2012-11-19pidns: Use task_active_pid_ns where appropriateEric W. Biederman1-1/+2
The expressions tsk->nsproxy->pid_ns and task_active_pid_ns aka ns_of_pid(task_pid(tsk)) should have the same number of cache line misses with the practical difference that ns_of_pid(task_pid(tsk)) is released later in a processes life. Furthermore by using task_active_pid_ns it becomes trivial to write an unshare implementation for the the pid namespace. So I have used task_active_pid_ns everywhere I can. In fork since the pid has not yet been attached to the process I use ns_of_pid, to achieve the same effect. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>

2012-10-26net: usb: Fix memory leak on Tx data pathHemant Kumar1-0/+3
Driver anchors the tx urbs and defers the urb submission if a transmit request comes when the interface is suspended. Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

2012-10-26bas_gigaset: fix pre_reset handlingTilman Schmidt1-3/+16
The delayed work function int_in_work() may call usb_reset_device() and thus, indirectly, the driver's pre_reset method. Trying to cancel the work synchronously in that situation would deadlock. Fix by avoiding cancel_work_sync() in the pre_reset method. If the reset was NOT initiated by int_in_work() this might cause int_in_work() to run after the post_reset method, with urb_int_in already resubmitted, so handle that case gracefully.

2012-10-26Input: wacom - handle split-sensor devices with internal hubsJason Gerecke3-2/+35
Like our other pen-and-touch products, the Cintiq 24HD touch needs data to be shared between its two sensors to facilitate proximity-based palm rejection. Unlike other tablets that report sensor data through separate interfaces of the same USB device, the Cintiq 24HD touch has separate USB devices that are connected to an internal USB hub. This patch makes it possible to designate the USB VID/PID of the other device so that the two may share data. To ensure we don't accidentally link to a sensor from a physically separate device (if several have been plugged in), we limit the search to siblings (i.e., devices directly connected to the same hub).

2012-10-26drivers/dma/dw_dmac: make driver's endianness configurableHein Tibosch2-5/+24
The dw_dmac driver was originally developed for avr32 to be used with the Synopsys DesignWare AHB DMA controller. Starting from 2.6.38, access to the device's i/o memory was done with the little-endian readl/writel functions(1) This broke the driver for the avr32 platform, because it needs big (native) endian accessors. This patch makes the endianness configurable using 'DW_DMAC_BIG_ENDIAN_IO', which will default be true for AVR32 I submitted this patch before(2) but then waited for Andy to finish other changes to the same module(3).

2012-10-26xhci: Fix missing break in xhci_evaluate_context_result.Sarah Sharp1-0/+2
Coverity complains that xhci_evaluate_context_result() is missing a break statement after the COMP_EBADSLT switch case. It's not a big deal, since we wanted to return the same error code as the case statement below it does. The end result would be one that a Slot Disabled error completion code would also print the warning message associated with a Context State error code. No other bad behavior would result. It's not worth backporting to stable kernels, since it only fixes an issue with too much debugging. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
2012-10-26xhci: Fix potential NULL ptr deref in command cancellation.Sarah Sharp1-0/+11
The command cancellation code doesn't check whether find_trb_seg() couldn't find the segment that contains the TRB to be canceled. This could cause a NULL pointer deference later in the function when next_trb is called. It's unlikely to happen unless something is wrong with the command ring pointers, so add some debugging in case it happens. This patch should be backported to stable kernels as old as 3.0, that contain the commit b63f4053cc8aa22a98e3f9a97845afe6c15d0a0d "xHCI: handle command after aborting the command ring".

2012-10-25USB: mos7840: fix port-data memory leakJohan Hovold1-130/+89
Fix port-data memory leak by moving port data allocation and deallocation to port_probe and port_remove. Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible. Note that the indentation was kept intact using a do-while(0) in order to facilitate review. A follow-up patch will remove it. Compile-only tested.

2012-10-25USB: usb-wwan: fix multiple memory leaks in error pathsJohan Hovold5-78/+54
Fix port-data memory leak in usb-serial probe error path by moving port data allocation to port_probe. Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect with a port_remove hook") port data is deallocated in port_remove. This leaves a possibility for memory leaks if usb-serial probe fails after attach but before the port in question has been successfully registered. Note that this patch also fixes two additional memory leaks in the error path of attach should port initialisation fail for any port as the urbs were never freed and neither was the data of any of the successfully initialised ports.
