emanuele-f	41bff29df6	Disable multicast peers discovery in windows	5 years ago
Teteros	ba38ab70de	Fix typo: 'enstablished' -> 'established'	6 years ago
emanuele-f	447c3ad8c3	Replace peers linked list with hash	6 years ago
emanuele-f	4eacea7d57	Little improvement	6 years ago
emanuele-f	f36814b152	Implement query peer to try p2p during send When a lot of monodirection traffic is sent, p2p can be hard to enstablish because a reply is needed in order to start the registration. Now a sending peer can query the peer information via the supernode. This is based on the following commits: - `1236f37a70` - `ad2d416510` - `5348671299` - `b2806dcde8`	6 years ago
emanuele-f	b36754eae0	Set last_p2p ib peer_set_p2p_confirmed	6 years ago
emanuele-f	3db1cab276	Split broadcast stats from other supernode stats	6 years ago
emanuele-f	0e6db6361e	Fix connection stall when idle p2p refresh occurs The edge received packets from the supernode and thought that the other peer was still active, but the other peer had dropped the p2p connection due to refresh	6 years ago
emanuele-f	f038f22a0b	Fix too many registrations going on	6 years ago
emanuele-f	623a9e480c	Improve log messages	6 years ago
fengdaolong	69e3b49bec	eliminate compilation warnings	6 years ago
yunbox	f48c170c26	Fix supernode handling REGISTER message from edge and let edge ask supernode to forward REGISTER message in case of non-p2p-reflection. This is reliable way to PUNCH UDP HOLE (following STUN spec)	6 years ago
emanuele-f	3aec02d3e6	Fix unidirectional P2P connection due to pending registration If A is directly available and B is NATted and B sends the first message to A via the supernode S, A will try to register to B via the port used by B to talk to S. This will not work as B is NAT-ted, so A must discard such pending registration as soon as it receives a P2P Registration from B.	6 years ago
emanuele-f	fb813e5438	Fix "invalid transop ID" when encryption is disabled	6 years ago
emanuele-f	52d33ed880	Fix missing destination MAC in REGISTER preventing proper P2P As explained in #109	6 years ago

emanuele-f	59011308b2	Ignore invalid community when not received from supernode The packet may be received from a multicast registration from a local peer. Fixes #107	6 years ago
emanuele-f	04226c09c8	Fix compilation warnings and little leak	6 years ago

emanuele-f	824b45a808	Add linux termination handler and print stats on shutdown	6 years ago
emanuele-f	d5387945b4	Add the -i option to specify registration interval on edge nodes Registration is bound to UDP NAT hole punching, so the edges should choose their own value.	6 years ago
emanuele-f	856dbae44c	Cosmetic changes to improve edge registration tracing	6 years ago
Luca Deri	fbc3754601	Compilation fix	6 years ago
emanuele-f	c89ece71ca	Code rework changes - Remove keyschedule leftover and adapt to new API - Fix cleanup functions - Remove unused random_device_mac	6 years ago
emanuele-f	f577d997a7	Drop keyschedule support - Legacy features are now moved to the legacy directory with readme - Keyschedule feature is not supported anymore	6 years ago
emanuele-f	e757f94efa	Initial code rework (wip) - The edge structure is now opaque - The configuration is now exposed via an API - Code cleanup: using multiple transops at once is not supported anymore	6 years ago
emanuele-f	bb07f0426e	Properly initialize AES IV and hash the AES key This implements the changes discussed in #68 and #72. This breaks compatibility with the previous AES implementation.
