From d8e8016594f87bbdd3bbb1737a95c39c6e951ede Mon Sep 17 00:00:00 2001 From: paul Date: Fri, 4 May 2007 20:15:47 +0000 Subject: [bgpd] Trim memory usage of BGP routes 2007-05-03 Paul Jakma * bgp_route.h: (struct info) Move less frequently used fields to a lazily allocated struct info_extra. Export bgp_info_extra_get * bgp_route.c: (bgp_info_extra_new) allocate extra (bgp_info_extra_free) Free damp info and the info_extra. (bgp_info_extra_get) Retrieve the info_extra of a struct info, allocating as required. (generally) adjust to use info->extra * bgp_damp.c: (generally) use bgp_info_extra_get to access dampinfo * bgp_attr.h: Move rarely allocated attributes from struct attr to a struct attr_extra, for a substantial saving in size of struct attr. * bgp_attr.c: (bgp_attr_extra_{new,free}), new, self-explanatory. (bgp_attr_extra_get) Get the attr_extra for a given struct attr, allocating it if needs be. (bgp_attr_dup) Shallow copy the struct attr and its attr_extra. (generally) adjust to know about attr->extra. * bgp_debug.c: (bgp_dump_attr) ditto * bgp_vty.c: (show_bgp_memory) print attr and info extra sizes. * bgp_nexthop.c: (generally) adjust to know about attr->extra and info->extra. * bgp_{packet,routemap,snmp,zebra}.c: ditto * lib/memtypes.c: Add MTYPE_ATTR_EXTRA and MTYPE_BGP_ROUTE_EXTRA --- lib/memtypes.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'lib/memtypes.c') diff --git a/lib/memtypes.c b/lib/memtypes.c index 902eedcb..f1b10e71 100644 --- a/lib/memtypes.c +++ b/lib/memtypes.c @@ -96,6 +96,7 @@ struct memory_list memory_list_bgp[] = { MTYPE_PEER_GROUP, "Peer group" }, { MTYPE_PEER_DESC, "Peer description" }, { MTYPE_ATTR, "BGP attribute" }, + { MTYPE_ATTR_EXTRA, "BGP extra attributes" }, { MTYPE_AS_PATH, "BGP aspath" }, { MTYPE_AS_SEG, "BGP aspath seg" }, { MTYPE_AS_SEG_DATA, "BGP aspath segment data" }, @@ -104,6 +105,7 @@ struct memory_list memory_list_bgp[] = { MTYPE_BGP_TABLE, "BGP table" }, { MTYPE_BGP_NODE, "BGP node" }, { MTYPE_BGP_ROUTE, "BGP route" }, + { MTYPE_BGP_ROUTE_EXTRA, "BGP ancillary route info" }, { MTYPE_BGP_STATIC, "BGP static" }, { MTYPE_BGP_ADVERTISE_ATTR, "BGP adv attr" }, { MTYPE_BGP_ADVERTISE, "BGP adv" }, -- cgit v1.2.3
