gmane.linux.usb.general/54250 and https://lkml.org/lkml/2011/5/29/64 This is the simplest fix I could come up with. Holding on to open_mutex while closing the TTY device prevents acm_disconnect() from freeing the acm object between acm->port.count drops to 0 and the TTY side of the cleanups are finalized.

2011-11-26USB: XHCI: resume root hubs when the controller resumesAlan Stern
commit f69e3120df82391a0ee8118e0a156239a06b2afb upstream. This patch (as1494) fixes a problem in xhci-hcd's resume routine. When the controller is runtime-resumed, this can only mean that one of the two root hubs has made a wakeup request and therefore needs to be resumed as well. Rather than try to determine which root hub requires attention (which might be difficult in the case where a new non-SuperSpeed device has been plugged in), the patch simply resumes both root hubs. Without this change, there is a race: The controller might be put back to sleep before it can activate its IRQ line, and the wakeup condition might never get handled. The patch also simplifies the logic in xhci_resume a little, combining some repeated flag settings into a single pair of statements.

What lockdep deduces is that if an interrupt occurred while in this function it would deadlock with xhci_irq because that function also grabs the xhci->lock. Fixing it is trivial by using spin_lock_irqsave instead. This should be queued to stable kernels as far back as 2.6.33.

2011-11-26usb, xhci: Clear warm reset change event during initDon Zickus
commit 79c3dd8150fd5236d95766a9e662e3e932b462c9 upstream. I noticed on my Panther Point system that I wasn't getting hotplug events for my usb3.0 disk on a usb3 port. I tracked it down to the fact that the system had the warm reset change bit still set. This seemed to block future events from being received, including a hotplug event. Clearing this bit during initialization allowed the hotplug event to be received and the disk to be recognized correctly. This patch should be backported to kernels as old as 2.6.39.

The xHCI spec says that both flags must be set to one for the Address Device command. When the device is first enumerated, xhci_setup_addressable_virt_dev() does set those flags. However, when the device is addressed after it has been reset in the configured state, xhci_setup_addressable_virt_dev() is not called, and xhci_copy_ep0_dequeue_into_input_ctx() is called instead. That function relies on the flags being set up by previous commands, which apparently isn't a good assumption. Move the setting of the flags into the common parent function. This should be queued for stable kernels as old as 2.6.35, since that was the first introduction of xhci_copy_ep0_dequeue_into_input_ctx.

2011-11-11USB: Update last_busy time after autosuspend failsAlan Stern
commit b2c0a863e14676fa5760c6d828fd373288e2f64a upstream. Originally, the runtime PM core would send an idle notification whenever a suspend attempt failed. The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. A companion patch changes the PM core's behavior, but we also need to change the USB core. In particular, this patch (as1493) updates the device's last_busy time when an autosuspend fails, so that the PM core will retry the autosuspend in the future when the delay time expires again.

commit 6fd4562178508a0949c9fdecd8558d8b10d671bd upstream. When the link state changes, xHC will report a port status change event and set the PORT_PLC bit, for both USB3 and USB2 root hub ports. The PLC will be cleared by usbcore for USB3 root hub ports, but not for USB2 ports, because they do not report USB_PORT_STAT_C_LINK_STATE in wPortChange. Clear it for USB2 root hub ports in handle_port_status().

2011-11-11xhci: If no endpoints changed, don't issue BW command.Sarah Sharp
commit 2dc3753997f3c80ce8b950242ab9bb3fb936acfd upstream. Some alternate interface settings have no endpoints associated with them. This shows up in some USB webcams, particularly the Logitech HD 1080p, which uses the uvcvideo driver. If a driver switches between two alt settings with no endpoints, there is no need to issue a configure endpoint command, because there is no endpoint information to update. The only time a configure endpoint command with just the add slot flag set makes sense is when the driver is updating hub characteristics in the slot context. However, that code never calls xhci_check_bandwidth, so we should be safe not issuing a command if only the slot context add flag is set.

2011-11-11usb_storage: Don't freeze in usb-stor-scanSeth Forshee
commit f02fe890ece7d695a5744b20525d45312382e6e4 upstream. Scanning cannot be run during suspend or hibernation, but if usb-stor-scan freezes another thread waiting on scanning to complete may fail to freeze. However, if usb-stor-scan is left freezable without ever actually freezing then the freezer will wait on it to exit, and threads waiting for scanning to finish will no longer be blocked. One problem with this approach is that usb-stor-scan has a delay to wait for devices to settle (which is currently the only point where it can freeze). To work around this we can request that the freezer send a fake signal when freezing, then use interruptible sleep to wake the thread early when freezing happens. To make this happen, the following changes are made to usb-stor-scan: * Use set_freezable_with_signal() instead of set_freezable() to request a fake signal when freezing * Use wait_event_interruptible_timeout() instead of wait_event_freezable_timeout() to avoid freezing Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-11-11USB: xHCI: prevent infinite loop when processing MSE eventAndiry Xu
commit c2d7b49f42f50d7fc5cbfd195b785a128723fdf4 upstream. When a xHC host is unable to handle isochronous transfer in the interval, it reports a Missed Service Error event and skips some tds. Currently xhci driver handles MSE event in the following ways: 1. When encounter a MSE event, set ep->skip flag, update event ring dequeue pointer and return. 2. When encounter the next event on this ep, the driver will run the do-while loop, fetch td from ep's td_list to find the td corresponding to this event. All tds missed are marked as short transfer(-EXDEV). The do-while loop will end in two ways: 1. If the td pointed by the event trb is found; 2. If the ep ring's td_list is empty. However, if a buggy HW reports some unpredicted event (for example, an overrun event following a MSE event while the ep ring is actually not empty), the driver will never find the td, and it will loop until the td_list is empty. Unfortunately, the spinlock is dropped when give back a urb in the do-while loop. During the spinlock released period, the class driver may still submit urbs and add tds to the td_list. This may cause disaster, since the td_list will never be empty and the loop never ends, and the system hangs. To fix this, count the number of TDs on the ep ring before skipping TDs, and quit the loop when skipped that number of tds. This guarantees the do-while loop will end after certain number of cycles, and driver will not be trapped in an infinite loop.

commit 2394d67e446bf616a0885167d5f0d397bdacfdfc upstream. The new runtime PM code has shown that many webcams suffer from a race condition that may crash them upon resume. Runtime PM is especially prone to show the problem because it retains power to the cameras at all times. However system suspension may also crash the devices and retain power to the devices. The only way to solve this problem without races is in usbcore with the RESET_RESUME quirk. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
