Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf().

Thanks for the fix.
Would you mind resending with a "staging: greybus: loopback_test:" prefix since this is not a subsystem wide issue, bur rather a bug in a specific user-space tool?
OK, will do that.
Thanks.
Perhaps you should replace the snprintf() at the start of the function in question as well by the way.
