2011-12-07ospfd: remove unused codeStephen Hemminger
The code for nssa_range and other bits that were written but never used.
2011-12-06bgpd: store nexthop info for redistributed IPV6 routesStephen Hemminger
BGP was ignoring nexthop info for static and other redistributed routes for IPv6. Build extra attribute info to store the nexthop. See also: https://bugzilla.vyatta.com/show_bug.cgi?id=6073
2011-12-06ospfd: avoid redundant lookup in ospf_redistribute_withdrawStephen Hemminger
The old algorithim looked up every node twice as it withdrew the entry. It looks up entry once in redistribute_withdraw, then looks it up again info_delete. Use result of first lookup to do the free directly. This may explain the slow performance observed in https://bugzilla.vyatta.com/show_bug.cgi?id=4421
2011-12-06lib: fix memory leak on connect() failureStephen Hemminger
Change sockunion_log() to not use strdup(). This fixes a small memory leak that occurs on every failed connect(), and is simpler/cleaner.
2011-12-06lib: call filter delete hook before freeing access listStephen Hemminger
The delete_hook was being run after calling access list delete function. This would cause ospf to dereference a NULL, in ospf_filter_update because 'access->name' was already freed. See also: https://bugzilla.vyatta.com/show_bug.cgi?id=7654
2011-12-03bgpd: fix memory leak for extra attributesOleg A. Arkhangelsky
this fixes commit b881c7074bb698aeb1b099175b325734fc6e44d2
2011-11-22doc: rectify "match ip next-hop" in ripd (BZ#537)Roderick Schertler
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.

2011-11-21bgpd: fix AS4_PATH attr flag check (BZ#676)Denis Ovsienko
AS_PATH is a well-known, transitive path attribute and cannot be flagged as "Partial". This is what commit 77a20b8af32c926176f8492a086d9e4ec670496b implemented, but it did not account, that bgp_attr_aspath() is also used to process AS4_PATH, which is an optional, transitive path attribute and as such may be flagged as "Partial". This change justfies the test condition.
2011-11-21bgpd: fix 2 more cases of length error reportingDenis Ovsienko
* bgp_attr.c (bgp_attr_originator_id, bgp_attr_cluster_list): use bgp_notify_send_with_data()
2011-11-21lib: use prefix bit length macrosDenis Ovsienko
2011-11-21ospfd: use IS_LSA_SELF() where appropriateDenis Ovsienko
2011-11-21bgpd: 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

2011-11-21bgpd: check AGGREGATOR attr flags (BZ#678)Denis Ovsienko

2011-11-21lib: optimize apply_mask_ipv4()Denis Ovsienko
2011-11-21bgpd: fix error message in bgp_attr_aspath()Denis Ovsienko
2011-11-21lib: make masklen2ip6() safer and fasterDenis Ovsienko
2011-11-21vty_serv_sock_family unusedStephen Hemminger
If the vty_serv_sock_addrinfo is being used, then vty_serv_sock_family is unsed. Fix by adjusting ifdef/else/endif
2011-11-21ospf6d: decode message type with LOOKUP()Denis Ovsienko
* ospf6_message.h * OSPF6_MESSAGE_TYPE_CANONICAL(): dismiss * OSPF6_MESSAGE_TYPE_NAME(): dismiss * ospf6_message.c * ospf6_message_type_str: rewrite as a message list, add max value * ospf6_packet_examin(): update to use LOOKUP() * ospf6_receive(): idem * ospf6_send(): idem
2011-11-21lib: address -Wunused-but-set-variableDenis Ovsienko
* if.c * if_dump(): 'node', 'c' * distribute.c * distribute_list_all(): 'dist' * distribute_list(): 'dist' * districute_list_prefix_all(): 'dist' * if_rmap.c * if_rmap(): 'if_rmap' * vty.c * vty_accept(): 'vty'
2011-11-21lib: spellingDenis Ovsienko
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.

2011-11-17ospf6d: 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.

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()
