   3 - IPv6: hashing functions etc.
   4
   5 - krt-iface: check whether the interface alias hack works
   6
   7 - better memory allocators
   8 - real attribute cache
   9 - real neighbor cache
  10
  11 - preferences of protocols
  12
  13 - static: check validity of route destination?
  14 - static: allow specifying a per-route filter program for setting route attributes?
  15
  16 - rte_update: check whether all bits not covered by masklen are zero
  17 - rte_update: debug mode
  18
  19 - netlink: import Linux route attributes to our rta's, so that they can be filtered?
  20
  21 - config: when parsing prefix, check zero bits
  22
  23 - krt: rescan interfaces when route addition fails?
  24
  25 - tagging of external routes?
  26
  27 - io: use poll if available

  29 Commands
  30 ~~~~~~~~
  31 - showing of routing table as seen by given protocol
  32
  33 Documentation
  34 ~~~~~~~~~~~~~
  35 - write doctool
  36 - write documentation :|
  37
  38 Globals
  39 ~~~~~~~
  40 - right usage of DBG vs. debug
  41 - cleanup debugging calls
  42 - logging and tracing; use appropriate log levels
  43 - check incoming packets and log errors!!
  44 - check log calls for trailing newlines
  45 - check if all protocols set proper packet priorities and TTL's.
  46 - replace all NUM, IPA and expr tokens by constant filter expressions
  47 - try compiling with -Wunused
  48 - does everybody test return value of sk_open?
  49 - doc: references to RFC's we did follow
  50 - protocols: implement CLI hooks and per-procotol CLI commands
  51 - protocols: implement reconfigure hook
  52 - protocols: use locking
  53
  54 Various ideas
  55 ~~~~~~~~~~~~~
  56 - config: executable config files
  57 - client: access control
  58 - IPv6 router advertisements
  59 - real multipath (doesn't seem to be simple at all :()
  60 - fake multipath (even less simple)
  61 - route recalculation timing and flap dampening [see RFC2439 for algorithms]
  62 - aggregate engine: standard route aggregation and summarization [RFC2519]
  63 - aggregate engine: injection of manually configured pseudo-static routes
  64 - generate default route if any working BGP connection exists (aggregate engine again?)
  65 - generate default route to IGP's (aggregate engine yet another time?)
  66 - look at RFC 2386 (QoS-based routing)

  69 RIP
  70 ~~~
  71
  72 OSPF
  73 ~~~~
  74         - refuse running on non-multicast devices
  75         - importing of device routes for networks where we don't run OSPF
  76         - check incoming packets using neighbor cache
  77         - RFC2328 appendix E: Use a better algorithm
  78         - automatic generation of external route tags (RFC1403)
  79         - RFC1587 NSSA areas
  80         - RFC2370 opaque LSA's
  81         - respect interface MTU and try not to create larger packets unless unavoidable
  82
  83 BGP
  84 ~~~
  85         - aggregation, ATOMIC_AGGREGATE
  86         - communities
  87         - attributes must be sorted!
  88         - re-export of NEXT_HOP attribute
  89         - BGP session over currently down interface
  90         - LOCAL_PREF attribute
  91         - error notification received -> log error
  92         - set TTL to 1 (configurable?)
  93         - consulting IGP for next-hop information? (what if it changes?)
  94         - inter-advertisement delay???!
  95         - normalize (sort) incoming AS-SET's
  96         - maximum length of AS paths
  97         - expected neighbor AS
  98         - hold time
  99         - idle timer after error: initial value, exponential growth, maximum value
 100         - import of IGP routes (use external route tags from OSPF)
 101         - Use IP_RECVERR for BGP TCP sockets?
