2016-12-22Static: Protocol rework wrt. struct nexthop changes; MPLS label supportJan Moskyto Matejka
2016-12-22Nexthop: Support for label stack in nestJan Moskyto Matejka
2016-12-22Removing (struct rta)->cast. Never used.Jan Moskyto Matejka
2016-12-22Merged multipath and single-path data structures.Jan Moskyto Matejka
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.

2016-12-07RPKI protocol with one cache server per protocolPavel Tvrdík
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"; }; } ...

2016-11-01Build: switch on -Wextra, get rid of most of the warningsJan Moskyto Matejka
There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.
2016-10-27IANA assigned a different number to large BGP communities - changed.Ondrej Filip
2016-10-03BGP: Support for large communitiesOndrej Zajicek (work)
Add support for large communities (draft-ietf-idr-large-community), 96bit alternative to RFC 1997 communities. Thanks to Matt Griswold for the original patch.
2016-09-15BFD: Fix invalid read from pollfd arrayPavel Tvrdik
It is possible that sockets_add() are called between sockets_prepare() and sockets_fire() during poll loop in birdloop_main(), so we need to use loop->poll_fd.used instead of loop->sock_num to find the last field.
2016-09-14Nest: Keep multipath next hops sortedOndrej Zajicek (work)
2016-07-20Babel: Immediately update hello interval on interface reconfigureOndrej Zajicek (work)
An interface reconfiguration may change both the hello and update intervals. An update interval change is immediately put into effect, while a hello interval change is not. This also updates the hello interval immediately (if the new interval is shorter than the old one), and sends a hello to notify peers of the change.

2016-07-19Babel: Do not maintain feasibility distance for our own routesOndrej Zajicek (work)
We do not need to maintain feasibility distances for our own router ID (we ignore the updates anyway). Not doing so makes the routes be garbage collected sooner when export filters change. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19Babel: Do not keep an infeasible route as selectedOndrej Zajicek (work)
When a route becomes infeasible it should not be kept as selected; this is forbidden by section 3.6 of the RFC and prevents subsequent updates from the same router ID from replacing it. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19Babel: Send wildcard retractions on shutdown and startupOndrej Zajicek (work)
This makes BIRD send a wildcard retraction on all interfaces before shutting down and right after starting up. This helps ensure that neighbours will discard the announced routes as soon as possible, rather than only after the normal timeout procedures. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19Babel: Rework handling of retractionsOndrej Zajicek (work)
An update with wildcard AE and infinite metric should be treated as a global retraction of all prefixes announced by that neighbour, per section 4.4.9 of the RFC. In addition, router ID and seqno in retraction updates should be ignored. This reworks the handling of retractions and adjusts the parser to handle all this correctly. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19Babel: Make sure intervals do not overflowOndrej Zajicek (work)
Intervals are carried as 16-bit centisecond values, but kept internally in 16-bit second values, which causes a potential for overflow. This adds some checks to make sure this does not happen. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-11BGP: Fix extended messagesOndrej Zajicek (work)
Change attribute length limit to handle extended (64 kB) messages. Do not mix updates and withdraws (RFC 7606).
2016-06-29BGP: Skip empty path segments in received AS_PATHOndrej Zajicek (work)
Although RFC 4271 does not forbid empty path segments, they are useless and some implementations consider them invalid. It is clarified in RFC 7606, specifying that AS_PATH with empty segment is considered malformed.
2016-05-17IO: Minor changes in socket AF handingOndrej Zajicek (work)
AF can be specified implicitly by saddr or daddr, flags SKF_V4ONLY and SKF_V6ONLY are to be removed.

2016-05-10Build system reworked to one global Makefile with includes and no nestingJan Moskyto Matejka
Also removed the lib-dir merging with sysdep. Updated #include's accordingly. Fixed make doc on recent Debian together with moving generated doc into objdir. Moved Makefile.in into root dir Retired all.o and birdlib.a Linking the final binaries directly from all the .o files.
2016-04-28Add the Babel routing protocol (RFC 6126)Ondrej Zajicek (work)
This patch implements the IPv6 subset of the Babel routing protocol. Based on the patch from Toke Hoiland-Jorgensen, with some heavy modifications and bugfixes. Thanks to Toke Hoiland-Jorgensen for the original patch.
2016-04-13BSD: Add the IPsec SA/SP database entries controlOndrej Zajicek (work)
Add code for manipulation with TCP-MD5 keys in the IPsec SA/SP database at FreeBSD systems. Now, BGP MD5 authentication (RFC 2385) keys are handled automatically on both Linux and FreeBSD. Based on patches from Pavel Tvrdik.
2016-04-08Route update: move table lookup from protocols into rte_update2().Jan Moskyto Matejka
Many protocols do almost the same when creating a rte_update request before calling rte_update2(). This commit should simplify the protocol side of the route-creation routine.

2016-04-07Channelize: rt_notify arg conversion table -> channelJan Moskyto Matejka
2016-04-06IO: Avoid multiple event cycles in one loop cycle.Ondrej Zajicek (work)
Event cycle may took too much time and trigger next timer events, so avoid cycling between timer and event cycles inside the loop cycle.
2016-04-06IO: Replace RX priority heuristic with explicit markOndrej Zajicek (work)
In BIRD, RX has lower priority than TX with the exception of RX from control socket. The patch replaces heuristic based on socket type with explicit mark and uses it for both control socket and BGP session waiting to be established. This should avoid an issue when during heavy load, outgoing connection could connect (TX event), send open, but then failed to receive OPEN / establish in time, not sending notifications between and therefore got hold timer expired error from the neighbor immediately after it finally established the connection.
2016-03-23Birdlib: Do cleanups after remove/freeOndrej Zajicek (work)
To avoid byzantine behavior in case of some errors, linked lists are cleared after rem_node() and resource headers are cleared after rfree().
2016-03-23OSPF: Fix bogus LSA ID collisions between received and originated LSAsOndrej Zajicek (work)
After restart, LSAs locally originated by the previous instance are received from neighbors. They are installed to LSA db and flushed. If export of a route triggers origination of a new external LSA before flush of the received one is complete, the check in ospf_originate_lsa() causes origination to fail (because en->nf is NULL for the old LSA and non-NULL for the new LSA). The patch fixes this by updating the en->nf for LSAs being flushed (as is already done for empty ones). Generally, en->nf field deserves some better description in the code. Thanks to Jigar Mehta for analyzing the problem.
