Modified files:
mld6igmp xrl_mld6igmp_node.cc
Log message:
* Change the action for processing COMMAND_FAILED XRL error
within method :mld6igmp_client_send_add_delete_membership_cb()
from XLOG_FATAL() to print an error and continue with the
processing.
This is to avoid the following race condition:
If the MFEA is shutdown before MLD/IGMP and PIM,
then we may have both MLD/IGMP and PIM shutting down at the same time.
During that shutdown period, if MLD/IGMP sends delete_membership
XRL to PIM, PIM may return COMMAND_FAILED if it is in process of
deregistering with MLD/IGMP.
* Add a check to XrlMld6igmpNode::proto_send() whether the MFEA
is alive, and return immediately if it is dead.
This upfront check is an optimization so we can avoid an unnecessary
XRL, and we can print a better error message.
