2a2e520ef5 Various fixes and additions to enable "dna node start" and "dna node stop" 
command line options to work.

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

3fed04e6cd Added some extra checks for memory corruption (of course now that I 
am looking, the problem is not happening).

90729e20b6 fixed operation of rhizome web server in overlay server mode. 2012-01-12 16:50:25 +10:30

bf9f8559f1 Various debug fiddles and conversion from select() to poll() 
(although poll() still doesn't let us monitor ordinary files
which is silly.)

670f7c51c7 Reworked Rhizome advertisement frames to include whole manifests 
inline where possible.

f8eea651b5 Changed broadcast address to include a 64bit BPI to allow filtering 
of duplicate broadcast announcements.

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.

800f8d41eb Revamped debug/verbosity control to use flags for functions of interest 
instead of general verbosity ramp.

9156a68c7f Added 2nd implementation of serval packet decoder for aiding debugging 
of packet formation and decoding.

epochs).
Various debugging fiddles and tweaks.

7e0ad31ef3 Improved handling of local addresses in overlay mesh. 
Added check to stop us sending reachability acknowledgements to ourselves.

2a2f8d752f reception and processing of advertised routes now works :) 
Indeed the core of the overlay mesh is now in place and nodes
on simple meshes discover each other. Plenty of bugs are sure
to remain.

ec22b5df0d Added infrastructure to tick route tables by progressively touching 
all neighbours and nodes over a bounded timespread so that route
ticking doesn't add excessive delay/jitter.

a91c5d29c3 added code to display overlay mesh route table (incomplete) 
fixed bug with recording routes from packets with unresolvable addresses.

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

b402aba22d More work towards getting selfannounce acks (and other packet types) 
forwarding out.

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

c3e220e5c1 Now attempts to enqueue self-annoucement ack frame (but enqueue function 
not implemented).

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.

c06b75f5c9 Fixed some sign mis-matches in overlay_abbreviations. 
Added infrastructure to keep track of receiver and sender interfaces
for multi-homed nodes.

32a5f03073 Various single-instance variable processing fixes for DNA. 
Further work on overlay mesh routing.

89c5163899 Code to calculate appropriate overlay mesh data structure sizes to give 2^n bins 
and maximised associativity in the range [4..7]. Still yet to actually allocate
the structures, though.

5dd6f9ce06 Progress towards core overlay mesh routing data structures. 2011-08-18 02:15:13 +09:30

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.

bd16fbbf5b Address lookup from cache works :) 
This gets us a functional system once we add the code to send PLEASEEXPLAIN
messages to request resolutions.

cf778e1efd Various further work on overlay mesh. 
Now resolves some kinds of abbreviated address, and queues up
the need to remind peers of abbreviation schemes it does not support.

229850c8d7 Overlay mode with address summarisation closer to working. 
Self-announcements now abbreviate addresses, and in theory they
get expanded on reception -- but more testing and coding required.
 2011-08-15 09:27:29 +02:00

0cf6e545c4 Fixed select() problems with dummy interfaces and EOF reporting. 
Dummy interfaces now work.
Supressed lots of debug messages.
 2011-08-14 10:36:39 +02:00

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

6e172c76c9 Fixed broadcast address discovery to work on Mac. 
Fixed Linux assumptions.
Added parsing of overlay mesh interface specification from command line.
Separated overlay mesh code out into several files.
Overlay mesh is still far from working, but the infrastructure is coming together.
