      IO: Replace RX priority heuristic with explicit mark · 9e7b3ebd
      Ondřej Zajíček authored
      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.

      Many changes in I/O and OSPF sockets and packet handling. · 48e5f32d
      Ondřej Zajíček authored
      I/O:
       - BSD: specify src addr on IP sockets by IP_HDRINCL
       - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
       - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
       - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO
       - Alternative SKF_BIND flag for binding to IP address
       - Allows IP/UDP sockets without tx_hook, on these
         sockets a packet is discarded when TX queue is full
       - Use consistently SOL_ for socket layer values.
      
      OSPF:
       - Packet src addr is always explicitly set
       - Support for secondary addresses in BSD
       - Dynamic RX/TX buffers
       - Fixes some minor buffer overruns
       - Interface option 'tx length'
       - Names for vlink pseudoifaces (vlinkX)
       - Vlinks use separate socket for TX
       - Vlinks do not use fixed associated iface
       - Fixes TTL for direct unicast packets
       - Fixes DONTROUTE for OSPF sockets
       - Use ifa->ifname instead of ifa->iface->name

      Workaround for stupid callback scheduler. · ea89da38
      Ondřej Zajíček authored
      There is no reak callback scheduler and previous behavior causes
      bad things during hard congestion (like BGP hold timeouts).
      
      Smart callback scheduler is still missing, but main loop was
      changed such that it first processes all tx callbacks (which
      are fast enough) (but max 4* per socket) + rx callbacks for CLI,
      and in the second phase it processes one rx callback per
      socket up to four sockets (as rx callback can be slow when
      there are too many protocols, because route redistribution
      is done synchronously inside rx callback). If there is event
      callback ready, second phase is skipped in 90% of iterations
      (to speed up CLI during congestion).
