2014-09-22Merge branch 'avatars' of https://github.com/ittner/toxcoreirungentoo
2014-09-21Remove chattiness from avatar data transfersAlexandre Erwin Ittner
The chatty approach for the avatar data transfer was intended as a security feature to add explicit delays to the transfer and prevent amplification attacks among authenticated friends. This was deemed unnecessary in the code review and, therefore, replaced by a simpler approach that sends all data in a single burst.
2014-09-21Remove support for avatar image formats other than PNGAlexandre Erwin Ittner
Support for other formats was deemed unnecessary in the code review and therefore removed. The value for the constant TOX_AVATARFORMAT_PNG is now set in stone; if the other formats become needed again in the future, this commit shall be reverted and the enum values reordered to keep compatibility.

Fixed possible issue in last commit.
2014-08-30Add support for user avatars in the core protocolAlexandre Erwin Ittner
Add a protocol and the APIs to straightforwardly support user avatars in client applications. The protocol is designed to transfer avatars in background, between friends only, and minimize network load by providing a lightweight avatar notification for local cache validation. Strict safeguards are imposed to avoid damage from non-cooperative or malicious users and to limit network usage. The complete documentation is available in docs/Avatars.md and sample code is available in testing/test_avatars.c. Code and documentation are released under the GNU GPLv3 or later, as described in the file COPYING.

2014-05-19Fixed a bug where someone could just send back the ping request packetirungentoo
with only the first byte set to 1 instead of 0 and the public key set to the one of the reciever as a valid response packet. This breaks network compatibility with all previous cores.
2014-05-17Changed cookie/cookie request packet.irungentoo
Cookie now contains the dht public key of the peer which makes more sense than including the real public key of the reciever. It means we no longer have to rely entirely on onion_client to find the dht public key of the other peer.
2014-05-14Added OOB packets to the TCP client and server.irungentoo
2014-05-11Added kill packets.irungentoo
There should be no more delay between a peer closing their client and their friend being notified of them going offline. (unless the kill packet is lost)
2014-05-08Merge branch 'master' into TCPirungentoo
2014-05-04Added arrays to store packets on send/recv in net crypto.irungentoo
Wrote down more of the protocol. Padding support has been added and implemented which will make it possible for us to pad packets to mitigate length related attacks.
2014-05-01Protocol implementation is starting to look ok.irungentoo
Still need to decide exactly how data packets will work though.
2014-04-30Added number to cookie request/response packets to prevent possibleirungentoo
DoS issue.
2014-04-29Some more work done on the middle network protocol.irungentoo
Handshake most likely has no more possible flaws to it, next thing to do is to do the same with the data packets. Wrote a couple more functions.
2014-04-28Added some functions to create/handle middle level protocol packets.irungentoo
2014-04-25The data in the DHT get nodes and send nodes packets can now be ofirungentoo
variable length.
2014-04-22Decided pretty much how the handshake would work.irungentoo
Started writing the code. Astyled some files.
2014-04-18Added text document explaining what needs to be done before TCP can be merged.irungentoo

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.
2014-03-30TCP server now sends/handles ping packets.irungentoo
2014-03-28TCP server almost ready.irungentoo
2014-03-14A bit of work done on the TCP relay server.irungentoo
2014-03-12Started writing the code for the TCP relay server.irungentoo
2014-03-11Detailed docs for TCP server pretty much done.irungentoo
Implementation coming soon.
2014-03-04Minor documentation cleanupAgatha
This commit fixes some typos and grammar mistakes. It also fixes some of the long text lines and generally makes the documentation more readable.

2014-01-19Added no_replay and added some things to the docs.irungentoo
2014-01-14Onion data packets can now be handled in onion_client.irungentoo
oniondata_registerhandler(...) can be used to register different packet types to handle them and send_onion_data(...) can be used to send these packets.
2014-01-10updated TODO.irungentoo
2014-01-09Putting the sendback outside the encrypted part of the response.irungentoo
It's more useful this way.
