To avoid buffer overflow while reading a corrupted or possibly
modified port file we validate the length of each part of the port
record to ensure it doesn't exceed the length of the destination
buffer.

This driver was previously an interface driver. Since USB/IP
exports a whole device, not just an interface, it would make
sense to be a device driver.
This patch also modifies the way userspace sees and uses a
shared device:
* the usbip_status file is no longer created for interface 0, but for
the whole device (such as
/sys/devices/pci0000:00/0000:00:01.2/usb1/1-1/usbip_status).
* per interface information, such as interface class or protocol, is
no longer sent/received; only device specific information is
transmitted.
* since the driver was moved one level below in the USB architecture,
there is no need to bind/unbind each interface, just the device as a
whole.

include speed string
Change vhci_hcd store_attach() routine to include speed string in its device
information message. The current call to dev_info() prints out speed number
which is the enum number. Change to call usb_speed_string() to print speed
string in addition to the number.

As of Matt Mooney's major refactoring in 2011, usbip port
option was left out. Add support for this option in
a manner similar to the old implementation.

getaddrinfo() leaves the order of the returned addrinfo structs
unspecified. On systems with bindv6only disabled (this is the default),
PF_INET6 sockets bind to IPv4, too. Thus, IPv6 support in usbipd was
broken when getaddrinfo returned first IPv4 and then IPv6 addrinfos, as
the IPv6 bind failed with EADDRINUSE.
This patch uses seperate sockets for IPv4 and IPv6 and sets IPV6_V6ONLY
on all IPv6 sockets. Two command line arguments, -4 and -6 were added to
manually select the socket family.

The `usbip list -l' command shows your local usb-devices.
Example:
$ usbip list -l
$ Local USB devices
$ =================
$ - busid 1-1 (13fe:1d00)
$ 1-1:1.0 -> usb-storage
$
$ - busid 1-2 (0409:55aa)
$ 1-2:1.0 -> hub
However this list command doesn't show which device is connected
to this busid. Therefore you have to use another tool e.g. lsusb
to determine that.
This patches adds the possibility to see which device that is.
Example:
$ usbip list -l
$ Local USB devices
$ =================
$ - busid 1-1 (13fe:1d00)
$ Kingston Technology Company Inc. : DataTraveler 2.0 1GB/4GB Flash Drive / Patriot Xporter 4GB Flash
$ 1-1:1.0 -> usb-storage
$
$ - busid 1-2 (0409:55aa)
$ NEC Corp. : Hub (0409:55aa)
$ 1-2:1.0 -> hub

The command `usbip attach' uses --host for specifing
the remote host, while `usbip list' uses --remote.
This is confusing and this patch adapts this.
In Addition changed the manpage and README accordingly.
Before:
$ usbip attach --host <host> -b <busid>
$ usbip list --remote <host>
Now:
$ usbip attach --remote <host> -b <busid>

Since the names.c/names.h are taken from another project, some
functions which names.c provides aren't used by usbipd.
This patch fixes:
- removed useless comments
- unified debug/error messages by using the macros
provided by usbip_common.h
- removed unnused code
The code cleanup includes:
- remove unused data structures
- remove code to create them
- remove code to access them
The file names.c is used to parse the `usb.ids' file. The parser
stores a lot of information about usb devices that is never used.
The `usb.ids' file has several sections. Some variables (like
`lasthut') store the ID of the current section, and those variables
are used to decide which section is currently being parsed (i.e. in
which data structure the current line will be stored).
We removed the code to read those IDs because they are never used
anyway. We replaced them by the pseudo-ID `1' (instead of reading the
ID from the file) to indicate that the parser is in a section that
can be ignored. If the parser is in such a section, the current line
(which contains sub-items for this section) is discarded.
