2009-06-02[snmp] Compiler warning fixes for when "--enable-snmp" is configured.Chris Caputo
Compiled on 32-bit and 64-bit linux gcc 4.1.2 platforms. No run-time testing on 32-bit and limited run-time testing on 64-bit.
2008-08-25Make --enable-snmp cross compile and make libcrypto optional with ↵Joakim Tjernlund
--without-crypto Autoconfig work by me, the rest was done by "Kirill K. Smirnov" <lich@math.spbu.ru>
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

* 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.

* (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.
2005-02-01 * bgp_attr.c, bgp_snmp.c, bgp_vty.c, bgpd.[ch]: Remove support for oldhasso
draft - ie. "neighbor version 4-" commands. Preserve dummy "neighbor version" command as deprecated. [merge from GNU Zebra]
2005-02-01 * bgp_nexthop.c: Improve debug.hasso
* bgpd.[ch], bgp_nexthop.c, bgp_snmp.c: Remove useless bgp_get_master() function. * bgp_packet.c: MP AFI_IP update and withdraw parsing. * bgp_fsm.c: Reset peer synctime in bgp_stop(). bgp_fsm_change_status() is better place to log about peer status change than bgp_event(). Log in bgp_connect_success(). * bgp_vty.c: Fix typo in comment. * bgp_attr.c: Better log about unknown attribute. [merge from GNU Zebra]
2004-10-13Make initializing smux connection configurable - "smux peer OID" commandhasso
initializes connection, and "no smux peer" command terminates it. Fixes bugzilla #47 and #112.

* (global) more const'ification and fixups of types to clean up code. * bgp_mplsvpn.{c,h}: (str2tag) fix abuse. Still not perfect, should use something like the VTY_GET_INTEGER macro, but without the vty_out bits.. * bgp_routemap.c: (set_aggregator_as) use VTY_GET_INTEGER_RANGE (no_set_aggregator_as) ditto. * bgpd.c: (peer_uptime) fix unlikely bug, where no buffer is returned, add comments about troublesome return value.
