From afb226bebd8350f8f6523f4692658b944bc2997f Mon Sep 17 00:00:00 2001 From: Paul Jakma Date: Tue, 21 Feb 2006 01:09:01 +0000 Subject: [bgpd] Record afi/safi in bgp_table. Serialise peer clear with FSM. 2006-02-21 Paul Jakma * bgpd.h: move the clear_node_queue to be peer specific. Add a new peer status flag, PEER_STATUS_CLEARING. * bgp_table.h: (struct bgp_table) Add fields to record afi, safi of the table. (bgp_table_init) Take afi and safi to create table for. * bgp_table.c: (bgp_table_init) record the afi and safi. * bgp_nexthop.c: Update all calls to bgp_table_init. * bgp_vty.c: ditto. * bgpd.c: ditto. * bgp_fsm.c: (bgp_timer_set) dont bring up a session which is clearing. * bgp_route.c: (general) Update all bgp_table_init calls. (bgp_process_{rsclient,main}) clear_node is serialised via PEER_STATUS_CLEARING and fsm now. (struct bgp_clear_node_queue) can be removed. struct bgp_node can be the queue item data directly, as struct peer can be kept in the new wq global user data and afi/safi can be retrieved via bgp_node -> bgp_table. (bgp_clear_route_node) fix to get peer via wq->spec.data, afi/safi via bgp_node->bgp_table. (bgp_clear_node_queue_del) no more item data to delete, only unlock the bgp_node. (bgp_clear_node_complete) only need to unset CLEARING flag and unlock struct peer. (bgp_clear_node_queue_init) queue attaches to struct peer now. record peer name as queue name. (bgp_clear_route_table) If queue transitions to active, serialise clearing by setting PEER_STATUS_CLEARING rather than plugging process queue, and lock peer while queue active. Update to pass only bgp_node as per-queue-item specific data. --- bgpd/bgp_table.h | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'bgpd/bgp_table.h') diff --git a/bgpd/bgp_table.h b/bgpd/bgp_table.h index d7c8272b..e13022bb 100644 --- a/bgpd/bgp_table.h +++ b/bgpd/bgp_table.h @@ -30,7 +30,11 @@ typedef enum struct bgp_table { bgp_table_t type; - + + /* afi/safi of this table */ + afi_t afi; + safi_t safi; + /* The owner of this 'bgp_table' structure. */ void *owner; @@ -63,7 +67,7 @@ struct bgp_node #define BGP_NODE_PROCESS_SCHEDULED (1 << 0) }; -extern struct bgp_table *bgp_table_init (void); +extern struct bgp_table *bgp_table_init (afi_t, safi_t); extern void bgp_table_finish (struct bgp_table *); extern void bgp_unlock_node (struct bgp_node *node); extern void bgp_node_delete (struct bgp_node *node); -- cgit v1.2.1
