78a8aaca16 Code improvements while debugging 'dnaprotocol' tests 
Use ssize_t and size_t where required by system calls
More stringent checking of errors from system calls
Log the offset when writing to dummy interface file
Clean up many WHY/INFO/DEBUG statements
Convert many fprintf(stderr,...) to DEBUGF()

3b6a004cc9 new event scheduler almost working, but after a while can stop 
calling overlay_check_ticks alarm for some reason, which causes
queues to congest and bad things to generally happen.

7b520e7a49 fixed various bugs with priorty dispatch of voice traffic. 
some debug tweaking etc.
 2012-05-07 08:31:53 +09:30

6ee271d767 dispatch voice packets immediately on reception, and also flush 
any other queues that are banked up.  not an ideal implementation
of these, but is a start.

c9863fe11e lots of fixes to get overlay mesh routing working on linux with 
real network interfaces and no dummy interfaces.  neighbour discovery
now seems to work.

92baae2a89 hopefully fixed acking of self-announcement frames when no route 
to node exists.

e7e8b2d630 fixed bug in RFS size patching. 
A lot of debug output tweaks to track the problem down.

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

7928de5b01 Fixed broadcast address and BPI handling for address abbreviation 
and propagation.

f972c988b9 Adding support for marking payloads as broadcast so that they can 
be directed to all interfaces if they are broadcast (previously
overlay mesh would "broadcast" to one semi-random interface only).

other functions.  Not yet tested.

d1bb637cba Fixed bug with sending of broadcast frames (nexthop was not being 
set for broadcast frames).

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).
 2012-03-23 07:06:57 +10:30

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.

30e2540470 Various fixes and work towards sending MDP frames. 
Broadcast and unicast addresses are accepted.  Some frame headers
are set.  Payload is yet to be set, and ciphered &/or signed as required,
and queueing is not yet verified.

1eb4c34015 Renamed mphlr.h to serval.h 
(also some temporary debugging has been added in some places)

2a3721506b More debugging output fixes and bug fixes for overlay operation. 
Added proper check to suppress frames claiming to come from
ourselves ( necessary for squelching multi-hop broadcasts, although
we need an extra step there of having transaction ids on broadcast
frames so that we can flood smartly).

44c0765981 Various debugging code cleanups. 
Fixed some address resolution bugs (for when sender address is not
fully known).
There is still a bug in dequeuing packets though it seems.

891e3f2740 Added another debug/verbosity flag. 2012-01-10 16:29:50 +10:30

9156a68c7f Added 2nd implementation of serval packet decoder for aiding debugging 
of packet formation and decoding.
Fixed time calculation bug (duplicate time functions based off different
epochs).
Various debugging fiddles and tweaks.

144f3ee4b1 Thinned out debug messages and fixed SID generation bug to make sure 
that it always generates a valid SID, i.e., not beginning with 0.

78e3bfc4a3 Finally looks like selfacknowledgement acks get sent and can be 
decoded.  Now to actually use them ...

b6ce25ab24 Believe I have found and stemmed the memory corruption bug, although 
the trigger (poor packet header decoding/address extraction) remains.

74efa738be Now sends acks to self-announcements, but uses index-based-abbreviation 
to save space, which we have not yet implemented.

27a454ef72 Initial implementation of frame enqueuing. Queues require maxLength to be initalised to set 
congestion threshold.

37c0955494 More little fixes, especially initialising of overlay_buffers in 
overlay_payload structures.

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 
which is now used for both encapsulation and decapsulation.
Improved payload length encoding scheme to be shorter for most payload
lengths.
selfannouncement frames now get directed to stub functions for
implementation.

62a7a65fd6 More work on parsing overlay frames. Now has bare bones to think about 
forwarding frames. routing is still not implemented, so it doesn't do anything yet,
but it does try.

92768cdcd0 core of overlay mode getting closer. 
Compiles. With -N start to try to send regular packets.
