* USB: serial/mos*: prevent reading uninitialized stack memoryDan Rosenberg2010-09-262-0/+6
| | | | | | | | | | | | | | commit a0846f1868b11cd827bdfeaf4527d8b1b1c0b098 upstream. The TIOCGICOUNT device ioctl in both mos7720.c and mos7840.c allows unprivileged users to read uninitialized stack memory, because the "reserved" member of the serial_icounter_struct struct declared on the stack is not altered or zeroed before being copied back to the user. This patch takes care of it. Signed-off-by: Dan Rosenberg <dan.j.rosenberg@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* usb: musb_debugfs: don't use the struct file private_data field with seq_filesMathias Nyman2010-09-261-3/+2
| | | | | | | | | | | | commit 024cfa5943a7e89565c60b612d698c2bfb3da66a upstream. seq_files use the private_data field of a file struct for storing a seq_file structure, data should be stored in seq_file's own private field (e.g. file->private_data->private) Otherwise seq_release() will free the private data when the file is closed.

* USB: cdc-acm: Fixing crash when ACM probing interfaces with no endpoint ↵Toby Gray2010-09-201-1/+2
| | | | | | | | | | | | | | | | | | | | | descriptors. commit 577045c0a76e34294f902a7d5d60e90b04d094d0 upstream. Certain USB devices, such as the Nokia X6 mobile phone, don't expose any endpoint descriptors on some of their interfaces. If the ACM driver is forced to probe all interfaces on a device the a NULL pointer dereference will occur when the ACM driver attempts to use the endpoint of the alternative settings. One way to get the ACM driver to probe all the interfaces is by using the /sys/bus/usb/drivers/cdc_acm/new_id interface. This patch checks that the endpoint pointer for the current alternate settings is non-NULL before using it.

* USB: cdc-acm: Adding second ACM channel support for various Nokia and one ↵Toby Gray2010-09-201-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Samsung phones commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream. S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem with a standard AT-command interface, which is picked up correctly by CDC-ACM. The second ACM port is marked as having a vendor-specific protocol. This means that the ACM driver will not claim the second channel by default. This adds support for the second ACM channel for the following devices: Nokia E63 Nokia E75 Nokia 6760 Slide Nokia E52 Nokia E55 Nokia E72 Nokia X6 Nokia N97 Mini Nokia 5800 Xpressmusic Nokia E90 Samsung GTi8510 (INNOV8) Signed-off-by: Toby Gray <toby.gray@realvnc.com> Cc: Oliver Neukum <oliver@neukum.name> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: cxacru: Use a bulk/int URB to access the command endpointSimon Arlott2010-09-201-2/+22
| | | | | | | | | | | | | | | | | | commit 902ffc3c707c1d459ea57428a619a807cbe412f9 upstream. The command endpoint is either a bulk or interrupt endpoint, but using the wrong type of transfer causes an error if CONFIG_USB_DEBUG is enabled after commit f661c6f8c67bd55e93348f160d590ff9edf08904, which checks for this mismatch. Detect which type of endpoint it is and use a bulk/int URB as appropriate. There are other function calls specifying a bulk pipe, but usb_clear_halt doesn't use the pipe type (only the endpoint) and usb_bulk_msg auto-detects interrupt transfers.

* usb: allow drivers to use allocated bandwidth until unboundThadeu Lima de Souza Cascardo2010-09-201-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 0791971ba8fbc44e4f476079f856335ed45e6324 upstream. When using the remove sysfs file, the device configuration is set to -1 (unconfigured). This eventually unbind drivers with the bandwidth_mutex held. Some drivers may call functions that hold said mutex, like usb_reset_device. This is the case for rtl8187, for example. This will lead to the same process holding the mutex twice, which deadlocks. Besides, according to Alan Stern: "The deadlock problem probably could be handled somehow, but there's a separate issue: Until the usb_disable_device call finishes unbinding the drivers, the drivers are free to continue using their allocated bandwidth. We musn't change the bandwidth allocations until after the unbinding is done. So this patch is indeed necessary." Unbinding the driver before holding the bandwidth_mutex solves the problem. If any operation after that fails, drivers are not bound again. But that would be a problem anyway that the user may solve resetting the device configuration to one that works, just like he would need to do in most other failure cases.

| | | | | | | | | | | | | | | | | | | commit a1669b2c64a9c8b031e0ac5cbf2692337a577f7c upstream. The code to increment the TRB pointer has a slight ambiguity that could lead to a bug on different compilers. The ANSI C specification does not specify the precedence of the assignment operator over the postfix operator. gcc 4.4 produced the correct code (increment the pointer and assign the value), but a MIPS compiler that one of John's clients used assigned the old (unincremented) value. Remove the unnecessary assignment to make all compilers produce the correct assembly.

* USB: fix thread-unsafe anchor utiliy routinesChristian Lamparter2010-08-131-29/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | commit b3e670443b7fb8a2d29831b62b44a039c283e351 upstream. This patch fixes a race condition in two utility routines related to the removal/unlinking of urbs from an anchor. If two threads are concurrently accessing the same anchor, both could end up with the same urb - thinking they are the exclusive owner. Alan Stern pointed out a related issue in usb_unlink_anchored_urbs: "The URB isn't removed from the anchor until it completes (as a by-product of completion, in fact), which might not be for quite some time after the unlink call returns. In the meantime, the subroutine will keep trying to unlink it, over and over again."

| | | | | | | | | | | | | | | | | commit afad19648f70c6493193e0a774bd754b7790b4a0 upstream. I have added the ProductID=0xe729 VendorID=FTDI_VID=0x0403 which will enable support for the Segway Robotic Mobility Platform (RMP200) in the ftdi_sio kernel module. Currently, users of the Segway RMP200 must use a RUN+="/sbin/modprobe -q ftdi-sio product=0xe729 vendor=0x0403 in a udev rule to get the ftdi_sio module to handle the usb interface and mount it on /dev/ttyXXX. This is not a good solution because some users will have multiple USB to Serial converters which will use the ftdi_sio module.

| | | | | | | | | | | | | | | | | commit 33d973ad88ceb83ed1449592b7574b5b5bb33ac6 upstream. Enlarging the buffer size via the MON_IOCT_RING_SIZE ioctl causes general protection faults. It appears the culprit is an incorrect argument to mon_free_buff: instead of passing the size of the current buffer being freed, the size of the new buffer is passed. Use the correct size argument to mon_free_buff when changing the size of the buffer.

| | | | | | | | | | | | | | | | | commit ae68a83bdc1971cb02fefc7a686ba6d077065e71 upstream. This patch (as1405) fixes a small bug in ehci-hcd's isochronous scheduler. Not all EHCI controllers are PCI, and the code shouldn't assume that they are. Instead, introduce a special flag for controllers which need to delay iso scheduling for full-speed devices beyond the scheduling threshold.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has different meanings, depending on the endpoint type. If the endpoint is isochronous, the bmAttributes field is the maximum number of packets within a service interval that this endpoint supports. If the endpoint is bulk, it's the number of stream IDs this endpoint supports. Only set the Mult field of the xHCI endpoint context using the bmAttributes field if the endpoint is isochronous, and the device is a SuperSpeed device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a configured device is reset, the control endpoint's ring is reused. If control transfers to the device were issued before the device is reset, the dequeue pointer will be somewhere in the middle of the ring. If the device is then issued an address with the set address command, the xHCI driver must provide a valid input context for control endpoint zero. The original code would give the hardware the original input context, which had a dequeue pointer set to the top of the ring. This would cause the host to re-execute any control transfers until it reached the ring's enqueue pointer. When issuing a set address command for a device that has just been configured and then reset, use the control endpoint's enqueue pointer as the hardware's dequeue pointer. Assumption: All control transfers will be completed or cancelled before the set address command is issued to the device. If there are any outstanding control transfers, this code will not work.

| * USB: Fix USB3.0 Port Speed Downgrade after port resetSarah Sharp2010-07-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this fix, a USB 3.0 port is downgraded to full speed after a port reset of a configured device. The USB 3.0 terminations will be disabled permanently, and USB 3.0 devices will always enumerate as full speed devices, until the host controller is unplugged (if it is an ExpressCard) or the computer is rebooted. Fajun Chen traced this traced the speed downgrade issue to the port reset and the interpretation of port status in USB hub driver code. The hub code was not testing for the port being a SuperSpeed port, and it fell through to the else case of Full Speed. The following patch adds SuperSpeed mapping from the port status, and fixes the speed downgrade issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6c12db90f19727c76990e7f4801c67a148b30111 also seems to have introduced a bug that is triggered when the command ring is about to wrap. The inc_enq() function will not have moved the enqueue pointer past the link TRB. It is supposed to be moved past the link TRB in prepare_ring(), which should be called before a TD is enqueued. However, the queue_command() function never calls the prepare_ring() function because prepare_ring() is only supposed to be used for endpoint rings. That means the enqueue pointer will not be moved past the link TRB, and will get overwritten. The fix is to make queue_command() call prepare_ring() with a fake endpoint status (set to running). Then the enqueue pointer will get moved past the link TRB. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
