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

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

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).

ba645687f6 Progress towards overlay mode advertising rhizome bundles. 
(but some evil memory corruption error if overlay mode and
rhizome are both enabled.)

ad88045ca6 Rhizome web server progress. Still not working, but poll() now is 
doing what it should, and we are detecting closed sockets.
Now to add some parsing etc.

6ec1d6032f Further work towards sqlite3 backend for rhizome. 
Wrote function to store file to db iff it is not stored already,
and update the priority flag on the stored file.
Uses blobio to progressively load large blobs to make it friendly
on small memory systems.

f55a6525a2 Added hooks and code to build and link to NaCl static library

nasty run-time suprises)

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.

8aa57edee3 Added code to add node advertisements to interface tick packets. 
Looks like it works.  No code to decode it yet.

f301929026 Rejigged node structure to include score and advertisment history 
information that can be used to help us prioritise which nodes
get advertised when.

0cb65c4a87 Cleaned up other references to interface in overlay_node_observation.

4303cc60d5 Fixed some bugs with route ticking infrastructure. 
Added call to tick each neighbour.
 2011-09-13 01:14:09 +09:30
gardners
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.

d7aa6bcc01 Self-announcement acks are now logged into node observations. 
Untested.

c65bc0d764 Stub in place for processing selfannounce acks. 
Some bug fixes with address expansion.
 2011-09-11 17:21:09 +09:30

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.

b0680bd6e0 Now does send acks to self-announcements. 
Considerable work towards supporting 1-byte abbreviations of
addresses. But now there seems to be a memory corruption.
 2011-09-05 16:30:50 +09:30

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

7c4f07279b Harmonising edits so that it builds again. 2011-09-05 14:58:12 +09:30

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.

37c0955494 More little fixes, especially initialising of overlay_buffers in 
overlay_payload structures.
 2011-09-05 12:34:54 +09:30

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.
 2011-09-05 12:19:53 +09:30

f86089c9c8 Neighbour score calculation more or less in place, 
just need to add aging of concatenated observation records so that
scores start dropping as soon as a node stops being observed.

c06b75f5c9 Fixed some sign mis-matches in overlay_abbreviations.

for multi-homed nodes.

1d6d744067 More work towards overlay mesh. 
Added single byte append to overlay_buffer type.

Probably other stuff, too.

and most recent observations of other nodes from other nodes.

857bf9c11e All interfaces now use a common synchronised tick-clock so that we can 
more easily keep track of node reachability.

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.

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.
