145368f547 Extends multipath support for OSPF.
Fixes cases where the same network or external route are propagated by
several OSPF routes and some other corner cases in next hop construction
and ECMP. Allows to specify whether external routes should be merged.

Thanks to Peter Christensen for the original patch.

48e5f32db6 Many changes in I/O and OSPF sockets and packet handling.
I/O:
 - BSD: specify src addr on IP sockets by IP_HDRINCL
 - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
 - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
 - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO
 - Alternative SKF_BIND flag for binding to IP address
 - Allows IP/UDP sockets without tx_hook, on these
   sockets a packet is discarded when TX queue is full
 - Use consistently SOL_ for socket layer values.

OSPF:
 - Packet src addr is always explicitly set
 - Support for secondary addresses in BSD
 - Dynamic RX/TX buffers
 - Fixes some minor buffer overruns
 - Interface option 'tx length'
 - Names for vlink pseudoifaces (vlinkX)
 - Vlinks use separate socket for TX
 - Vlinks do not use fixed associated iface
 - Fixes TTL for direct unicast packets
 - Fixes DONTROUTE for OSPF sockets
 - Use ifa->ifname instead of ifa->iface->name

70e212f913 Implements TTL security for OSPF and RIP.
Interfaces for OSPF and RIP could be configured to use (and request)
TTL 255 for traffic to direct neighbors.

ef4a50be10 Better packet priority and traffic class handling.
Implements support for IPv6 traffic class, sets higher priority for OSPF
and RIP outgoing packets by default and allows to configure ToS/DS/TClass
IP header field and the local priority of outgoing packets.

8df02847e8 Fixes a compatibility issue in OSPFv2 PtP links.
BIRD used zero netmask in hello packets on all PtP links, not just on
unnumbered ones. This patch fixes it and adds option 'ptp netmask'
for overriding the default behavior.

Thanks to Alexander V. Chernikov for the original patch.

9ff5257357 Better handling of global addresses as configured NBMA neighbors in OSPFv3.
Configured NBMA neighbors in OSPFv3 should be link-local addresses, old
behavior was to silently ignore global ones. The patch allows BIRD to
accept global ones, but adds a warning and a documentation notice.

Thanks to Wilco Baan Hofman for the bugreport.

0ea8fb4abe Fixes and enhancements in 'show ospf state' command.
Now it shows a distance, option to change showing reachable/all network
nodes and better handling of AS-external LSAs in multiple areas. The
command 'show ospf topology' was changed to not show stubnets in both
OSPFv2 and OSPFv3 (previously it displayed stubnets in OSPFv2).

- Adds bgp_originator_id and bgp_cluster_list route attributes.
 - Adds dotted quad filter datatype (for router IDs, used by
   bgp_originator_id and ospf_router_id route attributes).
 - Fixes pair ~ pair set matching.
 - Documentation updates.

c27b2449d1 Shows source (Router ID) for OSPF routes and adds such attribute.
A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.

20e94fb85b A change in OSPF and RIP interface patterns.
Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:

interface "eth3" { options ... }, "eth4" { options ... };

024c310b53 Fixes broken cryptographic authentication in OSPF
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.

That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

b21f68b4cd Fix bugs in OSPF MD5 authentication. First bug is that default
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.

It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

a3b70dc499 Two new informative CLI commands for OSPF.
Two new CLI commands for OSPF giving nice informative (and still machine
parsable) representation of OSPF network graph (based on datas from the
LSA database).

The first command (show ospf topology) shows routers, networks and stub
networks, The second command (show ospf state) shows also external
routes and area-external networks and routers propagated by given area
boundary router.
