Two extern declarations in ospf6_abr.h are based on struct ospf6_route,
which may not be available at the time ospf6_abr.h is included. This may
lead to warnings after including ospf6_abr.h just for the structures
defined in it.

|
|
|
* sockopt.c (setsockopt_ipv4_multicast_if): fix missed line in
the previous commit.
|
|
* ospf6_abr.c
* ospf6_abr_examin_summary(): only fill "buf" when it is used
|
|
* sockopt.[ch] (setsockopt_ipv4_multicast): ifindex is now mandatory (all
non-ancient OSes can use it anyway), and if_addr parameter (the address
of the interface) is now gone. (setsockopt_ipv4_multicast_if):
IP_MULTICAST_IF processing moved to this new function
* ospf_network.c (ospf_if_add_allspfrouters, ospf_if_drop_allspfrouters,
ospf_if_add_alldrouters, ospf_if_drop_alldrouters, ospf_if_ipmulticast),
rip_interface.c (ipv4_multicast_join, ipv4_multicast_leave,
rip_interface_new): adapt to the new interface
|
|
|
|
* bgp_nexthop.c (show_ip_bgp_scan_tables): access proper structure field
in AF_INET6 case, handle ifindex NH type properly
|
|
bgp_nexthop_onlink(): zlookup is not used here at all
bgp_nexthop_lookup_ipv6(): rely on the detection performed by "query"
function (this also changes the fallback value to 0), reorder if-block
bgp_nexthop_lookup(): idem
|
|
* bgp_nexthop.c: (show_ip_bgp_scan) transform into
show_ip_bgp_scan_tables(), which uses inet_ntop() and can dump
nexthops on request; (show_ip_bgp_scan_detail_cmd) new function
|
|
bgp_nexthop_lookup_ipv6(): declare variables where they are actually
used, drop no-op initialization (the field is already 0)
bgp_nexthop_lookup(): ditto
bgp_nexthop_check_ebgp(): rename to bgp_nexthop_onlink()
bgp_nexthop_cache_changed(): rename to bgp_nexthop_cache_different()
|
|
* bgpd: (bgp_damp_parameter_set) The BGP reuse_index is not initialized
properly. This would cause sporadic crash when disabling dampening. Use
XCALLOC correctly and the right size array is initialized and no memset is
needed.
|
|
The following patch was also neccessary to compile.
* command.c: (config_logmsg_cmd) use "%s" format spec
* if.c: (connected_log) ditto
|
|
* ospf_route.c: Function ospf_asbr_route_cmp is called uniquely from
ospf_route_cmp() when the flag OSPF_RFC1583_COMPATIBLE is not set.
Therefore, the check that the flag is set doesn't make sense at all
and it can consequently be removed without doing any harm.

* sockopt.c (getsockopt_ifindex): "ifindex" was never used
|
|
|
|
* ospf6_area.c: (ospf6_area_delete) Get rid of unused code that refers
to a nonexistent function and structure member.
|
|
* log.c: (closezlog) Also free the dynamically allocated filename when
a log is closed.
|
|
* bgp_route.c: (route_vty_out*) The local prefix, metric and weight values
are all stored as uint32_t. Change the format to %u so that large values
are not displayed as negative integers.
|
|
* ospf_{ism,network}.c: Certain oft-repeated but trivial messages should be
debug log level, not info, to avoid spamming 'terminal monitor'
|
|
* lib/prefix.c: (prefix_match) nano-optimisation, let it return early
without copying pointers.
|
|
|
|
Contains BGP fixes:
- set extcommunity crash: tihs patch tries to make the refcounting more robust
but does not fully solve the problem, sadly.
- BGP attribute error handling: Little testing.
|
|
* bgp_route.c: ({no_,}ipv6_bgp_network_ttl_cmd) depends on ipv6_bgp_network
which is HAVE_IPV6, so these should be too.
(bgp_route_init) and the installs should be similarly ifdefed
|
|
- SAFI value 3 is reserved. It was assigned by RFC 2858 for a use
that was never fully implemented, so it is deprecated by this
document.
* zebra.h: rename macro
* bgp_fsm.c: (bgp_graceful_restart_timer_expire,
bgp_graceful_stale_timer_expire, bgp_stop, bgp_establish): update
* bgpd.c: (peer_nsf_stop): update
* bgp_open.c: (bgp_capability_vty_out): SAFI 3 isn't a recognized case
any more

This change is based on Xavier Beaudouin's patch (which fixes detection
of 3 config.h macros on FreeBSD without any impact to Linux build of
Quagga) and FreeBSD port patch (which fixes 5 config.h macros, but
breaks the Linux build), it fixes 5 macros and works for both FreeBSD 8
and Linux.

Two macros resolving to the same integer constant broke a case block and
a more thorough merge of BGP_SAFI_VPNV4 and BGP_SAFI_VPNV6 was
performed.
* bgpd.h: MPLS-labeled VPN SAFI is AFI-independent, switch to single
* macro
* bgp_capability_test.c: update test data
* bgp_mp_attr_test.c: idem
* bgp_route.c: (bgp_maximum_prefix_overflow, bgp_table_stats_vty) update
macro and check conditions (where appropriate)
* bgp_packet.c: (bgp_route_refresh_send, bgp_capability_send,
bgp_update_receive, bgp_route_refresh_receive): idem
* bgp_open.c: (bgp_capability_vty_out, bgp_afi_safi_valid_indices,
bgp_open_capability_orf, bgp_open_capability): idem
* bgp_attr.c: (bgp_mp_reach_parse, bgp_packet_attribute,
bgp_packet_withdraw): idem
|
|
|
|
* bgpd.h: change value of BGP_SAFI_VPNV6 to 128 (RFC4659, BZ#659)
* bgp_route.c: (bgp_table_stats_vty) fix length argument to strncmp()
|
|
|
|
* ospf6_message.c: (ospf6_packet_max): new function, return maximum IPv6
payload on an interface; (ospf6_hello_send, ospf6_dbdesc_send,
ospf6_dbdesc_send_newone, ospf6_lsreq_send, ospf6_lsupdate_send_neighbor,
ospf6_lsupdate_send_interface, ospf6_lsack_send_neighbor,
ospf6_lsack_send_interface): compare message size with the maximum
payload instead of the MTU.
|
|
"mtu-ignore" is an option ospfd used to mimic from the vendor's
implementation, now ospf6d will also implement it.
* ospf6_interface.h: extend ospf6_interface structure by one flag
* ospf6_interface.c: (ipv6_ospf6_mtu_ignore, no_ipv6_ospf6_mtu_ignore):
new declarations; (ospf6_interface_create): show initial value for
consistency; (ospf6_interface_show): print flag status
* ospf6_message.c: (ospf6_dbdesc_recv): consider interface-specific flag
when checking MTU

* draft-ietf-idr-as-pathlimit doesn't seem to have gone anywhere, and its
author does not think it will make progress in IDR. Remove all support
introduced for it, but leave stubs for the commands to avoid breaking
any configurations.
Basically reverts cecab5e9725792e60a5e4b473e238a14cd85815d.

Conflicts:
bgpd/bgp_attr.c (caused by c8e7b895, resolved)
|

* bgp_attr.c: (bgp_attr_ext_communities) Certain extended-community attrs
can leave attr->flag indicating ext-community is present, even though no
extended-community object has been attached to the attr structure. Thus a
null-pointer dereference can occur later.
(bgp_attr_community) No bug fixed here, but tidy up flow so it has same
form as previous.
Problem and fix thanks to anonymous reporter.

...A nasty bug, if you forgot to disable debugging, stored the config
and reboot your machine - if you really depend on ripd, then the machine
will not fully come back on the network, because ripd fails.

* bgpd/bgp_debug.c: fix VTY strings for BGP debug commands to match
correct syntax
(cherry picked from commit 6e22b9017e1ae2ce61c383b1b2b63973207704ac)

* bgp_packet.c: (bgp_notify_receive) justify the difference between
BGP_NOTIFY_OPEN_UNSUP_PARAM and BGP_NOTIFY_OPEN_UNSUP_CAPBL cases, as
it is explained in RFC5492, page 3, paragraph 1.
"Unsupported Capability" error does not mean, that the peer doesn't
support capabilities advertisement -- quite the opposite (if the peer
would not support capabilities advertisement, the code would be
"Unsupported Optional Parameter"). Thus there is no reason to mark
the peer as one non-supporting capabilities advertisement.
Example: suppose the peer is in fact IPv6-only, but we didn't configure
anything address-family specific for it. Then, the peer would refuse
the session with "Unsupported Capability" code. If we internally set
the peer as non-supporting capabilities advertisement after that, we
will not be able to establish the session with it ever, even with a
fixed configuration -- IPv6-only BGP session cannot be established
without capabilities.
In practice an edge case would be seen as the same IPv6 peer working
with its "neighbor" block read from bgpd.conf, but not working, when
slowly input in "conf t" mode.

* ospf6_spf.c: Don't replace a node with another node with a lower
number of hops, instead get them from the queue in the correct
order. (Actually, the replacement crashed the ospf6d daemon
rather than worked.)
