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.

5b208e296f Removing (struct rta)->cast. Never used. 2016-12-22 13:09:59 +01:00
Jan Moskyto Matejka
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";
    };
  }

261816b0d4 BGP: Cluster list item should be prepended 
Commit 3c09af41... changed behavior of int_set_add() from prepend to
append, which makes more sense for community list, but prepend must be
used for cluster list. Add int_set_prepend() and use it in cluster list
handling code.

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.

e86cfd41d9 KRT: Fix route learn scan when route changed 
When a kernel route changed, function krt_learn_scan() noticed that and
replaced the route in internal kernel FIB, but after that, function
krt_learn_prune() failed to propagate the new route to the nest, because
it confused the new route with the (removed) old best route and decided
that the best route did not changed.

Wow, the original code (and the bug) is almost 17 years old.

86b4e17001 Nest: Fixes bug in missing cleanup during table removal 
When a table is removed during reconfiguration, a reference was not
cleared in the old configuration, which breaks undo.

9b9a7143c4 Conf: Fixes bug in symbol lookup during reconfiguration 
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.

The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.

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.

The new RIP implementation fixes plenty of old bugs and also adds support
for many new features: ECMP support, link state support, BFD support,
configurable split horizon and more. Most options are now per-interface.
