[zebra] trivial: rtadv.h depends on interface.h

[mirror_frr.git] / zebra / ChangeLog

2006-08-06 Paul Jakma <paul.jakma@sun.com>

        * interface.h: (ifstat_update_proc) declaration should match
          ifstat_update_sysctl really, which is to not return status, as
          such status is not used anywhere.
        * if_{proc,sysctl}.c: Make ifstat_update_* definitions and return values
          consistent with each other and their declarations, ie: 
          (void) (*) (void).
        * rtadv.h: depends on interface.h, so should include it.

2006-08-04 Paul Jakma <paul.jakma@sun.com>

        * misc_null.c: Add ifstat_update_sysctl, add another required
          header.

2006-08-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * misc_null.c: Must include header files to get older versions of gcc
          to process the #pragma statements properly.

2006-08-01 Paul Jakma <paul.jakma@sun.com>

        * irdp_main.c: (irdp_advertisement) free the stream here, when done,
          right under where it was allocated so it's blindingly obvious
          it's correct. This possibly fixes a very slow leak of streams in
          zebra.
        * irdp_packet.c: (send_packet) don't free the stream here as
          it's hard to tell if right, plus an error case seemed to
          returning before free anyway.

2006-07-27 Paul Jakma <paul.jakma@sun.com>

        * {ioctl,kernel}_null.c: Dummy/Null kernel method implementations,
          useful for testing zebra code that calls such methods.
        * {redistribute,misc}_null.c: Dummy/Null methods, as above. But
          for zclient, and for various misc functions.
        * test_main.c: Test harness for zebra, currently just to test the
          RIB.
        * Makefile.am: Build testzebra using above.
        * debug.{c,h}: Add 'debug zebra rib' and 'debug zebra rib queue'.
        * rib.h: (struct rib) Add a route_node rn_status flag field,
          this has to be copied every time head RIB of a route_node
          changes.
          Remove the rib lock field, not needed - see below. 
          Add a status field for RIB-private flags.
        * zebra_rib.c: Add a global for the workqueue hold time, useful
          for testing.
          (general) Fix for bug #268. Problem originally detailed by
          Simon Bryden in [quagga-dev 4001].
          Essentially, add/delete of a RIB must happen /before/ the
          queue. Best-path selection (ie rib_process) and reaping of
          freed RIBs can then be done after queueing. Only the route_node
          is queued - no important RIB state (i.e. whether a RIB is to be
          deleted) is queued.
          (struct zebra_queue_node_t) Disappears, no longer need to
          track multiple things on the queue, only the route_node.
          (rib_{lock,unlock}) removed, RIBs no longer need to be
          refcounted, no longer queued.
          (rib_queue_qnode_del) Removed, deleted RIBs no longer deleted
          via the queue.
          (rib_queue_add_qnode) deleted
          (rib_queue_add) Only the route_node is queued for best-path
          selection, we can check whether it is already queued or
          not and avoid queueing same node twice - struct rib * argument
          is not needed.
          (rib_link/unlink) (un)link RIB from route_node.
          (rib_{add,del}node) Front-end to updates of a RIB.
          (rib_process) Reap any deleted RIBs via rib_unlink.
          Unset the route_node 'QUEUED' flag.
          (General) Remove calls to rib_queue_add where add/del node was
          called - not needed, update calls where not.
          Ignore RIB_ENTRY_REMOVEd ribs in loops through route_nodes

2006-07-27 Rumen Svobodnikov <rumen@telecoms.bg>

        * connected.c: (connected_up_ipv4) interface connected routes always
          go to table main (or otherwise they cannot be used by linux as
          nexthops)
        * zserv.c: (zread_ipv4_add) send route to the correct routing table
        * zebra_rib.c (static_install_ipv4) set routing table

2006-07-02 Paul Jakma <paul.jakma@sun.com>

        * rt_netlink.c: (netlink_interface_addr) Fix CID #104, can not
          proceed if addr is NULL.
        * zebra_rib.c: (static_add_ipv6) Fix CID #18, double check
          required arguments are supplied for the given nexthop type.
        
2006-06-15 Paul Jakma <paul.jakma@sun.com>

        * interface.c: (if_flag_dump_vty) redundant code, remove.
          (if_dump_vty) use libzebra if_flag_dump.
          (ip_address_uninstall) Unset the configured flag.
        * connected.c: (connected_same) new helper, check whether
          two connected are same.
          (connected_implicit_withdraw) new helper, consolidation of
          existing code in connected_add_ipv{4,6}.
          Try filter out unneeded Zserv address delete/adds when
          address is exact same.
          Where old address is implicitely removed, be sure to preserve
          the IFC_CONFIGURED flag if set, fixes bug where configured
          addresses were being lost on FreeBSD (Andrew Schorr).   

2006-05-21 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * connected.c: (connected_withdraw) Do not delete the connected
          address if the ZEBRA_IFC_CONFIGURED flag is set.
          (connected_add_ipv4,connected_add_ipv6) Before calling
          connected_withdraw, unset the ZEBRA_IFC_CONFIGURED flag
          on the superseded connected structure.

2006-05-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * connected.c: (connected_add_ipv4,connected_add_ipv6) If the
          new struct connected matches an already existing one
          (that will consequently be removed by connected_withdraw),
          then be sure to preserve the ZEBRA_IFC_CONFIGURED flag.

2006-05-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * kernel_socket.c: (ifam_read_mesg) Improve debug message
          to show the IP address.

2006-05-15 Paul Jakma <paul.jakma@sun.com>

        * zserv.c: (general) Remove the private zebra_command_str
          in favour of newly added libzebra zserv_command_string.

2006-05-11 Paul Jakma <paul.jakma@sun.com>

        * interface.c: (if_delete_update) route_node_lookup may return
          NULL, should fix Coverity CID #31.

2006-02-09 Paul Jakma <paul.jakma@sun.com>

        * rib.h: (struct {rib,nexthop}) Rearrange fields to avoid
          needless padding. 
          (struct rib) Remove the indirect pointer, not used anywhere!

2006-02-02 Paul Jakma <paul.jakma@sun.com>

        * interface.c: (if_dump_vty) move flags to their line, neater.

2006-01-30 Paul Jakma <paul.jakma@sun.com>

        * zebra_rib.c: (rib_process) Fourth time lucky on this jinxed
          commit, last commit had a hole that could allow connected
          route selection to escape beyond the connected route logic. 
          This time I cross-checked with Gunnar first. ;)

2006-01-25 Gunnar Stigen <gunnar.stigen@axxessit.no>

        * zebra_rib.c: (rib_process) Application of Gunnar's earlier
          metric selection RIB change included incorrect tidy-ups made
          by commiter. Fix. (NB: any errors here are again due to paul).

2006-01-25 Paul Jakma <paul.jakma@sun.com>

        * (general) More solaris PF_ROUTE hacks. The IFF_UP mangling
          for solaris was incomplete on the PF_ROUTE side. fix it.
          This changeset generally uglifies things. For some future
          work I'd like to see the state changes seperated out from
          the details of the code. Differences between systems might
          then be slightly easier to implement without convoluted
          hacks.
          Changes should be specific to Solaris mostly, however
          also tested on FreeBSD 6.
        * if_ioctl_solaris.c: (interface_list_ioctl) ignore ~IFF_UP
          interfaces, we'll hear about them when/if interface goes up
          through NEWADDR.
          Update flags explicitely at end of it to kick mangling.
        * ioctl_solaris.c: (if_mangle_up) removed to interface.c, in
          kind.
          (lifreq_set_name) more convenient to take the string, than
          the ifp.
          (if_get_flags_direct) new convenience function, returns
          the actual flags. Used during bootstrap in if_ioctl_solaris.c
          to peek at flags of logical interfaces to see whether or
          not to ignore them.
          (if_get_flags) ENXIO means it's gone, poke out IFF_UP and
          kick flags update.
          (if_{un,}set_flags) flags argument should be 64bit.
        * ioctl.{c,h}: flags argument should be 64bit. 
        * interface.h: Add a 'primary_state' flag to struct zebra_if on
          SUNOS_5.
          Export if_flags_update.
        * interface.c: (if_flags_mangle) moved over in kind from
          ioctl_solaris.c. Nasty kludge to try get IFF_UP right, as
          much as is possible. Also keep track of the actual IFF_UP
          value for the primary interface, so we can know when the ifp
          must be deleted.
          (if_flags_update) Take a new interface flags value, apply it
          to the interface, and take whatever actions are required due
          to flag transitions.
          (if_refresh) flag state change logic is moved out to
          previous. Just call if_get_flags, which will end up using
          previous to effect the update of flags.
          (if_flag_dump_vty) IFF_IPV{4,6} aren't interesting, VIRTUAL
          and NOXMIT are though.
        * kernel_socket.c: (ifm_read) Down->Down transitions shouldn't
          create ifp, for non-IFANNOUNCE systems.
          Use if_flags_update to update flags.
          flag transition logic is now handled automatically through
          if_flags_update.
          (ifam_read) Better to call if_refresh *after* adding
          connected addresses, as connected count affects IFF_UP on
          IFF_UP-mangled systems.
          On Solaris, Up->Down due to DELADDR means we need to delete
          the ifp - the IFINFO might already have been and gone.
        * rt.h: include other dependent headers.

2006-01-19 Paul Jakma <paul.jakma@sun.com>

        * (general) various miscellaneous compiler warning fixes.
          Remove redundant break statements from switch clauses
          which return.
          Remove stray semi-colons which cause empty-statement
          warnings.
        * main.c: (sighup) remove private declaration of external
          function.
          (main) return from main, not exit, cause it annoys SOS.

2006-01-18 Gunnar Stigen <gunnar.stigen@axxessit.no>

        * zebra_rib.c: Take interface metric into account.

2006-01-17 Paul Jakma <paul.jakma@sun.com>

        * kernel_socket.c: (ifam_read) Read metric from RTM_NEWADDR.
          If interface is an alias, pass the alias as a label for
          connected_add_ipv{4,6}.
        * rt_netlink.c: (netlink_interface_addr) print out
          IFA_CACHEINFO info, if present, when debugging kernel
          messages.

2006-01-17 Gunnar Stigen <gunnar.stigen@axxessit.no>

        * connected.c: (connected_up_ipv{4,6}) Include interface metric on
          connected routes.
        * if_ioctl.c: (if_getaddrs) Be defensive about assuming
          that struct ifaddrs will have ifa_addr filled in.

2006-01-16 Paul Jakma <paul.jakma@sun.com>

        * zserv.c: Read/write updated Zserv header.

2006-01-11 Paul Jakma <paul.jakma@sun.com>

        * zserv.c: (zsend_interface_{add,delete,update}) if flags are
          8 bytes now, update to write out with stream_putq.

2005-12-29  Greg Troxel  <gdt@fnord.ir.bbn.com>

        * kernel_socket.c: remove dead code (from David Young).

        * rt_socket.c (kernel_rtm_ipv4): Use AF_INET rather than AF_UNSPEC
        for mask.  From David Young.

2005-11-26 Paul Jakma <paul.jakma@sun.com>

        * connected.{c,h}: (connected_add_ipv6) label should have
          const qualifier, fix declarations.

2005-11-24 Paul Jakma <paul.jakma@sun.com>

        * kernel_socket.h: New header for functions exported to sysctl
          methods.
        * kernel_socket.c: include previous.
          Remove static qualifier from couple of functions which are
          used by sysctl methods.
          Add a workaround for a bogus gcc warning to the RTA_ macros.
        * Makefile.am: Add kernel_socket.h to noinst_HEADERS
        * if_sysctl.c: include rt.h and kernel_socket.h and remove
          redundant prototypes.
        * rtread_sysctl.c: ditto.
          (route_read) fix mismatch of return values.
        * {rt,zserv,rib}.h: Include lib headers depended on.

2005-11-23 Paul Jakma <paul.jakma@sun.com>

        * (general) fix some small compile errors, and mark several
          functions as static.
        * kernel_socket.c: (ifan_read) should be static.
          fix missing brackets.
          (ifm_read,ifam_read,rtm_read_mesg,kernel_read) Make static
          (ifam_read_mesg) make static. fix incorrect variable name.
          (rtm_read) make static. Fix call to rib_delete_ipv4 which
          should be rib_delete_ipv6.
          (routing_socket,kernel_init) should be static. Void argument
          should be specified as such, not left incomplete.
        * rt_netlink.c: rt.h should be included, contains prototypes of  
          exported functions.
          (kernel_delete_ipv6_old) fix sign of index argument.   
        * rt_socket.c: Exact same as previous. Also, make various
          functions static.
        * rtread_getmsg.c: Include zserv.h, which prototypes
          route_read. Make static.
        * rtread_sysctl.c: zserv.h and rt.h should be included.
          fix definition of route_read.
   
2005-11-14 Paul Jakma <paul.jakma@sun.com>

        * zebra_rib.c: (rib_process) convert to new workqueue specs and
          shut up gcc, which complains about cast from void via
          function parameters, for some dumb reason. Do the cast
          inside the function instead.
          (rib_queue_qnode_del) ditto.
          (rib_queue_init) no need for the casts anymore.

2005-11-12 Alexander Gall <gall@switch.ch>

        * See [quagga-dev 1815]
        * kernel_socket.c: (rtm_write) Use SAROUNDUP when HAVE_SIN_LEN
          is not available.
        * rt_socket.c: (kernel_rtm_ipv6(_multipath)) set family to 
          AF_INET6 on ipv6 routes.

2005-11-12 Paul Jakma <paul.jakma@sun.com> 

        * kernel_socket.c: Add RTA_NAME_GET macro to extract name from
          sockaddr_dl. Add some more RTF_ flags.
        * (ifan_read) Add some debug messages.
        * (ifm_read) Add more debug messages. More robust cross-checks
          of index against name.
          Fall back to by-name lookup if the index lookup fails, future
          proofing more than anything else.
          (ifam_read_mesg) Read RTA_IFP. Add debug messages.
          (ifam_read) More debug. If there's an RTA_IFP and it isn't
          the name of the interface, save it as the label.
          (rtm_read_mesg) Read RTA_IFP.
          (rtm_read) allow name to be retrieved.
          (rtmsg_debug) expand on the debug message.

2005-11-11 Paul Jakma <paul.jakma@sun.com>

        * kernel_socket.c: (ifm_read) arithmetic on void pointer
          warning.
          (ifam_read) Fix error from connected-with-label merge,
          something crept in from the pending Solaris kernel_socket.c
          patch which shouldn't have.

2005-11-03 Paul Jakma <paul.jakma@sun.com>

        * connected.{c,h}: Include memory.h
          (connected_add_ipv4) Use MTYPE for ifc label.
          (connected_add_ipv6) Also should accept label. Store it in ifp.
          (connected_del_ipv4) Taking label as argument is pointless.
        * rt_netlink.c: (netlink_interface_addr) update label usage
          for connected_{add,delete} functions.
        * if_ioctl.c: (if_getaddrs) NULL label for connected_add_ipv6.
        * if_ioctl_solaris.c: (interface_list_ioctl) Pass LIFC_NOXMIT
          so we also find out about NOXMIT interfaces like VNI.
          Bit of hackery to turn interface names into the primary
          interface name, later with routing socket messages we only
          will about primary interfaces anyway, so we must normalise
          the name.
          (if_get_addr) take label as argument, so it can
          be passed to connected_add.
          If label is provided, then it is interface name to issue the
          ioctl for address information on, not the ifp name.
          (interface_list) List AF_UNSPEC too, just in case.
        * if_proc.c: (ifaddr_proc_ipv6) label for connected_add_ipv6.
        * interface.c: (if_addr_wakeup) Some very bogus code - sets
          IFF_RUNNING - add comment.
          (if_refresh)
          (ip_address_install) Use MTYPE for ifc label.
        * ioctl_solaris.c: (if_mangle_up) New function. Hackery to make
          IFF_UP reflect whether any addresses are left on the
          interface, as we get signalled for IFF_UP flags change on the 
          primary interface only. Logical interfaces dont generate
          IFINFO, but we do get an RTM_DELADDR.
          (if_get_flags) Call if_mangle_up before return.
        * kernel_socket.c: (ifam_read) Fixup calls to
          connected_{add,delete} to match above changes. Rename gate
          variable to brd, less confusing.
          Pass the interface name as a label, if it is not same name 
          as ifp->name.

2005-10-11 Paul Jakma <paul.jakma@sun.com>

        * connected.{c,h}: (connected_{add,delete}_ipv4) label should
          be const qualified.
        
2005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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().

2005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * rt_netlink.c: (netlink_request) Use memset to clear structure
          before calling sendto (eliminates a valgrind error message about
          uninitialized data).

2005-09-28 Alain Ritoux <alain.ritoux@6wind.com>

        * zserv.c: Always provied distance for route add

2005-09-28 Alain Ritoux <alain.ritoux@6wind.com>

        * connected.c: flag connected_up_ipv6() and connected_down_ipv6()
          usage with HAVE_IPV6

2005-09-24 Hasso Tepper <hasso at quagga.net>

        * rib.h: Add note about behaviour of rib_add_ipv[46]* functions -
          add is treated as implicit withdraw.

2005-09-21 David Young <dyoung@ojctech.com>

        * zebra_rib.c: Reduce the height of some staircases. Fix
          rib_delete_ipv6() to match routes in the RIB by their gateway as
          well as by destination.

2005-09-21 Paul Jakma <paul.jakma@sun.com>

        * zebra_rib.c: (static_uninstall_ipv{4,6}) Fix regression wrt
          removal of static routes with multiple-hops introduced with
          the workqueue conversion. We should free the relevant
          nexthop and then get rib_process to run, otherwise we just
          get same static route back again (with no way to unconfigure
          it, because its already deleted from configuration).
          
2005-09-12 Paul Jakma <paul.jakma@sun.com>

        * (general) RTM_CHANGE and implicit withdraw on RTM_NEWADDR
          support.
        * connected.c: (connected_withdraw) new function. withdraw a
          connected subnet address set from zebra, and pass information
          along to clients.
          (connected_announce) similar, but to announce a new connected
          subnet address set.
          (connected_check_ipv4) renamed to connected_check, as its
          AFI independent.
          (connected_add_ipv{4,6}) Remove the connected address announce
          stuff, use connected_announce instead.
          If connected_check indicates address is already present,
          treat it as an implicit withdraw of the existing address, ie
          remove the old address details and replace with the new
          details.
          (connected_delete_ipv{4,6}) Use connected_withdraw.
          (connected_check_ipv6) deleted in favour of connected_check.
        * connected.h: Rename connected_check_ipv4 to connected_check.
          delete connected_check_ipv6.
        * interface.c: Use connected_check rather than the AFI specific
          symbols.
        * kernel_socket.c: (rtm_read) RTM_CHANGE support. Create a 
          rib delete event for the existing route, before adding route
          again.
          (kernel_read) we can handle RTM_CHANGE now.

2005-08-27 Hasso Tepper <hasso at quagga.net>

        * zebra_rib.c, rib.h: Add distance and metric arguments to the
          rib_add_ipv6() function so that IPv6 routes in RIB can have correct
          metric. No IPv6 routing daemon uses distance yet though.
        * zserv.c, connected.c, kernel_socket.c, rt_netlink.c,
          rtread_proc.c,zserv.c: Pass metric and distance info to the
          rib_add_ipv6().

2005-07-29 Paul Jakma <paul.jakma@sun.com>

        * interface.c: (if_delete_update) should always be available, not
          just on RTM_IFANNOUNCE/NETLINK systems.
        * kernel_socket.c: (ifan_read) only call if_delete_update when
          interface departs, dont if_delete, because we wish to retain
          interface configuration state even when interfaces are removed.
          (ifm_read) If we dont have RTM_IFANNOUNCE, then transitioning
          to down state is only chance we have to clean up interface in case
          it is deleted (eg Solaris down -> unplumb -> plumb up).
        * redistribute.c: (zebra_interface_delete_update) should always be
          available, we /will/ call it now on all systems, via
          if_delete_update.
        * zserv.c: (zsend_interface_delete) ditto
          (zsend_interface_address) Update the call-flow diagramme, to
          reflect that if_delete_update /is/ now called on all systems,
          potentially.
        * zserv.h: (zsend_interface_delete) unconditionally exported, as
          above.
          
2005-06-28 Paul Jakma <paul.jakma@sun.com>

        * (global) Extern and static'ification, with related fixups
          of declarations, ensuring files include their own headers, etc.
        * if_ioctl.c: (interface_info_ioctl) fix obvious arg mis-order in
          list loop
        * kernel_socket.c: (RTA_{ADDR,ATTR}_GET) fix mistake, NULL check
          should be on DEST argument

2005-06-14 Paul Jakma <paul.jakma@sun.com>

        * kernel_socket.c: consolidate the IFAM{ADDR,MASK}GET and 
          RTM{ADDR,MASK}GET macros into generic rta_addrs macros,
          RTA_{ADDR,ATTR}_GET.
          (af_check) could use 'inline' attribute
          (ifam_read_mesg) remove IFAM{ADDR,MASK}GET macro, change to
          generic macro.
          (rtm_read_mesg) similar

2005-06-12 Hasso Tepper <hasso at quagga.net>

        * rt_netlink.c: Remove netlink-addr socket declaration, it's not used.
        * rt_netlink.c (netlink_parse_info): Fix debug messages - nlmsg_pid is
          unsigned and one zlog call had swapped arguments.
        * rt_netlink.c (netlink_route_multipath): Fix compile with disabled
          IPv6 support.

2005-05-31 Paul Jakma <paul.jakma@sun.com>

        * zserv.c: (zsend_route_multipath) Fix bug if route is sent
          with no NEXTHOP_FLAG_FIB nexthops. As ZAPI_MESSAGE_IFINDEX
          and ZAPI_MESSAGE_NEXTHOP are always set, clients would try
          read non-existent nexthop information and hit stream assert.
          Zserv is still broken for multi-nexthop messages, but it always was.

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>

        * interface.c: Fix CRC and frame errors statistics in Linux.

2005-02-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * 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.

2005-02-20 Hasso Tepper <hasso at quagga.net>

        * rt_netlink.c: Don't show messages "ignoring message type 0x001[89]"
          if we are not debugging.

2005-02-19 Paul Jakma <paul@dishone.st>

        * zserv.c: (zebra_read_ipv6) replace the char * arithmetic with

        * Not all Linux netlink systems have IFLA_WIRELESS

2005-01-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * ioctl.c: (if_ioctl,if_ioctl_ipv6,if_get_flags) Replace perror with
          zlog_err.
        * ioctl_solaris.c: (if_ioctl,if_ioctl_ipv6) Replace perror with
          zlog_err.

2005-01-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * if_ioctl_solaris.c: (interface_list_ioctl) Save errno before calling
          zserv_privs.change.
        * ioctl{,_solaris}.c: (if_ioctl,if_ioctl_ipv6) Save errno before calling
          zserv_privs.change.
        * ipforward_solaris.c: (solaris_nd) Save errno before calling
          zserv_privs.change.
        * irdp_main.c: (irdp_sock_init) Save errno before calling
          zserv_privs.change.

2005-01-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * rt_netlink.c: (netlink_socket,netlink_request,netlink_parse_info,
          netlink_talk) Save errno before calling zserv_privs.change.

2005-01-24 Martin Pot <mpot at martybugs.net>

        * zebra/rt_netlink.c: ignore wireless newlink netlink messages.

2005-01-18 Hasso Tepper <hasso at quagga.net>

        * interface.c: Better statistics output in "show interface" command in
          case of /proc being used.

2005-01-17 Hasso Tepper <hasso at quagga.net>

        * main.c: With --nl-bufsize argument is required.

2005-01-05 Paul Jakma <paul@dishone.st>

        * zserv.c: (zebra_accept) Comment out setting of socket to NONBLOCK
          for now, as we dont actually deal with with resending.... See
          bugzilla #122, fix from wawa@yandex-team.ru (Vladimir Ivanov).
        * kernel_socket.c: (routing_socket) ditto.

2005-01-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

        * rtadv.c: (rtadv_recv_packet,rtadv_send_packet) Use ZCMSG_FIRSTHDR

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.

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.
        * connected.c: Use if_subnet_add() and if_subnet_delete().

          there is non 127.x.x.x address in loopack interface, lowest of them
          is chosen. If there isn't, lowest from other interfaces addresses
          are chosen. "router-id x.x.x.x" vty command to manual override.
        * Makefile.am: Compile new files.
        * main.c: Initialize router id.

          to pointer.
        * if_ioctl{,_solaris}.c: lists typedef removal cleanup. 
          update some list loops to LIST_LOOP.

2004-09-23 Hasso Tepper <hasso at quagga.net>

        * *.[c|h]: list -> struct list *, listnode -> struct listnode *.

2004-09-22 Paul Jakma <paul.jakma@sun.com>

        * zserv.c: (zsend_route_multipath) fix nasty bad memset of struct
          in_addr to sizeof(struct in6_addr), causing odd and hard to debug
          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
          sysctl(3), rather than int.  (Needed on NetBSD/alpha to display
          forwarding status correctly.)

2004-08-23 Paul Jakma <paul@dishone.st>

        * zserv.c: (zebra_init) remove implicit ip forward enabling
        
2004-08-19 Paul Jakma <paul@dishone.st>

        * irdp_main.c: update to match sockopt renames.
        * irdp_packet.c: include sockopt.h and update to match sockopt
          renames.
                
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>

        * if_ioctl_solaris.c: HAVE_IPV6 ifdef fixups

        * irdp_main.c: Add privilege change.

2004-07-12  Hasso Tepper <hasso@estpak.ee>

        * irdp_interface.c: follow common style while naming vty command
          functions. Avoids confusion in extract.pl.

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>

        * rtadv.c: Removed "[no] ipv6 nd send-ra" command. Replaced "ipv6 nd
          prefix-advertisement" with "ipv6 nd prefix". Rewrite syntax of
          "ipv6 nd prefix" command to allow various combinations of parameters
          and flags. No defaults in configuration. Replaced on-link and
          autoconfig with off-link and no-autoconfig flags in command syntax.
          Cosmetic fixes in all commands. Documentation to reflect all changes.

2004-05-11 Paul Jakma <paul@dishone.st>

        * Makefile.am: support for IOCTL_METHOD, as per Sowmini's patch.

          add privs.h header.
        * ioctl_solaris.c: ditto
        * ioctl.h: Add if_ioctl_ipv6 prototype and AF_IOCTL for SOLARIS_IPV6
        * kernel_socket.c: Fix SAROUNDUP, compiler doesnt like do..while
          RHS in assignments :)
        * redistribute.c: (zebra_interface_delete_update) only used
          if RTM_IFANNOUNCE and NETLINK is available.
                 
2004-05-09 Paul Jakma <paul@dishone.st>

        * zserv.c: (zsend_route_multipath) Set the nexthop_num
          field correctly. Add NEXTHOP_TYPE_IPV6_IFNAME for v6.
          Conditionally set ZAPI_MESSAGE_METRIC flag - only for adds.
          (zsend_ipv4_add) cruft, deleted.
          (zsend_ipv4_delete) ditto.
          (zsend_ipv6_add) ditto.
          (zsend_ipv6_delete) ditto.
        * ioctl.c: (if_get_mtu) set mtu6 to mtu
        * mtu_kvm.c: (if_kvm_get_mtu) set mtu6 to mtu
        * rt_netlink.c: (netlink_interface) set mtu6 to mtu

        * if_ioctl_solaris.c: Add zprivs support.
        * ioctl_solaris.c: ditto.
                  
2004-05-09 Sowmini Varadhan <sowmini.varadhan@sun.com>

          (various) Apply static qualifier. Add comments.
        * zserv.h: Definitions changed as per above.

          with label.

2004-02-12  Hasso Tepper  <hasso@estpak.ee>

        * zserv.c: Added "ipv6 forwarding" command.

2004-01-08  Greg Troxel  <gdt@fnord.ir.bbn.com>

        * kernel_socket.c (kernel_read): Use sockaddr_storage in buffer
        for reading kernel messages to ensure enough space (necessary on
        Solaris due to sockaddr_dl being large).  Thanks to Sowmini
        Varadhan for help with this change.

2004-01-06  Greg Troxel  <gdt@t1.ir.bbn.com>

        * rtadv.c (rtadv_send_packet): Change perror to zlog_err.

2004-01-05  Greg Troxel  <gdt@fnord.ir.bbn.com>
        * 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
        base sockaddr structure.  (The code had previously been failing to
        read all the data.)
        
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
        structs before using them in prototypes)

2003-05-25 Jim Crumpler <Jim.Crumpler@edion.com>

  * zserv.c: Add "ip forwarding" command.

2003-05-16 Gilad Arnold <gilad.arnold@terayon.com>

        * zebra_rib.c (static_add_ipv4): Null0 static route is added.

2002-09-10  Jochen Friedrich <chris+zebra@scram.de>

        * rt_netlink.c: Add check for EAGAIN.
        * kernel_socket.c: Likewise

2002-06-12  Israel Keys <ikeys@oz.agile.tv>

        * rt_netlink.c: Setting the NLM_F_ACK flag on the netlink command
          message so that we get an ACK for successful netlink commands.
          Change the netlink socket to BLOCKING while we wait for a
          response; be it an ACK or an NLMSG_ERROR.  Change
          netlink_parse_info to deal with ACK messages.

2001-11-01  Jun-ichiro itojun Hagino <itojun@iijlab.net>

        * rtadv.c (rtadv_make_socket): setsockopt(IPV6_CHECKSUM) does not
        work for ICMPv6 socket.

2001-10-24  Kunihiro Ishiguro  <kunihiro@ipinfusion.com>

        * rib.c (rib_process): Select connected route any case.

2001-08-17  Kunihiro Ishiguro  <kunihiro@ipinfusion.com>

        * rib.c: Kernel route is treated as EGP routes in nexthop active
        check.

2001-08-15  Kunihiro Ishiguro  <kunihiro@ipinfusion.com>

        * zebra-0.92 released.

        (ipv6_nd_managed_config_flag): "ipv6 nd managed-config-flag" is
        added.
        (ipv6_nd_other_config_flag): "ipv6 nd other-config-flag" is added.
