A recent cleanup moved MAX_IPTUN_ENCAP_OPS along with some other definitions, but it is now invisible when CONFIG_INET is not defined, but still referenced from ip6_tunnel.h: In file included from net/xfrm/xfrm_input.c:17:0: include/net/ip6_tunnel.h:67:17: error: 'MAX_IPTUN_ENCAP_OPS' undeclared here (not in a function) ip6tun_encaps[MAX_IPTUN_ENCAP_OPS]; ^~~~~~~~~~~~~~~~~~~ This hides the ip6_encap_hlen and ip6_tnl_encap functions inside of CONFIG_INET so we don't run into the the problem. Alternatively we could move the macro out of the #ifdef again to restore the previous behavior Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 55c2bc143224 ("net: Cleanup encap items in ip_tunnels.h") --- include/net/ip6_tunnel.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) -- 2.7.0
