* (general) Cleanup a some calls to XFREE,strdup, etc. to use the memory.h macros. * memtypes.c: Add MTYPE_IF_RMAP_NAME, MTYPE_PQUEUE, MTYPE_PQUEUE_DATA and MTYPE_HOST. * memtypes.h: update auto-built file. * if_rmap.c: Use MTYPE_IF_RMAP_NAME. * pqueue.c: Use the two MTYPE_PQUEUE mtypes for allocations.
2005-10-212005-10-20 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* sockopt.c: (setsockopt_multicast_ipv4) If IP_ADD_MEMBERSHIP fails with errno equal to EADDRINUSE, then issue an info message and try IP_DROP_MEMBERSHIP followed by IP_ADD_MEMBERSHIP.
2005-10-202005-10-20 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* memory.c: (show_memory_vty) Omit zero statistics. Print separators only if some non-zero stats have been printed in between. (show_separator) New function to print a separator. (show_memory_all) Keep track of whether a separator is needed between the different memory statistics groups.
2005-10-182005-10-18 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* memtypes.h: Add MTYPE_OSPF_VERTEX_PARENT (to match memtypes.c).
2005-10-182005-10-18 Paul Jakma <paul.jakma@sun.com>paul
* (general) SPF memory management cleanup and fix for rare double-free bug. * ospf_spf.h: (struct vertex_parent) New struct to hold parent specific data, eg the backlink and the parent vertex pointer, and point to the appropriate general struct vertex_nexthop. (struct vertex_nexthop) remove parent vertex pointer, so this struct can be shared across vertices. (struct vertex) rename list child to list children. Remove list of nexthops, replace with list of vertex_parents. * ospf_spf.c: (update_stat) trivial, remove cast from void *. (vertex_nexthop_new) remove init of parent - field is gone from struct vertex_nexthop. (ospf_canonical_nexthops_free) Remove the canonical vertex_nexthop memory objects. These are the vertex_nexthops attached to the first level of router vertices from the root. (vertex_parent_new) new function, create a vertex_parent. (vertex_parent_free) ditto, but free it. (ospf_vertex_new) Update to match changes to struct vertex. (ospf_vertex_free) Recursively free a struct vertex and its children. The parent list is used as a reference count. vertex_nexthops must be free seperately, if required. (ospf_vertex_dump) update to match struct vertex changes. Print out backlink of parents too. (ospf_vertex_add_parent) ditto. (ospf_lsa_has_link) update comment. (ospf_nexthop_add_unique) removed, not needed anymore. (ospf_nexthop_merge) ditto. (ospf_spf_consider_nexthop) renamed to ospf_spf_add_parent. Simplified to just create vertex_parent and add it. (ospf_spf_flush_parents) new function, flush out the parent list. (ospf_nexthop_calculation) Take the relevant route_lsa_link as an argument, which simplifies things and removes the need for the hack in ospf_nexthop_add_unique - ospf_spf_next already knew exactly which link the cost calculated was for. Update to match struct vertex changes too. (ospf_spf_next) Don't create a vertex for W unnecessarily, if it's there's a vertex already created for W, use it, and hence there's no need to free it either. Update some manipulation/comparisons of distance to match. Flush the parent list if a lower cost path is found. (ospf_spf_route_free) unused, removed. (ospf_spf_dump) match the struct vertex changes, and dump the ifname if possible. (ospf_spf_calculate) At end of SPF, free the canonical nexthops and call ospf_vertex_free on the root vertex to free the entire tree. * ospf_interface.c: (ospf_vl_set_params) match struct vertex changes. * ospf_route.c: (ospf_intra_route_add) ditto (ospf_route_copy_nexthops_from_vertex) ditto * memtypes.c: (memory_list_ospf) Add MTYPE_OSPF_VERTEX_PARENT.

* zebra.h: Declare new functions zebra_route_string() and zebra_route_char(). * log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New functions to map zebra route numbers to strings. * zebra_vty.c: (route_type_str) Remove obsolete function: use new library function zebra_route_string() instead. Note that there are a few differences: for IPv6 routes, we now get "ripng" and "ospf6" instead of the old behavior ("rip" and "ospf"). (route_type_char) Remove obsolete function: ues new library function zebra_route_char() instead. Note that there is one difference: the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route, whereas the new one returns 'X'. (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace route_type_str() with zebra_route_string(). (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char() with zebra_route_char(). * bgp_vty.c: (bgp_config_write_redistribute) Use new library function zebra_route_string instead of a local hard-coded table. * ospf6_asbr.c: Remove local hard-coded tables zroute_name and zroute_abname. Change the ZROUTE_NAME macro to use new library function zebra_route_string(). Remove the ZROUTE_ABNAME macro. (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with a call to zebra_route_char(), and be sure to fix the format string, since we now have a char instead of a char *. * ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and zebra_route_abname. Note that the zebra_route_name[] table contained mixed-case strings, whereas the zebra_route_string() function returns lower-case strings. (ospf6_zebra_read_ipv6): Change debug message to use new library function zebra_route_string() instead of zebra_route_name[]. (show_zebra): Use new library function zebra_route_string() instead of zebra_route_name[]. * ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto. (ospf_redist_string) New function implemented using new library function zebra_route_string(). Note that there are a few differences in the output that will result: the new function returns strings that are lower-case, whereas the old table was mixed case. Also, the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the new function returns "ospf6". * ospfd.h: Remove extern struct message ospf_redistributed_proto[], and add extern const char *ospf_redist_string(u_int route_type) instead. * ospf_asbr.c: (ospf_external_info_add) In two messages, use ospf_redist_string instead of LOOKUP(ospf_redistributed_proto). * ospf_vty.c: Remove local hard-coded table distribute_str. (config_write_ospf_redistribute,config_write_ospf_distribute): Use new library function zebra_route_string() instead of distribute_str[]. * ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset, ospf_redistribute_default_set,ospf_redistribute_check) In debug messages, use ospf_redist_string() instead of LOOKUP(ospf_redistributed_proto). * rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded table str[]. Replace str[] with calls to new library function zebra_route_string(). * ripd.c: Remove local hard-coded table route_info[]. (show_ip_rip) Replace uses of str[] with calls to new library functions zebra_route_char and zebra_route_string. * ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded table str[]. Replace str[i] with new library function zebra_route_string(i). * ripngd.c: Remove local hard-coded table route_info[]. (show_ipv6_ripng) Use new library function zebra_route_char() instead of table route_info[].

* lib/smux.[ch]: allow to retreive global OID (identified by <0 namelen). * ospf_ism.c: generate SNMP traps on Interface state change * ospf_nsm.c: generate SNMP traps on Neighbour state change * ospf_snmp.[ch]: support for SNMP traps for interface and neighbours.
2005-09-292005-09-29 Paul Jakma <paul.jakma@sun.com>paul
* configure.ac: Add the test for Solaris least-privileges. Set defines for whether capabilities are supported and whether of the linux or solaris variety. Add missing-prototypes, missing-declarations, char-subscripts and cast-qual warnings to default cflags, cause Hasso enjoys warnings, and we really should clean the remaining ones up. (ie isisd..). * (*/*main.c) Update the zebra_capabilities_t arrays in the various daemons to match the changes made in lib/privs.h. * zebra.h: Solaris capabilities requires priv.h to be included. * privs.{c,h}: Add support for Solaris Least-Privileges. privs.h: Reduce some of the abstract capabilities, which do not have rough equivalents on both systems. Rename the net related caps to _NET, as they should have been in first place. (zprivs_terminate) should take the zebra_privs_t as argument so that it can update change pointer. Add an additional privilege state, ZPRIVS_UNKNOWN. * privs.c: (various capability functions) Add Solaris privileges variants. (zprivs_state) Use privs.c specific generic types to represent various capability/privilege related types, so that each can be typedef'd as appropriate on each platform. (zprivs_null_state) static added, to hold the state the null method should report (should be raised by default, and LOWERED if zprivs_terminate has been called) (zprivs_state_null) Report back the zprivs_null_state. (cap_map) Make it able to map abstract capability to multiple system capabilities. (zcaps2sys) Map to abstract capabilities to multiple system privileges/capabilities. (zprivs_init) move capability related init to seperate function, zprivs_caps_init. (zprivs_terminate) ditto, moved to zprivs_caps_terminate. Set the change_state callback to the NULL state, so the user can continue to run and use the callbacks.

* lib/filer.c: show protocol name in filter_show() * lib/plist.c: show protocol name in vty_show_prefix_entry() * routemap.c: show protocol name in vty_show_route_map_entry() * lib/vty.c: in vty_command(), show protocol name if command unknown * zebra/zserv.c: Always provide distance fo route add * ripd/rip_snmp.c: rip2IfConfReceive() sends values in conformance with RFC. Also PeerDomain is now set to a STRING type. * ripd/ripd.h: rip_redistribute_add() API includes metric and distance * ripd/ripd.c: rip_redistribute_add() API i.e. stores metric and distance Now allows a RIP-route to overcome a redistributed route coming from a protocol with worse (higher) administrative distance Metrics from redistribution are shown in show ip rip * ripd/rip_zebra.c: adapt to the rip_redistribute_add() API, i.e. provide distance and metric * ripd/rip_interface.c: adapt to the rip_redistribute_add() API * ripd/rip_routemap.c: no RMAP_COMPILE_ERROR on (metric > 16) usage rather a CMD_WARNING, because set metric ius shared with other protocols using larger values (such as OSPF) The match metric action takes first external metric if present (from redistribution) then RIP metric.

* lib/md5-gnu.h: removed * lib/md5.h: replaces md5-gnu.h * lib/Makefile.am: use correct md5.h * lib/md5.c: import from WIDE * ospfd/ospf_packet.c: use new md5 API * ripd/ripd.c: use new md5 API
2005-09-212005-09-21 Paul Jakma <paul.jakma@sun.com>paul
* memtypes.{c,h}: Add MTYPE_AS_SEG_DATA.
2005-09-19 * configure.ac: Test existance of strndup.hasso
* lib/str.[ch]: Add strndup() from glibc.
2005-09-052005-09-05 Paul Jakma <paul.jakma@sun.com>paul
* command.c: (install_element) be more robust. Eg, cmd_init need not have been called, some applications may use other library subsystems, which call install_element, without the application wanting commands and hence not calling cmd_init.
2005-08-222005-08-22 Hugo Santos <hsantos@av.it.pt>paul
* command.h: (enum node_type) Add BGP_IPV6M_NODE * command.c: (node_parent) Handle BGP_IPV6M_NODE node (config_exit, config_end) ditto * vty.c: (vty_end_config) Handle BGP_IPV6M_NODE node
2005-08-102005-08-10 Greg Troxel <gdt@fnord.ir.bbn.com>gdt
* getopt.h: Don't declare getopt (rather than getopt_long), since quagga doesn't need it. * getopt.c (getopt): Don't define getopt. Fixes build breakage on NetBSD, and seems likely to work on most platforms since it avoids the entire issue of system getopt declarations and whether they conform to POSIX.2. Note that this change doesn't address system getopt_long declarations, but also doesn't change anything about getopt_long.
2005-07-262005-07-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* prefix.c: (prefix_ipv4_new, prefix_ipv6_new): Call prefix_new to allocate the memory to make sure that all struct prefix pointers point to objects of the same length (avoids memory overruns on struct prefix assignments). (prefix_ipv4_free, prefix_ipv6_free): Simply call prefix_free. It is interesting to note that these functions are never actually called anywhere in the code. Instead prefix_free was already being called directly, despite the previous MTYPE incompatibility. [backport candidate]
2005-07-262005-07-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* prefix.c: (ip_masklen) While loop should test that 'pnt' pointer is in range before dereferencing it. [backport candidate]
2005-06-242005-06-24 Pawel Worach <pawel.worach@gmail.com>paul
* getopt.h: add further tests for full getopt declaration on various systems.
2005-06-182005-06-18 Paul Jakma <paul.jakma@sun.com>paul
* memtypes.h: update autobuilt file to match memtypes.c changes
2005-06-012005-06-01 Paul Jakma <paul.jakma@sun.com>paul
* bgpd/(general) refcount struct peer and bgp_info, hence allowing us add work_queues for bgp_process. * bgpd/bgp_route.h: (struct bgp_info) Add 'lock' field for refcount. Add bgp_info_{lock,unlock} helper functions. Add bgp_info_{add,delete} helpers, to remove need for users managing locking/freeing of bgp_info and bgp_node's. * bgpd/bgp_table.h: (struct bgp_node) Add a flags field, and BGP_NODE_PROCESS_SCHEDULED to merge redundant processing of nodes. * bgpd/bgp_fsm.h: Make the ON/OFF/ADD/REMOVE macros lock and unlock peer reference as appropriate. * bgpd/bgp_damp.c: Remove its internal prototypes for bgp_info_delete/free. Just use bgp_info_delete. * bgpd/bgpd.h: (struct bgp_master) Add work_queue pointers. (struct peer) Add reference count 'lock' (peer_lock,peer_unlock) New helpers to take/release reference on struct peer. * bgpd/bgp_advertise.c: (general) Add peer and bgp_info refcounting and balance how references are taken and released. (bgp_advertise_free) release bgp_info reference, if appropriate (bgp_adj_out_free) unlock peer (bgp_advertise_clean) leave the adv references alone, or else call bgp_advertise_free cant unlock them. (bgp_adj_out_set) lock the peer on new adj's, leave the reference alone otherwise. lock the new bgp_info reference. (bgp_adj_in_set) lock the peer reference (bgp_adj_in_remove) and unlock it here (bgp_sync_delete) make hash_free on peer conditional, just in case. * bgpd/bgp_fsm.c: (general) document that the timers depend on bgp_event to release a peer reference. (bgp_fsm_change_status) moved up the file, unchanged. (bgp_stop) Decrement peer lock as many times as cancel_event canceled - shouldnt be needed but just in case. stream_fifo_clean of obuf made conditional, just in case. (bgp_event) always unlock the peer, regardless of return value of bgp_fsm_change_status. * bgpd/bgp_packet.c: (general) change several bgp_stop's to BGP_EVENT's. (bgp_read) Add a mysterious extra peer_unlock for ACCEPT_PEERs along with a comment on it. * bgpd/bgp_route.c: (general) Add refcounting of bgp_info, cleanup some of the resource management around bgp_info. Refcount peer. Add workqueues for bgp_process and clear_table. (bgp_info_new) make static (bgp_info_free) Ditto, and unlock the peer reference. (bgp_info_lock,bgp_info_unlock) new exported functions (bgp_info_add) Add a bgp_info to a bgp_node in correct fashion, taking care of reference counts. (bgp_info_delete) do the opposite of bgp_info_add. (bgp_process_rsclient) Converted into a work_queue work function. (bgp_process_main) ditto. (bgp_processq_del) process work queue item deconstructor (bgp_process_queue_init) process work queue init (bgp_process) call init function if required, set up queue item and add to queue, rather than calling process functions directly. (bgp_rib_remove) let bgp_info_delete manage bgp_info refcounts (bgp_rib_withdraw) ditto (bgp_update_rsclient) let bgp_info_add manage refcounts (bgp_update_main) ditto (bgp_clear_route_node) clear_node_queue work function, does per-node aspects of what bgp_clear_route_table did previously (bgp_clear_node_queue_del) clear_node_queue item delete function (bgp_clear_node_complete) clear_node_queue completion function, it unplugs the process queues, which have to be blocked while clear_node_queue is being processed to prevent a race. (bgp_clear_node_queue_init) init function for clear_node_queue work queues (bgp_clear_route_table) Sets up items onto a workqueue now, rather than clearing each node directly. Plugs both process queues to avoid potential race. (bgp_static_withdraw_rsclient) let bgp_info_{add,delete} manage bgp_info refcounts. (bgp_static_update_rsclient) ditto (bgp_static_update_main) ditto (bgp_static_update_vpnv4) ditto, remove unneeded cast. (bgp_static_withdraw) see bgp_static_withdraw_rsclient (bgp_static_withdraw_vpnv4) ditto (bgp_aggregate_{route,add,delete}) ditto (bgp_redistribute_{add,delete,withdraw}) ditto * bgpd/bgp_vty.c: (peer_rsclient_set_vty) lock rsclient list peer reference (peer_rsclient_unset_vty) ditto, but unlock same reference * bgpd/bgpd.c: (peer_free) handle frees of info to be kept for lifetime of struct peer. (peer_lock,peer_unlock) peer refcount helpers (peer_new) add initial refcounts (peer_create,peer_create_accept) lock peer as appropriate (peer_delete) unlock as appropriate, move out some free's to peer_free.

(bgp_terminate) free workqueues too. * lib/memtypes.c: Add MTYPE_BGP_PROCESS_QUEUE and MTYPE_BGP_CLEAR_NODE_QUEUE
2005-05-242005-05-24 Paul Jakma <paul@dishone.st>paul
* memtypes.h: update this auto-built file. (maybe we should just remove it, is GNU awk a terrible dependency to have?)
2005-05-232005-05-23 Paul Jakma <paul@dishone.st>paul
* workqueue.h: Add a WQ_QUEUE_BLOCKED item_status return code, to allow a queue function to indicate the queue is not ready/blocked - rather than any problem with the item at hand. Add a notion of being able to 'plug' and 'unplug' a queue. Add helpers to plug/unplug a queue. Add a completion callback, to be called when a queue is emptied. * workqueue.c: (work_queue_new) remove useless list_free. (work_queue_schedule) new internal helper function to schedule queue, if appropriate. (work_queue_add) use work_queue_schedule (show_work_queues) Print 'P' if queue is plugged. (work_queue_plug) new API function, plug a queue - ie prevent it from 'drained' / processed / scheduled. (work_queue_unplug) unplug a queue, allowing it to be drained / scheduled / processed again. (work_queue_run) Add support for WQ_QUEUE_BLOCKED. Add comment for RETRY_NOW case. Make hysteris more aggresive in ramping up granularity, improves performance significantly. Add support for calling completion callback when queue is emptied, possibly useful for knowing when to unplug a queue.
2005-05-232005-05-23 Paul Jakma <paul@dishone.st>paul
* routemap.c: (rmap_onmatch_goto) fix crash if 'continue' command is used, which does not supply an argv[0]. this is a backport candidate /iff/ the trailing ; is removed from VTY_GET_INTEGER_RANGE * vty.h: fix the VTY_GET macros, do {..} while(0) so they have correct function like syntax in usage.
2005-05-232005-05-23 Paul Jakma <paul@dishone.st>paul
* memtypes.awk: use character classes, which work correctly in all LC_COLLATE environments, unlike A-Z, which doesnt work in eg estonian collate order. Reported by Hasso.
2005-05-192005-05-19 Paul Jakma <paul@dishone.st>paul
* memtypes.c: (memory_list_bgp) add MTYPE_BGP_PEER_HOST
2005-05-192005-05-19 Paul Jakma <paul@dishone.st>paul
* sockunion.c: (sockunion_getsockname) use MTYPE_SOCKUNION, not TMP (sockunion_getpeername) ditto
2005-05-192005-05-19 Paul Jakma <paul@dishone.st>paul
* thread.c: (thread_cancel_event) the number of pending events cancelled is potentially useful information, dont throw it away, pass it back to the caller.
2005-05-152005-05-15 Paul Jakma <paul@dishone.st>paul
* getopt.h: It's not just __GNU_LIBRARY__ which defines getopt, eg __EXTENSIONS__ does too on SunOS. It still seems awfully fragile though. * getopt.c: include zebra.h after config.h, before including getopt.h so that things at least are consistent.. * getopt1.c: ditto
2005-05-072005-05-07 Yar Tikhiy <yar@comp.chem.msu.su>paul
* configure.ac: Check for OSes which support passing ifindex in struct ip_mreq. * lib/sockopt.c: Add support for BSD style ifindex in ip_mreq. * ospfd/ospf_network.c: Log ifindex on multicast membership leave/join events.
2005-05-062005-05-06 Paul Jakma <paul@dishone.st>paul
* (general) extern and static'ification of functions in code and header. Cleanup any definitions with unspecified arguments. Add casts for callback assignments where the callback is defined, typically, as passing void *, but the function being assigned has some other pointer type defined as its argument, as gcc complains about casts from void * to X* via function arguments. Fix some old K&R style function argument definitions. Add noreturn gcc attribute to some functions, as appropriate. Add unused gcc attribute to some functions (eg ones meant to help while debugging) Add guard defines to headers which were missing them. * command.c: (install_node) add const qualifier, still doesnt shut up the warning though, because of the double pointer. (cmp_node) ditto * keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived fromn vty.h ones to fix some of the (long) < 0 warnings. * thread.c: (various) use thread_empty (cpu_record_hash_key) should cast to uintptr_t, a stdint.h type * vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they removed from ospfd/ospf_vty.h * zebra.h: Move definition of ZEBRA_PORT to here, to remove dependence of lib on zebra/zserv.h
2005-05-06 * sockunion.c: Fix warning message.hasso
2005-05-032005-05-03 Paul Jakma <paul@dishone.st>paul
* stream.h: Add comment about the special zero-ing ability of stream_put. (stream_recvmsg, stream_write) should return ssize_t and size_t respectively. Should both be extern linkage. (stream_recvfrom) Stream aware wrapper around recvfrom, in style of stream_read_try. * stream.c: (stream_recvfrom) new function, wrapper around recvfrom. (stream_recvmsg, stream_write) ssize_t and size_t return values
2005-04-282005-04-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
Add wall-clock timing statistics to 'show thread cpu' output. * thread.h: Define struct rusage_t to contain wall-clock time and cpu time. Change GETRUSAGE macro to collect both pieces of data. Make appropriate changes to struct cpu_thread_history to track CPU time and real time. Change proto for thread_consumed_time to return real and cpu time elapsed. And declare a new global variable 'struct timeval recent_time'. * thread.c (struct timeval recent_time): New global timestamp variable. (timeval_adjust): If timeout is negative, set to 0 (not 10 microseconds). And remove upper bound of 1,000,000 seconds, since this does not seem to make any sense (and it breaks funcname_thread_add_timer_timeval). (timeval_cmp): Should return long, not int. (vty_out_cpu_thread_history): Show CPU time and real time. (cpu_record_hash_print): Calculate totals for CPU and real time. (cpu_record_print): Change 'show thread cpu' title to show CPU and real time. (thread_timer_remain_second): Put current time in global recent_time. (funcname_thread_add_timer_timeval): Fix assert. Replace 2-case switch assignment with a ternary expression. Use global recent_time variable. Fix use of timeval_adjust (previously, the value was not actually being adjusted). (thread_cancel): Add missing "break" statement in case THREAD_BACKGROUND. (thread_timer_wait): Use global recent_time value instead of calling gettimeofday. And there's no need to check for negative timeouts, since timeval_subtract already sets these to zero. (thread_timer_process): Timers are sorted, so bail out once we encounter a timer that has not yet popped. And remove some extraneous asserts. (thread_fetch): Do not process foreground timers before calling select. Instead, add them to the ready list just after the select. Also, no need to maintain a count of the number of ready threads, since we don't care how many there are, just whether there's one at the head of the ready list (which is easily checked). Stick current time in global variable recent_time to reduce the number of calls to gettimeofday. Tighten logic for calculating the select timeout. (thread_consumed_time): Now returns real time and puts the elapsed cpu time in an additional argument. (thread_should_yield): Use real (wall-clock) time to decide whether to yield. (thread_call): Maintain CPU and real time statistics. * vty.c (vty_command): For slow commands, show real and cpu time.
2005-04-272005-04-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* workqueue.c (show_work_queues): Remove unused gettimeofday call.
2005-04-272005-04-27 Paul Jakma <paul.jakma@sun.com>paul
* memory.h: memtypes is built source, default includes points to top_builddir, so we should refer to lib/memtypes.h
2005-04-272005-04-27 Paul Jakma <paul.jakma@sun.com>paul
* workqueue.h: (struct work_queue_item) change retry_count to ran, its a count of number item has been run. * workqueue.c: (show_work_queues) Fix formating of slightly bugfix: fix SIGFPE if wq->runs is 0. (work_queue_run) retry logic was slightly wrong. cycles.best is 0 initialy, granularity is 1, so update best if cycles >= granularity, not just >.

* buffer.c (buffer_write): Comment out call to buffer_flush_available. This should speed up buffering at the expense of a possible increase in latency in flushing the data if inside a long-running thread.

* thread.h: Fix type for struct thread_master add_type: should be unsigned char. Also, add some documentation of thread_add_background args. And remove extraneous declaration of show_thread_work_queues_cmd.
2005-04-222005-04-22 Paul Jakma <paul.jakma@sun.com>paul
* memory.h: Move include of memtypes.h to after the definition of struct memory_list, gcc 4.0 doesn't like arrays of incomplete types.

* thread.h: Add background thread type and thread_add_background macro and accompanying funcname_... function. export thread_should_yield, background threads can use it. Lower thread yield time to 10ms, 100ms is noticeable lag and a thread would only be /starting/ to finish sometime afterward. * thread.c: (general) Add background thread type and schedule nearly all thread types through the ready list for fairness. (timeval_adjust) static qualifier missing (vty_out_cpu_thread_history) add support for printout of background threads (show_thread_cpu) ditto. (thread_master_debug) add debug of background list (thread_master_create) fixup long line (thread_add_unuse) add asserts for required state. (thread_master_free) free background thread list (funcname_thread_add_timer_timeval) make generic, able to support arbitrary timer-like thread types. (funcname_thread_add_timer) pass thread type to .._add_timer_timeval (funcname_thread_add_timer_msec) ditto (funcname_thread_add_background) Add a background thread, with an optional millisecond delay factor, using .._add_timer_timeval. (thread_cancel) Add background thread type. Move the thread_list_delete common to all cases to bottom of function, after the switch statement.. (thread_cancel_event) indent (thread_timer_wait) Static qualifier, and make it able to cope with arbitrary timer-like thread lists, so its of use to background threads too. (thread_process_fd) static qualifier. Again, make it take a list reference rather than thread_master. Fix indentation. (thread_timer_process) Check for ready timer-like threads in the given list and move them on to the ready list - code originally embedded in thread_fetch. (thread_fetch) Schedule all threads, other than events, through the ready list, to ensure fairness. Timer readying code moved to thread_timer_process so it can be reused for background threads. Remove the unneeded quagga_sigevent_process, as pointed out by John Lin <john.ch.lin@gmail.com>. (thread_should_yield) make this available.

* configure.ac: Added AC_ARG_ENABLE(time-check). By default, warning messages will now be printed for threads or commands that take longer than 5 seconds, but this configure argument can be used to disable the checks or change the threshold. * thread.h (thread_consumed_time): Declare new function to calculate elapsed microseconds. * thread.c (thread_consumed_time): Must be global not static so we can call it from lib/vty.c:vty_command. (thread_should_yield): Surround with `#if 0' to make clear that this function is not currently being used anywhere. (thread_call): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the thread takes more than CONSUMED_TIME_CHECK microseconds. * vty.c (vty_command): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the command takes more than CONSUMED_TIME_CHECK microseconds.

* memtypes.c: the comment about use of comments in the comments headers was causing comment within comment warnings from compiler * memtypes.awk: Add extensive comments on the file format for memtypes.c. tighten the pattern for the MTYPE matching action (suggestion from Andrew) and tighten which field we try the match on.
2005-04-152005-04-15 Paul Jakma <paul@dishone.st>paul
* Makefile.am: memtypes.awk is gawk dependent, use the GAWK automake var. * memtypes.h: New file, auto-generated, checked in for convenience.
2005-04-152005-04-15 Paul Jakma <paul@dishone.st>paul
* memtypes.c: The new, unified location for memory type definitions. The memtype enum and declarations for memory_lists are built from this automatically and put into memtypes.h. * memtypes.awk: New script to generate memtypes.h from memtypes.c * memory.h: Finally, the enum can banished! * memory.c: Finally, the seperate mtype memory_list definitions can be banished! (log_memstats) Increase width of fields (show_memory_zebra_cmd) display zebra specific memory types. Increase width of fields. * Makefile.am: Add memtypes.{c,h}, add BUILT_SOURCES for memtypes.h Add a rule to build memtypes.h using memtypes.awk. Add memtypes.awk to EXTRA_DIST.

Implement non-blocking zclient I/O with buffering. * zclient.h (struct zclient): Add two fields to support non-blocking I/O: struct buffer *wb, and struct thread *t_write. (zclient_free): Remove function. (zebra_redistribute_send): Change 2nd arg from socket fd to struct zclient * (needed to support non-blocking I/O and buffering). (zclient_send_message): New function to send an arbitrary message with non-blocking I/O. * zclient.c (zclient_new): Create write buffer. (zclient_free): Remove unused function. (zclient_stop): Must cancel new t_write thread. Also, reset all buffers: ibuf, obuf, and wb. (zclient_failed): New helper function for typical error handling. (zclient_flush_data): New thread to flush queued data. (zclient_send_message): New function to send the message in zclient->obuf to zebra using non-blocking I/O and buffering. (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use new zclient_send_message function instead of calling writen. (zclient_start): Set socket non-blocking. Also, change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. (zebra_redistribute_send): Change 2nd arg to struct zclient *. Can now use zclient->obuf to assemble the message instead of allocating a temporary stream. And call zclient_send_message to send the message instead of writen. (zclient_read): Convert to support non-blocking I/O by using stream_read_try instead of deprecated stream_read. (zclient_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. * rip_zebra.c (rip_redistribute_set, rip_redistribute_unset, rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset): The 2nd arg to zebra_redistribute_send is now zclient instead of zclient->sock. * isis_zebra.h (isis_zebra_finish): Remove declaration of unused function. * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message to send the message to zebra instead of calling writen directly, since zclient_send_message understands non-blocking I/O and will manage the buffer queue appropriately. (isis_zebra_finish): Remove unused function, particularly since the zclient_free function has been removed.
