usbip: Fix potential format overflow in userspace tools

2017-03-17T04:16:56Z

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().

usbip: tools: Extract generic code to be shared with vudc backend

2016-04-26T22:19:50Z

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.
