  other than the netname.
- Export NETNAME, DEVICE and INTERFACE environment variables to scripts.

b6298e2c08 - More changes needed for Kruskal's algorithm 
- Implemented a breadth-first search algorithm as a cheap substitution for a
  single-source shortest path algorithm.

82e3837109 Big bad commit: 
- Transition to new node/vertex/connection structures
- Use new configuration handling everywhere
- Linux tun/tap device handling cleanup
- Start of IPv6 support in route.c

It compiles, but it won't link.

21027b1d57 - Renamed lastbutonehop to prevhop. 
- Added connection_t *via to connection_t, this keeps record of where
  to send UDP packets to.
 2001-10-08 11:47:55 +00:00

24a2c7e51a Not only keep track of nexthop, but also of lastbutonehop. If destination cl 
wants indirectdata, send it to the lastbutonehop instead, unless it too has
requested so, and so on.

ef1facc607 Remove IndirectData support for now, new implementation will be added 
later.

12f6b80429 Added purge_tree for connection_t's which are no longer in the connection, 
active or id trees, but which may still be referenced. This tree is flushed
when it is safe, this replaces purge_connection_tree().

Also lots of bugfixes related to the new trees.

319e0cb48e Split connection list into two lists: 
- one list to handle all incoming/outgoing TCP connections
 - another list to handle all UDP connections

This will prevent race conditions.

4f9dad0972 - tinc can now act as a switch or a hub too (as opposed to a router only) 
- cleaner initialisation of "UNKNOWN" and "MYSELF" names

  is not useful anyway.
