2006-05-12[bgpd] CID #7, remove useless NULL check, bgp_static_update_mainPaul Jakma
2006-05-12 Paul Jakma <paul.jakma@sun.com> * bgp_route.c: (bgp_static_update_main) Remove useless NULL check, code already assumes bgp_static can not be NULL, fixes CID #7.
2006-05-08[bgpd] Bug #240, Fix route-server crash when static routes are configuredPaul Jakma
2006-05-08 Paul Jakma <paul.jakma@sun.com> * bgp_route.c: (bgp_afi_node_get) given table should never be NULL, check/assert this. (bgp_static_update) Bug #240. Rsclients should only be passed the static update if they are configured for the afi,safi.
2006-05-04[bgpd] Fix bug where FSM can stay hung forever in Idle/ClrngPaul Jakma
2006-05-04 Paul Jakma <paul.jakma@sun.com> * bgp_route.c: (general) Fix logical bug in clearing, noted by Chris Caputo in [quagga-users 6728] - clearing depended on at least one route being added to workqueue, in order for workqueue completion function to restart FSM. However, if no routes are cleared, then the completion function never is called, it needs to be called manually if the workqueue didn't get scheduled. Finally, clearing is per-peer-session, not per AFI/SAFI, so the FSM synchronisation should be in bgp_clear_route_table. (bgp_clear_route_table) Wrong place for FSM/clearing synchronisation, move to.. (bgp_clear_route) FSM/clearing synchronisation should be here. If no routes were cleared, no workqueue scheduled, call the completion func to ensure FSM kicks off again.
2006-03-06[bgpd] Start off FSM again once clearing finishes.Paul Jakma
2006-03-03 Paul Jakma <paul.jakma@sun.com> * bgp_route.c: (bgp_clear_node_complete) Doh. When clearing is complete we need to kick off FSM again.
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.
2006-02-18[bgpd] trivial readability fixPaul Jakma
2006-02-18 Paul Jakma <paul.jakma@sun.com> * bgp_route.c: (bgp_announce_check) trivial, move declaration of two local variables into the only block where they are used, to aid the reader.
2006-02-05[bgpd] Fix peer prefix counts and make it slightly more robustpaul
2006-02-05 Paul Jakma <paul.jakma@sun.com> * bgp_route.h: Add BGP_INFO_COUNTED to track whether prefix has been counted or not. * bgp_route.c: (bgp_pcount_{inc,dec}rement) new helpers, to centralise inc/dec of prefix-count, (bgp_rib_remove) Remove pcount decrement, use helper. (bgp_rib_withdraw) ditto, additionally use previous function too. (bgp_update_main) Use pcount helpers. (bgp_clear_route_node) ditto, aslo REMOVED routes don't need clearing.
2006-02-02[lib/workqueue] remove the useless 'delay' factor.paul
2006-02-02 Paul Jakma <paul.jakma@sun.com> * workqueue.h: (struct work_queue) Remove the delay field. It served no purpose and just introduced bad behaviour. Should be excised before its allowed to escape into 1.0. This removes need for the 'flood' and runs_since_clear fields. * workqueue.c: (general) excise delay factor between queue runs, hence the 'flood' crap too.. See above. * bgp_route.c: (bgp_{clear_node,process}_queue_init) delay field is removed from workqueue spec.
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.
2005-11-142005-11-14 Paul Jakma <paul.jakma@sun.com>paul
* zebra_rib.c: (rib_process) convert to new workqueue specs and shut up gcc, which complains about cast from void via function parameters, for some dumb reason. Do the cast inside the function instead. (rib_queue_qnode_del) ditto. (rib_queue_init) no need for the casts anymore.
2005-09-102005-09-10 Paul Jakma <paul.jakma@sun.com>paul
* Makefile.am: bgpd shouldn't list libgp's sources as its own. Use LDADD. * bgp_aspath.h: (struct assegment) New struct, abstract representation of a list of AS_PATH segments and the contained ASNs. (struct aspath) Remove the raw-data related fields, reference the abstract struct assegment instead. Remove several other computed fields, it's just a headache to maintain them and they're cheap to compute from struct assegment. (aspath_parse) parse a stream, not a pointer to raw data. (aspath_count_{hops,confeds,size}) helpers to access information formerly directly contained in struct aspath. (aspath_snmp_pathseg) Helper for SNMP, BGP MIB wants to be able to output hex representation of raw data. * bgp_aspath.c: (general) partial-rewrite. Store aspath data as an abstract singly-linked list of abstract segments, rather than storing the raw data, and parsing it each and every time. Remove several count/size fields which are cheap to compute from the abstract segment structure. (global) Include stream.h, needed for aspath_parse, and others. Couple of helper macros added. (struct assegment_header) Just the header, and only the header. (assegment_data_{new,free}) convenience functions for AS_SEG_DATA allocation, the dynamic, per-segment array of ASNs. (assegment_{new,free,free_all,dup,dup_all}) convenience functions for creating struct assegments. The _all forms will follow the entire chain of segments from the given segment. (assegment_prepend_asns) new function, prepend an ASN N times to segment. (assegment_append_asns) Append a list (array) of ASNs to segment. (int_cmp) convenience function for the aspath hash. (assegment_normalise) new function. Normalise the given segment chain to meet expectations of Quagga, and to eliminate differing raw representations of the same paths. Merge 'runs' of SEQUENCEs into one segment as our internal segment is not limited by the protocol AS_PATH segment length. Sort ASNs in SETs. (aspath_new) Take void argument to quell warnings. Use the assegment convenience functions. (assegment_count_{asns,confeds,hops}) new functions to compute at runtime values previously held in struct aspath. (aspath_size) ditto. (aspath_make_str_count) rewritten to stringify new representation, and to be slightly easier to understand hopefully. (aspath_str_update) convenience function, update the aspath str. Should investigate removing maintained string from struct aspath, just run-time compute it, as per other fields. It's just a maintenance headache, would save noticeable amount of RAM with possibly not much extra run-time cost. (aspath_dup) use the assegment dup functions. (aspath_hash_alloc) Take void * argument to satisfy gcc. Use the proper helper functions to dup data. (assegments_parse) new function. parse raw AS_PATH data into struct assegments. Normalise and return the head of the list. (aspath_parse) Parse a stream, not pointer to raw data and use assegments_parse to do it. (assegment_data_put) Write out a single segment data in protocol form to stream. (assegment_header_put) ditto but for segment header. (aspath_put) new function. As per previous but for an entire struct aspath. (aspath_snmp_pathseg) wrapper around aspath_put for bgp_snmp.c. Uses a static buffer sadly. (aspath_aggregate_as_set_add) rewritten to use assegments. (aspath_aggregate) ditto (aspath_{firstas,loop,private_as}_check) ditto (aspath_{merge,prepend,add_one_as}) ditto (aspath_cmp_left{_confed}) ditto (aspath_delete_confed_seq) ditto, plus fixed to properly delete all leading confed segments. (aspath_as_add) Just use assegment_append_asns. (aspath_segment_add) updated to use assegments. (enum as_token) Add values for confeds (aspath_gettoken) Add support for confeds (aspath_str2aspath) ditto (aspath_key_make) updated to use as_segments. Also, add segment type into the hash value as appropriate. (aspath_cmp) updated to use as_segments. (aspath_print) don't segfault on NULL argument. * bgp_attr.c: (bgp_attr_aspath) aspath_parse wants the stream now. No need for manual forwarding of stream. (bgp_packet_attribute) empty aspath is now denoted by NULL segment field, length is gone. Use aspath_size() to determine size. (bgp_attr_init) Fix declaration, explicitely specify void arg. (bgp_dump_routes_attr) Use aspath_size() to determine size. * bgp_route.c: (bgp_info_cmp) use the aspath_count_* functions. (bgp_rib_withdraw) remove unused variable. Use aspath_count_hops. * bgp_snmp.c: (bgp4PathAttrTable) raw data is gone, use aspath_snmp_pathseg to get the representation.
2005-08-26 * bgp_route.c: Third (?) attempt to fix best selection breakagehasso
introduced long time ago with route server patch. Hopefully it's last case to fix - route-server client not in peer group. [backport candidate]
2005-08-222005-08-22 Paul Jakma <paul.jakma@sun.com>paul
* 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.
2005-06-282005-06-28 Paul Jakma <paul.jakma@sun.com>paul
* (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.
2005-06-012005-06-01 Paul Jakma <paul.jakma@sun.com>paul

(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_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.

* (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.

* vty.h: Remove fields in struct vty that were related to VTY_CONTINUE capabilities (that were used only in bgpd/bgp_route.c and are now removed). Also remove some other fields that were not being used at all. * vty.c: (vty_execute) Do not test for obsolete status values VTY_START and VTY_CONTINUE. (vty_read) Remove calls to vty->output_func since that was part of the VTY_CONTINUE infrastructure that has been removed. (vty_flush) Remove code to support VTY_START and VTY_CONTINUE. (vty_close) Remove code to cancel vty->t_output thread, since that thread was never actually used. * bgp_route.c: Remove all code related to VTY_CONTINUE; this feature is deprecated because the output did not represent a single point in time. All output needs to be generated inline and buffered by the library code. (route_vty_out,route_vty_out_tag,damp_route_vty_out, flap_route_vty_out) Remove code to count number of lines of output, since this was only useful for VTY_CONTINUE behavior. (bgp_show_callback) Removed. (bgp_show_table) Remove hooks for VTY_CONTINUE callback support. As a result, there's a new output_arg argument to this function. Make function static. (bgp_show) Make function static and add a new output_arg argument. Change all functions that call bgp_show or bgp_show_table to pass the new output_arg argument (that used to be passed inside vty->output_arg). * bgp_mplsvpn.c: Remove declarations of functions defined in bgp_route.c; these declarations belong in bgp_route.h. * bgp_route.h: Declare 3 global functions used in both bgp_route.c and in bgp_mplsvpn.c.

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.
