2006-08-27[lib] Bug #134: threads should be more robust against backward time jumpsPaul Jakma
2006-08-25 Paul Jakma <paul.jakma@sun.com> * thread.c: (general) Add support for monotonic clock, it may still jump forward by huge amounts, but should be immune to going backwards. Fixes bug #134. (quagga_gettimeofday_relative_adjust) helper, does what name says - adjusts gettimeofday based relative timer. (quagga_gettimeofday) helper to keep recent_time up to date. (quagga_get_relative) helper, update and getch the relative timer using gettimeofday(). POSIX CLOCK_MONOTONIC is also supported, but the code is not enabled yet nor tested. (quagga_real_stabilised) helper, retrieve absolute time but stabilised so as to never decrease. (quagga_gettime) Exported interface, analogous to POSIX clock_gettime() in interface, supporting several clocks. (quagga_time) Exported interface, analogous to traditional time(), will never decrease. (recent_relative_time) Convenience function to retrieve relative_time timeval, similar to existing recent_time absolute timeval, for when an approximately recent value will do. (remainder) Update to use above helpers. (thread_getrusage) Previously was a macro, but needs to be a function to twiddle with thread.c private stuff. * thread.c: Point the GETRUSAGE macro at previous function. Export quagga_gettime, quagga_time and recent_relative_time for general use.
2006-08-27[ospfd] draft-ogier-ospf-dbex-opt DB-exchange optimisationPaul Jakma
2006-08-03 Paul Jakma <paul.jakma@sun.com> * ospf_packet.c: (ospf_make_db_desc) Implement draft-ogier-ospf-dbex-opt DB-exchange optimisation.
2006-08-27[ospfd] Raise ExchangeDone earlier, avoid often needless round of DD packetsPaul Jakma
2006-08-03 Paul Jakma <paul.jakma@sun.com> * ospf_packet.c: (ospf_make_db_desc) Unset the DD More bit after constructing the packet, if appropriate. (ospf_db_desc_proc) Speed up Exchange, slave should raise ExchangeDone earlier, as RFC mandates, by forming its reply before deciding whether both sides are done, avoids a needless round of empty DD packet exchanges at the end of Exchange, hence speeding up ExchangeDone. (ospf_db_desc) use UNSET_FLAG macro.
2006-08-27[ospfd] trivial: consolidate LSDB delete code into single functionPaul Jakma
2006-08-04 Paul Jakma <paul.jakma@sun.com> * ospf_lsdb.c: (ospf_lsdb_delete_entry) new function, consolidate exact same functionality replicated in other functions. (ospf_lsdb_add) Strip out code by using ospf_lsdb_delete_entry. (ospf_lsdb_delete) ditto. (ospf_lsdb_delete_all) ditto.
2006-08-06[zebra] trivial: rtadv.h depends on interface.hPaul Jakma
2006-08-06 Paul Jakma <paul.jakma@sun.com> * rtadv.h: depends on interface.h, so should include it.
2006-08-06[zebra] fix inconsistencies in ifstat_update_* declarations and definitionsPaul Jakma
2006-08-06 Paul Jakma <paul.jakma@sun.com> * interface.h: (ifstat_update_proc) declaration should match ifstat_update_sysctl really, which is to not return status, as such status is not used anywhere. * if_{proc,sysctl}.c: Make ifstat_update_* definitions and return values consistent with each other and their declarations, ie: (void) (*) (void).
2006-08-06[bgpd] aspath_loop_check was broken, fix it and the aspath unit test code.Paul Jakma
2006-08-06 Paul Jakma <paul.jakma@sun.com> * bgp_aspath.c: (aspath_loop_check) Fix the typo-bug which essentially had disabled this check. Problem reported by Bartek Kania <mrbk@gnarf.org> in [quagga-users 7388]. * aspath_test.c: (validate) Fix the sense of the aspath_loop_check, which was the wrong way around and had actually been testing for aspath_loop_check to be buggy.
2006-08-04[zebra] IRDP: Move stream_free to where its created, probably fixing a leakPaul Jakma
2006-08-01 Paul Jakma <paul.jakma@sun.com> * irdp_main.c: (irdp_advertisement) free the stream here, when done, right under where it was allocated so it's blindingly obvious it's correct. This possibly fixes a very slow leak of streams in zebra. * irdp_packet.c: (send_packet) don't free the stream here as it's hard to tell if right, plus an error case seemed to returning before free anyway.
2006-08-04[zebra] add more stuff to misc_null to avoid compile breakagesPaul Jakma
2006-08-04 Paul Jakma <paul.jakma@sun.com> * misc_null.c: Add ifstat_update_sysctl, add another required header.
2006-08-02[testzebra] Patch to misc_null.c to get older gcc to recognize #pragma tricksAndrew J. Schorr
2006-08-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * misc_null.c: Must include header files to get older versions of gcc to process the #pragma statements properly.
2006-07-28[doc] Expand/cross-ref MD5 commands, tweak anchors to avoid added spacingPaul Jakma
2006-07-28 Paul Jakma <paul.jakma@sun.com> * main.texi: link-detect works on Solaris too. * ospfd.texi: Twiddle around with anchors a bit more. Clarify how setting MD5 auth by area and by interface interact, and add cross-references, as well as to the required command for setting key material.
2006-07-27[doc] minor tweaks, refine ospf redist,passive-inter, and abr-type helpPaul Jakma
2006-07-27 Paul Jakma <paul.jakma@sun.com> * quagga.texi: Remove unused index definitions Add an Index node - for the concept index. * routeserver.texi: Set exampleindex to 0, so the example configs with long IPv6 addresses stand better chance of fitting. * overview.texi: 'Supported RFC' -> 'Supported RFCs' Remove paragraph indentation - texinfo does that. Revise the supported OS list slightly. Remove the IPv6 stack list, seems very dated and irrelevant. Revise the 'How to get Quagga' section. * ospfd.texi: minor tweaks: add some anchors, fix some minor format issues. Revise the help for 'abr-type'. Note that text authentication is unwise, recc'd MD5. Add some extra text for redistribute and passive-interface, about how latter can substitute for redist connected.
2006-07-27[lib] remove autogenerated file, update .cvsignorePaul Jakma
2006-07-27[ospfd] Bug #288: do not change router ID unless forced by manual configurationAndrew J. Schorr
2006-07-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospfd.c: (ospf_router_id_update) Fix and document the algorithm for selecting the router ID: if there is not a statically configured ID, then stick to the most recent value to avoid disruptive changes. This should fix bug #288.
2006-07-27[zebra] Bug #268, Fix race between add/delete of routes, sanitise rib queueingPaul Jakma
2006-07-27 Paul Jakma <paul.jakma@sun.com> * rib.h: (struct rib) Add a route_node rn_status flag field, this has to be copied every time head RIB of a route_node changes. Remove the rib lock field, not needed - see below. Add a status field for RIB-private flags. * zebra_rib.c: Add a global for the workqueue hold time, useful for testing. (general) Fix for bug #268. Problem originally detailed by Simon Bryden in [quagga-dev 4001]. Essentially, add/delete of a RIB must happen /before/ the queue. Best-path selection (ie rib_process) and reaping of freed RIBs can then be done after queueing. Only the route_node is queued - no important RIB state (i.e. whether a RIB is to be deleted) is queued. (struct zebra_queue_node_t) Disappears, no longer need to track multiple things on the queue, only the route_node. (rib_{lock,unlock}) removed, RIBs no longer need to be refcounted, no longer queued. (rib_queue_qnode_del) Removed, deleted RIBs no longer deleted via the queue. (rib_queue_add_qnode) deleted (rib_queue_add) Only the route_node is queued for best-path selection, we can check whether it is already queued or not and avoid queueing same node twice - struct rib * argument is not needed. (rib_link/unlink) (un)link RIB from route_node. (rib_{add,del}node) Front-end to updates of a RIB. (rib_process) Reap any deleted RIBs via rib_unlink. Unset the route_node 'QUEUED' flag. (General) Remove calls to rib_queue_add where add/del node was called - not needed, update calls where not. Ignore RIB_ENTRY_REMOVEd ribs in loops through route_nodes
2006-07-27[zebra] Add 'debug zebra rib' commandsPaul Jakma
2006-07-27 Paul Jakma <paul.jakma@sun.com> * debug.{c,h}: Add 'debug zebra rib' and 'debug zebra rib queue'.
2006-07-27[zebra] Add test rig code, for testing the zebra RIBPaul Jakma
2006-07-27 Paul Jakma <paul.jakma@sun.com> * {ioctl,kernel}_null.c: Dummy/Null kernel method implementations, useful for testing zebra code that calls such methods. * {redistribute,misc}_null.c: Dummy/Null methods, as above. But for zclient, and for various misc functions. * test_main.c: Test harness for zebra, currently just to test the RIB. * Makefile.am: Build testzebra using above. * zebra_rib.c: Add a global for the workqueue hold time, useful for testing.
2006-07-27[bgpd] Potential bug#287 fix, peer_delete should NULL out freed buffersPaul Jakma
2006-07-27 Paul Jakma <paul.jakma@sun.com> * bgpd.c: (peer_delete) Ensure freed buffers can not be accidently reused. A potential fix for bug #287.
2006-07-27[vtysh] Never skip authentication, and add support for multiple -c commandsAndrew J. Schorr
2006-07-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * vtysh.1: Document new options -d and -E, and note that now multiple -c options may be supplied, with embedded linefeed now supported. In BUGS section, remove warning about vtysh causing a daemon to freeze, since this has been fixed. * vtysh_main.c: (usage) Add new -d and -E options. And note that -c can be used multiple times, possibly with embedded linefeeds. (longopts) Add new -d and -E options. (main) Add new -d and -E options, and create a linked list to support multiple -c options. Do not call vtysh_connect_all until after vtysh_read_config(config_default) and vtysh_auth have succeeded. This prevents the vtysh.conf file from configuring any daemons, and it ensures that authentication has been passed before we send any commands to any daemons. Call vtysh_connect_all with any daemon name supplied with -d. If it is unable to connect to any daemons, issue an error message and exit immediately. When used in -c mode, call vtysh_execute("enable") before executing the commands in order to match interactive behavior. And detect embedded linefeed chars in -c commands and break them up appropriately. * vtysh.h: (vtysh_connect_all) Fix proto to reflect new daemon_name argument, and that it now returns an integer -- the number of daemons to which we were able to connect. * vtysh.c: (vtysh_connect_all) Add a new daemon_name argument. If supplied, connect only to that daemon. And return the number of daemons to which we were able to connect. (vtysh_prompt): Performance enhancement -- make struct utsname static so we call uname to get the hostname only once.
2006-07-27[zebra] Connected routes must always be added to main tablePaul Jakma
2006-07-27 Rumen Svobodnikov <rumen@telecoms.bg> * connected.c: (connected_up_ipv4) interface connected routes always go to table main (or otherwise they cannot be used by linux as nexthops) * zserv.c: (zread_ipv4_add) send route to the correct routing table * zebra_rib.c (static_install_ipv4) set routing table
2006-07-26[ospfd] Allow ospf_lsa_unlock to NULL out callers' LSA pointers upon freePaul Jakma
2006-07-26 Paul Jakma <paul.jakma@sun.com> * ospf_lsa.{c,h}: (ospf_lsa_unlock) Change to take a double pointer to the LSA to be 'unlocked', so that, if the LSA is freed, the callers pointer to the LSA can be NULLed out, allowing any further use of that pointer to provoke a crash sooner rather than later. * ospf_*.c: (general) Adjust callers of ospf_lsa_unlock to match previous. Try annotate 'locking' somewhat to show which 'locks' are protecting what LSA reference, if not obvious. * ospf_opaque.c: (ospf_opaque_lsa_install) Trivial: remove useless goto, replace with return. * ospf_packet.c: (ospf_make_ls_ack) Trivial: merge two list loops, the dual-loop predated the delete-safe list-loop macro.
2006-07-25[ospfd] Additional NSM neighbour state change stats/informationPaul Jakma
2006-07-25 Paul Jakma <paul.jakma@sun.com> * ospf_neigbor.h: (struct ospf_neighbor) Add some additional neighbour state statistics fields, timestamps for progressive and regressive state changes, and pointer to event string for the latter state change. * ospf_nsm.c: (nsm_notice_state_change) Update new state changs history as required. * ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print out above new per-neighbour state change stats.
2006-07-25[lib] Optimise thread_call by caching pointer to thread history in the threadPaul Jakma
2006-07-25 Paul Jakma <paul.jakma@sun.com> * thread.h: (struct thread) Add a cache pointer to the struct cpu_thread_history, if it is known - saving hash lookup on each thread_call. * thread.c: (thread_call) Cache the pointer to the cpu_thread_history, so that future thread_calls of same thread can avoid the hash_lookup.
2006-07-11[ospfd] record timestamp and event of last NSM state change for neighbourPaul Jakma
2006-07-10 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (ospf_nsm_event) Record state change timestamp and event in nbr struct. * ospf_neighbor.h: (struct ospf_neighbor) Add fields to record timestamp of last NSM change and event. * ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print last state change timestamp and event, if available.
2006-07-11[ospfd] trivial: NSM AdjChange should print event, declutter core functionsPaul Jakma
2006-07-10 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (nsm_notice_state_changes) Move state change logging code to new func to declutter nsm_change_state and ospf_nsm_event. Log event with AdjChange, it's useful to know. (nsm_change_state) move adjchange and snmp logging to previous. (ospf_nsm_event) call nsm_notice_state_changes from here. Move the debug message to entry of function, so it gets out even if something goes wrong.
2006-07-11[ospfd] Remove nsm_reset_nbr and a bunch of useless NSM event/action functionsPaul Jakma
2006-07-10 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (nsm_change_state) call nsm_clear_adj for all adjacency losses, hence removing need for nsm_reset_nbr. (nsm_reset_nbr) kill it, clear_adj in previous does fine. (nsm_kill_nbr,nsm_start) remove nsm_reset_nbr call. (ospf_nsm_event) Allow NSM function to be NULL, this along with removal of nsm_reset_nbr, allows a bunch of now useless functiosn to be removed. Remove some useless variables. (nsm_ignore) now useless, remove. (nsm_bad_ls_req) ditto (nsm_seq_number_mismatch) " (nsm_oneway_received) " (nsm_inactivity_timer) " (nsm_ll_down) " (NSM) replace removed action functions with NULL.
2006-07-11[ospfd] Improve Hello NetworkMask mismatch warning to give more infoAndrew J. Schorr
2006-07-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_packet.c: (ospf_hello) Improve NetworkMask mismatch warning message to include interface name and conflicting prefix lengths.
2006-07-11[lib] Do not call vty_close in vty_log_out to avoid possible free memory accessAndrew J. Schorr
2006-07-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * vty.c: (vty_log_out) Do not call vty_close, because this could result in a parent function's accessing the freed memory. Instead, set status VTY_CLOSE and call shutdown(vty->fd, SHUT_RDWR). And add a comment on vty_close.
2006-07-10[lib] Fix infinite recursion for errors on vtys with terminal monitor enabledAndrew J. Schorr
2006-07-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * vty.c: (vty_log_out, vty_read, vty_flush, vtysh_flush, vtysh_read) After an I/O error, must set vty->monitor to 0 before calling zlog_warn, otherwise an infinite recursion could occur (since zlog_warn triggers a message to be written to the vty, and that in turn triggers another error message when it fails, etc.).
2006-07-10[ospfd] cleanup NSM neighbour delete through a new Deleted NSM statePaul Jakma
2006-07-07 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.h: Add a NSM_Deleted neighbour state, to act as dummy state indicating the neighbour is to be deleted. * ospf_nsm.c: (general) Use the NSM_Deleted state to delete neighbours, thus allowing code to be slightly more obvious in its flow. (nsm_timer_set) Add NSM_Deleted. Add another timer the code missed. (nsm_kill_nbr) No need for special case call to nsm_change_state anymore. Make the assert and error-handling for same case more readable (Andrew Schorr) Remove the call to ospf_nbr_delete, nsm_change_state can do this generally now via NSM_Deleted. (struct ... NSM) Add the dummy NSM_Deleted state, the 3 events that can lead to nsm_kill_nbr all now transition the NBR to NSM_Deleted and the general change_state function can be left to do the work. (ospf_nsm_event) Special casing of events and early-return can be removed now. On transition into Deleted, delete the nbr. * ospf_dump.c: (ospf_nsm_state_msg) Add Deleted.
2006-07-06[ospfd] early-return in nsm_event missed LLDown event, fixes use after freePaul Jakma
2006-07-06 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (ospf_nsm_event) LLDown event also results in nbr being deleted, requires early-return too. Likely explains some crash reports after interface events.
2006-07-04[doc] remove the auto-generated quagga.info file from CVSPaul Jakma
2006-07-04 Paul Jakma <paul.jakma@sun.com> * quagga.info: remove auto-generated file. It will still be present in dist tarballs, so shouldn't affect anyone but direct users of CVS. Required texinfo version should be widely available. * .cvsignore: ignore quagga.info
2006-07-04[ospfd] Apply some simplifications to ospf_nsm, from Andrew's suggestionsPaul Jakma
2006-07-04 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (general) Various small cleanups from Andrew's review of last set of patches. (nsm_timer_set) Loading, Full and default can share same code too. (nsm_should_adj) Can just be one big OR. (nsm_twoway_received) Collapse into return statement.
2006-07-04[ospfd] CID #13, dont try print out fields of LSA we know to be NULL.Paul Jakma
2006-07-02 Paul Jakma <paul.jakma@sun.com> * ospf_lsa.c: (ospf_translated_nssa_refresh) CID #13.
2006-07-04[ospfd] Clear adjacency state for NSM changes down to TwoWay/ExStartPaul Jakma
2006-07-02 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (nsm_clear_adj) clear adjacency related state for a neighbour, needed for some state changes from > ExStart down to ExStart or less, which need not go through nsm_reset_nbr. (nsm_reset_nbr) move code to former. Should be static. (ospf_nsm_event) Remove long dead code. Use nsm_clear_adj for state changes that take down adjacencies to TwoWay/ExStart. (nsm_kill_nbr) Oops, action function shouldn't try return 1 for error.
2006-07-04[ospfd] trivial cleanup of nsm_timer_setPaul Jakma
2006-07-02 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (nsm_timer_set) ls_req timer should be OFF in early states. Compact several identical sections. Set inactivity timer to OFF for Down, for documentary purposes.
2006-07-04[ospfd] Ensure NSM state functions can redirect next_state accidentlyPaul Jakma
2006-07-02 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (ospf_nsm_event) Don't allow action functions to change next_state if the NSM tables do not indicate next_state is conditional, log warning if one tries - existing code appears fine though.
2006-07-04[ospfd] consolidate adjacency check logicPaul Jakma
2006-07-02 Paul Jakma <paul.jakma@sun.com> * ospf_nsm.c: (nsm_should_adj) New function, just consolidate the 10.4 adjacency check from nsm_twoway_received/nsm_adj_ok. (nsm_twoway_received/nsm_adj_ok) Use former.
2006-07-03[debug] Debug messages to terminal vty sessions should include timestampsAndrew J. Schorr
2006-07-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * vty.c: (vty_log_out) Debug messages to terminal vty sessions should include timestamps.

2006-07-02 Paul Jakma <paul.jakma@sun.com> * rt_netlink.c: (netlink_interface_addr) Fix CID #104, can not proceed if addr is NULL. * zebra_rib.c: (static_add_ipv6) Fix CID #18, double check required arguments are supplied for the given nexthop type.
2006-07-02[bgpd] Fix crash on shutdown of peerPaul Jakma
2006-07-02 Paul Jakma <paul.jakma@sun.com> * bgp_fsm.c: (bgp_{stop,start}) Move clear/free of certain bits of state from stop to start, as they may be used via peer references on clearing queues..
2006-06-30[ripd] update to use auto-generated redistribute route-type defsPaul Jakma

2006-06-30[ospfd] Fix "show ip ospf neighbor A.B.C.D" to show all matchesAndrew J. Schorr
2006-06-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_vty.c: (show_ip_ospf_neighbor_id) Should show all instances of that neighbor (since it may appear on multiple interfaces) instead of bailing out after showing the first match.
2006-06-30[lib] Fix typo in cpp conditional for malloc.h includePaul Jakma
2006-06-28 Paul Jakma <paul.jakma@sun.com> * memory.c: Fix typo in cpp conditional around malloc.h, from comment in bug #269.
2006-06-30[ospfd] Avoid getting NSM stuck in ExStart by using local view of DR/BDRAndrew J. Schorr
2006-06-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * ospf_nsm.c: (nsm_twoway_received) When deciding whether to change from state Init to ExStart, the test for whether the neighboring router is DR or BDR should be against the local router's notion of DR/BDR, not the neighbor's view.

2006-06-28 Erik Muller <erikm@internap.com> * ospfd.h: Define 2 new struct ospf config flags: OSPF_LOG_ADJACENCY_CHANGES and OSPF_LOG_ADJACENCY_DETAIL * ospf_nsm.c (nsm_change_state): Log adjacency changes if requested. * ospf_vty.c (ospf_log_adjacency_changes): New command function to implement ospf subcommand "log-adjacency-changes [detail]". (no_ospf_log_adjacency_changes) Turn off log-adjacency-changes. (show_ip_ospf) Show whether adjacency changes are logged. (ospf_config_write) Add "log-adjacency-changes [detail]" to config. (ospf_vty_init) Add ospf_log_adjacency_changes and no_ospf_log_adjacency_changes. * ospfd.texi: Document new ospf router subcommand "log-adjacency-changes [detail]".

2006-06-27[lib] Remove numeric route-type argument in redistribute arg stringsPaul Jakma
2006-06-27 Paul Jakma <paul.jakma@sun.com> * route_types.awk: Remove setting the 'bare' numeric route type in redist strings.
2006-06-27[ospfd] Replace redistribution strings with new route_types.h defines.Paul Jakma
2006-05-23 Paul Jakma <paul.jakma@sun.com> * ospf_vty.c: (general) Replace in-place route redistribution command and help strings with the new auto-generated defines from lib/route_types.h
