commit e5dfa3f902b9a642ae8c6997d57d7c41e384a90b upstream.
The usbip userspace tools call sprintf()/snprintf() and don't check for
the return value which can lead the paths to overflow, truncating the
final file in the path.
More urgently, GCC 7 now warns that these aren't checked with
-Wformat-overflow, and with -Werror enabled in configure.ac, that makes
these tools unbuildable.
This patch fixes these problems by replacing sprintf() with snprintf() in
one place and adding checks for the return value of snprintf().

commit 2f2d0088eb93db5c649d2a5e34a3800a8a935fc5 upstream.
When a client has a USB device attached over IP, the vhci_hcd driver is
locally leaking a socket pointer address via the
/sys/devices/platform/vhci_hcd/status file (world-readable) and in debug
output when "usbip --debug port" is run.
Fix it to not leak. The socket pointer address is not used at the moment
and it was made visible as a convenient way to find IP address from socket
pointer address by looking up /proc/net/{tcp,tcp6}.
As this opens a security hole, the fix replaces socket pointer address with
sockfd.

Adds an equivalent of usbip_host_driver for the vudc. Most
of the code is already shared, but this adds some vudc specific
code for getting information about devices.

Extract the code from current stub driver backend and a common
interface for both stub driver and vudc. This allows to share most
of the usbipd code for both of them.

and can be moved out of staging.
