      Basic VRF support · 943478b0
      Ondřej Zajíček authored
      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.

      KRT: Fix IPv6 ECMP handling with Linux 4.11+ · 98bb80a2
      Ondřej Zajíček authored
      Starting from Linux 4.11, IPv6 ECMP routes are now notified using
      RTA_MULTIPATH, like IPv4 ones. The patch adds support for RTA_MULTIPATH
      parsing for IPv6 routes. This also enables to parse ECMP alien routes
      correctly.
      
      Thanks to Vincent Bernat for the original patch.

      Implement onlink flag for nexthops · a1f5e514
      Ondřej Zajíček authored
      Add proper support for per-nexthop onlink flag in routes to handle next
      hop addresses that are not covered by interface IP ranges. Supported by
      kernel and static protocols.
      
      Thanks to Vincent Bernat for the idea.

      Replace integer type width detection with C99 fixed-width types.
      Also remove some unused or obsolete code.

      Netlink: MPLS routes in kernel · d14f8c3c
      Jan Moskyto Matejka authored
      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.

      Merged multipath and single-path data structures. · 4e276a89
      Jan Moskyto Matejka authored
      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.

      KRT: Add krt_scope attribute · 6e75d0d2
      Ondřej Zajíček authored
      Add a new route attribute, krt_scope, to expose the Linux kernel route
      scope. Constants from /etc/iproute2/rt_scopes (prefixed by "ips_") are
      expected to be used with the attribute. Both import and export are
      supported.
      
      Also, the patch fixes device route export to the kernel, by setting link
      scope automatically.

      KRT: Add kernel metric protocol option · 4adcb9df
      Ondřej Zajíček authored
      Kernel routes with different metrics do not clash with each other,
      therefore using dedicated metric value is a reliable way to avoid
      overwriting routes from other sources (e.g. kernel device routes).
      
      Although kernel route metric could already be set as a route attribute by
      filters, that is not consistent with the way how Linux kernel handles
      route metric - not just a route attribute, but a part of a route key.

      KRT: Support for IPv6 ECMP · 2feaa693
      Ondřej Zajíček authored
      Linux represents IPv6 ECMP routes as a sequence of unipath routes with
      the same prefix. We have to translate between our representation (one
      route with multipath next hop) and the Linux representation in both
      directions.
      
      Proper learning of alien IPv6 ECMP routes still not supported.
      
      Thanks to Mikhail Sennikovskii for the original patch.
