From 12ad0b6572d0793d0dc100b32caec5a2859399ed Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 11 Jan 2019 12:35:15 -0800 Subject: [PATCH] net/tap: allow full length names The code for set_interface_name was incorrectly assuming that space for null byte was necessary with snprintf/strlcpy.
