Add output for the mcast_active_v4 and mcast_active_v6 states. If their output is 1 then IGMP/MLD snooping is applied to multicast payload traffic of their according protocol family. This is the case when:
* the bridge interface is up * multicast snooping is enabled * an IGMP/MLD querier is present * for own IPv6 MLD querier: an IPv6 address is configured on the bridge Signed-off-by: Linus Lüssing <[email protected]> --- bridge/vlan.c | 10 ++++++++++ include/uapi/linux/if_bridge.h | 2 ++ include/uapi/linux/if_link.h | 2 ++ ip/iplink_bridge.c | 12 ++++++++++++ 4 files changed, 26 insertions(+) diff --git a/bridge/vlan.c b/bridge/vlan.c index 3c240207028b..d0b6afdee49d 100644 --- a/bridge/vlan.c +++ b/bridge/vlan.c @@ -920,6 +920,16 @@ static void print_vlan_global_opts(struct rtattr *a, int ifindex) print_uint(PRINT_ANY, "msti", "msti %u ", rta_getattr_u16(vattr)); } + if (vtb[BRIDGE_VLANDB_GOPTS_MCAST_ACTIVE_V4]) { + vattr = vtb[BRIDGE_VLANDB_GOPTS_MCAST_ACTIVE_V4]; + print_uint(PRINT_ANY, "mcast_active_v4", "mcast_active_v4 %u ", + rta_getattr_u8(vattr)); + } + if (vtb[BRIDGE_VLANDB_GOPTS_MCAST_ACTIVE_V6]) { + vattr = vtb[BRIDGE_VLANDB_GOPTS_MCAST_ACTIVE_V6]; + print_uint(PRINT_ANY, "mcast_active_v6", "mcast_active_v6 %u ", + rta_getattr_u8(vattr)); + } print_nl(); if (vtb[BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS]) { vattr = RTA_DATA(vtb[BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS]); diff --git a/include/uapi/linux/if_bridge.h b/include/uapi/linux/if_bridge.h index 4d7509c4b84d..be0935057c56 100644 --- a/include/uapi/linux/if_bridge.h +++ b/include/uapi/linux/if_bridge.h @@ -584,6 +584,8 @@ enum { BRIDGE_VLANDB_GOPTS_MCAST_ROUTER_PORTS, BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE, BRIDGE_VLANDB_GOPTS_MSTI, + BRIDGE_VLANDB_GOPTS_MCAST_ACTIVE_V4, + BRIDGE_VLANDB_GOPTS_MCAST_ACTIVE_V6, __BRIDGE_VLANDB_GOPTS_MAX }; #define BRIDGE_VLANDB_GOPTS_MAX (__BRIDGE_VLANDB_GOPTS_MAX - 1) diff --git a/include/uapi/linux/if_link.h b/include/uapi/linux/if_link.h index d05f5cc750ff..7d36cfd6b30c 100644 --- a/include/uapi/linux/if_link.h +++ b/include/uapi/linux/if_link.h @@ -794,6 +794,8 @@ enum { IFLA_BR_MCAST_QUERIER_STATE, IFLA_BR_FDB_N_LEARNED, IFLA_BR_FDB_MAX_LEARNED, + IFLA_BR_MCAST_ACTIVE_V4, + IFLA_BR_MCAST_ACTIVE_V6, __IFLA_BR_MAX, }; diff --git a/ip/iplink_bridge.c b/ip/iplink_bridge.c index df3264c3f45d..b3c0d6bb5310 100644 --- a/ip/iplink_bridge.c +++ b/ip/iplink_bridge.c @@ -784,6 +784,18 @@ static void bridge_print_opt(struct link_util *lu, FILE *f, struct rtattr *tb[]) "mcast_mld_version %u ", rta_getattr_u8(tb[IFLA_BR_MCAST_MLD_VERSION])); + if (tb[IFLA_BR_MCAST_ACTIVE_V4]) + print_uint(PRINT_ANY, + "mcast_active_v4", + "mcast_active_v4 %u ", + rta_getattr_u8(tb[IFLA_BR_MCAST_ACTIVE_V4])); + + if (tb[IFLA_BR_MCAST_ACTIVE_V6]) + print_uint(PRINT_ANY, + "mcast_active_v6", + "mcast_active_v6 %u ", + rta_getattr_u8(tb[IFLA_BR_MCAST_ACTIVE_V6])); + if (tb[IFLA_BR_NF_CALL_IPTABLES]) print_uint(PRINT_ANY, "nf_call_iptables", -- 2.51.0
