From bae65be896cc420f58460cb6f6ac03e71d1bf240 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 1 Apr 2012 18:58:28 -0400 Subject: [PATCH] nf_conntrack_core: Stop using NLA_PUT*(). These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S.
