The implementation in zebra and the zclient protocol allow to communicate
addresses to clients which are not yet in the kernel.
This is usually not done and most clients seem to expect an address to be
configured in the kernel when they receive it. Therefore, it seems
reasonable to issue a warning when advertising an address to the clients
that is not yet in the kernel.

Add the rib_dest_t structure to hold per-prefix state in the routing
information base. This gives us an appropriate place to maintain the
queueing state of a route_node. Queuing state was previously being
stored on the first rib in the list of ribs hanging off the
route_node.
* zebra/rib.h
- Add new structure rib_dest_t.
- Remove the rn_status field from 'struct rib', it is no longer
required.
- Add macros (RNODE_FOREACH_RIB, RNODE_FOREACH_RIB_SAFE) for
walking all 'struct ribs' corresponding to a route_node. These
hide the fact that there is an intermediate rib_dest_t
structure.
- Add a few utility inlines to go between a rib_dest_t and
associated structures.
* zebra/zebra_rib.c
- rib_link()/rib_unlink()
Tweak for new behavior, where the 'info' pointer of a route_node
points to a rib_dest_t. The list of ribs for a prefix now hangs
off of the dest.
Change the way we ref count route_nodes. We now hold a single
ref count on a route_node if there is a corresponding
rib_dest_t.
- Maintain the queuing state of a route_node on the flags field of
the rib_dest_t.
- Add the rib_gc_dest() function, which deletes a rib_dest_t if it
is no longer required. A rib_dest_t can be deleted iff there are
no struct ribs hanging off of it.
- Call rib_gc_dest() any time we unlink a rib from the
rib_dest_t. Currently we only need to call it once, just before
we return from rib_process().
* zebra/{redistribute,zebra_rib,zebra_snmp,zebra_vty}.c
Use new macros to walk over route_node ribs.
* lib/memtypes.c
Add memory type for rib_dest_t.

redistribute is currently limited to "known" protocols. there is no
reason for this limitation, so, remove it.

Don't need big buffer 1024 to hold IPV4 (INET_ADDRSTRLEN)
or IPv6 (INET6_ADDRSTRLEN) message.

* lib/prefix.h: Add define to match IPv4 Link-Local addresses
* zebra/redistribute.c: (zebra_check_addr) Don't redistribute routes
to IPv4 link-local prefixes, fixes bug #351.
* zebra/redistribute.h: Export zebra_check_addr.
* zebra/router-id.c: (router_id_bad_address) re-use zebra_check_addr
rather than implementing similar logic.
|

* 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.

* (global): Fix up list loops to match changes in lib/linklist,
and some basic auditing of usage.
* configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES
* HACKING: Add notes about deprecating interfaces and commands.
* lib/linklist.h: Add usage comments.
Rename getdata macro to listgetdata.
Rename nextnode to listnextnode and fix its odd behaviour to be
less dangerous.
Make listgetdata macro assert node is not null, NULL list entries
should be bug condition.
ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use
with for loop, Suggested by Jim Carlson of Sun.
Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the
"safety" of previous macro.
LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to
distinguish from the similarly named functions, and reflect their
effect better.
Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section
with the old defines which were modified above,
for backwards compatibility - guarded to prevent Quagga using it..
* lib/linklist.c: fix up for linklist.h changes.
* ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single
scan of the area list, rather than scanning all areas first for
INTER_ROUTER and then again for INTER_NETWORK. According to
16.2, the scan should be area specific anyway, and further
ospf6d does not seem to implement 16.3 anyway.
|
|
* redistribute.c: (zebra_check_addr,is_default,
zebra_redistribute_default,zebra_redistribute) Fix scope to be static.
|
|
* *.c: Change level of debug messages to LOG_DEBUG.
|
|
|
|
|
|
* 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.
|
|
* 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.
2004-05-09 Sowmini Varadhan <sowmini.varadhan@sun.com>
* zserv.c: (zsend_ipv{4,6}_{add,delete}_multipath) collapsed
into single zsend_route_multipath function.
(zsend_interface_{up,down}) collapsed into zsend_interface_update.
(zsend_interface_address_{add,delete}) collapsed into
zsend_interface_address.
(zsend_interface_add) send mtu6.
(zsend_interface_delete) ditto.
(zebra_write) remove unused function.
(various) Apply static qualifier. Add comments.
* zserv.h: Definitions changed as per above.
* redistribute.c: Changes as per zserv.c.
|
|
* lib/vty.{c,h}: Remove vty layer depending on a 'master' global,
pass the thread master in explicitly to vty_init. Sort out some
header dependency problems with lib/command.h
* zebra/: Move globals to struct zebrad. Update vty_init().
* (.*)/\1_main.c: update call to vty_init().
