2013-11-30Perform string-based lookup of method-related information only onceMatthias Schiffer
2013-10-31Change error subcode for unsupported method from method name to method listMatthias Schiffer
When two peers don't support a common method, fastd should notice this in the list stage, so the method list subcode is correct. The method name subcode was a legacy of the 0.4 compatiblity code.
2013-10-29handshake: get_method() code simplificationMatthias Schiffer
2013-10-29Drop compatiblity code for fastd 0.4Matthias Schiffer
2013-10-29Handle methods as stringsMatthias Schiffer
2013-10-29Allow using libsodium instead of NaClMatthias Schiffer
As libsodium has some strange include files (like a version.h), we try to use absolute include paths whenever possible in fastd now and rename our generated headers.
2013-10-28Organize method and protocol source files into distinct source directoriesMatthias Schiffer
2013-10-24Fix maybe-uninitialized warningMatthias Schiffer
2013-10-20Don't print fastd version from handshake requests when secure handshakes are ↵Matthias Schiffer
set, instead print it on handshake finish
2013-10-20Don't send chosen method name when it doesn't matterMatthias Schiffer
2013-10-20Align handshake bufferMatthias Schiffer
2013-10-20Always check for mode and protocol mismatchesMatthias Schiffer
This was accidentially disabled in the previous commit for initial handshake requests.

2013-10-19Rename RECORD_HANDSHAKE_MAC to RECORD_TLV_MACMatthias Schiffer

2013-10-19Get rid of packet.hMatthias Schiffer
2013-10-19Add a HMAC to authenticate all handshake TLVMatthias Schiffer
2013-10-16Initiate handshake when a packet can't be sent because the local address is ↵Matthias Schiffer
invalid
2013-08-29Replace old task queueMatthias Schiffer
The handshakes are now schedules in a doubly-linked list that is maintained as a part of the peer structure.
2013-08-17Make handshake records const uint8_t* instead of void*Matthias Schiffer
This enforces explicit casting and thus avoids alignment problems.
2013-07-25Move _GNU_SOURCE define to types.hMatthias Schiffer
2013-06-09Fix some whitespace errorsMatthias Schiffer
2013-04-20Greatly improve handling of hosts with multiple IP addressesMatthias Schiffer
2013-02-23Use fastd_peer_t instead of fastd_peer_config_t in handshake codeMatthias Schiffer
Directly using the peers allows us to get rid of the inefficient get_peer() function and is necessary for adding support for unknown peers.

2012-06-04Add version string to handshakeMatthias Schiffer
2012-04-19Don't regenerate session handshake keypair for every handshake so a global ↵Matthias Schiffer
state can be used; remove the concept of temporary peers These changes will fix the possibility of a TCP-SYN-Flood-like DoS attack, at the cost of another protocol change: as we can't count request IDs when we don't know have temporary peers, request IDs are removed completely.
