Hello Steve,
I need some information regarding the following code snippet in
totemnet.c file.
817 if (instance->netif_bind_state == BIND_STATE_REGULAR) {
818 if (instance->netif_state_report &
NETIF_STATE_REPORT_UP) {
819 log_printf (instance->totemnet_log_level_notice,
820 "The network interface [%s] is now up.\n",
821 totemip_print
(&instance->totem_interface->boundto));
822 instance->netif_state_report =
NETIF_STATE_REPORT_DOWN;
823 instance->totemnet_iface_change_fn
(instance->context, &instance->my_id);
824 }
825 /*
826 * Add a timer to check for interface going down in
single membership
827 */
828 if (instance->my_memb_entries == 1) {
829 poll_timer_add (instance->totemnet_poll_handle,
830 instance->totem_config->downcheck_timeout,
831 (void *)instance,
832 timer_function_netif_check_timeout,
833 &instance->timer_netif_check_timeout);
834 }
835
836 } else {
837 if (instance->netif_state_report &
NETIF_STATE_REPORT_DOWN) {
838 log_printf (instance->totemnet_log_level_notice,
839 "The network interface is down.\n");
840 instance->totemnet_iface_change_fn
(instance->context, &instance->my_id);
841 }
842 instance->netif_state_report = NETIF_STATE_REPORT_UP;
843
844 }
The above code snippet is very confusing as I dont find much comments
for the same. Also I dont find the usage of netif_state_report parameter
anywhere else in the code.
Could you please explain me what exactly does this code do and what is
the purpose of the netif_state_report parameter?
Regards,
Shridhar.
