|  | * 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. | 
|  | * sockopt.c (getsockopt_ipv4_ifindex): Return 0 when passed a NULL
	  cmsghdr pointer.
I believe this will avoid ospfd crashing on Solaris 8, which seems to
define IP_RECVIF but not actually implement it. | 
|  | * sockopt.c: (setsockopt_ipv4_ifindex) Improve error message.
	  When neither IP_PKTINFO nor IP_RECVIF is defined, make return value
	  deterministic (-1). | 
|  | * thread.c: (funcname_thread_add_timer_msec) Reduce overflow risk. | 
|  | * stream.c: Dont allocate streams with 0 sized data buffers | 
|  | * if.h: Add more 'non-generic' IFF_ flags.
	* if.c: IFF_NOXMIT/IFF_VIRTUAL interfaces are 'loopback like' | 
|  | * command.c: (do_echo) Added new "echo" command, useful for
	  watchdog pinging to make sure the daemon is responsive. | 
|  | * 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. | 
|  | * sigevent.c: (trap_default_signals) Ignore SIGPIPE instead of exiting. | 
|  | * log.c: (zlog_signal,_zlog_assert_failed) Change logging level back to
	  LOG_ERR instead of LOG_EMERG. | 
|  | * log.c: (hex_append) No need to include this function if
	  HAVE_GLIBC_BACKTRACE is not defined. | 
|  | * 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. | 
|  | * {smux.c,zclient.c}: Change level of debug messages to LOG_DEBUG. | 
|  | * command.c: (config_write_host) Note that "log trap" is deprecated
	  when writing out the config. | 
|  | * bgp_main.c: (main) The 2nd argument to openzlog has been removed.
	* isis_main.c: (main) The 2nd argument to openzlog has been removed.
	* ospf6_main.c: (main) The 2nd argument to openzlog has been removed.
	  Note that stdout logging will no longer be enabled by default when
	  not running as a daemon.
	* ospf_main.c: (main) The 2nd argument to openzlog has been removed.
	* rip_main.c: (main) The 2nd argument to openzlog has been removed.
	* ripng_main.c: (main) The 2nd argument to openzlog has been removed.
	* main.c: (main) The 2nd argument to openzlog has been removed.
	  So stdout logging will no longer be enabled by default.
	* irdp_main.c: (irdp_finish) Reduce severity of shutdown message
	  from LOG_WARNING to LOG_INFO.
	* vtysh.c: Make several functions static instead of global.
	  Added several commands to support destination-specific logging levels.
	  (vtysh_completion) This function is unused, so comment it out.
	* basic.texi: Document new logging features.  Separate basic config
	  commands from basic VTY commands.
	* 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. | 
|  | * HACKING: Indicate that header files should be consulted for
	  documentation, particularly logging levels in lib/log.h.
	* log.h: Document appropriate use of syslog logging priorities
	  inside quagga. | 
|  | * 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. | 
|  | * bgp_main.c: (sigint) Use zlog_notice for termination message.
	  (main) Use zlog_notice for startup announcement.
	* isis_main.c: (sigint,sigterm) Use zlog_notice for termination message.
	  (terminate) This function should be static, not global.
	  (main) Use zlog_notice for startup announcement, and remove
	  ifdef ZEBRA_VERSION.
	* 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.
	* ospf6_main.c: (sigint,sigterm) Use zlog_notice for termination
	  message.
	  (main) Remove commented-out call to pid_output_lock (which should
	  never be called other than from inside pid_output).  And use
	  zlog_notice to print the startup message, which now includes
	  the vty port.
	* ospf_main.c: (sigint) Use zlog_notice for termination message.
	  (main) Issue a startup announcement using zlog_notice.
	* rip_main.c: (sigint) Use zlog_notice for termination message.
	  (main) Add a startup announcement using zlog_notice.
	* ripng_main.c: (sighup) Remove spurious terminating message.
	  (sigint) Use zlog_notice for termination message.
	  (main) Issue a startup announcement using zlog_notice.
	* main.c: (sigint) Use zlog_notice for termination message.
	  (main) Add a startup announcement using zlog_notice. | 
|  | * 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. | 
|  |  | 
|  | * log.c, log.h, memory.c: Change function name from zlog_backtrace_safe
	  to the more self-explanatory zlog_backtrace_sigsafe. | 
|  | * debug.[ch]: Remove unused files.
	* Makefile.am: Remove references to debug.c and debug.h
	* ospf_main.c: Remove #include "debug.h" (was not being used, and
	  lib/debug.h has now been deleted). | 
|  | * log.c: (zlog_backtrace) New function to log a backtrace.
	  (zlog_backtrace_safe) Log a backtrace in an async-signal-safe way.
	  Unfortunately, this function does not support syslog logging yet.
	  (zlog_signal) Move backtrace code into separate function
	  zlog_backtrace_safe.
	  (_zlog_assert_failed) Call zlog_backtrace before aborting.
	* log.h: Declare new functions zlog_backtrace and zlog_backtrace_safe.
	* memory.c: (zerror) Call zlog_backtrace before aborting. | 
|  | * Makefile.am: Need to add zassert.h to pkginclude_HEADERS. | 
|  | * 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. | 
|  | * 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. | 
|  | * zassert.h: New header file to declare a quagga-specific assert macro.
	* log.c: (_zlog_assert_failed) New function called when assert fails
	  to log the error and abort.
	* zebra.h: Include "zassert.h" instead of <assert.h>.
	* regex.c: Include "zassert.h" instead of <assert.h>.
	* dict.c: Include "zassert.h" instead of <assert.h>. | 
|  | * 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.
	  (exit_handler) Call zlog_signal, then _exit.
	  (core_handler) Call zlog_signal, then abort.
	* log.h: Declare new function zlog_signal.
	* log.c: (zlog_signal) New function to log information about
	  a received signal before the process dies.  Try to log a
	  backtrace also.
	  (quagga_signal_handler,signal_set) Should be static. | 
|  | * log.c: (vzlog) Take a single va_list argument and use va_copy
	  as necessary for multiple traversals.
	  (zlog) Pass only one va_list to vzlog.
	  (zlog_*,plog_*) Use a macro for boilerplate code; pass only one
	  va_list to vzlog.
	  (zlog_set_file) Remove unused 2nd argument (flags).
	  (zlog_save_cwd,zlog_get_cwd,zlog_free_cwd) Remove unused functions.
	* log.h: Remove ZLOG_*_INDEX defines (no longer used).
	  Remove unused 2nd argument from zlog_set_file prototype.
	  Fix prototype for zlog_rotate.
	* command.c: (config_log_file) Remove unused 2nd arg to zlog_set_file.
	* vty.c: (vty_out) Fix stdarg usage to perform multiple traversals
	  properly.

|  | * log.c: (safe_strerror) New function: safe wrapper for strerror. | 
|  | * sockopt.c: (setsockopt_so_recvbuf) Stop error message from being
	  printed every time. | 
|  | * memory.h: Fix prototype for memory_init().
	* memory.c: Declare many functions and data structures static instead
	  of global.  Fix prototype for memory_init(). | 
|  | in lib/zebra.h, ensure that RFC3542-required CMSG_SPACE and CMSG_LEN
  are defined.  Warn if alignment assumptions are made, since they are
  i386-centric.
  in lib/sockopt.h, declare that sockopt sizes are without
  CMSG_SPACE-required padding - just simple sizeof.
  in ospfd/ospf_packet.c, simply use CMSG_SPACE
This should remove all instances of CMSG_ALIGN from the source code.
This is a nonstandard, though rational, construct; quagga should use
only those defines in RFC3542. | 
|  | * 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. | 
|  |  | 
|  | * 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. | 
|  | * lib/version.h.in: add autoconf configure_input output var | 
|  | * 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_read) Remove calls to vty->output_func since that was part
	  of the VTY_CONTINUE infrastructure that has been removed.
	  (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.
	* bgp_route.c: Remove all code related to VTY_CONTINUE; this feature
	  is deprecated because the output did not represent a single point
	  in time.  All output needs to be generated inline and buffered
	  by the library code.
	  (route_vty_out,route_vty_out_tag,damp_route_vty_out,
	   flap_route_vty_out) Remove code to count number of lines of output,
	   since this was only useful for VTY_CONTINUE behavior.
	  (bgp_show_callback) Removed.
	  (bgp_show_table) Remove hooks for VTY_CONTINUE callback support.
	  As a result, there's a new output_arg argument to this function.
	  Make function static.
	  (bgp_show) Make function static and add a new output_arg argument.
	  Change all functions that call bgp_show or bgp_show_table to
	  pass the new output_arg argument (that used to be passed inside
	  vty->output_arg).
	* bgp_mplsvpn.c: Remove declarations of functions defined in
	  bgp_route.c; these declarations belong in bgp_route.h.
	* bgp_route.h: Declare 3 global functions used in both bgp_route.c
	  and in bgp_mplsvpn.c. | 
|  | * 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.
	  (buffer_flush_vty_all) Decrease b->length as buffers are freed.
	  (buffer_flush_vty) Decrease b->length as data is written out.
	  (buffer_flush_available) New function to flush non-blocking sockets. | 
|  | * sockopt.c: (setsockopt_pktinfo) remove, its unused. | 
|  | * thread.c: Use XCALLOC and sizeof the type, not the pointer. | 
|  | * smux.c: fix int to size_t compile warnings | 
|  | * 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 | 
|  | * keychain.c: Convert some more strtoul users to VTY_GET_INTEGER. | 
|  | * vty.c: As per Andrew's suggestions..
	  (vty_serv_un) remove flags.
	  (vtysh_accept) close socket if we cant set NONBLOCK. Add flags. | 
|  | * 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. | 
|  |  | 
|  | * zebra.h: reserve ZEBRA_ROUTE_HSLS | 
|  |  | 
|  | * sockopt.h: Fix elif that should be an else. |
