From b0366b08a206039dc73c08678af77916a06cf655 Mon Sep 17 00:00:00 2001 From: Kyrylo Yatsenko Date: Thu, 4 Sep 2025 09:01:13 +0300 Subject: [PATCH] flows_dump_seq_show: fix table when no VLAN When no VLAN nothing was output, so columns were off. Output "-" when no VLAN so that tools can parse table properly. --- ipt_NETFLOW.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/ipt_NETFLOW.c b/ipt_NETFLOW.c index 3c9cc05..21b65ac 100644 --- a/ipt_NETFLOW.c +++ b/ipt_NETFLOW.c @@ -1153,6 +1153,8 @@ static int flows_dump_seq_show(struct seq_file *seq, void *v) seq_printf(seq, " %d", ntohs(nf->tuple.tag[0])); if (nf->tuple.tag[1]) seq_printf(seq, ",%d", ntohs(nf->tuple.tag[1])); + } else { + seq_printf(seq, " -"); } #endif #if defined(ENABLE_MAC) || defined(ENABLE_VLAN)
