2012-01-08lib: use prefix bit length macrosDenis Ovsienko
2012-01-06lib/if: trivial, fix rarely used if debug function to print everythingPaul Jakma
* if.c: (if_dump) loop that doesn't do anything, wants to be before the zlog of what it's meant to print out so all the connected addresses get printed out. Trival: just a debug function
2012-01-06general: remove inline qualifiers and move in-header functions to objectsPaul Jakma
* (general) Move functions in headers into files, to be compiled into shared object files. Remove inline qualifier from functions. Let the compiler do the work.

...otherwise 4294967295 is not a valid value on 32bit systems
2012-01-02lib: address type-punned pointers in prefix_same()Denis Ovsienko
IPV4_ADDR_SAME() wasn't passed the right union member, this could cause a bug due to strict-aliasing. IPV6_ADDR_SAME() case got its fix before the error could be created by macro upgrade.
2012-01-02bgpd: justify checks for IPv4 class D/EDenis Ovsienko
* lib/prefix.h * IPV4_CLASS_DE(): make consistent with counterpart macros * bgp_packet.c * bgp_open_receive(): test using macro instead of ">=" * bgp_route.c * bgp_update_rsclient(): idem * bgp_update_main(): idem
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.

2011-12-13lib: 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

2011-12-13lib: 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.
2011-12-07lib: 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.
2011-12-07vty_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
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
2011-11-21lib: 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.
2011-10-17lib: 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

* lib/prefix.h * IPV4_CLASS_DE(): new helper macro * bgp_attr.c * bgp_attr_nexthop(): add check for "partial" bit, refresh flag error reporting, explain meaning of RFC4271 section 6.3 and implement it Conflicts: bgpd/bgp_attr.c
2011-09-29bgpd: rename SAFI 3 according to RFC4760Denis Ovsienko
- SAFI value 3 is reserved. It was assigned by RFC 2858 for a use that was never fully implemented, so it is deprecated by this document. * zebra.h: rename macro * bgp_fsm.c: (bgp_graceful_restart_timer_expire, bgp_graceful_stale_timer_expire, bgp_stop, bgp_establish): update * bgpd.c: (peer_nsf_stop): update * bgp_open.c: (bgp_capability_vty_out): SAFI 3 isn't a recognized case any more
2011-09-27lib: provide more information in case of failed LOOKUP.Dmitrij Tejblum
* log.[ch] * mes_lookup: add a parameter with the name of the message list, print the name in case of failure. * LOOKUP macro: pass the name of the message list.
2011-09-27lib: use "protocol-independed API" from RFC3678, if that is availableDmitrij Tejblum
(This commit is based on the patch from BZ#420, and should fix that bug.) * configure.ac: detect availability of that API * sockopt.c (setsockopt_ipv4_multicast): use it for join/leave IPv4 multicast groups
2011-09-27lib: futher simplification of setsockopt_ipv4_multicast()Dmitrij Tejblum
* sockopt.c (setsockopt_ipv4_multicast): check for wrong optname with assert(), rather than return an error.
2011-09-27lib: fix omission in the previous commit to lib/sockopt.cDmitrij Tejblum
* sockopt.c (setsockopt_ipv4_multicast_if): fix missed line in the previous commit.
2011-09-27lib: simplify interface of setsockopt_multicast_ipv4().Dmitrij Tejblum
* sockopt.[ch] (setsockopt_ipv4_multicast): ifindex is now mandatory (all non-ancient OSes can use it anyway), and if_addr parameter (the address of the interface) is now gone. (setsockopt_ipv4_multicast_if): IP_MULTICAST_IF processing moved to this new function * ospf_network.c (ospf_if_add_allspfrouters, ospf_if_drop_allspfrouters, ospf_if_add_alldrouters, ospf_if_drop_alldrouters, ospf_if_ipmulticast), rip_interface.c (ipv4_multicast_join, ipv4_multicast_leave, rip_interface_new): adapt to the new interface

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
2011-03-24lib: 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.
2011-03-23lib: 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
2011-03-21lib: add TCP_CORK wrapperStephen Hemminger
* sockunion.{c,h}: (sockopt_cork) wrapper for TCP_CORK socket option for those platforms that provide it. For other platforms, it is just a nop.
2011-03-21lib: zlog should clean up its memoryTom Goff
* log.c: (closezlog) Also free the dynamically allocated filename when a log is closed.
2011-03-21lib: Add a function to delete all interfacesTom Goff
if.c: (if_terminate) This adds a cleanup function that can be called when a daemon exits, similar to vty_terminate().
2011-03-21lib: Better hashing of string values using Bernstein hashStephen Hemminger
* hash.{h,c}: (string_hash_make) Hash optimised for strings, current implementation using Bernstein hash, which offers a good compromise between distribution and performance. * distribute.c: (distribute_hash_make) use previous instead of additive string hash. * if_rmap.c: (if_rmap_hash_make) ditto
2011-03-21bgpd: fix bgp_node locking issuesChris Caputo
* bgpd: Connected table locks were being locked but not unlocked, such that eventually a lock would exceed 2^31 and become negative, thus triggering an assert later on. * bgp_main.c: (bgp_exit) delete connected elements along with ifp's. * bgp_nexthop.c: (bgp_nexthop_lookup{,_ipv6}) add missing unlocks (bgp_multiaccess_check_v4) ditto (bgp_connected_{add,delete}) Use a distinct memtype for bgp_connected_ref. (bgp_scan_finish) reset the nexthop cache to clean it up when bgpd exits * bgp_route.c: fix missing bgp_node unlocks * lib/memtype.c: (memory_list_bgp) add MTYPE_BGP_CONN * testing: has been tested for almost 2 months now.
