From 3c60a17b1b55ac4a72382502c952222b7649d63b Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 1 Apr 2012 18:48:06 -0400 Subject: [PATCH] nf_conntrack_proto_udp{,lite}: 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.
