Add the missing flag that was left out as an exercise for the reader :) Cc: Vlad Buslov Fixes: 8f84780b84d6 ("netfilter: flowtable: allow unidirectional rules") Reported-by: Daniel Golle Signed-off-by: Felix Fietkau Signed-off-by: Pablo Neira Ayuso --- diff --git a/net/netfilter/nft_flow_offload.c b/net/netfilter/nft_flow_offload.c index 397351fa4d5f..ab9576098701 100644 --- a/net/netfilter/nft_flow_offload.c +++ b/net/netfilter/nft_flow_offload.c @@ -361,6 +361,7 @@ static void nft_flow_offload_eval(const struct nft_expr *expr, ct->proto.tcp.seen[1].flags |= IP_CT_TCP_FLAG_BE_LIBERAL; } + __set_bit(NF_FLOW_HW_BIDIRECTIONAL, &flow->flags); ret = flow_offload_add(flowtable, flow); if (ret < 0) goto err_flow_add;
