2014-04-25The data in the DHT get nodes and send nodes packets can now be ofirungentoo
variable length.
2014-04-24sendnodes packets now contains a byte indicating the number of nodesirungentoo
2014-04-23Major cleanups.irungentoo
Fixed circular dependency between DHT and net_crypto: DHT no longer depends on net_crypto. Moved the crypto request packets functions to crypto core and DHT. Cleaned up/added some defines that can be used to get the true maximum length of things like the friends request message. MAX_DATA_SIZE has been replaced in most places by more appropriate defines.
2014-04-22Decided pretty much how the handshake would work.irungentoo
Started writing the code. Astyled some files.
2014-04-21Crypto related cleanups.irungentoo
Moved Bunch of functions from net_crypto to crypto_core. decrypt_data_fast and decrypt_data_symmetric were the same thing therefore, removed decrypt_data_fast. Replaced all the crypto_secretbox_* defines with the equivalent crypto_box_* one. New define: crypto_box_KEYBYTES that is equal to crypto_box_BEFORENMBYTES.
2014-04-15Major protocol changes, this commit breaks all network compatibility.irungentoo
Removed a bunch of useless space from various structs. pack_nodes() and unpack_nodes() are now used to transmit lists of nodes for the DHT and onion parts. They provide a way to transmit both ipv6 and ipv4 nodes in the same packet in a portable way that takes as little space as possible without compression. Using pack_nodes, merged the send nodes and send nodes ipv6 packets into one packet greatly reducing the risk of amplification attacks.
2014-03-16Renamed toping to to_ping.irungentoo
2014-03-05CPU optimizations.irungentoo
Use get_shared_key() in more places.
2014-03-04CPU usage improvements.irungentoo
Shared keys for recieved DHT packets are now stored in a special array so that they don't need to be recomputed for nodes that send us lots of packets.
2014-03-01Some small DHT CPU optimizations.irungentoo
Only compute the shared key once instead of twice for received DHT requests/responses.

2013-12-11Fix a code cleanup.Coren[m]
DHT.c: - get_close_nodes(): - allow two 'indirect' nodes ('indirect' as in distant from us and therefore not tested regularly, "bad") - be consequent when testing for NULLed results, pack nodes_list dense - (logging) dump number of found entries from assoc - returnedip_ports(): - fix code cleanup, the entry to be added is about the node we were told, not about the node who told us assoc.c: - Assoc_get_close_entries(): break from loops as soon as a marking-invalid-node is hit
2013-12-11Increased some intervals/timeouts to lower network usage.irungentoo
2013-12-08Cleaned up and fixed various things.irungentoo
2013-12-08Send groupchat ips like DHT ones.irungentoo
2013-12-08Compatibility fixes.irungentoo
AF_INET/AF_INET6 can vary across devices, we introduce TOX_AF_INET and TOX_AF_INET6 to fix this.

2013-12-03get_close_nodes(): make use of assoc to find some really close nodesCoren[m]
DHT.c: - get_close_nodes(): use assoc to find nodes for the requested reference id - handle_sendnodes*(): set a proper timestamp for "heard" nodes assoc.*: - expand Assoc_close_entries by flags for additional restrictions for search - Assoc_get_close_entries(): honor the new flags - new_Assoc() prime handling: min. prime is now 5 instead of 3, and up to 25 is handled directly - Assoc_status(): added address family for seen/heard, print of hash is now fixed width
