2012-01-02zebra: ZEBRA_HELLO and mopping up routes (BZ#448)Vyacheslav Trushkin
ZEBRA_HELLO message is used by routing daemons to inform zebra what type of routes daemon will be announcing to zebra. Also zebra uses route_type_oaths array to track which daemon announces which protocol. Zebra mops up routes if daemon didn't for some reason.
2012-01-02lib: fix type-punning in ip_masklen()Denis Ovsienko
ip_masklen() was likely to return incorrect results after being compiled with -fstrict-aliasing (-O2, -O3, -Os)
2012-01-02lib: optimize ip_masklen()Denis Ovsienko
The new implementation makes use of a 64KB mapping table, which makes it possible to compute masklen faster and with constant execution time. The map also allows for additional version of the function, which can detect errors in input argument. The previous implementation had a variable cost of execution, which depended on masklen in a non-linear manner, and at its worst (/31) was 4 times slower, than the new implementation. The only case of old function just slightly outperforming the new one is /0, which is of little practical interest.
2012-01-01Revert "lib: optimize apply_mask_ipv6()"Denis Ovsienko
Experience with IPv4 counterpart of this function suggests, that this way of type-punning is likely to cause errors.

2011-12-14ospf6d: always remove the result of a previous SPF calculationTom Goff
This is needed to avoid stale routes in some cases; the regression was introduced by commit 1d19234e79c77a7d55194b513f2a77c6a691bc2c. * ospf6_spf.c: (ospf6_spf_calculation) Call ospf6_spf_table_finish() before possibly returning if no router-LSA is found for the root of the SPF tree.

2011-12-13ospf6d: 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()

2011-12-13lib: 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. Conflicts: lib/sockunion.c
2011-12-13lib: 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
2011-12-13zebra: fix redistribution of new protocolsDavid Lamparter
redistribute is currently limited to "known" protocols. there is no reason for this limitation, so, remove it.
2011-12-13rib: 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)
2011-12-13build: 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")
2011-12-13zebra: 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().

2011-12-13lib: clearing zclient.c for some cases of buildingVyacheslav Trushkin
lib/zclient.c: using of HAVE_TCP_ZEBRA in zclient_socket_* definitions extended by else clause.
2011-12-13quagga: option "-z" ("--socket <path>") addedVyacheslav Trushkin
All daemons modified to support custom path to zserv socket. lib: generalize a zclient connection zclient_socket_connect added. zclient_socket and zclient_socket_un were hidden under static expression. "zclient_serv_path_set" modified.

2011-12-13ripngd: limit max of "timers basic" to 65535 as documentedUlrich Weber
and use VTY_GET_INTEGER_RANGE instead of calling strtoul
2011-12-13bgp: use VTY_GET_INTEGER_RANGE() in bgp_clear()Ulrich Weber
Second patch replaces "VTY_GET_LONG ("AS", as_ul, arg);" by "VTY_GET_INTEGER_RANGE ("AS", as, arg, 1, BGP_AS4_MAX);" as done in all other code, which parses AS numbers.
2011-12-13ospf6d: implement 'match interface' for route-mapsVyacheslav Trushkin
ospf6_routemap_rule_match_interface* was imported from ospfd daemon with minor changes. new CLI options defined. `ospf6_routemap_rule_match_interface' was changed to support IPv6 (ospfv3) route's external information.
2011-12-07lib: fix SMUX compiler warningsStephen Hemminger
Make progname a string, and cast when calling asn1. Remove variable set but never used.
2011-12-07lib: fix compile warnings from set-never-usedStephen Hemminger
The if_dump code had empty loop, that caused set-never-used warning.
2011-12-07ospf6d: fix compile warning from falling off end of mainStephen Hemminger
ospf6 main always calls ospf6_exit() which always calls exit. Use attributes to tell GCC that this is ok.
2011-12-07zebra: fix warnings in forward procStephen Hemminger
Check result of fgets(), and don't set variable that is never used.
2011-12-07bgpd: cleanup privs on terminationStephen Hemminger
When doing valgrind testing, the privledges from zprivs_init() need to be cleaned up on exit.
2011-12-07vty_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

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

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.
