Tighten End-of-RIB detection -- now iff an MP_UNREACH is the *only* attribute and no ordinary update or withdraw. * added --socket/-z option -- sets zebra socket name * sets IPv6 tclass as required * improved next hop handling and added "show ip bgp scan" and "show ip bgpd scan detail" commands. see commits: fc98d16ea77372f4ab4231e8904f8467e8d1ef71 0e8032d69961ae196c11ba6ead856084c7acf7c2 b64bfc1c4a552fc0b4dd024d5f77171ec848a5df 318f0d8a7f5e8e87086bbf2a9e7c4b35638951ac 8e80bdf20f493a71bcf74262ed3aa3a2437f4df6 f04a80a5d209dbb54f6fec5d0149b7c0e489d29e * removed SAFI_UNICAST_MULTICAST * fiddled with SAFI_MPLS_LABELED_VPN -- unsure if this is now complete -- stuff here TODO ! * support for multicast SAFI see commits: 73bfe0bd9adb8e4dfcee7239e56a425c6d58f4e9 5a616c08ce089e25dc0e8da920727af4d11279bf * added "match probability" commands * uses "route_types.txt" more effectively -- which affects the implementation of "redistribute" commands see commit: e0ca5fde7be5b5ce90dae78c2477e8245aecb8e9 * "nexthop-local unchanged" included in configuration. zebra changes * some whitespace change clutter :-( * ZEBRA_HELLO and mopping up routes (BZ#448) * implement route_types.h * support for SAFI_MULTICAST commit f768f367bcd1f37a53c563495176a5a134caf234 IPv6 MP-BGP Routes addition and deletion commit cddf391bf6839e9f093cef15508669c1f3f92122 IPv4 MP-BGP Routes addition and deletion * brought up to date with RFC6275 * add --socket/-z option * add "ipv6 nd mtu <1-65535>" commands lib changes * filter-list handling -- does not free the filter-list before calling the delete_hook(). However, unlike commit 6a2e0f36b103386e57dbe3a6ee4716e809111198 *does* remove the filter-list from the name look-up, before calling the delete_hook() -- which I believe works better. * md5.c now includes RFC 2104 HMAC However fixed to remove compiler warning, by replacing use of caddr_t by unsigned char*. Some phantom whitespace changes elsewhere * prefix.c: commits d171bf58ef12ace43d48565e6870722dece1e6ed 051954f574b9c26458518a7029aeed118f0da620 9663386f16e6285a322747514527fdf1d19788e4 - optimise masklen2ip() and apply_mask_ipv4() -- the version here should work on a Big-Endian machine as well. - optimise ip_masklen() -- the version here should (a) work on a Big-Endian machine, (b) give the same result as before if the netmask is not, in fact, valid, and (c) uses just 256 bytes of table -- not 64K. Version here is probably not quite as fast as the previous patch... but certainly faster that what was there before. * zclient.c: introduced zclient_serv_path, for general zclient and for bgpd zlookup. Added ZEBRA_HELLO to client start. Added safi to ipv4 and ipv6 route add/delete.
| * ospfd: remove unused codeStephen Hemminger2011-12-071-55/+0
| | | | | | | | | | The code for nssa_range and other bits that were written but never used.
| * ospfd: remove useless RFC1583 checkAlexandre Chappuis2011-09-271-4/+0
| | | | | | | | | | | | | | | | | | | | * ospf_route.c: Function ospf_asbr_route_cmp is called uniquely from ospf_route_cmp() when the flag OSPF_RFC1583_COMPATIBLE is not set. Therefore, the check that the flag is set doesn't make sense at all and it can consequently be removed without doing any harm.

* | Removing compiler warnings.Chris Hall2010-04-161-1/+5
|/ | | | | | | | Removed nearly 100 compiler warnings in the various routing daemons which now clean compile. Removed one warning in vty.c, which was obscured by the other warnings. SO... this commit corrects the previous one.
* ospfd: Change struct ospf_path *oi to ifindex.Joakim Tjernlund2009-08-031-5/+6
| | | | | | * global: In struct ospf_path, change struct ospf_interface *oi to int ifindex. It is unsafe to reference *oi as an ospf interface can be deleted under your feet. Use a weak reference instead.
* [ospfd] compare ifIndex too when matching pathsJoakim Tjernlund2009-06-251-4/+11
| | | | | | ospf_path_lookup(), ospf_route_match_same() and ospf_ase_route_match_same() needs to compare if the interface matches too.
* [ospfd] Minor enhancements to recent self-host-routes suppression patchPaul Jakma2008-09-041-2/+16
| | | | | | | | | * ospf_spf.c: (ospf_spf_process_stubs) Track whether parent router vertex is the root, so that the host-route suppression logic need only be activated for such vertices. Move the actual logic to ospf_intra_add_stub. * ospf_route.c: (ospf_intra_add_stub) Main test of link moved here, notionally more appropriate.
* [ospfd] Bug #134, ospfd should be more robust to backward time changePaul Jakma2006-08-271-1/+1
| | | | | | | | | | | | | | 2006-08-25 Paul Jakma <paul.jakma@sun.com> * (general) Bug #134. Be more robust to backward time changes, use the newly added libzebra time functions. In most cases: recent_time -> recent_relative_time() gettimeofday -> quagga_gettime (QUAGGA_CLK_MONOTONIC, ..) time -> quagga_time. (ospf_make_md5_digest) time() call deliberately not changed. (ospf_external_lsa_refresh) remove useless gettimeofday, LSA tv_orig time was already set in ospf_lsa_new, called via ospf_external_lsa_new.
* [ospfd] CID #49, fix dereference before NULL checkPaul Jakma2006-05-121-1/+1
| | | | | | | 2006-05-11 Paul Jakma <paul.jakma@sun.com> * ospf_route.c: (ospf_route_delete_same_ext) Fix deref before NULL check by moving into check-protected block, fix CID #49.
* [ospfd] Fix SPF of virtual-linksPaul Jakma2006-05-041-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2006-04-24 Paul Jakma <paul.jakma@sun.com> * (general) More Virtual-link fixes, again with much help in testing / debug from Juergen Kammer. Primarily in SPF. * ospf_spf.h: Add guard. ospf_interface.h will include this header. * ospf_interface.h: Modify ospf_vl_lookup definition to take struct ospf as argument, so as to allow for NULL area argument. (struct ospf_vl_data) Remove out_oi, instead add a struct vertex_nexthop, to use as initial nexthop for backbone paths through a vlink. * ospf_interface.c: (ospf_vl_lookup) Modified to allow NULL area to be passed to indicate "any" (first) area. Add extra debug. (ospf_vl_set_params) vl_oi -> nexthop. Add extra debug. (ospf_vl_up_check) Fix debug, inet_ntoa returns a static buffer.. * ospf_route.c: (ospf_intra_add_router) Vlinks dont go through backbone, don't bother checking. * ospf_spf.c: (static struct list vertex_list) Record vertices that will need to be freed. (cmp) Order network before router vertices, as required, wasn't implemented. (vertex_nexthop_free) Mild additional robustness check. (vertex_parent_free) Take void argument, as this function is passed as list deconstructor for vertex parent list. (ospf_vertex_new) More debug. Set deconstructor for parent list. Track allocated vertices on the vertex_list. (ospf_vertex_free) Get rid of the tricky recursive cleanup of vertices. Now frees only the given vertex. (ospf_vertex_add_parent) Fix assert. (ospf_nexthop_calculation) Fix calculation of nexthop for VLink vertices, lookup the vl_data and use its previously recorded nexthop information. (ospf_spf_calculate) Vertices are freed simply by deleting vertex_list nodes and letting ospf_vertex_free as deconstructor work per-node. (ospf_spf_calculate_timer) Trivial optimisation, leave backbone SPF calculation till last to reduce SPF churn on VLink updates. * ospf_vty.c: (ospf_find_vl_data) update call to ospf_vl_lookup (no_ospf_area_vlink_cmd) ditto. (show_ip_ospf_interface_sub) For Vlinks, the peer address is more interesting than the output interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * (general) RFC3137 stub-router support * ospfd.h: Add OSPF_OUTPUT_COST_INFINITE define. (struct ospf_master) Add a OSPF_MASTER_SHUTDOWN flag for options, to allow shutdown to distinguish between complete shutdown and shutdown of a subset of ospf instances. (struct ospf) Add stub_router_{startup,shutdown_}time, configuration of startup and shutdown time for stub-router. Add t_graceful_shutdown struct thread, timer for graceful shutdown, if needed. (struct ospf_area) Add stub_router_state - run time state of stub-router for an area. Add flags for ADMIN, IS and WAS states. Add t_stub_router, timer thread to resend router-lsa for an area. * ospf_lsa.c: (ospf_link_cost) new simple function to spit out either the given lnks cost or infinite cost if stub-router is in effect. (lsa_link_{ptop,broadcast,virtuallink,ptomp}_set) use previous function for transit-links. (ospf_stub_router_timer) timer thread for end of startup stub router. Change state as required for the area and setup re-origination of router-lsa. (ospf_stub_router_check) Check/do whether stub-router should be enabled, and whether it requires timer to be setup. (ospf_router_lsa_new) call previous function at top. (ospf_router_lsa_originate) no external callers, made static. * ospf_lsa.h: (ospf_router_lsa_originate) removed. * ospf_main.c: (sigint) make static. remove call to exit, as ospf_terminate now deals with exiting. * ospf_route.c: (ospf_terminate) removed, now in ospfd.c. * ospf_vty.c: (show_ip_ospf_area) print out state of stub-router, if active. (show_ip_ospf) print out configuration of stub-router support, and details of graceful-shutdown if the timer is active. ((no)?ospf_max_metric_router_lsa_{admin,startup,shutdown}) new commands to (de-)?configure stub-router support. (config_write_stub_router) write out config of stub-router. (ospf_config_write) call previous. (ospf_vty_init) install the new stub-router commands. * ospfd.c: various functions made static. (ospf_new) Set defaults for stub-router. Graceful shutdown is made to default on, just to be adventerous. (ospf_graceful_shutdown_finish) new function, final part of shutdown. (ospf_graceful_shutdown_timer) timer thread wrapper for graceful-shutdown. (ospf_graceful_shutdown_check) check whether to setup timer for shutdown or proceed directly to final shutdown. (ospf_terminate) moved here from ospf_route.c, call ospf_finish for each instance. (ospf_finish) renamed to ospf_finish_final and made static. (ospf_finish) new function, exported wrapper around ospf_graceful_shutdown_check. (ospf_finish_final) complete shutdown of an instance. Add missing TIMER_OFF's of two timer threads. (ospf_area_free) opaque self lsa timer should be turned off.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * (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.

| | | | | | | | | | | | | | | | | | | | | | | * (general) extern and static qualifiers added. unspecified arguments in definitions fixed, typically they should be 'void'. function casts added for callbacks. Guards added to headers which lacked them. Proper headers included rather than relying on incomplete definitions. gcc noreturn function attribute where appropriate. * ospf_opaque.c: remove the private definition of ospf_lsa's ospf_lsa_refresh_delay. * ospf_lsa.h: export ospf_lsa_refresh_delay * ospf_packet.c: (ospf_make_md5_digest) make *auth_key const, correct thing to do - removes need for the casts later. * ospf_vty.c: Use vty.h's VTY_GET_INTEGER rather than ospf_vty's home-brewed versions, shuts up several warnings. * ospf_vty.h: remove VTY_GET_UINT32. VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX moved to lib/vty.h. * ospf_zebra.c: (ospf_distribute_list_update_timer) hacky overloading of the THREAD_ARG pointer should at least use uintptr_t.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * (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.
