2012-01-20zebra: include MTU option in RA on request (BZ#665)Denis Ovsienko
This implements a new "ipv6 nd mtu <1-65535>" interface-level command. * doc/ipv6.texi: add description * zebra/rtadv.c * rtadv_send_packet(): send option type 5, when configured * ipv6_nd_mtu(): new VTY helper * no_ipv6_nd_mtu(): ditto * rtadv_config_write(): add new option * rtadv_init(): list new helpers
2012-01-09bgpd: reinstate zlookup checks, required for BGP without zebraPaul Jakma
* bgp_nexthop.c: The nexthop lookup cache has to return success for queried nexthops if bgpd isn't connected to zebra, or else BGP without zebra doesn't work.
2012-01-08Marker merge for 'RE-0.99.17.6'Paul Jakma
This marker merge (i.e. an 'ours' strategy merge) is a placeholder to show that all commits in Quagga-RE stable, to its release RE-0.99.17.6 tag, have been reviewed and merged into 'master'.
2012-01-08bgpd: Fix incorrect attribute type code in call to bgp_attr_malformedPaul Jakma
2012-01-08bgpd: Improve flag error messages in bgp_attr_aspathPaul Jakma
* bgpd/bgp_attr.c: (bgp_attr_aspath) error message could be misleading, clearly log what flag was incorrect. (Problem noted in "bgpd: fix error message in bgp_attr_aspath()" in Quagga-RE)
2012-01-08lib: use prefix bit length macrosDenis Ovsienko
2012-01-08ospfd: use IS_LSA_SELF() where appropriateDenis Ovsienko
2012-01-08bgpd: rewrite attr flag error loggingDenis Ovsienko
* bgp_attr.c * attr_flag_str: new message list * bgp_attr_flags_diagnose(): new function, implements previously added error logging in a generic way * bgp_attr_origin(): use bgp_attr_flags_diagnose() * bgp_attr_nexthop(): ditto * bgp_attr_med(): ditto * bgp_attr_local_pref(): ditto * bgp_attr_atomic(): ditto * bgp_attr_originator_id(): ditto * bgp_attr_cluster_list(): ditto * bgp_mp_reach_parse(): ditto * bgp_mp_unreach_parse(): ditto
2012-01-08doc: "[no] router zebra" does not belong to ospfdDenis Ovsienko
2012-01-08ospfd: justify ospf_default_originate_timer()Denis Ovsienko
The function is implemented in ospf_lsa.c, move its "extern" declaration to ospf_lsa.h for consistency.
2012-01-08ospfd: address more trivial compiler warningsDenis Ovsienko
* ospf_ase.c * ospf_ase_complete_direct_routes(): dismiss unused variable
2012-01-08ospf6d: ospf6_lsa_cmd_init() does not existDenis Ovsienko
2012-01-08bgpd: improve "show ip bgp scan detail"Denis Ovsienko
* bgp_nexthop.c (show_ip_bgp_scan_tables): access proper structure field in AF_INET6 case, handle ifindex NH type properly
2012-01-08bgpd: dismiss some zlookup checksDenis Ovsienko
bgp_nexthop_onlink(): zlookup is not used here at all bgp_nexthop_lookup_ipv6(): rely on the detection performed by "query" function (this also changes the fallback value to 0), reorder if-block bgp_nexthop_lookup(): idem
2012-01-08bgpd: add "show ip bgp scan detail" commandDenis Ovsienko
* bgp_nexthop.c: (show_ip_bgp_scan) transform into show_ip_bgp_scan_tables(), which uses inet_ntop() and can dump nexthops on request; (show_ip_bgp_scan_detail_cmd) new function
2012-01-08bgpd: touch nexthop handling codeDenis Ovsienko
bgp_nexthop_lookup_ipv6(): declare variables where they are actually used, drop no-op initialization (the field is already 0) bgp_nexthop_lookup(): ditto bgp_nexthop_check_ebgp(): rename to bgp_nexthop_onlink() bgp_nexthop_cache_changed(): rename to bgp_nexthop_cache_different()
2012-01-06lib/if: trivial, fix rarely used if debug function to print everythingPaul Jakma
* if.c: (if_dump) loop that doesn't do anything, wants to be before the zlog of what it's meant to print out so all the connected addresses get printed out. Trival: just a debug function
2012-01-06general: remove inline qualifiers and move in-header functions to objectsPaul Jakma
* (general) Move functions in headers into files, to be compiled into shared object files. Remove inline qualifier from functions. Let the compiler do the work.

2012-01-02zebra: fix IPv6 RA wrt interface removal (BZ#480)Denis Ovsienko
2012-01-02zebra: fix ifindex test condition (BZ#487)Matthias Ferdinand
When the same ip address is used on several interfaces, and one of them gets deleted (or equivalent: set to down and then address removed), rib_delete_ipv[46] will also remove the connected route from other interfaces. rib_delete_ipv[46] is called twice when an interface is deleted: - for the "ifdown" event - for the address removal (note: this may be specific to the netlink interface of linux) The second call does not find the connected route to that same ifindex anymore, but deletes similar connected routes to any other ifindex instead. Reason: the ifindex check is on the same level as the check for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. If everything matches except for the ifindex, the "else" part (intended for different route types) is executed, thus removing the route from the wrong interface. fix: move ifindex check inside the "then" part of the check for ZEBRA_ROUTE_CONNECT/NEXTHOP_TYPE_IFINDEX. Now connected routes to other ifindexes will not spill over to the "else" part for different route types anymore.

* fix disagreement with C99 in zlog_debug calls Format specifier in some zlog_debug calls for size_t values was changed in order to C99 ('%u' -> '%zu'). * fix -Wsign-compare warnings Type of return value of ospf6_packet_max() was changed.

...otherwise 4294967295 is not a valid value on 32bit systems
2012-01-02ospf6d: Route locking (memory) cleanupTom Goff
* ospf6_route.c: (ospf6_route_best_next) Allows unlock route, even when there's no next route. This is consistent with how ospf6_route_next() behaves. * ospf6_intra.c: (ospf6_intra_prefix_lsa_remove) Make sure the last route considered is always unlocked. This is needed when the for loop terminates because ospf6_route_is_prefix() returns zero. Signed-off-by: Vyacheslav Trushkin <me@dogonthesun.net>
2012-01-02ospf6d: Have ospf6d cleanup when it terminates normallyTom Goff
A clean exit makes it easier to use memory debuggers. * ospf6_asbr.c: (ospf6_asbr_terminate) Add a function to do route map cleanup. * ospf6_lsa.c: (ospf6_lsa_terminate) Add a function to cleanup the lsa handler vector. * ospf6_main.c: (ospf6_exit) Add an function that causes ospf6d to gracefully exit. * ospf6_message.c: (ospf6_message_terminate) Add a function that frees the send and receive buffers. * ospf6_top.c: (ospf6_delete) Enable the ospf6_delete() function. Disable ospf6 before freeing everything. Signed-off-by: Vyacheslav Trushkin <me@dogonthesun.net> Conflicts: ospf6d/ospf6_lsa.h
2012-01-02lib: Add a function to delete all interfacesTom Goff
if.c: (if_terminate) This adds a cleanup function that can be called when a daemon exits, similar to vty_terminate().

2012-01-02ospfd: fix bug in NSSA ABR status checkDenis Ovsienko
* ospf_abr.c * ospf_abr_nssa_am_elected(): feed "best" instead of "address of best" into IPV4_ADDR_CMP(), because "best" is a pointer; also, mean s_addr field of the structures to get better typed pointers
2012-01-02lib: address type-punned pointers in prefix_same()Denis Ovsienko
IPV4_ADDR_SAME() wasn't passed the right union member, this could cause a bug due to strict-aliasing. IPV6_ADDR_SAME() case got its fix before the error could be created by macro upgrade.

2012-01-02ospfd: fix packet reception for FreeBSD 10.Dmitrij Tejblum
* ospf_packet.c (ospf_recv_packet): FreeBSD, starting from version 10, will not subtract the IP header size from ip_len. This is the patch from FreeBSD's ports/net/quagga/files/patch-ospfd__ospf_packet.c, by Boris Kovalenko.
2012-01-02zebra: ZEBRA_HELLO and mopping up routes (BZ#448)Vyacheslav Trushkin
ZEBRA_HELLO message is used by routing daemons to inform zebra what type of routes daemon will be announcing to zebra. Also zebra uses route_type_oaths array to track which daemon announces which protocol. Zebra mops up routes if daemon didn't for some reason.
2012-01-02lib: fix type-punning in ip_masklen()Denis Ovsienko
ip_masklen() was likely to return incorrect results after being compiled with -fstrict-aliasing (-O2, -O3, -Os)
2012-01-02lib: optimize ip_masklen()Denis Ovsienko
The new implementation makes use of a 64KB mapping table, which makes it possible to compute masklen faster and with constant execution time. The map also allows for additional version of the function, which can detect errors in input argument. The previous implementation had a variable cost of execution, which depended on masklen in a non-linear manner, and at its worst (/31) was 4 times slower, than the new implementation. The only case of old function just slightly outperforming the new one is /0, which is of little practical interest.
