With the addition of VUDC, the USBIP stack can now be used on
configurations without USB host support, but trying to build
it with USB gadget support disabled fails with

This addresses both issues, by changing the dependency for USBIP_CORE
to USB_COMMON, and adding additional dependencies on USB or USB_GADGET
for the individual portions as needed.

This patch adds a code fragment to ignore completing URBs in closing
connection.
Regarding this patch, 2 execution contexts are related.
1) stub_tx.c: stub_complete() which is called from USB core
1-1) add to unlink list and free URB or
1-2) move to tx list
2) stub_dev.c: stub_shutdown_connection() which is invoked by unbind
operation through sysfs.
2-1) stop TX/RX threads
2-2) close TCP connection and set ud.tcp_socket to NULL
2-3) cleanup pending URBs by stub_device_cleanup_urbs(sdev)
2-4) free unlink list (no lock)
In the race condition, URBs which will be cleared in 2-3) may be
handled in 1).
In case 1-1), it will not be transferred bcause tx threads are stooped
in 2-1).
In case 1-2), may be freed in 2-4).
With this patch, after 2-2), completing URBs in 1) will not be handled
and cleared in 2-3).

Dear all,
1. Overview
In current USB/IP implementation, event kernel threads are created for
each port. The functions of the threads are closing connection and
error handling so they don't have not so many events to handle. There's
no need to have thread for each port.
BEFORE) vhci side - VHCI_NPORTS(8) threads are created.
$ ps aux | grep usbip
root 10059 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10060 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10061 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10062 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10063 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10064 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10065 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
root 10066 0.0 0.0 0 0 ? S 17:06 0:00 [usbip_eh]
BEFORE) stub side - threads will be created every bind operation.
$ ps aux | grep usbip
root 8368 0.0 0.0 0 0 ? S 17:56 0:00 [usbip_eh]
root 8399 0.0 0.0 0 0 ? S 17:56 0:00 [usbip_eh]
This patch put event threads of stub and vhci driver as one workqueue.
AFTER) only one event threads in each vhci and stub side.
$ ps aux | grep usbip
root 10457 0.0 0.0 0 0 ? S< 17:47 0:00 [usbip_event]
2. Modification to usbip_event.c
BEFORE) kernel threads are created in usbip_start_eh().
AFTER) one workqueue is created in new usbip_init_eh().
Event handler which was main loop of kernel thread is modified to
workqueue handler.
Events themselves are stored in struct usbip_device - same as before.
usbip_devices which have event are listed in event_list.
The handler picks an element from the list and wakeup usbip_device. The
wakeup method is same as before.
usbip_in_eh() substitutes statement which checks whether functions are
called from eh_ops or not. In this function, the worker context is used
for the checking. The context will be set in a variable in the
beginning of first event handling. usbip_in_eh() is used in event
handler so it works well.
3. Modifications to programs using usbip_event.c
Initialization and termination of workqueue are added to init and exit
routine of usbip_core respectively.

Fix potential out-of-bounds write to urb->transfer_buffer
usbip handles network communication directly in the kernel. When receiving a
packet from its peer, usbip code parses headers according to protocol. As
part of this parsing urb->actual_length is filled. Since the input for
urb->actual_length comes from the network, it should be treated as untrusted.
Any entity controlling the network may put any value in the input and the
preallocated urb->transfer_buffer may not be large enough to hold the data.
Thus, the malicious entity is able to write arbitrary data to kernel memory.

The usbip_protocol.txt, a document which describes usbip's
inner workings is currently located in the projects source
directory (drivers/usb/usbip/...). This patch moves it to
Documentation/usb.
This discussion was brought up by Guy Harris [0] during the
review of the USBIP dissector I wrote. For anyone interested:
support is available with the latest wireshark master/dev tree.
Simply select a packet from the usbip's tcp-stream you are
intrested on and select the USBIP as the protocol in the
"Decode As" dialog box [1].

there, we should return -EIDRM (as per usb_hcd_check_unlink_urb).

In big endian cases, macro cpu_to_le16 unfolds to __swab16 which
provides special case for constants. In little endian cases,
__constant_cpu_to_le16 and cpu_to_le16 expand directly to the
same expression. So, replace __constant_cpu_to_le16 with
cpu_to_le16 with the goal of getting rid of the definition of
__constant_cpu_to_le16 completely.
The semantic patch that performs this transformation is as follows:
@@expression x;@@
- __constant_cpu_to_le16(x)
+ cpu_to_le16(x)
