* p2p: interrupt MsgPipe payload read/writeFelix Lange2015-03-191-3/+6
| | | | | | This is better because protocols might not actually read the payload for some errors (msg too big, etc.) which can be a pain to test with the old behaviour.
* p2p: log disconnect requestsFelix Lange2015-03-191-0/+1
| | | | This helps a lot with debugging.
* p2p: use package rlp to encode messagesFelix Lange2015-03-198-68/+64
| | | | | | | | | | Message encoding functions have been renamed to catch any uses. The switch to the new encoder can cause subtle incompatibilities. If there are any users outside of our tree, they will at least be alerted that there was a change. NewMsg no longer exists. The replacements for EncodeMsg are called Send and SendItems.

* eth, p2p: delete p2p.BlacklistFelix Lange2015-03-041-59/+0
| | | | | It is unused and untested right now. We can bring it back later if required.
* p2p: reject messages that cannot be written as simple RLPx framesFelix Lange2015-03-041-0/+5
| | | | | Until chunked frames are implemented we cannot send messages with a size overflowing uint24.
* p2p: restore read/write timeoutsFelix Lange2015-03-045-37/+37
| | | | They got lost in the transition to rlpxFrameRW.
* p2p: msg.Payload contains list dataFelix Lange2015-03-047-75/+25
| | | | | | | | | With RLPx frames, the message code is contained in the frame and is no longer part of the encoded data. EncodeMsg, Msg.Decode have been updated to match. Code that decodes RLP directly from Msg.Payload will need to change.
* p2p: verify protocol handshake node IDFelix Lange2015-03-041-0/+3
|
* p2p: make encryption handshake code easier to followFelix Lange2015-03-042-302/+272
| | | | | | | | | This mostly changes how information is passed around. Instead of using many function parameters and return values, put the entire state in a struct and pass that. This also adds back derivation of ecdhe-shared-secret. I deleted it by accident in a previous refactoring.

| | | | This should prevent connection drops.
* p2p: disable encryption handshakeFelix Lange2015-02-197-313/+273
| | | | | | The diff is a bit bigger than expected because the protocol handshake logic has moved out of Peer. This is necessary because the protocol handshake will have custom framing in the final protocol.

* p2p: improve read deadlinesFelix Lange2015-02-132-15/+27
| | | | | | | | 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.

* p2p/discover: add node URL functions, distinguish TCP/UDP portsFelix Lange2015-02-078-326/+532
| | | | | The discovery RPC protocol does not yet distinguish TCP and UDP ports. But it can't hurt to do so in our internal model.
* p2p: integrate p2p/discoverFelix Lange2015-02-0615-1659/+1056
| | | | | | | | | | | | 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

* eth, p2p: remove EncodeMsg from p2p.MsgWriterFelix Lange2015-01-065-23/+21
| | | | | | | | | | | | ...and make it a top-level function instead. The original idea behind having EncodeMsg in the interface was that implementations might be able to encode RLP data to their underlying writer directly instead of buffering the encoded data. The encoder will buffer anyway, so that doesn't matter anymore. Given the recent problems with EncodeMsg (copy-pasted implementation bug) I'd rather implement once, correctly.
