2009-07-28bgpd: start listener on first instanceStephen Hemminger
Start BGP listener only after first instance is started. This helps the security if BGP is not used but daemon is started. It also addresses some issues like MD5 not working on listener unless IPV6 configured (because listener was not in list); as well as compiler warnings. * bgp_network.c: (bgp_listener) listen socket creation consolidated here (bgp_socket) Use bgp_listener * bgpd.c: (bgp_get) call bgp_socket on creation of first struct bgp. (bgp_init) remove bgp_socket call. * memtypes.c: Add MTYPE_BGP_LISTENER
2008-07-21[bgpd] TCP-MD5: password vty configuration and initial Linux supportPaul Jakma
2008-07-21 Paul Jakma <paul.jakma@sun.com> * bgp_packet.c: (bgp_open_receive) fix warning in a zlog call * bgp_vty.c: (bgp_vty_return) add return code * bgpd.c: (bgp_master_init) setup the socket list. * bgp_network.c: Remove the dual IPv4/6 socket thing for now, which was implemented by Michael, until such time as its clear its required for Linux (see sockopt comments). IPv6 support, including IPv4 sessions on AF_INET6 sockets, therefore is broken, and the '-l 0.0.0.0' arguments would need to be given to bgpd to make things work here. 2008-07-21 Michael H. Warfield <mhw@wittsend.com> YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Tomohiko Kusuda <kusuda@inetcore.com> Leigh Brown <leigh@solinno.co.uk> * bgp_network.c: (bgp_md5_set_one) shim between libzebra tcp-md5 sockopt and bgpd. (bgp_md5_set_socket) Helper for bgp_connect (bgp_md5_set) setup TCP-MD5SIG for the given peer. (bgp_connect) call out to bgp_md5_set_socket for the outgoing connect socket. (bgp_socket) save references to the listen sockets, needed if TCP-MD5SIG is applied later or changed. * bgp_vty.c: (*neighbor_password_cmd) New 'neighbor ... password' commands. * bgpd.c: (peer_{new,delete) manage TCP-MD5 password (peer_group2peer_config_copy) inherit TCP-MD5 password (peer_password_{un,}set) orchestrate the whole add/remove of TCP-MD5 passwords: applying checks, stopping peers, and trying to return errors to UI, etc. (bgp_config_write_peer) save password. Fix missing newline in writeout of neighbor ... port. 2008-07-21 Paul Jakma <paul.jakma@sun.com> * sockunion.c: ifdef out various places that converted v4mapped sockets to pure v4. Doesn't seem necessary at all, presumably a workaround for now historical inet_ntop bugs (?) 2008-07-21 Michael H. Warfield <mhw@wittsend.com> YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> * sockopt.{c,h}: (sockopt_tcp_signature) Add TCP-MD5SIG support.
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
2006-03-30[bgpd] trivial: use a distinct memtype for struct bgp_synchronizePaul Jakma
2006-03-19 Paul Jakma <paul.jakma@sun.com> * memtypes.c: Add MTYPE_BGP_SYNCHRONISE. * bgp_advertise.c: Use a distinct memory type for struct bgp_synchronize.

2005-10-182005-10-18 Paul Jakma <paul.jakma@sun.com>paul
* (general) SPF memory management cleanup and fix for rare double-free bug. * ospf_spf.h: (struct vertex_parent) New struct to hold parent specific data, eg the backlink and the parent vertex pointer, and point to the appropriate general struct vertex_nexthop. (struct vertex_nexthop) remove parent vertex pointer, so this struct can be shared across vertices. (struct vertex) rename list child to list children. Remove list of nexthops, replace with list of vertex_parents. * ospf_spf.c: (update_stat) trivial, remove cast from void *. (vertex_nexthop_new) remove init of parent - field is gone from struct vertex_nexthop. (ospf_canonical_nexthops_free) Remove the canonical vertex_nexthop memory objects. These are the vertex_nexthops attached to the first level of router vertices from the root. (vertex_parent_new) new function, create a vertex_parent. (vertex_parent_free) ditto, but free it. (ospf_vertex_new) Update to match changes to struct vertex. (ospf_vertex_free) Recursively free a struct vertex and its children. The parent list is used as a reference count. vertex_nexthops must be free seperately, if required. (ospf_vertex_dump) update to match struct vertex changes. Print out backlink of parents too. (ospf_vertex_add_parent) ditto. (ospf_lsa_has_link) update comment. (ospf_nexthop_add_unique) removed, not needed anymore. (ospf_nexthop_merge) ditto. (ospf_spf_consider_nexthop) renamed to ospf_spf_add_parent. Simplified to just create vertex_parent and add it. (ospf_spf_flush_parents) new function, flush out the parent list. (ospf_nexthop_calculation) Take the relevant route_lsa_link as an argument, which simplifies things and removes the need for the hack in ospf_nexthop_add_unique - ospf_spf_next already knew exactly which link the cost calculated was for. Update to match struct vertex changes too. (ospf_spf_next) Don't create a vertex for W unnecessarily, if it's there's a vertex already created for W, use it, and hence there's no need to free it either. Update some manipulation/comparisons of distance to match. Flush the parent list if a lower cost path is found. (ospf_spf_route_free) unused, removed. (ospf_spf_dump) match the struct vertex changes, and dump the ifname if possible. (ospf_spf_calculate) At end of SPF, free the canonical nexthops and call ospf_vertex_free on the root vertex to free the entire tree. * ospf_interface.c: (ospf_vl_set_params) match struct vertex changes. * ospf_route.c: (ospf_intra_route_add) ditto (ospf_route_copy_nexthops_from_vertex) ditto * memtypes.c: (memory_list_ospf) Add MTYPE_OSPF_VERTEX_PARENT.

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_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.
