* usbnet: don't clear urb->dev in tx_completetom.leiming@gmail.com2012-04-02
| | | | | | | | | | | | | | | | | | commit 5d5440a835710d09f0ef18da5000541ec98b537a upstream. URB unlinking is always racing with its completion and tx_complete may be called before or during running usb_unlink_urb, so tx_complete must not clear urb->dev since it will be used in unlink path, otherwise invalid memory accesses or usb device leak may be caused inside usb_unlink_urb.

* usbnet: increase URB reference count before usb_unlink_urbtom.leiming@gmail.com2012-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 0956a8c20b23d429e79ff86d4325583fc06f9eb4 upstream. Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock, but it makes usb_unlink_urb racing with defer_bh, and the URB to being unlinked may be freed before or during calling usb_unlink_urb, so use-after-free problem may be triggerd inside usb_unlink_urb. The patch fixes the use-after-free problem by increasing URB reference count with skb queue lock held before calling usb_unlink_urb, so the URB won't be freed until return from usb_unlink_urb.

| | | | | | | | | | | | | | | | | commit a29852be492d61001d86c6ebf5fff9b93d7b4be9 upstream. Two bad things can happen in ubi_scan(): 1. If kmem_cache_create() fails we jump to out_si and call ubi_scan_destroy_si() which calls kmem_cache_destroy(). But si->scan_leb_slab is NULL. 2. If process_eb() fails we jump to out_vidh, call kmem_cache_destroy() and ubi_scan_destroy_si() which calls again kmem_cache_destroy().

* firewire: ohci: fix too-early completion of IR multichannel buffersClemens Ladisch2012-04-02
| | | | | | | | | | | | | | | | | | | | | | | commit 0c0efbacab8d70700d13301e0ae7975783c0cb0a upstream. handle_ir_buffer_fill() assumed that a completed descriptor would be indicated by a non-zero transfer_status (as in most other descriptors). However, this field is written by the controller as soon as (the end of) the first packet has been written into the buffer. As a consequence, if we happen to run into such a descriptor when the interrupt handler is executed after such a packet has completed, the descriptor would be taken out of the list of active descriptors as soon as the buffer had been partially filled, so the event for the buffer being completely filled would never be sent. To fix this, handle descriptors only when they have been completely filled, i.e., when res_count == 0. (This also matches the condition that is reported by the controller with an interrupt.)

* md/raid1,raid10: avoid deadlock during resync/recovery.NeilBrown2012-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit d6b42dcb995e6acd7cc276774e751ffc9f0ef4bf upstream. If RAID1 or RAID10 is used under LVM or some other stacking block device, it is possible to enter a deadlock during resync or recovery. This can happen if the upper level block device creates two requests to the RAID1 or RAID10. The first request gets processed, blocks recovery and queue requests for underlying requests in current->bio_list. A resync request then starts which will wait for those requests and block new IO. But then the second request to the RAID1/10 will be attempted and it cannot progress until the resync request completes, which cannot progress until the underlying device requests complete, which are on a queue behind that second request. So allow that second request to proceed even though there is a resync request about to start. This is suitable for any -stable kernel.

* tcm_fc: Fix fc_exch memory leak in ft_send_resp_statusNicholas Bellinger2012-04-02
| | | | | | | | | | | | | | | | | | | | | | commit 031ed4d565b31880a4136bb7366bc89f5b1dba7d upstream. This patch fixes a bug in tcm_fc where fc_exch memory from fc_exch_mgr->ep_pool is currently being leaked by ft_send_resp_status() usage. Following current code in ft_queue_status() response path, using lport->tt.seq_send() needs to be followed by a lport->tt.exch_done() in order to release fc_exch memory back into libfc_em kmem_cache. ft_send_resp_status() code is currently used in pre submit se_cmd ft_send_work() error exceptions, TM request setup exceptions, and main TM response callback path in ft_queue_tm_resp(). This bugfix addresses the leak in these cases.

* udlfb: remove sysfs framebuffer device with USB .disconnect()Kay Sievers2012-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit ce880cb860f36694d2cdebfac9e6ae18176fe4c4 upstream. The USB graphics card driver delays the unregistering of the framebuffer device to a workqueue, which breaks the userspace visible remove uevent sequence. Recent userspace tools started to support USB graphics card hotplug out-of-the-box and rely on proper events sent by the kernel. The framebuffer device is a direct child of the USB interface which is removed immediately after the USB .disconnect() callback. But the fb device in /sys stays around until its final cleanup, at a time where all the parent devices have been removed already. To work around that, we remove the sysfs fb device directly in the USB .disconnect() callback and leave only the cleanup of the internal fb data to the delayed work. Before: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) remove /2-1.2:1.0/graphics/fb0 (graphics) After: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) Tested-by: Bernie Thompson <bernie@plugable.com> Acked-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This means that there is window where there are no posted receive buffers on the initiator side, so it's possible for the iSER RC connection to break because of RNR NAK / retry errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | commit a5360a53a7ccad5ed9ccef210b94fef13c6e5529 upstream. This patch updates the cp210x driver to support CP210x multiple interface devices devices from Silicon Labs. The existing driver always sends control requests to interface 0, which is hardcoded in the usb_control_msg function calls. This only allows for single interface devices to be used, and causes a bug when using ports on an interface other than 0 in the multiple interface devices. Here are the changes included in this patch: - Updated the device list to contain the Silicon Labs factory default VID/PID for multiple interface CP210x devices - Created a cp210x_port_private struct created for each port on startup, this struct holds the interface number - Added a cp210x_release function to clean up the cp210x_port_private memory created on startup - Modified usb_get_config and usb_set_config to get a pointer to the cp210x_port_private struct, and use the interface number there in the usb_control_message wIndex param Signed-off-by: Preston Fick <preston.fick@silabs.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* USB: qcserial: don't grab QMI port on Gobi 1000 devicesDan Williams2012-04-02
| | | | | | | | | | | | | | | | commit c192c8e71a2ded01170c1a992cd21aaedc822756 upstream. Gobi 1000 devices have a different port layout, which wasn't respected by the current driver, and thus it grabbed the QMI/net port. In the near future we'll be attaching another driver to the QMI/net port for these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver doesn't claim them. This patch also prevents qcserial from binding to interfaces 0 and 1 on 1K devices because those interfaces do not respond.

The pdev_archdata is related to specific platform, it should NOT be accessed by cross platform drivers, like USB. The code for pdev_archdata should be useless, as for PowerPC, it has already gotten the value for pdev->dev.dma_mask at function arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.

Move lock to beginning of hardware visit (fsl_queue_td). - Change the memory flag which using to allocate dTD descriptor buffer, the memory flag can be from gadget layer.
