b55f945133 fixed packet dequeue bug (mdp ping has no duplicate replies now). 
cleaned up debug output.

2581e9fe4c Revamped dequeuing of TXd frames. 
Now almost works (queues don't stay full of junk), although
mdp ping still gets a duplicate reply for 2-hop pings.

c37d83bddd forwarding of overlay frames substantially in place, but requires 
testing.

unicast frames at the right time.

283b29af6b Improved packet tx and rx debugging and made it more logical. 2012-04-14 06:38:11 +09:30

167c59d50d Added debug option to suppress rhizome traffic to make it easier 
to see what is going on.
Similarly there is now a debug option to show outgoing packets.

0cb3e6e60b Added code to properly direct both broadcast and unicast packets 
to the correct interface(s).  An issue with the node lookup is
preventing it from working at present, however.

6759a26720 Cleaned out some debugging output after tracking down and fixing 
memory corruption bug.  Next challenge is to find out why broadcast
MDP packets are not getting dispatched properly (is trying to treat
broadcast address as unicast address it seems).

13d1d3084e Various fixes to track down memory handling bugs. 
Fixed one free-before-time bug with queuing MDP frames.
Some heap corruption bug seems to remain.

c7dd475d50 Further work on MDP, including dispatching low-priority data when 
it can fit in frames.  A nasty bug in queue code needs fixing.
Also, we only send tick frames at present, and need to add code
for dispatching packets at other times (bandwidth allowance permitting).
So the whole bandwidth management code needs to get finished.

70497df7b5 More work on MDP. Removed some debug fluff. 
Added framework for MDP ping, and some work towards MDP port binding
and sending packets with option to wait for reply.  MDP server
doesn't yet support port binding, and client doesn't yet support
reading replies.

1eb4c34015 Renamed mphlr.h to serval.h

6397fa70d9 overlay interface file descriptors now marked close-on-exec so that 
if we get a sigabort or segmentation violation and restart ourselves,
we don't wind up with stuck/lost sockets.

5cc6079c0f Move from recvfrom() to recvmsg() so that we can get packet TTLs on 
reception.  Other changes associated with overlay mesh.

bf9f8559f1 Various debug fiddles and conversion from select() to poll()

44c0765981 Various debugging code cleanups.

fully known).
There is still a bug in dequeuing packets though it seems.

ba645687f6 Progress towards overlay mode advertising rhizome bundles.

b6ce25ab24 Believe I have found and stemmed the memory corruption bug, although

cbb1939241 Fixed various compiler warnings. 
Change overlay_frame payload to use an overlay_buffer structure for
consistency and ease of payload construction.
Added some sanity checking to peer score calculation.
Getting closer to being able to TX acks to selfannouncements.
Other little things to accomplish these.

b075b51c43 Merged overlay_payload and overlay_frame structures to just overlay_frame

Improved payload length encoding scheme to be shorter for most payload
lengths.
selfannouncement frames now get directed to stub functions for
implementation.

cf778e1efd Various further work on overlay mesh.

ec1fe22e93 Added support for using a dummy interface to allow testing of multiple mesh 
nodes on the same machine.  Also handly for linking to unusual interfaces
such as the UHF radio dongles we are planning.

c8229c8517 More work towards handling overlay or DNA packets. 
handling of sender address and sockets to use is still a big fat mess

2ff8541049 Woot! overlay mode now emits regular tick frames on interfaces it knows about. 
Still doesn't know about broadcast properly or a pile of other things, oh, and
the frames are completely empty, but none the less, we are now sending frames.

6e172c76c9 Fixed broadcast address discovery to work on Mac. 
Fixed Linux assumptions.
Added parsing of overlay mesh interface specification from command line.

Overlay mesh is still far from working, but the infrastructure is coming together.
