2017-04-12Static: Support for dual-AF IGP tablesOndrej Zajicek (work)
When recursive routes with hybrid next hops (e.g. IPv6 route with IPv4 next hop) are allowed, we need both IPv4 and IPv6 IGP tables.
2017-03-29BGP: Simplify igp table optionsOndrej Zajicek (work)
2017-03-29BGP: Update list of supported standardsOndrej Zajicek (work)
2017-03-26BGP: Support for routes with mixed-AF next hopsOndrej Zajicek (work)
Covers IPv4/VPNv4 routes with IPv6 next hop (RFC 5549), IPv6 routes with IPv4 next hop (RFC 4798) and VPNv6 routes with IPv4 next hop (RFC 4659). Unfortunately it also makes next hop hooks more messy. Each BGP channel now could have two IGP tables, one for IPv4 next hops, the other for IPv6 next hops.
2017-03-22BGP: Support for MPLS labels and VPN SAFIOndrej Zajicek (work)
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.
2017-03-14BGP: Allow to specify interface for regular sessionsOndrej Zajicek (work)
This may be useful if multple interfaces share the same network range. Thanks to Fritz Grimpen for the original patch.

2016-12-07BGP: Add support for flowspec (RFC 5575)Ondrej Zajicek (work)
2016-12-07BGP redesignOndrej Zajicek (work)
Integrated and extensible BGP with generalized AFI handling, support for IPv4+IPv6 AFI and unicast+multicast SAFI.
2016-11-25BGP: Fix memory leak in graceful restart codeOndrej Zajicek (work)
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.

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.

2016-04-13BSD: 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.

2016-04-06IO: 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.
2016-02-11BGP: Fix bug in incoming connection handlingOndrej Zajicek (work)
When a BGP session was established by an outgoing connection with Graceful Restart behavior negotiated, a pending incoming connection in OpenSent state, and another incoming connection was received, then the outgoing connection (and whole BGP session) was closed, but the old incoming connection was just overwritten by the new one. That later caused a crash when the hold timer from the old connection fired.
2016-02-01Channels - explicit links between protocols and tablesOndrej Zajicek (work)
The patch adds support for channels, structures connecting protocols and tables and handling most interactions between them. The documentation is missing yet.
2015-07-18BGP: Extended messages supportOndrej Zajicek
Implements draft-ietf-idr-bgp-extended-messages-10, for now undocumented and with temporary private capability number.
2015-06-08BGP multipath supportOndrej Zajicek
Kernel option 'merge paths' allows to merge routes exported to kernel protocol (currently BGP and static routes) to multipath routes.
2015-03-29BGP: Enhanced route refresh (RFC 7313) supportOndrej Zajicek
Also hook feed_done is renamed to feed_end.
2015-02-22Rename BGP option 'start delay' to 'connect delay'Ondrej Zajicek
Also update log message for error-triggered startup delay.
2015-02-22Relax BGP neighbor parameterOndrej Zajicek
Permit specifying neighbor address, AS number and port independently. Add 'interface' parameter for specifying interface for link-local sessions independently. Thanks to Alexander V. Chernikov for the original patch.
2015-02-21Store protocol config size inside protocol structureOndrej Zajicek
Make proto_config_new() use this info instead of supplied size. Thanks to Alexander V. Chernikov for the patch.
2015-02-21Make BGP protocol instance search a separate functionOndrej Zajicek
Thanks to Alexander V. Chernikov for the patch.

2013-11-24Enables multihop mode for IBGP by default.Ondrej Zajicek
This is more consistent with common usage and also with the behavior of other implementations (Cisco, Juniper). Also changes the default for gw mode to be based solely on direct/multihop.

2013-08-13Fixes a bug related to mixed up neighbor events in BGP.Ondrej Zajicek
Neighbor events related to received route next hops got mixed up with sticky neighbor node for an IP of the BGP peer. If a neighbor for a next hop disappears, BGP session is shut down.
2013-07-13Fixes stuck connection during BGP session shutdown.Ondrej Zajicek
If TX buffers were full during BGP session shutdown then a protocol waited indefinitely to be able to send notification packet to close the session.
