zebra/ChangeLog

2005-05-06 Paul Jakma <paul.jakma@sun.com>

	* zserv.h: Remove ZEBRA_PORT definition, its in lib/zebra.h now

2005-04-28 Paul Jakma <paul.jakma@sun.com>

	* rib.h: (struct rib) Add lock field for refcounting.
	* zserv.h: (struct zebra_t) Add a ribq workqueue to the zebra
	  'master' struct.
	* zserv.c: (zread_ipv4_add) XMALLOC then memset should be XCALLOC.
	* zebra_rib.c: Clean up refcounting of route_node, make struct rib
	  refcounted and convert rib_process to work-queue. In general,
	  rib's should be rib_addnode'd and delnode'd to route_nodes, and 
	  these symmetrical functions will manage the locking of referenced
	  route_node and freeing of struct rib - rather than having users
	  manage each seperately - with much scope for bugs..
	  (newrib_free) removed and replaced with rib_lock
	  (rib_lock) new function, check state of lock and increment.
	  (rib_unlock) new function, check lock state and decrement. Free
	  struct rib if refcount hits 0, freeing struct nexthop's, as 
	  newrib_free did.
	  (rib_addnode) Add RIB to route_node, locking both.
	  (rib_delnode) Delete RIB from route_node, unlocking each.
	  (rib_process) Converted to a work-queue work function.
	  Functional changes are minimal, just arguments, comments and 
	  whitespace.
	  (rib_queue_add_qnode) Helper function to setup a ribq item.
	  (rib_queue_add) Helper function, same arguments as old
	  rib_process, to replace in callers of rib_process.
	  (rib_queue_qnode_del) ribq deconstructor.
	  (rib_queue_init) Create the ribq.
	  (rib_init) call rib_queue_init.
	  (remainder) Sanitise refcounting of route_node's. Convert to 
	  rib_queue_add, rib_addnode and rib_delnode. Change XMALLOC/memset
	  to XCALLOC. Remove calls to nexthop_delete and nexthop_free.
	  
2005-04-10 Paul Jakma <paul@dishone.st>

	* if_ioctl_solaris.c: (if_lookup_linklocal) fix order of args
	  in ALL_LIST_ELEMENTS_RO macro.

2005-04-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* zserv.c (zebra_client_read): Fix bug: first read attempt should
	  read ZEBRA_HEADER_SIZE minus the number of bytes already read.
	  Improve efficiency by maintaining a calculation of the number
	  of bytes read instead of calling stream_get_endp multiple times.
	  If message length is too small, issue a warning message (not debug)
	  before closing the connection.  And also check that message length
	  is not too big.

2005-04-09 Hasso Tepper <hasso at quagga.net>

	* rt_netlink.c: One tiny missing comma caused pointless debug messages
	  about IPv6 nexthops.

2005-04-09 Hasso Tepper <hasso at quagga.net>

	* rt_netlink.c (netlink_parse_info): Fix warning. It's safe to cast
	  status to unsigned here, because we already checked that it isn't
	  negative or 0.
	* rt_netlink.c (netlink_interface_addr): Prefix length belongs to the
	  address, not to the interface.
	* rt_netlink.c (netlink_route_multipath): Fix debug. No useless info
	  is printed out now and IPv6 info is handeled.

2005-04-05 Paul Jakma <paul@dishone.st>

	* zserv.c: print more helpful errors when we fail to successfully
	  bind and listen on zserv socket. Closes bugzilla #163.

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

	* 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.

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

	* 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.

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

	* 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.

2005-03-31 Hasso Tepper <hasso at quagga.net>

	* rt_netlink.c (netlink_talk_filter): Show always warning message,
	  it's not for debug.
	* rt_netlink.c (netlink_talk): Don't assume we use netlink_cmd
	  although we do now actually.
	* rt_netlink.c (netlink_route, netlink_route_multipath): Always use
	  netlink_cmd to send messages to the kernel.

2005-03-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* irdp.h: Add prototype for irdp_sock_init, and fix protos for
	  other irdp_* functions.
	* irdp_interface.c: (irdp_if_start) If irdp_sock is negative,
	  call irdp_sock_init to create the IRDP socket.
	  (irdp_if_init) Rename to irdp_init().
	  (get_iflist_ifp) Remove function that is a duplicate of
	  if_lookup_by_index.
	  (*) Make many functions static.  And remove superfluous "\n" from
	  several zlog messages.
	* irdp_main.c: (irdp_init) Remove function that used to call
	  irdp_if_init() and irdp_sock_init(), since we will now create
	  the socket only upon first use.
	  (irdp_sock_init) Do not update global irdp_sock variable, just
	  return the fd and assume that the caller will do so.  If setsockopt
	  calls fail, close the socket before returning -1.
	  (*) Make many functions static.
	* irdp_packet.c: Initialize irdp_sock to -1.
	  (irdp_read_raw) Call standard library function if_lookup_by_index
	  instead of get_iflist_ifp.
	  (irdp_recvmsg) Should be static, not global.

2005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* rt_netlink.c: (netlink_link_change) If the status of an
	  operative interface changes (e.g. MTU changes), the client
	  daemons should be notified by calling zebra_interface_up_update.
	  Previously, the information was being updated in zebra's
	  interface structure, but the clients were not notified of
	  changes to an operative interface.

2005-03-25 Jean-Mickael Guerin <jean-mickael.guerin@6wind.com>
	* interface.c, interface.h, rtadv.c, rtadv.h: modifications to 
	  IPv6 Neighbor Discovery according to RFC3775, section 7:
	  o 1-bit Home Agent flag management in Router Advertisement (7.1).
	  o 1-bit Router Address flag management in Prefix Information 
	    Option (7.2).
	  o Advertisement Interval Option (7.3)
	  o Home Agent Information Option (7.4)
	  o Changes to Sending Router Advertisements more frequently (7.5)

2005-03-13 Hasso Tepper <hasso at quagga.net>

	* zebra/interaface.c: "show interface description" command
	  implemented.

2005-03-12 Paul Jakma <paul@dishone.st>

	* rt_netlink.c: (netlink_route_multipath) dont set equalise flag.
	  No stock Linux kernel has ever supported it, and even if it had
	  it's not generally a good idea.

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

	* if_proc.c, ipforward_proc.c, rtread_proc.c: Fix fd leaks.

2005-03-06 Hasso Tepper <hasso at quagga.net>

	* zserv.c: Must include network.h and buffer.h for non-blocking I/O.
	  Remove global message_queue and t_write (need separate buffering for
	  each client).
	  (zebra_server_dequeue,zebra_server_enqueue) Remove functions
	  related to old buggy buffering code.
	  (zserv_delayed_close) New thread callback function to delete a client.
	  (zserv_flush_data) New thread callback function to flush buffered
	  data to client.
	  (zebra_server_send_message) Rewritten to use buffer_write (so
	  buffering of writes and non-blocking I/O work properly).
	  (zsend_interface_add,zsend_interface_delete,zsend_interface_address,
	  zsend_interface_update) Return 0 instead of -1 if !client->ifinfo
	  (this is not really an error).  Return value from
	  zebra_server_send_message.
	  (zsend_route_multipath,zsend_ipv4_nexthop_lookup,
	  zsend_ipv4_import_lookup) Return value from zebra_server_send_message.
	  (zsend_ipv6_nexthop_lookup) Fix scope to static, and return value
	  from zebra_server_send_message.
	  (zsend_router_id_update) Must use zebra_server_send_message instead
	  of deprecated writen function.  Return 0 instead of -1 if this client
	  is not subscribed to router-id updates (since this is not really
	  an error).
	  (zread_interface_add) Change type to static int.  If
	  zsend_interface_add fails or zsend_interface_address fails, return -1
	  immediately (since the client has had an I/O error).
	  (zread_interface_delete,zread_ipv4_add,zread_ipv4_delete,
	  zread_ipv6_add,zread_ipv6_delete,zread_router_id_delete) Return 0
	  to indicate success.
	  (zread_ipv4_nexthop_lookup) Return value from
	  zsend_ipv4_nexthop_lookup.
	  (zread_ipv4_import_lookup) Return value from zsend_ipv4_import_lookup.
	  (zebra_read_ipv6) Remove unused function.
	  (zread_ipv6_nexthop_lookup) Return value from
	  zsend_ipv6_nexthop_lookup.
	  (zread_router_id_add) Return value from zsend_router_id_update.
	  (zebra_client_close) Call buffer_free(client->wb) and
	  thread_cancel(client->t_suicide).
	  (zebra_client_create) Allocate client->wb using buffer_new.
	  (zebra_client_read) Support non-blocking I/O by using stream_read_try.
	  Use ZEBRA_HEADER_SIZE instead of 3.
	  (zebra_accept) Fix bug: reset accept thread at top.  Make client
	  socket non-blocking using the set_nonblocking function.
	  (config_write_forwarding) Fix scope to static.
	  (zebra_init) Remove initialization code for old buggy write buffering.
	* zserv.h: Add 2 new fields to struct zserv: struct buffer *wb
	  (to enable buffered writes with non-blocking I/), and 
	  struct thread *t_suicide to support delayed close on I/O
	  errors.
	* router-id.h: Remove prototypes for zread_router_id_add and
	  zread_router_id_delete (their scope should be static to zserv.c).

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

	* redistribute.c: (zebra_check_addr,is_default,
	  zebra_redistribute_default,zebra_redistribute) Fix scope to be static.

	  (main) Add a startup announcement using zlog_notice.

2004-11-25 Hasso Tepper <hasso at quagga.net>

2004-10-05 Paul Jakma <paul@dishone.st>

	* irdp_packet.c: (parse_irdp_packet) style issues.
	  Use sockopt_iphdrincl_swab_systoh.
          Try unbork the code. Checksum the ICMP data and actually 
          compare it to received checksum. Check data length against
          claimed length in header.
	  Always use ntoh.. when accessing addresses, even when the
          comparison happens to be endian-safe.
	  (send_packet) minor style isues. Use
          sockopt_iphdrincl_swab_htosys.
	  (irdp_iph_hton/ntoh) IP header to/from network/host order.

2004-10-03 Gilad Arnold <gilad.arnold at terayon.com>

	* interface.c, interface.h: A new prefix tree of connected subnets is
	  associated with each interface structure in zebra, in which each
	  live (ie, non-synthetic) node holds a list of installed addresses
	  that belong to that prefix. Remove secondary address logic from cli.
	  See [quagga-dev 872] for detailed explanation.

	* Makefile.am: Compile new files.
	* main.c: Initialize router id.
	* redistribute.c: Add interface addresses into router id selection
	  lists as they (dis)appear.

          crash.

2004-08-31 Hasso Tepper <hasso at quagga.net>

	* main.c, rt_netlink.c: Added -s command line switch for tuning
	  netlink receive buffer size in Linux to avoid buffer overruns.

2004-08-26  Miles Nordin  <carton@Ivy.NET>

	* ipforward_sysctl.c (mib_ipv6): Use size_t for len, per

2004-08-11  Greg Troxel  <gdt@fnord.ir.bbn.com>

	* rtadv.c (rtadv_send_packet): Allocate space for control messages
	more carefully; it was wrong on NetBSD/sparc where CMSG alignment
	is to 8 bytes instead of 4, and overwriting the address.  Use the
	provided macros for determining lengths.

2004-07-23 Sowmini Varadhan <Sowmini.Varadhan@Sun.COM>

        * redistribute.h: include dependent header, zserv.h
        * zserv.h: include dependent header, rib.h

2004-06-30  Greg Troxel  <gdt@poblano.ir.bbn.com>

	* main.c: define thread_master variable so that linking with
	libzebra.so doesn't fail.  Arguably zclient.o should be in a
	separate library, but this is far less disruptive.

2004-06-12 Robert Olsson <Robert.Olsson at data.slu.se>

        * Added IRDP support.

2004-05-18 Hasso Tepper <hasso@estpak.ee>

	* kernel_socket.c (kernel_read): Use sockaddr_storage in buffer

	Solaris due to sockaddr_dl being large).  Thanks to Sowmini
	Varadhan for help with this change.

	* kernel_socket.c (ifm_read): Major cleanup.  Use Sowmini's code
	to find the sockaddr_dl in all cases, narrowing the Solaris ifdef
	to just the accomodation of broken kernels.  Check sockaddr_dl
	carefully up front, and later assume any non-NULL sdl pointer is
	valid.  Clean up types and variable declarations, and rename
	WRAPUP to SAROUNDUP to make the name fit the behavior.

2004-01-05  Greg Troxel  <gdt@fnord.ir.bbn.com>

	* kernel_socket.c (kernel_read): Add a sockaddr_dl to the ifmsg
	structure, because on Solaris sockaddr_dl is far larger than the

2004-01-05  Greg Troxel  <gdt@ahi.ir.bbn.com>

	* kernel_socket.c (kernel_read): Look up interfaces by index
	first, so that state changes which do not include a sockaddr_dl
	now work.  Add many sanity checks.  In
	particular, do not assume that a sockaddr_dl follows a message
	without checking the ifm_addrs flags, and do not trust the length
	in a sockaddr_dl.  Add/clarify many comments.

2003-12-03  Greg Troxel  <gdt@poblano.ir.bbn.com>

	* rtadv.c: reorder includes to avoid compiler warning (define

	  netlink_parse_info to deal with ACK messages.
