* [bgpd] Record afi/safi in bgp_table. Serialise peer clear with FSM.paul2006-02-211-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2006-02-21 Paul Jakma <paul.jakma@sun.com> * 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] remove export of long defunct functionpaul2006-01-101-1/+0

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bgp_route.h: (struct bgp_info) add a new flag, BGP_INFO_REMOVED. BGP_INFO_VALID is already overloaded, don't care to do same thing to STALE or HISTORY. * bgpd.h: (BGP_INFO_HOLDDOWN) Add INFO_REMOVED to the macro, as a route which should generally be ignored. * bgp_route.c: (bgp_info_delete) Just set the REMOVE flag, rather than doing actual work, so that bgp_process (called directly, or indirectly via the scanner) can catch withdrawn routes. (bgp_info_reap) Actually remove the route, what bgp_info_delete used to do, only for use by bgp_process. (bgp_best_selection) reap any REMOVED routes, other than the old selected route. (bgp_process_rsclient) reap the old-selected route, if appropriate (bgp_process_main) ditto (bgp_rib_withdraw, bgp_rib_remove) make them more consistent with each other. Don't play games with the VALID flag, bgp_process is async now, so it didn't make a difference anyway. Remove the 'force' argument from bgp_rib_withdraw, withdraw+force is equivalent to bgp_rib_remove. Update all its callers. (bgp_update_rsclient) bgp_rib_withdraw and force set is same as bgp_rib_remove. (route_vty_short_status_out) new helper to print the leading route-status string used in many command outputs. Consolidate. (route_vty_out, route_vty_out_tag, damp_route_vty_out, flap_route_vty_out) use route_vty_short_status_out rather than duplicate. (route_vty_out_detail) print state of REMOVED flag. (BGP_SHOW_SCODE_HEADER) update for Removed flag.

| | | | | | | | | | * (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.

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.

(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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (at Technical University of Madrid as part of Euro6ix Project) Enhanced Route Server functionality and Route-Maps: * bgpd/bgpd.h: Modified 'struct peer' and 'struct bgp_filter' to support rs-clients. A 'struct bgp_table *rib' has been added to the first (to mantain a separated RIB for each rs-client) and two new route-maps have been added to the last (for import/export policies). Added the following #defines: RMAP_{IN|OUT|IMPORT|EXPORT|MAX}, PEER_RMAP_TYPE_{IMPORT|EXPORT} and BGP_CLEAR_SOFT_RSCLIENT. * bgpd/bgpd.c: Modified the functions that create/delete/etc peers in order to consider the new fields included in 'struct peer' for supporting rs-clients, i.e. the import/export route-maps and the 'struct bgp_table'. * bgpd/bgp_route.{ch}: Modified several functions related with receiving/sending announces in order to support the new Route Server capabilities. Function 'bgp_process' has been reorganized, creating an auxiliar function for best path selection ('bgp_best_selection'). Modified 'bgp_show' and 'bgp_show_route' for displaying information about any RIB (and not only the main bgp RIB). Added commands for displaying information about RS-clients RIBs: 'show bgp rsclient (A.B.C.D|X:X::X:X)', 'show bgp rsclient (A.B.C.D|X:X::X:X) X:X::X:X/M', etc * bgpd/bgp_table.{ch}: The structure 'struct bgp_table' now has two new fields: type (which can take the values BGP_TABLE_{MAIN|RSCLIENT}) and 'void *owner' which points to 'struct bgp' or 'struct peer' which owns the table. When creating a new bgp_table by default 'type=BGP_TABLE_MAIN' is set. * bgpd/bgp_vty.c: The commands 'neighbor ... route-server-client' and 'no neighbor ... route-server-client' now not only set/unset the flag PEER_FLAG_RSERVER_CLIENT, but they create/destroy the 'struct bgp_table' of the peer. Special actions are taken for peer_groups. Command 'neighbor ... route-map WORD (in|out)' now also supports two new kinds of route-map: 'import' and 'export'. Added commands 'clear bgp * rsclient', etc. These commands allow a new kind of soft_reconfig which affects only the RIB of the specified RS-client. Added commands 'show bgp rsclient summary', etc which display a summary of the rs-clients configured for the corresponding address family. * bgpd/bgp_routemap.c: A new match statement is available, 'match peer (A.B.C.D|X:X::X:X)'. This statement can only be used in import/export route-maps, and it matches when the peer who announces (when used in an import route-map) or is going to receive (when used in an export route-map) the route is the same than the one specified in the statement. For peer-groups the statement matches if the specified peer is member of the peer-group. A special version of the command, 'match peer local', matches with routes originated by the Route Server (defined with 'network ...', redistributed routes and default-originate). * lib/routemap.{ch}: Added a new clause 'call NAME' for use in route-maps. It jumps into the specified route-map and when it returns the first route-map ends if the called RM returns DENY_MATCH, or continues in other case.

* [zebra 18626] move zebra socket paths to configure.acpaul2003-04-071-1/+0
| | | | | | | | | | | moved definition of the various socket paths from the per daemon header files into configure.ac. it will set the paths to be in the directory specified by --localstatedir=<prefix> or otherwise will try to guess as best it can ( a la pid file path detection - which probably should try reference ${prefix} too). the present hardcoded socket path, /tmp, isnt really correct. should be in /var somewhere really.
