Hi,
Static analysis with CoverityScan on net/bridge/br_netlink_tunnel.c has
picked up and issue where tb[] is being referenced but contains
uninitialized data.
222 int br_parse_vlan_tunnel_info(struct nlattr *attr,
223 struct vtunnel_info *tinfo)
224 {
1. var_decl: Declaring variable tb without initializer.
225 struct nlattr *tb[IFLA_BRIDGE_VLAN_TUNNEL_MAX + 1];
226 u32 tun_id;
227 u16 vid, flags = 0;
228 int err;
229
230 memset(tinfo, 0, sizeof(*tinfo));
231
CID 1400055 (#1 of 1): Uninitialized pointer read (UNINIT)2.
uninit_use: Using uninitialized value tb[IFLA_BRIDGE_VLAN_TUNNEL_ID].
232 if (!tb[IFLA_BRIDGE_VLAN_TUNNEL_ID] ||
233 !tb[IFLA_BRIDGE_VLAN_TUNNEL_VID])
234 return -EINVAL;
