* 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.

* bgp_vty.c: (bgp_vty_init) gcc 4 compile fix. static function declarations shouldn't be inside functions. * bgp_dump.c: (bgp_dump_interval_add) ditto.
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 Hugo Santos <hsantos@av.it.pt>paul
* bgp_vty.c: (general) Add support for BGP IPv6 Multicast SAFI commands and BGP_IPV6M_NODE.
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.
2005-08-03 * bgp_routemap.c: Revert part of leaking communities fix commited inhasso
2005-05-27. While ecommunity fix seems to be correct, community case isn't. Fixes bugzilla #209. [backport candidate]
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.
2005-06-152005-06-15 Paul Jakma <paul.jakma@sun.com>paul
* bgpd.c: (bgp_terminate) workqueue's are lazy allocated and its possible to terminate bgpd before workqueues were setup, causing an abort/crash. Reported by Ashish Mehta of Sun.
2005-06-012005-06-01 Paul Jakma <paul.jakma@sun.com>paul
* 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.

(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.

Implement non-blocking zclient I/O with buffering. * zclient.h (struct zclient): Add two fields to support non-blocking I/O: struct buffer *wb, and struct thread *t_write. (zclient_free): Remove function. (zebra_redistribute_send): Change 2nd arg from socket fd to struct zclient * (needed to support non-blocking I/O and buffering). (zclient_send_message): New function to send an arbitrary message with non-blocking I/O. * zclient.c (zclient_new): Create write buffer. (zclient_free): Remove unused function. (zclient_stop): Must cancel new t_write thread. Also, reset all buffers: ibuf, obuf, and wb. (zclient_failed): New helper function for typical error handling. (zclient_flush_data): New thread to flush queued data. (zclient_send_message): New function to send the message in zclient->obuf to zebra using non-blocking I/O and buffering. (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use new zclient_send_message function instead of calling writen. (zclient_start): Set socket non-blocking. Also, change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. (zebra_redistribute_send): Change 2nd arg to struct zclient *. Can now use zclient->obuf to assemble the message instead of allocating a temporary stream. And call zclient_send_message to send the message instead of writen. (zclient_read): Convert to support non-blocking I/O by using stream_read_try instead of deprecated stream_read. (zclient_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. * rip_zebra.c (rip_redistribute_set, rip_redistribute_unset, rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset): The 2nd arg to zebra_redistribute_send is now zclient instead of zclient->sock. * isis_zebra.h (isis_zebra_finish): Remove declaration of unused function. * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message to send the message to zebra instead of calling writen directly, since zclient_send_message understands non-blocking I/O and will manage the buffer queue appropriately. (isis_zebra_finish): Remove unused function, particularly since the zclient_free function has been removed.
2005-04-09 * bgp_vty.c: Make "exit-address-family" work in IPv4 unicast addresshasso
family node. [backport candidate]
2005-04-08 * bgpd.texi: Document new "bgp bestpath as-path confed" command.hasso
* bgp_aspath.[ch], bgp_route.c, bgp_vty.c, bgpd.[ch]: Allow to enable the length of confederation path segments to be included during the as-path length check in the best path decision.
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.

Fix problems when netlink interfaces are renamed (same ifindex used for a new interface). Start cleaning up some problems with the way interface names are handled. * interface.c: (if_new_intern_ifindex) Remove obsolete function. (if_delete_update) After distributing the interface deletion message, set ifp->ifindex to IFINDEX_INTERNAL. (if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is IFINDEX_INTERNAL. (zebra_interface) Check return code from interface_cmd.func. Do not set internal ifindex values to if_new_intern_ifindex(), since we now use IFINDEX_INTERNAL for all pseudo interfaces. * kernel_socket.c: (ifm_read) Fix code and comments to reflect that all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL. * rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex. Detects interface rename events by checking if that ifindex is already being used. If it is, delete the old interface before assigning the ifindex to the new interface. (netlink_interface, netlink_link_change) Call set_ifindex to update the ifindex. * if.h: Remove define for IFINDEX_INTERNBASE and add define IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo- interfaces should have ifindex set to 0. (if_new) Remove function. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (ifname2ifindex) New function. * if.c: (if_new) Remove function (absorb into if_create). (if_create) Replace function if_new with call to calloc. Set ifp->ifindex to IFINDEX_INTERNAL. Fix off-by-one error in assert to check length of interface name. Add error message if interface with this name already exists. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (if_delete) Implement with help of if_delete_retain. (ifindex2ifname) Reimplement using if_lookup_by_index. (ifname2ifindex) New function to complement ifindex2ifname. (interface) The interface command should check the name length and fail with a warning message if it is too long. (no_interface) Fix spelling in warning message. (if_nametoindex) Reimplement using if_lookup_by_name. (if_indextoname, ifaddr_ipv4_lookup) Reimplement using if_lookup_by_index. * bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead of if_delete, since it is generally not safe to remove interface structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Tighten up code. * ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function was commented out. But this is not safe: we should at least update the ifindex when the interface is deleted. So the new version updates the interface status and sets ifp->ifindex to IFINDEX_INTERNAL. (ospf6_zebra_route_update) Use if_indextoname properly. * ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface flags to help with debugging. * ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Make function static. Tighten up code. * rip_interface.c: (rip_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * ripng_interface.c: (ripng_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL.

2005-01-17 * bgp_route.c: Clear peer's routing table regardless whether it'shasso
configured or not. Being not configured is even better reason to do it.

* 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).
2004-12-09Add comments with warnings obtained on NetBSD/i386. Both are due togdt
size_t being used for streams. Perhaps cast to unsigned long before printf? Surely that's big enough even if size_t could be larger in theory. (no changelog, since only comment changes)

* bgp_main.c: (main) The 2nd argument to openzlog has been removed. * isis_main.c: (main) The 2nd argument to openzlog has been removed. * ospf6_main.c: (main) The 2nd argument to openzlog has been removed. Note that stdout logging will no longer be enabled by default when not running as a daemon. * ospf_main.c: (main) The 2nd argument to openzlog has been removed. * rip_main.c: (main) The 2nd argument to openzlog has been removed. * ripng_main.c: (main) The 2nd argument to openzlog has been removed. * main.c: (main) The 2nd argument to openzlog has been removed. So stdout logging will no longer be enabled by default. * irdp_main.c: (irdp_finish) Reduce severity of shutdown message from LOG_WARNING to LOG_INFO. * vtysh.c: Make several functions static instead of global. Added several commands to support destination-specific logging levels. (vtysh_completion) This function is unused, so comment it out. * basic.texi: Document new logging features. Separate basic config commands from basic VTY commands. * log.h: Replace struct zlog flags and maskpri fields with maxlvl array to support individual logging levels for each destination. Remove the 2nd argument to openzlog since the default logging config should be standardized inside the library. Replaced the zlog_set_flag and zlog_reset_flag functions with zlog_set_level. And zlog_set_file now requires an additional log_level argument. Declare zlog_proto_names for use inside command.c in the "show logging" command. Added defines useful for command construction. * log.c: (vzlog) Decide where to send the message based on the individual logging levels configured for each destination. Remove support for ZLOG_STDERR since it was never actually used. Support record-priority for terminal monitors. (zlog_signal,zlog_backtrace_sigsafe) Support destination-specific logging levels. Remove stderr support (was never used). Added support for terminal monitor logging. (_zlog_assert_failed) Increase message severity to LOG_EMERG. (openzlog) Remove 2nd argument since default config should be standardized in library. By default, terminal monitoring is set to debug, and all other logging is disabled. (zlog_set_flag,zlog_reset_flag) Removed. (zlog_set_level) New function to replace zlog_set_flag and zlog_reset_flag. Supports destination-specific logging levels. (zlog_set_file,zlog_reset_file) Support file-specific logging level. (zlog_rotate) Log an error message if fopen fails, and support new file-specific logging level. * command.h: Change DEFUN_CMD_FUNC_DECL and DEFUN_CMD_FUNC_TEXT so that command functions will be static instead of global. Remove declarations for config_exit and config_help. Define new macros DEFUNSH_ATTR, DEFUNSH_HIDDEN, and DEFUNSH_DEPRECATED so we can have deprecated commands in vtysh. Similarly, for completeness, define macros ALIAS_SH, ALIAS_SH_HIDDEN, and ALIAS_SH_DEPRECATED. Also, fix bug in ALIAS_ATTR macro (didn't matter because it was never used). * command.c: Make many functions static instead of global. (facility_name,facility_match,level_match) New functions to support enhanced destination-specific logging levels. (config_write_host) Support new destination-specific logging levels. (config_logmsg) Added new "logmsg" command to help test logging system. (show_logging) Added "show logging" command to show the current configuration of the logging system. (config_log_stdout_level) Support explicit stdout logging level. (no_config_log_stdout) Now takes optional LEVEL arg. (config_log_monitor,config_log_monitor_level,no_config_log_monitor) New commands creating new "log monitor" commands to set terminal monitoring log level. (config_log_file_level) Support explicit file logging level. (config_log_syslog_level) Support explicit syslog logging level. (config_log_facility,no_config_log_facility) Implement new "log facility" command. (cmd_init) Add hooks for new commands: "show logging", "logmsg", "log stdout <level>", "log monitor", "log monitor <level>", "no log monitor", "log file <filename> <level>", "no log file <filename> <level>", "log syslog <level>", "log facility", and "no log facility". * vty.h: Added a "level" argument to vty_log so it can support "log record-priority". Declare new function vty_log_fixed for use in signal handlers. * vty.c: (vty_log,vty_log_out) Added a "level" argument to support "log record-priority" for vty terminal monitors. (vty_down_level) Use config_exit_cmd.func instead of calling config_exit directly (since command functions will now be static instead of global). (vty_log_fixed) New function to send terminal monitor messages from inside a signal handler.
