Ondrej Zajicek (work) f4a60a9bc4 Channels - explicit links between protocols and tables
The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.

Jan Moskyto Matejka d7661fbe9d Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AF
Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listen
on v6, without setting the V6ONLY flag to catch both v4 and v6 traffic.

Ondrej Zajicek (work) fe9f1a6ded Initial commit on integrated BIRD
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.

The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.

Comments are welcome.

Ondrej Zajicek ef3cac669c OSPF: Fixes handling of external routes with immediate gw
The bug caused that received external LSAs with locally reachable
next hops were ignored. I wonder why nobody noticed it sooner.

Ondrej Zajicek 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.

Ondrej Zajicek 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

Ondrej Zajicek f623ab9875 Implements OSPF stub router option (RFC 3137).
Also fixes OSPFv3 routing table calculcation w.r.t.

Ondrej Zajicek 094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

If there was the same configured stubnet on local and remote
router, the remote route always won regardless of its cost.

Ondrej Zajicek 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).

- important bugfix in BSD kernel syncer (crash after protocol restart)

- direct protocol does not generate host and link local routes
- min_scope check is removed, all routes have SCOPE_UNIVERSE by default

Ondrej Zajicek 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.
