2016-05-05usb: hcd: out of bounds access in for_each_companionRobert Dobrowolski1-0/+9
commit e86103a75705c7c530768f4ffaba74cf382910f2 upstream. On BXT platform Host Controller and Device Controller figure as same PCI device but with different device function. HCD should not pass data to Device Controller but only to Host Controllers. Checking if companion device is Host Controller, otherwise skip.

2016-04-12usb: retry reset if a device times outOliver Neukum1-1/+7
commit 264904ccc33c604d4b3141bbd33808152dfac45b upstream. Some devices I got show an inability to operate right after power on if they are already connected. They are beyond recovery if the descriptors are requested multiple times. So in case of a timeout we rather bail early and reset again. But it must be done only on the first loop lest we get into a reset/time out spiral that can be overcome with a retry. This patch is a rework of a patch that fell through the cracks. http://www.spinics.net/lists/linux-usb/msg103263.html Signed-off-by: Oliver Neukum <oneukum@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-03-10target: Add TFO->abort_task for aborted task resources releaseNicholas Bellinger1-0/+6
commit 131e6abc674edb9f9a59090bb35bf6650569b7e7 upstream. Now that TASK_ABORTED status is not generated for all cases by TMR ABORT_TASK + LUN_RESET, a new TFO->abort_task() caller is necessary in order to give fabric drivers a chance to unmap hardware / software resources before the se_cmd descriptor is released via the normal TFO->release_cmd() codepath. This patch adds TFO->aborted_task() in core_tmr_abort_task() in place of the original transport_send_task_abort(), and also updates all fabric drivers to implement this caller. The fabric drivers that include changes to perform cleanup via ->aborted_task() are: - iscsi-target - iser-target - srpt - tcm_qla2xxx The fabric drivers that currently set ->aborted_task() to NOPs are: - loopback - tcm_fc - usb-gadget - sbp-target - vhost-scsi For the latter five, there appears to be no additional cleanup required before invoking TFO->release_cmd() to release the se_cmd descriptor. v2 changes: - Move ->aborted_task() call into transport_cmd_finish_abort (Alex) Cc: Alex Leung <amleung21@yahoo.com> Cc: Mark Rustad <mark.d.rustad@intel.com> Cc: Roland Dreier <roland@kernel.org> Cc: Vu Pham <vu@mellanox.com> Cc: Chris Boot <bootc@bootc.net> Cc: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Michael S.

2016-03-10usb: chipidea: otg: change workqueue ci_otg as freezablePeter Chen1-1/+1
commit d144dfea8af7108f613139623e63952ed7e69c0c upstream. If we use USB ID pin as wakeup source, and there is a USB block device on this USB OTG (ID) cable, the system will be deadlock after system resume. The root cause for this problem is: the workqueue ci_otg may try to remove hcd before the driver resume has finished, and hcd will disconnect the device on it, then, it will call device_release_driver, and holds the device lock "dev->mutex", but it is never unlocked since it waits workqueue writeback to run to flush the block information, but the workqueue writeback is freezable, it is not thawed before driver resume has finished. When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it tries to get its device lock "dev->mutex", but it can't get it forever, then the deadlock occurs. Below call stacks show the situation. So, in order to fix this problem, we need to change workqueue ci_otg as freezable, then the work item in this workqueue will be run after driver's resume, this workqueue will not be blocked forever like above case since the workqueue writeback has been thawed too. Tested at: i.mx6qdl-sabresd and i.mx6sx-sdb.

2016-02-17xhci: fix usb2 resume timing and races.Mathias Nyman2-6/+42
commit f69115fdbc1ac0718e7d19ad3caa3da2ecfe1c96 upstream. According to USB 2 specs ports need to signal resume for at least 20ms, in practice even longer, before moving to U0 state. Both host and devices can initiate resume. On device initiated resume, a port status interrupt with the port in resume state in issued. The interrupt handler tags a resume_done[port] timestamp with current time + USB_RESUME_TIMEOUT, and kick roothub timer. Root hub timer requests for port status, finds the port in resume state, checks if resume_done[port] timestamp passed, and set port to U0 state. On host initiated resume, current code sets the port to resume state, sleep 20ms, and finally sets the port to U0 state. This should also be changed to work in a similar way as the device initiated resume, with timestamp tagging, but that is not yet tested and will be a separate fix later. There are a few issues with this approach 1. A host initiated resume will also generate a resume event. The event handler will find the port in resume state, believe it's a device initiated resume, and act accordingly. 2. A port status request might cut the resume signalling short if a get_port_status request is handled during the host resume signalling. The port will be found in resume state. The timestamp is not set leading to time_after_eq(jiffies, timestamp) returning true, as timestamp = 0. get_port_status will proceed with moving the port to U0. 3. If an error, or anything else happens to the port during device initiated resume signalling it will leave all the device resume parameters hanging uncleared, preventing further suspend, returning -EBUSY, and cause the pm thread to busyloop trying to enter suspend. Fix this by using the existing resuming_ports bitfield to indicate that resume signalling timing is taken care of. Check if the resume_done[port] is set before using it for timestamp comparison, and also clear out any resume signalling related variables if port is not in U0 or Resume state This issue was discovered when a PM thread busylooped, trying to runtime suspend the xhci USB 2 roothub on a Dell XPS Reported-by: Daniel J Blueman <daniel@quora.org> Tested-by: Daniel J Blueman <daniel@quora.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-01-23USB: add quirk for devices with broken LPMAlan Stern2-1/+12
commit ad87e03213b552a5c33d5e1e7a19a73768397010 upstream. Some USB device / host controller combinations seem to have problems with Link Power Management. For example, Steinar found that his xHCI controller wouldn't handle bandwidth calculations correctly for two video cards simultaneously when LPM was enabled, even though the bus had plenty of bandwidth available. This patch introduces a new quirk flag for devices that should remain disabled for LPM, and creates quirk entries for Steinar's devices.

commit a0e80fbd56b4573de997c9a088a33abbc1121400 upstream. The flash loader has been seen on a Telit UE910 modem. The flash loader is a bit special, it presents both an ACM and CDC Data interface but only the latter is useful. Unless a magic string is sent to the device it will disappear and the regular modem device appears instead.

2016-01-23USB: cdc_acm: Ignore Infineon Flash Loader utilityJonas Jonsson1-0/+5
commit f33a7f72e5fc033daccbb8d4753d7c5c41a4d67b upstream. Some modems, such as the Telit UE910, are using an Infineon Flash Loader utility. It has two interfaces, 2/2/0 (Abstract Modem) and 10/0/0 (CDC Data). The latter can be used as a serial interface to upgrade the firmware of the modem. However, that isn't possible when the cdc-acm driver takes control of the device. The following is an explanation of the behaviour by Daniele Palmas during discussion on linux-usb. "This is what happens when the device is turned on (without modifying the drivers): [155492.352031] usb 1-3: new high-speed USB device number 27 using ehci-pci [155492.485429] usb 1-3: config 1 interface 0 altsetting 0 endpoint 0x81 has an invalid bInterval 255, changing to 11 [155492.485436] usb 1-3: New USB device found, idVendor=058b, idProduct=0041 [155492.485439] usb 1-3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [155492.485952] cdc_acm 1-3:1.0: ttyACM0: USB ACM device This is the flashing device that is caught by the cdc-acm driver. Once the ttyACM appears, the application starts sending a magic string (simple write on the file descriptor) to keep the device in flashing mode. If this magic string is not properly received in a certain time interval, the modem goes on in normal operative mode: [155493.748094] usb 1-3: USB disconnect, device number 27 [155494.916025] usb 1-3: new high-speed USB device number 28 using ehci-pci [155495.059978] usb 1-3: New USB device found, idVendor=1bc7, idProduct=0021 [155495.059983] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [155495.059986] usb 1-3: Product: 6 CDC-ACM + 1 CDC-ECM [155495.059989] usb 1-3: Manufacturer: Telit [155495.059992] usb 1-3: SerialNumber: 359658044004697 [155495.138958] cdc_acm 1-3:1.0: ttyACM0: USB ACM device [155495.140832] cdc_acm 1-3:1.2: ttyACM1: USB ACM device [155495.142827] cdc_acm 1-3:1.4: ttyACM2: USB ACM device [155495.144462] cdc_acm 1-3:1.6: ttyACM3: USB ACM device [155495.145967] cdc_acm 1-3:1.8: ttyACM4: USB ACM device [155495.147588] cdc_acm 1-3:1.10: ttyACM5: USB ACM device [155495.154322] cdc_ether 1-3:1.12 wwan0: register 'cdc_ether' at usb-0000:00:1a.7-3, Mobile Broadband Network Device, 00:00:11:12:13:14 Using the cdc-acm driver, the string, though being sent in the same way than using the usb-serial-simple driver (I can confirm that the data is passing properly since I used an hw usb sniffer), does not make the device to stay in flashing mode."

2015-12-09usb: musb: core: fix order of arguments to ulpi write callbackUwe Kleine-König1-5/+5
commit 705e63d2b29c8bbf091119084544d353bda70393 upstream. There is a bit of a mess in the order of arguments to the ulpi write callback. There is int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val) in drivers/usb/common/ulpi.c; struct usb_phy_io_ops { ... int (*write)(struct usb_phy *x, u32 val, u32 reg); } in include/linux/usb/phy.h. The callback registered by the musb driver has to comply to the latter, but up to now had "offset" first which effectively made the function broken for correct users. So flip the order and while at it also switch to the parameter names of struct usb_phy_io_ops's write.
