Some UDC drivers (like the DWC3) expect that the response to a setup()
request is queued from within the setup function itself so that it is
available as soon as setup() has completed.

Upon receiving a setup request the function fs driver creates an event that
is made available to userspace. And only once userspace has acknowledged
that event the response to the setup request is queued.

So it violates the requirement of those UDC drivers and random failures can
be observed. This is basically a race condition and if userspace is able to
read the event and queue the response fast enough all is good. But if it is
not, for example because other processes are currently scheduled to run,
the USB host that sent the setup request will observe an error.

To avoid this the gadget framework provides the USB_GADGET_DELAYED_STATUS
return code. If a setup() callback returns this value the UDC driver is
aware that response is not yet available and can uses the appropriate
methods to handle this case.

Since in the case of function fs the response will never be available when
the setup() function returns make sure that this status code is used.

This fixed random occasional failures that were previously observed on a
DWC3 based system under high system load.

When using a AIO read() operation on the function FS gadget driver a URB is
submitted asynchronously and on URB completion the received data is copied
to the userspace buffer associated with the read operation.

This is done from a kernel worker thread invoking copy_to_user() (through
copy_to_iter()). And while the user space process memory is made available
to the kernel thread using use_mm(), some architecture require in addition
to this that the operation runs with USER_DS set. Otherwise the userspace
memory access will fail.

For example on ARM64 with Privileged Access Never (PAN) and User Access
Override (UAO) enabled the following crash occurs.

	Internal error: Accessing user space memory with fs=KERNEL_DS: 9600004f [#1] SMP
	Modules linked in:

Address this by placing a set_fs(USER_DS) before of the copy operation
and revert it again once the copy operation has finished.

This patch is analogous to commit d7ffde35

 ("vhost: use USER_DS in
vhost_worker thread") which addresses the same underlying issue.

When the host wants to fetch OS descriptors, it sends two requests. The
first is only for the header and the second for the full amount
specified by the header in the first request. The OS descriptor handling
code is distinguishing the header-only requests based on the wLength of
the setup packet, but the same code is executed in both cases to
construct the actual header. Simplify this by always constructing the
header and then filling out the rest of the request if the wLength is
greater than the size of the header.

Also remove the duplicate code for queueing the request to ep0 by adding
a goto label.

When handling an OS descriptor request, one of the first operations is
to zero out the request buffer using the wLength from the setup packet.
There is no bounds checking, so a wLength > 4096 would clobber memory
adjacent to the request buffer. Fix this by taking the min of wLength
and the request buffer length prior to the memset. While at it, define
the buffer length in a header file so that magic numbers don't appear
throughout the code.

When returning data to the host, the data length should be the min of
the wLength and the valid data we have to return. Currently we are
returning wLength, thus requests for a wLength greater than the amount
of data in the OS descriptor buffer would return invalid (albeit zero'd)
data following the valid descriptor data. Fix this by counting the
number of bytes when constructing the data and using this when
determining the length of the request.

pfifo_fast got percpu stats lately, uncovering a bug I introduced last
year in linux-4.10.

I missed the fact that we have to clear our temporary storage
before calling __gnet_stats_copy_basic() in the case of percpu stats.

Without this fix, rate estimators (tc qd replace dev xxx root est 1sec
4sec pfifo_fast) are utterly broken.

Previously, buffer descriptors containing only the frame check sequence
(FCS) were skipped and not added to the skb. However, the page reference
count was still incremented, leading to a memory leak.

Fixing this inside gfar_add_rx_frag() is difficult due to reserved
memory handling and page reuse. Instead, move the FCS handling to
gfar_process_frame() and trim off the FCS before passing the skb up the
networking stack.
