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.

usbip: move usbip userspace code out of staging2014-08-25T17:38:56+00:00Valentina Maneavalentina.manea.m@gmail.com2014-08-20T04:30:59+00:00urn:sha1:588b48caf65c4a92af567948ec0025065e749ddf
At this point, USB/IP userspace code is fully functional
and can be moved out of staging.
