2011-12-13build: delete .cvsignore filesDenis Ovsienko
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
2011-09-30bgpd: improve NEXT_HOP attribute checks (BZ#680)Denis Ovsienko
* 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
2011-09-27lib: remove unused variableDenis Ovsienko
* sockopt.c (getsockopt_ifindex): "ifindex" was never used

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.
2011-03-21lib: Fix accounting of memoryChris Hall
* lib/memory.c: (zrealloc) If is called with NULL pointer then it should increment allocations because it behaves the same as zmalloc. (zfree) is called with NULL pointer, it does nothing therefore allocation count should not change.
2010-12-08lib: Fix bug in prefix trie lookupPaul Jakma
* lib/table.c: (route_node_match) fix overshoot that was causing this function to go 1 bit too far and thus reading past end of prefix. (route_node_lookup) be defensive - don't assume others will clean up leaves when removing info.
2010-12-08lib: prefix.c nano-optimisationPaul Jakma
* lib/prefix.c: (prefix_match) nano-optimisation, let it return early without copying pointers.
2010-12-08lib: Make workqueue more conservative about ramping upPaul Jakma
* workqueue.c: (work_queue_run) Err more on the side of keeping granularity down, by being more conservative about increasing it. Also, fix mispelling.
2010-12-08lib: Add a command to clear the thread CPU history dataPaul Jakma
* (general) this can be useful when investigating thread latency problems, when you don't want to have to restart a daemon between tests. * thread.c: (cpu_record_(hash_)clear) wipe the stored thread cpu history data, according to the filter, similar to the vty print code. (clear_thread_cpu_cmd) new command to clear data. * thread.h: export new command * command.c: install it
2010-12-08lib: Thread scheduler should be fair and not let events starve I/O and timersPaul Jakma
* thread.c: (thread_fetch) the current scheduler will service events indefinitely, ignoring I/O and timers, so long as there are events. In other words, events can crowd out I/O and timers. In theory this shouldn't be a huge problem as events are generated only by timers and I/O, however in practice it means normal-load behaviour is not as useful a predictor of high-load behaviour as it should be. Fix this by considering all the kinds of threads, in every run of the scheduler. For any given run, we prioritise events, however across runs the scheduler should be fair. This has been observed to give more stable inter-packet times in testing of ospfd (i.e. lower std-dev). (thread_process) new heler to queue all the given threads onto the ready list
2010-12-08lib: thread history funcname shouldn't be constant, it's freedPaul Jakma
* thread.h: (struct cpu_thread_history.funcname) malloc gets called on this so it should not be const * thread.c: (cpu_record_print) cast the (const char *) to (char *), this function knows what it's doing (free wont be called on it).
2010-10-18zclient: fix router-id calculation for IPv6 (#595)Dmitry Tejblum
If router-id is not specified in ospf6d.conf, ospf6d will get it from the zebra daemon. But ospf6d originates Link LSAs before the router-id is returned by zebra, thus this router's Link LSAs will be flooded with AdvRouter set to 0. * zclient.c: zclient_start(): send ZEBRA_INTERFACE_ADD message after ZEBRA_ROUTER_ID_ADD, not before
2010-10-06bgpd, lib: adopt afi_t and safi_t in several placesMichael Lambert
* bgpd/bgp_attr.c, bgpd/bgp_open.h, bgpd/bgp_route.c, lib/prefix.c, lib/prefix.h: Various integer types were being used where, if we had strict type checking, afi_t and safi_t would be required.

2010-01-27lib: undo the last PIE commitStephen Hemminger
Stephen: A recent change breaks build Quagga on Debian Lenny with amd64 (but not i386). Not sure whether this is cause by ld, gcc, or libtool; but whatever it just won't work for a large number of users. Mathias: I would guess it's a problem of libtool because it adds "-fPIC -DPIC" to the compiler flags but doesn't remove -fPIE. That wouldn't be a problem if the compiler would ignore the -fPIE in favor to the latter -fPIC, but obviously it does not. [...] Those objects were actually compiled with -fPIC but also -fPIE which seems to confuse gcc.
2010-01-20lib: fix PIE build flagsMathias Krause
Because the final executables are built as position independent executables (PIE) -- when configure has detected compiler supported for PIE -- the objects in the library archive must be built in that way, too. Otherwise the runtime linker has to do unneccesary relocation for each start of the program. Even worse, the programs won't even be able to start on a (hardened) kernel that doesn't allow those relocations to happen by preventing making the .text segment writable (PaX's MPROTECT feature comes to mind). The attached patch fixes this issue by adding the appropriate flags to the Makefile.am.
2010-01-13lib: fix memory loggingDavid Ward
* lib/memory.h * mtype_zcalloc(): correct function prototype * XFREE(): make both definitions consistent in setting the pointer to NULL after freeing the memory These changes will only have an effect if MEMORY_LOG is defined (it is not by default).
2009-12-21lib: make some structures constantStephen Hemminger
* isisd/isis_pdu.c * maskbit: this pre-initialized array is not modified * lib/prefix.c * maskbit: idem * lib/command.c * facility_map: idem * itoa64: idem * default_motd: make local var static * facility_name(): update local var accordingly * facility_match(): idem
2009-12-10ospf6d: fix warnings from recent prefix bit commitStephen Hemminger
* lib/prefix.h * prefix6_bit(): add IPv6 wrapper for prefix_bit() * ospf6d/ospf6_lsdb.c * ospf6_lsdb_type_router_head(): employ prefix6_bit() * ospf6_lsdb_type_head(): idem
2009-12-09lib: move check_bit into prefix common codeStephen Hemminger
Make one version of check prefix bit, and put it inline with proper prototype. This gets rid of some macro's and also some assert() that can never happen on a non-broken compiler. * bgpd/bgp_table.c * CHECK_BIT(): sayonara * check_bit(): sayonara * SET_LINK(): sayonara * set_link(): make use of prefix_bit() instead of check_bit() * bgp_node_match(): idem * bgp_node_lookup(): idem * bgp_node_get(): idem * lib/prefix.h * prefix_bit(): new inline version of check_bit() * lib/table.c * CHECK_BIT(): sayonara * check_bit(): sayonara * SET_LINK(): sayonara * set_link(): make use of prefix_bit() instead of check_bit() * route_node_match(): idem * route_node_lookup(): idem * route_node_get(): idem * ospf6d/ospf6_lsdb.c * CHECK_BIT(): sayonara * ospf6_lsdb_lookup_next(): make use of prefix_bit() instead of CHECK_BIT() * ospf6_lsdb_type_router_head(): idem * ospf6_lsdb_type_head(): idem * ospf6d/ospf6_route.c * CHECK_BIT(): sayonara * ospf6_route_match_head() make use of prefix_bit() instead of * CHECK_BIT()
2009-12-09lib: fix warning on little endianStephen Hemminger
* md5.c * md5_calc(): If building on little endian then X will be 'const uint32_t' which causes compiler warning in code that never gets used. Just move the endif to make sure code is not checked.
2009-12-08lib: make match functions take const argsStephen Hemminger
