commit dd173abfea upstream.
"param->u.wpa_associate.wpa_ie_len" comes from the user. We should
check it so that the copy_from_user() doesn't overflow the buffer.
Also further down in the function, we assume that if
"param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is
initialized. To make that work, I changed the test here to say that if
"wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return
-EINVAL.
Oddly, we only use the first element of the abyWPAIE[] array. So I
suspect there may be some other issues in this function.

commit 15dd1c9f53 upstream.
Increased storvsc ringbuffer and max_io_requests. This now more
closely mimics the numbers on Hyper-V. And will allow more IO requests
to take place for the SCSI driver.
Max_IO is set to double from what it was before, Hyper-V allows it and
we have had appliance builder requests to see if it was a problem to
increase the number.
Ringbuffer size for storvsc is now increased because I have seen A few buffer
problems on extremely busy systems. They were Set pretty low before.
And since max_io_requests is increased I Really needed to increase the buffer
as well.

commit e5fa721d1c upstream.
Fixed the value of the 64bit-hole inside ring buffer, this
caused a problem on Hyper-V when running checked Windows builds.
Checked builds of Windows are used internally and given to external
system integrators at times. They are builds that for example that all
elements in a structure follow the definition of that Structure. The bug
this fixed was for a field that we did not fill in at all (Because we do
Not use it on the Linux side), and the checked build of windows gives
errors on it internally to the Windows logs.
This fixes that error.

commit b681b5886b upstream.
Fix missing functions for net_device_ops.
It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27,
the default functions for Ethernet, like eth_change_mtu(), were assigned
by ether_setup(). But in 2.6.32, these function pointers moved to
net_device_ops structure and no longer be assigned in ether_setup(). So
we need to set these functions in our driver code. It will ensure the
MTU won't be set beyond 1500. Otherwise, this can cause an error on the
server side, because the HyperV linux driver doesn't support jumbo frame
yet.

This patch prevents the code from calling parport_release and

Rationale:
After the first call the parport is already released and the
handle isn't valid anymore and calling parport_release and
parport_unregister_device twice isn't a good idea.

(Note: upstream comedi configuration has been overhauled, so this patch
does not apply there.)
Several comedi drivers call subdev_8255_init() (declared in
"drivers/staging/comedi/drivers/8255.h") to set up one or more DIO
subdevices. This should be provided by the 8255.ko module, but unless
the CONFIG_COMEDI_8255 or CONFIG_COMEDI_8255_MODULE macro is defined,
the 8255.h header uses a dummy inline version of the function instead.
This means the comedi devices end up with an "unused" subdevice with 0
channels instead of a "DIO" subdevice with 24 channels!
This patch provides a non-interactive COMEDI_8255 option and selects it
whenever the COMEDI_PCI_DRIVERS or COMEDI_PCMCIA_DRIVERS options are
selected.

commit d01f42a22e upstream.
When detaching a port from the client side (usbip --detach 0),
the event thread, on the server side, is going to deadlock.
The "eh" server thread is getting USBIP_EH_RESET event and calls:
-> stub_device_reset() -> usb_reset_device()
the USB framework is then calling back _in the same "eh" thread_ :
-> stub_disconnect() -> usbip_stop_eh() -> wait_for_completion()
the "eh" thread is being asleep forever, waiting for its own completion.
This patch checks if "eh" is the current thread, in usbip_stop_eh().

What's required is setting the flag COMEDI_CB_BLOCK after new data has
