2019-04-03BGP: Promiscuous ASN modeOndrej Zajicek (work)
Allow to specify just 'internal' or 'external' for remote neighbor instead of specific ASN. In the second case that means BGP peers with any non-local ASNs are accepted.

2019-03-19BGP: Mandatory option for channelsOndrej Zajicek (work)
Allow to mark channel to be mandatory, and do not allow BGP sessions if no common AFI/SAFI is established.

2018-12-18Perf: Protocol to measure BIRD performance internallyMaria Matějka
This protocol is highly experimental and nobody should use it in production. Anyway it may help you getting some insight into what eats so much time in filter processing.
2018-12-16BGP: Extend 'next hop keep' and 'next hop self' optionsOndrej Zajicek (work)
Extend 'next hop keep' and 'next hop self' options to have boolean values (enabled / disabled) and also values 'ibgp'/ 'ebgp' to restrict it to routes received from IBGP / EBGP. This allows to have it enabled by default in some cases, matches features of other implementations, and allows to handle some strange cases like EBGP border router with 'next hop self' also doing IBGP route reflecting. Change default of 'next hop keep' to enabled for route servers, and 'ibgp' for route reflectors. Update documentation for these options.

2018-12-06Custom route attributesMaria Matejka
For local route marking purposes, local custom route attributes may be defined. These attributes are seamlessly stripped after export filter to every real protocol like Kernel, BGP or OSPF, they however pass through pipes. We currently allow at most 256 custom attributes. This should be much faster than currently used bgp communities for marking routes.
2018-12-04Unix: Change debugging optionsOndrej Zajicek (work)
The old behavior was that enabling debugging did many nontrivial changes in BIRD behavior. The patch changes it that these changes are generally independent. Compiling with --enable-debug now just enables compile-time debug macros, but do not automatically activate debug mode (-d) nor local mode (-l). Debug mode with output to file (-D) do not force foreground mode (-f), therefore there is no need for backgroud option (-b), which is removed. Also fixes a bug when the default log target in -D mode was stderr instead of given debug file.

2018-11-05Filter: Make ifname attribute modifiableOndrej Zajicek (work)
Allow to change an interface associated with a route by setting ifname attribute. It will also change the route to a direct one.

Thanks to Clemens Schrimpe for the bugreport.
2018-08-21DOC: Remove pipe mode referenceOndrej Zajicek (work)
Pipe mode was removed in 2.0, remove reference to it in the documentation. Thanks to Piotr Wydrych for the bugreport.

Thanks to Julien Dessaux for the report.
2018-07-31BGP: Long-lived graceful restartOndrej Zajicek (work)
The patch implements long-lived graceful restart for BGP, namely draft-uttaro-idr-bgp-persistence-03.
2018-05-24Do not initialize route metrics in import_control hookOndrej Zajicek (work)
During route export, the receiving protocol often initialized route metrics to default value in its import_control hook before export filter was executed. This is inconsistent with the expectation that an export filter would process the same route as one in the routing table and it breaks setting these metrics before (e.g. for static routes directly in static protocol). The patch removes the initialization of route metrics in import_control hook, the default values are already handled in rt_notify hook called after export filters. The patch also changed the behavior of OSPF to keep metrics when a route is reannounced between OSPF instances (to be consistent with other protocols) and the behavior when both ospf_metric1 and ospf_metric2 are specified (to have more expected behavior).
2018-05-03Babel: Add option to randomize router IDOndrej Zajicek (work)
When a Babel node restarts, it loses its sequence number, which can cause its routes to be rejected by peers until the state is cleared out by other nodes in the network (which can take on the order of minutes). There are two ways to fix this: Having stable storage to keep the sequence number across restarts, or picking a different router ID each time. This implements the latter, by introducing a new option that will cause BIRD to randomize a high 32 bits of router ID every time it starts up. This avoids the problem at the cost of not having stable router IDs in the network. Thanks to Toke Hoiland-Jorgensen for the patch.

To comply with RFC 8212 requirements.

Multiple definitions of same channels are forbidden, but inherited channel can be redefined. In such case channel options are merged.

2017-09-06Basic VRF supportOndrej Zajicek (work)
Add basic VRF (virtual routing and forwarding) support. Protocols can be associated with VRFs, such protocols will be restricted to interfaces assigned to the VRF (as reported by Linux kernel) and will use sockets bound to the VRF. E.g., different multihop BGP instances can use diffent kernel routing tables to handle BGP TCP connections. The VRF support is preliminary, currently there are several limitations: - Recent Linux kernels (4.11) do not handle correctly sockets bound to interaces that are part of VRF, so most protocols other than multihop BGP do not work. This will be fixed by future kernel versions. - Neighbor cache ignores VRFs. Breaks config with the same prefix on local interfaces in different VRFs. Not much problem as single hop protocols do not work anyways. - Olock code ignores VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. - Incoming BGP connections are not dispatched according to VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. Perhaps we would need some kernel API to read VRF of incoming connection? Or probably use multiple listening sockets in int-new branch. - We should handle master VRF interface up/down events and perhaps disable associated protocols when VRF goes down. Or at least disable associated interfaces. - Also we should check if the master iface is really VRF iface and not some other kind of master iface. - BFD session request dispatch should be aware of VRFs. - Perhaps kernel protocol should read default kernel table ID from VRF iface so it is not necessary to configure it. - Perhaps we should have per-VRF default table.
