From 7acc0bb490c85012bcbda142b6755fd1fdf1fba1 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 27 Apr 2021 21:45:19 +0200 Subject: [PATCH] netfilter: nft_socket: fix build with CONFIG_SOCK_CGROUP_DATA=n In some configurations, the sock_cgroup_ptr() function is not available: net/netfilter/nft_socket.c: In function 'nft_sock_get_eval_cgroupv2': net/netfilter/nft_socket.c:47:16: error: implicit declaration of function 'sock_cgroup_ptr'; did you mean 'obj_cgroup_put'? [-Werror=implicit-function-declaration] 47 | cgrp = sock_cgroup_ptr(&sk->sk_cgrp_data); | ^~~~~~~~~~~~~~~ | obj_cgroup_put net/netfilter/nft_socket.c:47:14: error: assignment to 'struct cgroup *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion] 47 | cgrp = sock_cgroup_ptr(&sk->sk_cgrp_data); | ^ Change the caller to match the same #ifdef check, only calling it when the function is defined.
