From f8916707045170b2509c34f0d72f9bb4dae463f6 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 27 Nov 2018 23:40:21 +0100 Subject: [PATCH] kernel: netfilter: Adapt merge ipv4/ipv6 masquerade code In kernel commit 0168e8b361 ("netfilter: nat: merge ipv4/ipv6 masquerade code into main nat module") the CONFIG_NF_NAT_MASQUERADE_IPV4 and CONFIG_NF_NAT_MASQUERADE_IPV6 kernel configuration option were changed to bool and the code will not be compiled as a own module any more, but it will be integrated into nf_nat_ipv4.ko or nf_nat_ipv6.ko to save some memory. Activate these options as bool in the generic kernel 4.19 configuration only, to always build them into the nf_nat_ipv*.ko modules. The kmod file will still try to select them as module, but the generic configuration will not be overwritten.
