Felix Lange	32a9c0ca80	p2p: bump devp2p protcol version to 3 ... For compatibility with cpp-ethereum	10 years ago
Felix Lange	fd3e1061e0	p2p: handle disconnect before protocol handshake	10 years ago
Felix Lange	cf754b9483	p2p/discover: fix race in ListenUDP ... udp.Table was assigned after the readLoop started, so packets could arrive and be processed before the Table was there.	10 years ago
Felix Lange	5cc1256fd6	p2p: ensure we don't dial ourself ... addPeer doesn't allow self connects, but we can avoid opening connections in the first place.	10 years ago
Felix Lange	7101f44998	p2p: add I/O timeout for encrytion handshake	10 years ago
Felix Lange	22ee366ed6	p2p: fix goroutine leak for invalid peers ... The deflect logic called Disconnect on the peer, but the peer never ran and wouldn't process the disconnect request.	10 years ago
Felix Lange	5110f80bba	p2p: improve read deadlines ... There are now two deadlines, frameReadTimeout and payloadReadTimeout. The frame timeout is longer and allows for connections that are idle. The message timeout is still short and ensures that we don't get stuck in the middle of a message.	10 years ago
Felix Lange	170eb3ac68	p2p/discover: map listening port using configured mechanism	10 years ago
Felix Lange	82f0bd9009	p2p/discover: code review fixes	10 years ago
Felix Lange	d0a2e655c9	cmd/ethereum, cmd/mist, eth, p2p: use package p2p/nat ... This deletes the old NAT implementation.	10 years ago
Felix Lange	1543833ca0	p2p/nat: new package for port mapping stuff ... I have verified that UPnP and NAT-PMP work against an older version of the MiniUPnP daemon running on pfSense. This code is kind of hard to test automatically.	10 years ago
Taylor Gerring	db24fb792c	Move standard fields to LogEvent	10 years ago
Taylor Gerring	d53e5646ec	Use strongly-typed objects	10 years ago
Felix Lange	9915d3c3be	p2p/discover: deflake UDP tests	10 years ago
Felix Lange	028775a086	cmd/ethereum, cmd/mist: add flag for discovery bootstrap nodes	10 years ago
Felix Lange	2cf4fed11b	cmd/mist, eth, javascript, p2p: use Node URLs for peer suggestions	10 years ago
Felix Lange	e34d134102	p2p: fixes for actual connections ... The unit test hooks were turned on 'in production'.	10 years ago
Felix Lange	8564eb9f7e	p2p/discover: add node URL functions, distinguish TCP/UDP ports ... The discovery RPC protocol does not yet distinguish TCP and UDP ports. But it can't hurt to do so in our internal model.	10 years ago
Felix Lange	5bdc115943	p2p: integrate p2p/discover ... Overview of changes: - ClientIdentity has been removed, use discover.NodeID - Server now requires a private key to be set (instead of public key) - Server performs the encryption handshake before launching Peer - Dial logic takes peers from discover table - Encryption handshake code has been cleaned up a bit - baseProtocol is gone because we don't exchange peers anymore - Some parts of baseProtocol have moved into Peer instead	10 years ago

Felix Lange	12224c7f59	p2p/discover: new package implementing the Node Discovery Protocol	10 years ago

zelig	54252ede31	add temporary forced session token generation	10 years ago
zelig	faa069a126	peer-level integration test for crypto handshake ... - add const length params for handshake messages - add length check to fail early - add debug logs to help interop testing (!ABSOLUTELY SHOULD BE DELETED LATER) - wrap connection read/writes in error check - add cryptoReady channel in peer to signal when secure session setup is finished - wait for cryptoReady or timeout in TestPeersHandshake	10 years ago
zelig	20aade56c3	chop first byte when cryptoid.PubKeyS is set from identity.Pubkey() since this is directly copied in the auth message	10 years ago
zelig	1f2adb05b5	add initial peer level test (failing)	10 years ago
zelig	4afde4e738	add code documentation	10 years ago
zelig	364b783281	changes that fix it all: ... - set proper public key serialisation length in pubLen = 64 - reset all sizes and offsets - rename from DER to S (we are not using DER encoding) - add remoteInitRandomPubKey as return value to respondToHandshake - add ImportPublicKey with error return to read both EC golang.elliptic style 65 byte encoding and 64 byte one - add ExportPublicKey falling back to go-ethereum/crypto.FromECDSAPub() chopping off the first byte - add Import - Export tests - all tests pass	10 years ago
zelig	58fc2c679b	important fix for peer pubkey. when taken from identity, chop first format byte!	10 years ago
zelig	923504ce3d	add equality check for nonce and remote nonce	10 years ago
zelig	2e868566d7	add minor comments to the test	10 years ago
zelig	e252c634cb	first stab at integrating crypto in our p2p ... - abstract the entire handshake logic in cryptoId.Run() taking session-relevant parameters - changes in peer to accomodate how the encryption layer would be switched on - modify arguments of handshake components - fixed test getting the wrong pubkey but it till crashes on DH in newSession()	10 years ago
zelig	1803c65e40	integrate cryptoId into peer and connection lifecycle	10 years ago
zelig	489d956283	completed the test. FAIL now. it crashes at diffie-hellman. ECIES -> secp256k1-go panics	10 years ago
zelig	076c382a74	handshake test to crypto	10 years ago
zelig	3b6385b146	handshake test to crypto	10 years ago
zelig	714b955d6e	fix crash ... - add session token check and fallback to shared secret in responder call too - use explicit length for the types of new messages - fix typo resp[resLen-1] = tokenFlag	10 years ago
zelig	b855f671a5	rewrite to comply with latest spec ... - correct sizes for the blocks : sec signature 65, ecies sklen 16, keylength 32 - added allocation to Xor (should be optimized later) - no pubkey reader needed, just do with copy - restructuring now into INITIATE, RESPOND, COMPLETE -> newSession initialises the encryption/authentication layer - crypto identity can be part of client identity, some initialisation when server created	10 years ago
