f6e6c3b5a5 Fix IP_HDRINCL usage on FreeBSD 11
FreeBSD 11 changed endianity of ip_len field from host order to network
order. Also DragonFly BSD allegedly expects network order here.

Thanks to Olivier Cochard-Labbé for the patch.

d14f8c3c45 Netlink: MPLS routes in kernel
Anyway, Bird is now capable to insert both MPLS routes and MPLS encap
routes into kernel.

It was (among others) needed to define platform-specific AF_MPLS to 28
as this constant has been assigned in the linux kernel.

No support for BSD now, it may be added in the future.

4e276a8920 Merged multipath and single-path data structures.
Dropped struct mpnh and mpnh_*()
Now struct nexthop exists, nexthop_*(), and also included struct nexthop
into struct rta.

Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed
to distinguish between these two cases, RTD_DEVICE is equivalent to
IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw).

From now on, we also explicitely want C99 compatible compiler. We assume
that this 20-year norm should be known almost everywhere.

65d2a88dd2 RPKI protocol with one cache server per protocol
The RPKI protocol (RFC 6810) using the RTRLib
(http://rpki.realmv6.org/) that is integrated inside
the BIRD's code.

Implemeted transports are:
 - unprotected transport over TCP
 - secure transport over SSHv2

Example configuration of bird.conf:
  ...
  roa4 table r4;
  roa6 table r6;

  protocol rpki {
    debug all;

    # Import both IPv4 and IPv6 ROAs
    roa4 { table r4; };
    roa6 { table r6; };

    # Set cache server (validator) address,
    # overwrite default port 323
    remote "rpki-validator.realmv6.org" port 8282;

    # Overwrite default time intervals
    retry   10;         # Default 600 seconds
    refresh 60;         # Default 3600 seconds
    expire 600;         # Default 7200 seconds
  }

  protocol rpki {
    debug all;

    # Import only IPv4 routes
    roa4 { table r4; };

    # Set cache server address to localhost,
    # use default ports tcp => 323 or ssh => 22
    remote 127.0.0.1;

    # Use SSH transport instead of unprotected transport over TCP
    ssh encryption {
      bird private key "/home/birdgeek/.ssh/id_rsa";
      remote public key "/home/birdgeek/.ssh/known_hosts";
      user "birdgeek";
    };
  }

17fe57d8dc Log: Fix broken syslog name
BIRD passed string from configuration to openlog(), which kept it
internally. After reconfiguration the old string was freed, therefore
openlog had invalid copy.

6e75d0d27f KRT: Add krt_scope attribute
Add a new route attribute, krt_scope, to expose the Linux kernel route
scope. Constants from /etc/iproute2/rt_scopes (prefixed by "ips_") are
expected to be used with the attribute. Both import and export are
supported.

Also, the patch fixes device route export to the kernel, by setting link
scope automatically.

a290da25a1 rt-table: Fix kernel protocol export filter memory bug
Kernel protocol calls rt_export_merged(), which used @rte_update_pool for
temporary allocations, supposing it is called from other functions from
rt-table.c that handles locking and flushing of the linpool. Therefore,
linpool was not flushed properly and memory leaked.

Add linpool argument to rt_export_merged() and use @krt_filter_lp when
called from kernel protocol.

Thanks to Justin Cattle and Alexander Frolkin for the bugreport.

4adcb9df1b KRT: Add kernel metric protocol option
Kernel routes with different metrics do not clash with each other,
therefore using dedicated metric value is a reliable way to avoid
overwriting routes from other sources (e.g. kernel device routes).

Although kernel route metric could already be set as a route attribute by
filters, that is not consistent with the way how Linux kernel handles
route metric - not just a route attribute, but a part of a route key.

2feaa6931b KRT: Support for IPv6 ECMP
Linux represents IPv6 ECMP routes as a sequence of unipath routes with
the same prefix. We have to translate between our representation (one
route with multipath next hop) and the Linux representation in both
directions.

Proper learning of alien IPv6 ECMP routes still not supported.

Thanks to Mikhail Sennikovskii for the original patch.

f9f2e280ea KRT: Forbid path merging on BSD
We support ECMP routes only on Linux. Exported routes are checked in
krt_capable(), but a route generated during path merging avoids this
check.
