2007-08-06[bgpd] cleanup, compact and consolidate capability parsing codePaul Jakma
2007-07-26 Paul Jakma <paul.jakma@sun.com> * (general) Clean up and compact capability parsing slightly. Consolidate validation of length and logging of generic TLV, and memcpy of capability data, thus removing such from cap specifc code (not always present or correct). * bgp_open.h: Add structures for the generic capability TLV header and for the data formats of the various specific capabilities we support. Hence remove the badly named, or else misdefined, struct capability. * bgp_open.c: (bgp_capability_vty_out) Use struct capability_mp_data. Do the length checks *before* memcpy()'ing based on that length (stored capability - should have been validated anyway on input, but..). (bgp_afi_safi_valid_indices) new function to validate (afi,safi) which is about to be used as index into arrays, consolidates several instances of same, at least one of which appeared to be incomplete.. (bgp_capability_mp) Much condensed. (bgp_capability_orf_entry) New, process one ORF entry (bgp_capability_orf) Condensed. Fixed to process all ORF entries. (bgp_capability_restart) Condensed, and fixed to use a cap-specific type, rather than abusing capability_mp. (struct message capcode_str) added to aid generic logging. (size_t cap_minsizes[]) added to aid generic validation of capability length field. (bgp_capability_parse) Generic logging and validation of TLV consolidated here. Code compacted as much as possible. * bgp_packet.c: (bgp_open_receive) Capability parsers now use streams, so no more need here to manually fudge the input stream getp. (bgp_capability_msg_parse) use struct capability_mp_data. Validate lengths /before/ memcpy. Use bgp_afi_safi_valid_indices. (bgp_capability_receive) Exported for use by test harness. * bgp_vty.c: (bgp_show_summary) fix conversion warning (bgp_show_peer) ditto * bgp_debug.h: Fix storage 'extern' after type 'const'. * lib/log.c: (mes_lookup) warning about code not being in same-number array slot should be debug, not warning. E.g. BGP has several discontigious number spaces, allocating from different parts of a space is not uncommon (e.g. IANA assigned versus vendor-assigned code points in some number space).
2007-05-04[bgpd] Trim memory usage of BGP routesPaul Jakma
2007-05-03 Paul Jakma <paul.jakma@sun.com> * 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
2006-09-14[bgpd] Fix 0.99 shutdown regression, introduce Clearing and Deleted statesPaul Jakma
2006-09-14 Paul Jakma <paul.jakma@sun.com> * (general) Fix some niggly issues around 'shutdown' and clearing by adding a Clearing FSM wait-state and a hidden 'Deleted' FSM state, to allow deleted peers to 'cool off' and hit 0 references. This introduces a slow memory leak of struct peer, however that's more a testament to the fragility of the reference counting than a bug in this patch, cleanup of reference counting to fix this is to follow. * bgpd.h: Add Clearing, Deleted states and Clearing_Completed and event. * bgp_debug.c: (bgp_status_msg[]) Add strings for Clearing and Deleted. * bgp_fsm.h: Don't allow timer/event threads to set anything for Deleted peers. * bgp_fsm.c: (bgp_timer_set) Add Clearing and Deleted. Deleted needs to stop everything. (bgp_stop) Remove explicit fsm_change_status call, the general framework handles the transition. (bgp_start) Log a warning if a start is attempted on a peer that should stay down, trying to start a peer. (struct .. FSM) Add Clearing_Completed events, has little influence except when in state Clearing to signal wait-state can end. Add Clearing and Deleted states, former is a wait-state, latter is a placeholder state to allow peers to disappear quietly once refcounts settle. (bgp_event) Try reduce verbosity of FSM state-change debug, changes to same state are not interesting (Established->Established) Allow NULL action functions in FSM. * bgp_packet.c: (bgp_write) Use FSM events, rather than trying to twiddle directly with FSM state behind the back of FSM. (bgp_write_notify) ditto. (bgp_read) Remove the vague ACCEPT_PEER peer_unlock, or else this patch crashes, now it leaks instead. * bgp_route.c: (bgp_clear_node_complete) Clearing_Completed event, to end clearing. (bgp_clear_route) See extensive comments. * bgpd.c: (peer_free) should only be called while in Deleted, peer refcounting controls when peer_free is called. bgp_sync_delete should be here, not in peer_delete. (peer_delete) Initiate delete. Transition to Deleted state manually. When removing peer from indices that provide visibility of it, take great care to be idempotent wrt the reference counting of struct peer through those indices. Use bgp_timer_set, rather than replicating. Call to bgp_sync_delete isn't appropriate here, sync can be referenced while shutting down and finishing deletion. (peer_group_bind) Take care to be idempotent wrt list references indexing peers.
2006-05-23[bgpd] expand vty help for neighbor ... update-sourcePaul Jakma
2006-05-23 Paul Jakma <paul.jakma@sun.com> * bgp_vty.c: (neighbor_update_source_cmd) Expand tab completion to make it clear it takes both address and ifname.
2006-03-30[bgpd] Add 'show bgp memory' for stats on fixed-size allocations in bgpdPaul Jakma
2006-03-19 Paul Jakma <paul.jakma@sun.com> * bgpd/bgp_vty.c: Add includes to get several structs we want to provide usage statistics on. (show_bgp_memory_cmd) Show memory usage stats for various notable fixed size objects. Using mtype_stats_alloc and mtype_memstr recently added to memory.c. (bgp_show_summary) Report some additional stats specific to the given BGP instance and/or AFI/SAFI such as table counts, peers, rsclients and peer-groups. (bgp_vty_init) Install show_bgp_memory_cmd.
2006-02-21[bgpd] Add Clrng description to bgp summary state.Paul Jakma
2006-02-21 Paul Jakma <paul.jakma@sun.com> * bgp_vty.c: (bgp_show_summary) Add a 'Clrng' sub-description to state of peer while it's suppressed due to clearing.
2006-02-21[bgpd] Record afi/safi in bgp_table. Serialise peer clear with FSM.Paul Jakma
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.
2006-01-19[compiler] miscellaneous trivial compiler warning fixespaul
2006-01-19 Paul Jakma <paul.jakma@sun.com> * (general) various miscellaneous compiler warning fixes. Remove redundant break statements from switch clauses which return. return from main, not exit, cause it annoys SOS. Remove stray semi-colons which cause empty-statement warnings. * zebra/main.c: (sighup) remove private declaration of external function.
2005-10-012005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* zebra.h: Declare new functions zebra_route_string() and zebra_route_char(). * log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New functions to map zebra route numbers to strings. * zebra_vty.c: (route_type_str) Remove obsolete function: use new library function zebra_route_string() instead. Note that there are a few differences: for IPv6 routes, we now get "ripng" and "ospf6" instead of the old behavior ("rip" and "ospf"). (route_type_char) Remove obsolete function: ues new library function zebra_route_char() instead. Note that there is one difference: the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route, whereas the new one returns 'X'. (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace route_type_str() with zebra_route_string(). (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char() with zebra_route_char(). * bgp_vty.c: (bgp_config_write_redistribute) Use new library function zebra_route_string instead of a local hard-coded table. * ospf6_asbr.c: Remove local hard-coded tables zroute_name and zroute_abname. Change the ZROUTE_NAME macro to use new library function zebra_route_string(). Remove the ZROUTE_ABNAME macro. (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with a call to zebra_route_char(), and be sure to fix the format string, since we now have a char instead of a char *. * ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and zebra_route_abname. Note that the zebra_route_name[] table contained mixed-case strings, whereas the zebra_route_string() function returns lower-case strings. (ospf6_zebra_read_ipv6): Change debug message to use new library function zebra_route_string() instead of zebra_route_name[]. (show_zebra): Use new library function zebra_route_string() instead of zebra_route_name[]. * ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto. (ospf_redist_string) New function implemented using new library function zebra_route_string(). Note that there are a few differences in the output that will result: the new function returns strings that are lower-case, whereas the old table was mixed case. Also, the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the new function returns "ospf6". * ospfd.h: Remove extern struct message ospf_redistributed_proto[], and add extern const char *ospf_redist_string(u_int route_type) instead. * ospf_asbr.c: (ospf_external_info_add) In two messages, use ospf_redist_string instead of LOOKUP(ospf_redistributed_proto). * ospf_vty.c: Remove local hard-coded table distribute_str. (config_write_ospf_redistribute,config_write_ospf_distribute): Use new library function zebra_route_string() instead of distribute_str[]. * ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset, ospf_redistribute_default_set,ospf_redistribute_check) In debug messages, use ospf_redist_string() instead of LOOKUP(ospf_redistributed_proto). * rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded table str[]. Replace str[] with calls to new library function zebra_route_string(). * ripd.c: Remove local hard-coded table route_info[]. (show_ip_rip) Replace uses of str[] with calls to new library functions zebra_route_char and zebra_route_string. * ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded table str[]. Replace str[i] with new library function zebra_route_string(i). * ripngd.c: Remove local hard-coded table route_info[]. (show_ipv6_ripng) Use new library function zebra_route_char() instead of table route_info[].

(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.

(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.

* (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.

2004-09-132004-09-13 Jose Luis Rubio <jrubio@dit.upm.es>paul
(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.

* Better 'show bgp' support for views (eg ipv6), see [quagga-dev 238] * bgpd/bgp_route.c: (bgp_show) Take a struct bgp argument instead of view string. (bgp_show_neighbor_route) Take a struct peer argument instead of ip string. (peer_adj_routes) ditto (show_adj_routes) ditto (peer_lookup_in_view) new function to return appropriate struct peer for a given view string. (misc) Fixup all calls to above to reflect new calling arguments, and use peer_lookup_in_view as needed. Additional commands installed to use expanded functionality above, existing commands modified to suit as well. * bgpd/bgp_vty.c: 2 new aliases.
