USB: serial: garmin_gps: fix memory leak on probe errors

2017-11-21T09:24:35+00:00

commit 74d471b598444b7f2d964930f7234779c80960a0 upstream. Make sure to free the port private data before returning after a failed probe attempt. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: garmin_gps: fix I/O after failed probe and remove

2017-11-21T09:24:35+00:00

commit 19a565d9af6e0d828bd0d521d3bafd5017f4ce52 upstream. Make sure to stop any submitted interrupt and bulk-out URBs before returning after failed probe and when the port is being unbound to avoid later NULL-pointer dereferences in the completion callbacks. Also fix up the related and broken I/O cancellation on failed open and on close. (Note that port->write_urb was never submitted.)

USB: serial: Change DbC debug device binding ID

2017-11-21T09:24:35+00:00

commit 12f28144cf2cf69e1520e238eee7c384719ca44b upstream. The product ID for "Linux USB GDB Target device" has been changed. Change the driver binding table accordingly. This patch should be back-ported to kernels as old as v4.12, that contain the commit 57fb47279a04 ("usb/serial: Add DBC debug device support to usb_debug").

USB: serial: metro-usb: stop I/O after failed open

2017-11-21T09:24:34+00:00

commit 2339536d229df25c71c0900fc619289229bfecf6 upstream. Make sure to kill the interrupt-in URB after a failed open request. Apart from saving power (and avoiding stale input after a later successful open), this also prevents a NULL-deref in the completion handler if the port is manually unbound.

usb: gadget: f_fs: Fix use-after-free in ffs_free_inst

2017-11-21T09:24:34+00:00

commit cdafb6d8b8da7fde266f79b3287ac221aa841879 upstream. KASAN enabled configuration reports an error BUG: KASAN: use-after-free in ffs_free_inst+... [usb_f_fs] at addr ... Write of size 8 by task ... This is observed after "ffs-test" is run and interrupted. If after that functionfs is unmounted and g_ffs module is unloaded, that use-after-free occurs during g_ffs module removal. Although the report indicates ffs_free_inst() function, the actual use-after-free condition occurs in _ffs_free_dev() function, which is probably inlined into ffs_free_inst(). This happens due to keeping the ffs_data reference in device structure during functionfs unmounting, while ffs_data itself is freed as no longer needed. The fix is to clear that reference in ffs_closed() function, which is a counterpart of ffs_ready(), where the reference is stored.

USB: usbfs: compute urb->actual_length for isochronous

2017-11-21T09:24:34+00:00

commit 2ef47001b3ee3ded579b7532ebdcf8680e4d8c54 upstream. The USB kerneldoc says that the actual_length field "is read in non-iso completion functions", but the usbfs driver uses it for all URB types in processcompl(). Since not all of the host controller drivers set actual_length for isochronous URBs, programs using usbfs with some host controllers don't work properly. For example, Minas reports that a USB camera controlled by libusb doesn't work properly with a dwc2 controller. It doesn't seem worthwhile to change the HCDs and the documentation, since the in-kernel USB class drivers evidently don't rely on actual_length for isochronous transfers. The easiest solution is for usbfs to calculate the actual_length value for itself, by adding up the lengths of the individual packets in an isochronous transfer.

USB: early: Use new USB product ID and strings for DbC device

2017-11-21T09:24:34+00:00

commit c67678ec78eff9cf1e7e997fe6c37c9fcccfc5b8 upstream. The DbC register set defines an interface for system software to specify the vendor id and product id for the debug device. These two values will be presented by the debug device in its device descriptor idVendor and idProduct fields. The current used product ID is a place holder. We now have a valid one. The description strings are changed accordingly. This patch should be back-ported to kernels as old as v4.12, that contain the commit aeb9dd1de98c ("usb/early: Add driver for xhci debug capability").

usb: usbtest: fix NULL pointer dereference

2017-11-18T10:30:40+00:00

commit 7c80f9e4a588f1925b07134bb2e3689335f6c6d8 upstream. If the usbtest driver encounters a device with an IN bulk endpoint but no OUT bulk endpoint, it will try to dereference a NULL pointer (out->desc.bEndpointAddress). The problem can be solved by adding a missing test.
