Maintain router LSA positions in OSPF interface.
Find the OSPF interface in nexthop_calculation using
the position in the router LSA.
This has the following advantages:
- Multiple numbered PtP interfaces with the same IP address
between the same two routers.
- Use Unnumbered PtP on just one end of the link.
- Faster OI lookup for the OSPF interface and only
done once for PtoP links.
*ospf_interface.h: (struct ospf_interface) Add storage for
storing router LSA position.
*ospf_interface.c: (ospf_if_lookup_by_lsa_pos)
lookup OSPF I/F in an area using LSA position.
(ospf_lsa_pos_set) assign LSA position to OSPF
interface.
*ospf_lsa.c: (router_lsa_link_set) Call ospf_lsa_pos_set() to record
LSA position.
*ospf_spf.c: (ospf_spf_next) Count and pass along lsa position.
(ospf_nexthop_calculation) Add lsa position argument.
call ospf_if_lookup_by_lsa_pos() for OSFP interface handle.
Clean up and remove all calls ospf_if_is_configured() the
rest. Adjust a few debug logs.

Add support for real unnumbered PtP interfaces in
ospf_nexthop_calculation().
Add ospf_if_lookup_by_ifindex() to support Unnumbered
PtP links. This version does not support:
- Multiple numbered PtP interfaces with the same IP address
between the same two routers.
- Unnumbered PtP on just one end of the link.
* ospfd/ospf_interface.c: Add ospf_if_lookup_by_ifindex().
* ospfd/ospf_interface.h: ditto.
* ospfd/ospf_spf.c: ospf_nexthop_calculation (), call
ospf_if_lookup_by_ifindex() for Unnumbered
PtP links.

Well, what I'm curious about is how you don't see a similar issue
with non-AS-external routes? Indeed, I wonder why we can't just apply
your check much earlier - as/when we add routes to the intra-area
routing table - and just get rid of that complete_direct_routes thing
altogether.

So would this perhaps fix it too (and if so, possibly fix similar
issues with other kinds of routes too)?:
REPLACES "External routes over PtoP must be directly connected."
by Joakim Tjernlund
As all locally routes over PtoP interfaces are interface routes,
one must also make sure that external routes over PtoP interfaces
are directly connected.

Freeing the area resets all LSAs seq number. Wait
until the area has no more configured interfaces before freeing
it. PPP intefaces are usally deleted when they go down and created
again when the come up. Avoid freeing the area and resetting
the seq number due to number of active interfaces drops to
zero temporairly.

Use with interface command:
interface ppp0
ip ospf area 0.0.0.0
This will enable OSPF on ppp0 with area 0.0.0.0
Remove with "no ip ospf area"

According to Acee Lindem, chairing the OSPF WG on IETF,
one should not transmit Option 1 as described in 12.4.1.1.
The text is unfortunately a bit unclear but the intention
of the spec was not to emit Option 1 (nor Option 2)

According to RFC 2328, section 10.5 PointToPoint neighbors
should be identified by router ID instead of source IP address.

ospf_snmp.c uses ospf_neighbor->address and still has the route_nodes
list code. fix it up to match current code.
|
| | | | | | | | |
| | | | | | | |
| | | | | | | |

address is the same as src so it is redundant.
This will save both memory and CPU when processing Hellos.

ospf_opaque.c needs to be updated for moving from route_node to a
regular list.
|
| | | | | | | | |
| | | | | | | |
| | | | | | | |
| | | | | | | |

It is wasteful to use route nodes for something
as simple as a neighbor list.
Replace with a list.

ospf_nbr_lookup_by_addr() included routerID while searching.
That is not the intention of this function so change it
to only search for IP addresses.

Add static host routes into router LSA.
See RFC 2328 chapter 12.4 and Appendix C.7
Syntax:
router ospf
ip ospf host A.B.C.D area (A.B.C.D|<0-4294967295>|all) cost <0-65535>
no ip ospf host A.B.C.D area (A.B.C.D|<0-4294967295>|all)
* ospfd/ospf_route.h: Add struct ospf_host_route
* ospfd/ospf_lsa.c: (router_lsa_link_set) Add host routes to Router LSA.
* ospfd/ospf_vtc.c: Impl. ip_ospf_host_cmd and no_ip_ospf_host_cmd.
(ospf_config_write) Write out host routes to config.
* ospfd/ospf_ospfd.c: (ospf_new) Allocate new host route list.
(ospf_finish_filnal) Free host list.
(ospf_area_check_free) Check if any host routes in
area before freeing.
* ospfd/ospf_ospfd.h: Add a host list to struct ospf.

This looks fishy in ospf_make_md5_digest()
if (list_isempty (OSPF_IF_PARAM (oi, auth_crypt)))
auth_key = (const u_int8_t *) "";
...
MD5Update(&ctx, auth_key, OSPF_AUTH_MD5_SIZE);
auth_key points to a "" string of len 1 which is a lot
smaller that OSPF_AUTH_MD5_SIZE. Is this intentional to
get some random data or just a plain bug?
Anyone using MD5 should have a closer look and decide
what to do.
