2011-10-17bgpd: check ORIGINATOR_ID attribute flagsDenis Ovsienko
* bgp_attr.c * bgp_attr_originator_id(): accept extra argument, add checks for "optional", "transitive" and "partial" bits, log each error condition independently * bgp_attr_parse(): provide extra arguments
2011-10-17bgpd: fix regression in improved attr flag checksDenis Ovsienko
Commit 2febf323411c1aed9d7694898f852ce2ef36a7e5 assumed every flag bit except optional/transitive/partial unset, which at times could not be true for "extended length" bit. * bgp_attr.c * bgp_attr_origin(): exclude BGP_ATTR_FLAG_EXTLEN from comparison * bgp_attr_nexthop(): idem * bgp_attr_med(): idem * bgp_attr_local_pref(): idem * bgp_attr_atomic(): idem
2011-10-17bgpd: improve attr flags checksDenis Ovsienko
Do not check each of the Optional/Transitive/Partial attribute flag bits, when their only valid combination is known in advance, but still perform bit-deep error message logging. This change assumes unused (low-order) 4 bits of the flag octet cleared. * bgp_attr.c * bgp_attr_origin(): rewrite check * bgp_attr_nexthop(): idem * bgp_attr_med(): idem * bgp_attr_local_pref(): idem * bgp_attr_atomic(): idem
2011-10-17bgpd: add missing "partial" flag checks (BZ#676)Denis Ovsienko
ORIGIN handling function used to have "partial" bit check and recent commits added it for NEXT_HOP, MULTI_EXIT_DISC and ATOMIC_AGGREGATE cases. This commit adds "partial" check for AS_PATH and LOCAL_PREF cases, which should leave attributes 1 through 6 inclusive completely covered with attribute flags checks. * bgp_attr.c * bgp_attr_origin(): use bit-by-bit checks for better diagnostics * bgp_attr_aspath(): add flag check * bgp_attr_local_pref(): idem

2011-10-17lib: compile even without IPV6_TCLASSDenis Ovsienko
2011-10-17IPv6 transport class suppportStephen Hemminger
IPv6 supports the same concept of differentiated service for routing protocols as IPv4, but like too many things, the standards committee decided that having two names for the same thing wasn't good enough and introduced a third more generic term transport class. The socket option to set transport class works the same as IPv4, but the arguments are different. * lib/sockopt.[ch] * setsockopt_ipv6_tclass(): new function * bgpd/bgp_network.c * bgp_connect(): set socket option * bgp_listener(): set socket option * ospf6d/ospf6_network.c * ospf6_set_transport_class(): new function * ospf6_serv_sock(): set socket option * ripngd/ripngd.c * ripng_make_socket(): set socket option

2011-10-08bgpd: fix parsing of graceful restart cap. (#663)Peter Pentchev
"While setting up a testbed, I ran across a little problem in the parsing of the "graceful restart" BGP capability that resulted in Quagga not actually activating it for the peer in question - when the peer sent a single AFI/SAFI block." * bgp_open.c * bgp_capability_restart(): actually process the last AFI/SAFI block

* lib/prefix.h * IPV4_CLASS_DE(): new helper macro * bgp_attr.c * bgp_attr_nexthop(): add check for "partial" bit, refresh flag error reporting, explain meaning of RFC4271 section 6.3 and implement it Conflicts: bgpd/bgp_attr.c
2011-09-29bgpd: rename SAFI 3 according to RFC4760Denis Ovsienko
- SAFI value 3 is reserved. It was assigned by RFC 2858 for a use that was never fully implemented, so it is deprecated by this document. * zebra.h: rename macro * bgp_fsm.c: (bgp_graceful_restart_timer_expire, bgp_graceful_stale_timer_expire, bgp_stop, bgp_establish): update * bgpd.c: (peer_nsf_stop): update * bgp_open.c: (bgp_capability_vty_out): SAFI 3 isn't a recognized case any more
2011-09-29bgpd: more SAFI fixesDenis Ovsienko
(with resolved conflict in bgpd/bgp_packet.c) Two macros resolving to the same integer constant broke a case block and a more thorough merge of BGP_SAFI_VPNV4 and BGP_SAFI_VPNV6 was performed. * bgpd.h: MPLS-labeled VPN SAFI is AFI-independent, switch to single * macro * bgp_capability_test.c: update test data * bgp_mp_attr_test.c: idem * bgp_route.c: (bgp_maximum_prefix_overflow, bgp_table_stats_vty) update macro and check conditions (where appropriate) * bgp_packet.c: (bgp_route_refresh_send, bgp_capability_send, bgp_update_receive, bgp_route_refresh_receive): idem * bgp_open.c: (bgp_capability_vty_out, bgp_afi_safi_valid_indices, bgp_open_capability_orf, bgp_open_capability): idem * bgp_attr.c: (bgp_mp_reach_parse, bgp_packet_attribute, bgp_packet_withdraw): idem
2011-09-29bgpd: fix SAFI for for MPLS labeled VPN-IPv6Denis Ovsienko
* bgpd.h: change value of BGP_SAFI_VPNV6 to 128 (RFC4659, BZ#659) * bgp_route.c: (bgp_table_stats_vty) fix length argument to strncmp()
