  "message": "zebra: add structure to hold per-prefix state in RIB\n\nAdd the rib_dest_t structure to hold per-prefix state in the routing\ninformation base. This gives us an appropriate place to maintain the\nqueueing state of a route_node. Queuing state was previously being\nstored on the first rib in the list of ribs hanging off the\nroute_node.\n\n  * zebra/rib.h\n\n    - Add new structure rib_dest_t.\n\n    - Remove the rn_status field from \u0027struct rib\u0027, it is no longer\n      required.\n\n    - Add macros (RNODE_FOREACH_RIB, RNODE_FOREACH_RIB_SAFE) for\n      walking all \u0027struct ribs\u0027 corresponding to a route_node. These\n      hide the fact that there is an intermediate rib_dest_t\n      structure.\n\n    - Add a few utility inlines to go between a rib_dest_t and\n      associated structures.\n\n  * zebra/zebra_rib.c\n\n    - rib_link()/rib_unlink()\n\n      Tweak for new behavior, where the \u0027info\u0027 pointer of a route_node\n      points to a rib_dest_t. The list of ribs for a prefix now hangs\n      off of the dest.\n\n      Change the way we ref count route_nodes. We now hold a single\n      ref count on a route_node if there is a corresponding\n      rib_dest_t.\n\n    - Maintain the queuing state of a route_node on the flags field of\n      the rib_dest_t.\n\n    - Add the rib_gc_dest() function, which deletes a rib_dest_t if it\n      is no longer required. A rib_dest_t can be deleted iff there are\n      no struct ribs hanging off of it.\n\n    - Call rib_gc_dest() any time we unlink a rib from the\n      rib_dest_t. Currently we only need to call it once, just before\n      we return from rib_process().\n\n  * zebra/{redistribute,zebra_rib,zebra_snmp,zebra_vty}.c\n\n    Use new macros to walk over route_node ribs.\n\n  * lib/memtypes.c\n\n    Add memory type for rib_dest_t.\n\nSigned-off-by: Avneesh Sachdev \u003cavneesh@opensourcerouting.org\u003e\nSigned-off-by: David Lamparter \u003cequinox@opensourcerouting.org\u003e\n",
