2011-09-27ospf6d: fix crash on filter-list handling (BZ#530)Christian Hammers
This essentially merges the fix available from Debian build of Quagga. * ospf6_area.c * area_filter_list(): use correct argv indices * no_area_filter_list(): idem
2011-09-27configure: fix FreeBSD header detection (BZ#408)Denis Ovsienko
This change is based on Xavier Beaudouin's patch (which fixes detection of 3 config.h macros on FreeBSD without any impact to Linux build of Quagga) and FreeBSD port patch (which fixes 5 config.h macros, but breaks the Linux build), it fixes 5 macros and works for both FreeBSD 8 and Linux.

2011-09-27isisd: raise hello rate for DIS (BZ#539)Fritz Reichmann
* isis_pdu.c: Divide hello interval by three, depending if we are DIS or not.
2011-09-27isisd: fix crash on "no router isis" (BZ#536)Fritz Reichmann
The crash is due to threads accessing data that gets destroyed during the removal of the configuration. * isis_circuit.c: Destroy adjacencies to stop adjacency expiry thread. Stop PSNP threads. * isisd.c: Change state of circuit back to INIT and reassign the circuit structure to isis->init_circ_list rather than destroying the circuit data structure. Stop SPF threads. Stop LSP generation threads. * isisd.h: Add pointers to LSP threads into area structure in order to stop them in isisd.c * isis_lsp.c: Store pointer to LSP thread in area structure. * isis_pdu.c: Stop PDU generation for a circuit with a removed area. * isis_pfpacket.c: Stop processing received PDUs for a circuit with a removed area.
2011-09-27configure: dismiss libutil.hStephen Hemminger
Recent versions of libc on Linux (Debian Testing) create lots of compile warnings about direct usage of libutil.h
2011-09-27zebra: fix loss of metric for Linux routesDmitry Popov
* rt_netlink.c * netlink_route_change(): fetch metric information like netlink_routing_table() does and pass it further
2011-09-27ospfd: remove useless RFC1583 checkAlexandre Chappuis
* 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.

2011-09-27doc: BGP route-flap dampeningAlexandre Chappuis
2011-09-27doc: add missing wordAlexandre Chappuis
* ospfd.texi: Adjust meaning of the rfc1583compatibility option in order to match the RFC specification and the actual source code.

2011-09-26ospf6d: CVE-2011-3323 (fortify packet reception)Denis Ovsienko
This vulnerability (CERT-FI #514840) was reported by CROSS project. ospf6d processes IPv6 prefix structures in incoming packets without verifying that the declared prefix length is valid. This leads to a crash caused by out of bounds memory access. * ospf6_abr.h: new macros for size/alignment validation * ospf6_asbr.h: idem * ospf6_intra.h: idem * ospf6_lsa.h: idem * ospf6_message.h: idem * ospf6_proto.h: idem * ospf6_message.c * ospf6_packet_minlen: helper array for ospf6_packet_examin() * ospf6_lsa_minlen: helper array for ospf6_lsa_examin() * ospf6_hello_recv(): do not call ospf6_header_examin(), let upper layer verify the input data * ospf6_dbdesc_recv(): idem * ospf6_lsreq_recv(): idem * ospf6_lsupdate_recv(): idem * ospf6_lsack_recv(): idem * ospf6_prefixes_examin(): new function, implements A.4.1 * ospf6_lsa_examin(): new function, implements A.4 * ospf6_lsaseq_examin(): new function, an interface to above * ospf6_packet_examin(): new function, implements A.3 * ospf6_rxpacket_examin(): new function, replaces ospf6_header_examin() * ospf6_header_examin(): sayonara * ospf6_receive(): perform passive interface check earliest possible, employ ospf6_rxpacket_examin()
2011-09-26ospf6d: CVE-2011-3324 (DD LSA assertion)Denis Ovsienko
This vulnerability (CERT-FI #514839) was reported by CROSS project. When Database Description LSA header list contains trailing zero octets, ospf6d tries to process this data as an LSA header. This triggers an assertion in the code and ospf6d shuts down. * ospf6_lsa.c * ospf6_lsa_is_changed(): handle header-only argument(s) appropriately, do not treat LSA length underrun as a fatal error.
2011-09-26ospfd: CVE-2011-3325 part 2 (OSPF pkt type segv)Denis Ovsienko
This vulnerability (CERT-FI #514838) was reported by CROSS project. The error is reproducible only when ospfd debugging is enabled: * debug ospf packet all * debug ospf zebra When incoming packet header type field is set to 0x0a, ospfd will crash. * ospf_packet.c * ospf_verify_header(): add type field check * ospf_read(): perform input checks early
2011-09-26ospfd: CVE-2011-3325 part 1 (OSPF header underrun)Denis Ovsienko
This vulnerability (CERT-FI #514838) was reported by CROSS project. When only 14 first bytes of a Hello packet is delivered, ospfd crashes. * ospf_packet.c * ospf_read(): add size check
2011-09-26ospfd: CVE-2011-3326 (uknown LSA type segfault)CROSS
This vulnerability (CERT-FI #514837) was reported by CROSS project. They have also suggested a fix to the problem, which was found acceptable. Quagga ospfd does not seem to handle unknown LSA types in a Link State Update message correctly. If LSA type is something else than one supported by Quagga, the default handling of unknown types leads to an error. * ospf_flood.c * ospf_flood(): check return value of ospf_lsa_install()
2011-09-26bgpd: CVE-2011-3327 (ext. comm. buffer overflow)CROSS
This vulnerability (CERT-FI #513254) was reported by CROSS project. They have also suggested a fix to the problem, which was found acceptable. The problem occurs when bgpd receives an UPDATE message containing 255 unknown AS_PATH attributes in Path Attribute Extended Communities. This causes a buffer overlow in bgpd. * bgp_ecommunity.c * ecommunity_ecom2str(): perform size check earlier
2011-08-27ospf6d: add missing includeDenis Ovsienko
Two extern declarations in ospf6_abr.h are based on struct ospf6_route, which may not be available at the time ospf6_abr.h is included. This may lead to warnings after including ospf6_abr.h just for the structures defined in it.
2011-08-27ospf6d: move named constants to ospf6d.hDenis Ovsienko
2011-08-27ospf6d: justify some ABR debug codeDenis Ovsienko
* ospf6_abr.c * ospf6_abr_examin_summary(): only fill "buf" when it is used

2011-04-22ospf6d: copy "mtu-ignore" option from ospfdDmitrij Tejblum
"mtu-ignore" is an option ospfd used to mimic from the vendor's implementation, now ospf6d will also implement it. * ospf6_interface.h: extend ospf6_interface structure by one flag * ospf6_interface.c: (ipv6_ospf6_mtu_ignore, no_ipv6_ospf6_mtu_ignore): new declarations; (ospf6_interface_create): show initial value for consistency; (ospf6_interface_show): print flag status * ospf6_message.c: (ospf6_dbdesc_recv): consider interface-specific flag when checking MTU

2011-04-01bgpd: fix memory leak when deleting a communityMichael Lambert
* bgp_routemap.c: (route_set_community_delete) When deleting a community in a route-map the old community was being orphaned. Like the description of the same code in route_set_community, this is a hack, not a true fix.

2011-03-29bgpd: Fix merge error in jhash commitPaul Jakma
* bgp_attr.c: (attrhash_key_make) 98e30f should have changed jhash2 to jhash. These kinds of merge errors would be reduced and life would be easier if people would submit fully-formed fixes that could be chucked directly into git-am.
2011-03-28bgpd: refine the setting up of GTSMStephen Hemminger
* bgpd.h: Add error code for setting GTSM on iBGP * bgpd.c: (peer_ttl_security_hops_set) use previous error code and signal incompatibility of GTSM+iBGP to vty. Consider the session state when setting GTSM, and reset Open/Active peers to let them pick up new TTL from start.
2011-03-24build: treat opaque-lsa default correctly for ospfapiGreg Troxel
In deciding whether to default ospfapi to on or off, use the same rule for opaque-lsa as earlier: != no rather than = yes, so that not having set it implies yes.
2011-03-24lib: Add support for IPv6 ttl securityStephen Hemminger
* sockunion.c: (sockopt_minttl) Add IPv6 support for min hop count. The kernel support is Linux kernel 2.6.35 or later.
2011-03-24bgpd: Cleanups & fixes for minttl / GTSMStephen Hemminger
* bgp_vty.c: (peer_ebgp_multihop_{un,}set_vty) tail-call cleanup. ({no_,}neighbor_ttl_security) ditto. * bgpd.c: (peer_ttl_security_hops_set) Peer group checks and TTL set only need to be done on transition. * sockunion.c: (sockopt_minttl) remove always-on debug and improve readability.
2011-03-23bgpd: RFC 5082 Generalized TTL Security Mechanism supportNick Hilliard
* bgpd: Add support for RFC 5082 GTSM, which allows the TTL field to be used to verify that incoming packets have been sent from neighbours no more than X IP hops away. In other words, this allows packets that were sent from further away (i.e. not by the neighbour with known distance, and so possibly a miscreant) to be filtered out. * lib/sockunion.{c,h}: (sockopt_minttl) new function, to set a minimum TTL using the IP_MINTTL socket opt. * bgpd.h: (BGP_ERR_NO_EBGP_MULTIHOP_WITH_TTLHACK) define for command error for minttl. (struct peer) add a config variable, to store the configured minttl. (peer_ttl_security_hops_{set,unset}) configuration handlers * bgpd.c: (peer_group_get) init gtsm_hops (peer_ebgp_multihop_{un,}set) check for conflicts with GTSM. Multihop and GTSM can't both be active for a peer at the same time. (peer_ttl_security_hops_set) set minttl, taking care to avoid conflicts with ebgp_multihop. (bgp_config_write_peer) write out minttl as "neighbor .. ttl-security hops X". * bgp_vty.c: (bgp_vty_return) message for BGP_ERR_NO_EBGP_MULTIHOP_WITH_TTLHACK (peer_ebgp_multihop_{un,}set_vty) * bgp_network.c: (bgp_accept) set minttl on accepted sockets if appropriate. (bgp_connect) ditto for outbound.

2011-03-23bgpd: Fix compile failure if IPv6 build was disabled.Paul Jakma
* bgp_route.c: ({no_,}ipv6_bgp_network_ttl_cmd) depends on ipv6_bgp_network which is HAVE_IPV6, so these should be too. (bgp_route_init) and the installs should be similarly ifdefed
2011-03-23lib: fix more format warnings (#637)Christian Hammers
The following patch was also neccessary to compile. * command.c: (config_logmsg_cmd) use "%s" format spec * if.c: (connected_log) ditto
2011-03-22bgpd: attribute jhash call should use a standard interface to in6_addr dataStephen Hemminger
* bgp_attr.c; (attrhash_key_make) s6_addr is only member of in6_addr guaranteed to be available - s6_addr32 isn't. Fix to be more portable, and thus allow compilation on BSD again.
2011-03-22ospfd: Compile fix for opaque supportPaul Jakma
* ospfd: Refresher logic cleanup broke OSPF opaque, which does its own thing with regard to refresher logic and which also, in the protocol, requires implementations to keep state of which OI an LSA is received on (rather than providing information in the LSA to allow it to be looked up - as other LSAs requiring such assocation were careful to do). * ospf_lsa.h: (struct ospf_interface) Add back the pointer to oi, but only for type-9 now. * ospf_nsm.c: (ospf_db_summary_add) check the oi actually exists first - doesn't obviate the need for opaque to ensure oi pointers get cleaned up when ospf_interfaces disappear. * ospf_opaque.{c,h}: (ospf_opaque_functab,ospf_opaque_lsa_refresh) Refresher LSA functions now need to return the LSA to the general refresh logic, to indicate whether the LSA was refreshed.
