2011-11-21lib: add sockopt helper for setting IPV6_V6ONLY and use itDavid Lamparter
getaddrinfo returns a list of socket parameters for listening. it will contain both IPv4 and IPv6 listening sockets. unless we use IPV6_V6ONLY on the IPv6 ones, only the socket listed first will work. if the IPv4 one came first, the IPv6 one would get an "Address in use" error. this functionality was already present for bgpd and its listening sockets. as it is needed for vtys as well, make it a common helper.
2011-11-21lib: put route_types.txt to real useDavid Lamparter
this replaces most occurences of routing protocol lists by preprocessor defines from route_types.h. the latter is autogenerated from route_types.txt by a perl script (previously awk). adding a routing protocol now is mostly a matter of changing route_types.txt and log.c. Conflicts: lib/route_types.awk
2011-11-21zebra: fix redistribution of new protocolsDavid Lamparter
redistribute is currently limited to "known" protocols. there is no reason for this limitation, so, remove it.
2011-11-21rib: default distance value for new protocols (v2)David Lamparter
adding protocols and forgetting to update zebra_rib.c currently causes a beyond end of array access for the default distance value. fix by making 150 the default distance for unknown routing protocols. 150 is higher than all other IGPs but lower than iBGP (200)
2011-11-21build: fixup autoconf for cross-compiling (to OpenWRT)David Lamparter
MALLOC/REALLOC aren't used properly (no rpl_malloc), remove them while at it, infer some sane ipforwarding method from the OS value. (v2 on that, "==" is not a proper operator for standard "test")
2011-11-21zebra: set the interface link-layer socket addressTom Goff
* kernel_socket.c: (ifm_read) The reorganization from commit 6fe70d1b35c189cb1e488b2c26551ba7baac6148 removed setting the interface link-layer socket address structure on routing socket platforms. This restores saving the link-layer information because it might be used elsewhere: rtm_write() when no gateway is given, if_dump_vty() and rtadv_send_packet().
2011-11-21bgpd: remove unused function bgp_bind_addressDavid Lamparter
bgp_bind_address is replaced with sockunion_bind.
2011-11-21bgpd: fix update-source for IPv6 (BZ#548)David Lamparter
if update-source was given as interface name, bgpd was unconditionally trying to bind to an IPv4 address from that interface. change function to find the best-matching (number of address bits) same-family address on the interface.
2011-11-21lib: prefix2sockunion, prefix_common_bits helper functionsDavid Lamparter
prefix2sockunion converts a struct prefix* to a union sockunion *; prefix_common_bits counts the number of common bits in the prefix's address part.
2011-11-15bgpd: fix "nexthop-local unchanged" (BZ#350)Dylan Hall
2011-11-15bgpd: justify capabilities for TOS settingChris Luke
To set the TOS bits on TCP connections, platforms that restrict capabilities need the priv level to be raised before the sockopt is set, and this requires the ZCAP_NET_ADMIN priv. * bgp_main.c: update _caps_p to include ZCAP_NET_ADMIN * bgp_network.c * bgp_connect(): request ZPRIVS_RAISE/ZPRIVS_LOWER * bgp_listener(): request ZPRIVS_RAISE earlier
2011-11-15ospfd: improve fix to CVE-2011-3326 (BZ#586)Thomas Ries
Make ospf_flood() propagate error returned by ospf_lsa_install() further to properly discard the malformed LSA, not just prevent the immediate crash.
2011-11-15bgpd: revised fix to --dryrun (BZ#622)Sergey Y. Afonin
2011-10-19bgpd: fix more regressions in attr flag checksDenis Ovsienko
Commit 05a4936b713b9882171d0f7fb20b8439df23939e fixed some of the attributes involved, but not all. This commit should do it. * bgp_attr.c * bgp_attr_originator_id() * bgp_attr_cluster_list() * bgp_mp_reach_parse() * bgp_mp_unreach_parse()
2011-10-17lib: fix endianness of masklen2ip()Denis Ovsienko
2011-10-17lib: make masklen2ip() safer and fasterDenis Ovsienko
2011-10-17ospf6d: make some old sizing checks assertionsDenis Ovsienko
As long as ospf6_packet_examin() is now the single checkpoint for received packets, most of the old checks performed elsewhere can be converted into assert() constructs. Malformed input data at respective points can be attributed solely to a programming error, not a malformed packet. * ospf6_message.c * ospf6_hello_print() * ospf6_dbdesc_print() * ospf6_lsreq_print() * ospf6_lsupdate_print() * ospf6_lsack_print() * ospf6_hello_recv() * ospf6_dbdesc_recv_master() * ospf6_dbdesc_recv_slave() * ospf6_lsreq_recv() * ospf6_lsupdate_recv() * ospf6_lsupdate_recv() * ospf6_lsack_recv() * ospf6_receive()
2011-10-17zebra: trivial warning fixPaul Jakma
* zebra_routemap.c: (route_set_src) get rid of the dummy family variable.
2011-10-17doc: Add dependency for quagga.pdf make targetPaul Jakma
* doc/Makefile.am: pdf target needs to depend on all the input files.
2011-10-17bgpd: improve "monotonic" uptime correctionJohn Kemp
Older versions of Quagga/Zebra would output a value in MRT table dump files for "uptime" aka "ORIGINATED" that was a WALL clock value. Given that uptime is now internally a bgp_clock MONOTONIC value, the output in the MRT files is showing up as monotonic. Note: time of MRT dump is still recorded correctly as a time() based value, so we haven't lost that value. Proposal is to correct the uptime output on the vty and in the MRT files to again display something more akin to WALL time. * bgp_dump.c: (bgp_dump_routes_func) add conditional correction * bgp_route.c: (route_vty_out_detail) make correction conditional, move variable declaration to beginning of the function
2011-10-17ripngd: copy debug statements fix from ripdStephen Hemminger
Doesn't ripng needs same fix as ripd.
2011-10-17doc: "[no] router zebra" does not belong to ospfdDenis Ovsienko
2011-10-17ospfd: 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.

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
2011-10-17bgpd: ignore 4 bits of attribute flags byteDenis Ovsienko

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

2011-09-26ospf6d: 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
