Ondrej Zajicek (work) b845ea097c Remove autoconf macros for time_t and alignment 
Replaced by constant compile-time expressions. CPU_STRUCT_ALIGN is not
really correct, but is consistent with the old behavior.

Ondrej Zajicek (work) 1e37e35c3e BGP: Support for MPLS labels and VPN SAFI 
Basic support for SAFI 4 and 128 (MPLS labeled IP and VPN) for IPv4 and
IPv6. Should work for route reflector, but does not properly handle
originating routes with next hop self.

Based on patches from Jan Matejka.

BTW, 'prefices' is hypercorrection, as 'prefix' is from 'praefixum' with
plural 'praefixa'.

Ondrej Zajicek (work) 7126cadf80 Static: Minor overhaul 
The patch fixes several bugs introduced in previous changes, simplifies
the protocol by handing routes uniformly, introduces asynchronous route
processing to avoid issues with separate notifications for each next-hop
in ECMP routes, and makes reconfiguration faster by avoiding quadratic
complexity.

Jan Moskyto Matejka d311368bc5 VPN4 and VPN6 literals 
From now on, protocol static accepts VPN4 and VPN6 addressess.
With some concerns about VPN6 Route Distinguishers, I finally chose
to have the same format as for VPN4 (where it is defined by RFC 4364).

Jan Moskyto Matejka 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.

Pavel Tvrdík 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";
    };
  }

Ondrej Zajicek (work) ed1a908e53 BGP: Fix memory leak in graceful restart code 
Prefix and bucket tables are initialized when entering established state
but not explicitly freed when leaving it (that is handled by protocol
restart). With graceful restart, BGP may enter and leave established
state multiple times without hard protocol restart causing memory leak.

Ondrej Zajicek (work) 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.

Thanks to Chris Caputo for the original patch.
