* usb: gadget: g_ether: fix frame size check for 802.1QIan Coolidge2012-11-07
| | | | | | | | | Checking skb->len against ETH_FRAME_LEN assumes a 1514 ethernet frame size. With an 802.1Q VLAN header, ethernet frame length can now be 1518. Validate frame length against that.

* xhci: Fix missing break in xhci_evaluate_context_result.Sarah Sharp2012-10-25
| | | | | | | | | | | | | | | 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>
* xhci: Fix potential NULL ptr deref in command cancellation.Sarah Sharp2012-10-25
| | | | | | | | | | | | | | | 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".

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.

* USB: usb-wwan: fix multiple memory leaks in error pathsJohan Hovold2012-10-25
| | | | | | | | | | | | | | | | | | | | 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.
