>From 2c3a7d3209ed5e539ecd69192fc0f4186fdc7d99 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A1t=C3=A9=20Eckl?= Date: Thu, 2 Aug 2018 20:46:13 +0200 Subject: [PATCH] netfilter: nft_tproxy: Add missing config check MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A config check was missing form the code when using nf_defrag_ipv6_enable with NFT_TPROXY != n and NF_DEFRAG_IPV6 = n and this caused the following error in case of : ../net/netfilter/nft_tproxy.c: In function 'nft_tproxy_init': ../net/netfilter/nft_tproxy.c:237:3: error: implicit declaration of function +'nf_defrag_ipv6_enable' [-Werror=implicit-function-declaration] err = nf_defrag_ipv6_enable(ctx->net); This patch adds a check for NF_TABLES_IPV6 when NF_DEFRAG_IPV6 is selected by Kconfig.
