From bda7102d60bfdab2aa3f36ebd09a119206f264d0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Carlos=20Falgueras=20Garc=C3=ADa?= Date: Mon, 11 Jul 2016 18:07:40 +0200 Subject: src: Fix nftnl_*_get_data() to return the real attribute length MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All getters must set the memory size of the attributes, ie. this includes the nul-termination in strings. For references to opaque objects hidden behind the curtain, report a zero size.
