Felix Lange	a47341cf96	p2p, p2p/discover, p2p/discv5: add IP network restriction feature ... The p2p packages can now be configured to restrict all communication to a certain subset of IP networks. This feature is meant to be used for private networks.	8 years ago
Felix Lange	a98d1d67d6	p2p/discover, p2p/discv5: prevent relay of invalid IPs and low ports ... The discovery DHT contains a number of hosts with LAN and loopback IPs. These get relayed because some implementations do not perform any checks on the IP. go-ethereum already prevented relay in most cases because it verifies that the host actually exists before adding it to the local table. But this verification causes other issues. We have received several reports where people's VPSs got shut down by hosting providers because sending packets to random LAN hosts is indistinguishable from a slow port scan. The new check prevents sending random packets to LAN by discarding LAN IPs sent by Internet hosts (and loopback IPs from LAN and Internet hosts). The new check also blacklists almost all currently registered special-purpose networks assigned by IANA to avoid inciting random responses from services in the LAN. As another precaution against abuse of the DHT, ports below 1024 are now considered invalid.	8 years ago

Felix Lange	1d80155d5e	p2p/netutil: new package for network utilities ... The new package contains three things for now: - IP network list parsing and matching - The WSAEMSGSIZE workaround, which is duplicated in p2p/discover and p2p/discv5.	8 years ago

ken10100147	afecb93e2e	p2p/nat: fix parameter order for AddMapping	8 years ago
Felix Lange	f5c432bcab	p2p/nat: delay auto discovery until first use ... Port mapper auto discovery used to run immediately after parsing the --nat flag, giving it a slight performance boost. But this is becoming inconvenient because we create node.Node for all geth operations including account management and bare chain interaction. Delay autodiscovery until the first use instead, which avoids any network interaction until the node is actually started.	8 years ago

Felix Lange	ee1debda53	p2p/discover: EIP-8 changes	9 years ago
Felix Lange	2871781f64	p2p/discover: fix Windows-specific issue for larger-than-buffer packets ... On Windows, UDPConn.ReadFrom returns an error for packets larger than the receive buffer. The error is not marked temporary, causing our loop to exit when the first oversized packet arrived. The fix is to treat this particular error as temporary. Fixes: #1579, #2087 Updates: #2082	9 years ago
Felix Lange	b3f1f4c673	p2p/discover: attempt to deflake TestUDP_responseTimeouts ... The test expected the timeout to fire after a matcher for the response was added, but the timeout is random and fired sooner sometimes.	9 years ago
Felix Lange	6c41e675ec	p2p: resolve incomplete dial targets ... This change makes it possible to add peers without providing their IP address. The endpoint of the target node is resolved using the discovery protocol.	9 years ago
Felix Lange	04c6369a09	p2p, p2p/discover: track bootstrap state in p2p/discover ... This change simplifies the dial scheduling logic because it no longer needs to track whether the discovery table has been bootstrapped.	9 years ago
Felix Lange	d1f507b7f1	p2p/discover: support incomplete node URLs, add Resolve	9 years ago
Péter Szilágyi	abb53644c6	p2p: always allow dynamic dials if network not disabled	9 years ago

Felix Lange	32dda97602	p2p/discover: ignore packet version numbers ... The strict matching can get in the way of protocol upgrades.	9 years ago
Felix Lange	631bf36102	p2p/discover: remove unused lastLookup field	9 years ago
Felix Lange	b4374436f3	p2p/discover: fix race involving the seed node iterator ... nodeDB.querySeeds was not safe for concurrent use but could be called concurrenty on multiple goroutines in the following case: - the table was empty - a timed refresh started - a lookup was started and initiated refresh These conditions are unlikely to coincide during normal use, but are much more likely to occur all at once when the user's machine just woke from sleep. The root cause of the issue is that querySeeds reused the same leveldb iterator until it was exhausted. This commit moves the refresh scheduling logic into its own goroutine (so only one refresh is ever active) and changes querySeeds to not use a persistent iterator. The seed node selection is now more random and ignores nodes that have not been contacted in the last 5 days.	9 years ago
Péter Szilágyi	c51e153b5c	eth, metrics, p2p: prepare metrics and net packets to eth/62	9 years ago
Jeffrey Wilcke	269c5c7107	Revert "fdtrack: temporary hack for tracking file descriptor usage" ... This reverts commit 5c949d3b3b.	9 years ago
Felix Lange	dd54fef898	p2p/discover: don't attempt to replace nodes that are being replaced ... PR #1621 changed Table locking so the mutex is not held while a contested node is being pinged. If multiple nodes ping the local node during this time window, multiple ping packets will be sent to the contested node. The changes in this commit prevent multiple packets by tracking whether the node is being replaced.	9 years ago
Felix Lange	edccc7ae34	p2p: continue listening after temporary errors	9 years ago
Felix Lange	7d5ff770e2	p2p/discover: continue reading after temporary errors ... Might solve #1579	9 years ago
Felix Lange	0d10d5a0a5	p2p: fix value of DiscSubprotocolError ... We had the wrong value (12) since forever.	9 years ago
Felix Lange	590c99a98f	p2p/discover: fix UDP reply packet timeout handling ... If the timeout fired (even just nanoseconds) before the deadline of the next pending reply, the timer was not rescheduled. The timer would've been rescheduled anyway once the next packet was sent, but there were cases where no next packet could ever be sent due to the locking issue fixed in the previous commit. As timing-related bugs go, this issue had been present for a long time and I could never reproduce it. The test added in this commit did reproduce the issue on about one out of 15 runs.	9 years ago
