+ initial edition of meta-queue for RIB updates processing (bug #431)

[jleu-quagga.git] / lib / ChangeLog

2008-06-02 Denis Ovsienko

        * workqueue.[ch]: completely drop WQ_AIM_HEAD flag and
          work_queue_aim_head() function, they aren't needed any more
          with the new meta queue structure; (work_queue_run) don't
          increment the counter on work item requeueing

2008-02-28 Paul Jakma <paul.jakma@sun.com>

        * log.c: (mes_lookup) Sowmini Varadhan diagnosed a problem where
          this function can cause a NULL dereference, on lookups for unknown
          indices, or messages with NULL strings. Can occur, e.g., debug
          logging code when processing received messages. Fixed to accept a
          pointer to a default string to be used if there is no match.
        * log.h: LOOKUP adjusted to match

2008-02-28 Paul Jakma <paul.jakma@sun.com>

        * linklist.c: This implementation expects that the data pointer not
          be null, e.g. listgetdata() asserts this. The list add methods
          don't apply the same sanity check.

          Noted by Jim Carlson in bug #437.

2008-01-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: Revert previous change, no need to include <net/if_media.h>
          here.

2008-01-10 Ingo Flaschberger <if@xip.at>

        * zebra.h: If HAVE_BSD_LINK_DETECT is defined, include <net/if_media.h>.

2008-01-08 Pavol Rusnak <prusnak@suse.cz>

        * memory.c: (mtype_memstr) Fix accidental shift past width of type,
          constant should have been forced to UL, rather than being left to
          default to int.

2007-11-12 Denis Ovsienko

        * linklist.c: (listnode_add_after) Don't forget to increment list
          items counter.
        * workqueue.h: Changed working queue flags from enum into integer
          and introduced WQ_AIM_HEAD flag to indicate our will to insert
          new data before the list head.
        * workqueue.[ch]: (work_queue_schedule, show_work_queues,
          work_queue_plug, work_queue_unplug) Adjust to the new flags style.
        * workqueue.[ch]: (work_queue_aim_head) new function to control the
          WQ_AIM_HEAD flag
        * workqueue.[ch]: (work_queue_new) Explicitly set both WQ flags
          during new WQ initialization.
        * workqueue.[ch]: (work_queue_add) If WQ_AIM_HEAD indicates a need
          to place the new data into list head, do it.

2007-10-22 Lorenzo Colitti <lorenzo@colitti.com>

        * smux.c: (smux_stop) Avoid cancelling a defunct thread pointer
          (smux_start) Stop smux before trying to start it, possibly again.

2007-10-04 Denis Ovsienko

        * pid_output.c: (pid_output) stop using LOGFILE_MASK
          (0600 by default), introduce and use PIDFILE_MASK (0644)
          instead.

2007-09-18  Paul Jakma <paul.jakma@sun.com>

        * privs.c: definition of ZCAP_NET_ADMIN on Solaris should
          be PRIV_SYS_IP_CONFIG, when that's available. Thus allowing
          Quagga to work with in Solaris zones with exclusive IP
          instances.

2007-08-21 Denis Ovsienko

        * sockopt.[ch]: (setsockopt_so_sendbuf, getsockopt_so_sendbuf):
          new functions to adjust ospfd working socket.

2007-08-13 Denis Ovsienko

        * zebra.h: introduce ZEBRA_ERR_KERNEL and ZEBRA_ERR_NOERROR

2007-07-06 Atis Elsts <atis@mikrotik.com>

        * pqueue.{c,h}: Export trickle_up

2007-07-26  Paul Jakma <paul.jakma@sun.com>

        * log.c: (mes_lookup) warning about code not being in same-number
          array slot should be debug, not warning. E.g. BGP has several
          discontigious number spaces, allocating from different parts of a
          space is not uncommon (e.g. IANA assigned versus vendor-assigned
          code points in some number space).
          
2007-07-06 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sockopt.{c,h}: (setsockopt_multicast_ipv4) Add some comments about
          the arguments.

2007-06-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: On linux, we seem to need to include <linux/types.h> before
          <sys/sysctl.h>, otherwise we get isisd compilation errors about
          __be16 not being defined.

2007-05-10 Paul Jakma <paul.jakma@sun.com>

        * zebra.h: Don't try define _GNU_SOURCE, autoconf should do it.

2007-05-03 Paul Jakma <paul.jakma@sun.com>

        * memtypes.c: Add MTYPE_ATTR_EXTRA and MTYPE_BGP_ROUTE_EXTRA

2007-05-01 David L Stevens <dlstevens@us.ibm.com>

        * (general) These changes collectively add route-map and
          prefix-list support to zebra and fix a bug in "show
          route-map" (with no argument).
        * command.h: added PROTOCOL_NODE type
        * log.c: (proto_name2num) new function, protocol name to
          number translation.
        * routemap.c: (vty_show_route_map) fixed "show route-map"
          without route-map name
        * routemap.h: added RMAP_ZEBRA type
        * zebra.h: added proto_name2num() prototype

2007-04-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.c: (quagga_timestamp) Optimize the subsecond timestamp generation.

2007-04-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * command.c: (config_write_host) Save "log timestamp precision"
          if not default value.
          (show_logging) Show configured timestamp precision.
          (config_log_timestamp_precision) Enable configuration of timestamp
          precision.
          (no_config_log_timestamp_precision) Restore default timestamp
          precision.
          (cmd_init) Install new timestamp precision commands.
        * log.h: (struct zlog) New timestamp_precision field.
          (quagga_timestamp) New function to generate a timestamp with the
          desired precision.
          (struct timestamp_control) Declare a structure for use in avoiding
          repeated duplicate calls to quagga_timestamp.
        * log.c: (quagga_timestamp) New function to generate a timestamp
          of the desired precision.
          (time_print) Call quagga_timestamp if the time hasn't already been
          calculated.
          (vzlog) Initialize a timestamp_control structure and pass it to
          time_print and vty_log.
          (zlog_backtrace) Fix 64-bit problem: cannot print size_t with %u.
        * vty.h: Must now include "log.h".
          (vty_log) Takes an additional struct timestamp_control argument.
        * vty.c: (vty_log_out) Use new struct timestamp_control and new
          quagga_timestamp function to print timestamps of the desired
          precision.
          (vty_time_print) Use new quagga_timestamp function.
          (vty_log) Accept new struct timestamp_control argument and pass it
          down to vty_log_out.

2007-04-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * smux.c: (smux_trap) Fix printf format to work with 64-bit size_t.

2007-04-07 Paul Jakma <paul.jakma@sun.com>

        * prefix.h: Add define to match IPv4 Link-Local addresses

2007-03-20 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.c: (mes_lookup) Make the function more robust: check for
          cases where the index does not match the key value at that position.
          If so, give a warning and fall back to a linear search.
          And improve the error message in cases where even that fails.

2006-12-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating
          whether a peer address has been configured.  Comment now shows
          the new interpretation of the destination addr: if ZEBRA_IFA_PEER
          is set, then it must contain the destination address, otherwise
          it may contain the broadcast address or be NULL.
          (CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete
          macros that were specific to IPv4 and not fully general.
          (CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag.
          (CONNECTED_PREFIX) New macro giving the prefix to insert into
          the RIB: if CONNECTED_PEER, then use the destination (peer) address,
          else use the address field.
          (CONNECTED_ID) New macro to come up with an identifying address
          for the struct connected.
        * if.c: (if_lookup_address, connected_lookup_address) Streamline
          logic with new CONNECTED_PREFIX macro.
        * prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros
          for better performance than the general prefix_copy function.
        * zclient.c: (zebra_interface_address_read) For non-null destination
          addresses, set prefixlen to equal the address prefixlen.  This
          is needed to get the new CONNECTED_PREFIX macro to work properly.

2006-10-14 Paul Jakma <paul.jakma@sun.com>

        * if.c: (general) Handle upgrades from SUNWzebra, which tried
          to track each logical interface as a seperate struct
          interface, to Quagga, which assigns only one struct interface
          per ifindex.
          (if_sunwzebra_get) Try decompose a logical interface name
          (fooX:Y) to the 'primary' name (fooX), for Solaris.
          (interface_cmd) Use if_sunwzebra_get on Solaris.

2006-09-26 Pierre-Yves Ritschard <pierre-yves@spootnik.org>

        * smux.c: (smux_open,smux_trap,smux_register) Fix various
          asn_build_* calls to pass the proper length in the final
          argument: use sizeof(<variable>) instead of sizeof(<type>),
          since there were several inconsistencies between the actual
          variable type and the size that was passed.  This should
          fix some problems on 64-bit architectures where sizeof(int)
          != sizeof(long).

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.

2006-07-25 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.

2006-07-10 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 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.).

2006-07-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * vty.c: (vty_log_out) Debug messages to terminal vty sessions
          should include timestamps.

2006-06-28 Paul Jakma <paul.jakma@sun.com>

        * memory.c: Fix typo in cpp conditional around malloc.h, from
          comment in bug #269.

2006-06-27 Paul Jakma <paul.jakma@sun.com>

        * route_types.awk: Remove setting the 'bare' numeric route type
          in redist strings.

2006-06-15 Paul Jakma <paul.jakma@sun.com>

        * command.c: (cmd_describe_command_real) Fix leak, CID #38.
        * memory.h: Experimental, have XFREE macro NULL out the freed
          pointer.
        * linklist.c: (list_delete) call list_delete_all_node, don't
          duplicate it.
        * if.c: (if_flag_dump) remove the whitespace indentation, callers
          should provide.

2006-05-28 Paul Jakma <paul.jakma@sun.com>

        * zebra.h: Include inttypes.h rather than stdint.h, best practice
          according to the autoconf manual.
          Add UINT*_MAX defines for older platforms lacking these (FBSD 4)
        * memory.c: malloc.h is deprecated in favour of stdlib.h, however
          we still need it on GNU Libc for mallinfo().
        * vty.c: (vty_log/vty_log_fixed) dont crash if called when vty
          hasn't been initiliased.
        * log.c: (general) Add support for Sun libc printstack().
          (hex_append) make the cpp conditional on general HAVE_STACK_TRACE
          define.
          (zlog_backtrace_sigsafe) Ditto. Add printstack() version of the
          the DUMP macro in this function.

2006-05-23 Paul Jakma <paul.jakma@sun.com>

        * route_types.txt: New file, table of ZEBRA_ROUTE definitions.
        * route_types.awk: New script, to parse previous and generate
          (for now) redistribute string defines.
        * Makefile.am: build route_types.h using previous two, ala
          memtypes.h, include the script and table file in EXTRA_DIST.
        * command.h: pull in route_types.h, add a REDIST_STR define.

2006-05-21 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.h: (struct connected) Document the meaning of the
          ZEBRA_IFC_REAL and ZEBRA_IFC_CONFIGURED flags.

2006-05-15 Paul Jakma <paul.jakma@sun.com>

        * log.c: (general) Generalise struct zebra_route_desc into
          struct zebra_desc_table and, similar to route_types, add a
          command_types table to describe Zserv protocol commands.
          (route_types[]) use a macro to use designated initialisers
          while avoiding tedious duplication.
          (zserv_command_string) lookup string from zebra_desc_table,
          similar to zebra_route_string
        * zebra.h: Add declaration for zserv_command_string, adjust the
          comments to reflect zebra_desc_table.

2006-05-13 Paul Jakma <paul.jakma@sun.com>

        * vty.c: (vty_describe_command) CID #39 fix was too hasty, just
          cause it /can/ leak doesn't mean it always will have, check
          first.

2006-05-12 Paul Jakma <paul.jakma@sun.com>

        * plist.c: (vty_prefix_list_uninstall) Fix potential NULL deref
          of prefix and typestr strings, Coverity CID #3.
        * command.c: (cmd_complete_command_real) Fix leak of cmd_vector
          in error case, Coverity CID #37.
          (cmd_describe_command_real) Fix return of freed pointer when
          no-match, CID #55.
        * vty.c: (vty_describe_command) fix leak of describe vector in
          error path, CID #39.

2006-03-30 Paul Jakma <paul.jakma@sun.com>

        * command.h: (DEFUN_CMD_FUNC_TEXT) Annotate arguments as
          potentially being unused.
        * workqueue.c: (work_queue_run) fix line length of comment

2006-03-27 Paul Jakma <paul.jakma@sun.com>

        * memtypes.awk: Fix gensub call, g should be a string..

2006-03-25 Paul Jakma <paul.jakma@sun.com>

        * workqueue.h: (struct work_queue) Remove status field and
          state flag, no longer used.

2006-03-19 Paul Jakma <paul.jakma@sun.com>

        * memtypes.c: Add MTYPE_BGP_SYNCHRONISE.

2006-03-16 Paul Jakma <paul.jakma@sun.com>

        * Makefile.am: Fix -version-info argument.

2006-03-15 Paul Jakma <paul.jakma@sun.com>

        * memory.c: (mtype_memstr) new helper function to 
          return human friendly string for a byte count.
          (mtype_stats_alloc) new function, for users to retrieve
          number of objects allocated.
          (show_memory_mallinfo) New function, show mallinfo statistics
          if available.
          (show_memory_all_cmd) Call show_memory_mallinfo, if mallinfo
          is available.
        * memory.h: Export mtype_memstr and mtype_stats_alloc.
          Provide a define for a reasonable buffer size for
          mtype_memstr.
          
2006-03-14 Paul Jakma <paul.jakma@sun.com>

        * privs.c: (zprivs_caps_init) Change user IDs before lowering
          privileges, while this seems to work on Linux, on Solaris
          it rightfully refuses due to PRIV_PROC_SETID having been
          dropped.
        * command.h: Add the struct host global exported from command.c

2006-03-06 Paul Jakma <paul.jakma@sun.com>

        * if.h: export show_address_cmd, for anyone who wishes to use
          it.

2006-02-21 Paul Jakma <paul.jakma@sun.com>

        * sockunion.c: (sockunion_{su2str,log}) Use XSTRDUP.
          Particularly with _su2str, as that string gets XFREEd,
          which can be annoying if run debug code in memory.c.

2006-02-02 Paul Jakma <paul.jakma@sun.com>

        * workqueue.h: (struct work_queue) Remove the delay field.
          It served no purpose and just introduced bad behaviour.
          Should be excised before its allowed to escape into 1.0.
          This removes need for the 'flood' and runs_since_clear
          fields.
        * workqueue.c: (general) excise delay factor between queue
          runs, hence the 'flood' crap too.. See above.

2006-01-19 Paul Jakma <paul.jakma@sun.com>

        * stream.c: (stream_getq_from) should use POSIX uint64_t
          not u_int64_t. Latter is neither a traditional BSD type, nor
          a POSIX type.

2006-01-17 Vincent Jardin <vincent.jardin@6wind.com>

        * md5.c: Don't forget to keep const.
        * regex.c: Cleanup code and remove warnings.

2006-01-17 Paul Jakma <paul.jakma@sun.com>

        * md5.{c,h}: (md5_loop) Is better off taking a void * and doing
          cast to byte wise type internally, avoids needs for casts 
          in users.
        * vty.c: (no_terminal_monitor_cmd) New ALIAS for 
          terminal_no_monitor, in the more normal negating format,
          to be kind to my fingers.
          (vty_init) install new ALIAS.
        * zclient.{c,h}: (zclient_create_header) export this, seems others
          could use it (in lieu of more complete zserv helpers).

2006-01-16 Paul Jakma <paul.jakma@sun.com>

        * zclient.h: Update the Zserv protocol header with a version
          field.  Define the old command field to be a 'marker', to
          allow old Zserv and updated Zserv to be differentiated.
          Future updates will bump the version field obviously. New
          command field is made wider.  Try to stop using the
          'zebra_size_t' typedef in the callbacks.
        * zclient.c: Update to read/write new format header.

2006-01-11 Paul Jakma <paul.jakma@sun.com>

        * if.h: (struct interface) expand flags to 8 bytes.
        * zclient.c: (zebra_interface_{add,state}_read) stream read of
          interface flags now need to use stream_getq.
          (zebra_interface_if_set_value) ditto

2006-01-10 Paul Jakma <paul.jakma@sun.com>

        * stream.c: (stream_new) Allocate stream data as seperate object.
          (stream_free) free the data.
          (stream_resize) new function, resize stream to new size.
          (stream_{get,put}q*) new functions to get/put quad word size
          types.
        * stream.h: (struct stream) make data seperate from the stream.
          Export new stream_resize and quad-word get/put functions.
          
2005-12-29  Greg Troxel  <gdt@fnord.ir.bbn.com>

        * vty.c (vty_hello): add cast to quiet lint (from David Young)

2005-11-26 Paul Jakma <paul.jakma@sun.com>

        * buffer.c: (struct buffer_data) change gcc zero array
          declaration to C99 incomplete array.
        * stream.h: (struct stream) same

2005-11-24 Paul Jakma <paul.jakma@sun.com>

        * privs.c: (zcaps2sys/solaris) remove unused variable.
          (zprivs_state_caps/solaris) Format string missing a
          specifier.
        * zebra.h: s/u_int/unsigned int/, u_int is a BSD type, defining
          __USE_BSD on Linux pulls in further things from netinet/ip.h
          which dont preprocess for some reason. There is no C99
          shorthand type directly equivalent to u_int afaict, so don't
          use it.

2005-11-14 Paul Jakma <paul.jakma@sun.com>

        * (general) pass struct work-queue to callback functions.
        * workqueue.h: (struct work_queue) move the state flag
          variables to end.
          Add an opaque pointer to spec, for user-data global to the
          queue.
          Pass reference to work_queue to all callbacks.
        * workqueue.c: (work_queue_item_remove) pass ref to workqueue
          to user callbacks.
          (work_queue_run) ditto.

2005-11-14 Paul Jakma <paul.jakma@sun.com>

        * (general) Add state to detect queue floods.  There's no sense
          trying to be sparing of CPU resources, if the queue is
          flooding and using ever more memory resources. we should just
          get on with clearing the queue.
          The sense of delay and hold were wrong way around, fix.
        * workqueue.h: (struct work_queue) Add status bitfield.  Add
          'flood' integer to workqueue spec.  Add runs_since_clear
          counter to workqueue.
        * workqueue.c: (work_queue_new) set defaults for delay, hold
          and flood.
          (work_queue_add) initial schedule should use delay, not hold.
          (show_work_queues) Print flood field, conserve whitespace.
          (work_queue_unplug) use delay, not hold.
          (work_queue_run) consecutive runs should be seperated by hold
          time, not delay.
          Keep track of number of consecutive runs, go into 'overdrive'
          if queue is being flooded, we can't avoid making heavy use of 
          resources, better to use CPU than ever more RAM.
        * zebra.h: [bug #231] include stdint, if its there.

2005-11-05 Paul Jakma <paul.jakma@sun.com>

        * routemap.c: (vty_show_route_map_entry) call action is
          seperate from exit action, latter should still be printed
          regardless of whether a call is specified.

2005-11-03 Paul Jakma <paul.jakma@sun.com>

        * zebra.h: BSD BYTE_ORDER define isn't available everywhere,
          define if needs be.
        * checksum.h: new file. checksum.c exports in_cksum, provide
          a header for it.
        * checksum.c: (in_cksum) callers shouldn't have to know it uses
          a u_short internally, change to void *.
        * Makefile.am: Add checksum.h
        * command.h: remove bogus trailling slash.
        * md5.c: (general) Update it for the twentieth century. ANSI
          declarations are widely supported now.. Don't include system
          headers, only include zebra.h. Use POSIX types (the
          alternative is to define u_int64_t in a portable way - rest
          of Quagga needs same cleanup).
          Make endian-conditional code be compiler conditional rather
          than preprocessor conditional, so that breakage gets noticed
          quicker.
        * md5.h: POSIX types. Get rid of the odd __P() non-ANSI capable
          compiler compatibility hack.
        * if.c: (connected_free) use MTYPE for connected label.
        * memtypes.c: Add MTYPE_CONNECTED_LABEL
        * memtypes.h: Update auto-built file.

2005-10-26 Paul Jakma <paul.jakma@sun.com>

        * (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.
        * command.c: Use MTYPE_HOST, MTYPE_STRVEC. Some other fixups,
          including fixing some likely leaks in config_write_file.
        * vty.c: memory macro usage fixes. 
          (vty_read_config) fix leak where relative config file is
          specified.

2005-10-20 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-10-20 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-10-18 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * memtypes.h: Add MTYPE_OSPF_VERTEX_PARENT (to match memtypes.c).

2005-10-18 Paul Jakma <paul.jakma@sun.com>

        * memtypes.c: (memory_list_ospf) Add MTYPE_OSPF_VERTEX_PARENT.

2005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-09-29 Alain Ritoux <alain.ritoux@6wind.com>

        * smux.[ch]: allow to retreive global OID (identified by <0
          namelen).

2005-09-29 Paul Jakma <paul.jakma@sun.com>

        * 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.
          
2005-09-29 Alain Ritoux <alain.ritoux@6wind.com>

        * filer.c: show protocol name in filter_show()
        * plist.c: show protocol name in vty_show_prefix_entry()
        * routemap.c: show protocol name in vty_show_route_map_entry()
        * vty.c: in vty_command(), show protocol name if command unknown
        
2005-09-28 Alain Ritoux <alain.ritoux@6wind.com>

        * md5-gnu.h: removed
        * md5.h: replaces md5-gnu.h
        * Makefile.am: use correct md5.h
        * md5.c: import from WIDE

2005-09-21 Paul Jakma <paul.jakma@sun.com>

        * memtypes.{c,h}: Add MTYPE_AS_SEG_DATA.
        
2005-09-19 Hasso Tepper <hasso at quagga.net>

        * str.[ch]: Add strndup() from glibc.

2005-09-05 Paul Jakma <paul.jakma@sun.com>

        * 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.
        
2005-08-22 Hugo Santos <hsantos@av.it.pt>

        * 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
        
2005-08-10  Greg Troxel  <gdt@fnord.ir.bbn.com>

        * getopt.h: Don't declare getopt (rather than getopt_long), since
        quagga doesn't need it.
        * getopt.c (getopt): Don't define getopt.

2005-07-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
        * 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.

2005-07-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * prefix.c: (ip_masklen) While loop should test that 'pnt' pointer is
          in range before dereferencing it.

2005-06-24 Pawel Worach <pawel.worach@gmail.com>

        * getopt.h: add further tests for full getopt declaration on
          various systems.

2005-06-18 Paul Jakma <paul.jakma@sun.com>

        * memtypes.h: update autobuilt file to match memtypes.c changes

2005-06-01 Paul Jakma <paul.jakma@sun.com>

        * memtypes.c: Add MTYPE_BGP_PROCESS_QUEUE and
          MTYPE_BGP_CLEAR_NODE_QUEUE

2005-05-24 Paul Jakma <paul@dishone.st>

        * memtypes.h: update this auto-built file. (maybe we should just
          remove it, is GNU awk a terrible dependency to have?)

2005-05-23 Paul Jakma <paul@dishone.st>

        * 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.
        * 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.
        * 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.

2005-05-19 Paul Jakma <paul@dishone.st>

        * 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.
        * sockunion.c: (sockunion_getsockname) use MTYPE_SOCKUNION, not TMP
          (sockunion_getpeername) ditto
        * memtypes.c: (memory_list_bgp) add MTYPE_BGP_PEER_HOST

2005-05-15 Paul Jakma <paul@dishone.st>

        * 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
        
2005-05-07 Yar Tikhiy <yar@comp.chem.msu.su>

        * sockopt.c: Add support for BSD style ifindex in ip_mreq.

2005-05-06 Paul Jakma <paul@dishone.st>

        * (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 Hasso Tepper <hasso at quagga.net>

        * sockunion.c: Fix warning message.

2005-05-03 Paul Jakma <paul@dishone.st>

        * 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
          
2005-04-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        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.

2005-04-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * workqueue.c (show_work_queues): Remove unused gettimeofday call.

2005-04-27 Paul Jakma <paul.jakma@sun.com>

        * 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 >.
        * memory.h: memtypes is built source, default includes points to
          top_builddir, so we should refer to lib/memtypes.h

2005-04-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-04-25 Paul Jakma <paul.jakma@sun.com>

        * workqueue.{c,h}: Helper API for setting up and running queues via
          background threads.
        * command.c: install the 'show workqueues' command
        * memtypes.c: Add work queue mtypes, and a rib-queue type for
          a zebra rib work queue.
        * memtypes.h: Updated to match memtypes.c
        * Makefile.am: Refer to source files via srcdir variable, fix
          out-of-tree build breakage.
          Add new workqueue files to build.
        * memory.c: Make the string field much wider
        * memtypes.c: Correct the prefix list str/entry strings
        * thread.c: Kill unused TIMER_NO_SORT bits

2005-04-22 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-04-22 Paul Jakma <paul.jakma@sun.com>

        * 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.
        
2005-04-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-04-16 Paul Jakma <paul@dishone.st>

        * 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.

2005-04-15 Paul Jakma <paul@dishone.st>

        * 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.
          memtypes.awk is gawk dependent, use the GAWK automake var.
        * memtypes.h: New file, auto-generated, checked in for convenience.

2005-04-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-04-09 Jeroen Simonetti <jeroens@office.netland.nl>

        * routemap.c: Show description in "show route-map" output.

2005-04-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sigevent.c: On GNU_LINUX, check whether __USE_GNU is already defined.

2005-04-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * vty.c: (vty_log_fixed) Use casts to (void *) to try to eliminate
          compiler warnings when assigning a (const char *) value to
          struct iovec iov_base.

2005-04-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: If GNU_LINUX is defined, then define _GNU_SOURCE.  This
          fixes a problem where we were not getting the declaration of strnlen
          in <string.h>.

2005-04-08 Hasso Tepper <hasso at quagga.net>

        * routemap.[ch]: Added "description ..." command.

2005-04-08 Hasso Tepper <hasso at quagga.net>

        * prefix.[hc]: Pass argument to the inet6_ntoa by value making it more
          inet_ntoa alike.

2005-04-07 Paul Jakma <paul.jakma@sun.com>

        * linklist.h: Add usage comments.         
          Rename getdata macro to listgetdata.
          Rename nextnode to listnextnode and fix its odd behaviour to be
          less dangerous.
          Make listgetdata macro assert node is not null, NULL list entries
          should be bug condition.
          ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use
          with for loop, Suggested by Jim Carlson of Sun.
          Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the
          "safety" of previous macro.
          LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to
          distinguish from the similarly named functions, and reflect their
          effect better.
          Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section 
          with the old defines which were modified above, 
          for backwards compatibility - guarded to prevent Quagga using it..
        * linklist.c: fix up for linklist.h changes.
        * *.c: fix up for new list loop macro, try audit other loop
          usage at same time, to some degree.

2004-04-05 Hasso Tepper <hasso at quagga.net>

        * lib/prefix.[hc]: inet6_ntoa utility function copied from
          ripngd/ripngd.c (inet6_ntop).

2004-04-05 Paul Jakma <paul@dishone.st>

        * vty.c: Improve logging of failures to open vty socket(s).
          See bugid #163.

2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.h: Fix comments to reflect that if_lookup_by_name and
          if_get_by_name now require the argument strings to be NUL-terminated.
        * if.c: (if_lookup_by_name) Compare using strcmp.
          (if_get_by_name) Pass strlen(ifname) as 2nd arg to if_create.

2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.c: (if_nametoindex) The man page is rather vague, but it seems
          like the argument to if_nametoindex has an implicit maximum length
          of IFNAMSIZ characters.

2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.h: (if_lookup_by_name_len, if_get_by_name_len) New functions.
        * if.c: (if_lookup_by_name_len, if_get_by_name_len) New functions.
          (if_get_by_name) Tighten up code.
          (interface) Use new function if_get_by_name_len.
        * zclient.c: (zebra_interface_add_read) Use new if_get_by_name_len
          function.
          (zebra_interface_state_read) Use new if_lookup_by_name_len function.

2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * str.c: Replace strlcpy and strlcat with actual working versions
          copied from rsync-2.6.2/lib/compat.c.

2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.h: Remove define for IFINDEX_INTERNBASE and add define
          IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo-
          interfaces should have ifindex set to 0.
          (if_new) Remove function.
          (if_delete_retain) New function to delete an interface without
          removing from iflist and freeing the structure.
          (ifname2ifindex) New function.
        * if.c: (if_new) Remove function (absorb into if_create).
          (if_create) Replace function if_new with call to calloc.
          Set ifp->ifindex to IFINDEX_INTERNAL.  Fix off-by-one error
          in assert to check length of interface name.  Add error message
          if interface with this name already exists.
          (if_delete_retain) New function to delete an interface without
          removing from iflist and freeing the structure.
          (if_delete) Implement with help of if_delete_retain.
          (ifindex2ifname) Reimplement using if_lookup_by_index.
          (ifname2ifindex) New function to complement ifindex2ifname.
          (interface) The interface command should check the name length
          and fail with a warning message if it is too long.
          (no_interface) Fix spelling in warning message.
          (if_nametoindex) Reimplement using if_lookup_by_name.
          (if_indextoname, ifaddr_ipv4_lookup) Reimplement using
          if_lookup_by_index.

2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: Should include str.h to pick up missing functions.
        * str.h: Declare strnlen if needed.
        * str.c: Do not include str.h since zebra.h now includes it.
          (strnlen) New function.

2005-03-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: Must check whether __attribute__ should be defined before
          including zassert.h.

2005-03-14 Paul Jakma <paul.jakma@sun.com>

        * command.c: (sort_node) use vector_max instead of referencing 
          (struct vector *)->max directly. Test that vector_max is > 0 
          before using it to calculate an index.
          Fixup vector loop to make main body conditional on vector slot
          not being empty.
          (cmd_cmdsize) Fixup vector loop to make main body conditional on
          vector slot not being empty.
          (cmd_filter_by_completion) ditto
          (cmd_filter_by_string) ditto 
          (is_cmd_ambiguous) ditto
          (cmd_describe_command_real) Change index integers to unsigned.
          Test that vector_max is > 0 before using it to calculate an index.
          Return immediately with CMD_ERR_NO_MATCH if vline has no 
          active slots.
          Fixup vector loop to make main body conditional on vector slot
          not being empty.
          (cmd_complete_command_real) ditto.
          (cmd_execute_command_strict) Fixup vector loop to be conditional
          on non-null slot.
          (various) Fix indentation and other whitespace.
          vector.h: Rename to (struct vector).max to slightly less confusing
          active, for the number of active slots, distinct from allocated
          or active-and-not-empty. Rename vector_max to vector_active 
          for same reason.

2005-03-09 Paul Jakma <paul.jakma@sun.com>

        * command.c: Undo commit of sign warning fix and hidden command
          in list_cmd. Sign warning is more subtle. list_cmd on its own
          will be committed after.
        * command.c: (config_list_cmd) Don't list hidden or deprecated
          commands, hiding these from tab completion is still to be done.

2005-03-08 Paul Jakma <paul.jakma@sun.com>

        * command.c: (banner_motd_file_cmd) use XSTRDUP/XFREE.
          (no_banner_motd_cmd) use XFREE.
          (cmd_describe_command_real) sign compile warning fix
          (cmd_complete_command_real) ditto.
          (config_list_cmd) Don't list hidden or deprecated commands,
          hiding these from tab completion is still to be done.
        * command.h: cmd attr enum should start at 1.
        * vty.c: (vty_hello) suggestions from Andrew, read by line and
          stub out trailling non-printable characters on each line thus
          allowing us to specify VTY_NEWLINE to vty_out.

2005-03-08 Jeroen Massar <jeroen@unfix.org>

        * vty.c: (vty_hello) display motd file, if set
        * command.h: add char *motdfile to struct host
        * command.c: (config_write_host) write out motdfile config
          (banner_motd_file_cmd) new command, allow motd to be read from
          file.
          (no_banner_motd_cmd) free motdfile string, if needs be.
          (cmd_init) init (struct host).motdfile. Add new motd file
          commands.

2005-03-07 Michael Sandee <voidptr@voidptr.sboost.org>

        * command.c: host.name might be NULL.
        * vty.c: Fix fd leak.

2005-02-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * stream.c: (stream_read_try) Log a warning message if a fatal
          I/O error occurs.
          (stream_fifo_new) Fix prototype.
        * stream.h: Fix prototype for stream_fifo_new (need void arg).

2005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * {vty.h,vty.c}: Remove vty_finish (duplicate of vty_reset).

2005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * buffer.h: Make the struct buffer and struct buffer_data structures
          private by moving them inside buffer.c.  Add comments for all
          functions.  Rename buffer_write as buffer_put (to be more consistent
          with the buffer_putc and buffer_putstr functions).  Declare a new
          buffer_write function that is used to write data to a file descriptor
          and/or add it to the buffer queue.  Remove unused function
          buffer_flush_vty_all.  Create a new enum typedef buffer_status_t
          to be used as the return code for all buffer_flush* functions
          and buffer_write.
        * buffer.c: The struct buffer and struct buffer_data declarations
          are now private to this file.  In conjunction with that, remove
          some unnecessary fields: struct buffer (alloc, unused_head,
          unused_tail, length), struct buffer_data (prev).
          (buffer_data_new) Removed: functionality incorporated into buffer_add.
          (buffer_data_free) Removed: use a macro BUFFER_DATA_FREE instead.
          (buffer_new) Use calloc instead of malloc + memset(zero). 
          Supply an appropriate default size if the specified size is 0.
          (buffer_free) Eliminate code duplication by calling buffer_reset to
          free the contents of the buffer (and remove unused code related
          to unused_head).
          (buffer_empty,buffer_putc,buffer_putstr) Aesthetic change (make more
          compact).
          (buffer_reset) Use macro BUFFER_DATA_FREE.  No need to set
          alloc and length to 0 (these fields have been removed).
          (buffer_add) Fix scope to be static.  Call XMALLOC directly instead
          of calling removed buffer_data_new function.  Simplify the logic
          (since it's now a singly-linked list instead of doubly-linked).
          (buffer_write) Renamed to buffer_put.  Change to void, since return
          code of 1 was meaningless.  No need to adjust length field, since
          it has been removed.
          (buffer_putw,buffer_flush,buffer_flush_vty_all,buffer_flush_vty)
          Remove unused functions.
          (buffer_flush_all) Rewrite using buffer_flush_available to eliminate
          a possible failure mode if IOV_MAX is less than the number of buffers
          on the queue.
          (buffer_flush_window) Incorporate logic from buffer_flush_vty.
          Log an error message if there is a writev error.
          (buffer_flush_available) Be more paranoid: check for case where
          buffer is already empty.  Use new ERRNO_IO_RETRY macro, and use
          new enum for return codes.  Simplify deletion logic (since it's
          now a singly-linked list).
          (buffer_write) New function for use with non-blocking I/O.
        * vty.h: Replace the struct vty sb_buffer field with a fixed-size
          (5-character) sb_buf field and an sb_len field, since using
          a struct buffer was inappropriate for this task.  Add some useful
          comments about telnet window size negotiation.
        * vty.c: Include <arpa/telnet.h> (no longer included by zebra.h).
          Remove VTY_OBUF_SIZE (instead use buffer_new default size).
          Make telnet_backward_char and telnet_space_char static const.
          (vty_out) Replace buffer_write with buffer_put.
          (vty_log_out) Check for I/O errors.  If fatal, close the vty session.
          Consolidate 3 separate writes into a single write call.
          (vty_will_echo,vty_command,vty_next_line,vty_previous_line,
          vty_end_config,vty_describe_fold,vty_clear_buf,vty_serv_sock_addrinfo,
          vty_serv_sock_family,vty_serv_un,vty_use_backup_config,exec_timeout,
          vty_config_write,vty_save_cwd) Fix scope to static.
          (vty_new) Let buffer_new use its default buffer size.
          (vty_write) Fix signature: 2nd arg should be const char *.
          Replaced buffer_write with buffer_put.
          (vty_telnet_option) Fix minor bug (window height or width greater than
          255 was broken).  Use sb_buf and sb_len instead of removed sb_buffer
          (which was being used improperly).
          (vty_read) On error, use ERRNO_IO_RETRY to decide whether it's fatal.
          If the error is fatal, call buffer_reset so vty_close does not attempt
          to flush the data.  Use new sb_buf and sb_len instead of sb_buffer
          to store the SB negotiation string.
          (vty_flush) When vty->lines is 0, call buffer_flush_available instead
          of buffer_flush_window.  Look at the return code from buffer_flush
          to detect I/O errors (and in that case, log an error message and
          close the vty).
          (vty_create) Fix scope to static.  Initialize sb_len to 0 instead
          of creating sb_buffer.
          (vty_accept) Set socket nonblocking.
          (vtysh_accept) Use new set_nonblocking function instead of calling
          fcntl directly.
          (vtysh_flush) New function called from vtysh_read (after command
          execution) and from vtysh_write.  This flushes the buffer
          and reacts appropriately to the return code (by closing the vty
          or scheduling further flushes).
          (vtysh_read) Check whether error is fatal using ERRNO_IO_RETRY.
          If not, just try again later.  Otherwise, call buffer_reset before
          calling vty_close (to avoid trying to flush the buffer in vty_close).
          Fix logic to allow case where a command does not arrive atomically
          in a single read call by checking for the terminating NUL char.
          (vtysh_write) Use new vtysh_flush helper function.
          (vty_close) No need to call buffer_empty, just call buffer_flush_all
          in any case (it will check whether the buffer is empty).
          Do not free sb_buffer (since it has been removed).
          (vty_log_fixed) Use writev instead of write.
        * zebra.h: Do not include <arpa/telnet.h>, since this is used only
          by lib/vty.c.

2005-02-21 Vincenzo Eramo <eramo at infocom.ing.uniroma1.it>

        * pqueue.[ch]: Introduce "update" function to meet ospf spf needs. It
          will allow to update node when:
          i) a node is inserted into the priority queue;
          ii) a node position is modified in the priority queue;
        * pqueue.h: Export trickle_down() function.

2005-02-19 Paul Jakma <paul.jakma@sun.com>

        * stream.c: (stream_new) fix dumb mistake.

2005-02-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * stream.c: (stream_read_try) Use new ERRNO_IO_RETRY macro.

2005-02-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * network.h: Define a new ERRNO_IO_RETRY macro to test whether an I/O
          operation should be retried.  This eliminates the need to duplicate
          the same logic testing for EAGAIN or EINTR in multiple places.

2005-02-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * stream.h: Declare new function stream_read_try suitable for use
          with non-blocking file descriptors.  Indicate that stream_read
          and stream_read_unblock are deprecated.
        * stream.c: (stream_read_try) New function for use with non-blocking
          I/O.
          (stream_recvmsg) Should return -1 if the stream is too small to
          contain the data.

2005-02-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * network.c: (set_nonblocking) Should check return code from
          fcntl(F_GETFL).

2005-02-15 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
        
        * network.h: Declare new function set_nonblocking.  Indicate that
          readn and writen are deprecated.
        * network.c: (set_nonblocking) New function to make a file descriptor
          non-blocking, since it seems silly to have fcntl calls sprinkled
          throughout the code.

2005-02-14 Paul Jakma <paul.jakma@sun.com>

        * stream.h: Unsigned long updated to size_t
        * stream.c: ditto
        * stream.h: Add stream_copy, stream_dup, stream_recvmsg.
          Add comment describing struct stream abstraction, and various
          other comments.
          Deprecate several unsafe/ambigious macros.
          Add STREAM_WRITEABLE and STREAM_READABLE.
          Add (stream_getl_from) for symmetry.
          Update stream_forward_{endp,getp} to use size_t offset.
          Make stream data a 0 length array, rather than a seperate malloc.
        * stream.c: Add consistency checks. Update to follow stream.h
          changes.
          (stream_new) Alloc stream+data in one go.
          (stream_copy) new function, copy a stream.
          (stream_dup) new function, dup a stream.
          (stream_recvmsg) new function, recvmsg data into a stream.
          (stream_empty) no need to check getp == 0.

2005-02-09 Paul Jakma <paul.jakma@sun.com>

        * stream.h: Remove putp. Update reference to putp with endp.
          Add stream_forward_endp, which daemons were doing manually.
          Rename stream_forward to stream_forward_getp.
          stream.c: Remove/update references to putp.
          introduce stream_forward_endp.

2005-02-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: Change macro definitions SET_FLAG and UNSET_FLAG
          to use compound assignment operators (aesthetic change).

2005-02-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.c: (zlog_signal,zlog_backtrace_sigsafe) Eliminate use of fileno()
          since it is not async-signal-safe.
          (_zlog_assert_failed) Rewrite crashlog logic more compactly.
          (zlog_set_file,zlog_reset_file,zlog_rotate) Update logfile_fd
          for use in signal handler.

2005-02-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.c: (syslog_sigsafe) Reduce scope of syslog_fd: it is accessed
          inside this function only.
          (open_crashlog) New function to open /var/tmp/quagga.<daemon>.crashlog
          with flags O_WRONLY|O_CREAT|O_EXCL to save some crash info.
          (zlog_signal,_zlog_assert_failed) Increase logging priority from
          LOG_ERR to LOG_CRIT.  If no file logging is configured, try to use
          open_crashlog to create a crash logfile.
          (zlog_backtrace_sigsafe) If a crashlog file descriptor is open,
          dump a backtrace to that file.

2005-02-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if.h: Declare if_flag_dump.

2005-01-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * daemon.c: (daemon) Replace perror with zlog_err.
        * vty.c: (vty_serv_un) Replace perror with zlog_err.

2005-01-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * buffer.h: Fix comment on buffer_getstr to reflect that it now
          uses XMALLOC.
        * buffer.c: (buffer_getstr) Use XMALLOC(MTYPE_TMP) instead of malloc.
        * filter.c: (access_list_remark,ipv6_access_list_remark) Use
          argv_concat instead of buffer_getstr.
        * if.c: (interface_desc) Use argv_concat instead of buffer_getstr.
        * plist.c: (ip_prefix_list_description,ipv6_prefix_list_description)
          Use argv_concat instead of buffer_getstr.

2005-01-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * lib/buffer.h: Document behavior of buffer_getstr function.
        * lib/buffer.c: (buffer_getstr) Fix bug: must handle case where
          the string extends beyond the head struct buffer_data.

2005-01-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * lib/command.h: Document behavior of argv_concat function.
        * lib/command.c: (argv_concat) Calculate total string length first so
          we can call malloc just once (instead of realloc'ing to add each
          string element).
          (do_echo,config_logmsg) Allow for possible NULL return value from
          argv_concat.

2005-01-23 Hasso Tepper <hasso at quagga.net>

        * lib/command.[ch]: Make node_parent() function nonstatic. vtyh.c will
          use it as well.

2005-01-18 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.h: Test for SA_SIGINFO to see whether zlog_signal takes final
          two args (siginfo and program_counter).
        * log.c: (hex_append) Include this function only if SA_SIGINFO or
          HAVE_GLIBC_BACKTRACE is defined.
          (zlog_signal) Final two args (siginfo and program_counter) now
          depend on whether SA_SIGINFO is defined on this platform.
        * sigevent.c: (program_counter) Do not include this function if
          SA_SIGINFO is not defined on this platform.
          (exit_handler,core_handler) Test for SA_SIGINFO to decide whether
          2nd & 3rd arguments are present and to decide how to invoke
          zlog_signal.
          (trap_default_signals) Test for SA_SIGINFO and invoke sigaction
          appropriately.

2005-01-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.h: Change prototype for zlog_backtrace_sigsafe to take additional
          program_counter argument.
        * log.c: (zlog_backtrace_sigsafe) Add additional program_counter
          argument.  If it is non-NULL, use backtrace_symbols_fd to resolve
          the address.
          (zlog_signal) Call zlog_backtrace_sigsafe with additional
          program_counter argument.

2005-01-17 Hasso Tepper <hasso at quagga.net>

        * command.[ch], vty.c: cmd_execute_command() function must not attempt
          to walk up in the node tree if called from vtysh. Different daemons
          might have commands with same syntax in different nodes (for example
          "router-id x.x.x.x" commands in zebra/ospfd/ospf6d daemons).

2005-01-14 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * command.c (print_version): Do not bother even to examine host.name,
          since it is always NULL when this function is called from main.

2005-01-14  Greg Troxel  <gdt@fnord.ir.bbn.com>

        * command.c (print_version): Don't print host.name if it is NULL.
        Fixes segfault on Solaris reported by Goetz von Escher <goetz@open.ch>
        
2005-01-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sigevent.c: (trap_default_signals) Use the SA_SIGINFO flag to
          pass additional siginfo_t and ucontext_t arguments to core_handler
          and exit_handler.
          (core_handler,exit_handler) Now invoked with 3 arguments (using
          SA_SIGINFO).  Pass additional info to zlog_signal.
          (program_counter) New function to find program counter in ucontext_t,
          needs to be enhanced to support more platforms (currently works only
          on Linux/x86).
        * log.h: Change the zlog_signal prototype to add new arguments
          siginfo_t * and program_counter.
        * log.c: (zlog_signal) Add new arguments siginfo and program_counter.
          Include si_addr and program counter (if non-NULL) in message.
          And remove #ifdef HAVE_GLIBC_BACKTRACE around hex_append, since
          that is now used to render the si_addr and PC pointers.

2005-01-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: If not C99 and no va_copy macro available, fall back to
          memcpy (solves a build problem on FreeBSD 4.x).

2005-01-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether
          config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined
          by the configure test program).
        * sockopt.c: (getsockopt_cmsg_data) Use ZCMSG_FIRSTHDR instead
          of CMSG_FIRSTHDR.

2005-01-02 Hasso Tepper <hasso at quagga.net>

        * command.c: Revert int -> unsigned int fixes in
        cmd_describe_command_real() and cmd_complete_command_real(). index can
        be actually negative and it caused crash with "do<TAB>" in vty.

2004-12-29  Greg Troxel  <gdt@poblano.ir.bbn.com>

        * sockopt.c (getsockopt_ipv4_ifindex): Document calling
        convention.  Beef up comments.  Handle the case where the cmsghdr
        has a zero controllen, or more specifically when the wanted option
        is not present.  This is needed for Solaris 8, and in general for
        any platform for which configure finds a method and it can fail.
        Mark some changes with XXX to be cleaned up post 0.98.  
        
2004-12-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sockopt.c: (setsockopt_ipv4_ifindex) Improve error message.
          When neither IP_PKTINFO nor IP_RECVIF is defined, make return value
          deterministic (-1).

2004-12-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * thread.c: (funcname_thread_add_timer_msec) Reduce overflow risk.

2004-12-21 Paul Jakma <paul.jakma@sun.com>

        * if.h: Add more 'non-generic' IFF_ flags.
        * if.c: IFF_NOXMIT/IFF_VIRTUAL interfaces are 'loopback like'
        * stream.c: Dont allocate streams with 0 sized data buffers

2004-12-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * command.c: (do_echo) Added new "echo" command, useful for
          watchdog pinging to make sure the daemon is responsive.

2004-12-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
        
        * pid_output.c: (pid_output_lock) Eliminate static function, and just
          use the #ifdef to decide which version of the function to include.
          This eliminates a compilation problem with gcc4.  And fix the
          non-fcntl version so that it actually compiles.  Exit with
          status 1 instead of -1 on error.

2004-12-15 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sigevent.c: (trap_default_signals) Ignore SIGPIPE instead of exiting.

2004-12-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
        
        * log.c: (zlog_signal,_zlog_assert_failed) Change logging level back to
          LOG_ERR instead of LOG_EMERG.

2004-12-09 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.c: (hex_append) No need to include this function if
          HAVE_GLIBC_BACKTRACE is not defined.

2004-12-08 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * prefix.c: (prefix_copy) Error message before abort should
          have severity LOG_ERR, not LOG_INFO.
        * memory.c: (mtype_log) Log level should be LOG_DEBUG, not LOG_INFO.

2004-12-07 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * {smux.c,zclient.c}: Change level of debug messages to LOG_DEBUG.

2004-12-07 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * command.c: (config_write_host) Note that "log trap" is deprecated
          when writing out the config.

2004-12-07 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.h: Replace struct zlog flags and maskpri fields with maxlvl
          array to support individual logging levels for each destination.
          Remove the 2nd argument to openzlog since the default logging config
          should be standardized inside the library.  Replaced the
          zlog_set_flag and zlog_reset_flag functions with zlog_set_level.
          And zlog_set_file now requires an additional log_level argument.
          Declare zlog_proto_names for use inside command.c in the
          "show logging" command.  Added defines useful for command
          construction.
        * log.c: (vzlog) Decide where to send the message based on the
          individual logging levels configured for each destination.
          Remove support for ZLOG_STDERR since it was never actually used.
          Support record-priority for terminal monitors.
          (zlog_signal,zlog_backtrace_sigsafe) Support destination-specific
          logging levels.  Remove stderr support (was never used).  Added
          support for terminal monitor logging.
          (_zlog_assert_failed) Increase message severity to LOG_EMERG.
          (openzlog) Remove 2nd argument since default config should be
          standardized in library.  By default, terminal monitoring
          is set to debug, and all other logging is disabled.
          (zlog_set_flag,zlog_reset_flag) Removed.
          (zlog_set_level) New function to replace zlog_set_flag and
          zlog_reset_flag.  Supports destination-specific logging levels.
          (zlog_set_file,zlog_reset_file) Support file-specific logging level.
          (zlog_rotate) Log an error message if fopen fails, and support
          new file-specific logging level.
        * command.h: Change DEFUN_CMD_FUNC_DECL and DEFUN_CMD_FUNC_TEXT so that
          command functions will be static instead of global.  Remove
          declarations for config_exit and config_help.  Define new macros
          DEFUNSH_ATTR, DEFUNSH_HIDDEN, and DEFUNSH_DEPRECATED so we can
          have deprecated commands in vtysh.  Similarly, for completeness,
          define macros ALIAS_SH, ALIAS_SH_HIDDEN, and ALIAS_SH_DEPRECATED.
          Also, fix bug in ALIAS_ATTR macro (didn't matter because it
          was never used).
        * command.c: Make many functions static instead of global.
          (facility_name,facility_match,level_match) New functions
          to support enhanced destination-specific logging levels.
          (config_write_host) Support new destination-specific logging levels.
          (config_logmsg) Added new "logmsg" command to help test logging
          system.
          (show_logging) Added "show logging" command to show the current
          configuration of the logging system.
          (config_log_stdout_level) Support explicit stdout logging level.
          (no_config_log_stdout) Now takes optional LEVEL arg.
          (config_log_monitor,config_log_monitor_level,no_config_log_monitor)
          New commands creating new "log monitor" commands to set terminal
          monitoring log level.
          (config_log_file_level) Support explicit file logging level.
          (config_log_syslog_level) Support explicit syslog logging level.
          (config_log_facility,no_config_log_facility) Implement new
          "log facility" command.
          (cmd_init) Add hooks for new commands: "show logging", "logmsg",
          "log stdout <level>", "log monitor", "log monitor <level>",
          "no log monitor", "log file <filename> <level>",
          "no log file <filename> <level>", "log syslog <level>",
          "log facility", and "no log facility".
        * vty.h: Added a "level" argument to vty_log so it can support
          "log record-priority".  Declare new function vty_log_fixed for
          use in signal handlers.
        * vty.c: (vty_log,vty_log_out) Added a "level" argument to support
          "log record-priority" for vty terminal monitors.
          (vty_down_level) Use config_exit_cmd.func instead of calling
          config_exit directly (since command functions will now be static
          instead of global).
          (vty_log_fixed) New function to send terminal monitor messages
          from inside a signal handler.

        * command.h: Remove fields log_stdout and log_syslog from struct host,
          since they are just trying to duplicate information in the
          zlog_default structure.  Note that this fixes a bug since those
          fields were not registering any logging that was established
          in the initial call to openzlog (this affects only the zebra and
          ospf6d daemons).  It is probably a bug to turn on any logging by
          default in the call to openzlog.
        * command.c: (config_write_host) Get logging info from zlog_default
          instead of now-removed fields host.log_stdout and host.log_syslog.
          (config_log_stdout,no_config_log_stdout) Do not set now-removed field
          host.log_stdout, since this info is recorded in zlog_default.
          (config_log_file) Use XSTRDUP (instead of strdup) to set host.logfile.
          (config_log_syslog,config_log_syslog_facility,no_config_log_syslog)
          Do not set now-removed field host.log_syslog, since this info is
          recorded in zlog_default.

2004-12-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * version.h.in: Remove declaration for pid_output_lock, this function
          is now static, not global.
        * pid_output.c: (pid_output_lock) This function should be static, not
          global.  And remove "old umask" error message, since it was really
          an unimportant debug message, not an error.
          (pid_output) Need to declare static function pid_output_lock.

2004-11-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * log.h: Remove several unused fields from struct zlog.  Add comments
          for other fields, and add one new field syslog_options that is
          used in the new syslog_sigsafe implementation.
        * log.c: (syslog_sigsafe) New function to send syslog messages in
          an async-signal safe way that can be used inside a signal handler.
          (syslog_connect) New function to connect to syslog daemon inside a
          signal handler.  This function supports only systems where /dev/log
          is a unix datagram socket (e.g. not Solaris).
          (zlog_signal) Call syslog_sigsafe if syslog logging is enabled.
          (zlog_backtrace_sigsafe) Call syslog_sigsafe if syslog logging is
          enabled.
          (openzlog) Save syslog_options for use in syslog_sigsafe.
          (num_append) Fix bug: handle 0 properly.
          (hex_append) New function to print a u_long in hex format.

2004-11-28 Hasso Tepper <hasso at quagga.net>

          (zlog_signal) Move backtrace code into separate function
          zlog_backtrace_safe.
          (_zlog_assert_failed) Call zlog_backtrace before aborting.

2004-11-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * Makefile.am: Need to add zassert.h to pkginclude_HEADERS.

2004-11-25 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zebra.h: If not C99 and there's no va_copy macro and there is
          a __va_copy macro, define va_copy as __va_copy.

2004-11-25 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * pid_output.c: (pid_output_lock) Fix 2 bugs: when locking, should
          set l_whence to SEEK_SET, not SEEK_END.  And after writing new
          pid to file, must ftruncate to eliminate any extraneous bytes left
          over from the last time a pid was written.

2004-11-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * zassert.h: New header file to declare a quagga-specific assert macro.

        * regex.c: Include "zassert.h" instead of <assert.h>.

2004-11-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sigevent.c: (signal_init) Set up some default signal handlers
          so that processes will issue an error message before terminating
          or dumping core.
          (trap_default_signals) New function to set up signal handlers
          for various signals that may kill the process.

        * log.c: (zlog_signal) New function to log information about
          a received signal before the process dies.  Try to log a 
          backtrace also.

2004-11-19 David Young <dyoung@pobox.com>

        * log.c: (safe_strerror) New function: safe wrapper for strerror.

2004-11-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * sockopt.c: (setsockopt_so_recvbuf) Stop error message from being
          printed every time.

2004-11-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * memory.h: Fix prototype for memory_init().
        * memory.c: Declare many functions and data structures static instead
          of global.  Fix prototype for memory_init().

2004-11-15  Greg Troxel  <gdt@fnord.ir.bbn.com>

        * sockopt.h: Avoid CMSG_ALIGN, and declare that sizes are without
        alignment (users should use CMSG_SPACE).

        * zebra.h: Rationalize CMSG_SPACE compatibility defines.  Warn if
        asumming 4-byte alignment, since this isn't safe.

2004-11-15 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * memory.c: (zerror) Use zlog_err instead of fprintf to stderr.
          Instead of exiting, log currenty memory usage and then abort.
          (log_memstats) New function to log memory statistics, called by
          zerror.
          (show_memory_all) Loop over new mlists array instead of calling
          show_memory_vty separately for each memory_list.

2004-11-08 Paul Jakma <paul@dishone.st>

        * buffer.c: Add missing include of log.h.
          (buffer_flush_available) written is compared against
          mostly against unsigned types, only for the writev do we need
          signed compare, so declare it as size_t and cast it to ssize_t
          just for the error compare when we've called writev.
        * buffer.h: Add comment that buffer data sizes really should be 
          size_t.

2004-11-07 Paul Jakma <paul@dishone.st>

2004-11-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * vty.h: Remove fields in struct vty that were related to VTY_CONTINUE
          capabilities (that were used only in bgpd/bgp_route.c and are now
          removed).  Also remove some other fields that were not being
          used at all.
        * vty.c: (vty_execute) Do not test for obsolete status values VTY_START
          and VTY_CONTINUE.

          (vty_flush) Remove code to support VTY_START and VTY_CONTINUE.
          (vty_close) Remove code to cancel vty->t_output thread, since that
          thread was never actually used.

2004-11-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * vty.c: Vtysh connections to daemons should use buffering.
          (vty_out) Remove exception for vty_shell_serv, just use buffer_write.
          (vty_new) Increase output buffer size to 4096 rounded up to a
          multiple of pagesize.
          (vtysh_read) After command has been executed and all output buffered,
          call buffer_flush_available and schedule further writes if the
          buffers are not yet empty.
          (vtysh_write) New function to flush output to vtysh when the socket
          is writeable.
          (vty_event) Added new VTYSH_WRITE event for flushing buffers to vtysh
          clients.  Also, should save read thread in vty->t_read so the
          thread can be cancelled in vty_close.
        * buffer.h: In struct buffer_data, remove unused "parent" field.
          Convert "unsigned char *data" to "unsigned char data[0]" to save
          a malloc.  Declare new function buffer_flush_available that works
          with non-blocking sockets.
        * buffer.c: (buffer_data_new) Use a single malloc now that data is
          a variable-size array at end of structure.
          (buffer_data_free) Just a single free now that data is part of the
          structure.
          (buffer_write) Simplify the logic to make behavior more transparent.
          (buffer_flush) Decrease b->length as data is written out.

        * keychain.c: Convert some more strtoul users to VTY_GET_INTEGER.
        * memory.h: Add MTYPE_THREAD_FUNCNAME and MTYPE_THREAD_STATS
        * thread.c: Update stats and funcname alloc/free to use previous
          specific memory type defines. Use XCALLOC and sizeof the type,
          not the pointer.
        * smux.c: fix int to size_t compile warnings

2004-10-29 Paul Jakma <paul@dishone.st>

        * vty.c: Move setting of sock to O_NONBLOCK from vty_serv_un
          to vtysh_accept, where sock is the actual fd we wanted to set to
          O_NONBLOCK, ie the /connected/ vtysh unix socket.

2004-10-23 Hasso Tepper <hasso at quagga.net>

        * zclient.c: Unbreak reading interface update message. Might fix
        blocker bugzilla #109.

        * sockopt.c: (getsockopt_ipv4_ifindex) no ifindex should be 0, not
          -1. 
          (setsockopt_pktinfo) unexported
        * sockopt.h: Cleanup SOCKOPT_CMSG defines a bit. Add a throwaway
          define for SOPT_SIZE_CMSG_IFINDEX_IPV4 for systems which have
          neither IP_RECVIF nor IP_PKTINFO (eg openbsd), thanks to Rivo
          Nurges for highlighting problem and fix.
          Fix elif that should be an else.
        * command.h: Cleanup the defines a bit, add helper defines and
          collapse all defines to use those. Add an attribute field to
          cmd_element to support, eg hidden or deprecated commands, add
          defun defines for such. All that's left to do is add logic
          to command.c to check these attributes... ;)
        * zebra.h: reserve ZEBRA_ROUTE_HSLS

2004-10-19 Hasso Tepper <hasso at quagga.net>

        * version.h.in: Define copyright string QUAGGA_COPYRIGHT.

        * Makefile.am: Remove useless version.c and print_version.c files.

2004-10-19 Andrew J. Schorr <aschorr@telemetry-investments.com>

        * zclient.c: (zebra_interface_address_read) If the destination address
          is encoded as all zeroes, load it as a NULL pointer.
        * if.h: Add comment describing struct connected destination field
          and indicating that it may be NULL.  Define macros
          CONNECTED_DEST_HOST and CONNECTED_POINTOPOINT_HOST to help
          with PtP logic (distinguish between host and subnet addressing).
        * if.c: (if_lookup_address) Fix PtP logic to handle subnet addressing
          properly,
          (connected_lookup_address) ditto.
          (connected_add_by_prefix) Handle case where destination is NULL,
        * prefix.[c|h]: New functions ipv4_network_addr and
          ipv4_broadcast_addr.

        * smux.c, smux.h: Remove all defaults to initialize smux connection to
          snmpd by default even if not configured to do so. "smux peer OID
          <password>" initializes now connection and "no smux peer" terminates
          it.

2004-10-13 Paul Jakma <paul@dishone.st>

        * (global) more const'ification.
        * sockunion.c: (sockunion_su2str) buffer should be sized
          SU_ADDRSTRLEN.
          (sockunion_log) do not return stack variables, strdup buf before
          return.
        * vty.h: Fix up the VTY_GET_INTEGER macros. Testing caller supplied
          values against ULONG_MAX is daft, when caller probably has passed
          a type that can not hold ULONG_MAX. use a temporary long instead.
          Add VTY_GET_LONG, make VTY_GET_INTEGER_RANGE use it, make
          VTY_GET_INTEGER a define for VTY_GET_INTEGER_RANGE.

2004-10-11 Hasso Tepper <hasso at quagga.net>

        * command.h: Sync DEFUNSH with other macros.
        * sockunion.c, sockunion.h: More const strings.

          than char **, to begin process of fixing compile warnings in lib/.
          Nearly all other changes in this commit follow from this change.
        * buffer.{c,h}: (buffer_write) pointer-arithmetic is gccism, take
          const void * and cast an automatic const char *p to it.
          (buffer_putstr) add const
        * command.c: (zencrypt) const qualifier
          (cmd_execute_command_real) ditto

          (if_rmap_get) ditto.
        * log.{c,h}: Update with const qualifier.
        * plist.{c,h}: ditto.
        * routemap.{c,h}: ditto.

          quagga_signal_timer did. dont block signals at all as sig->caught
