Issue 1: 1. Enable pim on an interface. 2. Configure query-interval or query max response time, which results in pimd crash. Root cause: 1. When pim is enabled on an interface, it creates a igmp socket with querier_timer and other_querier time as NULL. 2. When query-interval/max_response_time is configured, it call the function igmp_sock_query_reschedule() to reshedule the query. This function check either of querier_timer or other_querier timer should be running. Since in this case both are NULL, it results in crash. Issue 2: 1. Enable pim on an interface. 2. Execute no ip igmp query-interval or query max response time, which results in pimd crash. Root cause: 1. When pim is enabled on an interface, it creates a pim interface with querier_timer and other_querier time as NULL. 2. When no ip igmp query-interval/max_response_time is executed, it will check either of querier_timer or other_querier timer should be running. Since in this case both are NULL, it results in crash. Fix: When pim is enabled on an interface, it creates a igmp socket with mtrace_only as true. So add a check if mtrace_only is true, then don't reshedule the query.
