2016-06-01USB: serial: io_edgeport: fix memory leaks in probe error pathJohan Hovold
commit c8d62957d450cc1a22ce3242908709fe367ddc8e upstream. URBs and buffers allocated in attach for Epic devices would never be deallocated in case of a later probe error (e.g. failure to allocate minor numbers) as disconnect is then never called. Fix by moving deallocation to release and making sure that the URBs are first unlinked.

commit 028c49f5e02a257c94129cd815f7c8485f51d4ef upstream. The interface read URB is submitted in attach, but was only unlinked by the driver at disconnect. In case of a late probe error (e.g. due to failed minor allocation), disconnect is never called and we would end up with active URBs for an unbound interface. This in turn could lead to deallocated memory being dereferenced in the completion callback.

commit 35be1a71d70775e7bd7e45fa6d2897342ff4c9d2 upstream. The interface instat and indat URBs were submitted in attach, but never unlinked in release before deallocating the corresponding transfer buffers. In the case of a late probe error (e.g. due to failed minor allocation), disconnect would not have been called before release, causing the buffers to be freed while the URBs are still in use. We'd also end up with active URBs for an unbound interface.

commit 9e45284984096314994777f27e1446dfbfd2f0d7 upstream. The interface read and event URBs are submitted in attach, but were never explicitly unlinked by the driver. Instead the URBs would have been killed by usb-serial core on disconnect. In case of a late probe error (e.g. due to failed minor allocation), disconnect is never called and we could end up with active URBs for an unbound interface.

2016-04-12usb: retry reset if a device times outOliver Neukum
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.

2016-03-09target: Add TFO->abort_task for aborted task resources releaseNicholas Bellinger
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.

2016-03-09usb: chipidea: otg: change workqueue ci_otg as freezablePeter Chen
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.

commit 5c82171167adb8e4ac77b91a42cd49fb211a81a0 upstream. xhci driver frees data for all devices, both usb2 and and usb3 the first time usb_remove_hcd() is called, including td_list and and xhci_ring structures. When usb_remove_hcd() is called a second time for the second xhci bus it will try to dequeue all pending urbs, and touches td_list which is already freed for that endpoint.

2016-02-17xhci: fix usb2 resume timing and races.Mathias Nyman
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>

2016-02-17USB: serial: visor: fix crash on detecting device without write_urbsVladis Dronov
commit cb3232138e37129e88240a98a1d2aba2187ff57c upstream. The visor driver crashes in clie_5_attach() when a specially crafted USB device without bulk-out endpoint is detected. This fix adds a check that the device has proper configuration expected by the driver.

2016-02-17xhci: fix placement of call to usb_disabled()Greg Kroah-Hartman
In the backport of 1eaf35e4dd592c59041bc1ed3248c46326da1f5f, the call to usb_disabled() was too late, after we had already done some allocation. Move that call to the top of the function instead, making the logic match what is intended and is in the original patch.

2016-01-28USB: ipaq.c: fix a timeout loopDan Carpenter
commit abdc9a3b4bac97add99e1d77dc6d28623afe682b upstream. The code expects the loop to end with "retries" set to zero but, because it is a post-op, it will end set to -1. I have fixed this by moving the decrement inside the loop. Fixes: 014aa2a3c32e ('USB: ipaq: minor ipaq_open() cleanup.')

commit 096b110a3dd3c868e4610937c80d2e3f3357c1a9 upstream. if a full speed hub connects to a high speed hub which supports MTT, the MTT field of its slot context will be set to 1 when xHCI driver setups an xHCI virtual device in xhci_setup_addressable_virt_dev(); once usb core fetch its hub descriptor, and need to update the xHC's internal data structures for the device, the HUB field of its slot context will be set to 1 too, meanwhile MTT is also set before, this will cause configure endpoint command fail, so in the case, we should clear MTT to 0 for full speed hub according to section 6.2.2 Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
