* p2p: track write errors and prevent writes during shutdownFelix Lange2015-06-151-25/+57
| | | | | | | As of this commit, we no longer rely on the protocol handler to report write errors in a timely fashion. When a write fails, shutdown is initiated immediately and no new writes can start. This will also prevent new writes from starting after Server.Stop has been called.

* p2p: decrease frameReadTimeout to 30sFelix Lange2015-05-251-4/+5
| | | | | This detects hanging connections sooner. We send a ping every 15s and other implementation have similar limits.
* p2p: new dialer, peer management without locksFelix Lange2015-05-2511-1329/+2118
| | | | | | | | | | | | | | | | | | The most visible change is event-based dialing, which should be an improvement over the timer-based system that we have at the moment. The dialer gets a chance to compute new tasks whenever peers change or dials complete. This is better than checking peers on a timer because dials happen faster. The dialer can now make more precise decisions about whom to dial based on the peer set and we can test those decisions without actually opening any sockets. Peer management is easier to test because the tests can inject connections at checkpoints (after enc handshake, after protocol handshake). Most of the handshake stuff is now part of the RLPx code. It could be exported or move to its own package because it is no longer entangled with Server logic.

* p2p: decrease maximum message size for devp2p to 1kBFelix Lange2015-05-251-1/+1
| | | | | | The previous limit was 10MB which is unacceptable for all kinds of reasons, the most important one being that we don't want to allow the remote side to make us allocate 10MB at handshake time.

| | | | | | | | | | This should increase the speed a bit because all findnode results (up to 16) can be verified at the same time.
| * p2p: log remote reason when disconnect is requestedFelix Lange2015-05-142-8/+10
| | | | | | | | | | | | The returned reason is currently not used except for the log message. This change makes the log messages a bit more useful. The handshake code also returns the remote reason.
| * p2p: bump maxAcceptConns and defaultDialTimoutFelix Lange2015-05-141-2/+2

* | p2p/nat: tweak port mapping log messages and levelsFelix Lange2015-05-141-7/+6
| | | | | | | | | | | | People stil get confused about the messages. This commit changes the levels so that the only thing printed at the default level (info) is a successful mapping.
* | p2p/nat: add test for UPnP auto discovery via SSDPFelix Lange2015-05-141-0/+223
| | | | | | | | | | | | | | | | | | The test listens for multicast UDP packets on the default interface because I couldn't get it to work reliably on loopback without massive changes to goupnp. This means that the test might fail when there is a UPnP-enabled router attached on that interface. I checked that locally by looping the test and it passes reliably because the local SSDP server always responds faster.
* | p2p/nat: fix concurrent access to autodisc InterfaceFelix Lange2015-05-142-17/+63
|/ | | | | | | | | | | | Concurrent calls to Interface methods on autodisc could return a "not discovered" error if the discovery did not finish before the call. autodisc.wait expected the done channel to carry the found Interface but it was closed instead. The fix is to use sync.Once for now, which is easier to get right. And there is a test. Finally. This will have to change again when we introduce re-discovery.
* p2p/discover: fix out-of-bounds slicing for chunked neighbors packetsFelix Lange2015-05-142-32/+49

* UDP Interop. Limit datagrams to 1280bytes.subtly2015-05-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't have a UDP which specifies any messages that will be 4KB. Aside from being implemented for months and a necessity for encryption and piggy-backing packets, 1280bytes is ideal, and, means this TODO can be completed! Why 1280 bytes? * It's less than the default MTU for most WAN/LAN networks. That means fewer fragmented datagrams (esp on well-connected networks). * Fragmented datagrams and dropped packets suck and add latency while OS waits for a dropped fragment to never arrive (blocking readLoop()) * Most of our packets are < 1280 bytes. * 1280 bytes is minimum datagram size and MTU for IPv6 -- on IPv6, a datagram < 1280bytes will *never* be fragmented. UDP datagrams are dropped. A lot! And fragmented datagrams are worse. If a datagram has a 30% chance of being dropped, then a fragmented datagram has a 60% chance of being dropped. More importantly, we have signed packets and can't do anything with a packet unless we receive the entire datagram because the signature can't be verified. The same is true when we have encrypted packets. So the solution here to picking an ideal buffer size for receiving datagrams is a number under 1400bytes. And the lower-bound value for IPv6 of 1280 bytes make's it a non-decision. On IPv4 most ISPs and 3g/4g/let networks have an MTU just over 1400 -- and *never* over 1500. Never -- that means packets over 1500 (in reality: ~1450) bytes are fragmented. And probably dropped a lot. Just to prove the point, here are pings sending non-fragmented packets over wifi/ISP, and a second set of pings via cell-phone tethering. It's important to note that, if *any* router between my system and the EC2 node has a lower MTU, the message would not go through: On wifi w/normal ISP: localhost:Debug $ ping -D -s 1450 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1450 data bytes 1458 bytes from 52.6.250.242: icmp_seq=0 ttl=42 time=104.831 ms 1458 bytes from 52.6.250.242: icmp_seq=1 ttl=42 time=119.004 ms ^C --- 52.6.250.242 ping statistics --- 2 packets transmitted, 2 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 104.831/111.918/119.004/7.087 ms localhost:Debug $ ping -D -s 1480 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1480 data bytes ping: sendto: Message too long ping: sendto: Message too long Request timeout for icmp_seq 0 ping: sendto: Message too long Request timeout for icmp_seq 1 Tethering to O2: localhost:Debug $ ping -D -s 1480 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1480 data bytes ping: sendto: Message too long ping: sendto: Message too long Request timeout for icmp_seq 0 ^C --- 52.6.250.242 ping statistics --- 2 packets transmitted, 0 packets received, 100.0% packet loss localhost:Debug $ ping -D -s 1450 52.6.250.242 PING 52.6.250.242 (52.6.250.242): 1450 data bytes 1458 bytes from 52.6.250.242: icmp_seq=0 ttl=42 time=107.844 ms 1458 bytes from 52.6.250.242: icmp_seq=1 ttl=42 time=105.127 ms 1458 bytes from 52.6.250.242: icmp_seq=2 ttl=42 time=120.483 ms 1458 bytes from 52.6.250.242: icmp_seq=3 ttl=42 time=102.136 ms

* p2p/discover: implement node bondingFelix Lange2015-04-015-383/+649
| | | | | | | | | | | | | | | | This a fix for an attack vector where the discovery protocol could be used to amplify traffic in a DDOS attack. A malicious actor would send a findnode request with the IP address and UDP port of the target as the source address. The recipient of the findnode packet would then send a neighbors packet (which is 16x the size of findnode) to the victim. Our solution is to require a 'bond' with the sender of findnode. If no bond exists, the findnode packet is not processed. A bond between nodes α and β is created when α replies to a ping from β. This (initial) version of the bonding implementation might still be vulnerable against replay attacks during the expiration time window. We will add stricter source address validation later.
* p2p/discover: add version number to ping packetFelix Lange2015-04-011-0/+8
| | | | | | The primary motivation for doing this right now is that old PoC 8 nodes and newer PoC 9 nodes keep discovering each other, causing handshake failures.

* 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: 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.
