|  | * 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. | 
|  | * 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 | 
|  | * 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. | 
|  | * (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 | 
|  |  | 
|  | * 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 | 
|  | 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. | 
|  | * workqueue.c (show_work_queues): Remove unused gettimeofday call. | 
|  | * memory.h: memtypes is built source, default includes points to
	  top_builddir, so we should refer to lib/memtypes.h | 
|  | * 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. | 
|  |  | 
|  | * 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: Add new workqueue files to build. | 
|  | * thread.c: Kill unused TIMER_NO_SORT bits | 
|  | to HACKING (which I added..) | 
|  | * memory.c: Make the string field much wider
	* memtypes.c: Correct the prefix list str/entry strings | 
|  | * Makefile.am: Refer to source files via srcdir variable, fix
	  out-of-tree build breakage. | 
|  | * 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. | 
|  | * 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. | 
|  | * Makefile.am: memtypes.awk is gawk dependent, use the GAWK automake
	  var.
	* memtypes.h: New file, auto-generated, checked in for convenience. | 
|  | * 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. | 
|  |  | 
|  | * sigevent.c: On GNU_LINUX, check whether __USE_GNU is already defined. | 
|  | * 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. | 
|  | * 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>. | 
|  | Closes Bugzilla #167. | 
|  | inet_ntoa alike.
	* ripngd.[hc], ripng_interface.c, ripng_peer.c: inet6_ntoa() takes
	  argument now by value. | 
|  | * (global): Fix up list loops to match changes in lib/linklist,
	  and some basic auditing of usage.
	* configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES
	* HACKING: Add notes about deprecating interfaces and commands.
	* lib/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..
	* lib/linklist.c: fix up for linklist.h changes.
	* ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single
	  scan of the area list, rather than scanning all areas first for
	  INTER_ROUTER and then again for INTER_NETWORK. According to
	  16.2, the scan should be area specific anyway, and further
	  ospf6d does not seem to implement 16.3 anyway. | 
|  | ripngd/ripngd.c (inet6_ntop).
	* ripngd.[hc]: Remove inet6_ntop() and any usage of it. inet6_ntoa()
	  from lib is used now.
	* ripng_interface.c: inet6_ntop() -> inet6_ntoa().
	* ripng_peer.c: inet6_ntop() -> inet6_ntoa(). | 
|  | * lib/vty.c: Improve logging of failures to open vty socket(s).
	  See bugid #163.
	* zebra/zserv.c: print more helpful errors when we fail to successfully
	  bind and listen on zserv socket. Closes bugzilla #163. | 
|  | * if_ioctl.c: (interface_list_ioctl) Use if_get_by_name_len.
	* if_proc.c: (ifaddr_proc_ipv6) Increase size of ifname buffer to
	  avoid overflow.
	* kernel_socket.c: (ifan_read) Use if_get_by_name_len.
	* 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. | 
|  | * 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. | 
|  | * 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.
	* kernel_socket.c: (ifm_read) Use new if_lookup_by_name_len function
	  to save a memcpy.
	* if_ioctl_solaris.c: (interface_list_ioctl) Fix subtle bug with new
	  if_get_by_name_len function.
	* ospf_interface.c: (ospf_vl_new) Use strnlen to fix call to if_create. | 
|  | * str.c: Replace strlcpy and strlcat with actual working versions
	  copied from rsync-2.6.2/lib/compat.c. | 
|  | Fix problems when netlink interfaces are renamed (same ifindex used
	for a new interface).  Start cleaning up some problems with the way
	interface names are handled.
	* interface.c: (if_new_intern_ifindex) Remove obsolete function.
	  (if_delete_update) After distributing the interface deletion message,
	  set ifp->ifindex to IFINDEX_INTERNAL.
	  (if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is
	  IFINDEX_INTERNAL.
	  (zebra_interface) Check return code from interface_cmd.func.
	  Do not set internal ifindex values to if_new_intern_ifindex(),
	  since we now use IFINDEX_INTERNAL for all pseudo interfaces.
	* kernel_socket.c: (ifm_read) Fix code and comments to reflect that
	  all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL.
        * rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex.
	  Detects interface rename events by checking if that ifindex is already
	  being used.  If it is, delete the old interface before assigning
	  the ifindex to the new interface.
	  (netlink_interface, netlink_link_change) Call set_ifindex to update
	  the ifindex.
	* 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.
	* bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex
	  to IFINDEX_INTERNAL.
	* isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead
	  of if_delete, since it is generally not safe to remove interface
	  structures.  After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
	  (zebra_interface_if_lookup) Tighten up code.
	* ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function
	  was commented out.  But this is not safe: we should at least update
	  the ifindex when the interface is deleted.  So the new version
	  updates the interface status and sets ifp->ifindex to
	  IFINDEX_INTERNAL.
	  (ospf6_zebra_route_update) Use if_indextoname properly.
	* ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface
	  flags to help with debugging.
	* ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex
	  to IFINDEX_INTERNAL.
	  (zebra_interface_if_lookup) Make function static.  Tighten up code.
	* rip_interface.c: (rip_interface_delete) After deleting, set
	  ifp->ifindex to IFINDEX_INTERNAL.
	* ripng_interface.c: (ripng_interface_delete) After deleting, set
	  ifp->ifindex to IFINDEX_INTERNAL. | 
|  | * configure.ac: Add strnlen to AC_CHECK_FUNCS.
	* 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. | 
|  | must be after lib/ includes in some systems. Introduce SNMP_INCLUDES
	  for that. | 
|  |  | 
|  | * zebra.h: Must check whether __attribute__ should be defined before
	  including zassert.h.
	[backport candidate] | 
|  | * (global) update all c files to match the lib/vector.h rename of
	  (struct vector).active to max, and vector_max macro to
	  vector_active.
	* lib/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. | 
|  | * command.c: (various) Fix indentation and other whitespace. | 
|  | * 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. | 
|  | * command.c: (config_list_cmd) Don't list hidden or deprecated
	  commands, hiding these from tab completion is still to be done. | 
|  | * 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: (no_banner_motd_cmd) use XFREE.
	* vty.c: (vty_hello) fix the indentation and comment. |
