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
2011-07-20bgpd: Adds support to mark up the BGP rib table entry with multipathJosh Bailey
information based on the multipath list (mp_list) generated during the best path calculation. Display "multipath" for paths that are multipath and also on bestpath if the route is multipath. Flag a best path with the BGP_INFO_MULTIPATH_CHG if the multipath set has changed since the last update. This can be used to trigger updates to zebra and peers. The multipath markup is a lazily allocated bgp_info_mpath structure that is added to the best path and any multipaths. The mpath structures are linked together with the best path element at the head and the other elements ordered by nexthop and then by peer address. This markup scheme is updated by calling bgp_info_mpath_update() and passing in a new mp_list the the current multipath set. There are additional API's for walking the multipath set, querying the count of multipaths, and for cleaning up the multipath markup information when freeing path information. * bgpd/bgp_mpath.c * bgp_info_mpath_new(): Allocation of new mpath element * bgp_info_mpath_free(): Release memory for mpath element * bgp_info_mpath_get(): Access mpath element of path. Allocate memory on-demand * bgp_info_mpath_enqueue(): Enqueue a path onto the multipath list * bgp_info_mpath_dequeue(): Remove a path from the multipath list * bgp_info_mpath_first(): Return first path on the multipath list * bgp_info_mpath_next(): Return next path on the multipath list * bgp_info_mpath_count(): Return the number of paths on the multipath list * bgp_info_mpath_count_set(): Set the number of paths on the multipath list * bgp_info_mpath_update(): Update multipath markup on bgp route table entry and flag any changes. Emit 'debug bgp event' output on any multipath change. * bgpd/bgp_mpath.h * struct bgp_info_mpath: Information added to a bgp_info path to record multipath information * External declarations for new functions in bgp_mpath.c * bgpd/bgp_route.c * bgp_info_free(): Free mpath memory when freeing path information * bgp_info_reap(): Dequeue path from multipath queue before deleting it * bgp_best_selection(): Calls bgp_info_mpath_update() with latest mp_list to mark-up rib table entry * bgp_vty_out_detail(): Add display of multipath flag for a path. Also display 'multipath' for bestpath if it is a multipath route * bgpd/bgp_route.h * struct bgp_info: Add pointer to bgp_info_mpath information * Add flags to mark a path as multipath (BGP_INFO_MULTIPATH) and to mark bestpath if multipath information has changed (BGP_INFO_MULTIPATH_CHG) * lib/memtypes.c * Add MTYPE_BGP_MPATH_INFO for allocating memory for bgp_info_mpath * tests/bgp_mpath_test.c * Add test case for bgp_info_mpath_update() and supporting functions
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

2009-08-28lib: if_lookup_by_name should be more robust to null argumentPaul Jakma
* if.c: (if_lookup_by_name) shouldn't crash just cause we got a NULL name
2009-07-28bgpd: start listener on first instanceStephen Hemminger
Start BGP listener only after first instance is started. This helps the security if BGP is not used but daemon is started. It also addresses some issues like MD5 not working on listener unless IPV6 configured (because listener was not in list); as well as compiler warnings. * bgp_network.c: (bgp_listener) listen socket creation consolidated here (bgp_socket) Use bgp_listener * bgpd.c: (bgp_get) call bgp_socket on creation of first struct bgp. (bgp_init) remove bgp_socket call. * memtypes.c: Add MTYPE_BGP_LISTENER
2009-07-19[bgpd] Stability fixes including bugs 397, 492Chris Caputo
I've spent the last several weeks working on stability fixes to bgpd. These patches fix all of the numerous crashes, assertion failures, memory leaks and memory stomping I could find. Valgrind was used extensively. Added new function bgp_exit() to help catch problems. If "debug bgp" is configured and bgpd exits with status of 0, statistics on remaining lib/memory.c allocations are printed to stderr. It is my hope that other developers will use this to stay on top of memory issues. Example questionable exit: bgpd: memstats: Current memory utilization in module LIB: bgpd: memstats: Link List : 6 bgpd: memstats: Link Node : 5 bgpd: memstats: Hash : 8 bgpd: memstats: Hash Bucket : 2 bgpd: memstats: Hash Index : 8 bgpd: memstats: Work queue : 3 bgpd: memstats: Work queue item : 2 bgpd: memstats: Work queue name string : 3 bgpd: memstats: Current memory utilization in module BGP: bgpd: memstats: BGP instance : 1 bgpd: memstats: BGP peer : 1 bgpd: memstats: BGP peer hostname : 1 bgpd: memstats: BGP attribute : 1 bgpd: memstats: BGP extra attributes : 1 bgpd: memstats: BGP aspath : 1 bgpd: memstats: BGP aspath str : 1 bgpd: memstats: BGP table : 24 bgpd: memstats: BGP node : 1 bgpd: memstats: BGP route : 1 bgpd: memstats: BGP synchronise : 8 bgpd: memstats: BGP Process queue : 1 bgpd: memstats: BGP node clear queue : 1 bgpd: memstats: NOTE: If configuration exists, utilization may be expected. Example clean exit: bgpd: memstats: No remaining tracked memory utilization. This patch fixes bug #397: "Invalid free in bgp_announce_check()". This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c: bgp_clear_route_node()". My apologies for not separating out these changes into individual patches. The complexity of doing so boggled what is left of my brain. I hope this is all still useful to the community. This code has been production tested, in non-route-server-client mode, on a linux 32-bit box and a 64-bit box. Release/reset functions, used by bgp_exit(), added to: bgpd/bgp_attr.c,h bgpd/bgp_community.c,h bgpd/bgp_dump.c,h bgpd/bgp_ecommunity.c,h bgpd/bgp_filter.c,h bgpd/bgp_nexthop.c,h bgpd/bgp_route.c,h lib/routemap.c,h File by file analysis: * bgpd/bgp_aspath.c: Prevent re-use of ashash after it is released. * bgpd/bgp_attr.c: #if removed uncalled cluster_dup(). * bgpd/bgp_clist.c,h: Allow community_list_terminate() to be called from bgp_exit(). * bgpd/bgp_filter.c: Fix aslist->name use without allocation check, and also fix memory leak. * bgpd/bgp_main.c: Created bgp_exit() exit routine. This function frees allocations made as part of bgpd initialization and, to some extent, configuration. If "debug bgp" is configured, memory stats are printed as described above. * bgpd/bgp_nexthop.c: zclient_new() already allocates stream for ibuf/obuf, so bgp_scan_init() shouldn't do it too. Also, made it so zlookup is global so bgp_exit() can use it. * bgpd/bgp_packet.c: bgp_capability_msg_parse() call to bgp_clear_route() adjusted to use new BGP_CLEAR_ROUTE_NORMAL flag. * bgpd/bgp_route.h: Correct reference counter "lock" to be signed. bgp_clear_route() now accepts a bgp_clear_route_type of either BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. * bgpd/bgp_route.c: - bgp_process_rsclient(): attr was being zero'ed and then bgp_attr_extra_free() was being called with it, even though it was never filled with valid data. - bgp_process_rsclient(): Make sure rsclient->group is not NULL before use. - bgp_processq_del(): Add call to bgp_table_unlock(). - bgp_process(): Add call to bgp_table_lock(). - bgp_update_rsclient(): memset clearing of new_attr not needed since declarationw with "= { 0 }" does it. memset was already commented out. - bgp_update_rsclient(): Fix screwed up misleading indentation. - bgp_withdraw_rsclient(): Fix screwed up misleading indentation. - bgp_clear_route_node(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_node_queue_del(): Add call to bgp_table_unlock() and also free struct bgp_clear_node_queue used for work item. - bgp_clear_node_complete(): Do peer_unlock() after BGP_EVENT_ADD() in case peer is released by peer_unlock() call. - bgp_clear_route_table(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. Use struct bgp_clear_node_queue to supply data to worker. Add call to bgp_table_lock(). - bgp_clear_route(): Add support for BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_route_all(): Use BGP_CLEAR_ROUTE_NORMAL. Bug 397 fixes: - bgp_default_originate() - bgp_announce_table() * bgpd/bgp_table.h: - struct bgp_table: Added reference count. Changed type of owner to be "struct peer *" rather than "void *". - struct bgp_node: Correct reference counter "lock" to be signed. * bgpd/bgp_table.c: - Added bgp_table reference counting. - bgp_table_free(): Fixed cleanup code. Call peer_unlock() on owner if set. - bgp_unlock_node(): Added assertion. - bgp_node_get(): Added call to bgp_lock_node() to code path that it was missing from. * bgpd/bgp_vty.c: - peer_rsclient_set_vty(): Call peer_lock() as part of peer assignment to owner. Handle failure gracefully. - peer_rsclient_unset_vty(): Add call to bgp_clear_route() with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. * bgpd/bgp_zebra.c: Made it so zclient is global so bgp_exit() can use it. * bgpd/bgpd.c: - peer_lock(): Allow to be called when status is "Deleted". - peer_deactivate(): Supply BGP_CLEAR_ROUTE_NORMAL purpose to bgp_clear_route() call. - peer_delete(): Common variable listnode pn. Fix bug in which rsclient was only dealt with if not part of a peer group. Call bgp_clear_route() for rsclient, if appropriate, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - peer_group_get(): Use XSTRDUP() instead of strdup() for conf->host. - peer_group_bind(): Call bgp_clear_route() for rsclient, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - bgp_create(): Use XSTRDUP() instead of strdup() for peer_self->host. - bgp_delete(): Delete peers before groups, rather than after. And then rather than deleting rsclients, verify that there are none at this point. - bgp_unlock(): Add assertion. - bgp_free(): Call bgp_table_finish() rather than doing XFREE() itself. * lib/command.c,h: Compiler warning fixes. Add cmd_terminate(). Fixed massive leak in install_element() in which cmd_make_descvec() was being called more than once for the same cmd->strvec/string/doc. * lib/log.c: Make closezlog() check fp before calling fclose(). * lib/memory.c: Catch when alloc count goes negative by using signed counts. Correct #endif comment. Add log_memstats_stderr(). * lib/memory.h: Add log_memstats_stderr(). * lib/thread.c: thread->funcname was being accessed in thread_call() after it had been freed. Rearranged things so that thread_call() frees funcname. Also made it so thread_master_free() cleans up cpu_record. * lib/vty.c,h: Use global command_cr. Add vty_terminate(). * lib/zclient.c,h: Re-enable zclient_free().
2009-07-16[lib] Fix IPv6 normalisationStephen Hemminger
