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.
2011-11-17ospf6d: check MTU with message header size in mindDmitrij Tejblum
* ospf6_message.c: (ospf6_packet_max): new function, return maximum IPv6 payload on an interface; (ospf6_hello_send, ospf6_dbdesc_send, ospf6_dbdesc_send_newone, ospf6_lsreq_send, ospf6_lsupdate_send_neighbor, ospf6_lsupdate_send_interface, ospf6_lsack_send_neighbor, ospf6_lsack_send_interface): compare message size with the maximum payload instead of the MTU.

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.

2011-10-26bgpd: fix 2 more cases of length error reportingDenis Ovsienko
* bgp_attr.c (bgp_attr_originator_id, bgp_attr_cluster_list): provide required arguments to bgp_attr_malformed()

* bgp_attr.c * bgp_attr_aggregator(): check Optional/Transitive flag bits

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()

2011-10-18bgpd: use bgp_attr_malformed()Denis Ovsienko
Some of the recent attribute flags/length checks copied from QRE use bgp_notify_send_with_data() directly, but master branch assumes using bgp_attr_malformed(). * bgp_attr.c * bgp_attr_med() * bgp_attr_local_pref() * bgp_attr_atomic() * bgp_attr_originator_id() * bgp_attr_cluster_list() * bgp_mp_reach_parse() * bgp_mp_unreach_parse()
2011-10-17bgpd: add flag checks for MP_(UN)REACH_NLRIDenis Ovsienko
* bgp_attr.[ch] * bgp_mp_reach_parse(): add extra arguments and a uniform flag check block * bgp_mp_unreach_parse(): idem * bgp_attr_parse(): provide extra arguments * bgp_mp_attr_test.c * parse_test(): justify respective calls
2011-10-17bgpd: fix spelling of CLUSTER_LISTDenis Ovsienko
2011-10-17bgpd: check CLUSTER_LIST attribute flagsDenis 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

2011-10-17ospf6d: 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.

2011-10-17ospfd: 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

"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
