* 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

* bgp_network.c: (bgp_accept) use XSTRDUP * bgpd.c: (peer_delete) XFREE the correct memtype, not free. (peer_create) use XSTRDUP * bgp_packet.c: (bgp_stream_dup) deleted, stream_dup should be used (various) update -> s/bgp_stream_dup/stream_dup
2005-04-072005-04-07 Paul Jakma <paul.jakma@sun.com>paul
* (global): Fix up list loops to match changes in lib/linklist, and some basic auditing of usage. * configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES * HACKING: Add notes about deprecating interfaces and commands. * lib/linklist.h: Add usage comments. Rename getdata macro to listgetdata. Rename nextnode to listnextnode and fix its odd behaviour to be less dangerous. Make listgetdata macro assert node is not null, NULL list entries should be bug condition. ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use with for loop, Suggested by Jim Carlson of Sun. Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the "safety" of previous macro. LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to distinguish from the similarly named functions, and reflect their effect better. Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section with the old defines which were modified above, for backwards compatibility - guarded to prevent Quagga using it.. * lib/linklist.c: fix up for linklist.h changes. * ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single scan of the area list, rather than scanning all areas first for INTER_ROUTER and then again for INTER_NETWORK. According to 16.2, the scan should be area specific anyway, and further ospf6d does not seem to implement 16.3 anyway.

* (global) Update code to match stream.h changes. stream_get_putp effectively replaced with stream_get_endp. stream_forward renamed to stream_forward_getp. stream_forward_endp introduced to replace some previous setting/manual twiddling of putp by daemons. * lib/stream.h: Remove putp. Update reference to putp with endp. Add stream_forward_endp, which daemons were doing manually. Rename stream_forward to stream_forward_getp. lib/stream.c: Remove/update references to putp. introduce stream_forward_endp.
2005-02-02 * bgp_fsm.c, bgp_open.c, bgp_packet.c, bgp_route.[ch], bgp_vty.c,hasso
bgpd.[ch]: Add BGP_INFO_STALE flag and end-of-rib support. "bgp graceful-restart" commands added. Show numbers of individual messages in "show ip bgp neighbor" command. Final pieces of graceful restart. [merge from GNU Zebra]
2005-02-01 * bgp_open.c, bgp_packet.c, bgp_vty.c, bgpd.[ch]: Remove "no neighborhasso
capability route-refresh" commands. Route refresh capability is sent anyway now. Preserve dummy deprecated commands. [merge from GNU Zebra]
2005-02-01 * bgp_nexthop.c: Improve debug.hasso
* bgpd.[ch], bgp_nexthop.c, bgp_snmp.c: Remove useless bgp_get_master() function. * bgp_packet.c: MP AFI_IP update and withdraw parsing. * bgp_fsm.c: Reset peer synctime in bgp_stop(). bgp_fsm_change_status() is better place to log about peer status change than bgp_event(). Log in bgp_connect_success(). * bgp_vty.c: Fix typo in comment. * bgp_attr.c: Better log about unknown attribute. [merge from GNU Zebra]
2005-01-052005-01-05 Paul Jakma <paul@dishone.st>paul
* bgp_packet.c: (bgp_write) set socket to nonblock while writing this should be generalised. See bugzilla #102. Fix supplied by wawa@yandex-team.ru (Vladimir Ivanov).

* *.c: Change level of debug messages to LOG_DEBUG.
2004-11-202004-11-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* global: Replace strerror with safe_strerror. And vtysh/vtysh.c needs to include "log.h" to pick up the declaration.
2004-10-132004-10-13 Paul Jakma <paul@dishone.st>paul
* (global) more const'ification and fixups of types to clean up code. * bgp_mplsvpn.{c,h}: (str2tag) fix abuse. Still not perfect, should use something like the VTY_GET_INTEGER macro, but without the vty_out bits.. * bgp_routemap.c: (set_aggregator_as) use VTY_GET_INTEGER_RANGE (no_set_aggregator_as) ditto. * bgpd.c: (peer_uptime) fix unlikely bug, where no buffer is returned, add comments about troublesome return value.
