From baeeb9a8e1849975318e0abf90db5a3e255cad84 Mon Sep 17 00:00:00 2001 From: Fabian Pfitzner Date: Wed, 25 Jun 2025 10:39:14 +0200 Subject: [PATCH] bridge: dump mcast querier per vlan Dump the multicast querier state per vlan. This commit is almost identical to [1]. The querier state can be seen with: bridge -d vlan global The options for vlan filtering and vlan mcast snooping have to be enabled in order to see the output: ip link set [dev] type bridge mcast_vlan_snooping 1 vlan_filtering 1 The querier state shows the following information for IPv4 and IPv6 respectively: 1) The ip address of the current querier in the network. This could be ourselves or an external querier. 2) The port on which the querier was seen 3) Querier timeout in seconds [1] https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?id=16aa4494d7fc6543e5e92beb2ce01648b79f8fa2 Reviewed-by: Ido Schimmel Acked-by: Nikolay Aleksandrov Signed-off-by: Fabian Pfitzner Signed-off-by: David Ahern --- bridge/vlan.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/bridge/vlan.c b/bridge/vlan.c index 14b8475d..3c240207 100644 --- a/bridge/vlan.c +++ b/bridge/vlan.c @@ -852,6 +852,11 @@ static void print_vlan_global_opts(struct rtattr *a, int ifindex) print_uint(PRINT_ANY, "mcast_querier", "mcast_querier %u ", rta_getattr_u8(vattr)); } + if (vtb[BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE]) { + struct rtattr *attr = vtb[BRIDGE_VLANDB_GOPTS_MCAST_QUERIER_STATE]; + + bridge_print_mcast_querier_state(attr); + } if (vtb[BRIDGE_VLANDB_GOPTS_MCAST_IGMP_VERSION]) { vattr = vtb[BRIDGE_VLANDB_GOPTS_MCAST_IGMP_VERSION]; print_uint(PRINT_ANY, "mcast_igmp_version", -- 2.47.2
