lib/ChangeLog

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

	  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.

	  "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.

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

	* 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.

	* 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.

	  (num_append) Fix bug: handle 0 properly.
	  (hex_append) New function to print a u_long in hex format.

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.

	  (quagga_signal_handler,signal_set) Should be static.

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

	alignment (users should use CMSG_SPACE).

	* zebra.h: Rationalize CMSG_SPACE compatibility defines.  Warn if

	* 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>

	* version.h.in: add autoconf configure_input output var

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_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 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

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

	* vty.c: Move setting of sock to O_NONBLOCK from vty_serv_un

          -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>

	  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.

	  configuration from file. Fixes critical bugzilla #113.
	* smux.c, smux.h: Remove all defaults to initialize smux connection to

	  <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

          (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.

          Nearly all other changes in this commit follow from this change.
        * buffer.{c,h}: (buffer_write) pointer-arithmetic is gccism, take

	  is left intact under an ifdef, should some platform require it.
	  Check global caught flag before iterating through array.
