Change the datastructure for recursive routes. This brings the following
benefits:
By using struct nexthop also to store nexthops obtained by recursive
resolution, we can get rid of quite a bit of code duplication in the fib
management. (rt_netlink, rt_socket, ...)
With the new datastructure we can make use of all available paths when
recursive routes are resolved with multipath routes.

Since commit ba281d3d040, ospfd uses NEXTHOP_IPV4_IFINDEX
routes. The API between zebra and bgpd which is used to query
nexthops for recursive routes did not support this nexthop
type and therefore, ospf changes (or any other IGP changes
which use NEXTHOP_IPV4_IFINDEX) would never trigger any
recursive route update.

Quagga makes bad assumptions about sockaddr_dl (on NetBSD, but possibly
on other systems as well). Particularly, sizeof(struct sockaddr_dl)
returns a size that does not include the full sdl_data field, leading to
not enough data being copied. This breaks IPv6 RAs in particular, as
a broken mac address from sockaddr_dl will be included in the packets.

Actually implement the IPV4_IFINDEX nexthop type that has been drifting
around as a definition forever (without any warning about it being a

Change interface up/down notification messages to also include the
hardware address of the interface. The format of these messages is now
identical to the interface add message -- move the serialization code
to common functions.
* lib/zclient.c: Modify zebra_interface_if_set_value() to also parse
the hardware address. Invoke it from zebra_interface_add_read()
and and zebra_interface_state_read().
* zebra/zserv.c: Add zserv_encode_interface(). Invoke it from
zserv_interface_add(), zserv_interface_delete() and
zserv_interface_update().
|
|
* zebra/zebra_rib.c: Add code to clean up routes added by a client
(as identfied by 'rib type').
* zebra/zserv.[ch]: Maintain the type of the routes added by a
client on the 'zserv' structure -- assume that a given client uses
a single route type for now.
Clean up routes from a client when the client goes away (in
zebra_client_close()).

ZEBRA_HELLO message is used by routing daemons to inform zebra
what type of routes daemon will be announcing to zebra. Also
zebra uses route_type_oaths array to track which daemon announces
which protocol. Zebra mops up routes if daemon didn't for some
reason.
|
|
All daemons modified to support custom path to zserv
socket.
lib: generalize a zclient connection
zclient_socket_connect added. zclient_socket and
zclient_socket_un were hidden under static expression.
"zclient_serv_path_set" modified.
|
|
This looks like a bug in original code from misunderstanding
of C rules of evaluation.
|
|
Move zserv socket creation code into zebra_zserv_socket_init() and
call it only after pidfile lock has been acquired exclusively. This
keeps subsequent zebra daemons from deleting the working socket of
an already running process (bug #403).
|
|
Quagga support linux policy routing (ip route ... table $X) with zebra.conf
table $X option. It works fine on ipv4. On ipv6 the parameter is ignored
(table 0 is used).
* zebra/...: Pass appropriate table arg to rib_{add,delete}_ipv6
|
|
The cmd_nodes used to configure vty, can mostly be static so
(basic data hiding 101).

* configure.ac: sys/conf.h depends on sys/param.h, at least on
FBSD 6.2.
(bug #363) Should check for in_pktinfo for IRDP
2006-05-27 Paul Jakma <paul.jakma@sun.com>
* configure.ac: General cleanup of header and type checks, introducing
an internal define, QUAGGA_INCLUDES, to build up a list of
stuff to include so as to avoid 'present but cant be compiled'
warnings.
Misc additional checks of things missing according to autoscan.
Add LIBM, for bgpd's use of libm, so as to avoid burdening
LIBS, and all the binaries, with libm linkage.
Remove the bad practice of using m4 changequote(), just
quote the []'s in the case statements properly.
This should fix bugs 162, 303 and 178.
* */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced
HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN,
* bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().

* lib/zclient.h: Update the Zserv protocol header with a version
field. Define the old command field to be a 'marker', to
allow old Zserv and updated Zserv to be differentiated.
Future updates will bump the version field obviously. New
command field is made wider. Try to stop using the
'zebra_size_t' typedef in the callbacks.
* lib/zclient.c: Update to read/write new format header.
* zebra/zserv.c: Ditto

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

8 bytes now, update to write out with stream_putq.

* 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.
|
|
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().
Forwardport from stable branch.
|
|
* 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) 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
|
|
* 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.
|
|
* 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.
|
|
* 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.
|
|
* (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.
|
|
* lib/vty.c: Improve logging of failures to open vty socket(s).
See bugid #163.
* zebra/zserv.c: print more helpful errors when we fail to successfully
bind and listen on zserv socket. Closes bugzilla #163.

(zserv_delayed_close) New thread callback function to delete a client.
(zserv_flush_data) New thread callback function to flush buffered
data to client.

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.

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).
|
|
* zserv.c: (zebra_read_ipv6) replace the char * arithmetic with
STREAM_READABLE.
|
|
* (global) Update code to match stream.h changes.
stream_get_putp effectively replaced with stream_get_endp.
stream_forward renamed to stream_forward_getp.
stream_forward_endp introduced to replace some previous
setting/manual twiddling of putp by daemons.
* lib/stream.h: Remove putp. Update reference to putp with endp.
Add stream_forward_endp, which daemons were doing manually.
Rename stream_forward to stream_forward_getp.
lib/stream.c: Remove/update references to putp.
introduce stream_forward_endp.

bugzilla #122, fix from wawa@yandex-team.ru (Vladimir Ivanov).
* kernel_socket.c: (routing_socket) ditto.

* zebra/zserv.c: (zebra_init) remove implicit ip forward enabling
* NEWS: warn about forwarding change
|
|
* zserv.c: (zsend_route_multipath) Set the nexthop_num

Conditionally set ZAPI_MESSAGE_METRIC flag - only for adds.
(zsend_ipv4_add) cruft, deleted.
(zsend_ipv4_delete) ditto.
