2008-07-22[bgpd] Fix triggerable crash when compiled with --disable-bgp-announcePaul Jakma
2008-07-22 Paul Jakma <paul.jakma@sun.com> * HACKING: Document preference for compiler conditional code, over cpp conditional. * configure.ac: DISABLE_BGP_ANNOUNCE always should be defined. * bgp_{packet,route,advertise}.c: change to compiler testing of DISABLE_BGP_ANNOUNCE, rather than cpp. 2008-07-22 MIYAJIMA Mitsuharu <miyajima.mitsuharu@anchor.jp> * bgp_packet.c: (bgp_update_packet_eor) Fix crash triggerable if a bgpd was compiled with --disable-bgp-announce and if GR is advertised by peer.
2007-04-29[bgpd] Fix warnings: hash callbacks should match hash API declarationsPaul Jakma
2007-04-22 Sebastien Tandel <sebastien@tandel.be> * bgp_advertise.c : (baa_hash_alloc, baa_hash_key, baa_hash_cmp) conforms to quagga hash API. Defines _hash_[alloc|key|cmp] with void * arguments as defined by the API. * bgp_aspath.c,h : (aspath_key_make) conforms to quagga hash API. Defines _hash_[alloc|key|cmp] with void * arguments as defined by the API. * bgp_attr.c,h : (cluster_hash_alloc, cluster_hash_key_make, cluster_hash_cmp, transit_hash_alloc, transit_hash_key_make, transit_hash_cmp, attrhash_key_make, attrhash_cmp, bgp_attr_hash_alloc) conforms to quagga hash API. Defines _hash_[alloc|key|cmp] with void * arguments as defined by the API.
2006-08-27[bgpd] fix mtype in XFREE and NULL out freed pointerPaul Jakma
2006-08-27 Paul Jakma <paul.jakma@sun.com> * bgp_advertise.c: (bgp_sync_delete) fix mtype in XFREE. NULL out peer->hash after free, to be sure.
2006-03-30[bgpd] trivial: use a distinct memtype for struct bgp_synchronizePaul Jakma
2006-03-19 Paul Jakma <paul.jakma@sun.com> * memtypes.c: Add MTYPE_BGP_SYNCHRONISE. * bgp_advertise.c: Use a distinct memory type for struct bgp_synchronize.

* (global) The great bgpd extern and static'ification. * bgp_routemap.c: remove unused ROUTE_MATCH_ASPATH_OLD code (route_set_metric_compile) fix u_int32_t to ULONG_MAX comparison warnings. * bgp_route.h: (bgp_process, bgp_withdraw, bgp_update) export these used by various files which had their own private declarations, in the case of mplsvpn - incorrect.

* bgpd/(general) refcount struct peer and bgp_info, hence allowing us add work_queues for bgp_process. * bgpd/bgp_route.h: (struct bgp_info) Add 'lock' field for refcount. Add bgp_info_{lock,unlock} helper functions. Add bgp_info_{add,delete} helpers, to remove need for users managing locking/freeing of bgp_info and bgp_node's. * bgpd/bgp_table.h: (struct bgp_node) Add a flags field, and BGP_NODE_PROCESS_SCHEDULED to merge redundant processing of nodes. * bgpd/bgp_fsm.h: Make the ON/OFF/ADD/REMOVE macros lock and unlock peer reference as appropriate. * bgpd/bgp_damp.c: Remove its internal prototypes for bgp_info_delete/free. Just use bgp_info_delete. * bgpd/bgpd.h: (struct bgp_master) Add work_queue pointers. (struct peer) Add reference count 'lock' (peer_lock,peer_unlock) New helpers to take/release reference on struct peer. * bgpd/bgp_advertise.c: (general) Add peer and bgp_info refcounting and balance how references are taken and released. (bgp_advertise_free) release bgp_info reference, if appropriate (bgp_adj_out_free) unlock peer (bgp_advertise_clean) leave the adv references alone, or else call bgp_advertise_free cant unlock them. (bgp_adj_out_set) lock the peer on new adj's, leave the reference alone otherwise. lock the new bgp_info reference. (bgp_adj_in_set) lock the peer reference (bgp_adj_in_remove) and unlock it here (bgp_sync_delete) make hash_free on peer conditional, just in case. * bgpd/bgp_fsm.c: (general) document that the timers depend on bgp_event to release a peer reference. (bgp_fsm_change_status) moved up the file, unchanged. (bgp_stop) Decrement peer lock as many times as cancel_event canceled - shouldnt be needed but just in case. stream_fifo_clean of obuf made conditional, just in case. (bgp_event) always unlock the peer, regardless of return value of bgp_fsm_change_status. * bgpd/bgp_packet.c: (general) change several bgp_stop's to BGP_EVENT's. (bgp_read) Add a mysterious extra peer_unlock for ACCEPT_PEERs along with a comment on it. * bgpd/bgp_route.c: (general) Add refcounting of bgp_info, cleanup some of the resource management around bgp_info. Refcount peer. Add workqueues for bgp_process and clear_table. (bgp_info_new) make static (bgp_info_free) Ditto, and unlock the peer reference. (bgp_info_lock,bgp_info_unlock) new exported functions (bgp_info_add) Add a bgp_info to a bgp_node in correct fashion, taking care of reference counts. (bgp_info_delete) do the opposite of bgp_info_add. (bgp_process_rsclient) Converted into a work_queue work function. (bgp_process_main) ditto. (bgp_processq_del) process work queue item deconstructor (bgp_process_queue_init) process work queue init (bgp_process) call init function if required, set up queue item and add to queue, rather than calling process functions directly. (bgp_rib_remove) let bgp_info_delete manage bgp_info refcounts (bgp_rib_withdraw) ditto (bgp_update_rsclient) let bgp_info_add manage refcounts (bgp_update_main) ditto (bgp_clear_route_node) clear_node_queue work function, does per-node aspects of what bgp_clear_route_table did previously (bgp_clear_node_queue_del) clear_node_queue item delete function (bgp_clear_node_complete) clear_node_queue completion function, it unplugs the process queues, which have to be blocked while clear_node_queue is being processed to prevent a race. (bgp_clear_node_queue_init) init function for clear_node_queue work queues (bgp_clear_route_table) Sets up items onto a workqueue now, rather than clearing each node directly. Plugs both process queues to avoid potential race. (bgp_static_withdraw_rsclient) let bgp_info_{add,delete} manage bgp_info refcounts. (bgp_static_update_rsclient) ditto (bgp_static_update_main) ditto (bgp_static_update_vpnv4) ditto, remove unneeded cast. (bgp_static_withdraw) see bgp_static_withdraw_rsclient (bgp_static_withdraw_vpnv4) ditto (bgp_aggregate_{route,add,delete}) ditto (bgp_redistribute_{add,delete,withdraw}) ditto * bgpd/bgp_vty.c: (peer_rsclient_set_vty) lock rsclient list peer reference (peer_rsclient_unset_vty) ditto, but unlock same reference * bgpd/bgpd.c: (peer_free) handle frees of info to be kept for lifetime of struct peer. (peer_lock,peer_unlock) peer refcount helpers (peer_new) add initial refcounts (peer_create,peer_create_accept) lock peer as appropriate (peer_delete) unlock as appropriate, move out some free's to peer_free. (peer_group_bind,peer_group_unbind) peer refcounting as appropriate. (bgp_create) check CALLOC return value. (bgp_terminate) free workqueues too. * lib/memtypes.c: Add MTYPE_BGP_PROCESS_QUEUE and MTYPE_BGP_CLEAR_NODE_QUEUE
