2018-02-13Add support for source-specific IPv6 routes to BIRD coreOndrej Zajicek (work)
This patch adds support for source-specific IPv6 routes to BIRD core. This is based on Dean Luga's original patch, with the review comments addressed. SADR support is added to network address parsing in confbase.Y and to the kernel protocol on Linux. Currently there is no way to mix source-specific and non-source-specific routes (i.e., SADR tables cannot be connected to non-SADR tables). Thanks to Toke Hoiland-Jorgensen for the original patch. Minor changes by Ondrej Santiago Zajicek.

2017-12-07Printf: Add support for microsecond timesOndrej Zajicek (work)
Use '%t' in bsnprintf() for microsecond times (in btime) with variable sub-second precision.
2017-12-07Timers: Parse and format functions for microsecond timesOndrej Zajicek (work)
Date/time output (e.g. in logs, show commands) can use %f to specify subsecond time. By default, millisecond precision is used in output.
2017-12-07Timers: Replace old timers with microsecond timersOndrej Zajicek (work)
The old timer interface is still kept, but implemented by new timers. The plan is to switch from the old inteface to the new interface, then clean it up.

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.

Replaced by constant compile-time expressions. CPU_STRUCT_ALIGN is not really correct, but is consistent with the old behavior.

2017-03-28Simpler format of VPN RDJan Moskyto Matejka
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.

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

2017-03-09Static: Minor overhaulOndrej Zajicek (work)
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.

2016-12-22VPN4 and VPN6 literalsJan Moskyto Matejka
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).
2016-12-22Netlink: MPLS routes in kernelJan Moskyto Matejka
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.
