      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.

      Ondřej Zajíček authored
      Also significant core protocol state changes needed for that,
      global graceful restart recovery state and kernel proto support
      for recovery.

      Allows rejected routes to be kept and examined. · cf98be7b
      Ondřej Zajíček authored
      When 'import keep rejected' protocol option is activated, routes
      rejected by the import filter are kept in the routing table, but they
      are hidden and not propagated to other protocols. It is possible to
      examine them using 'show route rejected'.

      Implements ADD-PATH extension for BGP. · 094d2bdb
      Ondřej Zajíček authored
      Allows to send and receive multiple routes for one network by one BGP
      session. Also contains necessary core changes to support this (routing
      tables accepting several routes for one network from one protocol).
      It needs some more cleanup before merging to the master branch.

      Better support for multitable protocols. · c0adf7e9
      Ondřej Zajíček authored
      The nest-protocol interaction is changed to better handle multitable
      protocols. Multitable protocols now declare that by 'multitable' field,
      which tells nest that a protocol handles things related to proto-rtable
      interaction (table locking, announce hook adding, reconfiguration of
      filters) itself.
      Filters and stats are moved to announce hooks, a protocol could have
      different filters and stats to different tables.
      The patch is based on one from Alexander V. Chernikov, thanks.

      Implements protocol templates. · a7f23f58
      Ondřej Zajíček authored
      Based on the patch from Alexander V. Chernikov.
      Extended to support almost all protocols.
      Uses 'protocol bgp NAME from TEMPLATE { ... }' syntax.

      Many changes in (mainly) kernel syncers. · ff2857b0
      Ondřej Zajíček authored
      - BSD kernel syncer is now self-conscious and can learn alien routes
      - important bugfix in BSD kernel syncer (crash after protocol restart)
      - many minor changes and bugfixes in kernel syncers and neighbor cache
      - direct protocol does not generate host and link local routes
      - min_scope check is removed, all routes have SCOPE_UNIVERSE by default
      - also fixes some remaining compiler warnings

      Fixes a tricky bug in the pipe protocol. · c8387626
      Ondřej Zajíček authored
      When uncofiguring the pipe and the peer table, the peer table was
      unlocked when pipe protocol state changed to down/flushing and not to
      down/hungry. This leads to the removal of the peer table before
      the routes from the pipe were flushed.
      The fix leads to adding some pipe-specific hacks to the nest,
      but this seems inevitable.
