Hi, Roopa, Two minor comments:
The parameter br is not used in the br_add_vlan_tunnel_info() method, it should be removed: +static int br_add_vlan_tunnel_info(struct net_bridge *br, + struct net_bridge_port *p, int cmd, + u16 vid, u32 tun_id) +{ + int err; + + switch (cmd) { + case RTM_SETLINK: + if (p) { + /* if the MASTER flag is set this will act on the global + * per-VLAN entry as well + */ + err = nbp_vlan_tunnel_info_add(p, vid, tun_id); + if (err) + break; + } else { + return -EINVAL; + } + + break; + + case RTM_DELLINK: + if (p) + nbp_vlan_tunnel_info_delete(p, vid); + else + return -EINVAL; + break; + } + + return 0; +} + The parameter br is used inside br_process_vlan_tunnel_info() only in the two Cases, when br_add_vlan_tunnel_info() is invoked. Since we saw earlier that it should be removed from br_add_vlan_tunnel_info(), it should also be removed from br_process_vlan_tunnel_info() as it is not needed anymore: +static int br_process_vlan_tunnel_info(struct net_bridge *br, + struct net_bridge_port *p, int cmd, + struct vtunnel_info *tinfo_curr, + struct vtunnel_info *tinfo_last) { + int t, v; + int err; + + if (tinfo_curr->flags & BRIDGE_VLAN_INFO_RANGE_BEGIN) { + if (tinfo_last->flags & BRIDGE_VLAN_INFO_RANGE_BEGIN) + return -EINVAL; + memcpy(tinfo_last, tinfo_curr, sizeof(struct vtunnel_info)); + } else if (tinfo_curr->flags & BRIDGE_VLAN_INFO_RANGE_END) { + if (!(tinfo_last->flags & BRIDGE_VLAN_INFO_RANGE_BEGIN)) + return -EINVAL; + if ((tinfo_curr->vid - tinfo_last->vid) != + (tinfo_curr->tunid - tinfo_last->tunid)) + return -EINVAL; + /* XXX: tun id and vlan id attrs must be same + */ + t = tinfo_last->tunid; + for (v = tinfo_last->vid; v <= tinfo_curr->vid; v++) { + err = br_add_vlan_tunnel_info(br, p, cmd, + v, t); + if (err) + return err; + t++; + } + memset(tinfo_last, 0, sizeof(struct vtunnel_info)); + memset(tinfo_curr, 0, sizeof(struct vtunnel_info)); + } else { + err = br_add_vlan_tunnel_info(br, p, cmd, + tinfo_curr->vid, + tinfo_curr->tunid); + if (err) + return err; + } + + return 0; +} + Regards, Rami Rosen
