	* ripd.c: (show_ip_rip_status) Use new thread_timer_remain_second
	  function instead of rip_next_thread_timer to display the time until
	  next update properly.
	  (rip_next_thread_timer) Remove obsolete function. | 
|  | 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.
	* connected.c: (connected_up_ipv4, connected_down_ipv4,
	  connected_up_ipv6, connected_down_ipv6) Simplify logic using the
	  new CONNECTED_PREFIX macro.
	  (connected_add_ipv4) Set prefixlen in destination addresses (required
	  by the CONNECTED_PREFIX macro).  Use CONNECTED_PEER macro instead
	  of testing for IFF_POINTOPOINT.  Delete invalid warning message.
	  Warn about cases where the ZEBRA_IFA_PEER is set but no
	  destination address has been supplied (and turn off the flag).
	  (connected_add_ipv6) Add new flags argument so callers may set
	  the ZEBRA_IFA_PEER flag.  If peer/broadcast address satisfies
	  IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning.
	  Set prefixlen in destination address so CONNECTED_PREFIX will work.
	* connected.h: (connected_add_ipv6) Add new flags argument so
	  callers may set the ZEBRA_IFA_PEER flag.
	* interface.c: (connected_dump_vty) Use CONNECTED_PEER macro
	  to decide whether the destination address is a peer or broadcast
	  address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT).
	* if_ioctl.c: (if_getaddrs) Instead of setting a peer address
	  only when the IFF_POINTOPOINT is set, we now accept a peer
	  address whenever it is available and not the same as the local
	  address.  Otherwise (no peer address assigned), we check
	  for a broadcast address (regardless of the IFF_BROADCAST flag).
	  And must now pass a flags value of ZEBRA_IFA_PEER to
	  connected_add_ipv4 when a peer address is assigned.
	  The same new logic is used with the IPv6 code as well (and we
	  pass the new flags argument to connected_add_ipv6).
	  (if_get_addr) Do not bother to check IFF_POINTOPOINT: just
	  issue the SIOCGIFDSTADDR ioctl and see if we get back
	  a peer address not matching the local address (and set
	  the ZEBRA_IFA_PEER in that case).  If there's no peer address,
	  try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set.
	* if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl
	  without bothering to check the IFF_POINTOPOINT flag.  And if
	  no peer address was found, just try the SIOCGLIFBRDADDR ioctl
	  without checking the IFF_BROADCAST flag.  Call connected_add_ipv4
	  and connected_add_ipv6 with appropriate flags.
	* if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to
	  connected_add_ipv6.
	* kernel_socket.c: (ifam_read) Must pass new flags argument to
	  connected_add_ipv6.
	* rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2
	  to determine local and possible peer address (so there's no longer
	  a test for IFF_POINTOPOINT).  Set ZEBRA_IFA_PEER flag appropriately.
	  Pass new flags argument to connected_add_ipv6.
	  (netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast
	  to determine whether the connected destination address is a
	  broadcast address.
	* bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete)
	  Simplify logic by using new CONNECTED_PREFIX macro.
	* ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix,
	  ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX
	  macro.
	* ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX
	  macro, both options collapse into the same code.
	* ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new
	  CONNECTED_ID macro.
	  (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX
	  macro.
	* ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro
	  instead of testing the IFF_POINTOPOINT flag.
	* ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro
	  instead of testing with if_is_pointopoint.  And add commented-out
	  code to implement alternative (in my opinion) more elegant behavior
	  that has no special-case treatment for PtP addresses.
	  (ospf_network_run) Use new CONNECTED_ID macro to simplify logic.
	* rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID
	  macro to simplify logic.
	  (rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does
	  not give a useful result if prefixlen is 32 (we require a peer
	  address in such cases).
	* ripd.c: (rip_update_interface) Fix same bug as above. | 
|  | 2006-09-11 Paul Jakma <paul.jakma@sun.com>
	* rip_routemap.c: (route_set_metric) underflow check needs to
	  use signed, problem identified and diagnosed by Pavel
	  Nikiforov in bug #293. | 
|  | 2006-09-11 Paul Jakma <paul.jakma@sun.com>
	* ripd.c: (rip_read) remove gratuitous use of mid-function
	  declaration of vrecv, bug #278. | 
|  | 2006-06-29 Paul Jakma <paul.jakma@sun.com>
	* rip_zebra: (general) convert redistribute commands to use
	  the auto-generated defines. | 
|  | 2006-05-04 Paul Jakma <paul.jakma@sun.com>
	* (general) Fixes for bugs #261 and 262. Thanks to
	  Konstantin V. Gavrilenko <kos@arhont.com> for the problem
	  reports, testing of a series of proposed patches and comment
	  on the proposed changes in behaviour.
	* rip_interface.c: (ip_rip_authentication_mode_cmd) Parse all
	  of the command before making any changes to configured state.
	* ripd.c: (rip_read) RIP version control should be absolute and
          always apply, fixes bug #261 by allowing RIPv1 to be disabled.
	  Fix bug #262: If authentication is enabled, then
	  unauthenticated packets should not be accepted. We do however
	  make an exception for RIPv1 REQUEST packets, to which we will
	  reply as RIPv1 can now be disabled fully, to allow ripd to
	  still provide routing /information/ to simple devices. | 
|  | 2006-04-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
	* ripd.c: (rip_update_process) Try to fix the logic for sending
	  an updated on each connected network.  The new code will
	  attempt to send the update on each connected network, whereas
	  the previous code seemed to be attempting to avoid sending
	  more than one RIPv1 update on a given interface, but was coded
	  incorrectly.  The actual effect of the old code was to send
	  an update only on the first connected address in the cases
	  where the interface is not multicast, or RIPv2 is not being used. |

        * (general) various miscellaneous compiler warning fixes.
          Remove redundant break statements from switch clauses
          which return.
          return from main, not exit, cause it annoys SOS.
          Remove stray semi-colons which cause empty-statement
          warnings.
	* zebra/main.c: (sighup) remove private declaration of external
	  function. | 
|  | 2006-01-17 Paul Jakma <paul.jakma@sun.com>
	* ripd.c: (rip_auth_md5) remove pdigest, not needed.
	  Use a local buffer for the auth_str, where it can be properly
	  nul padded. Do so, hence fixing MD5 authentication.
	  Key looked up via key ring should be used in preference to
	  the RIPv1 simple password, not other way around.
	  No need to copy around digests, we can reference them
	  directly.
	  The auth_len received can't be trusted, some implementations
	  lie (e.g. older ripd).
	  (rip_auth_md5_ah_write) rename len local variable to doff
	  to be consistent with other functions.
	  (rip_auth_header_write) add the missing return.
	  (rip_auth_md5_set) use the proper constructs to access stream. | 
|  | * ripd.c: (rip_response_process) Instead of calling
	  rip_interface.c:if_valid_neighbor(), call the equivalent
	  library function if_lookup_address().
	* rip_interface.c: (if_valid_neighbor) Remove function, since it is
	  essentially equivalent to the if_lookup_address() library function.
	* ripd.h: (if_valid_neighbor) Remove function declaration. | 
|  | * Makefile.am: Add rip_interface.h, or else it doesn't get
	  included in dists. | 
|  | * ripd.c: Update couple more functions to specify void
	  explicitely. | 
|  | * (general) static/extern functions and definitions.
	* rip_interface.h: new file, export the public functions from
	  rip_interface.c | 
|  | * ripd.c: rip_create_socket() for each packet, it does not bind to the
          proper interfaces because we forget to use the from address when
          it is specified. | 
|  | * rip_interface.c: Now the command "no ip rip split-horizon
          poisoned-reverse" just inhibates the poisoned-reverse effects
          but keep spli-horizon activ. | 
|  | * zebra.h: Declare new functions zebra_route_string() and
	  zebra_route_char().
	* log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New
	  functions to map zebra route numbers to strings.
	* zebra_vty.c: (route_type_str) Remove obsolete function: use new
	  library function zebra_route_string() instead.  Note that there
	  are a few differences: for IPv6 routes, we now get "ripng" and
	  "ospf6" instead of the old behavior ("rip" and "ospf").
	  (route_type_char) Remove obsolete function: ues new library function
	  zebra_route_char() instead.  Note that there is one difference:
	  the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route,
	  whereas the new one returns 'X'.
	  (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace
	  route_type_str() with zebra_route_string().
	  (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char()
	  with zebra_route_char().
	* bgp_vty.c: (bgp_config_write_redistribute) Use new library function
	  zebra_route_string instead of a local hard-coded table.
	* ospf6_asbr.c: Remove local hard-coded tables zroute_name and
	  zroute_abname. Change the ZROUTE_NAME macro to use new library
	  function zebra_route_string().  Remove the ZROUTE_ABNAME macro.
	  (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with
	  a call to zebra_route_char(), and be sure to fix the format string,
	  since we now have a char instead of a char *.
	* ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and
	  zebra_route_abname.  Note that the zebra_route_name[] table
	  contained mixed-case strings, whereas the zebra_route_string()
	  function returns lower-case strings.
	  (ospf6_zebra_read_ipv6): Change debug message to use new library
	  function zebra_route_string() instead of zebra_route_name[].
	  (show_zebra): Use new library function zebra_route_string() instead
	  of zebra_route_name[].
	* ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto.
	  (ospf_redist_string) New function implemented using new library
	  function zebra_route_string().  Note that there are a few differences
	  in the output that will result: the new function returns strings
	  that are lower-case, whereas the old table was mixed case.  Also,
	  the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the
	  new function returns "ospf6".
	* ospfd.h: Remove extern struct message ospf_redistributed_proto[],
	  and add extern const char *ospf_redist_string(u_int route_type)
	  instead.
	* ospf_asbr.c: (ospf_external_info_add) In two messages, use
	  ospf_redist_string instead of LOOKUP(ospf_redistributed_proto).
	* ospf_vty.c: Remove local hard-coded table distribute_str.
	  (config_write_ospf_redistribute,config_write_ospf_distribute): Use
	  new library function zebra_route_string() instead of distribute_str[].
	* ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset,
	  ospf_redistribute_default_set,ospf_redistribute_check)
	  In debug messages, use ospf_redist_string() instead of
	  LOOKUP(ospf_redistributed_proto).
	* rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded
	  table str[]. Replace str[] with calls to new library function
	  zebra_route_string().
	* ripd.c: Remove local hard-coded table route_info[].
	  (show_ip_rip) Replace uses of str[] with calls to new library
	  functions zebra_route_char and zebra_route_string.
	* ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded
	  table str[].  Replace str[i] with new library function
	  zebra_route_string(i).
	* ripngd.c: Remove local hard-coded table route_info[].
	  (show_ipv6_ripng) Use new library function zebra_route_char() instead
	  of table route_info[]. | 
|  | * lib/filer.c: show protocol name in filter_show()
    * lib/plist.c: show protocol name in vty_show_prefix_entry()
    * routemap.c: show protocol name in vty_show_route_map_entry()
    * lib/vty.c: in vty_command(), show protocol name if command unknown
    * zebra/zserv.c: Always provide distance fo route add
    * ripd/rip_snmp.c: rip2IfConfReceive() sends values in conformance
      with RFC. Also PeerDomain is now set to a STRING type.
    * ripd/ripd.h: rip_redistribute_add() API includes metric and distance
    * ripd/ripd.c: rip_redistribute_add() API i.e. stores metric and distance
      Now allows a RIP-route to overcome a redistributed route coming
      from a protocol with worse (higher) administrative distance
      Metrics from redistribution are shown in show ip rip
    * ripd/rip_zebra.c: adapt to the rip_redistribute_add() API, i.e.
      provide distance and metric
    * ripd/rip_interface.c: adapt to the rip_redistribute_add() API
    * ripd/rip_routemap.c: no RMAP_COMPILE_ERROR on (metric > 16) usage
      rather a CMD_WARNING, because set metric ius shared with other
      protocols using larger values (such as OSPF)
      The match metric action takes first external metric if present
      (from redistribution) then RIP metric. | 
|  | * lib/md5-gnu.h: removed
    * lib/md5.h: replaces md5-gnu.h
    * lib/Makefile.am: use correct md5.h
    * lib/md5.c: import from WIDE
    * ospfd/ospf_packet.c: use new md5 API
    * ripd/ripd.c: use new md5 API | 
|  | * ripd.c: (general) Fix previous commit, broke multicast bind and
	  hence setting of source port, which broke communication with
	  non-borken ripd. Fix removes more stuff from rip_interface.c
	  than it adds to ripd.c ;)
	  (rip_create_socket) the to argument really is a from argument,
	  rename it. Set the source port to RIP port unconditionally, it's
	  required.
	  (rip_send_packet) Set from address correctly for multicast.
	  (rip_output_process) trivial: num can be BSS specified, rather
	  than in body.
	* rip_interface.c: (rip_interface_multicast_set) strip out
	  redundant stuff related to bind, which rip_create_socket does.
	  Just make it set the multicast socket option, as per the
	  interface concerned, no more. | 
|  | * ripd.c: (rip_create_socket) Make it static.
	  Remove the getservbyname stuff, as RFC2453 3.9.2 says non-RIP
	  port messages should be discarded, quagga doesnt accept them,
	  no need to lookup port.
	  Take a 'to' argument, if socket should be bound to something else.
	  setsockopt_so_recvbuf might need privs, move it to the raised
	  privileges section.
	  dont forget to close the socket if bind fails.
	  (rip_send_packet) use strncpy, just in case (address is under
	  our control anyway, but still).
	  dont duplicate rip_create_socket - just use it.
	  (rip_create) rip_create_socket takes an argument now, modify. | 
|  | * ripd.c: (rip_create_socket) move it up so rip_send_packet
	  can use it too. | 
|  | * rip_interface.c: Fix authentication, no-auth impossible to specify
	  (rip_interface_new) default to RIP_NO_AUTH
	  (rip_interface_reset) ditto
	  (rip_interface_config_write) write out config for simple | 
|  | * ripd.c: (rip_output_process) fix error which crept in my
	  previous rip auth untanglement commit - it had become impossible
	  to not have authentication (even for v1). |

	Fixes bugzilla #185. [backport candidate] |

	  rip_passive_interface_apply (was already calling it in
	  rip_interface_up).
	[backport candidate] | 
|  | 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. | 
|  | 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.

	  simple auth data psuedo-RTE. Make it do what its name suggests,
	  write out actual RTEs.

	  whether other platforms are affected).
	* zebra.h: Define ZCMSG_FIRSTHDR appropriately based on whether
	  config.h indicates HAVE_BROKEN_CMSG_FIRSTHDR (as determined

	  from LOG_WARNING to LOG_INFO.
	* vtysh.c: Make several functions static instead of global.
	  Added several commands to support 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. | 
|  | * bgp_main.c: (sigint) Use zlog_notice for termination message.
	  (main) Use zlog_notice for startup announcement.

	* 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.

|  | * ripd.c: Collapse redundant passing of various address structs,
          struct interface and struct connected as arguments to functions
          down to two key arguments, namely struct connected and, possibly,
          address of source/destination. Testing for RIPv1 would be useful.
          (rip_read) lookup struct connected for the received packet, pass
          it on.
        * rip_interface.c: With previous changes, we no longer have to tread
          carefully with struct connected, as it will always be there and
          valid. | 
|  | ripd might need some more testing though. | 
|  | initializes connection, and "no smux peer" command terminates it. Fixes
bugzilla #47 and #112. | 
|  |  | 
|  |  | 
|  |  | 
|  |  | 
|  | * ripngd/ripngd.c: move setsockopt_so_recvbuf to lib.
        * lib/sockopt.{c,h}: Add setsockopt_so_recvbuf, for ripd and ripngd.
        * ripd/ripd.c: set receive buffer to a decent size, some systems
          have low defaults. Problem noted and fix suggested by Stephan
          Schweizer in [zebra 20967]. | 
|  | * rip_interface.c: (rip_interface_multicast_set) get rid
          of extraneous if_pointopoint arg. ifp is accessible via connected.
          pass connected->ifp->ifindex to setsockopt_multicast_ipv4.

          if.c: ditto
        * network.c: (readn/writen) pointer arg should be type u_char.
        * plist.c: needs to include stream.h, not declare stream functions
          internally.
          (various) Add static qualifier to internal functions.
          (prefix_list_type_str) extraneous breaks in switch statement.
          (ip_prefix_list_description_cmd) buffer_putstr doesnt need cast
        * stream.h: depends on plist.h and export stream_put_prefix
        * vty.c: (vty_<telnet option build functions>) should use
          unsigned char, telnet options are 0 -> 255.
        * zclient.c: various u_char<->char type cleanups.
        * zebra.h: Having to define CMSG_* can apply to more than just
          BSDI_NRL.
        * ripd.c: (rip_distribute_update_all) distribute list hook
          function pointer prototype requires struct prefix_list * arg.
          (rip_distribute_update_all_wrapper) update to pass required arg,
          NULL. | 
|  | * ripd.h: Add define for the RIPv2 Authentication Data family
	  Move the auth type defines up to where other defines live.
	  Add RIP_AUTH_MD5_COMPAT_SIZE, for backwards compatible
	  md5->auth_len size. Add md5_auth_len field to struct
          rip_interface: (rip_interface_new) Init md5_auth_len to compatible
          size.
          (ip_rip_authentication_mode_cmd) Extended to handle setting

          compatible size.
          (rip_interface_config_write) Teach it about md5_auth_len.

          the setting in their config file, and hence allow for a future
          change of default for md5_auth_len to be less painful - every md5
          user will have this setting in their config file.
          ripd.c: (rip_packet_dump) Change nasty hard coded constants to
          symbolic defines. Change various tests of 'ntoh.(variable) ==
          constant' to test 'variable == ntoh.(constant)'. Clean up

          (rip_auth_simple_password) ditto.
          (rip_auth_md5) ditto, also add length argument and sanity check
          md5 data offset field. Sanity check md5 auth length, accept RFC
