* configure.ac: Define HAVE_BSD_LINK_DETECT if <net/if_media.h> is
present.
* lib/zebra.h: If HAVE_BSD_LINK_DETECT is defined,

* zebra_routemap.c: (route_set_src_compile) Use '#ifdef HAVE_IPV6'
as needed.
* zebra_vty.c: (vty_show_ip_route_detail, vty_show_ip_route) Use

* kernel_socket.c: (ifam_read_mesg) Grab RTA_DST and RTA_GATEWAY
addresses from the message (if present, which seems unlikely on
current BSD platforms), and show them in the debug messages.
Also, add ifam_flags to the debug messages.
(ifam_read) If the interface is point-to-point, then the RTA_BRD
address should be treated as a peer address.

* interface.c: (if_delete_update) Address removal triggered
by kernel shouldn't remove configured IPv4 address from connected
list.
|
|
2007-04-08 Paul Jakma <paul.jakma@sun.com>
* {ioctl,kernel}_null.c: Install of IP address should
reflect back to zebra via kernel_address_add..., makes
testzebra more useful.

2007-03-06 Paul Jakma <paul.jakma@sun.com>
* kernel_socket.c: (ifam_read) Do not update interface metric on
receipt of NEW/DEL ADDR messages, bogus as: a) some systems
dont include iface metric for address events b) we didn't
update clients either. Initial diagnosis by Eugene Grosbein.
|

2007-02-26 Robert Olsson <Robert.Olsson@data.slu.se>
* irdp_main.c: (irdp_send_thread) Skip non-AF_INET addresses,
i.e. do not try interpret IPv6 addresses as IPv4 addresses
to broadcast in IRDP announcements..
|
|
2006-12-13 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* if_ioctl_solaris.c: (if_get_addr) For IPv6, stop assuming
that all IFF_POINTOPOINT have prefixlen of IPV6_MAX_BITLEN.
Instead, always try the SIOCGLIFSUBNET ioctl; if that fails,
then we fall back to IPV6_MAX_BITLEN for PtP interfaces.

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.

2006-12-08 Piotr Chytla <pch@packetconsulting.pl>
* zebra_rib.c: (static_install_ipv{4,6}) Case where existing
RIB is updated must explicitely rib_addqueue the route_node,
to ensure the update actually takes effect.
|
|
* kernel_socket.c (rtm_type_str): ifdef RTM_OLD{ADD,DEL} to
compile on systems that no longer define them.
|
|
2006-08-06 Paul Jakma <paul.jakma@sun.com>
* rtadv.h: depends on interface.h, so should include it.
|
|
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).
|
|
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.
|
|
2006-08-04 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.
|

2006-07-27 Paul Jakma <paul.jakma@sun.com>
* 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 Paul Jakma <paul.jakma@sun.com>
* debug.{c,h}: Add 'debug zebra rib' and 'debug zebra rib queue'.
|
|
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.
* zebra_rib.c: Add a global for the workqueue hold time, useful
for testing.
|
|
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>
* (general) The key fixes are actually Andrew Schorr's.
* interface.c: (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.
|
|
2006-06-15 Paul Jakma <paul.jakma@sun.com>
* lib/if.c: (if_flag_dump) remove the whitespace indentation, callers
should provide.
* zebra/interface.c: (if_flag_dump_vty) redundant code, remove.
(if_dump_vty) use libzebra if_flag_dump.
