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

2017-11-21T08:21:23+00:00

commit 74d471b598444b7f2d964930f7234779c80960a0 upstream.

Make sure to free the port private data before returning after a failed
probe attempt.

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

2017-11-21T08:21:23+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: usbfs: compute urb->actual_length for isochronous

2017-11-21T08:21:23+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.

ixgbe: Reduce I2C retry count on X550 devices

2017-11-21T08:21:21+00:00

[ Upstream commit 3f0d646b720d541309b11e190db58086f446f41e ]

A retry count of 10 is likely to run into problems on X550 devices that
have to detect and reset unresponsive CS4227 devices. So, reduce the I2C
retry count to 3 for X550 and above. This should avoid any possible
regressions in existing devices.

ixgbe: handle close/suspend race with netif_device_detach/present

2017-11-21T08:21:21+00:00

[ Upstream commit f7f37e7ff2b9b7eff7fbd035569cab35896869a3 ]

When an interface is part of a namespace it is possible that
ixgbe_close() may be called while __ixgbe_shutdown() is running
which ends up in a double free WARN and/or a BUG in free_msi_irqs().

To handle this situation we extend the rtnl_lock() to protect the
call to netif_device_detach() and ixgbe_clear_interrupt_scheme()
in __ixgbe_shutdown() and check for netif_device_present()
to avoid clearing the interrupts second time in ixgbe_close();

Also extend the rtnl lock in ixgbe_resume() to netif_device_attach().
